We propose architecture based on which vehicles are able to find the best path toward their destination using real-time traffic information thus, travel time is reduced and roads traffic capacity is increased. Pervious system, aiming at the same goal, use traffic flow prediction thus their information is not real-time and even precise. Moreover, some systems use GPS data but due to coverage limitations (in dense city environments, tunnels) permanent accessibility may not be provided. In this paper, thus, we propose architecture for such a system based on communication between vehicles and road side infrastructure. We first propose a scheme for Road Side Unit (RSU) placement so that the maximum coverage with minimum numbers of RSUs is achieved. Then an algorithm is proposed for information gathering though which real-time traffic information is circulated between all RSUs. Finally this information is used for navigation of vehicles toward their destination during city trips. Results of simulation study conducted by NTCUns shows the good performance of the proposed idea. Manuscript profile -

The fuel filling stations network is one of the components of the municipal services network that acts as a fuel supplier to the intercity transportation sector, which is important in terms of traffic considerations, urbanization, safety and the environment. One of the most important factors surrounding fuel supply stations (petrol stations) is their proper location. Multi-criteria decision-making models (MCDMs) are now becoming an expanding tool for addressing complex spatial decision-making problems. There are several methods in making multi-criteria decisions. Studies and evidence show that multi-criteria decision-making methods, especially the combined methods between them, provide accurate results for spatial decision-making. Due to the high population density and the density of internal and external passage overnight and the passage to the adjacent areas, Tehran's region 17 shows the need for fuel efficiency and optimal location. Therefore, the purpose of this study was to determine the appropriate location of pump-gas stations in the 17th district of Tehran and to investigate the position of the existing sites in this area, using the GIS and utilizing the fuzzy AHP combined method. Not. The research method has descriptive-analytical and applied nature in this evaluation. In order to achieve these goals, suitable criteria, consistent with the studied area and different methods have been used. Finally, by using paired comparisons and experts' opinion and calculations by the fuzzy AHP method, the final weight of the criteria has been determined. The results of the integration of information layers in ARCGIS software, while identifying suitable locations for building new stations, have analyzed the location of gas station positions, which shows that each of the 2 existing locations in the 17th district of Tehran in an appropriate and optimal position they are not.

In this area, the Asmari Formation with a thickness of 364 m have been exposed as a sequence of thin, medium, thick, and massive carbonate rocks. Twelve microfacies types have been distinguished on the basis of depositional textures, petrographic analysis and fauna. These carbonate microfacies belong to four major sub-environments including tidal flat, lagoon, bar/ shoal, and open marine. Absence of turbidite deposits, reefal belt and gradual changes in facies indicated that the Asmari Formation was deposited in a homoclinal carbonate ramp environment. The main diagenetic processes includes: dolomitization, cementation, micritization, dissolution, and compaction. Petrographic evidence and variation of major and minor element and compare this information with modern aragonite warm water and calcitic cool to cold temperate carbonate and originally aragonite mineralogy of Ordovician sub-tropical carbonate, the calcite mineralogy of Permian sub-polar cold water of Tasmania, the Upper Jurassic aragonite Mozduran limestone, the Ilam carbonate formation, and the Fahliyan Formation indicate that original carbonate mineralogy was aragonite in the Asmari Formation. High Sr/Na ratio suggests original aragonite mineralogy. Variation of Sr and Na values versus Mn confirm replacement of aragonite by calcite during the two stages of diagenetic stabilization. The bivariate plot of Sr/Ca versus Mn shows that Asmari limestone have been influenced by meteoric diagenesis in a closed to semi-closed diagenetic system. Manuscript profile -

Skarns have formed in direct contact with intrusions in carbonate rocks. The Panah-Kuh granitic rocks are mainly metaluminous, calc-alkaline with I-type granitoid characteristics. Biotite and amphibole phenocrysts are the most abundant hydrous mineral in the Panah-Kuh granite. Chemical analysis of biotite and amphibole in granitic rocks in Panah-Kuh shows that the total Al (TAl) content of them can be used as a useful indicator for distinguishing between mineralized and nonmineralized granitic rocks. A good positive correlation is showed between the TAl content and the formation pressure of the granitic rocks estimated by biotite and hornblende geobarometers. These facts suggest that the TAl content of biotite and hornblende can be used to estimate the solidification pressure of the granitic rocks. According to the obtained biotite and amphibole geobarometers, it is estimated that Panah-Kuh Fe-Cu skarn deposit was formed at pressures of 1-2 kb similar to Yaguki, Kamaishi and Tanazawa Fe-Cu deposits in Japan. Therefore, biotite and amphibole geobarometers of granitic rocks may be a useful indicator in the exploration of skarn ore deposits related to granitic rocks. Manuscript profile -

This formation in the Mansouri Oilfield is composed of the mixture of silisiclastic - carbonate deposits which silisiclastic deposits are known as the Ahwaz Sandstone Member. Rock typing is a process in which geological facies determined with their dynamic behavior. Each flow unit is related to flow zone indicator, thus zoning of a reservoir using of flow zone indicators and identification of Flow units can be used to evaluate the reservoir quality based on relationship between porosity and permeability. To evaluate the reservoir quality and determining spatial distribution of petro-physical indexes in the Asmari Formation Sandstone, porosity-permeability relationship as well as their relationship with the rock types is used and finally Flow Units and Rock Types have been identified. In this study, the Asmari Formation Sandstone is divided into four flow units A, B, C and D. Within recognized flow units, flow unit C is the best one in the terms of reservoir quality and flow unit D also has a good reservoir quality. Comparison of determined flow units with porosity logs (neutron, density and sonic), it is observed that sandstone successions of Asmari reservoir affected by diagenetic processes like fracturing, dissolution, dolomitic cementation and hydrocarbon migration before cementation and flow units C and D are more extended, so porosity logs show good reservoir quality in this interval of Asmari succession. Thus it can be deduced that using hydraulic flow units, we can determine rock types groups in wells with core and then extrapolate the results into uncored wells. Manuscript profile -

The metamorphic rocks of the area include chlorite schist, epidote-amphibole schist, mica schist, marble, quartzite and metamorphosed gabbrodiorite. Metapelites are the focus of the present study, since they have recorded mineral appearances and deformational phases due to suitable composition. Petrographic studies show that three types of metapelites, including biotite schist, garnet schist and muscovite schist are present. Retrograde metamorphisms, owing to pressure and temperature decrease during exhumation are recorded in the Kuhe Arqoon rocks. The main deformational features include andaluse extinction, mineral stretching, pressure shadow and preferred orientation of minerals. Using petrographical studies and considering relation between structures and porphyroblasts and matrix (microstructures), three main deformational phases were determined for the area, among them the second deformational phase was the strongest. This deformation has produced the main foliation in the rocks. The weakest phase was the third deformational phase, which was not accompanied by metamorphism. Contemporarily with D1 deformational phase, M1 metamorphic phase occurred, crystallizing chlorite, muscovite, quartz, biotite and garnet. M2 metamorphic phase was coeval with D2 deformational phase. Mineral assemblage of M2 is biotite, muscovite, quartz and garnet. During the weak D3 deformational phase, chlorite is formed with weak orientation in the rocks. Manuscript profile -

It is composed of limestone dolomite, dolomitic limestone, sandy dolomitic limestone, sandstone, siltstone and shale. Study of 1100 thin sections from available cores at this well as well as the well’s numeral data, porosity and permeability of cores, indicates that the most important diagenetic processes is anhydritic cement with different types of textures. It appears as poikilotopic, porefilling and pervasive, nodular, fracture filling, sparce crystals, and evaporite veins. During different steps of diagenesis, these texture show replacement and pore filling porosity that have affected different facies to some degrees. Results of this study show that anhydrite cement occurs mainly in dolomitic and sandstone facies and to some extent, affected the reservoir quality. This is due to the effect of sulphate rich brines during dolomitization. Where the presence of anhydrite cements in limestone facies is sparse and rare, it has little effect on reservoir quality. However, pore filling and pervasive anhydrite texture filling all pore-space in dolograinstone and dolopackstone grain-supported facies during shallow burial intensively reduced reservoir quality. Dissolution of cements at later stage of diagenetic processes (creating secondary porosity) improved reservoir quality. In addition, solution of texture poikilotopic anhydrite in sandstone facies and repercipitated as patchy anhydrite with poikilotopic texture, results in reduction of porosity but it doesn’t make any changes in throat pores. Hence patchy anhydrite with poikilotopic texture that reduces porosity converts the sample from Lucias class 2 to class 1. Manuscript profile -

These intrusions have gabbro-dioritic compositions and granular, intergranular, ophitic and subophitic textures. Plagioclase, augitic clinopyroxene, amphibole and biotite are their main minerals and olivine, phlogopite, alkali feldspar, apatite, magnetite and sphene are their minor and accessory minerals. Their secondary minerals composed of serpentine, zeolite, chlorite, sericite, prehnite, sphene, uralite, quartz and calcite. These rocks plotted in gabbro-diorite realm in chemical classification diagrams. Geochemical trends of samples in major and trace elements variation diagrams versus differentiation index and in incompatible-incompatible and incompatible-compatible diagrams indicate the liquid line of descent and differentiation relations between samples. In the chondrite and primitive mantle normalized diagrams, enrichment in LREEs and LILEs, depletion in HREEs, absence of Eu anomaly, positive anomalies in K, Ba, Rb and Sr in all samples and strongly depletions in Nb and Ta in some samples and absence of depletion in Ti and P, are the characteristics features of these rocks. This indicates the crustal contamination of the mafic mantle magma formed these rocks. These rocks rather have the features of proto-back-arc basin (BAB) alkaline basaltic magmas, not the characteristics of the subduction related rocks. The dependence of these rocks to the back-arc basin basalts can be confirmed by different tectonic setting discrimination diagrams. It seems that the primary basic magma of these rocks has been generated from partial melting of an enriched mantle source under the continental lithosphere of Central Iran in an extensional proto-back-arc basin, during Late Oligocene time and intruded in lower part of Lower Red Formation.

In this study, in order to evaluate geochemical characteristics of Ilam, Laffan and Sarvak formations in well NH01 in Nosrat Oil Field, geochemical data including preliminary and detailed Rock Eval Pyrolysis, bitumen extraction and Gas Chromatography on 15 cuttings samples (7 samples from Ilam, 6 samples from Laffan and 2 samples from Sarvak formations) were used. Results of pyrolysis indicated that most samples have a mixture of kerogen type II and III that often tend to be kerogen type II. In general, Ilam, Laffan and Sarvak formations are poor in organic matter and have lower hydrocarbon potential and maturities. Results of liquid chromatography for Ilam and Sarvak samples indicated that these samples are paraffinic in origin. Gas chromatography suggested that Ilam and Sarvak formations deposited in anoxic conditions containing organic matter mostly derived from marine environment with subordinate amounts of terrestrial input.

In order to recognize facies changes and depositional environments of the Shurijeh Formation in east of the Kopet Dagh, 3 stratigraphic sections including Baghak and Mozduran surface sections and a well from Khangiran gas field were selected and studied. Field surveys together with microscopic studies of 311 thin sections reveal that depositional environment of the lower part of the Shurijeh Formation is mainly interpreted as fluvial environment, especially braided and meandering rivers. In the upper part of this formation, coastal plain and tidal flat facies, which locally contain lagoon and shoal sediments, are observed. Manuscript profile -

Based on lithological studies, it is mainly composed of a periodic arrangement of marly limestone with very thick, thick and medium bedded limestone layers and in some parts it consists of dolomitic layers. The lower contact of the Asmari Formation with Pabdeh Formation is gradual and its upper contact with the Gachsaran Formation is conformable with some sharp lithological changes. Based on change in thickness of layers, color and lithology, this carbonate sequence is subdivided into three lithological units. In Biostratigraphic studies, 28 species belonging to 41 genera of foraminifera were recognized. According to recognized biozone and foraminifera assemblages, 4 biozones and one undetermined zone were classified according to Laursen et al., 2009. The age of the Asmari Formation in this section is Oligocene (Rupelian-Chatian) to Early Miocene (Aquitanian-Bourdigalian). Manuscript profile -

The study is based on the lithosratigraphy, biostratigraphic framework (in the context of European standard biozonation), microfacies, paleoenvironmental interpretation and sequence srtatgraphic concepts. In this section, only f to c1 members of the Qom Formation can be differentiated. The biostrtigraphic results revealed that the benthic foraminiferal composition of the studied section has close affinities with coeval assemblages in Western Tethys and the Middle East. The larger foraminifera associations in the Qom Formation mark the SBZ 23 to 25 zones, referring to a time span from the late Chattian to Burdigalian. Based on the micropaleontological studies, the age of late Chattian (SBZ 23) is ascribed to c1 member which previously considered as Aquitanian, in East of Siah Kuh surface section. Sedimentary environment of the Qom Formation is related to a carbonate ramp platform. Based on sedimentary texture and percentage of skeletal and non skeletal allochems, 1 lithofacies and 13 microfacies from inner to outer ramp were determined. The sequence stratigraphic studies led to the determination of four 3rd order sequences. The first sequence with the Chattian age includes c1 and c2 members. The second sequence with the Aquitanian age includes c3, c4 and d members. The e and f members belong to third and fourth sequences with the age of Burdigalian. Manuscript profile -

The study of microfacies, sedimentary environments and sequence stratigraphic features of the Qom Formation in this area can help to understand the situation of the Qom sedimentary basin in the northern part, bordering the Alborz zone. 166 samples of the Qom Formation in Deh Namak section in the northwest of Garmsar are investigated. Microfacies analysis of these sedimentary rocks indicates that according to sedimentary environment they consist of nine microfacies belonging to four facies belts including tidal flat, agoon, shoal/reef sediments and slope of platform. Due to the absence of the gravitational and turbidity sediments and abundance of reef/shoal sediments, a rimmed carbonate shelf depositional environment is suggested in which more sediments were precipitated in shallow water. In this model, deep facies of the basin did not spread and the deepest facies belong to the slope. Also, sequence stratigraphic studies show that the Deh Namak section is composed of four sedimentary sequences of third- order, two types II and one type I sequence boundaries were recognized in this formation.

The thickness of the Shahbazan Formation in the studied well is 228 meters. This formation consists mainly of limestone and dolomite. The lower boundary of the Shahbazan Formation with the Pabdeh Formation is conformable and its upper boundary with Asmari Formation is marked by an unconformity. The Shahbazan Formation in the studied well is considered middle Eocene (early Lutetian) to late Eocene (Priabonian) in age. Fourteen microfacies types were distinguished based on their depositional texture, petrographic analysis and fauna in the studied well. The sediments were deposited in open marine, bar and lagoon subenvironments. Based on distribution of microfacies, it seems that the lower and upper parts of the Shahbazan Formation were deposited in two types of carbonate settings. The lower part was deposited in an open shelf setting, while, a homoclinal ramp were recognized for the upper part. The lower and upper parts of the Shahbazan Formation can be divided into two subenvironments, middle and outer shelves and middle and inner ramps, respectively. The production rate and diffusion coefficient and the tectonic conditions are the effective factors on the evolution of the platform from an open shelf setting to a homoclinal carbonate ramp .

The metamorphic rocks of the study area form the western part of the Muteh-Golpaygan metamorphic complex, situated in the central part of the Sanandaj-Sirjan Zone. These rocks are separated from younger non-metamorphic rocks by normal faults. The main lithology is schist, marble, gneiss and amphibolite. These rocks confirm three successive and prograde deformations as well as three stages of metamorphism. The first stage of deformation created isoclinal and intrafolial folds, first generation boudins and first generation foliation in amphibolite to greenschist facieses. The second stage of deformation is identified by formation of second generation folds, second generation boudins and mylonitic foliation in a greenschist facies. Finally, the third stage of deformation occurred in ductile-brittle condition and is associated with decrease of deformation. The contact metamorphism is the result of the several intrusive rocks that were identified by formation of the metamorphic aureoles, hornfelse or scarns, and in microscopic scale by recrystallization of new minerals or obliteration of former structures.

The abundance and diversity of the ostracods taxa such as Paracypris، Aurila ،Ruggieria ،Loxochoncha ، Krithe، Xestoleberis, Cytherella mostly suggest a marine environment with normal salinity and warm climate from ecological point of view. However, the increase and decrease of these taxa in the studied section indicate the diversity and abundance changes is related to environmental changes. In fact, this shows the instability of the environmental conditions which seems to be affected by the changes of food and oxygen values, and water turbulence. Based on ostracods assemblages, an Early Miocene age ( Aquitanian- Burdigalian) is exclusively suggested for the e Member of the Qom Formation at Cheshmeh Boroun stratigraphic section.

Based on petrography, minerals of basaltic rocks formed in two stages: first magmatic minerals include in quartz, feldspar, pyroxene, amphibole, and then metasomatic minerals: tremolite - actinolite, chlorite, epidote, calcite, biotite, albite and iron oxide. Metasomatism changed rock forming minerals but most of clinopyroxenes are fresh compared to other minerals. Mineral chemistry of clinopyroxene is used for recognition of magma nature and tectonic settings of parent magma of the Hormoz Formation. The average composition of clinopyroxens of Gachin salt dome is augite (Wo27.66 En45.44 Fs26.91), clonopyroxens of Hormoz Island salt dome is augite –diopsid (Wo43.36 En32.71Fs23.93). These minerals are Ca-Eskola. Geochemical diagrams based on clynopyroxens composition show that the background of Hormoz salt dome samples are volcanic arc basalts and Gachin salt dome samples are intraplate tholeiitic basalts and they had sub-alkaline nature. Their forming temperatures of clinopyroxens are 875oc for Hormoz clinopyroxenes and 997oc for Gachin clinopyroxenes and forming pressure is less than 2kb. Manuscript profile -

This succession is the main producing reservoir of the Jurassic system in the Arabian plate. This research was carried out based on core (thin section, porosity - permeability, capillary pressure data) and well log data to study the depositional environment and diagenetic effects on reservoir quality of the upper part of the Surmeh Formation. Petrographic investigations led to recognized nine microfacies which were classified in four facies belt including supratidal, intertidal, lagoon and shoal which were deposited in an arid homoclinal carbonate ramp. Diagenetic processes affected reservoir quality of identified microfacies. Among them, dolomitization, anhydritization and cementation are the main effective processes. Dolomitization increased reservoir quality but the anhydritization and cementation decreased reservoir quality. It is important to note that relevant reservoir quality is improved by development of shallow marine facies associations and secondary diagenetic events. Based on the porosity, permeability and mercury injection pressure data, anhydrite and anhydrite bearing mudstone have very low reservoir quality whereas ooid and bioclastic pack ston to grainstone have the best reservoir quality.

Host rock of this deposit is lower Cretaceous dolomitized carbonate rocks. In this area there are three major rock units. The Sangestan Formation as the lowest unit, is composed of shale and siltstone with calcarenitic interbeded layers. This unit is overlain by ankeritic massive dolomite and dolomitic limestone of the Taft Formation. The Abkouh Formation at the top, is composed of cherty or argillaceous limestone with massive reefal limestone. The host rock of deposit in the lower Cretaceous carbonate horizon along with other geological evidence indicate that this deposit has been primarily formed similar to the Mississipi Valley-type deposits. This conditions include carbonate and evaporatic sequences, special hydrothermal dolomitized horizons, lack of the effects of igneous intrusions and the presence of the important controling faults. Based on the observations, it can be concluded that the primary ores have been of the sulphide type including sphalerite, galena and pyrite. Due to their exposure to superficial oxidizing conditions and undergoing changes, the primary sulphide ores, have been converted into nonsulphide ore body. As a result, the primary sulphide ores have been changed into secondary minerals such as hemimorphite, smithsonite, cerusite and anglesite. In many cases, the nonsulphide minerals established in the structural fractures and fissures, shows the colloform texture. Therefore, it can be accepted that this type of minerals were formed under the effect of low temperature hydrothermal fluids.There are two types of fluid inclusions (type I: L and type II: L+V) in the carbonaceous ore bearing veins. On the basis of microthermometric study, the homogenization temperatures is between 150-260 °C. The salinity of fluid inclusions is low to intermediate (0.33-14.26 wt. % NaCl equivalent). Heating depressurization due to reduced pressure to boiling with low CO2 bearing fluid (0.62-0.98 gr/cm3) is the main mechanism of deposition. Based on evidence such as the nonhomoginity in filling degree of fluid inclusions, existence of a few vapor-rich phase shows boiling of ore fluid in faulted and fracture zones. Manuscript profile -

So tha MorePlastic behavior and significant thickness of the Gachsaran incompetence formation on top of middle carbonate units in the sedimentary sequence of the southern Dezful Embayment led to the emergence of different styles of folding above and below of this formation. So that the structures in the upper and lower parts of this formation are completely separated and do not match each other. In the upper anticlines, above the Gachsaran horizon, the calculation of the limbs angle, the main thrust slope and the percentage of forelimb thickening indicate the fault detachment fold style. This style marks the geometry of fold at the early stage of the development of this anticline. Also the seismic profiles below the Gachsaran horizon also show the fault-propagation folding style. In the south Dezful Embayment, folding in the Gachsaran Formation occurs with shorter wavelengths in the form of disharmonic folds. This folding acts as the decoupling surface for the lower folds so that the synclines in this moving horizon directly cover the lower anticlines. The rounded folds in the carbonates in lower anticline are the imposed folds associated with steepened up reverse faults, detached on the basal decollement level and ultimately faulted by progressive deformation. The interpretation of seismic sections in the southern Dezful Embayment shows that lateral migration occurs in the salt units of the GS2 and GS4, and the upper and lower units of the Gachsaran Formation do not play a role in salt migration. Lateral migration in Miocene salts of the Gachsaran Formation is accomplished by the growth of sub-anticline during folding and loading of upper formation at the upper Gachsaran Formation.

Stretches of the boudins, which occurred during the first stage of the regional deformation, are measured in seven stations. The data are used for two dimensional finite strain analyses by Mohr circle. The results indicate the ellipticity of the strain ellipsoids vary between 1.05 to 1.36, and the maximum shear angle is between 4 to 20 degrees. These results are in agreement with field observations indicating dominant pure shear deformation during the first stage. This deformation is marked by generation of continuous folds and chocolate box boudins. These types of boudins were formed due to the stretching in two directions. Results of two dimensional strain analyses also show half to one time positive volume change during first stage of deformation. Manuscript profile -

The in-situ stress MoreEstimation of in-situ stress tensor in sedimentary basins using information obtained from exploration and development oil and gas wells during the drilling and logging process may be used for estimation of in-situ stress tensor in sedimentary basins. The in-situ stress magnitude and orientation and the resulting stress regime around the studied wells have been several application in secondary recovery programs from hydrocarbon reservoirs as well as wellbore stability analysis. In this paper, the magnitude of in-situ stress is estimated by using abovementioned data in some oil wells located in the south west of Iran. Increasing the oil production by hydraulic fracturing design and sand control in the multi-layer reservoirs such as the Marun giant oil field with loose sand horizons and also improving drilling performance in the Gachsaran formation¬ requires knowledge about the prevailing stress conditions. This research, tries to analyze the stress regime of the Asmari and Gachsaran Formations around the selected wells in the Marun and Lali fields using constructed Mechanical Earth Models (MEM) and their differences are discussed. The calculated stress magnitudes in studied wells indicate a significant drop in magnitude of horizontal stresses from the Gachsaran to Asmari reservoirs in the Marun oil field. The magnitudes of the three principal stresses resulted that SHmax is the maximum principal stress and the Shmin is the minimum principal stress, thus a strike-slip stress regime (SHmax>Sv>Shmin) dominates in the Gachsaran sequence and the Asmari formation of the Lali oil field. however, in the Gachsaran formation of Marun giant oil field, stress regime is reverse-strike slip but normal stress regime is dominated in it's Asmari reservoir. The In-situ stress condition indicates that the structural condition and the depth difference of these structures plays an important role in the tectonic stress regime changes. Manuscript profile -

To study the Faraghan Formation some thin sections were prepared from cuttings of some wells in the central part of the Persian Gulf and then they were studied. Results show of this study that the Faraghan Formation consists of quartz arenite, sandy siltstone and sandy claystone petrofacies and carbonate mudstone, bioclast wackestone and bioclast packstone microfacies. Based on sedimentary characteristics and spatial relationships between the petrofacies, this formation was deposited on a linear shoreface environment (floodplain, shoreface and offshore sub-environments). Main diagenetic processes consist of compaction, dissolution, cementation, neomorphism, sericitization and dolomitization. Heterogeneity of the Faraghan Formation lithology and variety of environmental conditions and diagenetic features make this formation a good candidate for hydrocarbon reservoir studies.</p> Manuscript profile -

Then, using the EPM model, the erosion zoning map of this basin located around the Saveh dam was prepared and its annual precipitation rate was estimated. In the following, the output of the model was compared with the hydrometric method. According to the results of EPM model, sediment yield from stations of Poledoab, Bazaneh, Toureh and Shazand using EPM model are 288103.81, 18963.83, 43079.2 and 20583.76 respectively, whereas hydrometric method shows values 335285.42, 23937.42, 36459.09 and 42781.69 ton per year, respectively. Also comparison of EPM model with hydrometric method shows a good correlation. Results show accuracy of 86%, 82%, 48% and 79% for Poledoab, Toureh, Shazand and Bazaneh stations, respectively. Assessments show that EPM model with acceptable accuracy provides good results in order to predict the mximum annual sediment yield. Manuscript profile -

In most parts of the central Iran, the Qom Formation conformably overlies the Lower Red Formation with an erosional discontinuity and is in turn conformably overlain by the Upper Red Formation. In the Madabad celestite deposit (south of Zanjan), the Qom Formation is composed of 190 m of medium to thick-bedded and massive limestone, marly limestone and marl. Five main microfacies are identified in the limestone units of the Qom Formation in the Madabad area. These microfacies probably were deposited on a shelf carbonate platform. Petrographic studies suggest original calcite mineralogy for limestone units of the Qom Formation in the Madabad area. Geochemical studies (Ca, Mg, Na, Sr, Mn and Fe) also represent the original calcite mineralogy in a closed diagenetic system with low dissolution rates.

Its shortening resulted from the Zagros orogeny in Paleogene. In order to identify the minerals at the detachments, XRD analysis was carried on the samples of Shemshak and Chamanbid Formations. On the other hand, the estimated shortening in the west and central Kopet-Dagh in two north-south cross-sections, were calculated in the 3D software of Move-Midland Valley, using previous data, field observation, geological maps and satellite images. The study of the three-dimensional cross sections, which is considered to be the innovations of this research, in the Move software has shown that most of the anticlines of the region are asymmetric due to the operation of detachment horizons. The results of the analyses indicate that the Shamshak Formation has more potential for developing detachment surfaces than the Chamanbide Formation. The reason for this detachment surface is due to thickness and mineralogy of the Shemshak Formation. On the other hand, by using geometric relationships, the depth of detachments was calculated for the main folds. In most of the detachments, this depth was calculated at lower levels of the Shemshak Formation. Manuscript profile -

There are many differences between these two types in many languages particularly from grammatical and lexical patterns that double the significance and necessity of separately studying these two. Based on this, the article reviews and analyzes words that are usually applied in conversation of Farsi speakers and are never or rarely used in written Farsi; and based on Boy’s view (2007) they are the result of word creation processes but not word formation. Following Boy view, under review data were categorized and reviewed based on the kind of word formation processes like shortening, combination, innovation, comparison, loaning, metaphorical expansion and phrasal conversion into four categories of Noun, Verb, Adjective and Adverb. The findings show that Shortening have the highest frequency (32.58 %) and phrasal conversion and combination have the lowest frequency (5.62 and 4.49 % respectively) in word formation.

Mankind has nourished many grate dreams and thoughts and just these great desires have caused his flourishing and elevation ‚ and where his dreams and desires cannot be practicable‚ he realized them with makind legends and mythical characters. One of these wonderful dreams which mankind has brought in to being, is everlastingness or immortality that has been reflected either in nations legends‚ fables and mythical works ‚ such as Gilgamesh ‚ Achilles, invulnerability of Isfandyar , or in religious narratives like Khezr. The dream of everlastingness made the mankind find a way to realize it. The human’s masterpieces throughout the history reflected this dream in an artistic language. Mawlānā’s Mathnavi is one of these masterpieces, where Mawlānā being inspired with Quran and the prophetic sentences, believes that love is the base of being, and due to the essence common to both God and mankind, i.e. the Divine Spirit breathed in mankind, he can become God-like and make himself eternal. The present article studies “the desire to eternity” in Mawlānā’s views, referring to his source of inspiration, and relying on some verses from Mathnavi and Divan-e Shams. Manuscript profile -

Symbolic tendency in the domain of contemporary literature is a result of the tyrannical situation and the dictator governments, added to the cautiousness and fear of media censorship, and stylistic transformations. All this can be furthermore combined with the delicate attempts taken for artistic enrichment; known as ‘ambiguity’, while it also intends to make the reader participate in the reading process and literary creativity in order to gain further enjoyment. Poets who are capable of independent thinking and are innovatively creative, protect the symbols; and save them from daily obscenity and even gradual death and decadence. Nima and the followers of his literary theory emphasized two words; that is “balance” and “naturalness” in using the symbols. They made an effort to utilize the repetitive, old and obsolete symbols within new concepts in order to enrich poems; in addition to enriching their own stylistic theory. Some of the symbols enjoy a particular entity and internal value, due to their history or flexibility in conveying multiple meanings and also being more influential in different artistic levels; therefore we can regard them as super-symbols. For gaining a proper semantic concept of a literary work demands an appropriate interpretation and understanding of such super-symbols. “Water”, “ wind”, “ night”, “ wall”, “ mirror” etc are some of such symbols; frequently used in contemporary poetry. The transformation of these super-symbols is the main question of the present article. Manuscript profile -

To do this, two monolingual Farsi Dictionaries have been selected based on their closeness to today's Spoken Farsi: “Sokhan” by Hasan Anvari (2003) and “Moaser e Emrooz” by Gholamhosein Sadri Afshar (2002). In this descriptive research, First, the compound words which were headwords in the dictionaries mentioned before were extracted (495 words in Anvari’s , and 605 words in Sadri Asher’s dictionaries). Then, these words have been classified into twenty five categories based on Tabatabaee (2010-2007). The analysis revealed that even those compounds formed by the productive and predictable word formation processes (e.g. noun + present verb stem( have been used as headwords in these dictionaries. It has been concluded that the concept of wordhoodness or wordness which refers to the changing of the constituents larger than words, e.g. sentence, phrase and etc. into a word is the main criterion for selecting compounds as the headwords. On the other hand, this research revealed that the lexicographers follows almost the same method in selecting the headwords. Manuscript profile -

Phenomenologists believe that the things identified do not reveal anything by themselves, but these are the humans who can understand things by looking through them and entering the soul of the world. Kant also said that we do not understand things as what they really are, but as what they appear to us. Our relationship with the world is not with the world as it really is, but with the world which is appeared to us. The author of Kashf al-Asrār who has a religious and a mystical approach towards the phenomena in Quran Verses, has been unconsciously influenced by the accepted worldviews (Weltanschauung) in each one of these two domain of thought, and in fact, by accepting the perspective of these religious or mystical approaches, the verses and the phenomena reflected in them are analyzed and interpreted according to these viewpoints. An example of these dual approaches is clearly visible in author’s attitude towards “God”. Therefore, this article aims at analyzing the author’s dual approach towards God, and the world views compatible with each domain of thought (religious and mystical) regarding this phenomenon in this work, by reviewing Maybudi’s discursive formations in the religious and mystical accounts in Kashf al-Asrār. A descriptive-analytical approach has been adopted in this research, and the results show that “Maybudi” applies different discursive formations in order to represent the things to be identified in accordance with the context of each discourse.

The mind tries to conceive and contemplate some intangible affairs for itself with the help of this fundamental construct. Hence, it is expected that by changing it, we will also see a change in thought-related macro-systems. Among these macrosystems are literary styles that have many factors involved in changing them. This article tries to answer the question of how the change of conceptual metaphors in time has an effect on the change of literary styles through analytical-descriptive method. To answer it, we trace the conceptual metaphors related to the body, which include the words "hand, eye, heart and head", in a selection of poems by Farrokhi Sistani, Anvari and Hafez. By analyzing the obtained information, we conclude that conceptual metaphors have undergone significant changes over time that are in line with the evolution of literary styles and are variables affecting the evolution of styles.

Government establishment is to adjust communal behavior of humans in a political affair in an acceptable way, to reduce possible threats from it and to increase the occurance of benefit, joy, and pleasure. Accordingly, the three ideal types of political consciousness-metaphysics, physics, and information- form three eras. The present article studies the process of theoretical and practical politics as its negative and positive aspects, and introduces the theory of chance studying crises and transitions. It discusses what different types of government establishment are. Is any regularity in them when the history of political philosophy is involved? What is the realization of government establishment in three eras of consciousness? The purpose here is to offer government establishment in an unbiased theory, which can move from its state as a negative constituent in the era of information to cover all the area of political thought.

Contemporary social sciences, due to the dominance of background-based approaches (in Sociology and Political Sciences) and quantity-based approaches (in Economics), didn’t give due attention to the analysis of institution variable status in forming social, economic and political phenomena. This article, first, attempts to introduce the institutional perspective in social and political analysis, and then introduces the internal reformations and varieties of this approach. The second purpose of this article is to show that historical institutionalism as a kind of neo- Institutionalism can develop an appropriate framework in integrating the Institutionalism and background-based approaches in political analysis, due to its dynamic viewpoint on the category of institutional change. According to this view, although different forms of institutions should be seen as independent variables in forming the social and political actors’ behaviors, these institutions are developed phenomena in the context of social and political historical disputes.

After years criminologists have found that certain locations effect on crime. So in recent years researches about the interaction between the physical environment of cities and social ills and crime has become increasingly important. Theft is one of the most important types of crime and delinquency. There are a variety of different forms of theft at the community level. Method:This study, Identifying and Spatial-temporal Analysis of urban Crime Hotspots, have been conducted in Semnan. Geographical information system and SPSS software are used in this study to do spatial and temporal analyze. In this study some crimes have been studied as a sample that took place in legal limit of Semnan city in range of 1394/1/1 until 1394/29/12. Then after preparing a database of theft and using statistical and graphical tests, crime hotspots have been identified and analyzed in a spatial way in Semnan city. This is a descriptive and analytical research and data is provided by library and statistical information and field observations. Findings and results:The results showed that the urban crime hotspots of Semnan are in the Imam street. With more details this area extends from Imam square to Mazandaran crossroad. These hotspots also lay in Semnan market. This market is in the crowded and bustling part of city and has mostly commercial function and unsuitable physical structure. It is cleared that in terms of time, the highest rate of theft in Semnan city had occurred in warm months of year as well as the initial days of the week. The results showed that most of thefts had occurred in a time between 9 A.M until 13 P.M. Manuscript profile -

Therefore, spatial analysis of this index is one of the basic necessities to understand the geographical changes of societies that must be carefully examined. The purpose of this article, which is applied in terms of research, is to investigate the use of ICT indicators in the cities of Khuzestan province according to the extent to which they have development indicators. The technique of collecting statistics and information in this article is using documentary and library methods and studying the official publications of the country. The statistical population of the study is 24 cities of Khuzestan province and the indicators studied in this research are 18 information technology indicators and also 31 indicators to determine the levels of their development. In this study, due to development inequalities between the cities of the province, first the cities were divided into three groups based on the indicators of development: privileged, semi-privileged and deprived. To determine the amount of digital divide between cities in each group based on the degree of ICT indicators, the PROMTEHEE technique was used. The AHP method was used to weight the indicators used in the grading. The research results show that Ahvaz and Haftkol counties have the highest and lowest levels of development indicators, respectively, and Izeh, Shadegan and Indika counties have the highest counties and Abadan, Ramhormoz and Bavi counties are the most deprived in terms of ICT indicators among other counties.

The fault detection structures are developed and they not only detected subsystem faults but also corrected faults introduced in the data processing system. Concurrent parity values techniques are very useful in detecting numerical error in the data processing operations, where a single fault can propagate to many output faults. Parity values are the most effective tools used to detect faults occurring in the code stream. In this paper, we present a methodology for redundant systems that allows to detect faults. Checkpointing is the typical technique to tolerate such faults. This paper presents a checkpointing approach to operate on encoded data. The advantage of this method is that it is able to achieve very low overhead according to the specific characteristic of an application. The numerical results of the multiple checkpointing technique confirm that the technique is more efficient and reliable by not only distributing the process of checkpointing over groups of processors. This technique has been shown to improve both the reliability of the computation and the performance of the checkpointing. Manuscript profile -

In the proposed method, some algorithms with low computational for generation, embedding and detection of security ID are designed. The collected data packets by the nodes are marked using security ID. In the proposed method, header is used to mark the packets. Since the nature of the sensor networks is cooperative, using the head of the packets is proposed for authentication. Also using the marked head can prevent from sending and receiving fake data in the other nodes. Simulations have been performed in environments with imposing unrealistic data and having a probability from 1% to 10%. Comparing the proposed method with other methods shows that the proposed method in term of security, reducing traffic and increasing network lifetime is more effective. Manuscript profile -

90 - Computing Semantic Similarity of Documents Based on Semantic Tensors
Navid Bahrami Amir H. Jadidinejad Mojdeh NazariExploiting semantic content of texts due to its wide range of applications such as finding related documents to a query, document classification and computing semantic similarity of documents has always been an important and challenging issue in Natural Language Process MoreExploiting semantic content of texts due to its wide range of applications such as finding related documents to a query, document classification and computing semantic similarity of documents has always been an important and challenging issue in Natural Language Processing. In this paper, using Wikipedia corpus and organizing it by three-dimensional tensor structure, a novel corpus-based approach for computing semantic similarity of texts is proposed. For this purpose, first the semantic vector of available words in documents are obtained from the vector space derived from available words in Wikipedia articles, then the semantic vector of documents is formed according to their words vector. Consequently, measuring the semantic similarity of documents can be done by comparing their semantic vectors. The vector space of the corpus of Wikipedia will cause the curse of dimensionality challenge because of the existence of the high-dimension vectors. Usually vectors in high-dimension space are very similar to each other; in this way, it would be meaningless and vain to identify the most appropriate semantic vector for the words. Therefore, the proposed approach tries to improve the effect of the curse of dimensionality by reducing the vector space dimensions through random indexing. Moreover, the random indexing makes significant improvement in memory consumption of the proposed approach by reducing the vector space dimensions. The addressing capability of synonymous and polysemous words in the proposed approach will be feasible by means of the structured co-occurrence through random indexing. Manuscript profile -

So it will probably be with the IoT and their use of data and attendant location privacy concerns. It must be recognized that management and control of information privacy may not be sufficient according to traditional user and public preferences. Society may need to balance the benefits of increased capabilities and efficiencies of the IoT against a possibly inevitably increased visibility into everyday business processes and personal activities. Much as people have come to accept increased sharing of personal information on the Web in exchange for better shopping experiences and other advantages, they may be willing to accept increased prevalence and reduced privacy of information. Because information is a large component of IoT information, and concerns about its privacy are critical to widespread adoption and confidence, privacy issues must be effectively addressed. The purpose of this paper is which looks at five phases of information flow, involving sensing, identification, storage, processing, and sharing of this information in technical, social, and legal contexts, in the IoT and three areas of privacy controls that may be considered to manage those flows, will be helpful to practitioners and researchers when evaluating the issues involved as the technology advances.

This requires an efficient algorithm to place the relevant webpages at first ranks. Regarding information retrieval, it is highly important to design a ranking algorithm to provide the results pertaining to user’s query due to the great deal of information on the World Wide Web. In this paper, a ranking method is proposed with a hybrid approach, which considers the content and connections of pages. The proposed model is a smart surfer that passes or hops from the current page to one of the externally linked pages with respect to their content. A probability, which is obtained using the learning automata along with content and links to pages, is used to select a webpage to hop. For a transition to another page, the content of pages linked to it are used. As the surfer moves about the pages, the PageRank score of a page is recursively calculated. Two standard datasets named TD2003 and TD2004 were used to evaluate and investigate the proposed method. They are the subsets of dataset LETOR3. The results indicated the superior performance of the proposed approach over other methods introduced in this area. Manuscript profile -

From computational viewpoint, the Farsi language is one of the less-studied and less-resourced languages, and suffers from the lack of high quality language processing tools. This problem emphasizes the necessity of developing Farsi text processing systems. As an element of EP research, we present a semantic approach to extract profile of person entities from Farsi Web documents. Our approach includes three major components: (i) pre-processing, (ii) semantic analysis and (iii) attribute extraction. First, our system takes as input the raw text, and annotates the text using existing pre-processing tools. In semantic analysis stage, we analyze the pre-processed text syntactically and semantically and enrich the local processed information with semantic information obtained from a distant knowledge base. We then use a semantic rule-based approach to extract the related information of the persons in question. We show the effectiveness of our approach by testing it on a small Farsi corpus. The experimental results are encouraging and show that the proposed method outperforms baseline methods. Manuscript profile -

It is to note that most effective non-contact measurement techniques can include the structured light patterns, provided in the surface of object for the purpose of acquiring its 3D depth. The traditional structured light pattern can now be known as the fringe pattern. In this study, the conventional approaches, realized in the fringe pattern analysis with applications to 3D imaging such as wavelet and Fourier transform are efficiently investigated. In addition to the frequency estimation algorithm in most of these approaches, additional unwrapping algorithm is needed to extract the phase, coherently. Considering problems regarding phase unwrapping of fringe algorithm surveyed in the literatures, a state-of-the-art approach is here organized to be proposed. In the aforementioned proposed approach, the key characteristics of the same conventional algorithms such as the frequency estimation and the Itoh algorithm are synchronously realized. At the end, the results carried out through the simulation programs have revealed that the proposed approach is able to extract image phase of simulated fringe patterns and correspondingly realistic patterns with high quality. Another advantage of this investigated approach is considered as its real-time application, while a significant part of operations might be executed in parallel. Manuscript profile -

On MoreNowadays, routers are the main backbone of computer networks specifically the Internet. Moreover, the need for high-performance and high-speed routers has become a fundamental issue due to significant growth of information exchange through the Internet and intranets. On the other hand, flexibility and configurability behind the open-source routers has extended their usage via the networks. Furthermore, after assigning the last remaining IPv4 address block in 2011, development and improvement of IPv6-enabled routers especially the open-sources has become one of the first priorities for network programmers and researchers. In IPv6 because of its 128-bits address space compared to 32-bits in IPv4, much more space and time are required to be stored and searched that might cause a speed bottleneck in lookup of routing tables. Therefore, in this paper, Bird as an example of existing open source router which supports both IPv4 and IPv6 addresses is selected and Bloom-Bird (our improved version of Bird) is proposed which uses an extra stage for its IP lookups using Bloom filter to accelerate IP lookup mechanism. Based on the best of our knowledge this is the first application of Bloom filter on Bird software router. Moreover, false positive errors are handled in an acceptable rate because Bloom-Bird scales its Bloom filter capacity. The Bloom-Bird using real-world IP prefixes and huge number of inserted prefixes into its internal FIB (Forwarding Information Base), shows up to 61% and 56% speedup for IPv4 and IPv6 lookups over standard Bird, respectively. Moreover, using manually generated prefix sets in the best case, up to 93% speedup is gained. Manuscript profile -

However, during the IT implementation process, decision-making, adaptation degree, and IT performance are often inferior to the anticipation. The assimilation of technology can be defined by the extent to which the use of Information technology spreads across organizational processes and becomes routinized in activities. Capabilities of information technology play crucial role in an ever-changing environment and are considered as one of the most important sources for enterprises while enterprises should acquire some effective capabilities so that they can effectively deploy and utilize information technology. The purpose of this investigation is to represent a model to measure absorbency of information technology in small and medium-sized enterprises. To do so, dimensions of the "absorbency of information technology" was determined through exploratory factor analysis in a survey research and confirmatory factor analysis was used to confirm model validity. Findings show that three dimensions are related to absorbency of information technology including the capability for innovative technology, Inside-Out IT capability and IT management capability, among which the capability for innovative technology has the highest correlation with the concept of absorbency of information technology.

MoreThe prior relation extraction approaches were relation-specific and supervised, yielding new instances of relations known a priori. While effective, this model is not applicable in case when the number of relations is high or where the relations are not known a priori. Open Information Extraction (OIE) is a relation-independent extraction paradigm designed to extract relations directly from massive and heterogeneous corpora such as Web. One of the main challenges for an Open IE system is estimating the probability that its extracted relation is correct. A confidence measure shows that how an extracted relation is a correct instance of a relation among entities. This paper proposes a new method of confidence estimation for OIE called Relation Confidence Estimator for Open Information Extraction (RCE-OIE). It investigates the incorporation of some proposed features in assigning confidence metric using logistic regression. These features consider diverse lexical, syntactic and semantic knowledge and also some extraction properties such as number of distinct documents from which extractions are drawn, number of relation arguments and their types. We implemented proposed confidence measure on the Open IE systems’ extractions and examined how it affects the performance of results. Evaluations show that incorporation of designed features is promising and the accuracy of our method is higher than the base methods while keeping almost the same performance as them. We also demonstrate how semantic information such as coherence measures can be used in feature-based confidence estimation of Open Relation Extraction (ORE) to further improve the performance.

In the last decade, advances in Deep Neural Networks (DNNs) have led to surprising improvements in many applications of ML. The result has been a paradigm shift in the community toward revisiting previous ideas and applications in this new framework. Ideas from IT are no exception. One of the ideas which is being revisited by many researchers in this new era, is Information Bottleneck (IB); a formulation of information extraction based on IT. The IB is promising in both analyzing and improving DNNs. The goal of this survey is to review the IB concept and demonstrate its applications in deep learning. The information theoretic nature of IB, makes it also a good candidate in showing the more general concept of how IT can be used in ML. Two important concepts are highlighted in this narrative on the subject, i) the concise and universal view that IT provides on seemingly unrelated methods of ML, demonstrated by explaining how IB relates to minimal sufficient statistics, stochastic gradient descent, and variational auto-encoders, and ii) the common technical mistakes and problems caused by applying ideas from IT, which is discussed by a careful study of some recent methods suffering from them.

In this paper, a knowledge-based representation model for text documents is introduced. The system works by integrating structured knowledge in the core components of the system. Semantic, lexical, syntactical and structural features are identified by the pre-processing module. The enrichment module is introduced to identify contextually similar concepts and concept maps for improving the representation. The information content of documents and the enriched contents are fused (merged) into the graphical structure of semantic network to form a unified and comprehensive representation of documents. The 20Newsgroup and Reuters-21578 dataset are used for evaluation. The evaluation results suggest that the proposed method exhibits a high level of accuracy, recall and precision. The results also indicate that even when a small portion of information content is available, the proposed method performs well in standard text mining applications. Manuscript profile -

In this paper, a new and general version of the Gaussian channel in presence of two-sided state information correlated to the channel input and noise is considered. Determining a general achievable rate for the channel and obtaining the capacity in a non-limiting case, we try to analyze and solve the Gaussian version of the Cover-Chiang theorem mathematically and information-theoretically. Our capacity theorem, while including all previous theorems as its special cases, explains situations that can not be analyzed by them; for example, the effect of the correlation between the side information and the channel input on the capacity of the channel that can not be analyzed with Costa’s “writing on dirty paper" theorem. Meanwhile, we try to exemplify the concept of “cognition" of the transmitter or the receiver on a variable (here, the channel noise) with the information-theoretic concept of “side information" correlated to that variable and known at the transmitter or at the receiver. According to our theorem, the channel capacity is an increasing function of the mutual information of the side information and the channel noise. Manuscript profile -

In t MoreNowadays, Security Information and Event Management (SIEM) is very important in software. SIEM stores and monitors events in software and unauthorized access to logs can prompt different security threats such as information leakage and violation of confidentiality. In this paper, a novel method is suggested for secured and integrated access control in the SIEM. First, the key points where the SIEM accesses the information within the software is specified and integrated policies for access control are developed in them. Accordingly, the threats entered into the access control module embedded in this system are carefully detected. By applying the proposed method, it is possible to provide the secured and integrated access control module for SIEM as well as the security of the access control module significantly increases in these systems. The method is implemented in the three stages of the requirements analysis for the establishment of a secure SIEM system, secure architectural design, and secure coding. The access control module is designed to create a secured SIEM and the test tool module is designed for evaluating the access control module vulnerabilities. Also, to evaluate the proposed method, the dataset is considered with ten thousand records, and the accuracy is calculated. The outcomes show the accuracy of the proposed method is significantly improved. The results of this paper can be used for designing an integrated and secured access control system in SIEM systems.

Providing a comprehensive overview of all aspects of the model. The purpose of this article is to provide insights into the state of the art of digital transformation in the last years and suggest ways for future research. This analysis is like a mapping of the subject literature into categories, so that with the help of a number of experts the evolutionary trends can be identified and further researched. In this way, with a deeper understanding of the subject, we have attempted to identify existing gaps. The findings suggest that organizations of all sizes must adapt their business strategy to the realities of digital transformation. This will largely lead to changing business processes as well as managing operations in a new and more intelligent tool-based way. Based on this research, organizations will evolve not just on their own, but on the whole value chain, and this will clearly change the way they produce and deliver value. Organizations can develop their digital ecosystem by creating and developing innovation centers and using open innovation strategy, and as a result, link their digital business to a value chain. Also in this article, we have identified the main categories and subcategories by examining the sources and using the grounded theory approach, as well as determining the relationship between them. Finally, we completed the work by identifying the digital transformation model as the central phenomenon of research. Manuscript profile -

ITC is critical significant to build enterprise agility and promote organizational performance. However, IT capability is always treated as the causal factor already existing and there are few studies on how IT capability is created and evaluated. Appropriate evaluation is necessary for an organization to measure, manage and improve enterprise ITC. This research aims to identify and map the dimensions of an organization's ITC. Using a mixed research method, this paper comprises two sections. The qualitative section adopts a systematic literature review (SLR) approach to identify the dimensions of ITC. The quantitative section employs factor analysis to validate identified ITC dimensions and their indicators in an attempt to develop a more precise model for ITC evaluation. The proposed ITC model includes IT management, IT human resources, IT infrastructure, and implementation of IT solutions dimensions as well as the 25 related indicators. Drawing on the results of this paper, organizations can engage in evaluation and improve/create essential ITCs based on the evaluation results. Manuscript profile -

The reliability model comprises of three units i,e Spinning machine (S), Weaving machine (W), Colouring and Finishing machine(Cf). The working principal of the model starts with spinning machine (S) where in unit S is in operative state while as weaving machine, Colouring and Finishing machine are in ideal state. Complete failure of system is observed when all three units of system i.e. S,W and Cf are in down state. Repairperson is always available to carry out the repair activities in the system in which first priority in repair is given to Colouring and Finishing machine followed by Spinning and weaving machine. The proposed model attempts to maximize the reliability of a real life system. Reliability measures such as Mean Sojourn time, Mean time to system failure, Profit analysis of system are examined to define the performance of the reliability characteristics. For concluding the study of such model, different stochastic measures are analyzed in steady state using regenerative point technique. The tables are prepared for arbitrary values of the parameters to show the performance of some important reliability measures and to check the efficiency of the model under such situations.

Tortuosity is a feature that is able to show the characteristics of normal or abnormal blood vessels. This study aims to analyze the performance of the CAD-RH system based on feature extraction tortuosity of retinal blood vessels. This study uses a segmentation method based on clustering self-organizing maps (SOM) combined with feature extraction, feature selection, and the ensemble Adaptive Boosting (AdaBoost) classification algorithm. Feature extraction was performed using fractal analysis with the box-counting method, lacunarity with the gliding box method, and invariant moment. Feature selection is done by using the information gain method, to rank all the features that are produced, furthermore, it is selected by referring to the gain value. The best system performance is generated in the number of clusters 2 with fractal dimension, lacunarity with box size 22-29, and invariant moment M1 and M3. Performance in these conditions is able to provide 84% sensitivity, 88% specificity, 7.0 likelihood ratio positive (LR+), and 86% area under the curve (AUC). This model is also better than a number of ensemble algorithms, such as bagging and random forest. Referring to these results, it can be concluded that the use of this model can be an alternative to CAD-RH, where the resulting performance is in a good category. Manuscript profile -

In the literature, this phenomenon is expressed as opinion formation and has a wide range of applications, including predicting social movements, predicting political voting results, and marketing. The interactions could be face-to-face or via online social networks. The social opinion phases are categorized into consensus, majority, and non-majority. In this research, we study phase transitions due to interactions between connected people with various noise levels using agent-based modeling and a computational social science approach. Two essential factors affect opinion formations: the opinion formation model and the network topology. We assumed the social impact model of opinion formation, a discrete binary opinion model, appropriate for both face-to-face and online interactions for opinion formation. For the network topology, scale-free networks have been widely used in many studies to model real social networks, while recent studies have revealed that most social networks fit log-normal distributions, which we considered in this study. Therefore, the main contribution of this study is to consider the log-normal distribution network topology in phase transitions in the social impact model of opinion formation. The results reveal that two parameters affect the phase transition: noise level and segregation. A non-majority phase happens in equilibrium in high enough noise level, regardless of the network topology, and a majority phase happens in equilibrium in lower noise levels. However, the segregation, which depends on the network topology, affects opinion groups’ population. A comparison with the scale-free network topology shows that in the scale-free network, which have a more segregated topology, resistance of segregated opinion groups against opinion change causes a slightly different phase transition at low noise levels. EI (External-Internal) index has been used to measure segregations, which is based on the difference between between-group (External) links and within-group (Internal) links. Manuscript profile -

The Tirgan Formation was measured with a total thickness of 237 and 192 meters in Navia and Ghezelghan sections respectively and was represented by thick and sometimes medium bedded, grey and weathered cream colored limestones in two localities. In Navia section, the Tirgan Formation conformably overlies the Zard – Shurijeh Formation with sharp lithological changes. However, as a result of being located in the core of an anticline, this boundary is not determined in Ghezelghan section. The Tirgan Formation disconformably underlies the Abderaz Formation in Navia section while conformably underlies the Sarcheshme Formation at Ghezelghan section. As a result of biostratigraphical investigations, 58 species belonging to 68 genera of foraminifera were identified in the Tirgan Formation. Based on benthic foraminifera two biozones were determined as follows: 1. Palorbitolina lenticularis Taxon Range Zone 2. Novalesia producta – Orbitolina spp. assemblage zone According to the determined biozones and fossils associations, the age of the Tirgan Formation is Barremian – Early Aptian in both sections. The comparison of the Tirgan Formation, in two-mentioned sections, shows some differences. In terms of biostratigraphy, there is not any significant distinctions, except for thickness difference in biozones. Manuscript profile -

The interval numbers are derived by aggregating the crisp weights that are calculated by exploiting the existing weighting methods. The proposed method, calculates an interval number as the overall relevancy of each document with the given query. We have discussed three approaches for ranking the interval relevancy numbers. In the experiments we have conducted on Cranfield and Medline datasets, we have studied the effects of weight normalization, use of variations of term and document frequency and have shown that appropriate selection of basic term weighting methods in conjunction with their aggregation into an interval number would considerably improve the information retrieval performance. Through appropriate selection of basic weighting methods we have reached the MAP of 0.43323 and 0.54580 on the datasets, respectively. Obtained results show that he proposed method, outperforms the use of any single basic weighting method and other existing complicated weighting methods. Manuscript profile -

Due to the rapid growth of population, increasing energy demand, and limited energy resources, one of the basic measures to achieve sustainable development in countries, is optimization and reform of energy consumption structures. Given that the home sector is one of the main sectors of energy consumption, one of the effective approaches in reducing and managing household energy expenditures is to use ICT capabilities. In this regard, in this study, the effect of ICT expansion on energy consumption of urban households in Iran using the Panel Data method and GLS model during the period 2008-2015 and in the form of provincial data has been analyzed. The results indicate that in some models, a significant reducing effect of ICT on energy expenditure was observed. However, in most of the estimated models, there is no significant reducing effect of ICT on household energy expenditure. It seems that the main reasons for this are the subsidy structure governing energy prices, the low share of energy in total household consumption expenditures, the lack of proper consumption culture.

However, after the Renaissance, intense oppositions to formality began and the sovereignty of will has grown steadily, and this transformation and attitude has also become more objective in the legal system of Iran after the constitutional revolution, but after a while a lot of criticism, philosophically or legally, appeared regarding it and its severity and intensity has been reduced. In Iran's law, by setting Article 10 of the Civil Code as well as Article 957, the legislator has shown tendency to the principle of sovereignty of will, but this does not mean that we interpret the traditional and jurisprudential texts according to modern interpretations.

By studying the timing and mechanism of deformation and compare it with different regions of a fold thrust belt, it is possible to gain a better understanding the history of the structural evolution. The timing and development of deformation in the Zagros folded belt is one of the widely studied topics and the general belief is that collision of two plates of central Iran and Arabian began in Miocene, and gradually developed from the northeast to the southwest. According to the present study, the timing of folding of the Jaril anticline in the northern of Dezful embayment is estimated to be end of Middle miocene (Serravalian). The results of the present study indicated that the onset folding of the Jarik anticline in this area coincides with the deposition of the lower Aghajari Formation. Manuscript profile -

The main thickness of the studied section consists of evaporite deposits. Based on the field studies, petrography and XRD data, these evaporite deposits are mostly consist of gypsum, anhydrite, dolomite, calcite and quartz. Field and petrographic study, imply that the gypsum and anhydrite are present in three types: primary (type one), secondary (type two) and Tertiary (type three) and dolomites are related to very early diagenesis. The primary evaporites which are laminated and layered gypsum, were deposited in a subaqueous shallow environment (salina) due to solar evaporation. Secondary evaporites with nodular texture and enterolithic and chicken-wire structures, were formed during epigenetic and shallow burial diagenesis (coastal sabkha). Moreover, tertiary evaporites with alabasterian, porphyroblastic and satin spar textures are related to burial and uplifting of primary and secondary evaporites in telogenesis and phreatic meteoric conditions. The abundance of evaporite minerals as well as other evidences of this sediments in the Saran section indicates a warm and dry climatic conditions during deposition of the Kond Formation. Due to the layered nature of evaporites of the Kond Formation in the Saran section and their association with shallow marine facies and the presence of significant thickness of volcano-clastic deposits of the Karaj Formation below these deposits, Eocene seawater and also migration of ions from older tuffs is suggested as the source of ions required for the deposition of these evaporite units.

BI as a discipline is made up of several related activities, including data mining, online analytical processing, querying and reporting. Companies use BI to improve decision making, cut costs and identify new business opportunities. BI is more than just corporate reporting and more than a set of tools to coax data out of enterprise systems. With today’s BI tools, business folks can jump in and start analyzing data themselves, rather than wait for IT to run complex reports. Evaluating the effectiveness of Business intelligence system is vital to our understanding of the value and efficacy of management actions and investments. This research aims to explain and clarify the inter-relationships and the interaction effects among business intelligence systems maturity and other relevant factors such as information access quality and information content quality. We developed a model of business intelligence systems maturity based on the outcomes of previous researches and semi-structured interviews with experts in information technology. To examine the model a descriptive survey was applied. The survey sample population consisted of 100 randomly taken managers and IT managers who apply Business intelligence system in their companies, according to a cluster random sampling skim. An important part of the results revealed business intelligence systems maturity relates directly with information quality and use of information in business process. Manuscript profile -

In all technologically advanced countries, patent applications are publicly disclosed after 18 month from the filing date regardless of whether a patent has been or will be granted. Therefore, one needs to ask why disclosing information contained in patent applications is important at national level. How the society benefits from it? In this paper, we examine patent disclosure as a primary function of patent system. Then we investigate both de jure and de facto patent disclosure in Iran. Based on a recent research in the field, we argue that although Iranian legislators have consciously promoted patent disclosure, the practice is well outside international accepted norms and standards. We finally argue that in absence of corrective measures, the Iranian patent system continued to be ineffective and fails to play its due role in the country's science and technology development.

To re MoreInformation is the driving force for today's knowledge economy and information systems are tools for information application. While numerous benefits of information systems are proven, substantial risk of failure is still burdening implementation of such projects. To reduce the risk, attention must be paid to critical success factors. After reviewing the relevant literature, success factors for the transfer of information system technologies are identified. Using such factors, this research evaluates and prioritizes them in the context of Pars Khodro and Saipa Auto Companies, as well as Sazeh Gostar Parts Co. in Iran. A questionnaire was administered among 32 IS/IT experts and consultants in those firms. The chosen firms have had experience with the transfer of information system technologies like MES and ERP. The proposed classification in this research divides critical success factors into three broad categories: organizational factors, tactical factors, and technical factors. Consistent with others' findings in the area of information systems, this research finds that the managerial, organizational and tactical factors dominate the technical aspect, and special attention to the former reduces the risk of failure associated with the implementation of information systems. As one of the primary objectives of this research, it has been found that the most important critical success factors in each category are: 1) Among organizational factors, the support and commitment of top management, and clear understanding of business objectives and organizational requirements are the most important; 2) Within tactical factors, effective project management and competent teams are critical; and 3) Among technical factors, adequate training, extensive organizational participation, and retention of skilled employees are important.

With increasing tendency in using Web-based technologies for ameliorating job performance, Information Technology systems act as a vital section in business operations. In the current research, results of organizational development pertaining to critical factors of web-based knowledge management effective transmission are concerned. Infusion and diffusion processes are evaluated by acceptance of effectiveness of web-based knowledge management technology in organizational systems. Incepted acceptance and transmission of Information Technology tools in the accepting system business processes, will not necessarily guarantee the change in taste of users and designers. It becomes obvious only at a time when IT systems cause changes. Once this technology is deployed, a need for acquiring and measuring integration arises; this claims that a need for diffusion level as a source of change exists. Each of mentioned processes, i.e. Infusion and Diffusion, are influenced by a set of constituents. In this study, we use experimental models of infusion and diffusion for web-based Knowledge Management technology. The change source in technology transmission is considered in this research. Also, some applicable advices are suggested for effective transmission of web-based knowledge management technology in organizations.

There has been some confusion as to the relationship between KM and BI. BI mainly focuses on explicit knowledge, but KM encompasses both tacit and explicit knowledge. Both of them promote learning, decision- making and understanding. KM influences BI through organizational knowledge creation, knowledge transfer and learning. Therefore, this paper defines BI as a part of KM by evaluating importance of their integration. As this relationship improves right decision-making in organizations and their performance because of the rise and fall of the economic environment, enterprises need to adjust their policies and strategies rapidly in order to respond to sophistication of competitors, customers and suppliers. Information is known as the main key for enterprises so integrating Business Intelligence and Knowledge management are used not only for saving suitable information for enterprise but also for improving performance and process of activities in organizations.

This matter seems incomplete without paying attention to the applicability of the mentioned concepts. Hence, in this article, the basic assumptions of knowledge management and its relation to information technology are investigated from both theoretical and practical perspectives. The formation, definitions, literature, processes, and all the issues related to the knowledge management will be presented. In addition, it is mentioned that in spite of the close relationship between information technology and knowledge management, it is not possible to substitute technology for human knowledge. Finally, having reviewed some principles and obstacles to knowledge management, the researchers propose innovative ways in order to carry out knowledge management programs via information technology in Iran.

In fact, the main purpose of confidentiality agreements MoreIPRs owners, especially inventors, from the creation of idea up to its commercialization are often faced with disclosure of confidential information delivered to third parties during license agreement negotiations. In fact, the main purpose of confidentiality agreements is to protect different types of IPRs including know-how, trade secrets, etc. with a view to prepare the background for proper and effective supervision and management of their exploitation. The use of non-disclosure agreements in high-tech sector, specifically for computer and internet companies is a common in license agreement negotiations. On the other hand, researchers and inventors in knowledge-based companies may be faced with challenges like disclosure of confidential information in the process of acquiring IPRs protection. The important point is the ignorance of many idea owners and inventors as to how such agreements are concluded. When delivering confidential information, non-disclosure agreement covers merely this information and is concluded for its protection before license agreement is concluded or during license agreement negotiations. Signing and entering into such agreements, without knowledge of laws and their characteristics, may cause dangerous and heavy obligations for parties. In this paper, with an analytic-descriptive approach, we define non-disclosure agreement, its necessity, function, types and common terms and conditions. The results of this paper indicate the necessity of delivering accurate and efficient information to IPRs owners regarding entering into confidentiality agreements and the need to modify the current legal structure in order to protect their rights.

Currently we face the problems of asymmetry of information and asymmetry of information in different sections can set grounds for increasing corruption and damage to resistant economy. Measures to reduce the asymmetry are necessary to be thought of. One of the strategies is using knowledge management systems. However, according to limitations appeared during the sanctions, successful implementation of these systems has faced some barriers. Therefore, identification of factors that lead to successful implementation of knowledge management systems can be very influential because, whether during the sanctions or after them, attempts should continue to be made in the field of establishing resistant economy. Hence, by reviewing various studies conducted in the field of knowledge management, 15 variables have been identified. In order to check the hypothesis, a researcher-made questionnaire was used whose validity was calculated by Cronbach’s Alpha to be 0.81. In order to test research questions, SPSS Version 18, MATLAB, TOPSIS and one-sample T-test were used. Research results showed that all variables were identified to be influencing the success of knowledge management systems in resistant economy. Information technology infrastructures had the highest importance and periodical evaluations had the least importance from among the 15 variables. Manuscript profile -

First, the use of information and communication technology has led to the replacement of new technologies with old technologies and thus improves the efficiency of electricity consumption and, consequently, reduces their consumption (substitution effect). Second, installation, commissioning and operation of new information and communication technology equipment will increase demand for electricity (income effect). Therefore, the overall effect of information and communication technology on electricity consumption is a function of one of the effects. Accordingly, in this paper, the relationship between the use of information and communication technology and electricity consumption in a group of selected developing countries during the period of 1994-2015 was studied. For this purpose, the dynamic panel model with the PMG approach was used. The results presented in two separate models show that increasing the use of information and communication technology will increase per capita consumption of electricity energy in both short and long term in selected developing countries. Also, the results show that in selected developing countries, economic growth is the cause of electricity consumption, while there is a one-way causality relationship between information and communication technology and electricity consumption and economic growth.

It is based on privacy standards, integrity and availability of information assets. In the present report, not only a model for evaluating the information security maturity in the headquarters of one of the oil industry companies is developed, but also the defect analysis and implementation of the existing organization are initially carried out in accordance with the requirements of ISO 27000. By defining the indicators of evaluation and measurement of these indicators in the organization, its maturity is estimated in this security standard. Different models are presented to identify the weaknesses and security powers of a particular organization. The goal is to identify a gap between theory and practice that can be approximated by the process-oriented approach. The puberty model introduced and used in this project, provides a starting point for implementing security, a public view of security, and a framework for prioritizing operations. This model of information security maturity has 5 phases. (The maturity model is information security as a tool for assessing the ability of organizations to meet security goals, that is, confidentiality, integrity and availability, and prevent attacks and access to the mission of the organization in spite of attacks and accidents)??. This model defines a process that has all aspects of security management, measurement, and control. The results of the evaluation show that the organizations which have security investments ahead of time have to understand the needs for high-level management of information security in the organization, and in addition to the actions taken in the field of physical environment, network and personal computers, controls access and encryption have been made to identify the necessary training and culture.

Achieving the goals of sustainable development in the field of architecture requires attention to all environmental, economic, and social aspects. Studies have shown that sustainable architecture, especially later-related movements, which utilize modern technologies in design and construction fields, are more suited to such goals. In this regard, computer-based design technologies, as effective instruments, played a significant role in achieving sustainability goals. This research investigates the amount of the effects of building information modeling (BIM) applications in different stages of the design process on achieving sustainability goals. The research method is descriptive-analytic. So indicators related to the use of BIM in sustainability achievement were collected through the library sources and case studies that contain sustainable buildings, which were designed using BIM applications. Then, by performing a hierarchical analysis based on the criteria derived from theoretical foundations, the authors concluded that the major BIM effects in achieving sustainability are due to the possibility of using dynamic analysis in the early stages of the design process, particularly the conceptual design stage as well as the establishment of effective interactions between engineers and other stakeholders.

Commercialization is a prerequisite for achieving competitive advantages and entering today's businesses in various fields of information technology. The purpose of this study is to present an IT commercialization model in online businesses. In order to conduct the research, the qualitative research approach and based on the data method of the foundation using semi-structured interviews with experts in the field of information technology commercialization have been used. The sample size included a total of 12 people by judgmental sampling method until theoretical saturation was achieved. Data encoding was performed using Max Kyoda software. Findings showed that commercialization of information technology in online businesses with 10 components including (economic factors, legal issues, structure, factors related to marketing, management factors, factors affecting business, political issues, cultural prerequisites , Business environment, technology management) were explained. It is suggested that in order to achieve successful commercialization in online tourism businesses, infrastructure indicators should be constantly monitored. Prioritize cultural support for the organization's commercialization activities, change and encourage consumer attitudes, and create a positive attitude toward information technology. Due to the lack of research in the field of commercialization of knowledge-based products, it is suggested to study the model of commercialization of knowledge-based products with emphasis on information technology.

In our country, children are facing with various problems and this problems comes from different reasons (economic, social, cultural, etc.). Street children and children who are vulnerable to harm, mainly for economic reasons, who work on the streets and, in fact, spend most of their time in unsafe and risky streets and, as a result, are more exposed to these children, especially girls. There are various risks. Understanding the status, problems and harm of these children, gathering statistics, information and resources about them, getting acquainted with the causes and factors causing these injuries and increasing them, is the first step in helping these children and trying to make the necessary changes in their lives. It means to benefit from their rights. The lack of information and their distribution in relation to children exposed to harm in general and working and street children are in particular a barrier to planning and organizing activities to relieve them of harm. Designing a database of street children and children can be promising in this field, and it is necessary to transfer it through the database to future generations. Manuscript profile -

The MoreThe treatise On Generation and Corruption is one of the treatises on nature which Aristotle wrote in about 347-335 BC. This treatise consists of two books: in the first one, Aristotle introduces generation and corruption as two basic properties of sublunary bodies. The other properties of sublunary bodies include transformation, growth and shrinking, contact, action and interaction, and mixing, which are completely distinct from each other in Aristotle’s view. He rejects absolute generation and corruption and criticizes Empedocles’ theory of equating them with transformation. The second book is mainly devoted to a profound investigation of the four primary elements (water, earth, air, and fire), their nature, and the quality of their changing into each other. Aristotle believes that these elements come into being in a cyclical fashion and none is prior to the other. Ibn Sina divided the existents of the world into four groups of intellects or angels, angelic souls, spherical bodies, and the bodies of the world of generation and corruption. He matched the ontological distinction between immaterial beings and those beings which are coupled with matter and are subject to generation and corruption with the astronomical distinction between the spheres and the sublunary world. Ibn Sina followed Aristotle in this regard. In this paper, the authors analyze the concept of generation and corruption in bodies from the viewpoints of Aristotle and Ibn Sina. They also examine the extent of Aristotle’s influence over Ibn Sina concerning generation and corruption, as well as the latter’s innovations in this regard. Manuscript profile -

The present paper reports on the results of a critical study of Jurjani’s reasoning regarding the simplicity of the derivative. In his view, whenever the derivative is assumed to consist of “shayin lahu …”, in case of attaining the concept of “shay”, interference of general accident in differentia occurs. However, in case of attaining the extension of “shay”, the transformation of the possible proposition through the necessary happens. In the first case, the differentia fails to be a differentia, and in the second case the direction of possibility is removed from the world of reality. In order to explain the quality of the transformation, a solution has been presented which analyzes the concept of portion and the role of limitation and determination in the predicate. Here, the writers, in spite of considering this argument to be perfect, clarify that the given reason for demonstrating the simplicity of the derivative is inefficient and is only capable of deriving the concept or referent of “shay” from the truth of the derivative.

Scale-invariant feature transform (SIFT) is one of the most common matching methods previously used in the remote sensing image registration. The defects of SIFT are the large number of mismatches and high execution time due to the high dimensions of classical SIFT descriptor. These drawbacks reduce the efficiency of the SIFT algorithm. To enhance the performance of the remote sensing image registration, this paper proposes an approach consisting of three different steps. At first, the keypoints of both reference and second images are extracted using SIFT algorithm. Then, to increase the speed of the algorithm and accuracy of the matching, the SIFT descriptor with the vector length of 64 is used for keypoints description. Finally, a new method has been proposed for the image matching. The proposed matching method is based on calculating the distances of keypoints and their transformed points. Simulation results of applying the proposed method to some standard databases demonstrated the superiority of this approach compared with some other existing methods, according to the root mean square error (RMSE), precision and running time criteria.

How a firm decides to apply its working choices passes on data to market members, among these its rivals. The real options exercise technique is an essential data transmission component. Pariahs find out about the absence of activity by contenders and can fuse it into their guesses about the rivals' sort. This endeavor to gain from contenders’ activities will specifically influence the harmony exercise methodologies. In this paper we expand a model to consider finite horizon real option games under incomplete information with various parameters. In incomplete information games firms’ actions express significant information about profitability to contestants. The encapsulation of this information proposed original blocks in models with strategic interactions. This is because of circularity where best exercise decisions are based on previous decisions taken, which at a given time are quiet to be mentioned because about the dynamic programming principle. We expand an extended version of the Least Squares Monte Carlo algorithm to confront these results. The model can aid in understanding the relation between strategic optionality and information besides how this influences the best decision policy and its value results. We find the informational feature is of great significance for firms’ best decision policy and optimization of project values Manuscript profile -

Therefore, we try to quantify those relations in this study. So, to structural investigate the relationships among the elements, a model is proposed that presents a novel comprehensive insight to the lean transformation process. This study proposed an analytic modeling approach in the lean enterprise transformation to identify the weights of the elements. The goal is to operationalize the highly qualitative relationships among the lean transformation components. In this paper 32 effective factors in lean enterprise transformation, identified as "sub sub criterion" were grouped into eight categories classified as "sub criterion". These eight sub criteria classified through 3 criteria in the higher level which are “organizational asset development”, “quick adaptation to markets and competitive superiority acquisition” and “supply and distribution network optimization These three criteria were proposed as the major criteria involved in "delivery value maximizing", and ultimately, the value maximizing recognized as the main target of the lean transformation in companies. Fuzzy DEMATEL technique and fuzzy analytic network process modeling are used to determine the relationships and the relative weights of each component and then with fuzzy VIKOR method, 25 identified solutions related to conceptual model were ranked for implementing the lean transformation which regard the organizational purposes and the weights of the end level parameters of the conceptual model in a proposal framework. The present evaluating lean enterprise transformation is a comprehensive model that can be applied to different production industries. This model also was investigated in automative parts industry.

With human society development, urban areas and Metropolises have not been safe from destructive effects and consequences of disasters. In addition to intensity and extent of disasters, vulnerability of societies has remarkable dependence on proper urban infrastructures, strong structures, preventive programs and appropriate preparation in emergency-related organizations. Occurrence of an onset disaster like earthquake, usually leads to secondary damages in urban areas; they happen for an obvious reason and have specific outcomes. Identification of all significant reasons and consequences results in creating a vulnerability map for urban wards which could be a useful basis for preventive programs. On the other side, one of the most effective and efficient approaches to create preparedness and response plan disaster management organizations, is designing a relief chain with proper logistic modules and devoting responsibilities to authorities, based on data achieved from damage estimation studies. Hence, in this paper, a sequential approach is used to apply geographic information system and eliciate experts' knowledge of urban areas so as to create both damage estimation and vulnerability maps; These information. In turn, help designing disaster management cycle, specifically, Preventive, preparedness and response programs for an urban area. In order to create a better perceptive of the proposed approach, Tehran municipality district (1) is used as a real case study and its vulnerability to a hypothetical earthquake is estimated to create disaster management program.

Many scholars in strategic management field have tried to provide multiple approaches or styles for strategy formation in the organizations. An effective way to identify strategy formation approach is to investigate how successful organizations are directed and lead. In this way, the reliable methods of strategy formation can be achieved by investigation of the organizations. This paper presents the result of a wide study on strategy formation approaches in Iranian organizations. Firstly, using taxonomical statistic method, five successful companies among 29 companies from various industries were selected as a result of their first ranking in their industrial groups during 2011-2013. To do this, six performance indices including asset returns, profit margin, human productivity, market share and sale rate, and profit growth rate were employed. Through the identification of the companies, their revolution trends were examined and the most important strategies leading to their success were determined. Finally, using a questionnaire and a sample of 150 top and middle managers of the surveyed organizations, their strategy formation approaches were identified. Entrepreneurial approach in strategy formation was more effective than formal approach or strategic planning, strategic venturing approach, and strategic learning approach. In some organizations, a combination of two approaches, namely strategic planning approach and entrepreneurial approach were utilized to formulate their strategies. Hence, it is obvious that among investigated companies, this is entrepreneurial approach that can be considered as reliable to formulate successful strategies. Manuscript profile -

One of the most strategic approaches to decrease the problems of Tehran as a centralized capital city is decentralization. In fact, decentralization not only leads to progress, growth, and social development for other cities of the country, but also enhances the capital administration. In this research we discuss that information technology management can lead to decentralization of Tehran with the minimum challenges and costs. Also, it can help the capital administration. Hence, in this paper, with interdisciplinary approach we first investigate the attractions of Tehran, and then apply an analytical hierarchy process (AHP) method to rank the attractions. Finally, we highlight the factors which can reduce the number of visits to Tehran by developing information technology. In fact, we propose the use of information technology to provide these attractions available in the other cities. Pairwise comparisons of attribute preferences are determined by experts from public and private organizations. The research findings shows that information technology not only has a significant effect on traffic reduction and optimum administration of Tehran city but also cause a much fare assignment of Tehran facilities to the other cities in the country.

On the other h&, the need for continuous organizational change in a dynamic and changing environment today is the presence of transformational leaders. Due to the increasing attention given to leadership in creating change and organizational performance around the world, this study tries to examine the relationship between transformational leadership and organizational performance by mediating the strategic orientations of entrepreneurship and market orientation, from the perspective of senior executives of small & medium enterprises In the food industry of Kerman Province in the first six months of 2017. The data gathering tool was questionnaire & data analysis was done by using LISREL and PLS softwares. The results show that transformational leadership has significant effect on both market and entrepreneurial tendencies; but evidence suggests a lack of support for the mediating role of market orientation in the relationship between transformational leadership & marketing capabilities; and confirming the indirect impact of transformational leadership on developing marketing capabilities & performance improvement merely through the entrepreneurship orientation in our studied businesses.

The assessment of IT department is critical to understand how the department contributes to organizational and strategic goals. Because IT department performs many tasks that cannot simply be measured by monetary units, evaluation methods that solely rely on financial measures are not adequate. The objective of this study is to construct an approach based on the fuzzy analytic hierarchy process (FAHP) and balanced scorecard (BSC) for evaluating an IT department in the company studied. The BSC concept is applied to define the hierarchy with four major perspectives (i.e. financial, customer, internal business process, and learning and growth), and performance indicators are selected for each perspective. A fuzzy AHP (FAHP) approach is then proposed in order to tolerate vagueness and ambiguity of information. A FAHP information system is finally constructed to facilitate the solving process. The results provide guidance to IT departments in the Industry Case Study regarding strategies for improving department performance. The constructed information system is suggested to be a good tool for solving other multiple-criteria decision-making problems. Manuscript profile -

In these so called multiple input multiple output (MIMO) communication systems, the algorithms used for detection of transmitted symbols are based on perfect channel state information (CSI) at the receiver side. The optimum detection approach in the sense of symbol error rate (SER) is Maximum likelihood (ML) detector. However, in the case of imperfect channel knowledge, the performance of this type of detection method degrades and symbol error rate (SER) increases. In this manuscript, we have briefly addressed the effect of imperfect channel knowledge on the performance of MIMO communication systems. Then, an analytical approach is proposed to cope with the destructive effect of CSI uncertainty on the ML detection algorithm and the performance of our proposed method is verified via computer simulations.

The main idea is based on information block mapping into two carrying units: a transmit symbol unit that is chosen from constellation members and second unit is the number of active antenna that shows the position of transmit antenna. The use of active antenna position as an extra source of transmit data increases the bandwidth efficiency. Also it doesn't have inter-antenna interference (IAI) and inter-channel interference (ICI) and it's caused to decrease the complexity in receiver side. So SM is a competitor in multiple antenna systems like V-BLAST and space-time coding. More recently generalized spatial modulation (GSM) is presented that use some active antennas instead an active antenna. When the symbol is sent from multiple antennas, it'll get a diversity gain. In this paper we show that by using different channel coding in GSM we can improve bit error rate (BER) without decrease in bandwidth efficiency between 15-40 percent. Manuscript profile -

This information can be used in the behavior analysis of the person. Low quality of the recorded surveillance images, noisy data and cluttered backgrounds are some of the difficulties in this task. In the existing methods, histogram of orientation gradient (HOG) is used to estimate the orientation. The local properties of HOG is a weakness for orientation estimation. The edge surrounding the object, namely contour, is a useful information for orientation estimation. In this paper we present a general form of a contour. This hyper contour helps us to find the best contour which is matched to image of the person in a hierarchical fashion. These contours generated from a human 3D model. The matched contour as a high-level feature is combined with the low-level feature such as HOG, and considered as the final feature. The proposed feature is a linear combination of several types of contours with respect to different regions of the body. To show the impact of the proposed feature on orientation estimation, a support vector machine is trained on a hybrid feature space and then is evaluated on VIPeR dataset. The experimental results show that the accuracy of the orientation estimation is improved about 4% by using the extended feature. Manuscript profile -

Since the efficiency of most data mining algorithms decreases with increasing data dimensions, analysis of the data has become one of the most important issues recently. Online stream feature selection is an effective approach which aims at removing those of redundant features and keeping relevant ones, leads to reduce the size of the data and improve the accuracy of the online data mining methods. There are several critical issues for online stream feature selection methods including: unavailability of the entire feature set before starting the algorithm, scalability, stability, classification accuracy, and size of selected feature set. So far, existing methods have only been able to address a few numbers of these issues simultaneously. To this end, in this paper, we present an online feature selection method called MMIOSFS that provides a better tradeoff between these challenges using Mutual Information. In the proposed method, first the feature set is mapped to a new feature using joint Random variables technique, then the mutual information of new feature with the class label is computed as the degree of relationship between the features set. The efficiency of the proposed method was compared to several online feature selection algorithms based on different categories. The results show that the proposed method usually achieves better tradeoff between the mentioned challenges. Manuscript profile -

Recordings of heart electrical activities by Electrocardiogram (ECG) are a safe method to detect abnormal arrhythmia in time and reduce cardiac failure in newborns. However, the non-invasive extraction of fetal ECG (fECG) from the maternal abdominal is quite challenging, since the fECG signals are often corrupted by some electrical noises from other sources such as: maternal heart activity, uterine contractions, and respiration, in addition to instrumental noises. Among such signals, the maternal heart signal (due to high amplitude) has the most disruptive effect and the fetal brain signal (due to low amplitude) has the least effect on distortion of the fetal heart signal. In this paper, a new method for extracting fECG signals from multichannel abdominal recordings is proposed. The proposed method uses Compressive Sensing (CS)to reduce the computational complexity and fast Independent Component Analysis (fICA) algorithm to estimate the sources. Also, for finding sparse representations of the acquired ECG signals, two dictionaries namely: discrete cosine transformation and discrete wavelet transform are deployed here. The proposed method is then implemented and its performance is tested using the well-known and publicly available database used in 2013 Physionet Challenge. The performance results are compared with that of the best performing existing methods. The results show that the proposed method based on CS and ICA outperforms the existing detection methods with a Mean Minimum Square Error (MMSE) of 171.65, and therefore can be used for non-invasive and reliable extraction fECG from abdominal recordings.

Much research has been conducted to analyze individual news articles, while most news events in the media are published in the form of several related articles. Event detection is the task of discovering and grouping documents that describe the same event. It also facilitates better navigation of users in news spaces by presenting an understandable structure of news events. With rapid and increasing growth of online news, the need for search engines to retrieve news events is felt more than ever. The main assumption of event detection is that the words associated with an event appear in the same time windows and similar documents. Accordingly, in this research, we propose a retrospective and feature-pivot method that clusters words into groups according to semantic and temporal features. We then use these words to produce a time frame and a human readable text description. The proposed method is evaluated on the All The News dataset, which consists of two hundred thousand articles from 15 news sources in 2016 and compared to other methods. The evaluation shows that the proposed method outperforms previous methods in terms of precision and recall. Manuscript profile -

This research was done with the aim of explaining the concept, examples and issues of child privacy in the family with emphasis on pandemic conditions. Method: The present research was done with descriptive-analytical method using library resources. Results: The Covid Pandemic highlights the need for new ways of thinking about data protection. This is especially true of child-related health research. Responsible use of children's information plays a key role in promoting children's health and guaranteeing their right to health and privacy. With the widespread outbreak of the coronavirus worldwide, governments have put protocols, such as quarantine, in place to reduce the prevalence of the virus. With children quarantined at home and social activities shut down, the home is no longer the only place to relax and socialize with family. With the limitation of children's daily activities to the home environment, the issue of respecting the child's privacy is becoming more and more important in various aspects. Conclusion: For many children, school, extracurricular classes, socializing with peers, fun, etc. are summarized at home. Concentrating children's activities at home does not mean that all aspects of a child's life are observable for parents; rather, it should be noted that the child still has privacy and all his/her rights in private solitude, physical privacy, information privacy, communication privacy and personal privacy are still protected.

Progress in the technology of mobile phones has recently resulted in the emergence of several popular services such as location-based social networks (LBSNs) and predicting the next Point of Interest (POI), which is an important task in these services. The gathered trajectory data in LBSNs include various contextual information such as geographical and temporal contextual information (GTCI) that play a crucial role in the next POI recommendations. Various methods, including collaborating filtering (CF) and recurrent neural networks, incorporated the contextual information of the user’ trajectory data to predict the next POIs. CF methods do not consider the effect of sequential data on modeling, while the next POI prediction problem is inherently a time sequence problem. Although recurrent models have been proposed for sequential data modeling, they have limitations such as similarly considering the effect of contextual information. Nonetheless, they have a separate impact as well. In the current study, a geographical temporal contextual information-extended attention gated recurrent unit (GTCI-EAGRU) architecture was proposed to separately consider the influence of geographical and temporal contextual information on the next POI recommendations. In this research, the GRU model was developed using three separate attention gates to consider the contextual information of the user trajectory data in the recurrent layer GTCI-EAGRU architecture, including timestamp, geographical, and temporal contextual attention gates. Inspired by the assumption of the matrix factorization method in CF approaches, a ranked list of POI recommendations was provided for each user. Moreover, a comprehensive evaluation was conducted by utilizing large-scale real-world datasets based on three LBSNs, including Gowalla, Brightkite, and Foursquare. The results revealed that the performance of GTCI-EAGRU was higher than that of competitive baseline methods in terms of Acc@10, on average, by 42.11% in three datasets. Manuscript profile -

Therefore, this research has been carried out with the aim of investigating the effective factors on strengthening the infrastructure of information systems. The current research is applied in terms of purpose and descriptive-exploratory in nature. The research community is the government organizations of the country, and 10 people were selected to form the expert panel from among the experts who have the qualifications. Among the employees, 250 people were selected as a statistical sample by simple random sampling. The research method is a combination of multi-criteria decision-making methods (hierarchical analysis process), structural equations and fuzzy inference system. After extracting the dimensions and factors from the literature and the background of the research, the ranking of the effective factors in the form of five dimensions and 15 components was done using the multi-criteria decision making method. The results showed that the legal infrastructure has established the highest correlation with the infrastructure of information systems. Also, among the dimensions, the technological infrastructure is the most important. The results of fuzzy inference also showed that the most favorable state for information subsystems is 0.698 according to the available facilities, and the optimal combination for this state is achieved when structural factors are 0.724, organizational factors are 0.58, governance factors are 0.569, social factors are 0.707, and educational factors are 0.468. Therefore, in order to strengthen the infrastructure of the country's information systems, it is suggested that the officials focus on strengthening and developing structures and supporting technological innovations in the first step.

Its upper and lower boundaries are comfortable with Gachsaran and Pabdeh formations. Three assemblage zones at the studied section were recognized based on benthic foraminifera and biostratigraphy study. Detected biozones reflect Oligocene (Rupelian and Chattian) and Miocene (Aquitanian) age for this studied deposits with 348 meters thickness. Assemblage zone 1, with Firozabad section and assemblage zone 2 with 3 other sections and assemblage zone 3 with Dill anticline are correlatable. Environmental parameters such as: salinity, light, nutrients, temperature and depth, have played a role concerning the distribution of foraminifera. Accordingly, the Asmari Formation deposited in a normal salinity to hyper salinity water, aphotic to euphotic and oligophy to eutrophy zones. Grain supported microfacies (O4, O5, B, L1, L2, L4, L5 and L7), support reservoir quality for the Asmari Formation in subsurface areas, next to the studies section. The carbonate grain association types of the study section are nanofer, rodalgal, foralgal and foramol. Manuscript profile -

Simply, determination of magnitude and direction of In-situ stress around wellbore is the first step of geomechanical studies and wellbore stability particularly. Preliminarily, because of importance of casing collapse problem in the Marun oilfield, the magnitude of in-situ stress is determined. The magnitude of vertical stress (Sv) was in range of 85 to 90 MPa. The minimum horizontal stress (Shmin) determined by some analytical methods. For estimating of maximum horizontal stress (SHmax) domain we used Anderson’s faulting theory and stress polygon. So the magnitude of SHmax was so close to Sv and the faulting regime shows normal/strike slip. Within Gachsaran Formation in depth of collapses because of salty lithology and high pore pressure, magnitude of In-situ stress is so close and it can be assume hydrostatic stress state.

The Azadegan reservoir contains paraffinic and paraffinic – naphthenic oils with an API of 30. The gas chromatograms reveal that the source rocks responsible for these oils contains mainly type II kerogen deposited in a reducing environment. According to these data the studied oils have a relatively high level of thermal maturity. Ratios of C35S/C34S, C29/C30, C31R/C30 Hopane and Pr/Ph, Ph/nC18 show that the studied oil derived from carbonate source rock; which is also evident form Pr/Ph Vs. DBT/Phen diagrams. Diagrams of (20R) C29/C27 vs. Pr/Ph as well as the ratios of C21+/C21-, Pr/P, TAR are consistent with abundance of algal organic matter. Presence of Tricyclic terpanes, higher ETR ratios and diagrams of δ13C vs. Pr/P introduce a Jurassic aged source rock for the studied oils. Based on biomarker and isotopic data it could be concluded that oils within the Azadegan reservoir are mainly derived from carbonate source rocks of Mid-Upper Jurassic which are deposited in paralic/open marine environment with a predominance of algal organic matter.

Subsequently, results from core and thin section studies compared with core porosity and permeability and petrophysical wireline logs, especially resistivity logs. Due to texture variation (mudstone to grainstone) and diagenetic events (dolomitization, dissolution, calcite and anhydrite cementation), porosity type and percentage changed in wide range in this formation. This study showed that resistivity logs could be used as an effective tool to distinct effective and ineffective-bearing zones. High permeability intervals have relatively high deep resistivity and high separation between deep and shallow resistivity logs, whereas non-reservoir intervals have low resistivity and very low separation between deep and shallow resistivity. Based on this study, studied carbonate interval of the Asmari Formation was divided into 13 zones. Using separation of deep and shallow resistivity logs, flow zones could be correlated throughout the studied field Manuscript profile -

This paper describes the process and workflow for data-acquisition and interpretation in a shale formation characterization program and demonstrates not only the benefits of acquiring specific data, but also highlights the uses of the data to aid the exploration decision process. The next purpose of this paper is to provide a research process that can be applied in similar geological settings. In the study process, we collected a complete set of information and samples from the field and presented a detailed case study, including laboratorial studies of formation samples and interpretation of the information. Available samples and information sources from Burgan Formation include drillhole cores. The minerals were defined by direct and indirect methods. Bulk XRD analyses performed on core samples showed presence of traces of clay minerals. For determination of the exact clay mineral type, clay minerals were extracted and treated by heat and ethylene glycol saturation. Treated samples were subjected to XRD analyses. Interpretation of the natural gamma spectrometry logs allowed the determination of the type and content of clay minerals. In a next step, in order to study the distribution of minerals types, SEM photomicrographs and Cation exchange capacity (CEC) of the samples were carried out. The results revealed that shale intervals of Burgan Formation are not expandable clays. The instability problem cannot be completely solved by drilling fluid design. The study shows, different approached methods reached the same results. Manuscript profile -

However, for MorePorosity parameter is an important reservoir property that can be obtained by studying the well core. However, all wells in a field do not have a core. Additionally, in some wells such as horizontal wells, measuring the well core is practically impossible. However, for almost all wells, log data is available. Usually these logs are used to estimate porosity. The porosity value obtained from this method is influenced by factors such as temperature, pressure, fluid type, and amount of hydrocarbons in shale formations. Thus it is slightly different from the exact value of porosity. Thus, estimates are prone to error and uncertainty. One of the best and yet most practical ways to reduce the amount of uncertainty in measurement is using various sources and data fusion techniques. The main benefit of these techniques is that they increase confidence and reduce risk and error in decision making. In this paper, in order to determine porosity values, data from four wells located in Azadegan oil field are used. First, multilayer neural network and multiple linear regressions are used to estimate the values and then the results of these techniques are compared with a data fusion method (Bayesian theory). To check if it would be possible to generalize these three methods on other data, the porosity parameter of another independent well in this field is also estimated by using these techniques. Number of input variables to estimate porosity in both the neural network and the multiple linear regressions methods is 7, and in the data fusion technique, a maximum of 7 input variables is used. Finally, by comparing the results of the three methods, it is concluded that the data fusion technique (Bayesian theory) is a considerably more accurate technique than multilayer neural network, and multiple linear regression, when it comes to porosity value estimation; Such that the results are correlated with the ground truth greater than 90%.

In this study, Kazhdumi, Gadvan, Garu and Sargelu Formations in Darquain Oilfield, in Abadan Plain, were analyzed by Rock-Eval 6 instrument. S2 vs. TOC plot revealed that kerogen type in this oilfield predominantly is of mixed of types II & III. Significant S2 Adsorption by matrix of Kazhdumi Formation in well numbers 1 and 2 (5.33-14.06 mg HC/gr rock) and Gadvan Formation in well numbers 2 and 3 (3.1-3.2 mg HC/gr rock) is due to low thermal maturity as well as low Gas-Oil Ratio factor. In Garu and Sargelu Formations amounts of adsorbed S2 by matrix are respectedly 0.82 and 0.84 mg HC/gr rock, that represent a medium thermal maturation and medium to high Gas-Oil Ratio factor. Quantity of TOClive in the Kazhdumi, Gadvan, Garu and Sargelu formations estimated to be in the range of 0.6-1.6, 0.2-1.9, 1.53 and 8.38 by weight percent respectively. This represents potential for the studied formations fair to excellent petroleum generation. Also the studied wells were modeled, by which the Ro of the source rocks were calculated according to their depth. Also transformation ratio of organic matter and the initial TOC is estimated. Transformation Ratio of Kerogen in studied formations ranges from 0.12 to 0.66. This is in accordance with estimated Easy Ro by PBM software (0.5-0.8). It can then be concluded that Kazhdumi Formation is in early oil window and already started to generate hydrocarbon. This is also verified by Tmax data. The Gas-Oil Ratio of Kazhdumi and Gadvan Formations is 0-1 indicating variable hydrocarbon generation. Also this factor for Garu and Sargelu is 0.58-1 indicates that they have more gas generation potential rather than oil generation potential. The inferences drawn from It can be inferenced from iso TOCoil and TOCgas maps led to the conclution that, in west and southwestern parts of the basin, the depth during deposition of mentioned formations was more in compare to other parts of Darquain.

In this study reservoir rock types were recognized according to lithology, rock fabric, geometry and amount of porosity. Therefore, 7 reservoir rock types were determined: - Anhydrite without reservoir quality, - limy– dolomite with mud dominated fabric without reservoir quality, - limy– dolomite with mud dominated fabric and an average reservoir quality, -limy– dolomite with mud dominated fabric and good reservoir quality, - dolomite with crystalline fabric and low reservoir quality, - limestone with grain dominated fabric with an average reservoir quality and - dolomite with crystaline fabric with a good reservoir quality. Based on petrophysical logs(Gamma ray, sonic, neutron & density), 5 reservoir units and 6 non – reservoir units were identified. Reservoir units are mainly formed of porous grain dominated limestone ,crystalline dolomite and mud dominated fabric dolomite, and non – reservoir units include anhydrite and limy dolomite without porosity. Petrophysical and petrographical studies indicate that moldic, intercrystaline and interparticle porosities are the most effective porosities in the reservoir units of this formation, whereas others like vuggy , fracture and intraparticle porosities have minor role in reservoir quality.

248 - Using information entropy theory and bayesian decision method to identify appropriate parameters for evaluating and discriminating oil facies (mansuri oil field, south of Iran)

These met MoreDue to subsurface heterogeneity and existing vagueness in geophysical interpretation, identifying and interpretation of facies in wellbores is always prone to uncertainty and risk. Nowadays several methods have developed for quantitative facies interpretation. These methods are generally divided into deterministic and stochastic categories. Deterministic methods, in spite of their simple modeling procedure, cannot expose the amount of error or accuracy of the model. On the other hand, stochastic methods, in addition to quantifying the error of the model, can provide the probability of the model’s accuracy in each point of the reservoir. The Bayesian approach is one of the stochastic methods that use conditional probabilities for modeling. This approach, as well as probabilistic modeling of hydrocarbon facies, quantitatively computes the effect of additional data in decreasing the error of the classification. Information entropy theory, by quantifying the intrinsic uncertainty in each model input parameter, can easily provide the selection of valuable parameters. The present study was carried out on one of the wells of Mansuri oil field, south of Iran. After generation of training data by using rock physics techniques and Gassmann’s relation, the value of each input parameter was identified by entropy analysis. Then, by use of Bayesian analysis and valuable parameters, oil facies classification and discrimination was implemented. The five optimum parameters were elastic impedance, compressional wave velocity, shear wave velocity, density and porosity .The amount of error in this method is approximated to be 11 percent. This investigation also showed that gamma ray parameter does not have a drastic positive effect on identification and discrimination procedure of oil facies, which has a good agreement with the results of entropy analysis .

Measurements obtained from well logs, containes some errors and uncertainty. This porosity is influenced by different factors, such as temperature, pressure, fluid type, clay content and the and amount of hydrocarbons. One of the best, and yet most practical ways to reduce the amount of uncertainty in porosity measurement is using various sources of data and data fusion techniques. Data fusion increase certainty and confidence and reduce risk and error in decision making. In this research, the porosity is estimated in 4 wells of Azadegan oil field, with data fusion method (Bayesian theory). To check the ability of generalization of the method, the porosity was also estimated in one other well of this field. A maximum of 7 input variables were used to estimate porosity in this new approach. The results showed that data fusion technique is more powerfull than traditional tecniques for porosity estimation. According to the results, this method has higher credibility than traditional techniques that show 0.7 to 0.8 regressions with log data but data fusion technique showed solidarity over 0.9 with log data.

The coordinates of such section are N: 29o 41' 59'', E: 51 o 32' 26''. The Asmari Formation deposits in this section are divided into 5 lithological units and consist of 460 m thin, medium, thick and massive bedded, gray and cream to gray limestone, slightly dolomitic with nodular and marly interbedded. By study of hyaline benthic foraminifera genera and non-foraminifera, and also recognition of some properties such as skeletal ingredient associations and sedimentary textures of thin sections, 14 microfacies have been introduced for the Asmari Formation. Gradual perpendicular changes of these microfacies represent that settling the Asmari Formation deposits took place in a homoclinal rapm. This homoclinal ramp consists of middle ramp and inner ramp, that are separated by shoal environment. Middle ramp is recognized by presence and dominition hyaline benthic foraminifera, coralline red algae and echinoids. The most significant skeletal debris of inner ramp are porcelainous foraminifera. To compare the thickness, age and sedimentary environment, zonal correlation of the Asmari Formation done in Deris section with three other sections (Naura anticline, Dill anticline and Dehloran) in the Zagros Basin. This correlation represent that the age of the Asmari Formation gets younger to the deeper parts of the foreland basin of the Zagros. Manuscript profile -

The study area is located in the Izeh zone, in the vicinity of Izeh city. Accordingly four outcrop sections (Halayjan, Kuh Shur, Kuh-e Bad and Gharibi Ha) have been sampled and investigated. Due to unique tectonical characteristic and lateral as well as spatial variations of the outcrops, different facies have been deposited across the Asmari Formation platform in the study area. Based on the sedimentary structures, texture, skeletal and non-skeletal grains, 11 microfacies have been recognized which have been deposited in three different sub environments including open marine, shoal and lagoon. Based on this reaserch, for the Asmari Formation, three independent depositional models have been considered during the Chattian, Aquitanian and Burdigalian. On the basis of the results of this study, during the Chattian, Aquitanian and Burdigalian the Asmari Formation has been deposited in a homoclinal ramp system. During the Burdigalian toward the NE of study area (Gharibi Ha section), the shallow water deposits are abruptly overlain by pelagic limestone. Therefore, during the Burdigalian toward the NE of study area, probably, the carbonate ramp has been changed to drowned carbonate platform. It is interpreted as the result of a regional tilting that started in the late of the Burdigalian. During the Chattian in the Gharibi Ha area, the base of the carbonate Asmari Formation transits into the marl-dominated Pabdeh Formation towards the Halayjan area which could be concerned as an analogue to investigate about the stratigraphic oil traps potential in the Izeh zone.

The total thickness of the Asmari Formation is 360 m and 260 m in the Lab-e Safid and Tang- e Lendeh sections, respectively and composed of thick, medium and thin bedded limestone. The correlation of recognized biozones in the studied regions with other regions in Zagros (Bangestan Anticline: tang-e Band, tang-e Nayab and Tang-e Bulfares, Parsi oil field, Kuh-Asmari and Khaviz Anticline: Tang-e Bibinarjes) indicates that Asmari Formatin in Tang-e Bibinarjes, Tang-e Band and, well no.4 of Lab-e Safid has deposited earlier than other regions. Four different sub environments were identified in the Asmari Formation based on microfacies analysis including tidal flat, lagoon, shoal, open marine. These depositional environments correspond to inner, middle and outer ramp. On the basis of deepening and shallowing patterns in the microfacies five and two third-order sequences have been recognized in the Lab-e Safid and Tang- e Lendeh sections, respectively. In order to study the changes of depositional environment of the Asmari Formation during the Oligocene-Miocene, the recognized sequences in this study have been correlated with those recognized in other parts of the Zagros basin.

Petrographic studies of 120 prepared thin sections of the upper parts of the Sarvak Formation in studied oilfield, Southwestern Iran, has resulted in definition of 6 microfacies sedimentary types. These data suggested that the middle Creataceous sediments in the studied area were predominantly deposited in two subenviornments of patch organic barrier and lagoon corresponding to inner and shallow a homoclinal ramp. In addition, using petrophysical logs in the studied well, 10 electrical facies were determined. By analyzing the data petrophysical in Geolog software, 10 electerical facies were optimized and then their number was reduced to six. According to good adaptation of optimized electerical facies with sedimentary microfacies, we would generalized obtained dresults to all parts of the Sarvak Formation. Study of porosity changes in the electrical diagrams such as CGR corrected Gamma, and sonic curves in mentioned well, indicated a significant reduction in facies porosity of 1 to 6. In addition, the results showed that the reservoir quality reductionin studied microfacies is corresponded to Bioclastic Rudist debris floatstone/ Rudstone, Benthic foraminifera Rudist debris wackestone / packstone, Benthic Foraminifera peloid Grainstone/Packstone, with High diversity benthic foraminifera wackestone / packstone, Peloid bioclastic wackestone /packstone with Low diversity benthic Foraminifera and Mudestone/Wackestone, respectively. In this study, we concluded that comparison and correlation sedimentary facies with electric microfacies provide an efficient method to study the quality of the hydrocarbon reservoir system that especially can be used in other wells with no core.

The first objective of this study MoreEstimation of formation water saturation (Sw) using log data is an important approach in the oil exploration and characterization of a hydrocarbon reservoir. Therefore, it seems that the proper prediction/simulation of Sw is essential. The first objective of this study was to develop a predictive model for Sw estimation based on hybrid cluster analysis with piecewise nonlinear regression, and after that, using the developed model, Sw was simulated by the Monte Carlo simulation (MCS). In order to achieve objectives of this study, a group of 909 data points was used for model construction and 302 data points were employed for assessment of model. The obtained results of MCS modeling indicated that this approach is capable of simulating Sw ranges with a good level of accuracy. The mean of simulated Sw by MCS was obtained as 0.28 m, while this value was achieved as 0.29 m for the measured one. Furthermore, a sensitivity analysis was also conducted to investigate the effects of model inputs on the output of the system. The analysis demonstrated that RHOB is the most influential parameter on Sw among all model inputs. It is noticeable that the proposed hybrid cluster analysis with piecewise nonlinear regression and MCS models should be utilized only in the studied area and the direct use of them in the other conditions is not recommended.

Young modulus with the unconfined compressive strength of rock, are two key parameters in the definition of intact rock. Elastic modulus represents the amount of rock rigidity and is known as the stress-strain chart slope. These parameters represent of rock strength to failure, are important parameters for the stability analysis of wellbore stability. According to the unavailability and cost of core data, and also attended to this fact that the data from the core are not continuous and not available at all points in the well, the uses of DSI logs is one of the best methods for calculating elastic modules. Using these logs, you can also study elastic moduli continuously in a well. In this study, elastic dynamic parameters were calculated using the DSI and density logs for the Dalan Formation. Attention to the fact that the calculated parameters using the velocity of the sound waves are of the type of dynamic parameters, these parameters were have converted to the static modules using appropriate empirical relationships. The rock strength Parameters were calculated using the experimental relationships commonly used in the oil industry to determine rock strength parameters. These parameters were calculated according to static elastic modulus as well as porosity and shale volume. Comparing the values of elastic modulus and rock strength parameters with porosity showed that porosity with elastic modulus and rock strength parameters has an inverse relationship, so that with increases the porosity, the elastic modulus and rock strength parameters have been reduced.

The Shahbazan Formation with 460 meters thick with mainly composed of dolomite along with interlayers of limestone, shale and anhydrite in the studied well. The lower boundary of this formation with the Pabdeh Formation is conformable and its upper boundary with the Asmari Formation is marked by an unconformity. The Asmari Formation with thickness of 140 meters mainly consists of limestone and shale with the interlayers of dolomite; its upper boundary to the Gachsaran Formation is conformable. Biostratigraphy studies documented a high diversity of shallow-water benthic and rare planktonic foraminiferas and led to the determining of one assemblage zone in the Shahbazan Formation (15 genera and 8 species) that indicates age of the Priabonain. Three assemblage zones also were recognized in the Asmari Formation (12 genera and 8 species) that, shows the age of the Asmari Formation from Mid-Rupelian to the Chattian, Aquitanian and Burdigalin. Based on biostratigraphy studies, the boundary between Shahbazan and Asmari formations and the position of an unconformity between them were determined. The facies analysis led to recognition of eight microfacies for the Shahbazan Formation which belong to three facies belts of inner (tidal flat and lagoon), middle and outer ramp, deposited on a ramp-type carbonate platform. Also four microfacies were recognized in the Asmari Formation which are related to the inner carbonate platform. Manuscript profile -

In order to construct an efficient and correct model of a hydrocarbon reservoir, identification of rock types is one of the essential parameters in reservoir modeling. and its consequences are found in the identification of rock types. The aim of this study is to compare different methods of determining rocky type and understanding the hydraulic flow unit distributions in order to assess the quality of reservoir of Razak Formation with sandstone carbonate lithology, marl and anhydrite to San Oligocene to lower Miocene. In this research, the experimental results of porosity, permeability and capillary pressure curves for 84 samples with porous microscopic sections Related to a 46-meter drill bit in one of the important fields of southeast of Iran were analyzed. The petrographic studies were conducted to investigate the changes of the features in the reservoir section with Razak formation and resulted in the identification of eight microfeatures( The MF1 packstone and Wackstone are at a depth of 2829 meters- The MF2 is the grinstone packstone at a depth of 2844 meters-the MF3 is the wackstone mudstone at a depth 2856 meters-the MF4 is the grinstone at a depth 2859meters –the MF5 is the mudstone wackstone are at a depth2848 meters – the MF6 mudstone at a depth of 2838 meters the MF7is the wackstone mudstone at a depth 2840 meters- The MF8 is a wackstone with sandstone depth of 2831) meters- in open Marin lagoon and fluvial clastic systems. In order to determine the rocky species and assess the flow units based on the core analysis results, four petrophysical classes were identified using the Lucia method. The petrophysical category number 1 has the best reservoir quality and the fourth category has the weakest reservoir quality. Also, the flow units were identified and separated using Amalufee and Lorenz's methods. Based on the Amalufee method, in the reservoir section of the Razak Formation, seven flow units have been identified, the sixth and seventh stream units were the best and one was the weakest reservoir segments among the seven units of the flow. Also, based on the analysis of capillary curves, six rocky species were distinguished, based on which the rocky type number five and six have the best quality. Also, using Geology software cross-sections, it was revealed that the main part of this section is sandstone with clay. The presence of gas in the formation causes cross-sectional deformation of samples to the northwest cross-platform. Finally, with the combination of various data, it was found the fossil formation in the study area has five types of rock in which the number 4 rock has the best quality of reservoir and rock number 5 has the largest reservoir and the unit number six is the best.

Cores studies from the one of wells of Gavarzin field is 183 m in thickness, which includes 1.30 m from the top of Pabdeh, 162.4 m from the Asmari Formation and 19.30 m from the base layers of Gachsaran. Asmari Formation includes alternation of limestone, calcite dolomitic, claystone and shale with green marl. Petrology and facies analysis of the sequence of these formations identified 12 microfacies, a carbonate ramp from deep-sea to sabkha environments and formed in a retrograded sequence. This ramp includes deep environments, open sea, patch reef, bio-, clastic-bars, lagoon and tidal environments, which confirms a changing environment due to rapid facies changes and deposition of evaporative sediments in Gachsaran as a restricted environment. Diagenesis processes are considered as the main factors in carbonate reservoir quality of Gavarzin field. The diagenesis history of the Asmari carbonates of the studied cores is summarized as A) marine phreatic diagenesis, bioturbation, micritization and cementation processes occurred. B) vadose zone diagenesis, where the crystallization, cementation, and dissolution occurred. C) burial diagenesis, comprises compression-induced, pressure dissolution and fracturing are common. The microfacies show a wide varieties of reservoir characteristics and therefore a heterogeneous reservoir has been formed. Micro-fractures, however have strongly influence on the reservoir quality in the section. The simultaneous presence of dissolved spaces and fractures in the reservoir the permeability greatly increased. The best reservoir quality in the Grainstone/Packston facies are coated grains with moldic porosity that were created by the leaching of Ooid-bearing Packston lithology during the diagenesis of atmospheric waters.

The aim of this study is to evaluate of mud loss of the Sarvak Formation (Cenomanian age) in Azadegan oil field which is known as the most important rich hydrocarbon reservoir in the Zagros region by providing the model in the environment of GS+ software. This formation consists of a thick sequence of limestone and clay limestone layers, which is divided into 7 zones based on petrophysical characteristics. For this purpose, available data such as drilling mud weight, pump pressure, mud loss, and related depths of 9 drilled wells were investigated. The results showed that despite of the operating factors including the weight of drilling mud and the pressure of the pumps were kept constant, the presence of fractures in the reservoir rocks causes to occur mud loss significantly in zone 3 while it is observed the lowest level of mud loss in zone7. Based on the results of mud lost data patterns, faults, sedimentary environments morphology (such as sedimentary channels) seem to play major roles in creating fractures or areas susceptible to mud loss. The difference in observed patterns of mud loss is more likely to confirm the relocation of channel status over the time in different parts of the reservoir. In general, the highest rate of mud loss was detected in the northern and southern edges while the lowest rate was happened in the middle part of the field. It is suggested to prevent mud loss hazards in this field, underbalanced drilling method should be used. Manuscript profile -

In this study, in order to assess the reservoir quality, from a petrographic study and porosity and permeability data, an important well in one of the oil fields of Abadan plain has been used. Based on microscopic studies, 13 microfacies have been identified in the form of Four facies tidal flat, lagoon, shoal and open marine for Sarvak Formation deposits in the studied oil field, indicating that the upper part of the Sarvak Formation is deposited in a homoclinal carbonate ramp. Among the identified diagenetic processes, dissolution, cementation, dolomitization, fracturing, compaction, neomorphism, micritization, bioturbation, pyritization, hematitization, phosphatization and silicification are mentioned. Diagenetic processes of Sarvak Formation occurred in three marine, meteoric and burial environments. Among the dissolution and fracturing diagenetic processes, the most important role has been in increasing the reservoir quality, and cementation and compaction have been the most important factors in reducing reservoir quality. Sequence stratigraphy studies identified third order sedimentary sequences of the age of Turonian, Late Cenomanian, and Middle Cenomanian, and studied the facies and diagenetic processes within its framework. Correlation of porosity and permeability data of the core showed that the reservoir quality in this formation was influenced by facies and diagenetic processes. So that the microfacies containing the rudist have the highest reservoir quality. Due to the diagenetic processes, sedimentary and porosity and permeability data, the facies shoal and open marine to the land have the best reservoir quality. Manuscript profile -

The formation with 239 m thickness consists of limestone and shale. Meanwhile, the Tarbur deposits overlie the Gurpi Formation and is covered by the Paleocene deposits. Seven and five microfacies and microtaphofacies were recognized based on the main components and sedimentological and taphonomical features, respectively. In addition, these microfacies and microtaphofacies were deposited in homonicnal carbonate ramp. From the viewpoint of vertical distribution and interpretation of microfacies and microtaphofacies, the Tarbur deposits were formed in the energetic environment (under the influence of the storm waves) in the study area. Therefore, communities of rudist are absent and the green algae (Dasycladales) are abundant in the study area. Concerning the high rate of detrital grain input and increasing of nutrients, the bryozoans were performed the encrusting more than other organisms. Manuscript profile -

Ebrahim MohammadiThe Qom Formation is the main reservoir and source rock of hydrocarbons in central Iran. Foraminifera are now central to our ability to date, correlate and analyse the sedimentary basins that are currently key to the economic wellbeing of the world. Morphogroup analysis MoreThe Qom Formation is the main reservoir and source rock of hydrocarbons in central Iran. Foraminifera are now central to our ability to date, correlate and analyse the sedimentary basins that are currently key to the economic wellbeing of the world. Morphogroup analysis, due to independence of species level taxonomy, as wel as permit to comparison of assemblages of differing ages, is a useful tool for ecological and palaeoecological interpretation. It is independent of species level taxonomy and is thus relatively elementary to translate from one worker to another. Foramniferal study of the Qom Formation in the Bujan (eastern Sirjan; with Rupelin-Chattian in age and 156 m thickness) and Varkan (southwestern Kashan; with Rupelin in age and 190 m thickness) sections resulted in identification of seven morphogroups. The morphogroups were distinguished according to test/shell morphology and architecture (general shape, mode of coiling, and arrangement and number of chambers), inferred life habitat either living on the surface of the sediments or within the sediments (epifaunal and infaunal), and feeding strategy (suspension-feeder, herbivore, etc.). Generaly, epifaunal morphogroups were dominated in both study sections. The morphogroup analyses showed variations in the percentage of the dominant morphotypes, suggesting fluctuations in the paleoecological conditions. In the Bujan section, the Rupelin deposits are dominated by calcareous porcelaneous morphogroups; while the Chattian deposits are dominated by hyaline morphogroups, which indicates the lower and upper parts were deposited in inner ramp (lagoonal environments) and middle ramps, respectively. This significant change through time reffers to gradual increasing of the basin depth, decreasing the light intensity, reducing the salinity and decreacing the nutrient level. De dominance of the hyaline morphogroups throughout of the Varkan section is indicative of the deposition in middle ramp environments with normal salinity under meso-photic to oligo-photic conditions.

Slope and direction of water level of Sirri-C ( Sivand) which is close to Sirri-D (Dena) , contain the same slope in both field, at the eastern border of field. The oil –water contact of Sirr- E, (Alvand) field has been constructed with good accuracy and fair probability in 1978. As a result, this modeling was confirm with actual result after full field development of this field on 2002. An entirely original study has been undertaken on residual oil of core, which permitted to characterize various zone as well as modern and fossil interfaces, and proved Hydrodynamic activity in the Mishrif reservoir in western part of Persian Gulf ( Sirri District). This study was carried out, with an approach to combined reservoir characterization , and revealed accuracy of results after full development of these fields. Manuscript profile -

This sect has experienced evolution in its life. The developments that took place with the formation of the Zaidi government in Tabarestan and Deylam. But this rule did not last for some reason and the Zaydi religion also disappeared with more distance and time and gave way to the Imams. The question is, what were the causes and factors of this change? The subject of this work is the study of the causes of this change of religion by referring to the original Zaydi texts and describing and analyzing them to explain the causes. It seems that besides various reasons, the most important reason for this is the heterogeneity of the intellectual and belief system, including: Imamate (Mahdism, the quality of choosing an Imam, the permission of the Imamate of several Imams at the same time) and other beliefs that arise from this, such as Bringing to Etzal and Hanafi jurisprudence, as well as important issues such as disbelief and practice of taqiyyah, moral corruption and their behavior, and leaving the Islamic world, provided the ground for the extinction of Zaydiyya in Tabarestan.

Mineralization occurs as lens-shaped orebody, hosted by limestone units of member of the Qom Formation usually crosscutting bedding of the host rocks. Three stages of mineralization occurred in the Madabad deposit. The first stage is characterized by calcite formation during syn-depositional to syn-diagenesis processes. The second stage is related to hydrothermal processes that are distinguished by formation of fine-grained and sugary crystals of massive stage-1 celestite, vein-veinlets of coarse-grained stage-2 celestite along with minor strontianite and barite, coarse-grained euhedral crystals of stage-3 celestite with vug infilling texture, and finally late-stage quartz and calcite vein-veinlets. Stage three includes supergene processes. Hydrothermal alteration includes dolomitization, calcitization and silicification. Celestite along with minor strontianite and barite are ore minerals, and calcite, dolomite, quartz and iron oxides-hydroxides are gangue minerals at Madabad. The ore minerals show vein-veinlets, vug infilling, brecciated and cataclastic textures. Microthermometric measurements of two-phase liquid-rich fluid inclusions hosted in celestite II indicate that salinities values range from 6 to 18 wt.% NaCl equiv. (avg. 10.6 wt.% NaCl equiv.). These inclusions have homogenization temperatures range from 248 to 365 °C, with an average of 278 °C. These data indicate a minimum trapping depth of 510 m for the Madabad deposit. Sr was originated from evaporate units within the marly parts of the Qom Formation and volcanic units of the Karaj Formation. Characteristics of the Madabad deposit are similar to epigenetic replacement celestite deposits. Manuscript profile -

The main question of this paper is whether the regime governing breach of confidentiality related to Chemical Weapons Convention is different from regulations related to common international law, and whether the contents of this Convention especially that related to breaches or alleged breaches of confidentiality (Para. 22, Section D of the Annexes) can exonerate the secretariat staff of the OPCW? The author hypothesizes that regulations of the Chemical Weapons Convention constitute a big part of the rules and principles of international law, and the confidentiality regime of the OPCW as well as liability resulting from breach of these regulations is a function of this regime.

One of the sustainable strategies to remove this environmental pollutant and convert it into hydrogen clean fuel is the use of a renewable energy source (photon) and synthesis of semiconducting nanoenergy materials. To this end, in the present project, a nanostructured magnetic semiconducting MgFe2O4 compound was synthesized and applied for the production of hydrogen fuel through photocatalytic splitting of an alkaline H2S solution. The empirical evidence revealed that the synthesized material has an appropriate potency to reduce proton and produce hydrogen. Furthermore, by the synthesis of CNT/MgFe2O4 magnetic nanocomposite, the boosting effect of carbon nanotube (CNT) on the activity of the aforementioned photocatalyst was examined. A significant promotion in hydrogen production was observed in the presence of CNT and justified in terms of increasing the photocatalyst surface area, retarding the electron-hole recombination process and enhancing the photon absorption. The rate of hydrogen evolution was 1284 µmole/h per 0.2 g photocatalyst, indicating that the synthesized nanocomposite material has a high ability to remove the pollutant and produce hydrogen fuel.

Then, while briefly introducing the space of computer security encounters in the form of ontology, for the first time, three perspectives in the study of patterns in this field have been identified and distinguished from each other. These three perspectives include the view of secure models, the view of security models, and the view of the framework and system to security models. The first and third perspectives are briefly explained and the second perspective is studied in detail from the perspective of the organization of patterns, including the five types of organization. The five types mentioned include software-based lifecycle organization, logical-level organization-based organization, threat-based classification-based organization, attack-based classification-based organization, and application-based organization. In this type of introduction of patterns, the audience acquires a comprehensive view of the discourse of computer security patterns and acquires the necessary knowledge to make better use of these patterns. Finally, the analysis and idea of this research is presented in the form of introducing a new type of organization in order to facilitate the proper use and addressing of patterns. In this idea, it is stated that the existing categories are mostly static and forward-looking and do not have the necessary dynamism and backwardness, and the idea of covering all stakeholders and security ontology can have this feature and, in addition, include agile patterns as well. .

In order to identify the microfacies and depositional conditions and diagenesis processes, 100 microscopic thin sections from one well of this reservoir in one of the Dezful embayment oil fields were evaluated. Porosity and permeability data were used to check reservoir quality. The petrographic study led to the identification of 9 microfacies belonging to the facies belts of lagoon, barier, middle ramp and outer ramp, which were deposited in the homoclinal ramp environment. The most important diagenesis processes identified in Ilam reservoir include cementation, dissolution, fracture, micriteization, stylolitization, and dolomitization. Based on the qualitative classification of the reservoir and Lucia's petrophysical diagrams, the lagoon facies and the middle ramp have an average reservoir status, and the carbonate barier facies and the outer ramp have a weak reservoir status. The reservoir quality of the lagoon and middle ramp facies is related to the existence of interconnected and channel porosities. Due to strong cementation and the presence of unrelated porosity such as mold porosity, the carbonate barier facies has low permeability and has a poor reservoir status. In general, the Ilam Formation in the studied field is in a weak state in terms of reservoir, which can be important in addition to the facies controllers in relation to the lack of expansion of fracture and dolomitization and the excessive expansion of cementation in these facies. Therefore, the Ilam Formation in the studied field has a weak reservoir performance due to diagenetic processes, despite having more shallow sequences than deep ones. Manuscript profile -

The Sarvak Formation with Late Albian-Early Turonian age constitute the important reservoir unit in the Abadan Plain region, SW Iran. This study investigates the application of Normalized Cumulative Gamma Deviation Log (NCGDC) to discriminate and correlate key sequence stratigraphic surfaces in six wells in a giant oil field in the Abadan Plain. To achieve this goal, identified key stratigraphic surfaces from core and thin sections were compared with interpretation of NCGDC method. From sequence stratigraphic point of view and based on the results from geological studies, the Sarvak Formation has been sub-divided into four third-order sequences which are described and interpreted. Two main disconformity surfaces, considered as sequence boundaries, are characterized by features of karstification, dissolution-collapse brecciation, and development of paleosol horizons. Generally, positive surfaces correspond to maximum flooding surfaces and negative surfaces occur at sequence boundary. Comparison of the results shows that, the identified sequence by NCGDC method can be effectively used for discrimination and correlation of sequences in different carbonate and siliciclastic reservoirs in the field scale.

The main aim of this study is to explore the relationship between paleoenvironment and paleoredox condition during deposition of the lower Devonian Jeirud Formation in the Garmabdar section, northeast of Tehran. The Jeirud Formation in the Garmabdar section, with a thickness of about 280 m, is composed of siliciclastics, carbonates, carbonate-siliciclastic hybrids and phosphorite deposits. Sedimentary facies analysis led to recognition of three siliciclastic facies associations related to estuarine environments under the influence of waves, shoreface and offshore and two carbonate facies associations related to intertidal and subtidal environments. Moreover, the geochemical paleoredox proxies (such as U/Th and V/Cr) also suggest prevailing anoxic conditions during deposition of black shales and phosphorites in the studied section. In overall, these results suggest that there is a good agreement between the depth of the depositional environment and anoxic conditions during deposition of black shales of the Jeirud Formation.

This sedimentary basin has been of interest for a long time because of hydrocarbon materials. Gavelinellids are the most abundant and dominant groups of benthic foraminifera in epicontinenal seas during Cretaceous period which belong to Rotaliinacean foraminifera. They have shown a wide biogeographical distribution and dispersion in many areas of Tethys. Their evolutionary trend during the Cretaceous time was success. The high concentration of marine sedimentary rocks and the absence of igneous activities in the Kope-Dagh sedimentary basinhave caused it to be considered the most suitable basin for the formation and accumulation of hydrocarbons after the Zagros sedimentary basin. This basin has suitable layers of carbonate rocks and porous sandstones to store hydrocarbon materials, also thick layers of shales in this basin can act as suitable source and cap rocks. In this research some genera and species from this family in Sanganeh and Aitamir Formations at five stratigraphic sections including Marave Tappeh, Takal kuh, Sheykh, Gadvecanlou and Kalat from point of biostratigraphical and paleoecological applications have been investigated. In this study, four biozones including Gavelinella flandrini-Gaudryina cf. praedividens assemblage zone, Berthelina intermedia assemblage zone, Berthelina cenomanica Assemblage Zone, Berthelina intermedia-Osangularia schloenbachi Assemblage Zone have been introduced. Based on the reported genera and species of the Gavellinidae family, it can be stated that the studied formations were deposited in the middle and outer part of the continental shelf to the upper part of the continental slope and in aerobic to semi-aerobic environments. The presence of more planktonic foraminifera than benthic foraminifera in the Aitamir Formation, the depth of the basin increases. Manuscript profile -

In research on the effects of information and communication technology, its effects on economic risk and political risk have not been considered so far. Therefore, this study has examined the effect of ICT development on economic and political risk for three selected groups of developed, developing, and OPEC countries in the period 2007- 2019. The panel data method was used to estimate the model. Based on the model estimation results for all sample countries, the deployment of information and communication technology reduces economic and political risk; But the results are different for each group. As the development of information and communication technology in selected OPEC members and developing countries increases economic risk; But in developed countries, it reduces economic risk. Also, in OPEC member countries, no significant relationship was found between ICT and political risk, and in selected developed and developing countries, ICT increases political risk.

T MoreSarvak Formation is one of the important carbonate reservoirs in Dezful Embayment. In order to evaluate the reservoir quality of this formation in one of the Dezful Embayment fields, multi-resolution graph-based method was used and compared with petrographic findings. The findings showed that the Sarvak formation in the studied field consists of 8 microfacies belonging to the sub-environments of the lagoon, carbonate bar, middle ramp and outer ramp, which were deposited in a homoclinal ramp environment. The main diagenesis processes affecting this reservoir include cementation, dissolution, fracture, stylolitization, and dolomitization. The results of multi-resolution graph-based analysis led to the identification of 3 electrofacies, EF1 electrofacies had the weakest reservoir parameters and EF3 facies had the best reservoir status. The majority of EF1 microfacies are grainstone microfacies and the majority of EF3 microfacies correspond to wackstone and packstone microfacies. Based on this, it seems that the lagoon sub-environment has a better reservoir condition than other sub-environments, especially the carbonate bar, and this is an important sign of the different performance of diagenesis processes in these sub-environments. In a vertical trend, the highest volume of hydrocarbon column is in the EF3 electrofacies and the lowest is EF1. In general, it can be stated that the use of multi-resolution graph-based analysis and comparison with petrographic findings is a suitable solution for accurate evaluation of the reservoir quality of carbonate reservoirs.

Nowadays, new researches show that primary education and the like have an undeniable role in reducing poverty and realizing economic and social development programs. Undoubtedly, a weak primary education system endangers the entire human capital development system. On the one hand, this system educates students who do not have the necessary preparation to enter secondary and higher education, and on the other hand, it delivers uneducated adults. More importantly, it will not train enough parents, workers and managers who have received real training to participate in development. It is at this stage that the students transform and develop their way of thinking and dealing with the learning problem. Therefore, the necessity of this research in order to reach the weaknesses and strengths of primary education in our country in comparison with Germany, which is a leading country in the European economy, which has seen an increasing growth in education in recent years, and to provide solutions to improve the weaknesses and strengthen the points. The strength of primary education in the country seemed necessary. The curriculum in Germany is decentralized and the books are written by other experts and approved by the Ministry of Education. The curriculum emphasizes more on the subjects than the book. Therefore, more flexibility is seen in the curriculum. In this country, German language, mathematics, experimental sciences, art and music are emphasized, which are somewhat close to Iranian subjects. Manuscript profile -

On the other hand, information retrieval has emerged as one of the major problems in the area of algorithms and computation. As graph-based information retrieval algorithms have shown to be efficient and effective, this paper aims to provide an analytical review of these algorithms and propose a categorization of them. Briefly speaking, graph-based information retrieval algorithms might be divided into three major classes: the first category includes those algorithms which use a graph representation of the corresponding dataset within the information retrieval process. The second category contains semantic retrieval algorithms which utilize the graph theory. The third category is associated with the application of the graph theory in the learning to rank problem. The set of reviewed research works is analyzed based on both the frequency as well as the publication time. As an interesting finding of this review is that the third category is a relatively hot research topic in which a limited number of recent research works are conducted. Manuscript profile -

Therefore, they still have a desire for traditional teaching, and some management and livelihood problems of the society have caused them to not follow the use of new methods in teaching and learning. In this regard, the requirements of the age of knowledge and information and the necessity of keeping pace with the developments and achievements of technology and human sciences have been gradually felt in our country, which is evidenced by the recent decisions of the government in the field of investment for the rapid expansion of Fava in the country. Also, in order to find a suitable answer to the type of questions mentioned above, education is trying to determine a charter to guide the reforms in the country's education, which emphasizes the use of Fawa as one of its pillars. Also, in recent years, extensive activities have been carried out in the field of using information technology and FAVA in the training of strengths and development. The current research was conducted with the aim of pathology of education based on information and communication technology in elementary school. In this research, firstly, the approaches, components and strategies of Fava-based education in elementary school courses were identified, and then the pathological examination of each of the components of the Fava-based curriculum in the elementary school was done to provide a practical model in this field.

The rock units in this area belongs to the Oligo-Miocene, which contain Lower Red, Qom and Upper Red formations. The Upper Red Formation in Ghezeljeh region has about 750 m thickness and mainly consists of brown to green marl intercalations with sandstones. In this area, the alternation of marl and sandstone sequences contain sandstone layers with thickness about 2 to 8 meters, which in two horizons, the copper-lead and zinc mineralization has occurred. Copper mineralization, in addition to being observed inside the sandstone unit. In the Ghezeljeh deposit, the host rocks of the copper ores, are gray sandstones and conglomerates which are intercalated with red and gray marl units. According to field and microscopic studies, the main ore mineral consist of pyrite, chalcocite, chalcopyrite, bornite, galena and sphalerite which associated with the secondary minerals such as serosite, malachite, azurite, covellite, smithzonite and goethite. The ore mineral textures consist of disseminate, framboidal pyrite, solution seams, interparticle cement, replacement and relict. Preliminary fieldwork studies in the Ghezeljeh region also show that organic matter including plant remains and diagenetic pyrite are the effective factors to concentrate and mineralization. It is considerable that the grade of lead, zinc and copper, in Ghezeljeh deposit are 6%, 3% and 1%, respectively. Generally, host rock, tectonic setting, sedimentary environment, mineralogy, texture, mineralization control factors all confirm that the studied mineralization has more similarities with Redbed type copper deposits.

The palynofloras include 22 species of spores (belonging to 18 genera), 15 species of pollen (attributed to 9 genera) and 28 species of dinoflagellate cysts (assigned to 15 genera). Based on the stratigraphic distribution of miospores, the Klukisporites variegatus-Araucariacites australis-Cerebropollenites macroverrucosus Assemblage Zone is recognized in the sequence examined, Presence of some index dinoflagellate species led to the identification of three successive biozones including, in an ascending order, Cribroperidinium crispum Total Range Zone (late Bajocian), Dichadogonyaulax sellwoodii Interval Zone (Bathonian – early Callovian) and Ctenidodinum continuum Interval Biozone (early - middle Callovian). To reconstruct some parameters of the sedimentary environments of the studied strata, evidences such as frequency and diversity of spores attributable to ferns, relative abundance of drier/wetter and warmer/cooler elements in different plant communities, ratio of palynological elements and palynofacies, presence of index shallow water dinoflagellate cysts for instance Dichadogonyaulax sellwoodii, Ctenidodinium spp., Valensiella ovulum, Pareodinia spp., Nannoceratopsis gracilis, abundance of proximate dinocysts forms, presence of fungal spores and warm - temperate water dinoflagellate (Gonyaulacysta centriconnata, Nannoceratopsis pellucida, Gonyaulacysta jurassica, Pareodinia ceratophora) are utilized. Based on the above criteria, the material examined seems to have been deposited in a marine margin, low oxygen environment, with low rate sedimentation, under hot and humid climate conditions, where the surrounding terrestrial vegetation was dominated by ferns.

The transformation of the contract is one of the solutions to prevent the contract. In the transformation of the contract, the principle of freedom of will and the cases that prevent this principle from applying this principle are discussed, how to determine the title of the contract according to the principle of custom, the will of the will, and its interpretations. The will of individuals has a sovereignty in regulating and concluding a contract, so it plays a key role in the interpretation of the contract between the parties to the contract. The principle of freedom of the will of the parties in the conclusion of the contract is limited in some cases. These are the barriers to the principle of will. When conflicting the true will of the parties to these obstacles, their agreement is condemned to invalidate. As a result, their contract is considered false. The nullity of the contract has disrupted the economic order of society and is contrary to the principle of contractual strength. In foreign law, if the false contract has another correct contract, it is transformed into the correct contract, which is called the transformation of the contract. But there is doubt about the existence of this institution in domestic law. The reason for this doubt is that neither in jurisprudence nor in subject law there is no independent issue regarding the transformation of the contract, although it is found. These instances in jurisprudence have been interpreted in issues such as virtual will and corruption of the marriage and the guarantee of the contract. In this study, the civil liability issues arising from the void of the contract in Iranian law be compared and examined in the plant. Manuscript profile -

At the same time as sustainable growth and development and fundamental developments in economic, social, and cultural affairs, the role of the road network appears as one of the important and fundamental parts in further development; In addition to the potential resources and talents, it makes the land fertile and provides the ground for growth and prosperity. Considering the correct and comprehensive criteria in the route determination stage can play a major role in reducing economic costs, increasing safety, and road accessibility and preserving the environment. For this purpose, in the current research, several factors such as slope, height, land use, geology, landslide, distance from the fault, distance from urban centers have been considered for optimal routing in Rudsar route. Therefore, in the current research, the shortest route on the Yasouj-Isfahan axis has been determined. The research method in this study is descriptive-analytical and ArcGIS software and AHP model were used for data analysis. According to the optimal route, it was chosen using this method due to its location in a suitable slope and close to the economic centers and far from the fault. The obtained results show that the obtained route is shorter in terms of duration and reaching the optimum than the previous route, and this will reduce the cost of fuel and reduce traffic.

This has raised the need to examine the impact of financial innovation and economic growth to protect countries from problems that may arise from financial sector market failures. With the growth in the global economy, it is one of the basic factors of financial innovation that is observed in developed and developing countries and creates fruitful results for the economy. The relationship between financial innovation and economic growth during the last few decades is one of the topics of concern for economists. In this study, using the PMG test, we test the effect of financial innovation indicators on economic growth in developed and developing countries for the period from 2000 to 2022. Three proxy variables have been used to calculate financial innovation: liquidity to the volume of money in circulation (M2/M1), bank credit to the private sector, and a proxy with mobile phone penetration is used to calculate the number of active internet subscribers to the population. In developed countries, in the long run, all the coefficients except the inflation rate are significant at the level of 5%. The effect of government spending, gross capital formation and trade liberalization on economic growth has been positive. The coefficients of M2/M1 and mobile phone penetration are negative and the reliability coefficient is positive. In developing countries, coefficients of M2/M1 and mobile phone penetration are negative and credits are positive. Financial innovation indicators M2/M1 and mobile phone penetration rate (MB) have a negative effect on economic growth. The growth of innovation cannot be the basis of economic development for developing economies; Because the infrastructure is not available in these countries. Manuscript profile -

For this reason, they are one of the most important factors in the decision-making process of information validity. The accuracy, reliability and value of the information are clarified by these networks. For this purpose, it is possible to check the validity of information with the features of these networks at the three levels of user, content and event. Checking the user level is the most reliable level in this field, because a valid user usually publishes valid content. Despite the importance of this topic and the various researches conducted in this field, important components in the process of evaluating the validity of social network information have received less attention. Hence, this research identifies, collects and examines the related components with the narrative method that it does on 30 important and original articles in this field. Usually, the articles in this field are comparable from three dimensions to the description of credit analysis approaches, content topic detection, feature selection methods. Therefore, these dimensions have been investigated and divided. In the end, an initial framework was presented focusing on evaluating the credibility of users as information sources. This article is a suitable guide for calculating the amount of credit of users in the decision-making process. Manuscript profile -

The development of artificial intelligence both at business and country levels depends on knowing the current situation. This paper identifies the artifacts and producers presented in this field and maps them to transformational levels. Products/services and producers are achieved through capabilities provided by artificial intelligence. Then, based on the classification methodology and meta-characteristics, the transformational levels of the artifacts of Iran's artificial intelligence ecosystem have been extracted. 562 products/services were identified, which were offered by 112 companies. Machine vision and natural language processing have been at the top of the technologies used, with 44 and 27 percent of the products allocated to them, respectively. Artifacts and producers were classified into seven transformative levels: individual, organization, industry, electronic chip/hardware, society, platform, code/algorithm/library, and infrastructure. Iran's artificial intelligence productions have not grown in a balanced way. The three levels of platform, code/algorithm/library, and infrastructure as the main generator of other artificial intelligence products/services have had the lowest amount of production. It is suggested that a specialized marketplace for the supply of artificial intelligence application programming interfaces should be put on the agenda to stimulate the formation of the ecosystem.

So, in recent years a considerable attention has been paid to patent and prior-art search. In process of patent application filing, searching in the previous patent database is of great importance. Patent examiners search in a huge database of patents to find if there exists any similarity between applicant’s claim and the previous registered patents. This process that called patent invalidity run, is one of the important stages of patent registration. Because of legal aspects of this process, the searcher should not leave any relevant patent document. So patent searching is essentially a recall-oriented issue in information retrieval applications. In recent years, the use of intelligent information retrieval in this search process has been investigated by many researchers. In this paper we investigate various methods of information retrieval that have been proven to be effective in retrieving relevant results. The survey also has focused on query formulation and how to transform a query patent into a search query. So we have explored different factors of a successful transformation, such as how many query words should be used, where to extract query words, how to weight them and whether to use noun-phrases instead of individual words. Furthermore, the survey covers researches that combine different features and has been proven to make a significant improvement in retrieval performance. Manuscript profile -

Malaysia, as one of the leading and developing countries in Southeast Asia, has examined its preparedness, opportunities, and challenges for adopting and developing this technology through the formulation of its IoT roadmap. Undoubtedly, the IoT roadmap in Malaysia is one of the most comprehensive documents in the study of macro-level Internet of Everything plans. This roadmap provides an analysis of Malaysia's current and future position in the IoT domain, including infrastructure, data and information, security, ecosystem, and talent, followed by a gap analysis. Studies show that the adoption of the next generation of information and communication technology in Malaysia has paved the way for the development of the IoE, outlined opportunities for economic innovation, and facilitated the commercialization of research outcomes by research organizations. The roadmap also emphasizes the importance of balancing development and security in this field, stating that with progress in this domain, Malaysia can emerge as a top hub and regional focal point for IoE development. The younger generation in Malaysia is highly interested in IoE, and they are not only consumers but also creative developers of this technology. This paper highlights Malaysia's recognition as a global pioneer in the IoE technology sector. The country has become a frontrunner in this field through advancements in infrastructure, increased domestic sales and exports, the development of services and platforms, emphasis on innovation, the importance of human resources, and, most importantly, the formulation of a comprehensive and complete IoT roadmap. Malaysia has benefited in two major ways: by deriving new value from technological innovation and gaining a competitive advantage and market share over governments unable to adapt and invest in the IoE market Manuscript profile -

In this study, the effects of depositional and post-depositional environments on the reservoir quality of zone A7 of the Asmari Formation in well No. 4 in Ahvaz oil field were studied. The study of the sequences of the Asmari Formation in this section led to the identification of 11 carbonate facies, one evaporite facies, one mixed carbonate-siliciclastic facies, and one siliciclastic facies. Sedimentary environments of tidal zone, lagoon, coral reef and open sea were introduced for the depositional environment of identified facies. Due to the absence of sudden changes, it seems that the studied deposits were deposited in a ramp-type carbonate platform that was influenced by siliciclastic sediments from the Zagros river systems. The immature sedimentary texture of the sandstone facies indicates the proximity of the origin of the quartz sources to the carbonate basin. Among the diagenetic processes that have affected the examined sequences, the following processes can be mentioned: micritization, cementation, neomorphism, physical and chemical compaction, dissolution, fracture development and filling, dolomitization, and anhydritization. These diagenetic processes occurred in post-depositional marine, meteoric and burial diagenetic environments. Many fractures were filled with petroleum, which indicates that fractures, along with dolomitization, chemical compaction, and fenestral pores, are among the most important post-sedimentation complications to increase reservoir quality. While cementation and anhydritization resulted in reducing the reservoir quality by closing the pore spaces . Manuscript profile -

For this purpose, 400 samples were selected and collected from a section of the Masjid Suleiman oil field and the surface section of the Asmari anticline in the Dezful depression and the Gurpi anticline in the Izeh zone. Petrographic studies revealed 18 sedimentary microfacies that were deposited on a ramp-type carbonate platform. Among the significant diagenetic processes in the region are the process of micritization, bioturbation and the influence of burrowing organisms, cementation (types of cement related to marine, meteoric and burial diagenesis environments), dissolution (meteoric and burial dissolution), dolomitization (in different phases), silicification, pyritization, phosphatization, mechanical compaction, chemical compaction, fracture and porosity. Based on the identification of the sequence boundaries and following the facies depth changes, the carbonate sequence of the Asmari formation in the subsurface section and the Asmari anticline section are introduced in the form of 3 sedimentary sequences of the third order shallowing upwards, which are the former Aquitanian, the late Aquitanian and Bordigalin belong.

In the current study, the carbonate successions of the Ilam Formation (Santonian) and their spectral gamma-ray data were chosen to identify the cycles and influencing factors on the sedimentation in one of the oilfields in the Dezful Embayment, southwest of Zagros mountains. According to available evidence, all of Milankovitch cycles contributed to changes in climatic conditions simultaneously with development of the Ilam Formation, however, the long Eccentricity cycles were dominant and have played a greater role in this issue. The sedimentation rate was estimated at 4-5.5 cm/kyr on average in the Ilam Formation. Considering the sedimentation rate and number of identified long Eccentricity cycles, it could be said the deposition in the Ilam Formation lasted in 1.13-1.8 Ma. Our results indicate that the relative sea-level changes in the studied wells correspond to the eustatic sea level. The deposition process in the Ilam Formation was largely affected by the performance of long Eccentricity cycles, eustatic sea level, and tectonic events during the Upper Cretaceous.

In the north of the Kerman Basin, Ordovician sedimentary sequences named Katkoyeh Formation have been introduced, which consist of 70 to 300 meters of siliceous siliceous rocks, one or two thin carbonate horizons in the upper part, and pyroclastic deposits. Traditionally, the Cambrian-Ordovician boundary in the Kerman Basin has been determined between the Hatken Dolomite Member of the Kuhbanan Formation (Late Furongian) and the Lower Shale Member of the Katkuye Formation. However, determining the location of the previous Tremadocine boundary is uncertain because no fossils have been documented from this interval. For the purpose of biostratigraphy of the Katkuye formation in Kerman basin, Gezoye section with an approximate thickness of about 170 meters was selected. In this section, the Katkoyeh Formation is located on the Hatken Dolomite Member and under the Shabjareh Formation sandstones of Silurian age. In the Gezoiye section, due to the action of basalt dikes and intense tectonics in the region, the limestone layers containing fossils have been severely altered, and during three sampling stages, 320 conodonts were recovered from the carbonate horizon of the upper part of this formation, and 3 Genus and 7 species were identified and based on this, three conodont ranges were recorded: 1) Icriodella superba Range Zone (Katian - ? Hirnantian; Late Ordovician), 2) Amorphognathus ordovicicus Range Zone (Katian - Late Ordovician), 3) Amorphognathus superbus Range Zone (Katian - ? Hirnantian; Late Ordovician). Late Ordovician age in the Katkuye formation in the Gezoye section with at least three species of the conodont genus Icriodella (I. superba, I. deflecta, (I. cf. discrete and two species of A. superbus) Amorphognathus, A. ordovicicus) determined and led to the identification of the Katian-?Hirnantian rocks.

For this purpose, these formations were investigated using NGS well log (one well ring), X-ray diffraction method (XRD) and XRF analytical method (11 samples from two wells). In the NGS log, the detected minerals are illite, montmorillonite, mixed layer, glauconite and feldspar. In the XRD method, clay minerals illite, montmorillonite, mixed layer, chlorite and kaolinite were identified in order of abundance.These minerals due to their sensitivity to react with water causes the instability of the borehole.

In order to investigate the stratigraphy and sedimentary environment, a section of this formation was selected in Khamir salt mountain section in Bandarlengeh embayment. In this number, 70 limestone microscopic thin sections and 3 marl samples (XRF) were evaluated to identify the microfacies and the sedimentation conditions.The petrographic study led to the identification of 10 microfacies belonging to the facies belts of tidal, lagoon, carbonate bar, open marine, which were deposited in the homoclinal carbonate ramp environment. The composition of marl facies oxides also indicates the presence of carbonate minerals, quartz and clay minerals, which along with field observations and alternating calcareous facies suggest that this facies was deposited in an open marine environment. Finally, it seems that the facies and fossil diversity of the Asmari Formation in the mentioned section is such that during the Aquitanian stage, this formation was located closer to the coast line and during the Rupelian and Chattian-Burdigalian times, it was located at a further distance from the coast line.

In addition, Pabdeh Formation is of special importance as one of the source rocks of Zagros Sedimentary basin. In order to study the Lithostratigraphic and Biostratigraphic rocks of Pabdeh Formation, the section of Ilam dam in the northwest of Zagros sedimentary basin has been selected and sampled. 360 samples were taken, of which 260 washing samples and 100 thin section samples were prepared. Based on the studies performed on these samples, 25 genera and 105 species have been identified in the Ilam dam section. 26 biozones and 2 sub-biozones have been identified based on the biological zoning of Wade et al., 2011 in the Tethys area. Based on the identified biozones, the age of Pabdeh Formation in the Ilam dam section, Middle Danian-Early Aquitanian has been obtained. The deposits of Pabdeh Formation in the section of Ilam dam have a thickness of 764 m (beginning of Pabdeh to the beginning of Kalhor anhydrite) which includes purple shale units (2 Units), marl limestone with lower limestone, cherti limestone, marl limestone with upper limestone. The lower boundary of Pabdeh Formation in this section is conform and continuous with shales and marls of Gurpi Formation but its upper boundary with the gypsums of the Asmari formation is most likely accompanied by a disconform.

Modernization, in this context, denotes transcending the traditional status quo and embracing renewal. Employing a descriptive and analytical approach rooted in reflection, and utilizing library methodologies alongside qualitative content analysis, the socio-political, economic, and cultural contexts of the emergence and evolution of this trend are explored. Additionally, its manifestations within Akhundzadeh's theatrical and non-theatrical oeuvre are examined and dissected. The "reflection approach," alongside methodologies such as "shaping" and "works as social institutions," constitutes one of the three primary approaches within the literary sociology tradition. In this framework, literary works serve as mirrors reflecting social realities. Depending on whether emphasis is placed on the form or content of the literary work, it draws upon various established theories, such as Lucien Goldmann's theory. In this study, a combination of library research and qualitative content analysis was employed to investigate the social, political, economic, and cultural contexts underpinning the emergence of the discourse on modernization. The findings reveal that the rapid social, political, economic, and cultural transformations of the period under consideration have exerted both positive and negative influences on the formation and content of Akhundzadeh's works. Consequently, the juxtaposition of traditional social paradigms with those stemming from the ethos of renewal emerges as a central theme within his body of work Manuscript profile -

The sediments of this formation are mostly composed of detrital rocks such as sandstone, sandy shales and sandy limestones. Phosphorite mineralization is mainly concentrated in the shales of middle parts of the Jeirud Formation. In this research, we have studied the concentration and the possibility of exploitation of rare earth and radioactive elements in these phosphorites. Lithogeochemical samples were randomly collected from phosphorite horizons. The samples were analysed by ICP-MS and ICP-OES not only for REE but also for major oxides and radioactive elements. The geochemical data show that the average of P2O5 is 29.60 %. The average of U and Th is 4.97 and 8.64 ppm respectively. Also, this data show that concentration of REEs in these samples are , 3times more than rare earth elements in North American shales (NASC) and 2.6 times more than Past Archaen shales (PAAS). REE concentration of these phosphorites were normalised to North American shales (NASC) and Past Archaen shales (PAAS). The spider diagram shows positive patterns to REE, especially in Ce and Eu. Also, this spider diagram represents the diffrentiation of LREE with respect to HREE. This diffrentiation occurred due to preferential absorption mechanism and during late diagenesis in these sediments. The average concentration of P and REE is realtively high and it seems to be economic for next minning activites. But the average concentration of U and Th is too low and not economic for exploration. Manuscript profile -

The Jeirud Formation (Late Devonian) is composed of about 45 meters of clastic sedimentary units in the southwest of Firoozkuh city, southern Alborz area. To carry out this research a field work was done during which a precise and detailed sedimentary log of the section was prepared and 52 samples from different lithologies of the formation were collected. Thin sections were prepared from all conglomeratic and sandstone samples, besides some thin sections were prepared from mudrocks and just 1 sample of paleosoil and then all were petrographically studied. In the study area, both basal and top boundary of the Jeirud Formation is disconformable with Mila and Mobarak formations respectively. All facies in the section include clastics (conglomerates, sandstones, mudstones and a paleosoil horizon). The facies were classified based on Miall classification so that conglomeratic facies comprise Gcm and Gmm; sandstone facies comprise Sh, Sp and Sm and mudrocks include Fl and Fm facies. Combined field and lab studies resulted in identification of two sedimentary facies associations including channel fill and flood plain facies associations. The reconstructed sedimentary environment of the Jeirud Formation in the Aro area represents a braided river depositional environment. The lower parts of this formation represent a finning-upward sequence which indicates deposition within a braided river channel subenvironment (conglomerates and sandstones) and the upper part is dominated with mudrocks with a paleosoil horizon representing deposition in a flood plain subenvironment.

Microfacies analysis, diagenetic features, and sequence stratigraphic evaluation of the Asmari Formation were carried out based on the petrographic investigation, petrophysical logs, and core measurement porosity and permeability data. Petrographic analyses led to the identification of twelve microfacies indicating five subenvironments including tidal flat, lagoon, barrier (belonging to inner ramp), middle ramp, and outer ramp, all of which are representing a homoclinal ramp. Tidal flat, lagoonal, and barrier microfacies are mostly present in the upper parts of the Asmari Formation, while middle and outer ramp microfacies were largely developed in the middle part. Cementation, compaction, dolomitization, dissolution, and fracturing are the main diagenetic processes in this formation. Compaction and cementation have negatively affected reservoir quality while fracturing, dolomitization, and dissolution contributed to reservoir quality enhancement. The sequence stratigraphic studies represent three 3rd order sequences of early Aquitanian, late Aquitanian, and early Burdigalian age based on the main features of microfaces, their depositional environments, and shallowing and deepening-upward trends. Microfacies of the Transgressive System Tract (TST) have been affected by compaction, dissolution (moldic), cementation, and slightly dolomitization in the middle to outer ramp parts. The Highstand System Tract in the inner ramp part has been affected by dolomitization, dissolution, and fracturing close to the sequence boundaries, and has a better reservoir quality than the Transgressive System Tract.

The studied section, with a thickness of 314 m, consists of medium to thick-bedded to massive limestones and shale. The Qom Formation overlies the Eocene volcanic rocks in the Ghamsar section and is covered by the Recent alluvial sediments. A total of 21 genera and 9 species of benthic foraminifera were identified in this section and the results indicated the age of Rupelian-Chattian. According to the above palaeoecological conditions, in the lower parts of this section (Rupelian), light conditions are euphotic and nutrient conditions are first eutrophic and then Meso-oligotrophic with mainly normal sea salinity. During Chattian, the trophic state was mainly meso-oligotrophic with normal salinity, and salinity varied between 40 and 50 PSU. Light conditions also were between aphotic and mainly meso-oligophotic. Large benthic foraminifera with hyaline walls, such as Amphistegina, Lepidocyclinide and Nummulitide, in shallow environments with high energy, have thicker shells and smaller shell size, and in deep environments, due to reduced light intensity and low water circulation, they have thinner and more elongated shells. The results of the morphometry of 186 samples of Amphistegina show that the seawater depth in Ghamsar section (Rupelian-Chattian) fluctuated from less than 11 meters to less than 44 meters.

Consequently, when changes occur, adaptation and coordination become necessary. The architectural landscape in Iran, with its long history and remarkable works, has been rapidly and multi-dimensionally shaped by the developments of the 20th century. This has sometimes led to conflicts between the past and the desired future, resulting in periods of confusion regarding the direction of progress. The paper aims to investigate the effective components in the formation of contemporary Iranian architecture based on social changes. The research methodology employed in this study is qualitative and follows an analytical-historical approach. Content analysis consists of three stages: preparation and organization, examination of materials and messages, and data processing and conclusion drawing. These stages are conducted using MAXQDA software. Additionally, graphical representations are generated based on the research components. Gafi stands out as one of the notable programs in this regard. The results indicate that social changes over time have significantly influenced the evolution of contemporary architecture in Iran. Factors such as political, economic, cultural, climatic and environmental consideration have distinctly shaped contemporary Iranian architecture during different historical periods.</p> Manuscript profile -

This has raised the need to examine the impact of financial innovation and economic growth to protect countries from problems that may arise from financial sector market failures. With the growth in the global economy, it is one of the basic factors of financial innovation that is observed in developed and developing countries and creates fruitful results for the economy. The relationship between financial innovation and economic growth during the last few decades is one of the topics of concern for economists. In this study, using the PMG test, we test the effect of financial innovation indicators on economic growth in developed and developing countries for the period from 2000 to 2022. Three proxy variables have been used to calculate financial innovation: liquidity to the volume of money in circulation (M2/M1), bank credit to the private sector, and a proxy with mobile phone penetration is used to calculate the number of active internet subscribers to the population. In developed countries, in the long run, all the coefficients except the inflation rate are significant at the level of 5%. The effect of government spending, gross capital formation and trade liberalization on economic growth has been positive. The coefficients of M2/M1 and mobile phone penetration are negative and the reliability coefficient is positive. In developing countries, coefficients of M2/M1 and mobile phone penetration are negative and credits are positive. Financial innovation indicators M2/M1 and mobile phone penetration rate (MB) have a negative effect on economic growth. The growth of innovation cannot be the basis of economic development for developing economies; Because the infrastructure is not available in these countries. Manuscript profile -

Occurrence of high abundant and diverse miospores in the Qadir Member (Nayband Formation), from the exploratory well no. 954 (Exploratory Area of Parvadeh 4), south of Tabas, central Iran allows for this method to be used to obtain certain palaeoecological implications. By classifying spores and pollens (sporomorphs) in Sporomorph EcoGroups (SEGs), all six plant ecogroups (including plants adapted to Upland, Lowland, River, Pioneer, Coastal, and Tidally-influenced) were identified in examined material. The high ratio of warmer/cooler sporomorphs and the low ratio of drier/wetter sporomorphs suggests deposition under a moist, ±warm climate during the Late Triassic in south of Tabas. From the investigation of miospore parent plants, it was approved that, in descending order, pteridophyta (44%), cycadophyta (34%), coniferophyta (9%), lycophyta (8%), pteridospermophytes (2%), ginkgophytes (2%) and bryophyta (1%) were surrounded the environment of the studied formation. Notable abundance of fern spores (Kyrtomisporis and Foveogleicheniidites) and cycads pollen (Ovalipollis and Ricciisporites) in the palynofloras studied indicate the predominance of warm to semi-warm climate with high humidity. Paleogeographic position of Iran during the Late Triassic in the southern active margin of Eurasia (Turan Plate) tends to support this palaeoclimate generalization. Manuscript profile -

Then, while briefly introducing the space of computer security encounters in the form of ontology, three perspectives in the study of patterns in this field have been identified and distinguished from each other. These three perspectives are secure models, security models, and the framework and system to security models. The first and last perspectives are briefly explained and the second perspective is studied in detail from the perspective of the organization of patterns, including the five types of organization. The five types mentioned include software-based lifecycle organization, logical-level organization-based organization, threat-based classification-based organization, attack-based classification-based organization, and application-based organization. In this type of introduction of patterns, the audience acquires a comprehensive view of the discourse of computer security patterns and acquires the necessary knowledge to make better use of these patterns. Finally, the analysis and idea of this research are presented in the form of introducing a new type of organization in order to facilitate the proper use and addressing of patterns. It is stated that the existing categories are mostly static and forward-looking and do not have the necessary dynamism and backwardness, and the idea of covering all stakeholders and security ontology can have this feature and, include agile patterns as well. Based on this idea and related analyzes, the atmosphere of future research activities will be revealed to the audience. Manuscript profile -

The purpose of this article is to identify and analyze the key drivers of digital signature implementation in Iran with a fuzzy Delphi approach. In terms of practical purpose and in terms of information gathering, the research has benefited from a hybrid approach. The statistical community consists of all experts and specialists in the field of information technology and digital signature and articles in this field. The sample size of the statistical community of experts is 13 people who were selected by the purposeful sampling method. 31 articles were selected based on their availability and downloadable, non-technical nature, and relevance to the topic. The method of data analysis was done according to the fuzzy Delphi approach. Validity and reliability were calculated and confirmed using the CVR index and Cohen's kappa test with coefficients of 0.83 and 0.93, respectively. The results prove that the key drivers of digital signature implementation in Iran include 5 main dimensions and 30 concepts, which are 1) security (information confidentiality, information security, sender authentication, document authentication, privacy protection, trust between parties), 2) business (digital business models, communication needs, staff management, organization size, organizational structure, organization resources, organizational culture, top managers, competition ecosystem, e-governance), 3) user (perceived convenience, perceived benefit, consumer behavior, consumer literacy, consumer lifestyle), 4) technical (development of technical infrastructure, systems integration, system complexity, system tanks, design quality, technical speed of certificate production and verification, impermeability of hackers) and 5) Legal (legal licenses, penal laws, legislative body, e-commerce laws). It is suggested that in the field of digital signature implementation, special attention should be paid to rewriting rules, training users, creating a security culture, and digital signature policymakers should invite knowledge-based companies to cooperate in developing infrastructure and making relevant software competitive.

On the other hand, information retrieval has emerged as one of the major problems in the area of algorithms and computation. As graph-based information retrieval algorithms have shown to be efficient and effective, this paper aims to provide an analytical review of these algorithms and propose a categorization of them. Briefly speaking, graph-based information retrieval algorithms might be divided into three major classes: the first category includes those algorithms which use a graph representation of the corresponding dataset within the information retrieval process. The second category contains semantic retrieval algorithms which utilize the graph theory. The third category is associated with the application of the graph theory in the learning to rank problem. The set of reviewed research works is analyzed based on both the frequency as well as the publication time. As an interesting finding of this review is that the third category is a relatively hot research topic in which a limited number of recent research works are conducted. Manuscript profile -

Debris deposits of this formation have wide outcrops in the northern area of Bandar Abbas city. In order to study the Bakhtiari formation from the point of view of sedimentary geology, three sections of this formation were selected in the northwest of Bandar Abbas city (Genow Power Plant, South of town Down Tazeyan, South of town Morvarid). From these sections, 50 samples were taken for microscopic examination and 6 samples were taken to identify heavy minerals. In all three sections, the Bakhtiari Formation includes an interval of conglomerate, sandstone and some mudstones. In the studied area, this formation is placed on the Aghajari formation with an erosional discontinuity boundary. The upper border of the Bakhtiari Formation with Quaternary deposits is also of erosional discontinuity. Field and laboratory investigations led to the identification of coarse-grained petrofacies (mud-supported conglomerate and grain-supported), medium-grained (calclitite sandstone), fine-grained (mudstone) and five structural elements (GB, CH, SB, GH, FF) has been. The results of this research show that the deposits of the Bakhtiari Formation in the north west of Bandar Abbas has been deposit in a braided river far from origin at the end of an alluvial fan. The set of heavy minerals identified in this sequence have two origins, Hormuz Salt Series and Sanandaj-Sirjan Zone, which have been affected by several sedimentary cycles. The set of petrofacies features of the Bakhtiari Formation is a confirmation of the tectonic dynamics of the end of the Cenozoic era in the middle Pliocene-Pleistocene time frame, especially the Bakhtyari tectonic event, which has led to the intensification of continental conditions in the studied area.

For this purpose, cities, inspired by new technologies, provide urban services to improve the quality of public services in the community. This new attitude towards cities can improve the living conditions of their inhabitants. Therefore, a new and conceptual look is needed in a smart city to give it a new framework. The main objectives of smart cities are to optimize urban activities, boost economic growth, and improve the quality of life of citizens. The research focuses on the concept of a smart city, its objectives, and its indicators. The present research methodology is a descriptive-analysis of the type of application that collects the required data using library information and authoritative articles. The results show that smart cities have reached indicators such as management, energy, building, transport, urban services and therapy, technology, and smart citizens. Key areas of smart cities include economics, people and governments, the environment, and smart living, which can lead to greater energy efficiency, increased yield, careful analysis of consumption, and data collection. As a result, these experimental measures will promote the development of cities, creating new insights that will improve the living conditions of their inhabitants. The new definition will inform future generations and their work in cities, communities, and achieving cities with intelligent concepts. Manuscript profile -

Over the past two decades, Iran's major cities have witnessed significant developments in the construction of commercial complexes, which have also become symbols of social and cultural significance. The aim of this research is to analyze the factors influencing the formation of consumer culture in these complexes and their social, cultural, and economic impacts. The primary issue addressed in this paper is how economic transformations, globalization, social changes, and modern technologies affect consumer culture in commercial complexes of metropolises. Specifically, the research question focuses on how these factors have altered consumption patterns and purchasing behaviors, and what effects they have on social interactions and cultural identity. The research methodology involves analyzing existing literature, conducting interviews with experts, and evaluating field data from various commercial complexes. This approach examines economic and social changes and their impact on consumer patterns, while also analyzing the effects of technology and globalization on consumer preferences. The findings indicate that commercial complexes function not only as shopping centers but also as important social and cultural spaces. Economic changes and increased household incomes have led to higher demand for luxury goods, while globalization and modern technologies have influenced consumer preferences. These complexes provide opportunities for social and cultural interactions and contribute to the economic development of metropolises.</p> Manuscript profile -

Researchers who use common statistical methods on compositional data ignore spurious correlations, which causes incorrect results. This article introduces transformations for opening closed system of compositional data. These transformations include the additive logarithmic ratio (alr), the centred logarithmic ratio (clr), and the isometric logarithmic ratio (ilr). They are all defined in terms of logarithms of ratios. We then applied the clr transformation to a soil chemical data set. We also analysed the results of applying cluster analysis on the clr transformed data using Spearman's correlation coefficient matrix as distance. We also investigated how applying clr transformation affects spurious correlation, skewness and outliers in the data using R statistical software.</p> Manuscript profile
