        In different steps of steel production, various defects appear on the surface of the sheet. Putting aside the causes of defects, precise identification of their kinds helps classify steel sheet correctly, thereby it allocates a high percentage of quality control process. QC of steel sheet for promotion of product quality and maintaining the competitive market is of great importance. In this paper, in addition to quick review of image process techniques used, using image process by means of Gabor wavelet, a fast and precise solution for detection of texture defects in steel sheet is presented. In first step, the approach extracts considerable texture specification from image by using Gabor wavelet. The specification includes both different directions and different frequencies. Then using statistical methods, images are selected that have more obvious defects, and location of defects is determined. Offering the experimental samples, the accuracy and speed of the method is indicated. Manuscript profile

        In different stages of steel production, many defects appear on the surface of the sheet. Regardless of the causes of failures, accurate detection of their types helps to correctly classify the steel sheet and thus occupies a high percentage of the quality control process. Quality control of steel sheets is of great importance in order to improve product quality and maintain a competitive market. In this article, while reviewing the used image processing techniques, by using image processing with the help of two-dimensional Gabor wavelet, a fast and high-accuracy solution is presented for revealing textural defects of steel sheets. At first, using Gabor wavelet, it extracts significant textural features from the images, which includes both different directions and different frequencies. Then, using the statistical method, the images that contain the defects are selected more clearly and the location of the defect is determined. By presenting test samples, the accuracy and speed of the method used have been shown. Manuscript profile

        The presence of hot springs, travertine outcrops, hydrothermal altered area and active tectonic in the north-east of Takab city in the West Azarbayjan province indicate that there is a geothermal system in the area. In order to characterize the geological structures associated to the geothermal system in the region, a gravity survey was carried out in 140 stations which covered an area about 600 km2. Necessary modifications such as Bouguer, topography and free air were applied over data to obtain complete Bouguer anomaly field. Then, residual gravity anomaly field was calculated by subtracting the regional gravity field from complete Bouguer field. The regional gravity field was calculated by fitting a three-order polynomials surface over the complete Bouguer field. The calculated residual gravity map shows two negative anomaly zones (A1 and A2) in the study area. In geothermal exploration, negative gravity anomalies are considered as probable reservoir of geothermal systems. The horizontal and vertical derivative maps show complicated fracture zones in the study area. To obtain more information, the depth estimation carried out using Euler method. Estimated depth for the top of negative anomaly source in zone 1 is between 1000 and 2000 m. Finally, 3D inversion of the data was performed using Li and Oldenburg algorithm to show an image of the reservoir in the depth. The results of 3D inversion show a significant negative density contrast that occurred only in zone 1. Therefore, the reservoir of the Takab geothermal system is located in the depths between 3000 and 5000 m in A1 anomaly zone. Manuscript profile

        The study area is located 35 kilometers northwest of Tabriz. Based on stratigraphic evidences, age of volcanic rocks in Monavvar area is Mio-Pliocene and Plio – Quaternary. According to geological structure, it is part of the western Alborz – Azerbaijan zone. Most of the volcanic rocks are dacite, rhyodacite, andesite, basaltic andesite and trachyandesite. In the spider diagrams these rocks show enrichment of HREE and HFSE elements over LREE and LILE, depletion and negative anomalies for Ti, Nb and Ta (TNT) and Ba/Nb, Ba/Ta. These properties indicate that their formation could occur in the continental arcs and post collisional arcs. High levels of SiO2 equal to 55 to 66 %wt, low levels of MgO, Y, Yb and Sr/Y and La/Yb represent the formation of high silica adakitic magma in the region. According to this evidence and REE distribution patterns, formation of magma was probably from asthenospheric mantle garnet – lherzolite source. Manuscript profile

        5 - Fractal analysis of the aftershocks of the 2013 Gosht-Saravan (M.7.8) earthquake, NE Makran

        In this paper the fractal dimension of the aftershocks of the 2013 M 7.8 Gosht-Saravan earthquake and their relationship with the seismicity parameters (such as the b-value) and also the released seismic energies of the main shocks and the aftershocks are investigated. More
        In this paper the fractal dimension of the aftershocks of the 2013 M 7.8 Gosht-Saravan earthquake and their relationship with the seismicity parameters (such as the b-value) and also the released seismic energies of the main shocks and the aftershocks are investigated. The Gosht-Saravan main shock is an intraslab event with normal mechanism. No relationship between the Saravan fault and the main shock is observed. By examining the fractal dimension of the aftershocks and their relationship with the b-value it is confirmed that a linear seismic source (such as a subduction zone) exists. The slip ratio between the primary and secondary faults can be estimated by the fractal dimension. The calculated slip ratio indicates that a low portion of the slips may be related to the near surface fractures which can be verified by the shallow depth aftershocks. The earthquake occurrence in the intermediate depth, releases seismic energy and migrates to the near surface faults and fractures. The occurrence of aftershocks both near the hypocenter and at shallow depths can confirm the activity of these faults. The ratio of the total radiated seimic energy of the aftershocks to the radiated seimic energy of the main shock indicates that a high fraction of the energy related to the main shock and just a small fraction of the energy related to the aftershocks.

        The kopet- Dagh zone undergone subsidence and deposition of sediments after middle Cimmerian orogeny in middle Jurassic to Eocene. 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

        Postmodernism, by deconstructing all the foundations and meta-narratives, has created a situation in which pluralism is the basis for policy-making. While some scholars have spoken of the refusal to form politics in the postmodern space, and have considered the lack of a basis for establishing political theory inappropriate, others have sought to establish a policy appropriate to this space, both theoretically and practically. Among them is "William Connolly", who, by inventing concepts such as multidimensional pluralism, onto-politics, politics of becoming, critical responsiveness, and agonistic respect, explained postmodern politics, and proportionate with multiplicity, pluralism, dispersion, and diversity of identities has proposed a practical solution. Agonistic democracy, which of course includes other founders and proponents such as Chantal Mouffe, David Owen, and James Tully, is a viable alternative to deliberative democracy and attends it as an inclusive, contingent, and accountable political life, by respectful contestation of wonderful, different and even contradictory new identities. Uncertainty, unpredictability, juxtaposition of divine and atheistic beliefs in the context of the multiplicity of gender, linguistic, racial and cultural identities are some of the components that Connolly has considered and explained in postmodern politics.

        One of the basic and important research fields in wireless sensor networks is how to place sensor nodes where by using minimum number of sensor nodes all target points are covered and all sensor nodes are connected to the sink. In this paper, a novel method based on imperialist competitive algorithm is used for solving the mentioned problem. In the proposed method, a colony can immigrate from a weak empire to more powerful empire. The idea of immigration is inspired from human society in which a human can emigrate from a country to another country. The network is supposed to be a three-dimensional grid network and the sensor nodes can be only placed at cross-points of the grids while the target points can be deployed at each point of three-dimensional space. The simulation results show that the proposed method uses fewer number of sensor nodes than other similar algorithms and has the less running time. Manuscript profile

        The current research was conducted with the aim of comparing the effectiveness of pre-marriage trainings using the method of interpersonal awareness and choice program and the multi-dimensional local-oriented approach on couples' dysfunctional beliefs in people applying for marriage. The method of the present research is a semi-experimental type with a pre-test-post-test design with a control group. The statistical population of the present study included all the people who applied for marriage in Arak city, and among them, 60 people were randomly selected in three experimental groups of the awareness and selection program. Interpersonal, indigenous education group and control group were included. In this study, the content of the pre-marriage training sessions based on the principles and techniques of the interpersonal awareness and choice program (PICK) in two 90-minute sessions per week and multi-dimensional indigenous education in ten 40-minute sessions Done. The data collection tool was communication beliefs inventory and analysis of covariance was used to analyze the data. Based on the results, there was a significant difference between the effectiveness of pre-marriage education by the method of interpersonal awareness and selection program and the multidimensional local-oriented approach on communication beliefs in two beliefs related to the belief of expectation of mind reading and the belief that the spouse will not change. Another result is that in the program of pre-marriage education by the method of awareness and interpersonal choices program, people learned that communication and compatibility with the future spouse is much more complicated than matching or having no dissimilarity with him and it is necessary to behave with including self-sacrifice in improving relationships and increasing satisfaction, play their role.

        Place enjoys some specific characteristics which are accepted by all thinkers; for example, place is the receptacle of the emplaced; the emplaced occupies place; it is impossible for two emplaced things to exist at the same time in the same place; the emplaced can seek for a place or leave it through motion; place can be divided into smaller places, etc. Accordingly, the existence of place in the outside is considered to be evident, and if there are any disagreements, they pertain to the nature of place. Now, the question is which entity possesses the above-mentioned characteristics. There are certain views which are clearly inconsistent with some of these features and are, therefore, rejected; for example, the place of a thing is the same as its matter or form. Regarding this issue, Aristotle’s view is more acceptable than others and has been confirmed by Farabi and Ibn Sina. They believe that place is the internal surface of the container which is tangent with the external surface of the contained. The next view which is supported by some well-known philosophers indicates that place is the immaterial dimension. However, the idea of some mutikallimun entailing that “place is the same imagined vacuum” is rejected in the view of philosophers because it refers to vacuum. Finally, more recent philosophers interpret place as volume. Manuscript profile

        Fancisco Suárez (1548-1617) was the last great scholastic philosopher of the Western Renaissance. He opened up new horizons for his contemporary Scholars regarding certain philosophical and metaphysical discussions. Although he was an advocate of Aristotelian- Thomistic tradition, he believed that metaphysics was in demand of certain fundamental modifications. Aristotle, on the one hand, emphasized the unity of the subject of science and, on the other hand, spoke as if he believed in the existence of multiple subjects for metaphysics. Post-Aristotle philosophers, from Greek and Alexandrian philosophers to Islamic and Christian ones, particularly and most importantly Ibn Sīnā, made great efforts to remove the existing inconsistencies. In his Disputationes Metaphysicae (Metaphysical Disputations), through examining the various ideas that had been propounded in this regard until his time, Suárez presented a new approach and introduced “being qua being” as the subject of metaphysics. In order to further explain his view, he elaborated on certain expressions such as “real being” as opposed to actual being and “mental being” as opposed to formal being. Moreover, he maintained that real being is a “general mental concept of being in its nominal sense”. In this paper, through a meticulous study of the meaning of “real being” in Suárez’s view, the authors intend to investigate and evaluate his place in the tradition and history of philosophy regarding the subject of metaphysics.

        In the history of philosophy and philosophers’ thoughts, God has been discussed differently as the unmoved mover, thought of thought, cause of causes, and the first cause. One of the philosophers who greatly influenced the reformist movements of the church in the 16 and 17 centuries was Fancisco Suarez. His book of Metaphysical Disputations, which comprises 54 disputations on some topics such as general ontology and causes and particular ontology and types of cause, holds a supreme place in the history of philosophy. The present study aims to provide an answer to the questions of what place Suarez has allocated to the discussion of God, and which approach he follows in discussing Him. Another question here is whether one can conceptually reduce all the various names that he has chosen for God based on his own philosophy to a single concept. The findings of the study reveal that Suarez considered three places for God: God as the Efficient Cause, God as the Final Cause (in the first volume of Metaphysical Disputations), and God as Being (in the second volume of the same book). Given Suarez’s definition and explanation for each of these titles, all of them can be explained in terms of an ontological concept and meaning. He follows a philosophical approach to all three stations; however, he also adopts a theological approach to discussing God in the third one and connects the discussion of God to the text of the Holy Book.

        Aristotle’s Metaphysics is perhaps the most fundamental work in the field of philosophy. The importance of this book is to the extent that it is now about 2000 years that its name is used to refer to first philosophy (philosophia prima) and theology. It is at least 1500 years that metaphysics is viewed as a science that discusses the basic principles, first causes, and subjects in particular sciences. Metaphysics, which was initially called first philosophy and universal science, consisted of two parts, one speaking of absolute existence and its essential accidents and the other discussing theology. Accordingly, the philosophers of the Islamic world called first philosophy or universal science theology and divided it into two parts: general affairs or theology in the general sense of the word, which discusses existence and its principles, causes, and accidents, and particular theology or theology in the particular sense of the word, which deals with problems related to oneness and attributes, names, and acts of the Almighty Necessary. Islamic philosophers were unanimous at least regarding the basic principles and many essential problems. However, in modern Western philosophy, metaphysical problems have developed a new form and, thus, different fields of philosophy have come into existence. The philosophers of the modern era, from the time of Descartes until now, have provided a definition for metaphysics which is apparently different from Aristotle’s. Instead of defining and describing this science, they have defined their own philosophy. The present paper aims to clarify the nature of metaphysics through a historical analysis of the subject of this scientific discipline. Manuscript profile

        Man’s corporeal dimension is of great significance from various angles in Mullā Ṣadrā’s anthropology. In this paper, the authors deal with one of its important dimensions, that is, its ontological functions. Mullā Ṣadrā has not allocated any independent section to the functions of Man’s corporeal dimension in his works and has not even directly referred to it. However, these functions can be inferred from his views. A study of his works indicate that Man’s corporeal dimension performs some important functions from an ontological perspective. In this regard reference can be made to the following functions: developing belief, promotion and evolution of Man, having free will, performing opposite acts, completing mental and rational acts, constructing and improving the world, realizing the noblest order, granting identity to the soul, and developing the identity of the perfect Man and some apparently contradictory roles such as becoming the source of evil and the source of freedom from evil. This study, which has been conducted following the library and content analysis methods, in addition to demonstrating the significance and necessity of Man’s corporeal dimension in the world of creation, illustrates that the functions of this dimension have various aspects from an ontological viewpoint and pertain to a number of important realms in the world of being.

        One of the issues and problems facing the research cycle is the integration of design and production. Research institutes design products that are made without the cooperation of the construction engineering firm. The manufacturing institution does not have a common language in the production of the designed product and therefore no production takes place. Design without considering production and supply considerations seems beautiful only for the designer, but in some cases, the production organization is either not able to produce it or has problems in supplying some parts. This research deals with the issue of coordination of design, production and supply, which by examining the literature, its key indicators at the level of research projects and industrial development were extracted and finally ranked with decision models. For the first time, this research examines concurrent engineering in the defense industry and provides a model for the integration of design, production and supply. The indicators of this issue are divided into 4 criteria of product structure and architecture, management, quality and organizational cooperation. The criteria of product structure and architecture are the most important. Manuscript profile

        Data warehouse and OLAP are essential elements of decision support systems (DSS) and have been studied in database issues extensively. The requirements of decision support systems are different from on-line transactional processing systems. Query optimization and efficient data cube computation have primary roles in improving functionality of DSS. This paper presents a new method for query processing in data warehouses and computing data cubes using bottom-up cube computation techniques. Results of implementation show that the proposed algorithm outperforms two best known algorithms (based on time criterion), and is much faster than them in answering to monotonic query with large volume of data. Furthermore, 2-dimensional view of ex-cube and transforming the data cube to a hyper graph structure, reduce the required space of the algorithm when we aggregate subsets of cube's dimension.

        In this paper, experimental modeling of two-dimensional discrete systems with ARMA structure is considered. Therefore two-dimensional model order selection and parameter estimation problems are proposed. This method shows that the information of AR and MA orders are implicitly contained in two different correlation matrices and the AR and MA orders of the 2-D ARMA model can be independently determined before parameter estimation. The two-dimensional model is assumed to be causal, stable, linear, and spatial shift-invariant with quarter plane (QP) support. Numerical Simulations are presented to show the good performance and effectiveness of the proposed method in two-dimensional discrete system with ARMA structure. Manuscript profile

        In this work, in order to increase the capacity of a recurrent neural network, we present a model for extracting common features and sharing them across data. As a result of using this model, extracted principle components of data will be invariant to unwanted variations. The recurrent connection of the network removes the noise using a continuous attractor formed during the training phase. The defined speaker codes will be transformed to the information need for switching the continuous attractor in the input space. As a result, speaker variations can be compensated and the recognition will performed when a clean signal is available. We compared the performance of this method with a reference network described in the paper. The results show that the proposed model is more useful in removing noise and unwanted variations. We compared the performance of this method with the reference network. The results show that the proposed model performs better in removing noise and unwanted variations, it increased the phoneme recognition accuracy about 5% when the signal to noise ratio is 0 dB.

        The use of metaheuristic algorithms is a good choice for solving optimization problems. In this paper, a novel feature selection algorithm based on Ant Colony Optimization (ACO), called Advanced Binary ACO (ABACO), is presented. This algorithm is an advanced version of binary ant colony optimization, which attempts to solve the problems of ACO and BACO algorithms by combination of these two. The performance of proposed algorithm is compared to the performance of Binary Genetic Algorithm (BGA), Binary Particle Swarm Optimization (BPSO), and some prominent ACO-based algorithms on the task of feature selection on 12 well-known UCI datasets. Simulation results verify that the algorithm provides a suitable feature subset with good classification accuracy using a smaller feature set than competing feature selection methods.

        The performance of Networks-on-Chip is highly dependent to the incorporated routing algorithms. In recent years, many routing algorithms have been proposed for 2D and 3D Networks-on-Chip. In 3D integrated circuits, different devices are stacked through silicon via in which the vertical connections are vulnerable to manufacturing process variations. Therefore, because of the high impact of faulty links or nodes on the performance of a Network-on-Chip, utilizing a fault-tolerant routing algorithm is of great importance especially for 3D Networks-on-Chip in which the vertical links are more vulnerable. In this paper, a new fault-tolerant routing algorithm called FT-ZXY is proposed to be used in 3D Networks-on-Chip. This routing method is capable of tolerating multiple vertical faulty links in addition to single horizontal faulty links without using any virtual channels thus incurs a very low hardware overhead. Experimental results reveal that the proposed routing algorithm has more reliability compared to the previous designs while incurs less latency and requires lower area and power overheads.

        Combination of 3D stacking and network-on-chip (NoC), known as 3D NoC, has several advantages such as reduced propagation delay, chip area and interconnect, and power consumption, and bandwidth increase. Despite these advantages, 3D stacking causes the increased power density per chip area and subsequently increases the chip temperature. Temperature increase causes performance degradation and reliability reduction. Therefore, design of temperature management algorithms is essential for these systems. In this paper, we propose a task migration scheme for thermal management of 3D NoCs. The process of migration destinations for hot spots is an NP-complete problem which can be solved by using heuristic algorithms. To this end, we utilize a simulated annealing method in our algorithm. We consider migration overhead in addition to the temperature of the processing elements in migration destination selection process. Simulation results indicate up to 28 percentage peak temperature reduction, on average, for the benchmark that has the largest number of tasks. The proposed scheme has low migration overhead.

        This paper proposes to design, optimization and finite element simulation of an axial-flux, super-high speed, permanent magnet motor. The target motor with 0.5 hp rated power at speed of 60,000 rpm is used in a special industrial application. Based on nominal specifications of the motor and using analytical relations of motor design, the design calculations, sizing and motor dimensions are investigated. Due to special application of the target motor that needs to the demanded torque with minimum current and copper losses, the dimensions and design specifications of motor is optimized via genetic algorithm based on a torque per ampere cost function. Optimization algorithm determines the optimum value of airgap, permanent magnet flux density, current density and turns number of stator windings. To demonstrate of analytical design and optimization results, using 3-D model of motor in Maxwell software, finite element analysis are carried out in Magneto-static and Transient modes. The FEM simulation results confirm the analytical design results. Moreover, they show the significant reduction in RMS current and copper loss at rated torque. There is a good agreement between the values of torque, motor efficiency, and flux density resulted from both methods. Manuscript profile

        Three-Dimensional Chips are made of stacking silicon layers which communicate with each other by Through-Silicon-Via (TSV) links. Manufacturing cost of Three-Dimensional chips is a function of the number of TSVs because the fabricating of a three-dimensional chip with fully vertical links is of high cost and high fabrication complexity. The packet routing strategies in the 3D NoCs with partially TSVs is more complex than that in the 2D NoCs. In this paper, we proposed a routing algorithm for the 3D NoCs with partial TSVs, which provides a dynamic routing with maximum adaptivity for packets by dividing the network into three groups of layers, rows and columns. This algorithm is independent of vertical channel's position but related to layer number of the current packet and based on the layer number, odd or even, uses a special turn strategy to route packets on rows and columns with odd or even numbers. The proposed routing algorithm mitigates deadlock and livelock with only two virtual. The experiments show that average packet latency in proposed algorithm is 32.8% smaller than that in Elevator_First which is a well-known algorithm for packet routing in 3D chips. Also, this improvement on average packet latency and network throughput will be more with increasing on network size and reduction on TSV number. Manuscript profile

        Nowadays, with the advent and proliferation of high-dimensional data, the process of feature selection plays an important role in the domain of machine learning and more specifically in the classification task. Dealing with high-dimensional data, e.g. microarrays, is associated with problems such as increased presence of redundant and irrelevant features, which leads to decreased classification accuracy, increased computational cost, and the curse of dimensionality. In this paper, a hybrid method using ensemble methods for feature selection of high dimensional data, is proposed. In the proposed method, in the first stage, a filter method reduces the dimensionality of features and then, in the second stage, two state-of-the-art wrapper methods run on the subset of reduced features using the ensemble technique. The proposed method is benchmarked using 8 microarray datasets. The comparison results with several state-of-the-art feature selection methods confirm the effectiveness of the proposed approach.

        Since in wireless sensor networks, selection of next hop is critical in attack avoidance and lowering the power consumption, a method based on fuzzy logic is proposed in this paper considering status and report transmission of the nodes. In this method, the next hop is selected considering four factors, based on fuzzy logic system. These factors, indicating four optimized parameters; i.e., degree of node proximity to the shortest path, degree of node proximity to the sink, residual energy ratio of each node, and the number of false filtered messages. This method leads to an increase in energy level as well as maintaining security level in comparison with LEAP protocol. Meanwhile, it is possible to identify safe paths. Comparing with other related methods, it is shown that this method leads to significant reduction in energy consumption level and consequently the life-time of the network is increased. Meanwhile with selecting the appropriate next hop, packet drops are reduced as well. Manuscript profile

        The steganalysis purpose is to prevent the pursuit of steganography methods for your goals. In steganography, in order to evaluate new ideas, there should be known steganalysis attacks on them, and the results should be compared with other existing methods. One of the most well-known steganalysis methods is CDF method that used in this research. One of the major challenges in the image steganalysis issue is the large number of extracted features. High-dimensional data sets from two directions reduce steganalysis performance. On the one hand, with the increase in the dimensions of the data, the volume of computing increases, and on the other hand, a model based on high-dimensional data has a low generalization capability and increases probability of overfitting. As a result, reducing the dimensions of the problem can both reduce the computational complexity and improve the steganalysis performance. In this paper, has been tried to combine the concept of the maximum weighted clique problem and edge centrality measure, and to consider the suitability of each feature, to select the most effective features with minimum redundancy as the final features. The simulation results on the SPAM and CC-PEV data showed that the proposed method had a good performance and accurately obtained about 96% in the detection of data embedding in the images, and this method is more accurate than the previously known methods.

        Digital Rock Physics (DRP) is a newly developed method to numerically compute rock physical properties such as permeability, elastic moduli and formation factor using highresolution 3D images of rock sample. These images are acquired using high technology µCTscanners which are not widely available. Imaging by this technique is also expensive and time consuming. However, improvement of 3D reconstruction algorithms such as CCSIM reconstruction method made it possible to be used effectively as an alternative strategy in DRP. In this paper, we propose an alternative procedure described as follow: 1. highresolution 2D imaging, 2. dividing the image to some sub-images, 3. 3D reconstructing of subsamples, 4. segmentation of porosity and mineral phases and, 5. computing of rock physical parameters. This method was implemented Berea sandstone formation. Obtained results show that, in one hand, average values of sub-samples properties follow a consistent trend with the reference trends of the rock sample. On the other hand, these trends pass the results presented by a previous work. Permeability results, however, show bi-trending. Investigation in sub-images revealed that there are two types of pore shape and pore throat size. To overcome this problem, 2D image were resampled and more representative subimages were generated. According to these results, it can be concluded that this is a valid method where an alternative method for standard Manuscript profile

        The present paper tends to analyze the pore structure of Organic rich carbonaceous rock in 4 samples from Upper Jurassic Sargelu and 5 samples from Lower Cretaceous Garau formation using low pressure nitrogen adsorption. TOC content of Garau samples ranged between 0.64 wt% and 5.21 wt% (mean 3.2 wt%).TOC varied between 0.12 and 10.94 for Sargelu samples. XRD results shows that carbonates are the dominant minerals, followed by quartz and clay minerals. The calculated total pore volume vary between 0.6 cm3/100g to 2.5 cm3/100g with the mean values of 1.4 cm3/100g. A positive linear correlation were found between TOC content of measured samples with pore structure parameters. Due to the larger variation of TOC content this relationship was more obvious for the Sargelu samples. The calculated fractal dimension ranged between 2.45 and 2.81 emphasizing the irregular pore surface of the measured samples. Based on the result of this study organic matter content is recognized as a controlling factor for pore structure and fractal characteristics of the Garau and Sargelu samples. Manuscript profile

        To the southwest of Iran there are large reservoirs of oil and gas including Jurassic and Cretaceous carbonates, with good source rocks in the succession of the Early Cretaceous and Jurassic. The purpose of this study was to investigate the production, migration and characterization of Pabdeh, Kazhdumi, Garru and Serglu source rocks in the study area. For this purpose, burial history and one-dimensional thermal modeling in four wells and two-dimensional modeling in one section for the study area were evaluated using Openuploo software to determine the maturity of layers and hydrocarbon outflow. Comparison of measured vitrinite temperature and reflectance values with model results was used for model calibration. The results of one-dimensional modelling of the burial and thermal history in this study show that the Sergloo, Grove and Kazhdumi formations have reached maturity and have had hydrocarbon outflow, but the Pabdeh Formation has not reached sufficient maturity for hydrocarbon maturation and production. The results of migration model in the studied section show that the two Early Cretaceous and Middle Cretaceous hydrocarbon systems were separated by Kazhdumi Formation and therefore hydrocarbon migration in deeper layers of Kazhdumi was mostly lateral to Abadan plain. The hydrocarbon produced from the Kazhdumi Formation, in addition to ornithologically rearing the upper layers, migrated to the Ilam and Sarvak layers due to the general slope of the layers laterally and toward the Abadan plain. In general, the process of maturation of source rocks decreased from east to west of the study area. Manuscript profile

        The fourth dimension is one of the problems that have left the borderlines of philosophy behind and are now among the main concerns of physicists. However, the accurate background and history of this view are still clouded. The roots of the fourth dimension can be traced back to the works and ideas of some thinkers of the Middle Ages, such as Anselm, in Western philosophy, although there is no explicit reference in this regard in their works. The roots of the fourth dimension have also been found in the works of Mullā Ṣadrā in Iranian philosophical society. This paper aims to demonstrate that there are some clearly explicit statements about the fourth dimension in the works of Khwājah Naṣīr al-Dīn Ṭūsī in the Islamic world before Mullā Ṣadrā. The author has found no direct statement in this respect in first-hand sources; however, some ideas have been attributed in second-hand sources to some of the mutikallimūn of the Islamic world, including Naẓẓām, Ibn Rāwandī, and ‘Abbād, that focus on four-dimensionalism. Following a historical approach, this paper has compiled the views of these thinkers and analyzed them based on a rational approach. Manuscript profile

        The concept of free will is one of the fundamental concepts in Western metaphysical tradition. Although there are some important signs regarding the origination of this concept in Greek classical philosophy and Middle Age philosophy, it was just at the beginning of the modern period that the role of free will in the interpretation of the world was more highlighted in the thoughts of each philosopher more than those of the previous one. It seems as if the role of rational knowledge has become gradually less important in this process while the role of free will has become more significant. Inspired by Heidegger, the author has tried to strengthen his standpoint by yielding more proofs than he has offered in order to examine the development of the concept of free will. In doing so, he starts with Descartes and, by investigating the views of Espinoza, Leibniz, Rousseau, Kant, Fichte, Schelling, Hegel, Schopenhauer, and Nietzsche, aims to analyze the quality of the development of this concept, particularly the relationship between the free will and knowledge in the modern period. The purpose is to show that the significance of free will for Schopenhauer and Nietzsche is not accidental, and the preliminary contexts of such a development had been previously and gradually paved by modern philosophers. The findings of this study indicate that, unlike the previous comments and interpretations, Nietzsche’s “will to power” is not a complement to a Schopenhaurian project but, rather, a complement to German idealism.

        As technology advances, man constantly seeks to learn more about interactions among his internal organs and investigate his body’s reactions in times of illness or interventions, such as electric responses of the heart and brain to external stimuli like visual or auditory ones. Hearing a sound and assessing vital signs is one type of intervention. In this research, the effects of the sound of Quran recitation on heart and brain signals in three stages – before, at the time of, and after listening to Quran recitation – have been studied. The heart and brain signals of 50 girl students aged 19 to 24 with roughly similar religious belief levels was registered at a certain time. The objective was to study the effects of listening to Quran recitation on various characteristics, differentiate various states from one another using chaotic processing methods and statistical tests, and examine the accuracy of the results via support vector machines classification. The results show that listening to the Quran has a profound effect on interactions between heart and brain data and causes an increase in data flow between heart and brain signals based on a study of correlation dimension and fractal dimension, and a rise in the interactions between these two vital organs of the body. From a Cybernetics point of view, a rise in interactions in a bio system indicates an increase in the system’s self-organization and efficiency. Manuscript profile

        One of the important problems that has remained untouched in Sadrian philosophy is the growing block view of time. On the basis of the growing view of time is the non-existence of future, while the past and present have their fixed places. Muslim philosophers have not directly addressed this idea; however, it seems to be necessary for demonstrating some statements of Sadrian philosophers about the immateriality of sensory and imaginal perceptions and memory. When we perceive something using our senses or imagination, the perception remains in our mind exactly in the same way that it had appeared. This paper is intended to illustrate that this view is, in fact, unrelated to immateriality and, in case of admissibility of its arguments, can only prove the growing block view of time. In line with this approach, the author has critically examined the literature on this theory in pre-Sadrian philosophers, particularly Suhrawardī’s claim as to attributing the idea of the growing block to some thinkers. Suhrawardī maintains that, as each of the motions has come into existence, so the whole of the motions have come into existence, and they are together in existence. Manuscript profile

        The growing use of polylactic acid (PLA) encourages technologists to conduct extensive research into valorization of PLA waste with best quality. In general, mechanical recycling of PLA is one of the most cost-effective recycling methods. However, recycled materials are commonly used for minor applications due to the inherent thermo-mechanical degradation of the polymer during recycling, which mainly results in chain scissions and intramolecular and intermolecular transesterification reactions. Therefore, it has a negative effect on the molar mass distribution and consequently on the mechanical, thermal and rheological properties of recycled PLA. In this article, a review of recent research on the effects of mechanical recycling on the properties of PLA including structural, morphological, mechanical, rheological and thermal changes was done. Furthermore, a review of three main ways of valorization of recycled PLA including thermal modification, chemical modifications in the presence of stabilizers, chain extenders, branching agents and finally mixing with nanoadditives or with other polymers was done in order to improve the properties of recycled PLA. Moreover, due to the widespread use of natural fibers to improve the performance of PLA, the recyclability of natural fiber-reinforced PLA biocomposites was investigated. Finally, two important applications of recycled PLA in the food packaging and the 3D printing industries were discussed. Manuscript profile

        <p>The word personality refers to the uniqueness, individuality and subjectivity of the subject being studied. The measurement of such a dynamic and complex concept is considered a fundamental challenge in the field of methodology for the measurement of psychological constructs. The aim of this research is to present a new method in two different parts of personality questionnaire question analysis: a) personality questionnaire question dimensions obtained from the implementation of questionnaires on independent samples through correspondence analysis and b) question prioritization using from the network data analysis method based on the importance of questions in each dimension. To achieve these goals, 32 personality questionnaires - which cover most of the application areas of personality questionnaires - were implemented on 82,988 volunteers via web-based forms. Correspondence analysis results show that personality has two dominant dimensions that explain about 75% of personality variance. The results of network data analysis show that the important questions in different indexes are not necessarily the same and the selection of questions based on a specific index should be based on the meaning of that index, however, according to the correlation structure of the priority of questions in the index network, a general index was defined based on which questions were prioritized in two dimensions of personality. The result of the present research led to the presentation of an algorithm for selecting personality questions in personality dimensions.</p> Manuscript profile

        "Creation" is the act of God Almighty, and creativity is also His attribute, but since God created man in His own image and breathed a soul into his flower, by virtue of being the Khalifa of God, he should be ascribed to the attributes of God and the manifestation of God's names and attributes. be on the ground This research seeks to obtain a road map for the creation and creation of works of art and especially architecture by comparing the process of creation of nature from the perspective of the Holy Qur'an, and further discusses the performance of an architect in interaction with the cycle of existence and the generality of the diagram. Draw his creative process. In this way, the analytical-interpretive method has been used, and the collection of materials has been done in the library and field. At the end of this study, it shows, just as God creates a person by breathing his creative spirit into an inanimate body; Man, as his successor, breathes his creative spirit into the body of raw and inanimate materials and gives life to them, and thus art is born from man. On the other hand, creation is always done as a process, and in all stages of creation, opposing elements always exist alongside each other and have an evolutionary role for each other; A kind of diversity that all come from a current source and evolve together. In other words, it can be said: in creation; God has revealed the connection with similitude and with tension; It has given identity and personality to every element. Manuscript profile

        In this paper, problem of using the 3D beamforming method (3DBF) in a multi-input-multi-output cellular communication network (MIMO) is discussed. The network consists of a cell with multiple users, in which users are distributed based on the Poisson point (PPP) process at the cell area, which is closer to the conditions in a real mobile network. In this case, the number of users inside the cell and their location will be random. Depending on the distribution of users in the space and the difference in their distance from the base station, their elevation angles will also be different. Considering the downlink transmission and the zero-forcing (ZF) precoder in the base station, with the aim of eliminating intra cell interference, we evaluate and analyze the probability of coverage in the cell and then we obtain the best antenna tilt angle to achieve maximum probability of coverage. Using the analysis of numerical results, the accuracy of the calculations and the value of the optimal tilt angle of the antenna array are confirmed. Manuscript profile

        چكيده انگليسي Polymer 3D printing is an emerging technology that further research in this field will lead to continuous improvement of polymer 3D printing design performance, which is necessary to push the boundaries in engineering and medicine. Polymer 3D printing provides the possibility of printing low-cost functional parts with various properties and capabilities. Here, by reviewing research on materials, processes and related strategies applied for medical applications, it is presented. Research in materials has led to the development of polymers with useful properties for mechanics and biocompatibility, by tuning the mechanical properties achieved by changing the parameters of the printing process. Polymer 3D printing technologies include extrusion, sheet lamination, Vat photo polymerization, additive layer, powder-based fusion, material projection, direct energy deposition. Thermal and laser inkjet techniques are more common. The two technologies of sheet exfoliation and direct energy deposition have limited medical applications. Which enables the direct deposition of design materials for useful and customized architectures. Design strategies, such as the hierarchical distribution of materials, make it possible to balance contrasting properties. The most investigated medical applications include tissue scaffolds, dental implants, medical education, delivery systems, and drug safety devices. And finally, the challenges and obstacles of polymer 3D printing were studied. Manuscript profile

        Variations in telecommunication channels is a challenge of the wireless communication which makes the channel estimation and equalization a noteworthy issue. In OFDM systems, some subcarriers can be considered as pilots for channel estimation. In the pilot-aided channel estimation procedure, interpolation is an essential step to achieve channel response in data subcarriers. Choosing the best interpolation method has been the subject of various researches, because there is no interpolator as the best method in all conditions, and their performance depends on the fading model, signal-to-noise ratio and pilot overhead ratio. In this paper, the effect of different interpolation methods on the quality of DVB-T2 broadcast links is evaluated. A simulation platform is prepared in which different channel models are defined according to the real-world measurements. The interpolation is performed by five widely-used methods (nearest neighbor, linear, cubic, spline, and Makima) for different pilot ratios. After channel equalization by the results of the interpolator, the bit error rate is calculated as the main criterion for evaluation and comparison. The rules of selecting the appropriate interpolator in different conditions is presented. It is generally concluded that for fading scenarios close to flat fading or high pilot overhead ratio, the simple interpolators such as linear interpolator are proper choices. But in harsh conditions, i.e. severe frequency-selective fading channels or low pilot overhead ratio, the more complicated interpolators such as cubic and spline methods yield better results. The amount of improvements and differences are quantified in this study. Manuscript profile

        Human resources are the key to the success of both private and public sector organizations. In the field of human resources management, there is a need to manage the empowerment, talent and competence of people through comprehensive and systematic processes. Pathology based on information is necessary and necessary to analyze and understand more precisely the structure, interactions, procedures and methods, management styles and other elements of the solution-seeking system. This research was carried out with the aim of analyzing the human resources system of the country's long-term plans. It is necessary to always monitor the environmental changes and formulate the organization's strategies and human resource strategies based on them, and identify and manage existing and future challenges. The existence of a strategic perspective and thinking in the organization causes human resource managers and employees not to stay within the limits of the present and pay attention to distant horizons and in addition to identifying and managing the existing challenges, they also identify and manage the upcoming challenges. In order to collect the data required for the research, it was collected using interviews with experts and managers related to the field of human resources. Then, using T-test and hierarchical method, the identified injuries were analyzed. In this research, 4 dimensions of executive, political, economic and legal factors were identified as damage and finally the final model was presented. Manuscript profile

        <p>Abstract The concept of &ldquo;home&rdquo; transcends its physical existence, manifesting as an intellectual image. In essence, a house is a place to live and reach peace and comfort. The term &ldquo;house&rdquo; encompasses two distinct aspects of meaning and concept, which are different from each other. The aspect of the house meaning is an objective reality of a place where a person resides, but the concept of the house is a mental perception. Understanding the concept of home necessitates a thorough analysis of each individual's mindset regarding their living space. The purpose of this research is a comparative assessment of the home concept among 9-10-year-old children residing in Shiraz and Nojin cities. The research methodology involves content analysis utilizing argumentative analogies along with information gathering through library and documentary studies, Persian and Latin articles, and field research. By analyzing and examining thirty samples of children's drawings from these cities, it is possible to identify the similarities and differences in their mental images of the home concept. Result of this examination and analysis is anticipated several conceptual codes can be obtained. From the summation of these conceptual codes, the home concept among the children of these cities can be found, encompassing themes such as peace, comfort, comfort, security, and prosperity.</p> Manuscript profile

        The current research has been carried out with the aim of evaluating the feasibility of benefiting from one of the popular pre-primary educational approaches in the world, by exploration the philosophical foundations of Reggio Emilia educational theory and evaluating it based on the Islamic theory of action. In this regard, applying the method of conceptual analysis, linguistic analysis, and regressive logical analysis, we have deduced the basic components of the philosophical foundations of this theory and criticized them based on the Islamic theory of action. One of the results of this research is the inference of twelve philosophical components as the anthropological, epistemological, and axiological foundations of this theory, including the uniqueness and decency of children and the value of their intellectual and practical independence. In addition, the theory of Reggio Emilia has adopted a social constructivist approach to knowledge and has focused on the value of justice and democracy as its governing spirit. The results of evaluation suggest that while the Reggio Emilia educational theory has unique attributes and valuable educational advancements, it is necessary to have a careful scrutiny about it and resolve its challenging aspects before its implementation. Criticisms of this kind entail: taking a reductive approach and oversighting the spiritual essence of the child; an overly simplistic and idealistic portrayal of the child; a lack of clarity regarding realism versus constructivism, alongside potential risks of radical relativism in epistemology; as well as deficiencies in accommodating absolute and conditional values alongside the variable values in the axiological realm. To address these concerns, a reconstructive approach could entail: acknowledging an overlap relation between the spiritual and the physical dimensions, taking a balanced view on the child, positioning realism as a focal point while constructivism orbiting around it, emphasizing both absolute and conditional values, and maintaining a balanced emphasis on rationality and equity in democracy.
