Abstract: Relationship between Intellectual Capital and Productivity for Companies in Tehran Stock Exchange. In this study, the relationship between intellectual capital as an important asset and competitive advantage has been discussed with productivity of the companies for Tehran Stock Exchange. To measure companies intellectual capital, two dimensions of capital efficiency (value added intellectual coefficient and its components) and value (calculated intangible value) is taken into consideration. For doing this work Information related through the years 2009 to 2013 for these companies have been collected. Hypotheses are tested by use of panel data regression. The results shows that the value added intellectual coefficient and its components (human capital efficiency, structural capital efficiency and efficiency of capital employed) have a significant and positive relationship with productivity. Also, the calculated intangible value of the company's efficiency has a significant and positive relationship only in models with fixed effects. The effect of the calculated intangible value components and value added intellectual coefficient on firm productivity, Test results shows that the efficiency of capital employed is the only factor for affecting productivity.

The watchman route problem finds a shortest closed route in a simple polygon such that each point of the polygon is visible from at least one point along the route. So far, the best solution in time complexity for the fixed watchman route problem (i.e., shortest watchman route with given start point) is O(n^3 logn). The k-watchmen routes problem, computes a set of k watchman routes such that any point of the polygon can be seen from at least one point along one route. The goal is to‎ ‎minimize the sum of route lengths or to minimize the maximum length of the routes. This problem can have no polynomial-time and approximation algorithms . We propose the first linear-time algorithm for fixed 2- watchman‎ ‎routes inside the staircase polygon. Our algorithm computes two watchman routes‎ ‎with two specific starting points in the polygon.‎. Manuscript profile

In the geometric graph embedding problem, a graph with n vertices and a set of n points in the plane are given and we want to find a one to one mapping of f between vertices of the graph to these points. The embedding f assigns a length to each edge (u,v) of E, equal to the )Euclidean( distance between f(u) and f(v) in the plane. We wish to find an embedding of minimum length, where the total length is some of the lengths of the edges of E. This is an NP-hard problem since the traveling salesman problem is one special case of it. In this paper, we present some greedy heuristics algorithm and some heuristics algorithm with respect to the Traveling salesman problem (TSP) for embedding a free tree onto a point set on the plane with minimum total edge length.

One of the machine learning tasks is supervised learning. In supervised learning we infer a function from labeled training data. The goal of supervised learning algorithms is learning a good hypothesis that minimizes the sum of the errors. A wide range of supervised algorithms is available such as decision tress, SVM, and KNN methods. In this paper we focus on decision tree algorithms. When we use the decision tree algorithms, the data is partitioned by axis- aligned hyper planes. The geometric concept of decision tree algorithms is relative to separability problems in computational geometry. One of the famous problems in separability concept is computing the maximum bichromatic discrepancy problem. There exists an -time algorithm to compute the maximum bichromatic discrepancy in d dimensions. This problem is closely relative to decision trees in machine learning. We implement this problem in 1, 2, 3 and d dimension. Also, we implement the C4.5 algorithm. The experiments showed that results of this algorithm and C4.5 algorithm are comparable.

One of the learning methods in machine learning and pattern recognition is supervised learning. In supervised learning and in two-category problems, the available educational data labels include positive and negative categories. The goal of the supervised learning algorithm is to calculate a hypothesis that can separate positive and negative data with the least amount of error. In this article, among all supervised learning algorithms, we focus on the performance of decision trees. The geometric view of the decision tree brings us closer to the concept of separability in computational geometry. Among all the available resolution algorithms related to the decision tree, we raise the problem of calculating the rectangle with the maximum difference of two colors and implement the algorithm in one, two, three and m dimensions, where m represents the number of data features. The implementation result shows that this algorithm is competitive with the well-known C4.5 algorithm. Manuscript profile

Recognizing and determining the suitability and talent of the earth is one of the primary measures in spatial and environmental planning for physical and urban development. The aim of this research is to identify and determine the spatial distribution of suitable areas for physical development in Guilan province. Land suitability was determined by hierarchical process analysis (AHP) method and using seven natural criteria including gradient, altitude, cover, rainfall, distance from fault, rock, soil. The land suitability for physical development was divided into three large, moderate and low classes, and its zoning map was prepared. The results showed that, regardless of the protected areas and the wetland, about 62% of the study area is located in the class with a high proportion. With the consideration of other parameters, these areas can be considered for developmental planning by planners and policy makers. Manuscript profile

Despite the tremendous advances in the design of human computing systems, most of them suffer from low participation or poor quality participation and a high percentage of them fail. To a large extent, the success of these systems depends on people who really behave in the system. Because human computing systems include small units of work, and each job yields little benefit to the participants, humans display a good behavior in the system if they are well-stimulated for doing so. In this paper, this issue investigated in the Intrusion Detection Human Computation system. Our purpose of creating the stimulus for increasing of employee participation is to do their jobs carefully and effortlessly with the lowest possible cost. After selecting the appropriate stimuli for this system, we designed the mechanism of rewarding incentives. The idea behind this mechanism is to use the skill of the staff in determining their rewards. After designing this mechanism, we used the theory of games to analyze and determine the game's balance. Then, we determine the minimum possible reward for each category of work using the results obtained from the mechanism analysis based on game theory. We validate of this mechanism using game theory and the results of implementation. Designing this mechanism will increase the accuracy of respondents in answering and as a result, increase the accuracy of the human intelligence detection system in identifying new attacks and reducing their erroneous alert rates. Also, by allocating the lowest financial resources required to employees based on the analysis obtained from the game theory and managing human computing system of Intrusion Detection, encourages participants to participate in the system and, as a result, prevent the failure of the human computing system of intrusion detection.

The purpose of this study is to measure how appropriate the Zahedan city's body is for the disabled and veterans use and probably the risks and failures of that. According to the research hypothesis public buildings of Iran's cities is not suitable for the disabled and veterans' life, job and commuting. In order to test this hypothesis, the background of the effort to suit cities to the disabled and veteran needs was studied, the rules and standards of the city suitable for the disabled and veterans was searched and a theoretical framework was provided as a tool for measurement and comparison. At a later step, building condition of Zahedan was assessed and compared with scientific criteria and then analyzed. Yet to analyze data, the Weighted Sum technique for buildings was used. From the physical and managerial point of view the analytical results of this study indicated that Zahedan city is not suitable for veterans needs and generates some risks for them. Still the results of this study give recommendations for city planners and developers which contain strategies to improve criteria and physical indices, codification of law and rules and managerial plans to suit spaces for the disabled and veterans. Although this study has focused on Zahedan city, the model and process of its measurement and comparison is useful as a pretty efficient tool to suit building in other cities of Iran or the same countries.

Abstract Because of the change in demographic structure of cities, it is no longer possible to meet the needs of individuals in the simple ways of the past. During the last decade the growing population of the elderly people in Tehran has led us to meet new needs for services in different areas of the urban environment, especially the adaptation of the urban space with indicators such as security, safety, accessibility, vitality, communication, social participation and ultimately transportation for the elderly. Therefore, measures should be taken by city planners and managers. In this research, survey method was used to collect information on variables and then SPSSwin20 and LISREL8.5 softwares were used for data analysis. The statistical population is the elderly citizens of District three of Tehran that is 71199 people, which makes up about 22% of the residents of this district. In this article, we seek to answer the question of whether elderly people will be provided with urban space justice. In this regard, the results show that the correlations are greater than 0.6 and equal to 1.00. As a result, we end up that the relation of the two variables is direct. In other words, the more urban spatial justice is promoted through the discovery and analysis of appropriate urban strategies for the elderly, the welfare of the elderly will increase rapidly and strongly, and vice versa.

Delineation of wellhead protection area is an important component of groundwater protection strategies to prevent probable environmental and health hazards. In this study, besides describing the calculated fixed radius (CFR) and the numerical model methods to determine the wellhead protection area, in order to compare of the methods, were used from data of eight number of drinking water wells in Yaft Abad district of Tehran. For this purpose, overlapping rate of CFR and numerical model protection areas in GIS environment were analyzed. The overlapping results show increasing distance from the wells, the effectiveness and accuracy of CFR method decreases rapidly. In the 50 days time of travel overlay, 88 percent of the numerical model areas are captured by the CFR areas. While in the 10 years overlay, only 41 percent of the numerical model areas are captured by the CFR areas. When time, money and data are limited, the Calculated Fixed Radius method is an acceptable method only to delineate the 50 days time of travel protection areas. Manuscript profile

Of human being concerns throughout the history, was generational relations, generation difference and conflict which have drawn social reformists’ attention, persistently. Social, political, economic developments and evolution of communities and particularly industrialization, have had tangible impacts on behavioural norms of generations, that, given special requirement of youth, this behavioural difference have been proved in this generation more tangible and obvious. Saadi, during short history and anecdotes, pointing to some of these conflicts and differences, considered it natural and usual, though didn’t seek to address reasons and causes of this divide. Relying on moral teachings, he attempts to invite youth to follow the elders and use of their experiences. Defending social values and traditions, he prefers behavioural patterns of the aged. Subsequently, some Saadi’ advices and his recommendations to the youth and the aged summarized in this essay, and finally the readers will judge to what extent moral teachings belong to past didactic literature might help contemporary generations to repair generational divide.

In Persian literature, Ferdowsi’s Shahnameh has been used as the resource of many researches and an interesting subject for many literary and non-literary scholars. The special multidisciplinary structure of this masterpiece and the diversity and the extent of its narratives provide an opportunity for different interpretations using methods like historicism, discourse analysis and narratology in contemporary research arena. Searching in historical origins, this article aims at studying the way of narrative building in narratives about Rostam and Goshtasb, and they interacted in epic. The use of cyclic pattern in codification and organization of historical narratives mainly leads to the formation of narratives with mythical and epical contents that limits and transubstantiate events and historical characters in the predetermined substructure patterns. As much as the historiography method under the influence of cyclic pattern of time leads to the ambiguity of historical origins of events and characters, identification, and repetition in this method of historiography, the linear transition of events with story-like narrating ploys, provides narratives about events with different historical and temporal origins that appear to be coherent since they are formed under the domination of cyclic perception of time, and they do not transfer the whole past. For this reason, and according to neo-historicism perspective, every historical narrative is a story about the past which is not equal to the past. After matching the dual patterns of time perception with epistemology schools of history, by using discourse and narratology approaches, this article displays how the cyclic and linear patterns influence the narratives related to Rostam and Goshtasb, and their permutations.

This study aims at analyzing the structure of narratives about the first battle of the three Iranian heroes Garshasb, Sam and Rostam to define the common structural pattern in them and compare it with the myth of Indra’s fight who was the Indo-Iranian god of war, with Vitra, the evil god of drought. With this purpose, and using a structural analysis of myth, narrative segments of these heroes’ first battles will be defined and their mythemes will be compared. Then, it will be revealed how the structural patterns in these narrative are in consistent with Indra’s first and famous battle. The aforementioned battles take place in parallel with an event that is the young hero/god becomes his father’s successor by removing his authority. Thus, the result of the research suggests that there is an intertwined relationship between the fight of Indo-Iranian hero with dragon, and the elimination of the venerable status of the hero’s father. It seems that these two events are somehow the transformed forms of one another and each is the alternative for the other one. Here, there is one linking element that keeps the two sides of the equation connected like a chain, and it is the weapon of having a father, i.e. the symbol of father`s power to defeat the dragon and consequently denying the father’s authority.

Discovering the meaning, musical and aesthetic capacity of the words and the smart use of them in the content of the text is a criterion to evaluate the poet’s mental discipline. In this article, using a descriptive – analytical method, and based on formalist criticism, the role of “word selectivity” in geometrical perfection and harmony of the poems of some of the most prominent modern poets has been studied. This research reveals that most important aesthetic functions of “word selectivity” of contemporary poetry are: spacing, creating harmony and geometry in verbal texture, creating multi-layered verbal and semantic harmonies and associations, and persuasiveness. Hereby, “word selectivity” leads to consistency in the internal structure and texture of the poem, and a perfection in the geometrical and artistic system of the poem. Manuscript profile

Love is one of the most prominent concepts in Persian poetry that contains broad conceptual capacities to indirectly influence the semantic structure of the constantly transformative grounds of thought and functions of poetry. This research aims to understand whether through these transformations, the concept of love remains constant in the ever-changing semantic system or it undergoes dissociative fluctuations. Furthermore, this article tries to answer this question by approaching the poetry of different time-periods in their original form and focus on the interpretations that may arise from them. This matter gains further importance when we consider the decisive role that the concept of love plays in touching the reader’s emotions and its corresponding cultural influence throughout time. Hence, this research aims to arrive at the audience’s emotional involvement and the importance of cultural occasions by studying the concept of love in canonical works of poetry extending to different time-periods. Since the cultural occasions must correspond to their semantic parallels of the concept of love, we seek to extract these parallel meanings from the concealed concepts of Persian poetry. To arrive at these hidden components of poetry, this article views the Qualitative Content Analysis method in direct contact with thought centered content analysis. Therefore, two extensive stylistic schools of ancient and contemporary Persian poetry are studied to illustrate the semantic process that the concept of love undergoes and the scope contains some of the most important approaches of Qualitative Content Analysis such as: concealed and apparent meaning, semantic units, interpretive units, regional contents, theme and motif. This research concludes that through this process, the original semantic structure of this concept has been kept by remaining in close contact with its fundamental parallel meanings.

By the 1960s, the argument was that economic phenomena were purely economic subjects. But since the 1970s, with the revival of interdisciplinary studies, a literature has emerged that argued political factors are effective on economic phenomena. Inspired by this literature and with the focus on the first decade of the Islamic Republic's political economy, this article attempts to indicate how the five political factors, including revolution, war, political instability, political fragmentations, and ultimately the social background of government have affected economic phenomena. To doing so, firstly, this article shows how the war reduced the government's oil revenues in the decade. Secondly, it explains how political instabilities led to a reduction in foreign investment in this period. Thirdly, by emphasizing political fragmentations, it reveals how this factor led to a lack of economic consensus among political elites. Finally, it becomes clear that how the social background of the revolutionary state helped to the emergence of populist economic policies in Iran that time. All these findings show how far were the economic phenomena influenced by political factors and reflected its requirements in the first decade of the revolution. Manuscript profile

Gastrointestinal diseases are 50% of the problems and diseases that lead to death in adult horses. According to epidemiological studies, for every 100 horses per year, between 0.9 and 10 horses suffer from colic. The occurrence of colic varies between different farms and even at different times in one farm. The occurrence of colic seems to be strongly influenced by the level of quality of herd management and horse maintenance throughout the year. This means that variation in the rate of occurrence originates more from management than from the breed of horses. Various factors such as breed, age, sex, history, nutrition, activities, infectious and parasitic problems and dental problems can increase the risk of colic in horses. For example, Arabian horses have been identified as predisposed to colic, and other Heidegger breeds such as the Thoroughbred and Warmblad, and standard-range horses, are at high risk for colic. In addition, stallions, especially castrated stallions, are more susceptible to colic. Changes in the type of concentrate consumed, the type of other feeds, the quality of forage and pasture are closely related to colic and their causative agents. Intestinal parasites, especially tapeworms and streptococci, are important risk factors for colic that can increase the risk Manuscript profile

Veterinary anesthesia is a relatively new science that uses different drugs and techniques to provide optimal condition (analgesia, immobility, muscle relaxation and amnesia) to perform various medical, diagnostic and surgical procedures in domestic, exotic and wild animals. In order to perform a safe sedation, analgesia, local and general anesthesia, adequate scientific knowledge of anatomy, physiology and pharmacology of the species are required. The most common species that referred for surgical procedures are small animal (cat and dog) and horses. Although surgical procedure are also performed on ruminants, general anesthesia is not common in these species due to some specific reasons (economic costs, bloat, regurgitation and easily performed standing surgeries in cattle). There are several anatomical, physiological and pharmacological differences as well as difference in body weight and temperament between small animal and horses that should be considered before anesthesia. The present paper discusses the major differences that require appropriate preoperative preparation when conducting anesthesia in small animal and horses. Manuscript profile

The movement of the workforce between the formal and informal sector can change the face of the cities and affect the development of the country. One of the main reasons for the recruitment of informal labor in various industries is to escape tax policy of the state. The study of the impact of government tax policies on the development trend of different regions of the country (especially developing countries) is significant for policy makers. In this paper, we have tried to use a generalized computable equilibrium model (CGE) to examine the impact of government tax policies on the economy of Qazvin province. The result of this study reflects the fact that the increase in taxes will lead to a strong movement of labor from the official sector to the informal sector in the province. Manuscript profile

Society requires a variety of elements for its consistency and durability, including respect for high human and moral values. As these values, grow from the context of society; in all societies, both traditional and modern, they will have their place, some values including respect for the rights of others, self-respect, self-sacrifice, and so on. Not all societies are valuable, and others are valued for the attitude of each community and its culture, but not all of these values have the same guarantee, and given the importance of these principles, they offer poor guarantees such as condemnation. To a greater extent, there are legal penalties that this article considers the observance of the lasting values in the Supreme Audit Court and examines this. And this, whether in the absence of compliance with these principles and human moral values executive guarantee considered legal or not? In other words, do the Supreme Audit Court employees face legal guarantees if they violate ethical values? We have come to an analytical conclusion that violating certain ethical values in laws such as the law of the supreme audit Court, the law of public accounting and the law on dealing with administrative offenses, etc. has legal guarantees and even severe punishments including dismissal and ...

The findings of the study indicate that Imamite Shiites, who enjoyed relative comfort and government authority during the reign of The Buyid dynasty, experienced a hard time following the Sunni Seljuks' invasion of Baghdad and the overthrow of The Buyid dynasty. The Seljuks expelled them from office; their religious leader, Sheikh Tusi, was forced to leave Baghdad and was attacked by the Sunnis after the suppression of the Shiite rebellion in the city of Karkh. But the circumstances did. The present study discusses not last the Shiites gradually regained their positions of power. The current paper discusses the interaction between the Shiites‎ and the caliphate, the knowledge of scientific and cultural activities and developments, and how Shiites were involved in important government affairs in the Seljuk era taking into account the presence of Shiite rulers and ministers in Iran. The time span of the current paper dates back to approximately the beginning of the fifth century (485-430 AH), the period of Seljuk rule in Iran. This is a descriptive-analytical study using documentary and library sources to investigate the relationships and interactions of Imamite Shiites in Iran under Seljuk reign Manuscript profile

Knowledge-based economy is modern economy that production and distribution is based on knowledge and knowledge itself is the main source of growth and wealth creation. Knowledge-based companies are generators of knowledge-based economy. Knowledge-based companies & institutions are private or cooperative companies that cause synergy of science and wealth, development of knowledge-based economy, achievement of scientific and economic goals (including development and application of invention and innovation) and commercialization of research and development (including design and production of goods and services) in the high technology and high value-added production, particularly in the form of software. Knowledge-based companies can be divided into two categories: micro and macro. K-based companies have made some important features such as job creation, positive competitiveness, generation and development. Those companies are commensurate with their growing economies. Organizational structures of companies in many different companies and organizations are playing an efficient role. The types of organizations and companies determine organizational structure. In this study we reviewe organizational structures, including functional, productional, regional, Matrix, connectional, horizontal, network, associational, star, clover and Virtual. We propose a suitable pattern “network-Virtual-horizontal” for organizational structure of K-based companies. This organizational structure increases productivity in knowledge-based companies.

Paying attention to the position and role of knowledge-based companies in advancing the country's economic and social goals is very important. On the other hand, the issue of dynamism and market turbulence in today's markets makes it even more important to pay attention to these businesses. The knowledge-based companies are based on innovation in business. However, the turmoil in markets and competition makes it important to pay attention to the dimensions of innovation strategies in different environmental conditions, and the business of students who do not consider innovation in line with environmental conditions may fail in innovation and will not perform well. The aim of this study is to investigate the strategic relationship between innovation strategies and business performance with the role of moderating market turbulence and environmental dynamics. The statistical population of this study includes 115 knowledge-based companies in East Azerbaijan province. In order to analyze the data, structural equation modeling method was used and the hypotheses were analyzed using AMOS software. The results showed that product innovation and process strategy have a positive relationship with business performance. However, the modification test results showed that process innovation performs better in high environment dynamics and product innovation in high market turbulence. Manuscript profile

The right to food is one of the basic and fundamental rights for every person. In order to be able to benefit from other rights, people’s nutritional needs must first be satisfied. Without securing and attending to this right and innate need, a human will not be able to live and benefit from the rest of human rights. The right to food is not a separate and distinct topic, it's one of the subsets rights of economic and social rights that are recognized under the title of right to adequate standards of living including right to food. The result of this research shows that in addition to the universal importance of right to food and nutrition, children’s nutrition is more important because of their age and health status. Child nutrition as well as other rights, particularly right to education is very closely related. These are the things that turn the right to food into one of the most important human rights that requires attention, infringement on which should be followed up and investigated. Manuscript profile

“Gushtasb” the Kiani's king announces that his condition for giving power to his son “Esfandiar” is arresting of “Rostam”. Rustam kills Esfandiar in a battle. Before dying, Esfandiiar ask Rustam to teach his son, Bahman, the royal and martial arts. Later, Bahman returns to his grandfather and at this time, Gushtasb calls “Jamasb” and tells him that he intends to step down from his monarchy and then died. The purpose of the present study is to investigate how power is transferred from "Gushtasb" to "Bahman". This article examines the events that took place after Esfandiar's death which were recorded in various sources. The events is show that "Gushtasb" was ousted in a public uprising by the royal family and under Bahman's supervisor. For the Sassanid kings who extended their ancestry to the Kiani's Bahman and their government widely supported Zoroastrianism, as well as their religious leaders, it was not pleasant that the others read the story of a coup against Gushtasb. Therefore, they have deliberately sought to demonstrate that it was a peaceful power transition. Manuscript profile

Logicians view both aposteriori and apriori methods of reasoning as arguments. However, the question is whether both of them enjoy equal levels of validity, and whether both attain logical certitude. Based on the principle of “the possessors”, stating that the knowledge of existents which have a cause can only be attained through the knowledge of their cause, Ibn Sina maintains that only the apriori argument, which attains perfect certitude, enjoys logical validity, while the aposteriori argument lacks validity since it does not attain logical certitude. However, he considers the aposteriori argument to be valid and a tool for attaining certainty through general concomitants. Unlike Ibn Sina, Mulla Sadra views all aposteriori arguments to be valid because, in his view, the existence of the effect certainly indicates the existence of the cause. As a result, the knowledge of the existence of the effect leads to the knowledge of the existence of the cause. This paper demonstrates that Ibn Sina’s idea in this regard is justified, while that of Mulla Sadra is illogical and unacceptable because of its inconsistency with well-established logical principles.

In this paper a novel technique for automatic data clustering based on the artificial immune algorithm is proposed. The lengths of the antibodies are dynamically changed based on inter-clusters and intra-clusters distances by means of a fuzzy controller which has been added to the immune algorithm to provide, also, a soft computing approach for data clustering. This idea leads to proper number of clusters and effective and powerful clustering process without any additional try and error efforts. Also the manual setting of the number of clusters is available in the proposed algorithm (like other unsupervised clustering approaches) after removing the fuzzy controller from the proposed clustering system. The method has been tested on the different kinds of the complex artificial data sets and well known benchmarks. The experimental results show that the performance of the proposed technique is much better than the k-means clustering algorithm (as a conventional one), specially for huge data sets with large feature vector dimensions. Furthermore, it is found that the performance of the proposed approach is comparable, sometimes better than the genetic algorithm based clustering technique (as an evolutionary clustering algorithm).

This paper defines an optimal architecture for the FPGA using exact methods. In order to achieve this goal, optimal placement and routing solutions are found using the integer linear programming techniques. After redefining the internal architecture of the logic blocks, quantum circuits are partitioned by a heuristic algorithm in order to reach maximum utilization of the resources inside logic blocks and minimum delay of the paths traversed by the q-bits in the circuit. Experimental results show that FPGA architecture modifications can result in the reduction of the delay of critical paths of circuits by up to half in some cases and in a considerable reduction of the number of channels used for routing. Furthermore, the results show that defining the logic blocks with 12 q-bits instead of 4 q-bits can decrease circuits delay and the number of used channels to a large extent. Manuscript profile

In this paper, we present a new efficient method based on local binary pattern descriptor, for face recognition. Because, the calculations in Local binary pattern are done between two pixels values, so, small changes in the binary pattern affect its performance. In this paper, a new local average binary pattern descriptor is presented based on cellular learning automata and evolutionary computation (CLA-EC). In the proposed method, first, the LABP operator are used to extract uniform local binary patterns from face images; it should be noted that, in LABP operator to obtain more robust feature representation, many sample points has been used. Then, the best subset of patterns found by CLA-EC methods, and the histogram of these patterns is obtained. Finally, support vector machine is used for classification. The results of experiment on FERET data base show the advantage of the proposed algorithm compared to other algorithms. Manuscript profile

Separating colored point sets is an interesting problem in computational geometry with application in machine learning and pattern recognition. In this problem, we are given a geometric shape C and two point sets P and Q of total size n as red and blue points, respectively. Now, we must separate red and blue points by this shape such that all the blue points lie inside it and all the red points lie outside it. In the previous work, we have some algorithms for rectangle and wedge separability but we do not have any algorithm for separating by a triangle and separating by a triangle with a fixed angle such as right triangle. In this paper, we present an efficient algorithm for right triangle seprability. In this algorithm, we use sweep line technique and introduce some events and process them. So, we can report all separating right triangles in O(nlog n) time. Manuscript profile

Today, botnets are known as one of the most important threats against Internet infrastructure. A botnet is a network of compromised hosts (bots) remotely controlled by a so-called botmaster through one or more command and control (C&C) servers. Since DNS is one of the most important services on Internet, botmasters use it to resistance their botnet. By use of DNS service, botmasters implement two techniques: IP-flux and domain-flux. These techniques help an attacker to dynamically change C&C server addresses and prevent it from becoming blacklisted. In this paper, we propose a reputation system used a clustering method and DNS traffic for online fluxing botnets detection .we first cluster DNS queries with similar characteristics at the end of each time period. We then identify hosts that generate suspicious domain names and add them to a so-called suspicious group activity matrix. We finally calculate the negative reputation score of each host in the matrix and detect hosts with high negative reputation scores as bot-infected. The experimental results show that it can successfully detect fluxing botnets with a high detection rate and a low false alarm rate. Manuscript profile

Then, we solving this model by using the PROMETHEE method, which is one of the most widely used method for MADM problems. In this method, selecting the best VM occurs based on the value assigned to each of criteria which is calculated based on fuzzy logic. To evaluate the performance of this approach, the necessary simulations have been carried out on CloudSim simulator and shown that the proposed method has better performance compared to FIFO, DLB and WRR methods on average in terms of response time, rate of success tasks, load variation and rate of VM migration.

Quantum-logic synthesis refers to generating a quantum circuit for a given arbitrary quantum gate according to a specific universal gate library implementable in quantum technologies. Previously, an approach called block-based quantum decomposition (BQD) has been proposed to synthesize quantum circuits by using a combination of two well-known quantum circuit synthesis methods, namely, quantum Shannon decomposition (QSD) and cosine-sine decomposition (CSD). In this paper, an improved block-based quantum decomposition (IBQD) is proposed. IBQD is a parametric approach and explores a larger space than CSD, QSD, and BQD to obtain best results for various synthesis cost metrics. IBQD cost functions for synthesis are calculated in terms of different synthesis cost metrics with respect to the parameters of the proposed approach. Furthermore, in order to find optimum results according to these functions, IBQD synthesis approach is defined as a constrained-optimization model. The results show that IBQD can lead to the minimum total gate cost among all the proposed approaches for the specific case of 4-qubit quantum circuit synthesis. Moreover, for the first time, the depth costs of the CSD, QSD, BQD, and IBQD synthesis approaches are evaluated and it is shown that IBQD makes a trade-off between the total gates and depth costs for the synthesized quantum circuits.

A fundamentally quantum model of computation based on quantum entanglement and quantum measurement is called one-way quantum computation model (1WQC). Computations are shown by measurement patterns (or simply patterns) in this model where an initial highly entangled state called a graph state is used to perform universal quantum computations. This graph together with the set of its input and output qubits is called the geometry of the pattern. Moreover, some optimization techniques have been introduced to simplify patterns. Previously, the 1WQC model has been applied to optimize quantum circuits. An approach for parallelizing quantum circuits has been proposed which takes a quantum circuit and then produces the corresponding pattern after performing the proposed optimization techniques for this model. Then it translates the optimized 1WQC patterns back to quantum circuits to parallelize the initial quantum circuit by using a set of rewriting rules. To improve previous works, in this paper, a new automatic approach is proposed to optimize patterns based on their geometries instead of using rewriting rules by applying optimization techniques simultaneously. Moreover, the optimized pattern is translated back to a quantum circuit and then this circuit is simplified by decreasing the number of auxiliary qubits. Results show that the quantum circuit cost metrics of the proposed approach is improved as compared to the previous ones. Manuscript profile

The grid tied PV systems without transformer have some benefits such as low cost, weight and size and also increases the overall efficiency. The galvanic connection between the grid and PV system causes leakage current in the transformerless inverter to flow through parasitic capacitors between the PV system and ground and causes personal safety problems, increases the output harmonic spectrum, and system losses. This paper introduces a modified single phase two stage transformerless inverter for grid connected photovoltaic systems with low leakage current. The neutral of the grid is directly connected to the negative terminal of PV panel that eliminates leakage current without complex control strategy. In this paper, a Proportional Resonant (PR) control strategy is used to control the injected current. The performance of the transformerless inverter is analyzed and its structure has been simulated in PSCAD/EMTDC and the obtained results tested experimentally. Manuscript profile

Wireless sensor networks have limitations such as processing power, storage resources, and time delay in data transfer to the cloud. The cloud computing by the development of cloud-based services to the edge of the network reduces traffic and delays, so these types of networks are used in many systems, such as medical care, wearable devices, transportation systems and smart cities. Task scheduling techniques in fog computing are considered to be NP-hard issues. Applications require resources to run. Network fog devices are close to the sensors and the cloud and have the required processing power to run the applications. Each fog device can be used to run resource allocation policies. In this paper, we present an optimized Knapsack-based method optimized by symbiotic organism search to allocate resources appropriately to tasks in fog network. The proposed method is simulated in the iFogsim as a developed library from Cloudsim for fog computing. The results indicate improvement in energy consumption, resource consumption, and execution cost of the network. The proposed method is better than FCFS and Knapsack methods. Manuscript profile

One of the major challenges and constraints in designing very large integrated circuits is the power dissipation of transistors. Reversible logic is one of the new paradigm in reducing the power consumption of digital circuits in the quantum computing field. In this paper, an improved design of a parallel 5-bit parity preserving reversible signed multiplier circuit is presented. Reversible circuit designs with parity preserving property are an important issue for the implementation of fault tolerant systems in nanotechnology area. To design of the proposed multiplier, the reversible full adder circuit using 5×5 reversible HBF block with low quantum cost, and the 4×4 reversible HBL gate, with parity preserving property are proposed. The structure of the multiplier circuit consists of two parts of the partial product generation (PPG) and multi-operand addition (MOA). This structure is based on Baugh-Wooley and Wallace-Tree algorithms, which results in improved speed of operation in a 5-bit multiplier for signed digits. The proposed circuits are optimized based on important evaluation issues such as quantum cost, garbage outputs and constant inputs, and also are compared with the existing circuits. The main goal is to reduce the quantum cost, the number of constant inputs and garbage outputs in the design of the proposed multiplier circuit. The results of the final evaluation and comparison shows that the proposed multiplier in this study is improved by 26% in quantum cost, 9% in garbage outputs and 9% in constant inputs relative to the best existing designs.

Wireless sensor networks (WSNs) consist of thousands of small nodes. The small and inexpensive parts of these nodes have led to their widespread use in various fields. However, these networks have constraints on energy consumption, processing resources, and storage which have caused many studies to find solutions to reduce these constraints. In recent years, with the advent of the concept of Fog computing, many new and effective solutions are represented for routing in wireless sensor networks. Since in WSNs it is important to save alive nodes and reduce the energy consumption of nodes, fog computing is useful for this purpose. In most WSN routing protocols, the best way to send data to cluster heads and the base station is the major part of their studies. In the new protocols, the Fog computing have been used to find the best way. In these methods, we have seen decreasing energy consumption and increasing network lifetime. In this paper, we represent a fog-based algorithm for routing in WSNs.

Mobile edge computing (MEC) are new issues to improve latency, capacity and available resources in Mobile cloud computing (MCC). Mobile resources, including battery and CPU, have limited capacity. So enabling computation-intensive and latency-critical applications are important issue in MEC. In this paper, we use a standard three-level system model of mobile devices, edge and cloud, and propose two offloading and scheduling algorithms. A decision-making algorithm for offloading tasks is based on the greedy Knapsack offloading algorithm (GKOA) on the mobile device side, which selects tasks with high power consumption for offloading and it saves energy consumption of the device. On the MEC side, we also present a dynamic scheduling algorithm with fuzzy-based priority task scheduling (FPTS) for prioritizing and scheduling tasks based on two criteria. Numerical results show that our proposed work compared to other methods and reduces the waiting time, latency and system overhead. Also, provides the balance of the system with the least number of resources. And the proposed system reduces battery consumption in the smart device by up to 90%. The results show that more than 92% of tasks are executed successfully in the edge environment. Manuscript profile

As technology nodes shrink below 90 nm, high static power consumption has become one of the biggest problems of CMOS based circuits due to the exponential leakage current of transistors. Spintronic devices such as magnetic tunnel junction (MTJ) due to their fascinating features such as low static power consumption, non-volatility, high endurance, compatibility with CMOS transistors and high-density fabrication are one of the promising candidate for designing hybrid MTJ/CMOS circuits and overcoming high static power consumption of CMOS based circuits. In this paper, a fully nonvolatile and low power hybrid MTJ/CMOS full-adder circuit for Realization of Process in Memory is proposed. The simulation results show that all the proposed circuit is at least 50% faster than all previous counterparts, the power output delay is 39% lower than the previous design, and does not impose high hardware overhead.

In one-way quantum computation model (1WQC), the quantum correlations in an entangled state, called a cluster state or graph state, are used to perform universal quantum computations using single-qubit measurements. In 1WQC, the computations are shown by measurement patterns or simply patterns. The synthesis problem in the 1WQC model is defined as extracting the pattern from a given arbitrary unitary matrix. The important criteria in evaluating measurement patterns in the 1WQC model, are the size, the depth and the number of entanglements of the pattern. In this paper, a new approach is proposed to synthesize controlled-unitary U gates where U is a single-qubit gate. To this end, for the first time, the idea of applying the extended measurement calculus, which utilizes the measurements in different Bloch sphere planes, is used in the synthesis of the 1WQC model. Some optimizations are proposed for this method and a new approach is presented to synthesize controlled-U gates for the 1WQC model which improves the evaluation criteria of size, depth and the number of entanglements in this model as compared to the best previous result by 9.1%, 30% and 18.1%, respectively.

VLSI technology is currently dealing with a serious challenge, as the exponential growth of density in VLSI and CMOS chips has reached its limit. Power dissipation in VLSI chip refers to heat generation, which is a real barrier against traditional CMOS technology. Irreversible logic leads to problems such as energy dissipation, heat generation, information loss and slow computations. We need a new technology for solving these problems. Using reversible logic can help solve this problem. In next generation of optical computers, electrical circuits and wires will be replaced by several optical fibers and these systems will be more efficient because they will be cheaper, lighter, and more compact without interference. Based on optical computations, several optical switches have been proposed for future applications. One of these switches is the Mach-Zehnder switch. Its behavior and the reversible circuits, which can be made with this switch is studied in this article. Finally, we introduce and design three new all-optical reversible gates named NFT, SRK and MPG, which are effective in designing all-optical reversible logical circuits such as flip-flops and other all-optical reversible sequential circuits. We also simulate one all-optical reversible circuits implemented with Mach-Zehnder switch and provide simulation challenges and solutions to overcome these challenges. Manuscript profile

The efficiency of human action recognition systems depends on extracting appropriate representations from the video data. In recent years, deep learning methods have been proposed to extract efficient spatial-temporal representations. Deep learning methods, on the other hand, have a high computational complexity for development over temporal domain. Challenges such as the sparsity and limitation of discriminative data, and highly noise factors increase the computational complexity of representing human actions. Therefore, creating a high accurate representation requires a very high computational cost. In this paper, spatial and temporal deep learning networks have been enhanced by adding appropriate feature selection mechanisms to reduce the search space. In this regard, non-online and online feature selection mechanisms have been studied to identify human actions with less computational complexity and higher accuracy. The results showed that the non-linear feature selection mechanism leads to a significant reduction in computational complexity and the online feature selection mechanism increases the accuracy while controlling the computational complexity.

In imprecision-tolerant applications such as image processing and machine learning, imprecision can be tolerated because of the nature of the application itself or the limitation of human senses. By using the approximate computation in these applications, significant power, delay, or area reductions can be achieved. In this paper, two approximate full adders and an approximate adder, with low error are proposed. The effects of die-to-die (D2D) process variation on the threshold voltage of approximate circuits have been evaluated. For evaluating the accuracy and the variability, these approximate full adders have been used and analyzed in the ripple carry adder structure, image Sharpening and image Smoothing algorithms. In terms of power-delay-product (PDP), accuracy, and area for uniformly distributed inputs, the proposed approximate full adder 1, exhibits the best performance, and the proposed approximate full adder 2 and the proposed approximate adder, show the best peak-signal-to-noise ratio (PSNR) for real images.

Resilience in power systems refers to the system's ability to withstand severe disturbances with a low probability of occurrence. Because in recent years extreme dust storms have caused severe damage to Iran's electricity industry, especially in the south and southwest, in this paper proposed a new scenario-based stochastic planning model for enhancement of power distribution systems resilience against extreme dust storms. In proposed model, in the first stage, the investment costs to improve the distribution system resilience against extreme dust storms are minimized due to the financial constraints, and in the second stage, the expected operating costs in dust storm conditions are minimized due to the operating constraints. Because network's insulation equipment are major cause of distribution system vulnerabilities in the dust storms, measures in the planning stage include replacement of porcelain insulators with silicon-rubber type, installation of automatic tie switches and installation of emergency generators. In the second stage, the measures are divided into preventive actions and corrective actions, and coordination between stages 1 and 2 is implemented in such a way that the results of each stage depend on the decision variables of the other stage. The simulation results for IEEE 33-bus test system and a 209 bus radial distribution network located in Khuzestan province, Iran, confirm the efficiency of the proposed model in different financial conditions.

Soft computing techniques in engineering sciences have covered a large amount of research. Among them is the design and optimization of navigation systems for use in land, sea, and air transportation systems. Therefore, in this paper, an attempt is made to take advantage of novel approaches of intelligent metaheuristic optimization for designing integrated navigation systems. For this purpose, the inclined planes system optimization algorithm with several modified and new versions have been used along with two well-known methods of genetic algorithm and particle swarm optimization. Considerations are made on an INS/GNSS problem with IMU MEMS inertia measurement modules. Process and measurement noise covariance matrices are considered as design variables and the sum of mean-squares-error as an objective function in the form of a single-objective minimization problem. Outputs are presented in terms of statistical and performance indicators such as runtime, fitness, convergences, angular-velocity accuracy, latitude, longitude, altitude, roll, pitch, yaw, and routing along with the ranking of algorithms. The overall assessment indicated the correctness of the performance and the relative superiority of the IPO and IIPO over the competitors and competitive performance of the assumed algorithms in comparison with the volume of considerations and calculations of the base problem.

The two phenomena of wound contraction and reepithelialization which occur as stages of the repair phase in healing of the wound play an important role in closing the damaged site. Contraction is formed by the transformation of the modified fibroblast cells called myofibroblasts, and these cells, through their tensile properties, pierce the wound's environment and cut the edges together, and after contacting the two healthy regions, this process stops. Epithelialization also covers the damaged area by migrating epithelial cells at the wound surface. These cells, by secretion of the enzymes, open their path of movement on the wound surface and, after reaching the same cells, stop and thus the location of the ulcer is covered and problems such as fluid loss and the entry of microbial objects to the body will be disappeared.

The role of general and specific blessing of Imam Zaman should also be seen in a network of divine traditions; That is, the Imam plays a role in this system. According to the same system, in repelling or eliminating calamity, material causes must be used first; However, the function of material objects in repelling or eliminating the cause of spiritual calamity is not permanent and comprehensive; Secondly; The influence of spiritual factors is realized in the form of conditional and absolute law, in the former of which the existence of a condition and in the latter of the existence of expediency are central, and the role of His Holiness must be seen in this form.

Quantum computing is a new method of information processing that is based on the concepts of quantum mechanics and leads to strange and powerful events in the quantum field. The logic synthesis of quantum circuits refers to the process of converting a given quantum gate into a set of gates that can be implemented in quantum technologies. The most famous logic synthesis methods are CSD and QSD. The main goal of this study is to present a multi-objective logical synthesis method combining the above two methods in the quantum circuit model with the aim of optimizing the evaluation criteria. In this proposed method, the solution space is created from different combinations of CSD and QSD decomposition methods. The created solution space is a space with a very large exponential size. Then, using a bottom-up approach of multi-objective dynamic programming, a method is presented to search only a part of the entire solution space to find circuits with the optimal Pareto costs. The obtained results show that this method creates a balance between the evaluation criteria and produces many optimal Pareto solutions that can be selected according to different quantum technologies.

Among the flexor tendons in the horse's limbs, the superficial digital flexor tendon is more prone to damage than the deep digital flexor tendon. SDF tendonitis is a common injury in event horses. Recovery of superficial digital flexor tendon (SDFT) injuries is slow, but re-injury is likely. SDF tendon injuries are more common in the forelimb. Flexor tendon injuries are due to strain on the tendon or a direct trauma. Tendon damage vary from inflammation and pain to complete rupture of the tendon. Injuries caused by strain are associated with swelling that require ultrasound assessment to confirm the diagnosis. Treatment for these injuries includes anti-inflammatory treatment, which is initially followed by a rehabilitation program. In cases where drug treatment is not responsive, surgical procedures including tendon splitting and superior check ligament desmotomy can be used. In this study, we briefly review the tendonitis of the superficial digital flexor tendon, etiology, clinical signs, diagnosis, treatment and prognosis. Manuscript profile

Tendon sheath is a connective tissue that main function is to protect the tendon in the areas that are most vulnerable to damage. One of the relatively common causes of lameness and abnormalities in the limb of horses is tendon sheath damage. Injuries to the digital tendon sheath, tarsus, and carp are more common than tendon sheaths in other parts of the limbs. Lameness and swelling at the site of the lesion are common clinical findings in many tendon sheath injuries. Primary diagnosis of tendon sheath inflammation is possible with the help of animal history and clinical signs. The use of diagnostic tools, especially diagnostic imaging, is very useful for definitive diagnosis and identifying the primary cause of the disorders or damage to the surrounding tissues. Complete treatment should be done after identifying the underlying cause of sheath inflammation, although treatments such as rest, the use of anti-inflammatory drugs, and cold therapy are effective in reducing inflammation and improving clinical signs.

Nowadays, quantum computing has played a significant role in increasing the speed of algorithms. Due to the limitations in the manufacturing technologies of quantum computers, the design of a large-scale quantum computer faces many challenges. One solution to overcome these challenges is the design of distributed quantum systems. In these systems, quantum computers are connected to each other through the teleportation protocol to transfer quantum information. Since quantum teleportation requires quantum resources, it is necessary to reduce the number of that. The purpose of this paper is to present a distributed quantum system considering the two goals of balanced distribution of qubits and minimizing the number of teleportation protocols in two levels. In the first level, by presenting a dynamic programming algorithm, an attempt has been made to distribute qubits in a balanced manner and reduce the number of connections between subsystems. According to the output partitioning obtained from the first level, in the second level and in the stage of implementation of global gates, when one of the qubits of this gate is teleported from the home to the desired destination, this qubit may be able to be used by a number of global gates, observing the precedence restrictions and as a result it reduces the number of teleportations. The obtained results show the better performance of the proposed algorithm. Manuscript profile

The main purpose of this paper is to examine the historical discourse of the birth of the modern school in terms of power relations around the lives of children. The method used in this essay is Critical Discourse Analysis of Michel Foucault. In order to achieve the purpose of the study, the formation of new schools is analyzed from Foucault's point of view and his commentators. According to this description, a transformation has occurred from a body-based abstinence to institutional development of child care and school development. The most important discourse developments include the advent of modern childcare practices, the concealment of punitive care around children, and ultimately the expansion of modern power over the child's soul. Then, the power relations were analyzed based on a documentary analysis of the discursive approach to childhood and education. The results show that the birth of modern school and different branches of knowledge such as child psychology and sociology that shaped educational knowledge were the result of the evolution of the underlying social, economic, and demographic policies and disciplinary technologies and did not necessarily lead to the freedom of children. Therefore, the lives of children depend on the liberation not from institutions, but from the domination systems. Manuscript profile

Objective (s): From a single cell to a few-months old embryo we can witness an extremely precise and subtle process displaying an interesting phenomenon with stunning intricacies. The study of this Phenomenon is called “embryology”. Through the advancement of science, man has managed to uncover some of the mysteries of creation of embryo and understand some parts of the process. However, many aspects of creation of embryo are still mysterious and unknown to man. It can be assured that embryo is a being with various mysteries and enigmas and that discovering the remarkable interrelationships between the limbs and systems in embryo can demonstrate the greatness of God’s creation. When one meticulously examines the complex and intricate phases of creation of embryo, which begins from a single and seemingly insignificant cell and following its phases of development turns into the feat of creation, he will definitely bow humbly before God’s Throne of Grace and acknowledge the greatness of creation and the power of the Almighty. Method: The method used for this research is descriptive – analytical. Conclusion: 1. The Quran has classified the stages of embryo’s development with a unique and simple language in a way that it was understood at the time of revelation, and its accuracy can be verified now and in the future. 2. The Quran with special subtlety describes the complex system of creation, development and evolution of embryo in a way that can be defended by today’s science. 3. The Holy Book’s referring to sperm as the first stage of embryo’s creation is com partible with man’s findings in embryology today. Manuscript profile

Places of worship, especially mosques, are considered one of the richest platforms for the evolution and exaltation of the human spirit and possess great significance. The geometry of these buildings is considered one of their common and regular features, having specific proportions and rules. Also, it has created an intangible heritage identity for the contemporary era. Knowing and interpreting these proportions can play an important role in repairing and reusing the historic building, using them in future architectures, and elevating the new architecture. This research aims to discover similarities and differences between cultural platforms from the Timurid to Safavid eras by reviewing the principles and proportions using geometric analysis. To identify the mathematical relationships of the architectural body of mosques' courtyards and understand their geometrical proportions, this research has used the combined method of historical interpretation based on valid evidence and logical reasoning of the mathematical type. Based on this, the sides and proportions of the courtyards and constituent parts of 9 Timurid, Safavid, and Qajar mosques have been subjected to numerical analysis based on Euclidean-longitudinal calculations and the scale of proportions in the courtyard plan of the mosques. Findings of this research indicate that the geometry of the courtyard and components of the discussed mosques have employed golden proportions, and Mahtabi halls attached to the mosque courtyards during the Safavid period have been developed in the same proportions through the Qajar period.

The central yard, as an efficient and responsive device, has done its job well in protecting residents from environmental, social and cultural conditions in different regions of Iran. The physical typology of the central courtyard in different regions of the country, especially the buildings related to the first Pahlavi period, is a topic that this research seeks to answer. For this purpose, traditional houses with courtyards from different cities of the country have been selected as study samples. This research aims to investigate the physical structure, patterns and various types of the central courtyard in traditional houses, to study the typology of these houses. In order to carry out the research, more than 60 examples of traditional houses in the historical area of different cities of Iran were identified and 23 houses that had complete information and documents were selected for classification. According to their nature, research data has been collected by referring to library sources and field observations. The results of the classification of the location of the courtyard in the building show that one construction front (with the building mass on the northern side of the courtyard) has the most and buildings with two courtyards on both sides of the building have the lowest frequency among the samples studied. Also in In the longitudinal classification, 15.1-25 has the highest frequency, while in the transverse classification, the maximum frequency belongs to 15.1-20. Yards with an area of 100 to 400 square meters have the highest frequency among the samples studied. In the classification of proportions, the highest frequency is related to the proportions of 1.1 and the lowest is related to 1.5, which indicates the stretching of the yards towards the square. After the classification and comparison, Tousizadeh house has been chosen as the representative of the species with the highest abundance and Ganjalizadeh house as the representative of the species with the least abundance in the study context.

Mobile edge computing improves the experience of end users to achieve appropriate services and service quality. In this paper, the problem of improving resource allocation when offloading tasks based on mobile devices to edge servers in computing systems was investigated. Some tasks are processed locally and some are offloaded to edge servers. The main issue is that the offloaded tasks for virtual machines in computing networks are properly scheduled to minimize computing time, service cost, computing network waste, and the maximum connection of a task with the network. In this paper, it was introduced using the hybrid algorithm of particle swarm and gray wolf to manage resource allocation and task scheduling to achieve an optimal result in edge computing networks. The comparison results show the improvement of waiting time and cost in the proposed approach. The results show that, on average, the proposed model has performed better by reducing the work time by 10% and increasing the use of resources by 16%. Manuscript profile

Fog computing technology has emerged to respond to the need for modern IoT applications for low latency, high security, etc. On the other hand, the limitations of fog computing such as heterogeneity, distribution, and resource constraints make service management in this environment challenging. Intelligent service placement means placing application services on fog nodes to ensure their QoS and effective use of resources. Using communities to organize nodes for service placement is one of the approaches in this area, where communities are mainly created based on the connection density of nodes, and applications are placed based on a single-criteria prioritization approach. This leads to the creation of unbalanced communities and inefficient placement of applications. This paper presents a priority-based method for deploying applications in the fog environment. To this end, balanced communities are created and applications are placed in balanced communities based on a multi-criteria prioritization approach. This leads to optimal use of network capacities and increases in QoS. The simulation results show that the proposed method improves deadline by up to 22%, increases availability by about 12%, and increases resource utilization by up to 10%. Manuscript profile

The aim of manipulative procedures in the monotocous species must always be to ensure that the fetus is in normal disposition before attempting delivery. Correction of defects of presentation, position, and posture can be achieved only by intrauterine manipulation of the fetus. Retropulsion of the fetus into the uterus is essential for repositioning it. After diagnosing the cause of dystocia and deciding on a plan of action, the obstetrician should consider whether the available facilities are appropriate, and whether the equipment is adequate to carry out the treatment successfully. In severe forms of dystocia, the veterinarian should always seek the assistance of a professional colleague and consider whether it might be appropriate to transport the animal to a place with hospital facilities, provided that the animal is in a fit state to travel. Obstetrical manipulation per vaginam should be performed as cleanly as possible. It is impossible to perform them aseptically because there will inevitably be some contamination. Manuscript profile

Theory of harmony in existence is a theory of moral value based on a realistic view of morality. This theory holds that all moral values return to a fundamental value; That fundamental value is harmony in existence, and harmony in existence with God plays a central role in moral value in this theory. One question about this theory concerns the place of this theory in the ethics. Is this theory a metaethical theory, or does it belong to normative ethics, or is a third state presumable? By the studies that were done in this research, it was concluded that the basic aim of the theory of harmony in existence is a theoretical aim in the field of normative ethics and also some normative practical aims can be achieved through it. However, the arguments and claims made in this theory are not limited to normative ethics; Rather, they sometimes take on a metaethical aspect, and may go beyond that to include other areas of philosophy. Therefore, it is better to consider this theory as a value theory in accordance with a common term that covers all these areas. Manuscript profile

Most of the previous pricing models for cloud resources which are defined based on auction suffer from high implementation complexity in real cloud environments. Therefore, the main challenge for researchers is to design dynamic pricing models that can achieve three goals: 1) low computation complexity, 2) high accuracy, and 3) high implementation simplicity in real cloud environments. CMM (Cloud Market Maker) is one of the most popular dynamic pricing models that has two advantages of computation accuracy and the possibility to implement in the real cloud environments. This model calculates the bid price based on a linear function. In designing this linear function, the parameters: buyer’s urgency, number of competitors and number of opponents are considered. Despite the advantages of this pricing function, the importance ratio of the constructor parameters of it is considered the same in various market conditions. Ignoring this issue reduces both system flexibility and computation accuracy in tangible changes in the cloud market. Therefore, the authors of this paper focus on designing a new cloud market-aware intelligent pricing system (which developed in customer side of the market) to tackle the mentioned problem. At the same time, high implementation simplicity of the proposed system should be guaranteed. For this purpose, an agent-based intelligent pricing system by combining support vector machine (SVM) and hierarchical analysis process (AHP) techniques is proposed. Simulation results show the better performance of the proposed solution which is named as DPMA in comparison to CMM. Manuscript profile

The study area is located in the south of Qushadagh mountain range, in the north of Asbkhan village, Heris township and in East Azarbaijan province. In terms of structural geology of Iran, this area is located in the main zone of Central Iran and Alborz-Azerbaijan sub-zone. The geological units of the region are including Eocene igneous and pyroclastic rocks with combination of andesitic, Trachyandesitic, basaltic, tuffic and ignembritic. The semi-deep intrusive mass with Oligocene age, with the combination of quartz diorite, diorite and quartz monzonite in the form of stock and dyke is exposed in the area. Structural studies, including fault plates, slickenside on them, and the joints system in various lithologies, indicate at least two general stress directions in the range, Which can be created following one tectonic regime or two tectonic regimes. If we consider the tectonic regime as a phase and consider the tensors with different directions as the result of rotation in the fault plates, We can introduce a general strike-slip regime with a general north-south trend that controls the existing structures of the region. At the same time, the infiltration of intrusive masses has caused the disintegration of these structures and made the issue more complicated. In general, faults with a northwest-southeast trend and a right on strike-slip mechanism, form the main structures of the area.Other faults are controlled by the main structures following the Riddle fractures system. Based on the system of joints in four different lithologies, lithological units from old to new include: basaltic andesite, quartz diorite, quartz monzonite (porphyry mass) and diorite, which from old to new reduces the diversity of the joints system. The northwest-southeast tectonic system has been involved in the development of argillic alteration and the northeast-southwest system has been important in the development of siliceous and mineralized veins.

Application of cloud computing in different datacenters around the world has led to generation of more co2 gas. In addition, energy and throughput are the two most important issues in this field. This paper has presented an energy and throughput-aware algorithm for scheduling of compressed-instance workflows in things-internet by cluster processing in cloud. A method is presented for scheduling cloud workflows with aim of optimizing energy, throughput, and latency. In the proposed method, time and energy consumption has been improved in comparison to previous methods by creating distance parameters, clustering inputs, and considering real execution time. In WSTMOS method by considering special parameters and real execution time, we managed to reach the optimized objective function. Moreover, in the proposed method parameter of time distance of tasks to virtual machines for reduction of number of migration in virtual machines was applied. In WSTMOS method by organizing the workflow inputs to low, medium and heavy groups and also by distributing appropriate load on more suitable servers for processors threshold, we accomplished to optimize energy and cost. Energy consumption was reduced by 4.8 percent while the cost was cut down by 4.4 percent using this method in comparison to studied method. Finally, average delay time, power and workload are optimized in comparison to previous methods. Manuscript profile

In this paper, a model based on meta-heuristic algorithms for optimal allocation of IoT resources based on fog calculations is proposed. In the proposed model, the user request is first given to the system as a workflow; For each request, the resource requirements (processing power, storage memory, and bandwidth) are first extracted. This component determines the requested traffic status of the application in terms of real-time. If the application is not real-time and is somewhat resistant to latency, the request will be referred to the cloud environment, but if the application needs to respond promptly and is sensitive to latency, it will be dealt with as a fog calculation. It will be written to one of the Cloudletes. In this step, in order to select the best solution in allocating resources to serve the users of the IoT environment, the ant milk optimization algorithm was used. The proposed method is simulated in MATLAB software environment and to evaluate its performance, five indicators of fog cells energy consumption, response time, fog cell imbalance, latency and bandwidth have been used. The results show that the proposed method reduces the energy consumption, latency rate in fog cells, bandwidth consumption rate, load balance rate and response time compared to the base design (ROUTER) 22, 18, 12, 22 and 47, respectively. Percentage has improved. Manuscript profile

Mobile edge computing improves the experience of end users to achieve appropriate services and service quality. In this paper, the problem of improving resource allocation, when offloading tasks, based on mobile devices to edge servers in computing systems is investigated. Some tasks are uploaded and processed locally and some to edge servers. The main issue is that the offloaded tasks for virtual machines in computing networks are properly scheduled to minimize computing time, service cost, computing network waste, and the maximum connection of a task with the network. In this paper, a multi-objective hybrid algorithm of particle swarm and gray wolf was introduced to manage resource allocation and task scheduling to achieve an optimal result in edge computing networks. Local search in the particle swarm algorithm has good results in the problem, but it will cause the loss of global optima, so in this problem, in order to improve the model, the gray wolf algorithm was used as the main basis of the proposed algorithm, in the wolf algorithm Gray, due to the graphical approach to the problem, the set of global searches will reach the optimal solution, so by combining these functions, we tried to improve the operational conditions of the two algorithms for the desired goals of the problem. In order to create a network in this research, the network creation parameters in the basic article were used and the LCG data set was used in the simulation. The simulation environment in this research is the sim cloud environment. The comparison results show the improvement of waiting time and cost in the proposed approach. The results show that, on average, the proposed model has performed better by reducing the work time by 10% and increasing the use of resources by 16%. Manuscript profile
