  Abstract Ad hoc Wireless Networks, are networks formed by a collection of nodes through radio. In wireless networking environment, formidable challenges are presented. One important challenge is connection maintenance mechanism for power consumption. In this paper, a multi-objective optimal design is considered for ad-hoc networks which address the electrical power of nodes effects on cross-layer congestion control, routing and scheduling. We first formulate the rate and scheduling constraints. In this way, the multi-commodity flow variables are used. Then, resource allocation in networks with fixed wireless channel and single-rate devices is formulated. Since the electrical power of nodes effects are included in the design problem, we formulate resource allocation as utility and cost function, together in a maximization problem with those constraints. By dual decomposition, the resource allocation problem vertically decomposes into three sub-problems: congestion control, routing and scheduling. These three sub-problems interact through congestion and link price. Simulation results are included to verify the effectiveness of the proposed approach. Manuscript profile

  Software defined networks (SDNs) are flexible for use in determining network traffic routing because they separate data plane and control plane. One of the major challenges facing SDNs is choosing the right locations to place and distribute controllers; in such a way that the delay between controllers and switches in wide area networks can be reduced. In this regard, most of the proposed methods have focused on reducing latency. But latency is just one factor in network efficiency and overall cost reduction between controllers and related switches. This article examines more factors to reduce the cost between controllers and switches, such as communication link traffic. In this regard, a cluster-based algorithm is provided for network segmentation. Using this algorithm, it can be ensured that each part of the network can reduce the maximum cost (including delays and traffic on links) between the controller and its related switches. In this paper, using Topology Zoo, extensive simulations have been performed under real network topologies. The results of the simulations show that when the probability of congestion in the network increases, the proposed algorithm has been able to control the congestion in the network by identifying the bottleneck links in the communication paths of each node with other nodes. Therefore, considering the two criteria of delay and the degree of busyness of the links, the process of placing and distributing the controllers in the clustering operation has been done with higher accuracy. By doing so, the maximum end-to-end cost between each controller and its related switches, in the topologies Chinanet of China, Uunet of the United States, DFN of Germany, and Rediris of Spain, is decreased 41.2694%, 29.2853%, 21.3805% and 46.2829% respectively.

  Transferring the water vapor in the atmosphere directly depend on the conditions of atmospheric circulation, amount and path of humidity changes related to the atmospheric circulation variation. one of the main factors of atmospheric circulation affecting on transferring the moisture is high pressure centers that if placed on the water surface and humidity resources causes the moisture advection in a widely area. However, the role of low pressure systems and cyclones in advection and moisture flux, although not as much as high-pressure systems, but also played a significant role in transmitting and condition of moisture advection. the aim of this study is survey the moisture advection of Iran's precipitations. in this regard, pressure data, specific humidity, u wind and v wind parameters in 500, 700, 850 and 1000 hpa from NCEP/NCAR database were extracted and analyzed. the results showed that the moisture advection of iran's precipitations is related to the moisture advection pattern of low pressure of dual-core of Sudan and east Mediterranean - Europe high pressure, moisture advection pattern of multicore low pressure of central Iran, east Mediterranean and south east of Saudi Arabian, moisture advection pattern of high-pressure of north west of Europe- low pressure of Persian gulf, moisture advection pattern of high pressure of Siberia and Kazakhstan- low pressure of south east of Iran and low pressure of Mediterranean. Overly, the results showed that Arabian Sea in low level and Mediterranean Sea in high level had an important role in moisture advection of Iran's precipitations. Manuscript profile

  The Nasrand granitoid intrusion, which is located at southeast of Ardestan, consists of granite and granodiorite that intruded Eocene volcanic rocks and cut by NW-trending doleritic dikes. The granitic rocks display granular, pertitic, granophyric and poikilitic textures. Plagioclase crystals in these rocks composed of two distinct generation (large phenocrysts along with inclusions of lath-shaped crystals) and often exhibit zoning patterns and sieve textures. The conspicuous disequilibrium textures in the granitoid rocks may suggest that magma mixing beside fractional crystallization play a significant role in the formation of the plutonic rocks. In confirmation of petrographic data, crystal size distribution (CSD) technique was also used to determine crystallization conditions and magmatic processes that lead to the formation of the rocks. Increasing of feldspar crystal size in a semi-logarithmic plot of population density versus size represents fractional crystallization, whereas disruption and curvature of cumulative density of plagioclase and orthoclase on the semi-logarithmic diagram, indicating the arrival of new magma into the magma reservoir and confirm the importance of magma mixing. Additional chemical features such as variation trends of Rb versus Rb/Sr and Nb versus Nb/Y in the samples can be regarded as an indicator of magma mixing processes. Manuscript profile

  Ramand region is a part of Urmia-Dokhtar magmatic belt that is located among a variety of crossed faulted structures and magmatic occurrences including Paleogene rhyolite and rhyodacite formations as the major related host units to hydrothermal ore deposits. Different kinds of clayey, silicified and Fe-rich alterations indicate a post magmatic vein type mineralization potential along Ramand crushed zones and structures. Well-developed alterations have been extended around volcanic extrusions with variety of textural zonation in quartz and chalcedonic vein systems similar to epithermal deposits. This research introduces a fractal based technique (Area-Concentration function) to obtain the priority map of Au-mineralization with an emphasis on quartzitic-pyritic textural evolutions in Ramand region. As a rule, self-organized crystallized textures (such as crustiform quartz) have more valuable ore content than glassy textures (vitrophiric), because of stepwise enrichment advantages in the hypogenic environment of epithermal deposits. Litho-geochemical sampling is the main and prior procedure for studying quartz textural zonation as well as instrumental quantitative measurement of the elements. Results showed a volcanic hosted formation with crustiform quartzitic textures is mineralized in the western part of Ramand region. Mineralized veins are specified by silica nonlinear distribution (SiO2) related to textural evolutions in the quartz-hematite facies (Au=820 ppb) as the main targets for detail explorations.

  Irrigation networks are responsible for the distribution and delivery of agricultural water, so improving their performance reduces losses and increases the efficiency of water distribution, and thus leads to improved water efficiency. Investigating the operation of irrigation networks is essential for planning and improving irrigation networks and systems. The first purpose of the assessment is to determine the amount of losses that occur in the process of distribution and delivery of agricultural water in the network of irrigation canals. Losses in agricultural water conveyance and distribution systems occur for two main reasons: leakage and improper performance of canal structures that cause operating losses. Various factors such as weed growth in canals, accumulation of sediment in canals, accumulation of garbage in canals, cracking of canal cover, crushing or moving of concrete parts in canals, destruction due to poor quality of materials and lack of sufficient knowledge of total operation and the wisdom of the country's water decision-makers is increasing losses in agricultural distribution and delivery systems. Factors influencing the operation of networks include regular annual maintenance process and the operation of network operators to timely and correctly adjust the catchment structures to prevent unstable hydraulic conditions in the main and secondary channels, which can be invested in training operators and teams. Management and operation in irrigation networks significantly reduced the volume of operation losses. In this study, the results of studies on the determination of conveyance and distribution efficiencies in irrigation networks have been reviewed and summarized. Manuscript profile

  The government's responsibilities towards involuntary civil responsibilities are important and fundamental issues that have not been addressed much. At the same time, the government's duties in this regard, given the growing importance of citizens' rights, are important and necessary issues for discussion. The main question that has been raised and examined in this article in the present article is what is the responsibility of the government from events from its moral and legal point of view? What are the jurisprudential principles, moral and legal principles, conditions and duties of the government towards responsibilities beyond its control? The present article is descriptive-analytical and examines the mentioned questions using the library method. The results of the article indicate that in Iranian law, the government is committed to responsibilities beyond its control. The theory of equality of citizens, the theory of distributive justice, the theory of guarantee of rights, the observance of the rule of justice and the theory of the insuring state are the moral and legal foundations of the government's responsibility for unintentional events. Lack of reason or his inability to pay the ransom, the judge's mistake in judging the government's duty in the event of an accident, and the government's obligation to pay the ransom for traffic accidents (bodily injury insurance fund). One of the most important examples is the responsibility of the government towards responsibilities beyond its control. Manuscript profile

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

  By the introduction of the concept of Next Generation Networks (NGN), the management of these networks has become an important issue. So, the requirements, goals and the overall architecture of NGN management systems are discussed in this paper. The functional classification of Operation Support Systems (OSS) used in NGN management is also presented. Because of the need of utility networks (such as telephony, data, water, electricity and gas) in the country to OSS, the amount of required capital investment for deployment of Network Management System (NMS) and Customer Care and Billing System (CCBS), as main parts of OSS, are calculated for the next four years in this paper. To reach these estimates, the total number of subscribers in mentioned networks is forecasted for this period and information about per customer capita is also extracted. Two frameworks of, distributed and centralized, are considered. This assessment shows an approximate investment of M606$ and M432$ is needed for NMS and CCBS in distributed scenario, respectively. The same requirement in centralized scenario is M433$ and M322$ for NMS and CCBS, respectively. So, an approximate investment of M1040$ and M750$ is needed for OSS in distributed and centralized scenarios, respectively. Manuscript profile

  Faults in MV systems are the cause of almost 70 percent of outages in power system. By using suitable outage management methods, amount of power outages will be reduced in large extent. In Iran, traditionally outage management system was conducted by trial and error methods and relied on operators’ experience. The ever-increasing expansion of distribution networks has made it impossible to use traditional outage management systems. Outage management systems depend upon load type, load sensitivity, network type, amount of accumulation of load and population, and being rural or urban network. In this paper, at first a technical assessment for implementing outage management methods in distribution systems of Iran is carried out. An economic assessment of implementing outage management system in urban distribution systems of Iran with dense population is conducted. For this purpose a sample network of Afsarieh area of Tehran has been chosen. Manuscript profile

  Semantic web has been one of the most important research areas of computer science in recent years. The concept of ontology as one of the most elements of semantic web is used to formally describe the domain knowledge and to enable the reasoning capability. Semantic web is a distributed system and ontologies may be developed on many different nodes, so centralized reasoning is very hard or even impossible in many cases. On the other hand, since the majority of information in semantic web is uncertain, considering the notion of uncertainty in ontological reasoning is crucial. In this paper a method for distributed reasoning in uncertain ontologies is proposed. For this purpose the distributed description logic (DDL) framework and the certainty theory are considered for distributed reasoning and modeling the uncertainty respectively. To evaluate the functionality and performance of the algorithm, we developed a case study on application of the proposed method in purifying the mappings between ontologies. The results show that our algorithm makes the mappings more precise than other similar methods. Manuscript profile

  In this paper, a new structure composed of a negative capacitance and resistance is presented in order to increase gain and bandwidth of distributed amplifiers. The proposed structure is used at the gate transmission line of the distributed amplifier and the obtained circuit has been simulated using 0.13µm CMOS model. The negative capacitance at the gate transmission line decreases parasitic effects of gain cells and increases amplifier bandwidth and accordingly increases voltage gain. The generated negative resistance decreases transmission lines losses and increases bandwidth. Simulated voltage gain is 15dB with ±0.5 dB gain flatness over 0.5-49 GHz frequency band. Circuit input and output are matched with 50Ω resistance; and input and output return losses are -8.15 dB and -9.2 dB, respectively. This circuit has a noise figure less than 4.6 and its power consumption is 99 mW from 1.8 V power supply. Manuscript profile

  A group of small generators and energy storages in the low or medium voltage distribution systems beside of consumers emerge to a new power system called micro grid. Micro grids are designed to have secure and economic operation isolated and connected to the network and exchange electrical energy with distribution system. Hence, they may impact on planning and scheduling of distribution systems. In this case, network reconfiguration is a considerable issue after presenting of micro grids to the system. In the previous studies regarding to this issue, micro grid is considered as a distributed generation which should only produce electricity to the network. In this paper, micro grid is modeled as a power exchanger in the distribution network to study the effect of it on the network reconfiguration. For this purpose, reconfiguration is formulated as a multi objective optimization problem using max-min fuzzy method. In this problem, power loss reduction and load balancing among feeders are two independent objectives and voltage profile, lines congestion, radial network structure and load flow are equality and inequality constraints. Particle swarm algorithm is applied to solve the optimization problem and the reconfiguration over two 33 and 70 buses IEEE test network is shown. Results demonstrate that replacing traditional distribution systems by modern active networks and exchanging power with micro grids can lead to increase the reliability of system and more economic operation.

  The basic approach of this paper is to improve the operational condition of distribution systems by the simultaneous utilization of system reconfiguration and direct load control programs. A Genetic Algorithm (GA) based algorithm is employed to find the optimal states of switches as well as the optimal incentives of the demand response programs. The concept of price elasticity of demand is utilized to illustrate the changes of electricity consumption pattern as a result of customers’ participation in Demand Response (DR). The objective function of the proposed model is network operation costs. In addition, voltage constraints, lines capacity limits and the related constraints of DR programs are considered in the optimization problem. Finally, the effectiveness of the proposed method in reducing operation costs is shown using the 33-bus distribution network. The simulation results show that the coordination of reconfiguration and DR can reduce the operation costs and load shedding requirements in addition to solving lines’ over loading problems.

  After the restructuring and privatization of the electricity industry, the main purpose of the DISCOs is to increase their income, according to the existing laws. The existence of private distributed generation (DG) units in the distribution network and the possibility to buy additional electricity of DG with a less price than the wholesale market, capacitor installation, payment of energy not supplied to customers, the cost of energy losses and voltage drop problem in the distribution network, has created opportunities and challenges for DISCOs that are looking for adopting a suitable strategy for higher profits. In this paper, as the first scenario, it is depicted that when there is no DG unit in the network the increasing in the DISCO’s income is achievable by optimal allocation of both fixed and switched capacitors. In the second scenario, this is done by determination of the maximum acceptable DG energy sourced electricity purchasing price with a known location, and in the third one, by determination of the purchase price from the DG while the locating has been done by the DISCO. Simulation studies are done on a 20kV 18-bus distribution network in Rasht city, and the results are presented at the end. Manuscript profile

  : In this paper, optimal locating for AVRs and reconfiguration of distribution networks were assessed simultaneously as an optimization problem. A new objective function was introducing which incorporated several electrical indices including real power losses, reactive power losses, reliability, voltage profile, voltage stability, and load capacity of lines (MVA). Various load levels were incorporated into the objective function to make sure that switch status in reconfiguration and AVR taps and locations would be robust against load variations. This paper also introduced a new method for calculating the load levels with respect to load uncertainty. It also considered all loads based on a voltage-dependent model. Several scenarios are defined to thoroughly assess the proposed approach. Integer particle swarm optimization algorithm (IPSO) was used to solve the mentioned optimization problem. The results obtained by the simulation of 33-bus and 69-bus standard IEEE .radial power distribution networks demonstrated the effectiveness of the proposed approach Manuscript profile

  Energy efficiency is one of the most important issues in the power system studies and many methods are used to improve power systems efficiency. Combined cool, heat and power (CCHP) systems are one of the most important technologies that can improve power system efficiency and these systems use their excess heat for supplying heat and cool loads. This paper presents a framework for optimal operation of CCHP systems in a microgrid. At first the unit cost functions are used to optimize operation of CCHP units. Then the algorithm determines the optimal operating strategy of microgrid units. A multi-criteria operation optimization method is proposed that uses primary energy consumption, pollution emissions and operating costs as criteria. The case study is performed for a nine bus microgrid and the results are compared with reference articles results and the advantage of the proposed method is investigated. Manuscript profile

  In this paper, in order to reduce torque ripple for low speed range in non-commutation region, instead of exciting by a DC current, a adjustable current according to rotor position is injected. Also, to reduce torque ripple in commutation region the modified torque sharing function (TSF) method has been used. In the proposed method, TSF is modified by a feedback from the motor speed and applying it to a fuzzy controller according to speed value. In the proposed method, motor speed, torque error, and torque error derivative are used as fuzzy controller inputs, which Turn-On and overlap angles between the phases are changed as a function of motor speed. Also reference torque of adjacent phase is modified as a function of torque error and torque error derivative. In this method, TSF is modified dynamically and momentary. The exact simulation based on Matlab/Simulink for a 3-phase 6/4 SRM are carried out to verify the effectiveness of the proposed novel method for 0 to 1500rpm speed range. Manuscript profile

  One of the most important applications of wireless sensor networks was to estimate the unknown phenomenon. The cooperative activities of wireless sensors and scattered information of sensor nodes over network are used to decentralized estimation. Precoder design done on the sensor nodes in order to provide an optimal estimate of the actual amount. Precoder design is an optimization problem. Since the channel is wireless link on the wireless sensor networks. Therefore, assuming the access of full channel state information isn't correct in this network. Since the perfect channel state information is required in the precoder design process, so the effects of the channel estimation investigated on precoder design process. On the issue of channel estimation, channel estimated by using of the known training sequence method with LS and MMSE criteria. Since power restriction is the key subject in the wireless sensor networks, therefore in this study power restriction considered in the channel estimation and precoder design problem.

  This paper presents the problem of distributed estimation in an incremental network based on the family of normalized subband adaptive algorithms (NSAAs). The distributed NSAA (dNSAA), the distributed selective partial update NSAA (dSPU-NSAA), the distributed dynamic selection NSAA (dDS-NSAA), and the dSPU-DS-NSAA are introduced in a unified way. The dNSAAs have better convergence speed than distributed normalized least mean square (dNLMS) algorithm especially for colored Gaussian input of the nodes. In comparison with dNSAA, the dSPU-NSAA, and dDS-NSAA have lower computational complexity and close performance to dNSAA. Also by combination of these algorithms, the dSPU-DS-NSAA is established which is computationally efficient. In addition, a unified approach for mean-square performance analysis of each individual node is presented. This approach can be used to establish a performance analysis of classical distributed adaptive algorithms as well. The theoretical expressions for transient, and steady-state performance analysis of the various dNSAAs are introduced. The validity of the theoretical results, and the good performance of these algorithms are demonstrated by several computer simulations. Manuscript profile

  Due to the high-speed of information generation and the need for data-knowledge conversion, there is an increasing need for data mining algorithms. Clustering is one of the data mining techniques, and its development leads to further understanding of the surrounding environments. In this paper, a dynamic and scalable solution for clustering mixed big data with a lack of data is presented. In this solution, the integration of common distance metrics with the concept of the closest neighborhood, as well as a kind of geometric coding are used. There is also a way to recover missing data in the dataset. By utilizing parallelization and distribution techniques, multiple nodes can be scalable and accelerated. The evaluation of this solution is based on speed, precision, and memory usage criteria compared to other ones. Manuscript profile

  To communicate with people interactive systems often need to understand human activities in advance. However, recognizing activities in advance is a very challenging task, because people perform their activities in different ways, also, some activities are simple while others are complex and comprised of several smaller atomic sub-activities. In this paper, we use skeletons captured from low-cost depth RGB-D sensors as high-level descriptions of the human body. We propose a method capable of recognizing simple and complex human activities by formulating it as a structured prediction task using probabilistic graphical models (PGM). We test our method on three popular datasets: CAD-60, UT-Kinect, and Florence 3D. These datasets cover both simple and complex activities. Also, our method is sensitive to clustering methods that are used to determine the middle states, we evaluate test different clustering, methods. Manuscript profile

  This research is in the field of machine translation and in relation to extraction of Persian-English chunks from bilingual corpus by Spark. In this regard, the most important challenge is that the operation must be carried out on large corpus; therefore, it requires distributed computing along with big data analysis techniques and tools. When translating text, we are usually confronted with chunks that we need to find the corresponding chunks of each one in the target language and insert it in our translation; this is accomplished by locating it in a corpus that contain the chunks and their corresponding translations. The existing methods, perform this operations in a non-distributed way, therefore while they run slowly, they cannot use a very large corpus. To overcome this shortcoming, in this research a distributed method has been presented, which also takes distance between the sections of chunks into account. The proposed method extracts all possible chunks from the input sentences in the monolingual corpus and uses the correlation coefficient to translate those chunks using the bilingual corpus. We implemented the proposed algorithm in a platform consisting of a computing cluster with sixty-four GB of memory and a twenty-four-core processor in Spark. The incorporated experimental data was a Persian and an English monolingual corpus along with an English-Persian bilingual corpus, each of which containing 100,000 sentences. Experimental results show that run time could greatly be reduced, and the quality of translation is also significantly improved. Manuscript profile

  One of the main components of distribution systems is transformer, and their failure will cause irreparable damage in power systems and distribution companies. These failures are to increase the losses of the transformers due to the increase of harmonics, especially the current harmonics. These losses increase the temperature of transformers and reduced the lifetime of distribution transformers. In this paper evaluated losses and lifetime in the presence of harmonic loads in Ilam distribution transformers. Technical and practical assessments of the presence of harmonic loads and their effect on the lifetime of transformers have been investigated. According to the obtained results the useful lifetime of some transformers from 30 years to 17 years are decreased. Manuscript profile

  In electric vehicle’s nonlinear dynamic equations, some parameters has uncertainty such as the coefficient of rolling resistance, drag coefficient, armature resistance and field winding resistance. Design of a controller that is robust in the presence of these parametric uncertainties and also in presence of external disturbances, and on the other hand simultaneously satisfies the optimality criteria, is a challenging issue. In practical applications, in addition to the above problem, the computational load of the control input should also be considered and provide a rational interaction between the controller's desirable performance and the calculations volume. In the present paper, a robust optimal stable fuzzy controller based on the parallel distributed compensation is designed, using Takagi-Sugeno fuzzy model of electric vehicle. The stabilizer feedback gains of fuzzy model, the upper bound of the uncertainties, the upper bound of the disturbances effect, and the upper bound of the cost function are obtained completely offline, through the solving of a minimization problem based on the linear matrix inequality. Therefore, the calculation volume of the control input is extremely low. This allows the practical implementation of the proposed controller. The favorable performance of the proposed controller is demonstrated in five-step simulations. Manuscript profile

  The steady state error in voltage amplitude and frequency and improper reactive power sharing are main disadvantages of droop control in primary level of control of distributed resources (DERs) in microgrid. Secondary control can compensate these problems. In contrary to centralize control, distributed secondary control may bring merits such as reliability, flexibility and scalability improvement. The distributed secondary control is usually implemented using consensus algorithm whose communication network is very important. Communication network is usually modeled continuously with a constant transfer rate. In this paper, the consensus algorithm with communication network are implemented in discrete domain because of discrete nature of them. Two aperiodic data transfer strategies state dependent and state independent are also proposed for releasing communication network burden where data rate is not fixed. Time delay as a non-desirable effect is evaluated. The proposed method applied on an islanded microgrid, and simulation results show the effectiveness of the proposed method. Manuscript profile

  The purpose of distribution networks restoration is to re-energize the out-of-service loads after fault occurrence which is accomplished by changing the status of network switches and considering the network constraints. In this paper a multi-stage restoration method by the help of the modified decision-making tree algorithm is proposed to maximize the restored loads and also to minimize switching operations. The main stages of this method include initial restoration, reconfiguration and optimal load shedding. To reduce the search space, the network switches are categorized into different sets which avoid having any inappropriate result space. The proposed method is tested on two IEEE 69-bus and 119-bus distribution networks. The simulation results confirm the accuracy and efficiency of the proposed method in distribution network restoration. Manuscript profile

Recent research efforts are investigating on how to better exploit fog capabilities for execution and supporting IoT applications. Also, the distribution of an application’s components on the possible minimum number of fog nodes for the sake of reduction in power consumption leads degradation of the service reliability level. In this paper, a hybrid meta-heuristic algorithm based on cuckoo search algorithm is presented for static deployment the components of IoT applications on fog infrastructure in the aim of trade-off between efficient power usage, reduction in the effect of one point of failure and boosting the application reliability against failure.

  A sophisticated and accurate probabilistic computational procedure for the calculation of lightning failures and evaluation of MCA performance for reduction of failures is implemented in this paper. Calculation of induced overvoltage caused by indirect lightning is implemented based on the Agarwal method with consideration of lossy ground. The Monte Carlo method with backward scenario reduction is implemented to take into account the uncertainty of lightning flash parameters including peak current and front time with the distance of the striking point from the distribution line with applying a proper model for simulation of MCA in ATP-EMTP software. A link is developed between MATLAB and ATP-EMTP software to simulate the numerous generated scenarios and analyze the output results. Different conditions including the insulation strength of the line, the earth conductivity, and the shielding factor of the adjacent objects to the line are also taken into account in calculations. The results are presented in a proper way to make them useful for the determination of lightning-related failure rates and also accurate evaluation of the effectiveness of MCA installation in different conditions of distribution feeders.

  The growing penetration of electric vehicles (EVs) in distribution networks (DNs) has posed many challenges for electricity distribution companies, such as: increasing the amount of voltage drop, network losses and the number of outages due to the overload. To overcome this, it is recommended to use coordinated charging methods. However, these methods require telecommunication, measurement and processing infrastructure with high costs and can only be implemented in smart grids. In this paper, a semi-intelligent method for charging EVs is presented that does not require complex infrastructure. This method, using a simple and inexpensive local automation system, charges EVs in the off-peak periods of the DN and thus improves its parameters. Since the EVs are charged at the low tariff time intervals, the proposed method will also benefit the EV owners. To achieve real results, four-wire DN is considered to model the effect of neutral conductor. To confirm the effectiveness of the proposed method, it is compared with different uncontrolled charging methods. A standard 19 bus test system is used for simulations. Manuscript profile

  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

  Multilateral export control regimes are among major tools used by developed Western countries during the past six decades to maintain their technological supremacy under the pretext of preventing proliferation of weapons of mass destruction. These regimes have grown and developed unprecedentedly in both quantitative and qualitative terms especially in the past decade following 9/11 terrorist attacks. Opponents and proponents have offered various viewpoints on the legality or illegality of these regimes on the basis of the international law. This research first presents a theoretical framework for the assessment of those viewpoints. Since both opponents and proponents have emphasized on the relationship between these regimes and international nonproliferation regimes, their implications for availability of equipment and material related to weapons of mass destruction, conventional weapons, missiles, and dual-use goods and material are briefly discussed. Finally, developments of these regimes in addition to viewpoints of proponents and opponents about legality and illegality of export control regimes are explained using a comparative study of commitments of states members of these regimes and their commitments under international nonproliferation treaties. The conclusion is that such export control regimes, which have been developed by their members to create monopoly on technical know-how and technology, are incompatible with commitments of member states under international law Manuscript profile

  During the past two decades, many states and groups of states have offered proposals for structural reforms in the UN Security Council. Some proposals seek to increase the number of permanent members of the Council. The G4 –Germany, Japan, India and Brazil – seems to stand a better chance in this regard. This paper discusses special opportunities for permanent membership of this group in the Security Council while considering challenges facing it. All four countries enjoy comparative advantages in their own geographical regions which give them the chance to seek a permanent seat in the Security Council. On the other hand, they face two kinds of obstacles: regional and international obstacles. For some of these states, overcoming regional obstacles is more difficult than international ones and the opposite is true for others. This research aims to answer this question: What are the opportunities and challenges facing member states of this group in their effort to gain permanent seats in the Security Council?

  Internet of Things (IoT) is a network of objects on which objects can communicate with other objects. The Internet of Things is currently constantly under numerous attacks due to technical, legal and human problems. One of the most important of these attacks is the Denial of Service (DoS) attack, in which normal network services are out of service and it is impossible for objects and users to access the server and other resources. Existing security solutions have not been able to effectively prevent interruption attacks in Internet of Things services. Software-oriented network (SDN) is a new architecture in the network based on the separation of the control and data plane of the network. Programmability and network management capability by SDN can be used in IoT services because some IoT devices send data periodically and in certain time intervals. SDN can help reduce or prevent the data flood caused by IoT if properly deployed in the data center. In this article, a method to detect DDoS attacks in Internet of Things based on SDN is presented and then an algorithm to reduce DDoS attacks is presented. The proposed method is based on the entropy criterion, which is one of the most important concepts in information theory and is calculated based on the characteristics of the flow. In this method, by using two new components on the controller to receive incoming packets and considering the time window and calculating entropy and flow rate, a possible attack is detected in the network, and then based on the statistics of the flow received from the switches, the certainty of the attack is determined. Compared to the existing methods, the proposed method has improved 12% in terms of attack detection time and 26% in terms of false positives/negatives. Manuscript profile

  Today, in many control methods, neighboring system information is used for better control and synchronization between different units, and therefore, in the access and transmission of information through communication links, problems such as disruption, uncertainty, noise, delay, and cyber-attacks occur. In this paper, the effect of the Denial of Service (DoS) cyber-attack on the microgrid in island mode is investigated and a cooperative distributed hierarchical controller is designed with the presence of this cyber-attack. Distributed Generations (DGs) have been analyzed with the help of multi-agent systems and the communication network between them using graph theory. The effects of the DoS cyber-attack on the model of DGs are mathematically formulated and in proving the stability and synchronization of frequency and voltage, the suitable Lyapunov function is presented and the stability analysis of DGs against these cyber-attacks is performed and the stability and synchronization conditions of DGs are proved. To confirm the proposed theoretical issues, a case study model is simulated despite the DoS attack on the communicative links in Matlab Simulink, and the results show the performance of the designed controller in different conditions.

  Bovine hoof with its fine structures and accurate function is used for routine locomotion. This part of common integument has special characteristics to carry on a very high resistance to external/internal stimuli. Production and components of different parts of this small region vary and its variation in origin of production makes different protection against systemic disturbances or external/internal forces. Variation among species like cattle and horse limbs, expected performance (confinement and milk production versus athletic performance) and metabolic pressure on each animal results in different outcomes after hoof pathologies. For example, unlike horse, in cattle sinking of 3rd phalanx is more pronounced in the heel region. Horn capsule with its firm, sensitive and complex structure tries to neutralize the forces to which the limb is subjected. Any abnormality in hoof capsule vital tissues is a beginning for claw horn disruption lesion (CHDL) in a dairy farm. There are many hypotheses aiming to describe CHDL pathogenesis. No longer is it acceptable to believe that SARA = Subclinical laminitis. The disorder cannot be managed simply from a nutritional perspective and is Multifactorial. With better understanding of each part of this complex structure and the processes that occur after damage, a better understanding of the physiopathology of hoof capsule injuries is obtained.

  The end of Second World War has marked the beginning of an era of renovation and development for many countries in the world and European and Asian countries have utilized several development strategies based on their situation. South Korea is one of those countries. Having an ancient history, South Korea is one of the most integrated and stable countries in the world. Its development which starts right after the end of the second world war and Japanese colonization is an outstanding example of fast and extraordinary development in a short time span. Despite having the bitter experience of being colonized, what happened as a consequence of the second world war, the division of the peninsula into two parts (North and South) and the civil war following that, and the severe poverty and dependence on international aid, it is one of the Asian Tigers, together with Taiwan, Singapore, and Hong Kong. Having an authoritarian but developmentalist government, a strong sense of nationalism against foreigners, Confucian culture, a focus on export expansion strategies, and the development of an education system based on economic needs and changes are among the influential factors discussed in this paper. Finally, the development model of South Korea is presented. Manuscript profile

  Special conditions of wireless sensor networks, such as energy limitation, make it essential to accelerate the convergence of algorithms in this field, especially in the distributed compressive sensing (DCS) scenarios, which have a complex reconstruction phase. This paper presents a DCS reconstruction algorithm that provides a higher convergence rate. The proposed algorithm is a distributed primal-dual algorithm in a bidirectional incremental cooperation mode where the parameters change with time. The parameters are changed systematically in the convex optimization problems in which the constraint and cooperation functions are strongly convex. The proposed method is supported by simulations, which show the higher performance of the proposed algorithm in terms of convergence rate, even in stricter conditions such as the small number of measurements or the lower degree of sparsity.

  In many microgrid control methods, the output information of sensors and actuators of neighbouring distributed generators (DGs) is used to stabilize and synchronize voltage and frequency. Many problems such as disturbances, uncertainty, unmodeled dynamics, cyber-attacks, noise, time delay, and measurement errors cause invalid data problems and errors in the system. Better microgrid control depends on the quality of data measured or sent from the output of sensors and actuators. In this paper, according to the advantages of the Cooperative distributed hierarchical control, it is used for control and synchronization in the islanded microgrid with the presence of sensor and actuator error. To synchronize DGs with multi-agent systems and communication channels, it is modeled with graph theory. To stabilize and synchronize, sensor and actuator error in the DG model is mathematically formulated. In the proof of stability and synchronization, the appropriate Lyapunov candidate is presented and the conditions of stability and synchronization are proved. Finally, to show the effectiveness of the designed controller in solving communication channel problems and verifying the presented theory, a case study is simulated in the MATLAB/Simulink software environment with the presence of error and cyber-attack of sensors and actuators.

  Today, with the growing demand for hybrid electric vehicles in microgrids, electricity supply, environmental issues, and rescheduling are among the challenges of microgrids that must be solved and suitable solutions provided. To overcome these challenges, this paper introduces a new multi-objective optimization model, which in the first objective, minimizes the total operation cost of the microgrid, and in the second objective, improves the reliability index by reducing the amount of energy not supplied. Due to these two objectives, a multi-objective evolutionary seagull optimization algorithm is used to find the optimal global solutions. In this regard, hybrid electric vehicles and demand response programs are used to smooth out distribution nodal prices and reduce CO2 emissions. The 69-bus distribution network has been used to evaluate the efficiency of the proposed method. Manuscript profile

  The Granitoid plutons in the Sanandaj-Sirjan zone host numerous pegmatitic dikes. This study is focused on mineral chemistry of zircons in the pegmatite dikes in the Malayer, Boroujerd and Shazand district to evaluate zircon crystallization temperature, oxygen fugacity and Ce4+/Ce3+ ratio and also zircon/rock partition coefficients of REEs and U, Th, Ta, Nb and Y. Trace element discrimination digrams such as Th versus Y and Yb/Sm versus Y and Nb, indicated studied zircons were located in the syenite pegmatite field. Zircon/rock partition coefficients indicate that zircon granis are enriched in the HREE than LREE. Zircon chemistry show that zircon in the Shazand and Malayer pegmatite dikes have more Hf and less REE distribution than zircons in the Boroujerd pegmatite dikes. Consequently, it indicates the role of latter hydrothermal process in the formation of Boroujerd zircons. Crystallization temperature, oxygen fugacity and Ce4+/Ce3+ ratios decrease from Malayer to Shazand and finally Boroujerd pegmatite dikes. Reduced condition of magmatism, Th/U contents below 1 and Y/Ho content higher than 20 indicate that these pegmatities are barren. Manuscript profile

  With the advancement of science, in many control methods, the neighbor system is used to better control and synchronize between different information of microgrids. There are problems in accessing and transmitting information through communication links. In this article, vulnerability and acceptance of secondary control methods are distributed. Also, denial-of-service (DoS) cyber-attacks, sensors and actuators, and hijacking on the island microgrid have been investigated. In addition to stability, synchronization is also analyzed in this article. Multi-agent systems have been used for synchronization. Cyber-attacks are mathematically formulated in the controller. A suitable controller is designed to eliminate the attacks. In the stability and synchronization of frequency and voltage, the Lyapunov function is presented and simultaneous analysis of stability and synchronization has been done with practical proofs. The resilience factor has been calculated for different attacks. It is shown that the system is resilient against cyber-attacks. A case study has been simulated in MATLAB/Simulink to approve the theoretical issues. Manuscript profile

  The online rating system on most websites provides users with a rating for products and services. The lack of trust in the correctness and non-manipulation of data has caused users' satisfaction to not be provided as it should be. Considering that the existing online scoring system deals with a central server, all score data is stored in a central server; Therefore, all score data can be deleted, changed and manipulated by the system administrator to change the score results in favor of the service or product provider. In this research, the online scoring system using distributed ledger technologies has been introduced as a proposed system to solve all the weaknesses in the current systems. Distributed ledger technologies are a type of technology that works in a decentralized manner and there is no focus from any entity on this technology. There are different types of distributed ledger technologies. Among distributed ledger technologies, block chain technology is chosen for the proposed scoring system due to its smart contract support. In the proposed online scoring system, the performance criteria of a node are unknown and therefore cannot be used directly to optimize the segmentation results. To solve the performance problem caused by the difference of nodes in the blockchain without knowing the different characteristics of the nodes, we propose a new segmentation method called NoRS. This proposed method consists of four phases: NoRS schematic, scoring mechanism, segmentation strategy, transaction confirmation, creation and release of new block. Therefore, by reviewing the transaction process reports, we evaluate the nodes and assign them to different committees based on the score corresponding to each node; With this process, the ratio of different nodes within the committee is balanced to improve the blockchain transaction efficiency. The advantages of the proposed scoring system compared to the existing systems are that the proposed system works in a decentralized manner and the information cannot be manipulated. Also, the privacy of the scorers is preserved and the transparency of the data is guaranteed. Manuscript profile

  In this paper, the problem of sensor fault estimation and designing of a distributed fault-tolerant controller is investigated to guarantee the leader-follower consensus for homogeneous singular multi-agent systems for the first time. First, a novel augmented model for the system is proposed. It is shown that the proposed model is regular and impulse-free unlike some similar research works. Based on this model, the state and sensor fault of the system are simultaneously estimated by designing a distributed singular observer. The proposed observer also has the ability to estimate time-varying sensor fault. Then, a distributed controller is designed to guarantee the leader-follower consensus using estimation of state and sensor fault. The sufficeient conditions to ensure the stability of the observer dynamic and consensus dynamic are drived in terms of linear matrix inequalities (LMIs). The gains of observer and controller are computed by solving these conditions with MATLAB software. Finally, the validation and efficiency of the proposed control system for the leader-follower consensus of singular multi-agent systems exposed to sensor faults is illustrated by computer simulations. The simulation results show that the propsed control strategy deeling to the sensor falut in the singular multi-agent systems is effective. Manuscript profile

  Distributed generation refers to the generation of electricity near the consumer's location using small-scale generation units. Scattered energy sources are renewable energies and combined production (simultaneous production of electricity and heat). A virtual power plant refers to a set of distributed production facilities such as wind turbines, solar power plants, small hydropower plants and any power generation sources that have the ability to cooperate with each other in a local area and are all controlled by a central control unit. The virtual power plant has been subjected to various validation tests and network connections (connected to the network and off the network) and has a high level of credibility and competence. This research includes an overview of some virtual power plant ideas that express a better understanding and a more general vision in this field, some general control structures are described and experimental fields are introduced. The distribution network is represented by the virtual power plant. The result shows that with the presence of storage resources and the possibility of being in the reservation market, the virtual power plant will benefit more. Manuscript profile

  Given that waters are part of the debate and the discussions are possessed of the capability, the question arises as to whether public waters are owned by individuals. According to the Water Act and how it becomes nationalized in 1347, the waters of the Maqdah became one of the public property administered by the government. According to some jurists, by the adoption of the Water Nationalization Act on 4/4/1347 Articles 149, the Civil Code has been abolished and the issue of water ownership has been abolished. The general property of the national wealth is a country and belongs to all generations. The economic value of this property first provides special support and maintenance of these property. There are many solutions such as using new technologies, strengthening regulatory agencies, and so on to prevent private people's access to public property and to prevent government and public outsourcing over these property. But one of the most important ways in this regard is to provide legal solutions as a way to solve the roots of problems. In this study, jurisprudential and legal views will be examined and solutions will be provided to solve the legal problems of public water. Manuscript profile

  Polymer-bonded explosives are widely used in defense and commercial industries. In this type of explosive, very high amounts of explosive crystals (about 90% by weight) are surrounded by a polymeric binder (about 10%), which leads to a decrease in sensitivity and a significant increase in safety during application and storage. These mixtures are molded in different ways, such as pressing, casting, extrusion, and injection. Studying the rheology of these mixtures with a high percentage of solid loading leads to finding the appropriate quality control method at different production stages. The first step was to review studies on alternatives to simulating explosive rheological behavior, such as dechlorane, calcium carbonate, sugar, etc. The general behavior of simulated mixtures, such as yield stress, shear rate dependence, time dependence, etc., is compared with original explosive. The results showed that despite the similarity in some rheological behaviors, it is impossible to predict and study all the rheological behaviors of polymer-bonded explosives using simulating materials. This paper discusses factors affecting the rheology of polymer-bonded explosives, such as particle size distribution, modification of explosive crystal surfaces, and plasticizer. A review of scientific sources showed that using a wide distribution of explosive crystal particles compared to a narrow distribution led to a significant reduction in viscosity and dependence on shear rate and time. The absence of strong interactions between crystal particles and polymer binder leads to no observation of quasi-solid behavior even in 85% by weight of explosive crystals such as octogen in hydroxyl-terminated polybutadiene Manuscript profile
