Marine currents have different categories that tidal currents are among these currents. Near Japan, there is a current in the ocean known as the Kuroshio Current, which has a high potential for generating electricity. These currents have speed and consequently kinetic energy and can generate electricity by using turbines installed deep in the ocean. One of the problems that these currents have is that they change over time and therefore the power generation of energy converters of Kuroshio currents also varies. Therefore, the effect of these changes on different aspects of these converters such as reliability should be investigated. Materials and Methods: In the reliability model of the current converter, both the component failure and output power variations, which are caused by the change in the speed of ocean currents are considered. Results and Discussion: In this part, a Kuroshio Current energy converter that includes a turbine with a diameter of 2 meters is considered. In this part, the reliability indices of a sample test system are obtained, and then the effect of Kuroshio Current power plants on these indices is evaluated. The results show that as the peak load of the system increases, the reliability of the system deteriorates. Conclusion: In this paper, the reliability model of Kuroshio Current converters is obtained. Numerical results conclude that the Kuroshio Current converters can improve reliability indices of power system. Manuscript profile -

The reliability of such a system is obtained when strength and stress variables are given by Gompertz distribution with common scale parameter λ and different shape parameters α and . The system reliability is estimated using maximum likelihood estimation (MLE) and the best observational percentile estimation (BPE) methods in samples drawn from strength and stress distributions. Also, the asymptotic confidence interval for system reliability is obtained. The reliability estimators obtained from both methods are compared using mean squares error criteria and confidence interval length via Monte Carlo simulation. In the end, using two real data sets we illustrate the procedure. Before analyzing the data, we first show that the Gompertz distribution is fitted to this data sets using the Kolmogorov-Smirnov goodness-of-fit test statistic. In general, the simulation results show that due to the increase in sample size, the average mean, mean squares error and length of confidence interval in the maximum likelihood method is decreasing compared to the best percentile estimator method. This indicates that the maximum likelihood method is more efficient. Also, in this paper, it was shown that the one out of three component system reliability is more than the one out of two component system reliability for both methods of estimation.

There are number of challenges in WSNs because of limitation of battery power, communications, computation and storage space. In the recent years, computational intelligence approaches such as evolutionary algorithms and swarm intelligence are applied successfully to solve many problems in WSNs. Most important of these problems are data aggregation, energy-aware routing, duty cycle scheduling, security and localization. These problem are in form of distributed so distributed approaches are required to solve them. Reinforcement learning is one of the most widely used and most effective methods of computational intelligence. In this paper, we used the reinforcement learning to solve multicast Quality of Service (QoS) routing. The simulation results showed that reinforcement learning is a suitable approach to solve this problem. The algorithm is implemented easy, it has the great flexibility in topology changes and it leads to optimized results. Distributed reinforcement learning provides compatibility mechanisms that show the intelligence behavior in complicate and dynamic environment such as WSNs. Using reinforcement learning, sensors behave autonomously, independently and flexibly during topology and scenario changes. Manuscript profile -

Practically approaching, this paper devises a new support tool based on a multiattribute decision making (MADM) framework in combination with analytical hierarchical process (AHP) to determine the most critical components of power transmission systems. Measure of system-wide reliability performance, outage cost, Locational marginal prices demonstrative of market fairness, and network losses are among the attributes considered in this paper for component criticality assessment. With the frequent existence of qualitative and quantitative attributes, the proposed approach can effectively help to deal with the existent uncertainty and conventional judgment vagueness. As verified in a case study on the IEEE Reliability Test System (IEEE-RTS), the proposed framework introduces its applicability and efficiency for the practical asset management optimizations in electric utilities.

When a component has the ability to obtain all the situations from completely working to completely failed, it named continues-state component. In the real world, performance rate of elements are continuous and decrease by time. Continuity of components causes infinite working states and grows up the system states. In this paper we propose a new method for series-parallel continues-state RAP2‡using UGF3§for multi-state systems. In this method at first we consider a binary CFR4**system. Using Weibull distribution function for the performance rate of working state, this system upgraded to a CSC. Then the UGF for a series-parallel system has been studied and a numerical example presented to illustrate the reliability and availability computation. Manuscript profile -

Population research, customers of the Bank Persians and EN Bank in Tehran based on sample stage cluster random is number of 270 customers of each bank. Based on data analysis of this research, all factors considered in the on customer loyalty of Parsian Bank and EN Bank was effective and factors of service quality, reliability, speed of service, flexibility, innovation and also studied image were the highest effect on customer loyalty. Also based on this study of samples studied, the reliability of service and image with customers in the Parsian Bank is than better of EN Bank, in other aspects these banks are almost similar conditions. According to research, though private banks in terms of service quality, reliability, speed of service are in good condition and largely have been successful to create the appropriate image in the mind of own customers, but the factors of flexibility and innovation are so important characteristics of organizations to respond quickly, in terms of their customers than other factors are at lower level. Therefore, more attention to use the innovation and flexibility in providing services, it seems necessary to reinforce the strengths and eliminate weaknesses of Private Bank based on these questionnaires; in this study recommendations are presented.

In this paper, we examine the extent of existing gaps between the expectations and the services perceived by the customers of “Police +10 offices” in each of the five service quality dimensions, and then ranking these service quality dimensions on the basis of their relative importance from the customers’ viewpoints. The present research method is applied in its goals and objectives, and is descriptive with regard to the type and nature of the issue, goals, and research questions. We used a surveying method to gather information. All customers of the “Police +10” offices in Tehran form the statistical population of this investigation. Of this population, a statistical sample of 283 people was selected; they were given a standard questionnaire, which is referable in international studies, and the data collected by statistical methods were used for testing the research assumptions. The results of this investigation showed that there are gaps in the customers’ expectations of services and services delivered to them by the “police +10 offices” in all five service quality dimensions. As to the relative importance of each of these dimensions, assurance was the most important dimension, followed in order by reliability, responsibility, and empathy. Tangibles were the least important dimension. Moreover, the largest gap between expectations and perceptions was in tangible dimension, and the smallest gap between these areas was associated to the reliability dimension. Manuscript profile -

And when the demand for computer systems increased, the possibility of crisis and failure of the computer will increase. Thus, the reliability of computer systems has become a key concern for our life. According to The IEEE defines, software reliability is probability of failure-free software operation for a specified period of time in a specified environment. The problem is that currently most accurate method of software has error, and unfortunately still cannot completely prevent all errors. And software maintenance cost and elimination of errors is expensive, and even because of these reasons may be allowed error to remain in the system. This has reduced the reliability of the software. Previous solutions and procedures to enhance software assurance in various elimination forecasting and fault tolerance techniques has problems such as the complexity of formal methods (nominal) single version and version redundancy techniques, testing costs and the reuse of software code changes. The aim of this study is provide a method to increase software reliability and redundancy without the complexity of the software. In this study emphasize on the use of the capabilities inherent in the algorithm to reduce the complexity of software. Manuscript profile -

There are various methods for doing this, such as using moments, maximum entropy, hazard rate, and so on. Nanda (2010) used failure rate and mean residual life functions to characterizing some distributions. In this paper, we extend the results of Nanda (2010). We characterize the Pareto, exponential, and Rayleigh distributions by refining the main results of that paper. We take some inequalities from that paper and propose a new inequality. Then, we raise both sides of the inequalities to some power and show that equality holds if and only if certain distributions are characterized. Manuscript profile -

With the advent of energy management and power consumption methods, the load growth trend has decreased, but there is still a need to optimize the issues of optimal operation in the production, transmission and distribution networks to supply and transfer power from producers to consumers. Therefore, solving the problem of economic load distribution in an optimal way and at an acceptable level of reliability is essential. The main purpose of this issue is to reduce operating costs. Operating costs include the cost of operating power plants and maintaining the network. In addition to cost, there are other goals such as network reliability that have not been carefully and seriously examined, so this article examines these goals. In this paper, a safe multi-objective optimization framework for dispatching power plants is presented. Cost minimization, redistributed energy were considered as optimization objective functions.

The major anxiety in security and privacy is the result of the fact that the topography of important operas can be available to sensitive information. To improve storage in distributed cloud data centers, the Particle Swarm Optimization (PSO) algorithm has been used to copy data between data centers. This paper summarizes the objectives and constraints of the cloud storage problem in order to achieve good performance by considering the shortest data transmission distance, obtaining optimal storage in distributed data centers with reliability based on PSO algorithm between two central data sets. And then it provides an intelligent cryptographic approach that cloud service operators cannot directly access partial data. Numerical results show that the proposed method can provide a good cloud storage strategy when the number of distributed data centers is equal, the defense of the main threats in the clouds can be done effectively.

Expected Unsupplied Energy (EENS) is considered as a criterion for probability and a new method has been proposed to calculate this index in the presence of uninterruptible load. The credibility of issue 1Unit Commitment (RCUC) is expressed mathematically based on linear composition (MIP) programming. The most important economic constraint is the cost of energy. And technically, by considering intermittent loads and rotating reservations, with the help of possible topics, the amount of unsecured energy can be reduced and, of course, the reliability of the units' participation can be increased.

This is a correlational research, in which from 30000 college students associated with the Consultation Department of the Supreme Leader’s Office at universities, 1918 persons were randomly selected. The students completed the original test of Envy Scale (Vali-Zadeh, 2010/1389s.c.). For the validity of the scale, factor analysis methods (exploratory and confirmatory) and concurrent validity were used. Factor analysis of the data showed that the revised form of the Islamic Scale of Envy have four factors (including sense of irritation by others’ success, sense of deprivation and inferiority, tendency to deprive others of their blessings, and sorrow of being compared) and have a good concurrent validity. To avaluate the reliability of the scale, internal consistency was measured by Cronbach’s Alpha yielding 0.93 which means a highly reliable scale. Based on findings of the reseach, it can be concluded that this questionnaire has a high reliability and validity, which can assist us in investigating people’s temperamental and personality envy-related traits and it can be employed for clinical activities and future studies.

Therefore, this study sought to investigate fairness in the context of the Iranian General English University Entrance Examination (Konkoor) to see the extent to which it is a fair measure of the candidates’ English language ability in terms of admission requirements, format, structure, and content. The researchers developed a questionnaire called EUEE, containing two sections: a demographic box and close-ended items with a 5-point Likert-type scale asking respondents to express their opinions. The findings showed that while the majority of respondents agreed that the EUEE met the standards of corporate responsibility and no-test product services, there were significant concerns about its validity, fairness, reliability, test design, equating, linking, norming, cut score, test administration, scoring, reporting, and test takers’ rights and responsibilities.

The selection among the bauxite sources is based on previous exploration data, such as: tonnage, grade, mineralogy, etc., the geographical position of the deposit, existing natural and constructed infrastructure and the distance from deep water ports. Environmental and political risks are also investigated. Decision making is a complex task in which the close co-operation of professionals of the bauxite-alumina industry is needed. The authors specify the most determinant factors which are investigated for decision making and call attention to the fact that, in many cases, inconsistent data are compared as if they were equal in value or identical such as: the reliability of explorations made for deposits in various countries, and at different times is also different, the methods applied in reserve calculation and resource estimate are different, the qualitative criteria used for commercial grade ores are different, no numeric data are available showing the possible error in reserve calculation the terminology used for bauxite categories is also different.Adequate attention is never given for the further development of possible prospects; their investigation may be neglected in the selection. As a consequence, when different resources are compared, the geological risks (stability in bauxite production) cannot adequately be taken into account. For minimizing the transport costs (either the bauxite supply to the alumina plant or the alumina shipping to the smelter or both) the geographical position of the raw material is one of the most significant economic factors in the value of the deposit. There are several regions in the world which are so rich in bauxite potential (West Africa, edge of the Guyana Shield in Venezuela and Brazil, the Amazon Basin in Brazil, Weipa Gove in Australia, Eastern Ghats in India, etc.) where new deposits should be explored as a function of their geographical position. The landsat interpretation has proved to be an excellent tool for establishing priorities among the options. The authors give a short review and comparison of the most significant regions and deposits focusing their interests on the: tonnage, grade and mineralogy, further prospects (undiscovered) deposits, infrastructure, distance from mine/deposits to the deep water ports, available alumina content (for a low or a high temperature procedure) for estimating the bauxite consumption per ton of alumina, soluble silica content for estimating the caustic soda consumption per ton of alumina, beneficiation cost in some cases, risk factors (geological, environmental, political and national) The authors conclude, that in spite of the fact that about 30 - 35 billion tons of bauxite have been registered so far as proved + probable reserves and a further 55 – 60 billion tons can be estimated as possible resources in the world, finding new resources in better geographical locations and their exploration may be advantageous. The new exploration data must be more reliable, as well. The costs of reconnaissance and exploration may be far below the haulage costs. Manuscript profile -

Inventory management is a key element on the performance of the maintenance policy. Through current research, an integrated inventory control of spare parts and maintenance scheduling is proposed to determine the maximum inventory level as well replenishment cycle (S,T), along with the determination of the optimal preventive maintenance period. The total cost associated with the maintenance system, such as the cost of periodical and emergency orders and the costs of inspections and repairs are minimized via the model objective function. To illustrate the capability and performance of the model, the results of applying the model into a case study is reported in an automotive pre-paint line for determining inventory control policies of a critical item. In addition, in order to analyze the stability of the results, the sensitivity of the variables to the changes in input parameters has been investigated. Based on the results, the total cost is affected by the failure rate, the lead time period, and the cost of replacing defective items. In this regard, the system is more sensitive to failure rate and the lead time. In the case of constant failure rates, applying the proposed method might be successful. Manuscript profile -

In this study, the reliability analysis in 110 concrete buildings running in area one of Tehran with the assumption of variable compressive strength of concrete and yield strength of rebar has been investigated. That is, it has compared the flexural frame and the flexural frame with the shear wall. And this is slightly higher in shear walls. Also, in all tested rebar’s (environmentally friendly), the average yield strength was higher than the nominal strength. Regarding seismic performance, shear wall structure has less general and relative displacement than flexural frame structure. The results of reliability analysis showed that the use of shear wall system instead of bending frame can reduce damage to non-structural components and consequently reduce the production of construction debris and preserve the environment.

Among the issues related to machinery, maintenance and repair are very important because maintenance and repairs (machines) are directly related to their costs as well as the overall cost of the project. The repair method after the failure is replaced by other maintenance and repair methods that are currently used in many organizations. Reliable Maintenance and Maintenance (RCM) is a process that determines the maintenance and repair needs of equipment and machinery in working conditions so that each of this equipment performs its core tasks in the best possible manner. Instead of concentrating on cost reduction, this method focuses on increasing reliability, which means that costs have been reduced by improving reliability. Reducing maintenance costs is a good and timely maintenance. In this study, a case study of this method has been carried out during a one-year period at Jahad Nasr Sirjan Company and compared with a sample of Sarcheshme Copper Company, which would be acceptable.

In this study, when the original transcript of MASC was translated into Persian, it retranslated then reviewed for correction and the final form provided for implementation. The participants in this study include 10-16 Year old students (353 girls, 347 boys) studying in Tonekabon. The multi-stage procedure was used to pick up sample (classified and clustered random). To investigate the convergent validity, the students answered the questionnaires in Revised children’s manifested anxiety scale (RCMAS). To control scale reliability, it was utilized Cronbach coefficient. To calculate scale validity, factor analysis was used as main components analysis. To prepare the norm table, there were utilized Z & T balanced scores. Cronbach coefficient also was recorded 0.91 for the total scale. Implementing exploratory factorial analysis through varimax rotation revealed a robust eight-factor structure. Correlation coefficient was significant between the total score in multidimensional anxiety scale in children and RCMAS. The children’s multidimensional anxiety scale showed an appropriate validity and internal homogeneity among Iranian students, therefore it can be used for further studies. Manuscript profile -

Two separate samples were used to perform exploratory and confirmatory factor analysis. The number of samples in the exploratory analysis was 329 people and in the confirmatory factor analysis 250 people. The parents of the students completed the scale of educational expectations and aspirations of the parents. Internal consistency, test-retest, and split-half methods were used to check reliability. Reliability values for internal consistency, split­- half, and test-retest were obtained 0.82, 0.77, and 0.74, respectively. Exploratory and confirmatory factor analysis was used for construct validity. In the exploratory analysis, the range of factor loadings was at an acceptable level. The calculation results of the KMO test were equal to 0.882 and the result of the Bartlett test was equal to 3775.677. In the confirmatory factor analysis were confirmed factors of expectations and valuing education, readiness for academic progress, educational evaluation, and stability of expectations and aspirations. The results of fit indices of confirmatory factor analysis showed that the model had an acceptable fit. Therefore, the scale of educational expectations and aspirations of parents has the necessary psychometric properties for the Iranian sample. Manuscript profile -

The optimal operation of microgrids in the presence of intermittent renewable sources has been counted as a new challenge within the last decade. Microgrids are off-grid or grid-connected power systems on a very small scale encompassing different types of distributed generation sources and local loads. Generally, in isolated microgrids, the demanded energy of consumers is maintained by hybrid models of internal energy sources. The principal purpose of hybrid systems is to supply the electrical power demanded by consumers instantaneously as well as storing surplus energy for critical conditions. In this paper, a techno-economic and environmental base approach for optimal energy management of microgrids using crow search algorithm is presented. Under study microgrid include renewable energy resources, battery and diesel generator as backup power generator. Annual cost and the released emission are considered as the objective function of the proposed method. The crow search algorithm calculates power dispatch scheduling among generation units. Simulation results of the proposed method show the appropriate configuration of the hybrid system that lead to decrease the annual cost of the system and the released emission. Manuscript profile -

Installation of capacitors and distributed generations (DGs) in distribution systems has many benefits, such as improving the reliability as well as reducing the power loss, however, includes high investment costs. Hence, the maximum use of these benefits highly depends on choosing suitable locations for installation. In this paper, the Success Rate Group Search Algorithm (SRGSO) is used for optimal placement and sizing of DG sources and capacitor banks simultaneously in distributed systems. The used objective function includes costs of Expected interruption (ECOST), Energy Not Supplied (ENS), active power losses and DG and capacitor investment, operation and maintenance. To evaluate the effectiveness of the proposed algorithm in finding the optimal solution, various capacitor and DG placement scenarios are simulated on the IEEE 33-bus radial distribution test system. The simulation results show that the proposed method is more effective and has higher capability for solving the problem of capacitor and DG placement, compared to previously proposed methods. Using the proposed method in this paper, the value of active power losses as well as bus voltage profile are improved more than other investigated methods. Manuscript profile -

In this paper a new method for mathematical modeling of failure correlation of parallel transformers using Poisson process and multi-Gaussian Copula function is presented. In this method, by using computation of selected reliability indices and related costs, a modeling method for estimation of expectation value of failure cost of parallel transformers with failure correlation and also cost of annual risk of power system has been proposed. According to the capability of production of stage-gate process of the system real mode and failure correlation and probability of parallel transformers, sequential Monte Carlo method for calculation of system’s reliability indices and related costs estimation has been employed. Simulation results of the proposed method show that annual increase of failure correlation probability of parallel transformers in power stations, will lead to increase of expectation value of their failure, level and cost of power system’s risk.

In this paper, MoreAdvances in power electronic applications, high reliability power distribution systems and flight control propulsion technologies, have increased the utilization of electric power in modern aircrafts. This has led to the concept of more electric aircraft. In this paper, a new structure is proposed to generate the electric power in aircraft. The aircraft power generation and consumption system is modeled as a microgrid. The proposed more-reliable power generation system is based on induction generator, rectifier and voltage source inverter. Induction generator is coupled with turbojet motor. The smart active power sharing between generators is achieved by using improved droop control method. Optimal droop coefficients are assigned by combining mathematical approaches including descending gradient method and minimizing the mean squares of the frequency deviation. The aircraft electrical network is simulated with the proposed controller in MATLAB and its performance is analyzed. The simulation results show the proper power sharing between generators. The advantages of the proposed method over the conventional structure include the elimination of the mechanical constant speed drive which increase reliability and proper power sharing.

In the incentive model for measuring the performance, reliability indices are compared by feeders, and in contrast, the repair program is obtained for each feeder separately. Due to the different causes of feeder failure such as their structural properties and weather conditions, increasing the accuracy of performance comparison from companies to feeders, in addition to penalties and rewards assigning leads to maximise the impact of maintenance at the level of their reliability and is accompanied by cost savings. For this purpose, the information of a real network including 194 feeders is considered as primary data. After categorizing the feeders and calculating penalties and rewards, the profit from the provision of services are optimized by BPSO method. As a result, the preventive maintenance program is obtained separately for feeders for three general categories of frequent failures, which includes substation failure, line failure and tree branch collision in a period of 5 years. The optimization results show that the proposed method, while maximizing the profits of distribution companies, also improves their performance in terms of reliability. Manuscript profile -

In these networks, many topological changes create many challenges for efficient data delivery. The data dissemination method can meet the needs of emergency message broadcasting. Disseminating data on these networks is a complex and vital task because the highly variable speeds of vehicles increase communication gaps. In these networks, fast and guaranteed high delivery of packets is essential. In this paper, a method is proposed in which the dedicated short range communication (DSRC) channel is divided into three different types of priorities for beacon messages. A dynamic receiver is defined for each class to broadcast the message. The technique of considering the intermediate condition between the source node and the sender node is used to prevent the broadcast of redundancy and the optimal use of bandwidth. The proposed method does not require any hardware or central controller. In order to analyze the efficiency, the proposed method is compared with ASPBT and aadaptive data dissemination protocol (AddP) methods. The analytical evaluation and simulation results show that our proposed method is superior to other methods in terms of efficiency. Manuscript profile -

This scheme includes objective function that is minimized the summation of expected operation cost of MG and DGs, expected pollution cost and outage cost in the N-1 contingency. This problem is constrained to AC power flow equations, MG operation and reliability limits, and operation formulation of DGs and ALs including the demand response program (DRP) and battery. Also, this paper uses the stochastic programming to model uncertainties of load, energy price, renewable DGs (RDGs) generation power and Availability of MG Equipment. Then, to achieve unique reliable optimal solution, it uses hybrid solver of ant-lion optimizer (ALO) and crow search algorithm (CSA). Finally, by implementing of the proposed strategy on a standard MG and obtain numerical results, the capability of the scheme in improving technical and economic indices of the MG along with procuring clean and reliable energy is confirmed.

Most of papers and research about TNEP employed N–1 safe criterion to formulate the transmission reliability, while a few of them have considered load shedding (LS) index to meet the required reliability of consumers for electric demand. Thus, an economic evaluation is necessary to clear which of these reliability criteria is more appropriate for transmission expansion planning studies. This paper tries to compare these reliability indices to each other and show that which of them are more economic and better for expansion planning of a transmission system. The aim is to compromise between transmission lines and substations expansion cost, network losses, and system reliability considering maintenance and repair expenses as well as replacement cost of timeworn lines. To formulate the network reliability, first deterministic reliability criterion of N–1 was employed and embedded in the problem formulation and results were discussed, then N–1 criterion was replaced by probabilistic reliability index of load shedding in TNEP formulation and the results were compared with results of first model. Both of TNEP models are tested on well known as Garver’s 6-bus network and IEEE reliability 24-bus test system (IEEE RTS). Manuscript profile -

Transmitting the message in critical situations with minimal delay and on time is essential for ensuring the health and safety of citizens on road trips. Frequent topological changes pose significant challenges to the operation of safety programs and reduce the probability of sending critical messages in real-time. This article proposes the reliable relay node selection to real-time messaging (RRRM) routing algorithm to increase the reliability of sending real-time messages in vehicular networks. To expedite the transmission of information, by introducing three indicators for selecting intermediate vehicles entitled "Record of vehicle displacement", "Similarity of vehicle velocity with the velocity average of neighbor vehicles", and "Amount of trusty adjacent vehicles", the route vehicles are scored. The worthiest vehicles are selected as members of the route. RRRM measures the temporal conformity of the vehicles' previous presence in the current route and the stability of their connection with neighboring vehicles. It avoids route failure, increased delays, and failure to send critical messages to the destination by preventing the selection of unreliable vehicles as relays. Extensive simulations with multiple scenarios in the NS-3 and SUMO demonstrate the superiority of the RRRM in reducing route-failure, mean latency, and control overload, as well as increasing packet delivery rates in urban and highway environments.

Since the buses having first order redundancy degrade the system observability by missing their measurements, this method is used to reduce the number of these. On the other hand, the proposed method, in spite of the previous methods, is used to enhance the system observability by improving the redundancy order of the other low order redundancy buses without increasing the number of the lower orders. .In addition, by using this method, the optimal PMU placement can be obtained considering the contingencies such as PMU outage or line outage. It should be noted that the proposed methods are implemented on the IEEE 14-, 30, 57- and 118- bus power networks. The simulation results are compared with previous methods. In addition, simulations are performed with and without considering the effect of zero injection buses. Manuscript profile -

By altering the status of switches, the distribution feeder reconfiguration (DFR) can reduce system losses in this regard. Power loss and voltage deviation of buses are frequently taken into account as objective functions while solving the distribution feeder reconfiguration problem, however reliability indices have received less consideration. The proposed reliability index, coupled with power loss and switching number in the presence of distributed generators, are used in this study to address DFR as a multi-objective problem. The DFR problem is complex inherently, considering impacts of distributed generators makes the problem more be complex than before. For this purpose, an evolutionary method based on the combination of particle swarm optimization and modified shuffled frog leaping has been used to solve the nonlinear optimization problem in this study. Two 33-bus and 70-bus systems are evaluated to gauge the effectiveness of the suggested hybrid algorithm. Manuscript profile -

Considering the limitation of the wind farms in continuous supply of electric power, hydrostatic power storage facilities are used beside wind farms so that the electric power could be stored and fed in a continuous flow into power systems. Due to the gradual exclusion of conventional generators and 5 percent annual load increments, LOLE index was used in order to calculate the amount of the wind power and the capacity of the necessary power storage facility. To this end, LOLE index was calculated for the first year as the reference index for the estimation of the amount of wind power and the capacity of the storage facility in consequent years. For the upcoming years, calculations have been made to account for the gradual exclusion of conventional generators in proportion to load increments. The proposed method has been implemented and simulated on IEEE-RTS test system. Manuscript profile -

Ḥajjāj's character and especially Sajestāni's narrative of his eleven changes have become an excuse to doubt the authenticity of the Qur’an. In this article, we collected, criticized and analyzed the sayings of Muslim scholars and orientalists with descriptive-analytical method and analyzed what Ḥajjāj did in relation to the Qurʾan and what was his motivation for this work. According to this research, Sajestāani's narrative is acceptable by providing explanations and does not contradict the validity of the Qurʾan. The main work of Ḥajjāj has been promoting the ʿUttomān Muṣḥaf and completing the project of Tawḥīd Muṣaḥaf and eliminating incorrect recitations, especially the recitations of ibn Masʿūd. A goal that Ḥajjāj, like ʿUthmān, could not fully achieve. His motivation was also the love of ʿUthmān and the hatred of the Qariyans and Mawālī for appearing in the war of ibn Ashʿath; A war that was about to destroy not only Ḥajjāj and Banī Umayyad but also the Islamic Caliphate forever.

In this study, 2 and 5-story steel moment-resisting frame structures have been considered under the heavy vehicle collision impact. They are modeled in OpenSees software two-dimensionally with regarding to uncertainty in materials and applied loads and the sensitivity based reliability analysis of the studied random parameters is performed in Matlab software. Then, the effect of each of the variables is investigated using simulation-based methods according to limit state functions based on the maximum permitted beam rotation of damaged bay of frames. The results of this study presented that the random variables such as mass and velocity of vehicle and yield strength of material were the most influential parameters in calculating the failure probability in representative structures. Also, the control variates-based subset simulation (CSS) method compared to Monte Carlo Simulation (MCS) approach estimated the failure probability with permissible error rate, less sample number and the minimum computer processing time duration. Furthermore, the results of this research indicated that by increasing the number of stories of the building, the probability of its failure due to vehicle collision increased. According to the results of this study, the value of beam rotation of damaged bay parameter of the 5-story frame compared to 2-story one has increased by 55, 18 and 33% under the LSF1, LSF2 and LSF3 functions, respectively Manuscript profile -

Therefore, the purpose of the present study is to investigate the quality and failure rate of the parts that provided by the suppliers. In doing so, the evaluation approach based on the failure rate was used and the reliability of the suppliers was determined and their ranking was done. As a result, the research method used is applied in nature and its method is contextual-case. Moreover, for the purpose of a case study, the suppliers of seven separate supply chains of an electrical appliance manufacturing company in Shiraz were examined that each of the chains included eight suppliers. Besides, in order to evaluate and establish the supplier's reliability model based on the failure rate, a parallel system was used. Finally, by calculating the reliability, the failure rate of the supplier's manufactured product was obtained. The results showed that this failure rate is a suitable criterion for comparing the output quality or the products of suppliers. Thus, it is possible to rate the suppliers based on this obtained model. Manuscript profile -

Methodology: the method of this research was descriptive (survey) research, and statistical population of it included all students that enrolled in all branches of Payam-Noor University of Hamedan province. The total number of those were 28530 people. For sampling ofpopulation, a cluster sampling method was used. On the basis of this method, the 387 subjects were selected. For gathering of dada a research-made questionnaire was used. This questionnaire has made based on the Likert scale (very high, high, moderate, low, and very low). The component of scale (questionnaire) included 5 standard competency of ACRL. The questionnaire included 30 items in the form of self-report statements. For becoming suitable of items, the discriminative power method was used and formal, content and constructive (convergent validity and factor analysis) methods were used for validating of it. Based on the convergent validity, the correlation coefficient between my questionnaire and Asgharnia’s Questionnaire (2009) was 0.77. Also, results of explanatory factor analysis on the items of questionnaire lead to extraction of 6 factors with a total cumulative variance explained nearly 66/5%. Also, on the basis of confirmatory factor analysis, the 5 factors with a total cumulative variance explained nearly 63%, were extracted. For making items reliable, the Cronbach’s alpha was used (α=0.94). Findings: in general, results show that the research-made scale (information literacy questionnaire) is a suitable and reliable instrument for assessing the information literacy of distance learner. Also, other result of research shows that the level of students’ information literacy skills at Payam-e-Noor University is moderate. Conclusion: one of the results of this study was that the instrument (scale) is valid & reliable, so using this scale is proposed for assessing of Students’ Information Literacy at other branches of Payam-e-Noor University. Another result of research was that level of students’ information literacy in PNU isn’t desirable and there is a gap between status quo and desirable situation; therefore some interventions (such as: formal and informal instruction) for rising of students’ information literacy is proposed.

The sample of the research consists of 94 companies listed in the Tehran Stock Exchange during the years between 2004 to 2012. The results of theoretical research suggested that auditor’s tenure may influence on the quality of information disclosure through an effect on the auditing quality and independence. To measure the variable of disclosure quality, the advantages of each company are utilized. These advantages have been extracted by Tehran Stock Exchange Organization through notifications on the quality of information disclosure and proper informing. The aim of this study was to investigate the relationship between auditor tenure and disclosure quality with the use of multiple linear regression analysis and the separation of auditor tenure duration period into two short-term and long-term periods. The results indicated the existence of a significant and positive relationship between auditor’s tenure and disclosure quality. In other words, an increase in auditor’s tenure duration period will substantially lead to an increase in the disclosure quality. Manuscript profile -

To develop such scale, 442 female (N = 249) and male (N = 193) university students were administrated a researcher-devised questionnaire, originating from Objective Measure of Ego Identity Status (Adams, Bennion & Hugh, 1989, Adams, 1998). The structure and content of scale were analyzed, using the Smallest Space Analysis (SSA) technique. Internal consistency was assessed by Cronbach’s alpha coefficient. Findings suggest the accuracy of four identity statuses of the questionnaire (achieved, moratorium, foreclosed and diffused) derived through internal consistency (alpha coefficients ranged from 0.77 to 0.85), and the reliability of Marcia’s theoretical model (1966) of ego identity (exploration and commitment) for measurement in Iranian culture. Content and structural analysis of ego identity made possible the identification of all above mentioned status of ego and showed that the constituted areas of identity status were clearly distinguishable. Data suggest that the developed scale of Ego Identity Measurement can be a reliable instrument for measuring ego identity in both genders. Manuscript profile -

Two hundred and eighty nine undergraduate students (143 females, 146 males) were selected from different disciplines of Tehran University using convenience sampling. The guilt subscale of the Personal Feeling Questionnaire (Harder & Zalma, 1990) and the Chronic Self-Destructiveness Scale (Kelley, et al., 1985) were used for studying divergent validity. The results indicated that the WUSCT had appropriate internal consistency (ranged from 0/118 to 0/326). The Cronbach α and 2-weeks test-retest reliability were .781 and .876, respectively. The negative correlation of the WUSCT with self-destructiveness demonstrated the divergent validity of the WUSCT. The WUSCT could discriminate the group with high ego development from the group with low guilt and self-destructiveness which indicated the discriminant validity of the WUSCT. The factorial analyses indicated that the WUSCT was unidimensional. The findings suggest that the Persian version of the WUSCT is a valid and reliable tool for assessing ego development.

Three hundred university students (156 males, 144 females) completed the MPCI-E and the Positive and Negative Affect Schedule (PANAS; Watson, Clark, & Tellegen, 1988). The exploratory and confirmatory factor analyses and internal consistency were used to assess factorial validity and reliability of the MPCIE, respectively. The divergent validity of the MPCI-E were assessed through correlations between MPCI-E scales and past-week positive and negative affect. The results of principal component analysis (PC) and oblique rotation indicated that the MPCI-E consisted of three factors: personal standards, concern over mistakes, and pursuit of perfection. Goodness-of-fit indices of confirmatory factor analysis confirmed the three extracted factors. A differential pattern of significant correlations between the MPCI-E and positive and negative affect demonstrated divergent validity of the MPCI-E. Internal consistencies of the MPCI-E subscales were good. In sum, these findings provided evidence for the validity and reliability of the MPCI-E as a multidimensional measure of perfectionism cognitions in Iranian students. Manuscript profile -

Test of the internal con- sistency of the OHI revealed that all 29 items were highly correlated with the total score. The Cronbach’s alpha for the inventory was 0.91. The Pearson’s correlation coefficient between the OHI and the BDI and Extraversion and Neuroticism of EPQ subscales were respectively -0.48, 0.45, and -0.39, confirming their convergent and divergent validity. Factor analysis extracted five factors including life satisfaction, self-esteem, subjective well-being, self satisfaction, and positive affect, with an eigenvalue of greater than one that could explain 49.7% of the total variance. The Iranian participants’ mean score on the OHI (M = 42.07) differed from that of participants in the Ar- gyle’s study (M = 35.6). The results showed that the OHI is a reliable and valid inventory for measuring happiness among Iranians. Manuscript profile -

The coefficients of internal consistency and test-retest reliability, done in a 4 week interval, were 0.89 and 0.75 respectively. Results of principle component analysis using Promax rotation and confirmatory factor analysis revealed that the structure of the D-39 scale contains the following factors: diabetes control, energy and mobility, social burden, anxiety and worry, diabetes complications and other illnesses, and sexual functioning. These factors accounted for almost 64% of the variance. A significant negative correlation between the total score of the D-39, scores from its extracted sub-factors and the psychological well-being subscale of Mental Health Inventory confirmed the convergent validity of the scale. Differences among factors in the original scale and the Farsi version are discussed based on the age range of patients. Manuscript profile -

The participants completed the School Maladjustment Scale. Examining the item-total correlation led to elimination of 23 items. The results of principle components analysis and varimax rotation indicated that 24 items had factor loading less than 0.3, so these items were eliminated. The Cronbach's Alpha reliability coefficient for 88 item scale was 0.979. The results of factor analysis led to extraction of six factors: 1) academic indifference and lack of attention, 2) inappropriate behaviors toward teachers and classmates, 3) destructive and indiscipline behaviors, 4) bullying and antisocial behaviors, 5) deception and violation of rules, and 6) withdrawal and victimization by bullies, which explained 57.80 percent of the total variance. The concurrent validity of the scale using comparison to the Student Adjustment Inventory (Sinha & Singh, 1993) was 0.405.

Participants included 278 adults (209 females and 69 males; mean age = 28.65, SD= 9.40) from Shiraz. They completed the questionnaires electronically. To check the validity, after a pilot study and doing backward translation, the Persian version of this scale was provided to the participants. The factor structure of the scale was examined by AMOS-22 software. The results confirmed that there are four factors in the Persian version. Also, factor loads and Fit Indices were desirable. Convergent validity was assessed by the correlation between the scores of this scale and the Short Form of the Self-Compassion Scale (Raes, Pommier, Neff & Van Gucht, 2011). The results showed a moderate correlation between the two constructs. The results of the internal con- sistency study by calculating the correlation of subscales with each other and the total score also indicated the construct validity. Cronbach’s alpha coefficient showed the scale (alpha= 0.82) and subscales (minimum alpha= 0.58) have acceptable reliability. A comparison of gender differences showed that women have higher scores in the kindness subscale. In general, according to the findings, it can be concluded that the Persian version of the Compassion Scale has psychometric adequacy and can be used in Iranian society. Manuscript profile -

H MoreIn the microgrids, it can be used from the renewable energy resources (RERs) such as photovolta-ic panels, wind turbines, wave energy converters and current type tidal turbines to reduce the greenhouse gas (GHG) emission arisen from fossil fuel-based generation units. However, the generated electrical power of these RERs are dependent on the wave height and wave period, solar radiation, the wind speed, and the tidal current speed. Due to the wide variation in the RERs, the generated electrical power of these generation units changes a lot and so, to supply the local load in the isolated microgrid, the conventional generation units and the energy storage sys-tems (ESSs) can be utilized. In this paper, optimal scheduling of a microgrid containing conven-tional generation units, ESS and RERs including wind turbines, photovoltaic panels, current type tidal turbines and wave energy converters is performed to determine the generated power of each generation unit provided that the cost function is minimum. In the cost function, the operation cost of the generation units based on fossil fuel and the penalty cost associated to the load cur-tailment as the reliability cost are considered and using of the particle swarm optimization (PSO) algorithm, the cost function is minimized. To study the capability and effectiveness of the pre-sented approach, the numerical results associated to the optimal scheduling of a microgrid con-taining battery, RERs, and conventional units are presented.

However there is no consensus among virtue epistemologists regarding the general nature of the intellectual virtues. While some scholars such as Sosa consider these Virtues to be a kind of innater competence and cognitive talents, , other scholars such as Zagzebsky view intellectual virtues as intellectual character traits and a subset of moral virtues. Using an analytical approach this study set out to investigate the nature of intellectual virtues from both perspectives. While epistemic reliablism consider intellectual virtues as a kind of innate skill or cognitive faculty enabling individual to be epistemologically efficient, analyses suggest that so far as the concept of praise is deemed necessary in the epistemic analysis of the agents, and so far as the achievement and expansion of avirtue is considered out of control of the epistemic agent, it would be a better option to reject the understanding of intellectual virtues as skilles and innate cognitive faculties, and accept that the character- based approach provide a batter account of the nature of intellectual virtues by considering motive and reliability as two essential criteria for the presence of these virtues, that are admirable charater traits sufficiently by the agent.

In general, the field of activities of companies is very various and these are always faced with so many economical events, so it is not possible to define some specific regulations for reporting those events. In this case, there is an emphasis for financial statements preparers to apply professional judgment in accounting standards. In this study, we are going to elaborate whether the application of professional judgment in Iran accounting standards will affect the quality of financial information such as comparability and reliability of them? And if accountants intend to change the financial information for his benefit, does the professional judgment let them to do that and work as an appropriate tool for their goals? For considering the subject of this research, we have used a combined design in order to measure the effects of financial statements preparers’ decisions on comparability and reliability of the information by using professional judgment. The empirical evidences have been collected to demonstrate whether the level of applied professional judgment in Iran accounting standards, can have any influence on comparability of financial statements. Findings of this research show that using professional judgment in accounting standards will decrease comparability of financial reporting. Empirical findings of this research show that the accountants which are put in an suitable circumstance for moral hazard in comparison to other people who are not in such situation, use their professional judgment to demonstrate better performance for their company and gain more benefits.

This paper proposes a comprehensive reliability model for the FC-MCR using the Markov process approach. The modeling process adheres to actual operational principles and divides the MCR structure into two sections: electro-magnetic section and core magnetization section. Subsequently, the Markov models proposed for these sections are integrated with the Markov model of the fixed capacitor bank to derive the FC-MCR reliability model. Recognizing the impact of environmental conditions on electrical equipment failure rates, the proposed reliability model takes into account temperature variations and assesses their influence on the probabilities of the FC-MCR operating state. By examining the simulation results and conducting sensitivity analysis, it was found that the availability of the FC-MCR is influenced by various components and environmental conditions, which necessitates different reliability enhancement measures. Moreover, a comparison between the reliability indices of the FC-MCR and its counterpart (FC-TCR) in diverse environmental conditions revealed that the FC-MCR is less affected by temperature variations compared to the FC-TCR.

Due to wide change in these quantities, produced power of these renewable resources changes a lot over time. As the penetration level of renewable resources in electric network is increased, reliability and other aspects of electric network may be affected that should be studied. Analytical method is not suitable to study uncertainties of output power of renewable resources in reliability analysis of electric network with these renewable power plants. Thus, the current research suggests Monte Carlo simulation method to study effect of renewable power plants on reliability indices. Renewable power plants studied in the research are wind turbines, solar farms, wave energy converters, run of the river power plants, both types of tidal units, and ocean thermal energy conversion systems. Numerical studies are performed on test electric networks, to study these renewable resources impact on reliability indices of electric networks with renewable power plants. It is concluded from numerical outcomes that these renewable power plants improve reliability performance of electric network. However, due to the variation of renewable resources, the impact of renewable power plants on reliability performance of the electric network is less than the conventional units with the same capacity.

The number of articles published on traditional medicines and their applications is rapidly increasing. However, despite the extensive ongoing research on herbal medicines, the results of such research are not remarkable. Against this background, this study aims to highlight some existing research gaps, the bridging of which will increase the quality and validity of the results of herbal research. To this end, Iranian and non-Iranian articles on Allium sativum L. were reviewed for compliance with standards and requirements for herbal research. Botanical nomenclature, processing and extraction procedures, and history of traditional medicine were identified as the main gaps in the reviewed herbal research. Researchers and authors should keep in mind that familiarity with the history, characteristics, and potential of traditional medicine systems is a key factor accelerating the process of developing nature-based medicines. Essential standards that have a great impact on the validity and reliability of the results of herbal research should not be ignored, either. In addition, there are still numerous areas that need to be considered by scientists and researchers, including the status of medicinal herbs, toxicological assessments, biological and pharmacological mechanisms of diseases, and research issues.

The present study uses the descriptive method that was carried out with the aim of intercultural comparison of resilience. Sample population included all of the university students of Tehran. 400 students were chosen through cluster sampling. Evaluation tool was the resilience questionnaire (Connor-Davidson, 2003) that was analyzed by factor analysis after completion by students. Findings showed that the resilience construct has a proper validity and reliability and includes five factors of purposivism, self-control, problem solving ability, belief and optimism. A comparison of the obtained results with the factor analysis results of the questionnaire in other countries (Spain, India and South Korea) showed that: the number of components and the questions related to each component of resilience construct is different in different countries. In addition, the purposivism and ability to self-control are more important in Iranian culture. So, intercultural differences should be taken into account while considering the resilience of people.

To this end, a number of 403 men and women individuals from the staff of these companies were selected through multistage random sampling. The entire participants were tested and evaluated using the long form (100 questions) of Minnesota job satisfaction questionnaire. This is an exploratory descriptive survey type of research in correlation directory studied based on the classic methods of psychometrics. Using the Cronbach’s alpha coefficient, the validity values of internal consistency of internal and external factors of job satisfaction questionnaire were derived at 0.971 and 0.971 for 61 and 37 questions, respectively. The validity coefficients for the entire questionnaire of Minnesota job satisfaction were calculated at 0.983 following the removal of two questions in the factor analysis (98 questions). Structural reliability of questionnaire was studied using factor analysis and the KMO indicator was equal to 0.935 while the significance of Bartlett’s sphericity indicated the presence of necessary conditions for application of factor analysis. Results of factor analysis through varimax rotation led to extraction of two factors that explains nearly 43% of the total variance. The first factor (internal factor) and the second factor (external factors) constitute 22.889% and 19.842%, respectively. Ratings percentage was calculated in order to draft the norm for job satisfaction questionnaire and as a result, the table of norm was drawn up for both factors and the entire questionnaire. Results of this research suggest that the Minnesota job satisfaction questionnaire may be used as a relatively valid and reliable means for measurement of occupational satisfaction in industrial units.

The study method is descriptive and correlation research for the analysis of covariance matrix. Data were collected from 402 students of high school in 2017-2018 by stratified-cluster sampling. To determine the factorial validity, Confirmatory factor analysis (CFA) and exploratory factor analysis (EFA) were used. In order to determine the internal consistency, Cronbach's alpha coefficient was used. The findings showed that Bam's theoretical model was not fitted with collected data, In contrast to the obtained model from exploratory factor analysis showed acceptable fit with data. The Cronbach alpha coefficient in the whole inventory, the masculinity and femininity subscales was respectively 0.70, 0.70 and 0.61. The results of the research repeated the findings of some previous studies about the BSRI-dependent culture and the extraction of a different factorial structure than theoretical logic. Regarding the non-fit of Bam's theoretical model, the inappropriate patterns of the coefficients in some items and the low correlation of some items with the whole scale, the BSRI Form 30 should be revised to evaluate the gender characteristics of Iranian adolescents Manuscript profile -

The thought of early Rijāli scholars recount the Rijāli evaluations taken from and influenced by the Imams' opinions about the companions. Mohammad ibn Isa Ubaid is of influential textualist Rijālis whose al-Rijāl used to be a source for Mohammad ibn ʿUmar al-Kashī in authoring his Rijāl. This research is to come to an understanding of Ubaidi's Rijāli thought. Therefore, the criterion for reliance or weakness in the two general groups is complimentary or reproaching reactions of the Imam toward the narrator as well as the latter's characteristics, in each of which group there's a meaningful relationship with the type of the criteria. In disagreement points, it does not contain any weak Rijāli leaders (Mashāyīkh). It has preferred scientific relations to in-sectarian disagreements. Whatever is gathered here is an outcome of a geographical stretch of Iraqi school as well as the works of Fataḥīs, Ghulāt, Wāqifīs and weak and reliable narrators, also works unrelated with Rijāl such as Nawādir.

Their mechanical properties due to the variety of materials used, the quality of construction, and the effect of the passage of time can be inconstant and have significant uncertainties. Therefore, to ensure the ability and performance of the structure against the loads, especially earthquakes, adopting more accurate modeling methods and considering these uncertainties is fundamental issue of structural engineering. For a stone arch bridge of Iran's railway network, the mechanical properties of the materials including the normal and shear stiffness coefficient of the stone block joint as well as the internal friction angle of the joints were considered as quantities with uncertainty and as random variables. According to the discrete environment of the bridge, incremental dynamic analysis has been performed under the influence of eleven selected earthquake records using the discrete element method. After analyzing more than 2,600 bridge samples with different material properties, based on the response surface method, the limit state functions of the bridge failure in terms of three random variables have been determined for all records. Using FORM and MSC reliability methods, the reliability index and probability of bridge failure were calculated. The results showed that for the selected earthquake records, the spectral acceleration of the bridge collapse threshold were reduced by 30% to 50% considering the uncertainties compared to the case where the uncertainty in the materials is not considered.

The quantitative data collection part of the present study is a quantitative research that descriptive research methods of normative type will be used. In this study, the excitability scale for appropriate subsequent measurements in Iran; Was standardized. Therefore, this research is an applied research. The results showed that the overall average of excitement in teaching was higher in female teachers than male teachers. In the present study, Cronbach's alpha coefficient was used to calculate the reliability of the Excitement Questionnaire in the teaching of elementary teachers. The Cronbach's alpha range was between the boredom subscale (0.902) and the pride and pleasure subscale (0.537). Cronbach's alpha for general excitement is 0.875, which indicates the reliability of the questionnaire for teachers. Confirmatory factor analysis method was used to measure the excitement in the teaching of elementary teachers. For this purpose, to determine the suitability of the data for factor analysis, KMO coefficient and Bartlett test were used, which showed the suitability of the sample for research. The results showed that five factors with eigenvalues higher than 2 were extracted, which explained 55.365% of the total variance of the factors. Manuscript profile
