Authors: Ahmadi Z. , Haghighi M. , Validi Z.
Published: March 2022

Energy consumption is a significant factor in wireless networks with battery-powered nodes and transceivers as a dominant energy consumer .Also mutual exclusion is a fundamental problem in distributed systems.“Mutual exclusion” allows only one process at a time to access the shared resource and the others have to be locked and wait for their turns.. Retaining mutual exclusion, is proposed as a solution to guarantee the correctness of read/written information from/in the shared resource or critical sections (CS).Wireless Network is an unstable network formed dynamically by a connection of wireless mobile nodes without the use of an existing network substructure. Since energy consumption during communication is a major depletion parameter the number of communication must be reduced as much as possible to achieve extended battery life. Since battery technology does not grow as rapidly as CPU or memory does so there is a strong need for the presence of protocols which are as energy efficient as effective.In this paper we present a new fully distributed token–based mutual-exclusion algorithm for clustered Mobile ad-hoc network with message count reduction purpose which eventuates to power optimization. Therefore we use Raymond's algorithm (which is well-known in stepping down message complexity) within the clusters and perpetual Mobility of token (that is so efficient in high load network such as Manet's) between the clusters.

Authors: Alaghband Mariah
Published: March 2022

Before emerging internet and data network, remote communication had a clear meaning: Telephone (telegraph before it) was the only technology that allowed people to communicate by voice from remote distance. After 1960, fax and data were presented in Public Switched Telephone Network (PSTN). Recently, remote communications have been developed and they include data transmission, video conference, email, instant messages, web browsing and potential for transmission of multimedia content. Today, consumers think about two categories of products and services relating to communications. Tendency of consumers to purchase communicative applications or equipment has growingly become pervasive as products and services and the used technology for remote communications has changed to great extent during 50 years ago. Using semiconductors and digital electronic devices in telecommunication industry could replace analog sound with images and video. Then, switching circuit was completed and it should be more unlikely substituted with packet switching. All these changes indicate a new definition of remote communication: The communication is a group of technology, devices, equipment, installations, networks and software programs that support telecommunication. It has been tried in this paper to identify important parameters and criteria in communication field by utilization from Analytical Hierarchy Process (AHP) technique to interpret suitable platform for presentation of communicative services for subscribers and by recognition and dividing platforms in which there is potential for giving services to the subscribers.

Authors: ShamsiNejhad Seyad Said , Dehnamaki Maedeh , Mehdiabadi Amir , Shahabi Vahid
Published: March 2022

Banking plays an important role in the economy of any country. The success of a healthy economy depends on a robust and healthy banking system. Savings, investments, production, employment and growth in the national economy are affected by the operations and decisions of the banking system. Lending is one of the main activities of most banks and this is affected by risk. Changes in economic conditions affect bank risk. The borrower's credit status may deteriorate over time due to various factors. Credit risk and its management at the branch level can greatly assist banks' performance. Paying attention to credit risk indices at bank branch level is an issue that has been less addressed. In this study, the researchers have prioritized the evaluation of branch-level indicators using new decision-making techniques, such as SWARA and MABAK, by presenting a general model of the factors influencing credit risk at banks level. We first obtained the weight of the indices using the SWARA technique and using the opinions of ten banking experts and then we are ready to enter the MABAK model. The analysis was carried out in qard al-hasan RESALAT Bank, and in 30 selected branches of the bank.

GIS Modeling of Earthquake Damage Zones Using ETM Data and Remote Sensing- Bojnoord, Khorasan Province.
Authors: Farahani Meysam Davoodabadi , Shahsavari Hamideh
Published: March 2022

The devastating earthquake that occurred in Khorasan Shomali Province, Iran, on the 12th May 2008, caused widespread damage and devastation to rural communities and economy. The terrain of the entire region has been weakened and is now highly susceptible to long-term slope instability that will trouble this region for many years to come. Methodology: However, the actual intensity caused by the earthquake ranged between VIII and XI. The seismic intensity map is practical for regional guidance but lacks the detail to provide an adequate representation of the true damage level, in terms of current status and future potential in such a seismically active and populated region, especially when the hazards and risks are likely to be multiple and cascading in high relief areas. Results: This paper presents a GIS-based approach to earthquake damage zone modeling using satellite remote sensing and DEM data. The novelty is to take into account the coseismic ground deformation as an important modulating factor in modeling the susceptibility of earthquake-related geohazards, together with conventional multicriteria factors which draw on geological and topographical variables such as rock competence, slope, proximity to drainage, and fracture density. The modulating effect of the earthquake greatly enhances the susceptibility in the areas where the majority of the ensuing landslides and debris-flows actually took place. Conclusion: When this susceptibility model is further modulated by the mapped surface disruption caused by the earthquake, it is directly linked to seismic intensity and we call it “earthquake damage”. The output earthquake damage map represents both the current damage status as well as the future damage (hazard) potential.

Published: March 2022

In order to benefit maximally from positive features of Distributed Generation (DG) supplies, the finding of location (siting), and determination of optimal capacity of these supplies are inevitable in power distribution networks so that the researches indicate that if this important process is not considered in installation of DG supplies, not only the given positive goals and features are not fulfilled in installation of DG supplies, but also it is probably led to the worse status in installation of power supplies than the past as well. As a result, determination of optimal size and position of power distributed generation supplies is assumed as an important point. An analytical technique has been proposed in this essay for siting and sizing of DG supplies. Technical and economic aspects have been simultaneously considered in the aforesaid method and it is aimed at maximization of profit due to installation of these supplies. Initially, all parameters have been expressed as a function of DG power and then the optimal siting and sizing of DG is determined by employing the suggested method. The studied supplies are of wind and solar types. Simulations are implemented in MATLAB software and the studied systems include IEEE standard 33 and 69- bus networks.

Authors: Mostafaei Shahriar , Moshiri Seid Rahim
Published: March 2022

To date, a majority of geographers have attempted to define the manifestations for convergence between natural phenomena and human's social and behavioral activities. With regard to the results of previous studies in this context, this study seeks to examine and analyze the extent to which geomorphology and its dependant forms affect human culture. In this regard, the culture which evolves under influence of geomorphologic capabilities within the regions has been considered as an organism with various organs.  As known, the culture can be influenced of various components such as religion, politics, economy and so forth. Yet, this study seeks to define how cultures can be affected by geomorphologic visions within regions; this can be rooted in ecological thinking or ethology. In doing so, to define and approve our idea in this study, views and theories of geographers have been used as  the reference model, so that analysis of them has paved the way to theorize human culture and how it is affected by geomorphology. In addition, an area as research location in Paveh County, Province has been considered for data collection through field study, through which suitable outcomes have been obtained.

MLP Based Islanding Detection Using Histogram Analysis for Wind Turbine Distributed Generation
Authors: Ghadimi Hassan , Ebrahimian Homayoun
Published: March 2022

Due to increase distributed generations, Islanding is an important concern for these resources. Personnel and equipment safety issues are main reasons to detection of islanding. Several techniques based on passive and active detection schemes have been proposed previously. Although passive schemes have a large non-detection zone (NDZ), concerns have been raised about active methods because of their degrading effect on power quality. Reliably detecting this condition is regarded by many as an ongoing challenge because existing methods are not entirely satisfactory. This paper proposes a histogram analysis method using a Multi Layer Perceptron (MLP) Neural Network approach for islanding detection in grid-connected wind turbines. The main objective of the proposed approach is to reduce the NDZ and to maintain the output power quality unchanged. In addition, this technique can also overcome the problem of setting detection thresholds which is inherent in existing techniques. The method proposed in this study has a small non-detection zone and is capable of detecting islanding accurately within the minimum standard time. Moreover, for those regions which require better visualization, the proposed approach can serve as an efficient aid for better detecting grid-power disconnection.
Wind Energy Uncertainties in Multi-objective Environmental/Economic Dispatch Based on Multi-objective Evolutionary Algorithm
Authors: Hosseini Firouz Mansour , Ghadimi Noradin
Published: March 2022

This paper a Multi-objective Honey Bee Mating Optimization (MOHBMO) is proposed for Environmental/ Economic Power Dispatch (EED) problem. This paper proposes a new environmental/economic load dispatch model that considers cost and emission function coefficients with uncertainties and the constraints of ramp rate. Due to the environmental concerns that arise from the emissions produced via fossil-fueled electric power plants, the classical economic dispatch, which operates electric power systems so as to minimize only the total fuel cost, can no longer be considered alone. Actually, EED problem is the scheduling of generators which fulfill the load demand of the power plants using fossil fuel and also making combined production, in order for them to perform with minimum cost and emission. Therefore, by EED, emissions can be reduced by dispatch of power generation to minimize emissions. Which is affect on power generated, system loads, fuel cost and emission coefficients in real-world situations. The MOHBMO technique has been carried out on the IEEE 30- and 118-bus test system. This technique is compared with other techniques which reveals the superiority of the proposed approach and confirms its potential for solving other power systems problems.

Authors: Rais Rohani Anahid , Bastanfard A’zam
Published: March 2022

By 2000, sentiment analysis had been only studied based on speech and changes in facial expressions. Since then, studies have been focused on text. Concerning Persian text mining, studies have been conducted on the methods for extracting properties for classification and examination of opinions on social websites with an aim to determine text polarity. The present research was aimed to prepare and implement an algorithm for Persian text sentiment analysis based on the following six basic emotional states: happiness, sadness, fear, anger, surprise, and disgust. In this research, sentiment analysis was carried out using the unsupervised lexical method. Lexicons are divided into four categories, namely the emotional, boosters, negation, and stop lists. The algorithm was written in six different ways using different properties. In the first method, the algorithm was capable of identifying an emotional word in a sentence. The sentiment of the sentence was determined based on the given emotional word. However, it should be noted that the text itself is also important for sentiment analysis because in addition to the emotional words, other factors (such as boosters and negating factors) are also present in the sentence and affect the text sentiment. Hence, the algorithm was enhanced in the subsequent methods to detect the boosters and negating words. Results of running the algorithm using different methods indicated that the algorithm accuracy increased with an increase in the number properties involved. In the sixth method, an algorithm capable of identifying emotional, boosters and negative words was applied to two data samples including sentences written by typical users and sentences written by university students on an electronic learning social website. The accuracy of the algorithm with 100 data samples from typical users and 100 data samples from university students was 80% and 84%, respectively.

In this paper, we evaluated seismic performance properties of steel plate shear wall (SPSW) using Consecutive Modal Pushover Procedure (CMPP). This method is performed on 3, 6 and 9-story SPSW frames subjected to seven earthquake records which are scaled according to ASCE/SEI 7-05 provisions. We conducted nonlinear time history analysis (THA) to verify extracted outputs. The SPSW models indicate a relatively accurate estimation in nonlinear story drift and story displacement response of pushover procedures compared to that of the THA with respect to responses like shear story; while, in the high-rise model in specific, the deformation parameters are more accurate through an increase in the height of the models.

According to limitation of resources of earth, provision of health food security of growing population of the world in a way to have the least destruction in environment is considered as of the most importance. The present study aims to determine amount of concentration of heavy metals of zinc and cadmium in main squares of Meshginshahr City. In this research, to investigate position of concentration of heavy metals of zinc and cadmium in main squares of Meshginshahr Town, first position of sampling from soil and plants in main squares of Meshginshahr City was determined and eight squares were selected. Data obtained from this research was statistically analyzed by SPSS software. Pearson Correlation Test was used to determine correlation of samples and one-sample t-test to consider meaningfulness of samples, Kolmogrorov-Smirnov Test to determine normality of data and variance analysis test to investigate average of concentration of data were used. Results indicated that amounts of concentrations of heavy metals of zinc and cadmium in measured squares were less and standard limit of FAO and so it was meaningful. Also, results of Pearson Correlation Analysis did not indicate a meaningful relationship between amounts of concentrations of heavy metals of zinc and cadmium in soil and plants. Also, results of analysis of data variance indicated that there is not a meaningful difference between metals in soil and plant.

Since the adverse effects of each accident is subordinated to its direct severity, in studies of the traffic safety, has been tried a lot for providing the severity models to identify the severity factors of the adverse effects of the accidents. In this research, the modeling of the pedestrian accidents severity has been evaluated by using the dual logistic regression and three methods. In the number one and two methods, the relationship between the independent variables and the dependent variables respectively was investigated separately (Enter method) and integrated in the model (forward stepwise method). In the third method, first the primary independent variables have been reduced to the fewer variables by using a multi variables statistical method as the analysis to factors method, the variables and then the new variables relationship with the dependent variable, was analyzed by using the logistic regression. The dependent variable in the following models is the pedestrian accidents severity in two injury and fatal categories.

One of the important methods of welding is submerged arc welding. Special features of this method give it an important position among other ways. Prediction the mechanical features of materials in welding zone is known as an important subjects in mechanical science. As the quality of welding has a direct relation with mechanical properties of materials, studying and predicting the factor of quality is very important. Certainly bead width is one of the effective factors because it shows chemical effects and metallurgical structures and micro structures. The most important property of this research is representing an empirical formula with high accuracy for modeling the bead width as an factor of quality of welding in submerged arc welding in which the input factors of arc voltage, current, nozzle to plate distant, welding speed, and the thickness of ZnO Nano particles. On this research central composite rotatable matrix method is used in five level-five factor.  For achieving this empirical formula with high accuracy RSM is used.
