Introduction: the Restoration of endodontically treated teeth is critical, and the Awareness of stresses developed by oblique and vertical forces in restorative methods take a great role in treatment plans. Due to the anatomical shape and inherent form of the stress distribution premolars, could be lost by fractures. Some fractures such as vertical fracture which is probable in...
the methods which are used to analyze microstrip antennas, are divited into three categories: empirical methods, semi-empirical methods and full-wave analysis. empirical and semi-empirical methods are generally based on some fundamental simplifying assumptions about quality of surface current distribution and substrate thickness. thses simplificatioms cause low accuracy in field evaluation. ful...
This paper deals with the application of a multi agent system (MAS) for service restoration in distributed power systems. In this paper, the part of the service restoration process which deals with restoring power to consumers in case of an outage, is considered. A restoration strategy based on agent technology has been formulated. This strategy proposes a method for prioritizing certain consum...
Absrracf This paper develops a coarse-grain parallel genetic algorithm for solving a service restoration problem in electric power distribution systems. Power utility performs service restoration in order to restore out-ofservice areas at fault. Developing effective service restoration procedure is a cost-effective approach to improve service reliability and to enhance customer satisfaction. Th...
Analytical Approach for Active Distribution Network Restoration Including Optimal Voltage Regulation
in this paper, simultaneous placement of distributed generation, capacitor bank and protective devices are utilized to improve the efficiency of the distribution network. the objectives of the problem are reduction of active and reactive power losses, improvement of voltage profile and reliability indices and increasing distribution companies’ profit. the combination of firefly algorithm, parti...
In this paper, effect of the islands number variation in restoration process is investigated and a graph based method for determination of optimum islands boundaries is presented. Also, the effect of number and location of black-start units on the restoration process is evaluated. In optimization process, objective function is minimizing Energy Not Supplied (ENS) and constraints are voltage mar...
abstract the main purpose of this study was to investigate whether there was any significant difference between the speaking achievement of learners who were trained by means of consciousness raising of sociolinguistic skills and that of learners who were trained without the above mentioned task. the participants of this study consist of 60 intermediate level students participating languag...
This paper presents a reactive tabu search for distribution load transfer operation. The load transfer operation at steady-state operation and planning aims at reconfiguring the target network for various purposes including loss minimization. On the contrary, the operation at restoration is called service restoration and aims at minimizing out-of-service area as quickly as possible. Both operat...
