29 Published By: Blue Eyes Intelligence Engineering & Sciences Publication Pvt. Ltd. AbstractThis research verify and describes a Virtual Reconfigurable Circuit (VRC) that designed and implemented for a Fault Tolerant Evolvable Hardware (EHW) system used to calculate the thermal power output of Egypt’s second Training and Research Reactor (ETRR2) during operation. This circuit have three measur...
Conventional fault location methods using voltages and currents of one terminal are not applicable to multiterminal transmission lines. So far some techniques have been presented to solve fault location problem for multi-terminal transmission lines. In these methods, lumped or distributed frequency domain models of transmission lines have been used. In multi terminal lines, faulty section shoul...
We investigate leading twist transverse momentum dependent origins of transverse spin asymmetries in hadron-hadron collisions. The chiral-odd T-odd distribution function with intrinsic transverse momentum dependence, which would signal an intrinsic handedness of quarks inside a hadron, could account for single spin asymmetries and at the same time for the large cos 2φ asymmetry in the unpolariz...
In this paper, an improved impedance based method has been proposed for fault location in power distribution network with presence of photovoltaic distributed generation resources. Within this method, current and voltage are measured at the beginning of feeder and at the location of distributed generation resources. The π line model is used for improving the accuracy of the suggested method....
different methods for detecting broken bars in induction motors can be found in literature. many of these methods are based on evaluating special frequency magnitudes in machine signals spectrums. current, power, flux, etc are among these signals. frequencies related to broken rotor fault depend on slip. in industrial environment due to some phenomena - such as load oscillation, other faults an...
With advances in computer networks, special attention has been paid to Wireless Sensor Networks (WSN). Because of their wireless nature, the probability of the fault occurrence in such networks is high. There has been a lot of research conducted on the field of fault detection in WSN. Among the fault detection methods, the disturbed ones are more important because they outperform other methods ...
Accurate locating of fault in power distribution system (PDS) can significantly improve the reliability indices. In this paper, a new simple and practical method is proposed for estimating the section and distance of fault in PDS. In the proposed method, at first the protective devises are allocated and then specially set in such a way that they are coordinated and the unique current pattern is...
Characteristics of ground motions close to the earthquake source can be considerably different from those of far-field motions which should be considered in design process of structures. The current study aimed to present new design response spectra for Iranian seismic design code taking into account the near-fault effects. For this purpose, a new attenuation relation based on the ground motion...
In this paper we investigate the effect of a random transverse field, distributed according to a trimodal distribution, on the phase diagram and magnetic properties of a two-dimensional lattice (square with z=4), ferromagnetic Ising system consisting of magnetic atoms with spin-1. This study is done using the effectivefield theory (EFT) with correlations method. The equations are derived using...
The mathematical model of a piezoelectric transformer the transverse-transverse type and describes method its construction has been presented. Although modeling programs for devices can achieve any predetermined accuracy, simulation results cannot be directly used in development electronic equipment, because are not integrated with CADs, this reason most often calculations circuits based on pie...
