Application of renewable energy sources have shown perfect potential as a form of contribution to conventional power generation systems. This paper presents an hybrid system based on photovoltaic (PV) module and PEM (proton exchange membrane) fuel cell (FC) with the aim of selling electricity to distribution network (DN) and improve its reliability. In this paper […]
With respect to the increasing growth in the subscribers of wireless cellular networks and the necessity of providing network services with reasonable quality in any location, the importance of enhancement in the wireless network services is deeply felt. This means that network users expect to receive voice, data, and multimedia services with reasonable QoS, regardless […]
In this paper an approach is presented for edge detection of noisy images that have been degraded by impulsive noise. It uses Fuzzy Inference System (FIS) and Ant Colony Optimization (ACO). Starting with, using the FIS with 12 simple rules is to identify the noisy pixels in order to perform the filtering operation only for […]
The demand for RFID tags has recently increased due to the development of the RFID. Over the past decade, great efforts have been devoted to the design of RFID tags without chip inside. The concept of chipless RFID tags appears to be a promising solution for low cost item tagging because the cost of active […]
Induction motors are widely used in industrial, commercial and residential applications. An induction motor may exposed to the unbalanced voltage in the various operating conditions. Therefore, it is vital to investigate influences of voltage unbalance on performance of induction motors. In this paper, the performance of a three-phase squirrel cage induction motor has been simulated […]
With an increase of available datasets in web of data, ranking the datasets will be of prime importance. In this article, the famous PageRank algorithm is extended and a new link-based method is proposed for ranking the datasets in web of data. In this method, the number of links to the dataset, the type of […]
A fully integrated low-noise amplifier (LNA) with 0.4V supply voltage and ultra-low power consumption at 1.5GHz by folded cascode structure is presented. The proposed LNA is designed in a TSMC 0.18 µm CMOS technology, in which the all transistors are biased in sub-threshold region. Through the use of the proposed circuit for the gain enhancement […]
In this paper, reliability of power system has been studied based on different Static Var Compensator (SVC) locations in power system. First, reliability model of SVC has been presented and then reliability indices of power system have been introduced. Furthermore, three different scenarios have been considered for SVC placement and these scenarios have been compared […]
ABSTRACT:In present study ,we intend to investigate the evolution of supercontinuum generation (SCG) through triangular photonic crystal fiber (PCF) at 1310nm by using both full-vector multipole method (M.P.M) and novel concrete algorithms: symmetric split-step fourier (SSF) and fourth order runge kutta (RK4) which is an accurate method to solve the general nonlinear schrodinger equation (GNLSE). […]
The switched reluctance motor is a singly excited, doubly salient machine which can be used in the generation mode by selecting the proper firing angles of the phases. Due to its robustness, it has the potential and the ability to become one of the generators to be used in the harsh environment. This paper briefly […]
