    Abstract: This paper is mainly doing simulation using Matlab to filter harmonics which are found in a Permanent Magnet Synchronous Generator (PMSG) Wind Energy Conversion System (WECS) connected to a three-phase load through a full converter (AC/DC/AC). Harmonics are caused by the converter system. To reduce these harmonics, an effective filter is needed. Th... Show More

    Abstract: When the data packets transferred in duplex directions from part A to part B, and the data arrives at B, instead to sending a control frame from B to A, receiver B waits until the network layer at B send the next packet to A, and the Acknowledgment is attached in data frame from B to A using the field of Acknowledgment in the data frame header. so ...

    Abstract: At this stage of development of intercity passenger transportion, there is a need to take into account fluctuations in demand for the services of carriers, which takes place over time. These fluctuations in demand are mostly tied to the onset of a period of nationwide or religious celebrations, the onset of a period of mass holidays, sports and cul... Show More

    Abstract: Loss function is one of the most topics in Bayesian analysis. The aim of this paper is to study the estimation of the shape parameter of Laplace distribution using Bayesian technique under a new loss function, which is a compound function of LINEX function. The Bayes estimator of the parameter is derived under the prior distribution of the paramete... Show More
