Voltage and Power Quality Control in Wind Power Application by Dynamic Compensation
Abstract: Power quality problem is a critical problem in a power system. Most of the pollution problems created in power system is due to the nonlinear nature of loads. Due to large amount of non-linear equipment, impact and fluctuating loads (such as locomotive, arc-furnace, welding equipment, etc.); wind power as a rule, does not contribute to voltage regulation in grids. Also wind power very often is a source of voltage sag …

Discrete Hidden Markov Model based Face Recognition System Introducing Sustainability of Uneven Lighting Distortion
Abstract: The aim of this work is to enhance the performance of appearance based face recognition system to remove the uneven lighting effect which is generally occurred in natural environment. Active Shape Model has been used to detect the facial shape and contrast based edge detection technique has been applied to reduce the uneven lighting problem. Linear Discriminant Analysis has been used to reduce the dimension of the facial feature vector. …
