Emotion identification analysis became popular research area nowadays. It can be used in many areas such as physiology, education, murder squad, tendency to crime to get a clue about mental signals of a person. Facial expressions are kind of communication channels that carry sense signals. Therefore, they are as important as speech and body movement. Sometimes they are much more meaningful because...
We develop a new algorithm to segment the hippocampus from MR images. Our method uses a new classifier ensemble algorithm to correct segmentation errors produced by a multi-atlas based segmentation method. Our classifier ensemble algorithm searches for the maximum likelihood solution via gradient ascent optimization. Compared to the additive regression based algorithm, LogitBoost, our algorithm avoids...
In this paper, the control of Voltage source converter which consists of six IGBT power switches is realized. Grid connection of VSC is provided through LCL filter and sinusoidal pulse width modulation (SPWM) technique which has 9 kHz switching frequency, is used for switching. Three different way of control including a - b - c, d - q and input - output linearization nonlinear control, are analyzed...
In this paper, simulations of three - phase voltage source rectifier using L and LCL filter under input - output linearization nonlinear control, are realized. The control algorithm requires transformations between a-b-c and d-q frames. A bridge rectifier having six IGBT power switches has been employed. For switching, compared triangular wave sinusoidal pulse width modulation (SPWM) technique has...
