several approaches are available to reduce pulsating torque components in permanent magnet motors. one of the known techniques is stator tooth shape modifications. this paper presents an integrated algorithm applicable for tooth shape optimization of permanent magnet motors. this method focuses on the reduced basis technique, finite element analysis and taguchi method and is conducted on tooth ...

in recent years, soft computing methods have generated a large research interest. the synthesis of the fuzzy logic and the evolutionary algorithms is one of these methods. a particular evolutionary algorithm (ea) is differential evolution (de). as for any ea, de algorithm also requires parameters tuning to achieve desirable performance. in this paper tuning the perturbation factor vector of de ...

Minimum Total Harmonic Distortion (THD) is one of the most important requirements from multilevel inverter concerning good Power Quality. This paper presents the optimization of THD in 13 level Cascaded Multilevel Inverter with unequal dc source using Genetic Algorithm (GA). THD minimization is taken as an optimization problem derived from Selective Harmonic Elimination Pulse width Modulation (...

An effective 2-phase method for removing impulse noise was recently proposed. Its phase 1 identifies noisy pixel candidates by using median-type filters. Then in phase 2, it restores only the noisy pixel candidates by some variational methods. The resulting method can handle salt-and-pepper noise and random-valued impulse noise of noise level as high as 90% and 60% respectively. The aim of this...

1. Abstract Single-level parallel optimization approaches, those in which either the simulation code executes in parallel or the optimization algorithm invokes multiple simultaneous single-processor analyses, have been investigated previously and have been shown to be effective in reducing the time required to compute optimal solutions. However, these approaches have clear performance limitatio...
