In this paper, the Optimal Minimization of the Total Harmonic Distortion (OMTHD) technique is improved to calculate minimum phase THD and approximate line to line THD versus variable Modulation Indices (M). In Developed single-phase OMTHD technique, the Fitness function is proposed to minimize phase THD, and fundamental component as a constraint is separately added to Fitness function to adjust the...
This paper presents a new tuning algorithm for a neural network which not only considers the weighting but also the size and connectivity of the network. The approach is done by two parts: the addition of the switch-based hidden nodes and the application of a modified fitness function. The new model is tested by using two simple logic functions. The results show that the modifications lead to the...
March tests have been found to be very effective for fault detection and diagnosis in memories. Effectiveness of a March test is usually decided by the number of faults that can be detected using the test. The more the number of fault models covered, the better the test. March tests with good fault coverage have been developed but the test power also plays an important role in deciding the effectiveness...
There exists an effective method for reduction of multilevel inverter's harmonics which is called the optimal minimization of the total harmonic distortion (OMTHD) technique. OMTHD technique is applied only for THD minimization with no constraint on the value of fundamental component; whereas, the primary objective in any method of inverter control is adjustment of the fundamental component to the...
In this paper, a new evolutionary algorithm (EA) to solve multi-objective constrained optimization problem (MCOP) is proposed. First, the rank of the individual and the scalar constraint violation of the individual are defined. Then, based on the rank and the scalar constraint violation of the individual, a new fitness function and a switch selection operator are presented. Accordingly, when the individuals...
An automated synthesis procedure, based on genetic algorithms, to design optimum performance Si-integrated radio-frequency and microwave binary-weighted single-ended switched capacitor arrays (RFSSCAs), is presented in this paper. The method determines the RFSSCA circuit size and the circuit components values from the top-level system specifications. The genetic synthesis tool optimizes a fitness...
Considers the wireless access switch (WASW) planning problem of wireless/mobile ATM networks and suggests a genetic algorithm for solving it. We first introduce our genetic optimization process. We also develop analytical models to determine the tracking and locating costs for mobile switches. The fitness function is formed by these analytical models. Load balancing and the call-to-mobility ratio...
