“…They have successfully been applied in engineering electromagnetics [35][36][37][38], in mechanical engineering [39,40], and been coupled with turbulent flows in earlier papers, notably in metallurgy and manufacturing processes [41][42][43]. A GA works with a population of candidate solutions which are called individuals.…”

Abstract-This paper is devoted to a laser-based diagnostic technique described as a method for solving an applied inverse problem in turbulent media using laser beam propagation. This problem consists of extracting local information about temperature fluctuations inside a hot turbulent jet of air, from the luminous photodiode trace produced by a laser beam, after having traversed the jet. A genetic algorithm is implemented in order to calculate the optimized laser beam directions corresponding to the whole luminous trace. An approximated ray equation which is proved from the geometrical optics is solved numerically by using those directions and enables to determine the variance of temperature fluctuations along the whole path of the laser beam. A good agreement coming from the comparison between the results obtained and the published experimental data proves the validity of the method.

“…Conformal antenna arrays are becoming increasingly important in the designs of future radar and communication systems [1][2][3][4][5][6][7][8]. This is because they can provide benefits such as visual unobtrusiveness, noninterference between aerodynamic performance and the performance of antenna.…”

Abstract-A method of designing a cylindrical conformal array with shaped-beam and reconfigurable dual-beam using a modified particle swarm optimization algorithm is proposed in this paper. The proposed algorithm is easy to implement and efficient to be used in synthesizing conformal arrays with digital attenuators and digital phase shifters. Moreover, the proposed synthesis has taken the actual active element patterns into account, which can reduce the error between computation and realization. Good agreement can be obtained between the desired patterns and the synthesized patterns.

“…GA has advantages in solving constrained nonlinear optimization problem with parallelism, global search and self-adaptation [11]. So GA is becoming a valuable tool for the analysis of signals in many applications [12][13][14][15][16][17][18][19][20][21]. Traditional simple genetic algorithm (SGA) trends to trap in local optimization as a result of the elitist strategy and the selection strategy based on proportion.…”

Abstract-Aluminum conductor steel-reinforced (ACSR) cable is a specific type of stranded cable typically used for electrical power delivery. Steel strands in ACSR cable play a supportive role for overhead power line. Inspection timely is an important means to insure safety operation of power lines. As steel strands are wrapped in the center of ACSR cable, the common artificial inspection methods with optical instruments are limited to find inner flaws of power line. Recently, inspection of power line by robot with detectors is a method with good prospect. In this paper, the optimal design model of detector based on magnetic leakage flux (MLF) carried by robot for detecting broken steel strands in ACSR cables has been proposed. The optimal design model of MFL sensor is solved by niche genetic algorithm (NGA). Field experiment results show that the design method of the detector can be applied to different types of ACSR cables. The magnitude field induced by transmission current has nearly no influences on the detection of broken steel strands, and the developed detector carried by robot can identify broken steel strands with high reliability and sensitivity.
