The constraints of genetic spectrum assignment model without co-channel interference in cognitive radio networks are analyzed in this paper. An improved genetic spectrum assignment model is proposed, the population of genetic algorithm is composed of sets of feasible assignment and infeasible assignment. The penalty function is added to the fitness function, and the fitness of chromosomes that dissatisfied...
Plastic profiles produced by extrusion die are cooled down and calibrated by calibrators, so it is very important to properly design the cooling system in calibrator for the profile quality. In this paper, considering the cooling channels' location, size, number and the calibrator's material distribution simultaneously, the optimization design of heterogeneous calibrator cooling system is investigated...
Analysis for existed pavement cracks extraction algorithm, pointing out the problems and deficiencies, a phase-grouping pavement cracks extraction method based on genetic algorithm was proposed. This method first used a genetic algorithm to determine the optimal threshold, which achieved the threshold of image segmentation; then adopted phase-grouping method to extract pavement cracks information...
