Genetic algorithm was used to identify the damage of frame structure. Stiffness coefficient damage factor is selected as design variable, and the weighted array difference value between inherent frequency and vibration mode of structure calculated and measured. According to the difficulty in selecting crossover rate and mutational rate for fundamental algorithm, the process of selection operator, crossover operator and mutation operator was improved. All operators were operated on parent individual. Crossover rate and mutational rate were set for 100%. Punishment function was applied for keeping the difference among individuals. The improved genetic algorithm can conserve the better individual in parent and keep off fall into local optimum. Through a 3-story frame with single variable damage and multiple variables damage study, the results showed that the improved genetic algorithm can identify the damage location and degree. © 2016 SERSC.

Logistics requirement prediction is very important to make a logistics plan. In this study, a hybrid model of particle swarm optimization algorithm and RBF neural network is proposed to predict logistics requirement. As the selection of the centers and the widths of hidden nodes and output weight of the RBF neural network model has a great influence on its prediction performance, particle swarm optimization algorithm is applied to choose these parameters of RBF neural network. Then, we perform experimental study for logistics requirement prediction by a hybrid model of particle swarm optimization algorithm and RBF neural network. The experimental results show that a hybrid model of particle swarm optimization algorithm and RBF neural network has better logistics requirement prediction ability than a hybrid model of genetic algorithm and RBF neural network, RBF neural network. Therefore, we can conclude that a hybrid model of particle swarm optimization algorithm and RBF neural network has a good application prospect in the logistics requirement prediction. © 2013 Binary Information Press.

This paper proposes a novel mechanical fault diagnosis method using a hybrid QPSO and SVM model. Mechanical fault diagnosis refers to the recognition and diagnosis of fault mechanism, fault causes, and the fault positions. Particularly, five types of mechanical faults are considered in this paper, which are 1) quality not balancing, 2) Rotor thermal bending, 3) Shaft crack, 4) Bearing fault and 5) Permanent bending. The main innovations of this paper lie in that we introduce the SVM classifier to solve the mechanical fault diagnosis problem, and then Quantum behaved particle swarm optimization is utilized to optimized the parameters of SVM. Experimental results demonstrate that, using the proposed algorithm, the accuracy of mechanical fault diagnosis is greatly enhanced than SVM and PSO-SVM model. © 2015 IEEE.

A core-shell nanocomposite particle with polystyrene sphere core and polythiophene overlayer shell was synthesized through thiophene chemical oxidative polymerization using uniquely structured polystyrene latexes template. The morphology of polythiophene shell, which has nanorods shaped or featureless surface morphology, can be simply controlled through varying the dosage and feeding methods of oxidizers. © (2013) Trans Tech Publications, Switzerland.
