Abstract: The traditional quantum evolutionary algorithm takes a long time to converge and can be easy trap into local optima. In order to overcome and accelerate the speed of the convergence, a new quantum evolutionary algorithm is proposed in the paper. The proposed new algorithm named discrete quantum bee colony algorithm incorporate the basic idea of the artificial bee colony algorithm. The initial population can be initialized randomly using quantum encoded and the population can be formed by there parts and every subpopulation can evolve cooperatively. In the end, the individual will rated according to the multi-granularity mechanism and also rated according to the evolution condition. Simulation results of knapsack problems show that the proposed algorithm performs better than other algorithm.

Abstract: The tramcar runs upward and downward frequently and the load varies with practical requirements, the operating conditions of the hydro-viscous winch are very complex, so the ordinary PID controller cannot meet the requirements of the winch. In order to control the speed of the hydro-viscous winch precisely and obtain perfect starting speed, a new fuzzy-PID control system was designed, the starting process of the winch and the speed regulation characteristics were simulated by using MATLAB. The results show that the designed control system can meet the requirements of the winch well. It can not only obtain perfect starting speed, but also adjust the running speed precisely. Research achievements of this work provide theoretical basis for optimal design and practical applications of the hydro-viscous winch.

Abstract: Cogent Automatic Fingerprint Identification System (CAFIS) was researched by Cogent Co. Ltd. This system filtrated and matched fingerprints feathers automatically by computer to search for similar fingerprints, which are identified by specialists finally. It can provide help for criminal cases. About CAFIS, this paper introduces the principle, fingerprint identification process and the system workflow. Then, it researches five functions modules; they are image acquisition, screening, feathers matching, scoring and sorting; and introduce the algorithm of feather matching briefly. Experimental results show that it has many advantages, such as the big capacity of database, quick matching speed, high accuracy, etc.

Abstract: Realize the goal quick and accurate location when the detection signal is weaker, puts forward a Fast Intelligent Tracking algorithm(FITA) with the Gain Adjustable. Wiht the goal image move in four quadrant detector, it’s size, location and output signal related to a linear probe interval. In this interval, a liner relation can be get between the spot position and the corresponding output signal. The target quick location algorithm is realized with this relation. On the other hand, the sum signal of the four quadrant detector is sampled in real-time, this sum is related to the sensor’s signal strength, then the change rate of the signal strength can be get, using adaptive learning ways to get the change trend of signal strength, and realized dynamic adjustment of the signal gain, in order to improve the signal resolution ratio when signal is weak, the tracking accuracy can be improved with this way. The experimental data show that FITA algorithm can rapidly locate position in the linear interval and accurately track through the dynamic change signal gain for the weaker signal. The track error can be improved to 1.9%.
