In Alopex-DE, each original individual has its......
Electrocatalytic properties of Ni-S-Co coating electrode for hydrogen evolution in alkaline medium YUAN Tie-chui(袁铁锤), LI Rui-di(李瑞迪), ZHOU Ke-chao(周科朝) State Key Laboratory of Powder Metallurgy... that the coating has amorphous structure and the particles of the surface are fine with large specific surface area. The Ni-S-Co alloy is more active with lower potential for hydrogen evolution, higher......
. An approximate method for finding segments with minimum aggregate distance is proposed which can improve the response time. In order to index large volumes of trajectories, scalable and efficient trajectory... of search time among load time, ANN and computing convex and centroid, is related to ANN.Key words:Approximate aggregate k nearest neighbor (AAkNN); scalable and efficient trajectory index (SETI......
as the effects of wind, wave and current disturbances, designing a high performance ship course controller is always a very complex issue. The ship trajectory tracking control was investigated. The ship trajectory tracking control was designed by the adaptive fuzzy control method. Eventually, the simulation studies for a replica were carried out by utilizing Matlab toolbox. The simulation results......

The mathematical models of the robot, including kinematic model, dynamic model and spline trajectory planing, are established and verified. Since it is difficult to describe the real-time......
Nonclassical constitutive model involving void evolution of casting magnesium alloy CHEN Bin(陈斌), PENG Xiang-he(彭向和), FAN Jing-hong(范镜泓), SUN Shi-tao(孙士涛) College of Resource and Environment...> Abstract: The void evolution equation and the elastoplastic constitutive model of casting magnesium alloy were investigated. The void evolution equation consists of the void growth and the void......
with the trajectory of unmanned aerial vehicle (UAV) in the capturing phase, and changed with the ideal landing area in the tracking phase. The UAV’s speed and position errors were calculated in the new coordinate system, the errors were corrected through the trajectory controller, and UAV accurate guidance was realized. An active service carrier UAV was regarded as the research object......
