, XIAO Hong-feng (School of Information Science and Engineering, Central South University, Changsha 410083, China) Abstract: The hand path tracking and joint trajectory planning is a very important...-time and accurate hand path tracking and joint trajectory planning method for industrial robots was proposed. Through selecting some extra knots on the specified hand path by a certain rule, which......

theory, a mathematical modeling method involving driver’s capacity of fuzzy perception and decision-making in the models of speed controlling and trajectory tracking was established, and based on gray...-making behavior. Finally, through field experiments, the modeling methods were verified to be reasonable and feasible. Key words: curves of two-lane highway; speed decision-making model; trajectory......
the observed microstructure change. Key words: hydrogen evolution reaction; overpotential; Ni-Mo alloy electrode 1 Introduction Many transition metal alloys with binary and ternary compositions have been studied as hydrogen evolution reaction electrodes in water electrolysis[1-6]. The activity of such metal alloys for the hydrogen evolution reaction depends on at least two factors, i.e.......

; 文献标志码:A 文章编号:1672-7207(2012)01-0184-05 An improved hybrid differential evolution algorithm used for multi-objective optimization... differential evolution algorithm for multi-objective optimization problems was proposed. To increase the convergence speed, differential evolution and particle swarm optimization were combined, and then multi......
in simulated marine tidal zone including drying environment and wetting environment. Then the inner relative humidity (RH) evolution of concrete under above-mentioned environments was systematically investigated. The results show that the inner RH evolution of concrete includes vapor phase saturation stage and relative humidity decrease stage. The RH of concrete keeps steady firstly......
on interval temporal syntactic model was proposed to recognize human activities in video flow. The method is composed of two parts: feature extract and activities recognition. Trajectory shape descriptor...: trajectory shape descriptor; speeded up robust features (SURF); histograms of optical flow (HOF); PLSA probabilistic latent semantic analysis; syntactic model 1 Introduction Human activities......
