A terminal sliding mode control based on extended fuzzy disturbance observer
Publication Year: 2010,Page(s):1 - 4
In this paper, a terminal sliding mode control based on fuzzy disturbance observer scheme is proposed. For a nonlinear system, the disturbance that can not be directly measured is estimated using a fuzzy disturbance observer. Considering both the terminal sliding mode surface and the observer error, a novel adaptive law for the fuzzy disturbance observer is presented. Based on the output of the fu...Show More
The distance measure for features is of critical importance for all kind of classification methods in image retrieval algorithm.

Using revised string edit distance to sign language video retrieval
Publication Year: 2010,Page(s):45 - 49
Cited by: Papers (2)
In this paper, we present a revised method to compute the similarity of traditional string edit distance. Given two strings X and Y over a finite alphabet, an edit distance between X and Y can be defined as the minimum weight of transforming X into Y through a sequence of weighted edit operations. Because this method lacks some types of normalization, it would bring some computation errors when th...Show More

We present and analyze a model of Opinion Dynamics and Bounded Confidence on the stochastic movement world. There are two mechanisms for interaction. `Eyeshot' limits the set of neighbors around the agent and `Bounded Confidence' chooses the agents to exchange the opinion in the set. Every time step, agent i looks for the agents in its eyeshot and adjusts their opinion based on the algorithm of Bo...Show More
