Move-in-mud Robot is a kind of autonomous robots, which is used to substitute for excavating hole underwater in wreck salvage by diver according to a planned trajectory. Location of the robot is one of keys in study on Move-in-mud Robot, which is the base of move according to planned trajectory. Based on the analysis of automotive robot orientation ways, location system is designed in the paper and location principle of move-in-mud robot is analyzed. Kalman filter is used to fuse redundant depth information of the robot. The fusion arithmetic is simulated and the result of simulation showed that the fusion not only improve location precision efficiently, but also improve reliability of location.","PeriodicalId":331407,"journal":{"name":"Fifth World Congress on Intelligent Control and Automation (IEEE Cat.

As a result, the information embedded in the chaotic signal, which passes a noisy channel from the transmitter to the receiver, can be recovered in a better way when the error feedback synchronization scheme is used.","PeriodicalId":331407,"journal":{"name":"Fifth World Congress on Intelligent Control and Automation (IEEE Cat.

A quantization model based on expected compression ratio was adopted and improved. Two instances, brightness variation and insulators' flashover, were adopted and compressed. According to the results, the image data are compressed to tens or hundreds of bytes, only one piece or several pieces of SMS are needed to transmit them.

The places are defined to represent the states of the parsing process. The conditions and actions carried by the transitions are defined such that non-terminal symbols being processed can be rewritten and the derivation can be made to grow. Data structures, as the personalities of the token, are defined such that the growing derivation can be stored in the token. An application example was examined and the result shows that the Pr/T-Net model can do syntactic parsing successfully. The CFG-Pr/T-Net overcomes the limitation of pushdown automata, which only judged whether a string belonged to a given context free language, but were not able to answer the question concerning syntactic structure.","PeriodicalId":331407,"journal":{"name":"Fifth World Congress on Intelligent Control and Automation (IEEE Cat.

IETF has proposed a service model - DiffServ, which for its extensibility, has been widely accepted as a promising model. However, researchers found unfairness in DiffServ network. To solve this problem, this paper analyzed the inherent shortcomings of marker based on token bucket (TB) and time sliding window (TSW) in DiffServ, and proposed a new traffic rate estimator algorithm. This algorithm can tolerate the short-term burst of IP flows as well as reflecting the flows' temporal-behavior. Afterwards, a modified fair aggregate marking (MFAM) algorithm was presented based on the traffic rate estimator algorithm mentioned above. It contributes to fair sharing of excess bandwidth among aggregates. The author validated MFAM algorithm through simulation experimentation, and compared its performance with some other marking algorithms. The results show that MFAM algorithm has better fairness than others.","PeriodicalId":331407,"journal":{"name":"Fifth World Congress on Intelligent Control and Automation (IEEE Cat.
