Abstract:In order to improve diagnosis precision and decreasing misinformation diagnosis, according to the intelligence complementary strategy, a new complex intelligent fault diagnosis method based on rough sets theory and RBF neural network is presented. Firstly, basis on data pretreatment, the fault diagnosis decision table is formed, and continuous datum are discretized by using hybrid clustering method. Rough sets theory as a new mat hematical tool is used to deal with inexact and uncertain knowledge for pattern recognition. The target is mainly to remove redundant information and seek for reduced decision tables which to obtain the minimum fault feature subset. The neural networks adopted were of the feed-forward variety with one hidden layer. They were trained using back-propagation. The method can reduce the false alarm rate and missing alarm rate of the fault diagnosis system effectively, and can detect the composed faults while keep good robustness. | |||

Abstract:With the extended variable-coefficient balancing-act method and symbolic computation, a new auto-Backlund transformation to the variable-coefficient Huxley equation which describes the nerve propagation in biology is derived. In virtue of the auto-Backlund transformation, two families of analytic solutions and soliton-like solutions of the variable-coefficient Huxley equation are obtained. Since the famous Huxley equation is a special case of the variable-coefficient Huxley equation, a new shock wave solution of the Huxley equation is obtained with the same method. | |||
