This paper introduces an intelligent evaluation method based on improved PSO-WNN (partiele swarm optimization-wavelet neural network) for speech denoising in high background noise. Firstly, by using Lyapunov stability theory, convergence conditions of a single particle is discussed and based on the result, a new strategy is introduced to improve the(More)
Reconfigurable software systems are usually responsible for realizing many kinds of client requests. As the complexity of such systems architecture, using mathematical analysis is difficult to directly analyze its availability. Therefore, this paper describes a simulation method to analysis the availability of reconfigurable software systems. Firstly, based(More)
