In this paper, a class of switched neutral systems composed of a finite number of nonlinear neutral systems is discussed. Under the condition of all the subsystems being stability, stability conditions for nonlinear switched neutral systems are established in terms of multiple Lyapunov functionals and functions, respectively. The stability conditions in terms of multiple functions are obtained by using Razumikhin techniques.

A speed control approach with grey control theory is proposed based on the state-space model of the star-connected three-phase brushless DC motor in line-voltage mode. The algorithm of the grey predictor is given. Double-loop PI controllers and the GM (1, 2) are used to compensate the disturbance from the load and internal parameters of the motor, while the uncertainty part is considered as a grey system. To assure the system responds to the newest behavior in time, the initial discrete state sequence in GM (1, 2) model is established by the equal dimension and new information method. The simulation results have shown that the GM (1, 2) predictor can reduce the disturbance in the speed and current loops, and proved the effectiveness and good anti-disturbance ability of the proposed control method.

Distributed anomalous traffic is difficult to detect, since it is simultaneously dispersed in many links and tend to not present any obvious anomalous features in a single link. This paper proposed a multi-scale spatial detection method against distributed stealthy traffic anomaly, it can deploy early-stage detection on key nodes of network. Multi-scale wavelet packet analysis is performed separately on links at which information is available on each node, with the aim of getting abnormal frequency ranges at different time sections and reconstructing signals with anomalous features. Then from a spatial point of view, evaluate deviation degree of high dimension vectors that composed of reconstructions by kernel density estimation as anomaly indicator. Detection results on both real anomalies of American education backbone network and synthetic distributed anomalies shows, our method performs better than existing method.

Stream scheduling strategy used in streaming media server can improve largely system service capability by increasing system efficiency and reducing bandwidth requirement. In this study, an incorporated scheduling strategy, which combines period-patching and batching scheduling strategy, is proposed. It uses period-patching scheduling to transmit the group-broadcasting streams, and then incorporates the nearby patching streams in a shared patching stream. The bandwidth resource and Qos of system can be improved at the expense of a little longer average waiting time. The simulation results show that incorporated scheduling strategy is more efficient and economical, in aspect of patching stream number and bandwidth requirement, than the typical period- patching scheduling under the circumstances of high visiting frequency for media resources or bursts of rapidly occurring events of user requests.

This paper constructs a Wavelet Neural Network (WNN) for image edge detection based on the fact that image edge detection is essentially a classification problem and WNN has powerful classification and identification capacity. The innovations of this paper include utilizing information of differential and filter operators in constructing the network and integrating the advantages of Canny and LOG operators in the selection of network training samples. Experimental results indicate that the method proposed in this paper can extract the image edge information effectively and the network presents good generalization ability. Also, a new edge detection based on wavelet transform of modulus maxima threshold is also proposed in this paper during the research on WNN. Finally, the selection of threshold, wavelet function and other parameters is discussed of WNN.
