This paper illustrates a multi-wing hyperchaotic attractors in coupled Lorenz systems. Novel four-wing hyperchaotic attractors are generated by coupling two identical Lorenz systems. Based on the Lyapunov stability theorem, this paper shows the synchronization between two identical hyperchaotic systems, the sufficient conditions for achieving the synchronization are derived. In addition, this synchronization...
Based on Lyapunov stabilization theorem, considering the diffusionless chaotic system, a method is proposed for global chaos synchronization of three identical systems. Meanwhile, the method of three different structures chaotic systems global synchronization is shown. Then this method is applied to secure communication through chaotic masking, use three coupled identical systems, propose a novel...
The mainly traditional File Systems are constructed on single device where the metadata and data access interfere with each other which will lead to performance degradations. In this paper we propose a volume based mechanism in BWFS to separate metadata from data into different devices by isolations both in store location and IO path. Test result has verified the effectiveness of metadata isolation...
The analysis of the vast storehouse of email content accumulated or produced by individual users has received relatively little attention other than for specific tasks such as relationship. Current email analysis in standard client applications consists of keyword based matching techniques for relationship of email files. We have implemented a tool, called the email mining set (EMS) for analyzing...
In the paper, a kind of expanding model of rough set, which is with membership grade degree and contribution was presented after lucubrating the deficiencies of the theory of traditional rough set. In this model, the information system with membership grade and contribution, the processing of noises, similar space partition, the dependency grade calculation of decision attribute on condition one,...
