In this paper, the problems of control and synchronization of a new hyperchaotic Lorenz system with uncertain parameters are studied. Based on the Lyapunov stability theory and the adaptive control theory, this new uncertain hyperchaotic Lorenz system is suppressed to its unstable equilibrium. Furthermore, synchronization between two identical uncertain(More)
In modern business, vast amounts of data are accumulated, which makes the decision-making process complicated. How to change the existing situation of "mass data, poor knowledge", support better business decision-making and help enterprises increase profits and market share become the business and IT sector issues of mutual concern. Business intelligence(More)
In modern retail business, increasing standards, automation, and technologies have led to vast amounts of data becoming available, however, business decision-making process has become complicated. Traditional database system has been unable to meet userspsila demand in mass data intelligent analysis & forecast. How to change the existing situation of(More)
In many real-world topic detection tasks, the process of the topic detection is often interactive, which means the users are likely to interfere the reason process by expressing their preferences. We proposed an algorithm, iOLDA, and the software framework for interactive topic evolution pattern detection based on Latent Dirichlet Allocation (LDA). To abate(More)
— Ensuring high quality of service (QoS) of multicast video stream over a next generation network is a challenging issue, and how to implement the wire-speed multicast with hardware logical support in the network nodes of every hierarchy is a key solution to achieve high QoS multicast. Currently, the multicast packets are processed in this way, in which(More)
Studies confirming a possible relationship of polymyositis within thyroid dysfunction, either hypothyroidism or hyperthyroidism, are hardly available. To define the association, identify clinical, laboratory, electromyographic, and pathologic features in polymyositis (PM) patients with hypothyroidism or hyperthyroidism, we conducted a MEDLINE and Chinese(More)
The microbial transformation of a series of tetrahydroprotoberberines (THPBs, 1–5) by Gliocladium deliquescens NRRL1086 was investigated. In this research, the novel glycosylation of tetrahydroberberrubine (1) was observed with fast rate and high regio- and enantio-selectivity. One pair of unique enantiomorphic alkaloidal glycosides T-1 and T-2 was isolated(More)
