We analyze the asymptotic variance of distributed consensus algorithms over large-scale switching random networks. Our analysis is focused on consensus algorithms over large, i.i.d., and directed Erdo??s-Re??nyi random graphs. We assume that every agent can communicate with any other agent with some fixed probability c/n, where c is the expected number of neighbors of each agent and n is the size...
In the last few years, several Web-based conference management systems have been developed and used by many international conferences. However, almost all of them were built on stand-alone Web servers. Their fault tolerance, scalability and ability of responding to dispersed users are limited. Aimed at addressing these problems, this paper presents a novel approach for Web-based conference management...
Due to the difference between Web page and plain text document, the concept of Web object is introduced in this paper. Besides, the supposed state transition and the emission symbol conditions are improved based on Pseudo two dimension hidden Markov model (P2D-HMM), and a novel web objects information extraction method is proposed. Finally, through an example, it shows that the proposed method has...
Human-computer interaction (HCI) in embedded system is an issue concerned by many people. From the engineering point of view, by analyzing the scenario of embedded system, we propose the use of multi-list for HCI in embedded system. We have set up the model and implemented the system. Our engineering practice shows the effectiveness of this scheme.
Let Rn be a n-dimension Euclidean space (n ges 2), D sub Rn is a proper sub-domain of Rn, for x, y isinD, 0 < c < 1, kD(x, y) > log(1/(1-c)). There is a quasi-conformal homomorphism F:Rn rarr Rn with the following properties: (1) kD (x,F(y)) les log(1/(1-c)); (2) F:Rn\D rarr Rn\D is the identity; (3) log kD(F) les (1/c)kD(x, y).
The purpose of this paper is to answer a basic problem of finite element method that is how do the elements which have determined shapes form the element grid which has determined structure. In order to study this problem, a method called chain-making and chain-coupling is established. Through this method the qualified relationships between the geometric structures of the element grid and the geometric...
