The key technique of image-retrieve which is based on semantic quest and talkback mechanism which is significant symbol from junior to senior is a retrieve technique based on image-content. Therefore, the research of this program...
Discussed the basic principles of terminal equipment of Linux pseudo, as well as the naming process and a typical structure of pseudo-terminal. Analyzed how access to and use of pseudo-terminals pseudo-terminal master and slave data communications equipment dynamically. Combination of layer two tunneling protocol (L2TP) to achieve the Linux process, it gives the flexibility to increase end-user VPN,...
Peer-to-Peer (P2P) has attracted a great deal of interest in industry and research literature. Peer-to-peer information systems (P2PIS) are Internet-based systems for distributed data management that operate in a completely decentralized manner, aiming at unlimited scalability with millions of nodes, continuous availability regardless of node and network failures, self-stabilization in the presence...
To improve the efficiency of auction-based negotiation system in e-marketplace, this paper presents a model of game agent for auction-based negotiation, a bid negotiation algorithm based on game theory and a framework of game-based electronic marketplace. It provides a new effective way to establish buyer game agents for making buyer agent bid more rationally and a game negotiation agent system for...
A Web-based GIS provides simplicity and interactivity such that some simplified functions of the watershed management can be open in Internet/Intranet for specific users or general public users. A palm-size GPS device provides location information, x and y coordinates, in the observation site that can bring all associate data of physical, chemical, and biological conditions. This paper presents an...
The DoS attack is the most popular attack in the network security with the development of network and internet. In this paper, the DoS attack principle is discussed and some DoS attack methods are deeply analyzed. The DoS attack detection technologies which include network traffic detection and packet content detection are presented. The DDoS based on DoS is introduced and some DDoS tools are described...
Service composition is a technique to recompose various heterogeneous network services for a new business. A modern streaming media system may run multiple businesses. Their resources can easily be improperly distributed and under utilized. This paper studies service composition in the context of streaming media applications. A three-layer model is adopted to describe the system. The optimal service...
The paper first outlined the Java3D technology in three-dimensional model of interactive design applications. Proposed the use of Java3D virtual three-dimensional model for the description of the client to read through the remote server customers to upload three-dimensional graphics data, user interaction with the virtual three-dimensional interactive modeling program, using the procedure of drawing...
By analyzing the evaluation method and working characteristics of the design courses in universities, a fuzzy comprehensive evaluation method is advanced, which based on fuzzy clustering analysis. According to the fuzzy membership degree theory, the author translated the qualitative evaluation into quantitative evaluation. Through this, the problem that the qualitative and quantitative evaluation...
Software evolution techniques have been traditionally concentrated on the code level. However, recent researches have shifted the focus of evolution from the code level to the architectural level. In this paper, we proposed a formal modeling method of dynamic evolution of web-based systems at the architectural level using hypergraph grammars. We represent architectures of web-based systems with hypergraphes,...

At the end of this article, this paper gives some practical advices...
In distributed virtual environment (DVE) systems, a distributed server infrastructure is often used to reduce the latency between servers and clients. Under this infrastructure, mapping clients to proper servers is one of the key issues for improving the interactivity and overall performance. Most traditional methods of mapping the clients to servers only consider the load balancing problem. However,...
In materials science, effective tools are needed to organize and systematically analyze vast amounts of highly diverse materials data stored in heterogeneous databases. We have developed and deployed a data warehouse named materials data warehouse (MDW) as a tool to apply integrative approaches to the analysis of large materials data. Integration of a data warehouse enables the proper materials data...
