Abstract: Information push systems play an important role in reducing information overload for people visiting online sites, but their services could be improved by using data from online social networks, electronic communication tools and others. Information push systems are used by electronic commerce sites to suggest products to their customers and to provide consumers with information to help them determine which products to buy. There are many electronic commerce applications on the Web. A common shortcoming is the lack of customer service and marketing analysis tools in most electronic commerce websites. The paper presents the information push system using case-based reasoning. It introduces the case-based reasoning technology and analyzes the case representation, case library and case search. Lastly, it gives the architecture of the information push system using case-based reasoning.

Abstract: Since the wireless mesh network topology dynamics and the radio channels instable, the design of wireless mesh network routing protocol become one of the key factors to determine the performance. This paper mainly studied the existing several kinds of typical three-layer mesh network routing protocol (DSDV and AODV), aimed at the defects of three-layer routing limited to the network topology changes, the paper proposed a network model based on two-layer routing. Forwarding the packet, establishing and maintaining the communication links are accomplished on the Mac layer. Simulation tests showed that two-layer routing has a big improvement on the efficiency of packet forwarding, and it effectively reduced the routing overhead and end-to-end delay simultaneously.

Abstract: In recent years,the ad hoc network has been paid extensive attention due to its characteristics of non-center and self-organization.Firstly this paper introduces three typical routing protocols AODV,DSDV,DSR,and the principles of them; then,adopts the NS2 simulation platform to simulate the performance of end-to-end delay,routing overhead and packet delivery ratio by changing the number of nodes and the paused time of nodes.Finally,by comparing the simulating results, the comparison conclusion is provided.

Abstract: In recent years, with the rapid development of computers, computer-aided-translation software has been used more often, which can improve the efficiency and quality of translation. This paper analyzes the characteristics of the four commonly used computer-aided-translation software at home and abroad--SDL Trados, Déjà Vu, Wordfast and Yaxin in satisfying different users’ needs, points out their characteristics and provides reference for those who are interested in computer-aided-translation technology.

Abstract: The Alfresco development tool, which includes Apache Tomcat, MySQL and WebService, is an open platform for building a functional database system in a Java website. In order to improve the enterprises’ management efficiency in specialized industrial townships, a micro-information system based on Alfresco development tool has been proposed. In the construction of the micro-information system, Alfresco database exhibits great superiority in network database architecture, data query with Lucene search engine, data management and data security. In this paper, the general design ideas, functions, key technologies and realization methods of the Alfresco database are introduced.

Abstract: Aiming at the deficiencies of traditional RBAC model, on the basis of studying of the models introduced in the literatures published, this paper puts forwards an improved model--MR-RBAC, including its concepts and design. This model is implemented by adding restriction strategy on the operation objects and data objects, assignment different privileges to different users via configuration mapping of functions and menus. The implementation and practice indicates that the MR-RBAC model not only simplifies privilege management, but also improves the system security and privileges management flexibility.

Abstract: With constantly expansion of companies, more and more woks on communication become the managers’ top issue. It is urgent to use computer technology to improve work efficiency and achieve of information sharing as much as possible. The managers need a platform to keep their information updated real-time, statistics tasks information at any necessary times, and the staff also need platform to record the task process, make schedule to alarm. Therefore, ASP.NET-based task management information system is designed and implemented. The system is developed with Visual Studio 2005 and SQL Server 2005, including task management module, file management module, schedule management module and background management module. With running in practical, it is proved that the system improved working efficiency greatly and implemented work information sharing effectively..

Abstract: with the rapid development of body area network technology and the internet of things technology, makes the effective combination of these two techniques. Scientific connection method of study of this two kinds of techniques in this paper, to solve the core problems of these two kinds of technology association, and proposed solutions. The combination of these two techniques, and provide the technical support is widely used for applications of the Internet of things technology development and body area network.

Abstract: In the reliability evaluation studies of the component-based Web system, the stated-based models and the path-based models suffer from the high time-consumption for the high complex web structures. In this paper, a SVM Reliability Evaluation Framework for the component-based Web system (SVMREF) with a low computational complexity is presented. SVMREF employs the Web component reliabilities as the SVM inputs and outputs the final reliability evaluation after the well-trained learning process. Our proposal has a low evaluation complexity and outperforms the state-based model and the path-based model. The experiment results and the analyses show that SVMREF has a better reliability evaluating convergence and SVMREM is evidently lower than the contrast models when the Web system structure is complex .

Abstract: . As the development of modern information technology, the digitization, mobilization and networking of working environment have become the general trend, directly from which the virtual editing environment cooperatively supported by the computer comes. The realization of mobile officing and home officing through VIEW makes the editing of news agencies virtual and links news gathering and editing with network to fully enhance the efficiency of news publishing and provide better working environment for editors and reporters.
