Abstract: Data aggregation is an important method to reduce energy consumption in wireless sensor networks (WSN). Auth-ors proposed a cluster trisecting based data aggregation scheme for wireless sensor networks in which the cluster was trisected and some reporters were assigned to each region. The nodes have same reading and located in same region with reporter will keep silent in data aggregating, thus reducing the inner-cluster transmissions. Analysis and simulation show that the transmissions of inner-cluster aggregation in our scheme lower than that of related schemes and the decrease of trans-missions is obvious when redundancy of sensor readings is high.

Abstract: This paper describes the cold rolling database system based on Web platform and the relevant technology of this system. Adopt tree-tier B/S architecture,ASP.NET technology, C# programming language. By communicating in different data storage of application , a dynamic, execute, interactive, highly efficient network application software has been built.

Abstract: In this paper, we construct a web-based document life-cycle management model. The model manages documents which consist of the institute library from their creation to the archive state. For an online office system, we aim at solving three issues: network delay, version storage problems and deletion strategy. To solve network delay, we propose both local and online document synchronized editing model. In addition, we combine the longest recursive chain with recursive chain time to optimize the system response time. In order to optimize documents to be deleted, we propose a two-step optimized method. In the performance test, the effectiveness of the method is confirmed to solve the issues of documents management.

Abstract: Wireless internet is gaining wide spread usage in teaching affairs, especially in score query system development. This paper explores how simple Math score query system can be developed for mobile devices and introduces general framework for designing such score query applications. Using the framework, based on Microsoft database software SQL Server 2000, T-SQL clause is employed to program one stored procedure for Math score query. The framework utilizes mobile phones simulator software, Nokia WAP Toolkit, which interacts with a server-side ASP (Active Server Pages) in conjunction with the associated SQL Server database. The design and implementation of the management information system are discussed in the paper, and test results are presented.

Abstract: In order to use software development environments conveniently and efficiently, this paper proposes a design scheme for integrated environment for the software development of web-based application patterns and gives instances developed under the environment. This scheme adopts browser/server architecture with Web frameset as its user interface, network intermediate components as its business process center, and uses I/O redirection to realize human-machine interaction. This paper implements the sharing of development environments, provides multi-user online use, extends computer environment, thus providing a convenient practical platform for numerous programming learners.

Abstract: With the rapid development of mobile Internet and rapid popularization of the smart phones, consumers attach increasing importance to interaction and information dissemination. In recent years, the number of users of the two-dimensional code has been dramatically increased; consumers gradually develop the habit of scan code; business models have been innovated, while the two-dimensional code as a mobile Internet portal is promoting the development of cross-media.In this paper, with analysis of cases about two-dimensional code, the reasons why the applications of two-dimensional code are popular are explored and the prospects for the development of two-dimensional code are predicted.

Abstract: Elaborate course website is one of the important contents of the elaborate course construction. In order to develop and maintain a good quality course website, we have to combine multimedia technologies with Web technologies, to make a reasonable framework for the website, to choice reasonable software tools for the development, to focus on the online teaching system, and to often maintain and update the website. With Visual Studio, Dreamweaver, Fireworks, and Flash software tools and Microsoft Access database, the paper builds up a complete website development environment, and achieves the foreground user interface and background management systems for provincial elaborate course of theoretical mechanics. The Website features have the abundant course and teaching information resources, online exams, interactive, online discussions, tutorials, and announcement. Teachers can use the convenient and efficient background systems to bring about all network resources of the elaborate course and the website update.

Abstract: With the development of the network information, information processing is vital in all aspects. Information filtering is more important research aspect. Especially Chinese information filtering is urgent affairs. According to research of the domestic and abroad, in the article vector space method and hyB+ tree index method is combined to filter text. Experimental results show that, this method is feasible.

Abstract: This paper describes the algorithms analysis and design course that uses ACM-ICPC programming competition problems as the basis for the lectures, homework and exams. Programming contest has certain timeliness, openness and objectivity of evaluation. By taking part in programming competitions students can improve solving problems and programming skills. The course of algorithm analysis and design presents the solution strategies of a number of specific issues (such as the sorting problems, search problems, path problems, combinatorial problems, etc.) so that students can master the algorithm design strategies and analysis methods. We prepare many problems for each issue in the online judgment system (OJS). By using OJS, we carry out all experiments and examinations in the specified times. After solving some problem, students submit the code to OJS through browser. We can output the student codes to further analysis in the background management system. Online judge system provides an open, independent teaching platform for students to learn the course knowledge. With OJS students can submit their code at any time and any where.

Abstract: Workflow technology continues to be subjected to on-going development in its traditional application areas of business process modeling and business process coordination [ .It can improve the efficiency and manageability of an enterprises daily teamwork .Traditionally, it is not easy for the workflow modeling method to describe the complex business process clearly and intuitively [ .In this paper ,we improve the role based workflow model and introduces definition and enactment models to characterize workflows. In the way ,flexible modeling and enactment of business process is supported allowing changes even during execution.Finally,an example of Financial Reimbursement System is demonstrated to prove the convenience and feasibility about the method mentioned.
