Abstract: the student achievement management system is a typical application of managing information system (MIS), its development mainly includes the backstage database the establishment and maintenance of and front-end application development two aspects. For the former requirement to establish data consistency and integrality and security of data. For the latter requires the application program function complete, easy to use, etc. Use MICROSOFT ASP development tools, background database ACCESS, build system application prototype in a short time, then, to the initial prototype system needs iteration, constantly revised and improved, until forms the user satisfied feasible system.

Abstract: The energy of the node in Wireless Sensor Network (WSN) is supplied by the battery, and the energy is limited. In this paper, the more energy-efficient WSN routing protocol is improved, to support the operation of the WSN to prolong the lifetime of network as much as possible. On the basis of the existing Low Energy Adaptive Clustering Hierarchy (LEACH) routing protocol, a new Geography and Energy Cluster Algorithm is proposed. The new algorithm not only improve the biggest connectivity of the clustering routing protocol, but also balance the energy consumption of the whole network, and achieve more energy-efficient . The results of the simulation of the software indicated that the new improvement of GECA protocol is more efficient and prolongs the WSN lifetime.

Abstract: This paper elaborates the systematic structure of query by humming, tries to explore and improve it and puts forward ideas to build a new music retrieval system.

Abstract: Museum digitalization has broken a lot of limitations of physical museum. The rising of new media platform and the maturity and application of digital technology and mobile communication technology, especially the Web3D technology, have provided sufficient condition and broad foundation for the digitalization of museum. Based on the analysis of the status quo of the development of museum digitalization, this article briefly discusses the practical significance and value of the construction of digitalized platform of museum, and conducts in-depth exploration on the construction of digitalized platform of museum based on the Web3D technology, the three main function modules and other issues.

Abstract: To balance wireless sensor network energy consumption and reduce transmission delay, this article proposes an adaptive data aggregation based on non-uniform clustering algorithm. In the phrase of Unequal clustering, it put forward the concept of “cluster radius”, made it increase along with the distance between monitoring area and sink node, in the phrase of data aggregation, when data loss rate changed with cluster radius dynamically, adjusted aggregation factors in each cluster adaptively, and aggregation factor decreased along with the increase of cluster radius. Experimental simulation shows that the adaptive aggregation based on unequal clustering algorithm reduces the network energy consumption by 18% and the network transmission delay by 47.2% than the unequal clustering full aggregation algorithm in literature [7], it prolongs the network lifetime and reaches the purpose of real-time monitoring.

Abstract: Four generation mobile network has been more than two years of commercial experience in the word. Two standards of four generation networks: LTE FDD and TD-LTE, the former dominant in the market, but the TD-LTE network is only a small proportion. With China operators obtain TD-LTE licenses, China's huge potential market for TD-LTE will soon become a reality. Market process of TD-LTE will be more difficult for impact of LTE FDD, and concern balance role of policy and market. Market research and policy analysis of TD-LTE will continue to deepen, which will influence the development of TD-LTE industry chain. Therefore, it is very necessary to do more research and analysis on market and prospect of TD-LTE. Analysis domestic and international markets, combined understand LTE network architecture.

Abstract: the computer database has been widely used, it refers to is stored in the computer, data are formed in order to achieve a certain purpose, the construction and maintenance requires high technical content, so you need to improve relevant management personnel's quality, attach importance to database users of technical training, to ensure the good operation of database. From the database design, database, network building, computer database management, database maintenance and so on several aspects of the database construction and maintenance management related issues were studied.

Abstract: Tag technology how to combine with personal information management model is a personal space management information system of data management and sharing of the premise, based on information search in the traditional personal information management efficiency is low, can't share problem, put forward based on the tag tree organization of local data, based on a tag cloud organization model and the algorithm of global data, to construct a distributed and integrated data environment. System performance test results show that the proposed algorithm can effectively improve the precision of personal space management information system, reduce the response time.

Abstract: In order to monitor and control the security isolation system remotely, this paper analyzes the implementation technology of simple network management protocol (SNMP) and secure file transfer protocol (SFTP), aiming at the problem that SNMP can not send a large amount of data, proposes an approach that extends the Manager/Agent model of SNMP, with customing flag OID variables and manager configure the file transfer-realated OID variables adaptively in the MIB of SNMP agent, call the SFTP client embedded SNMP agent to upload and download the configurati on file from specifies designated SFTP server, and parse the configuration file in order to update security isolation system rule base or the virus database version. After Networking Test, The approach can be simple and efficient implementation of the safety isolation system for remote monitoring.

Abstract: Dedicated users are usually the great energy consumers, and also the key objects of the national energy saving and emission reduction. Energy-saving diagnosis and energy audit work is an important foundation for the promotion of energy saving and implementation of the "Green Action". However, currently energy-saving diagnosis and energy audit work is only accomplished by specialized qualified energy-saving service units, which rely on manual site detection that costs a large number of time and effort, while it is very inefficient. Therefore, the development of intelligent system of energy-saving diagnosis and energy audit based on dedicated users has significant economic potential. The intelligent system is introduced in this paper, including hardware subsystems and software subsystems. Hardware subsystem consists of the energy-saving diagnosis device. It can be implemented effectively by online monitoring and data records of the large power consumers. It can store at least one week’s data. Software subsystem is an energy audit software platform developed in the environment of Visual Studio 2010. It can calculate saving potential of energy consumers and automatically generate the audit report. Thus using this system, the power grid corporations may get rid of dependence on energy-saving service corporations, and implement electricity energy-saving analysis and rapid energy audit work to all kinds of energy consumers independently.
