Abstract: With the multiple field databases resources to be enriched, users hope to access and use these databases freely and comprehensively. But phased establishment of application and particularity of Application results in inconsistent application platform and heterogeneous data management systems . To make users access databases transparently, the data Integration of heterogeneous databases is the problems being solved. The paper proposes a model of data sharing providing the user with a unified view and establishes webGIS service, making the multidisciplinary and spatial data display validly and solidly.

Abstract: The previous studies showed that the concurrent multi-path transmission (CMT) schemes can only play their advantage in the narrow-band networks (the most CMT experiments use 2M bandwidth). In this paper, the authors investigate the performance profits of CMT schemes with various network bandwidths. The simulation results show that the CMT schemes can work better in broad-band networks (e.g., over 20M bandwidth) than in narrow-band networks. This also implies that the CMT schemes have the potential to be applied in the field of multimedia transmission.

Abstract: At present, IPv4 addresses are facing depletion and do not meet the requirements of the development of the network.Compared with IPv4 protocol, IPv6 protocol has obvious advantages in technology. The next generation internet research based on IPv6 protocol is a hot research field in campus network, now the IPv4 network is also in urgent need of upgrading to IPv6 network. Introduces the dual stack and tunnel technology to upgrade the campus network, analysis of the present situation of the campus network, and design an upgrading scheme in this paper.

Abstract: . This paper describes the design of the telecommunications data warehouse interface part and development process of the ETL. Use of the data warehouse organization and storage method, carry on data analysis and business decisions effectively for the telecommunications services.The interface mainly undertakes the tasks is standardizing transfer mode of data among the various production systems. ETL's process is the key of the whole data warehouse. In the Text, described in detail for Its function framework and software deployment, and according to the data interface specification to describe the Interface environment configuration. Through the establishment of this platform, the data of the Production systems can be harmonized. And provide a strong background support for development and display of the front, benefit the policy-making level more accurate grasp development situation of the enterprise.

Abstract: Multiple sensors with ZigBee wireless communication module composed of environmental monitoring network platform. With ZigBee server/gateway support, this platform could achieve the connection to the Internet, remote monitor temperature, humidity, smoke, noise, etc. through the Internet network, and achieve ZigBee LAN monitoring and status display. The main contents of this paper are as follows : 1the analysis of ZigBee protocol stack layers of protocol network routing protocols, network topology , etc. 2the research of networking in the form of ZigBee, to build the ZigBee network with a star network topology. 3research ARM platform, understand the Linux operating system, and build embedded Web server. Meanwhile, ZigBee server hardware and software platform is built on this ARM platform, porting ZigBee transceiver modules to realize the ZigBee-based wireless gateway. 4the research of checking buildings , humidity, smoke , noise, heat hydroelectric and other states which need to be monitored remotely through servers.

Abstract: The development of modern volleyball sports has become much more closely connected to the application of computers, and computer has been widely used in many aspects including sports training, game statistics, sports meeting organization and management, and sports teaching. Having searched the sports research documents in last 20 years, I found that the application of computers research started early among sports staffs in China. And the research content is composed of computer software development of game statistics, CAI course material development based on WEB in colleges, CAT software development of students sports result in colleges, sports statistics software development based on VB, sports meeting items arrangement and management software development, and remote network visit technology in sports meetings in colleges. However, the software developed is comparably low in quantities and quality, especially not popular in practical application. This condition has restricted the development of volleyball to a certain extent.

Abstract: In this paper the author introduced the application of computer drawing technology in sport drawing, the function and the skill tips of usual drawing tools. Also the teaching organization chart and sport bogdy drawing were put into drawing in practice, which soled the difficulties in writing teaching plans and teaching in classes. In this way, the study difficulty was reduced, and the time spent on mastering an action was shortened. Therefore the teaching result and quality was greatly improved, which promoted the application of computer in sport and enriched the function of sport drawing.

Abstract: In this paper the author introduced the application of Word drawing function in sports drawing, the function and skills of common drawing tools, and solved the stubborn problems in writing teaching plan and class by drawing ground device, queue type, teaching organization, and sports human body in practical examples. In this way, the study difficulty level was reduced, the time spent in mastering actions was shortened, the teaching effect and quality was greatly promoted, the application of computers in sports teaching was propagated, and the teaching patterns of sports drawings were enriched.

Abstract: As the wireless sensor network node battery is limited and changing battery is difficult, we did research on feasible energy conservation design technology. Paper analyzed energy consumption and the proportion of network node in work station of dormancy, data dealing, and communication and so on. Hardware circuit was promoted through power partition, signal isolation and low energy consumption chip application. Software program was optimized through state machine combined with differential compression coding. Then the purpose of extending network life can be reached. The experiment result shows that the energy conservation design can reduce the energy consumption greatly and extend the network life 2~3 times.

Abstract: Delta laboratory management system was designed for Delta automation laboratory in XMUT. This Laboratory management system was based on LAMP platform which would provide the experiment reservation service and allowed students to upload or download related material. Real time stream video of laboratory was provided by the server of MJPG-streamer for the surveillance.
