Abstract: The demands of safety in the e-commerce based on the Internet was discussed in the paper. And it started from the threats that e-commerce faced. And then some technology used to reinforce the safety of the e-commerce was described, including the safety demands of e-commerce, the safety of network. Some safety technology were discussed such as the encryption technology,the authentication and the safety protocol etc.

Abstract: Flex is a WEB application development platform based on Flash technology and an excellent RIA development tool. It can communicate with all the current mainstream server technology through various communication technology, wherein, RemoteObject communication method is the most effective and popular method: In the development process, RemoteObject is the key to the whole system in the design of client invocation pattern. The paper combines the technical feature and various design patterns of RemoteObject component. The designed remote agent pattern can greatly improve the code reusability and maintainability under the premise of not influencing the performance, and improve the development efficiency and operational efficiency, and it has high application value.

Abstract: With the fast development of the science and information technology, the social level of China has developed and people’s living standard has also been improved. The development of information technology has made the computers be used widely in many fields as well as the main power. For the development of economy and the improvement of comprehensive strength, people have paid more and more attention to education. With the scale of high schools especially the labs grows quickly, the schools have all equipped enough hardware equipments in order to train high-quality talents. In this situation, we need improve our management level so that we can make full use of every kind of resource.Nowadays, the labs management under the background of JAVA,designing effectively the management system is on the basis of B/S model and does effective experiments.

Abstract: This paper studies the computer network traffic related subjects background first, and analyzes the research status quo of network traffic monitoring, putting forward the main content and the research target. This paper introduces the key technology, network traffic monitoring system for the topological design and analysis of computer network traffic monitoring system, computer network traffic monitoring system for the overall design, network traffic monitoring has been basically achieved demand. From the point of view of network users and network operators, network traffic monitoring can improve the scientific and rationality of network management having important research value.

Abstract: With the development of electronic technology and network technology, the use of power line carrier as a signal for transmission by the people more and more attention has been increasingly widely used. In this paper, the design of data acquisition module is proposed based on the SSC P300 power line carrier communication. The overall design mainly includes four parts, that is, the main processor AT89C51, data acquisition chip TLC2543, SSC P300and the power line simulation .In order to achieve half-duplex data communication through the 220V power line, we use the more advanced spread spectrum technology, and select both Chip SSCP300 and P111 PL to meet the criteria of CEBus. The experiment results indicate that the design of data acquisition module can obtain much better quality of communication and much stronger anti-jamming.

Abstract: Community sports informatization is the optimization of community management and community service and an important means to improve to meet the physical needs of community residents. According to current situation of community informationization development combined with the community sports construction principle, the construction of community sports information construction frame of theoretical system provides the theory support for the benign development of community sports to make full use of the community information platform. The community sports management platform provides a convenient and efficient community sports management system designed in this study for the community sports management and build a community sports exchange feature rich platform for community residents. Other street community can combine their own situation with reference to the research and design of the community sports management information system.

Abstract: In this paper, the virtual reality technology and its hardware and software development platforms are introduced. Focus on the characteristic of non-lethal ammunition, it elaborates on the design ideas, system structure, key technology of developing virtual operation and training system with tools. The system provides a new experimental platform for the armed forces to handle emergency events as it simulates a more realistic battlefield situation.

Abstract: The testing system designed by us aims at campus users. It can be considered as a subsystem inside the campus web, which not only can save papers to alleviate the schools expenses but also provide references for macro management of teaching for the administration with the help of analytical function of scores generated by the system.

Abstract: Lotus OA is widely used in some large departments. Because of its special architecture, it is difficult to develop a corresponding native mobile application. This paper propose an economic structure to develop native mobile application for Lotus OA. Use this structure, traditional Web developer can directly participate in the Lotus mobile development. This paper introduces our development process, explain the reason why we choose this structure. Also, this paper compares our software structure with other software structures, the result shows that our structure is more economic than other structures.

Abstract: We consider the scenario of cognitive relay networks, where the cognitive relay is equipped with multiple antennas and the cognitive destinations have only one antenna due to the size and cost limitations. Aiming to maximize the signal-to-interference noise ratio (SINR), we develop the optimal beam-forming scheme for the relay case. The proposed scheme is based on minimum mean square error (MMSE). The theoretical results are validated by simulations. Simulation results show that the proposed scheme has a considerable performance.
