摘要：
With the development of virtual reality simulation technology, virtual campus has become an important field of research. Oversimplified and lack of reality in most of traditional campus's illustration; as a result, there are limitation for its practical value. The 3D model of virtual campus not only offers the natural, real, visual representation of real campus, and also keeps good interaction with users, so that audience could look through and experience with illusion that they are actually right there within the campus. This paper discusses the detail of 3D model simplification based on VRML and the shortest path in roaming. This issue can be solved by using of the LOD and GIS technology and develops a virtual campus navigation system. Example of Central China Normal University proved the feasibility of these technologies, and enhances the effectiveness of the system.
摘要：
In recent years, the network attack become more and more widespread and difficult in against. The traditional technique, such as Firewall is good, but when malicious traffic originates from inside network or enters through a hole in the firewall you may need another line of defense to protect you. This is a article introducing the concepts of IDS, what they do, the functions they serve, the classification of IDS, how you might use an IDS to monitor for and detect suspicious or malicious activity on the network and the different methods of intrusion detection that they may employ.

摘要：
The educational information resource management system, which is based on SOA, achieves the goal of "change as need" for the system, ensures rapid update of the businesses and functions, improves the services of reuse, shortens the system development cycle, and cuts down the developed costs. This paper firstly analyzed the current educational resources management system, and found the existing problems, so it is suggested to developed resource management system based on the SOA, and it also demonstrates the advantages of the SOA-based resource management system. Then the paper introduces detailedly the Overall design of the educational resource management system based on the SOA, the system functions, and the system business process, and this paper also focuses on the implementation of the services related to the system, services Registration, discovery and call and the key technology of the services combination and flow arrangement.

摘要：
One of the major design issues in heterogeneous wireless networks is the support of vertical handoff. Vertical handoff occurs when a user with a multi-interface terminal changes association from one type of wireless access technology to another while maintaining an active session. It is believed that vertical handoff decision will be based on multiple criteria. In this paper, new handoff criteria are introduced along with an improved vertical handoff decision strategy based on fuzzy logic. A performance study using the integration of cellular networks and WLANs as an example shows that our proposed vertical handoff decision algorithm can reduce the handoff call dropping probability as well as unnecessary handoffs in heterogeneous wireless networks.

摘要：
The mobile electronic commerce is a business activity which is organically synthesized with mobile information equipment such as the handset and the personal digital assistant and Internet. The mobile communication technology and other technical perfect combinations have created the mobile electronic commerce along with the globalization information technology revolution. The improvement enterprise service flow, the promotion enterprise operation efficiency has already become one of the targets faced on enterprise's electronic commerce goals. Basing on it, a mobile E-Business system based on Bluetooth was proposed and realized in the paper. Mobile E-Business system used Bluetooth technology as the communication media.

摘要：
Most visual simulation systems are developed based on Vega. They are unable to make smooth operation because of large volume of data. In this paper, some key techniques about how to optimize the 3D scene model are proposed in order to improve the operating efficiency of the visual simulation system. Including simplifying the 3D model, cutting down the data stream of texture, techniques for creator modeling, setting LOD node, Optimizing the hierarchy structure of the database...etc., An experiment show that compared with the original system, the EMS memory of the optimized one is less, the data stream is smaller, and the time to load is shorter.

摘要：
With the proliferation of computer graphics and computer animations, 3D models are as plentiful as images and video. This has made the retrieval for specific 3D models become a vital issue. And now, content-based retrieval of 3D models has therefore become an essential research topic. In this paper, we describe a simple, faster and effective method for 3D shape indexing, and an enhanced feature, called silhouette descriptor, is proposed for 3D models retrieval. The propose method is based on a multi-view approach, which keeps 3D models coherence by considering a set of images in specific view direction simultaneously. Experimental results show that the proposed method is faster, simpler and most efficient.
