摘要：
Among the numerous EMISs(Education Management Information System), the ubiquitous problems such as the difficulties for data sharing and the limited abilities for interoperating make the information systems of different colleges and different departments isolated. Therefore,the committee of Educational Information Technology Standardization(belong to Ministry of Education of China) issued specifications,Education Management Information System Interoperability Framework, which are good solutions for those problems. In this paper, the framework structures and data exchange models as well as the message formate of EMIF are discussed. The systematic analyses for functional demands of a Zone Integration Server (ZIS), the core component of the EMIF, are made, also its functional model is given. The implementation mechanism and algorithm based on message services, message transportation, and message management for the key functions such as message processing are given, and an instance for providing message processing is presented. Finally, the structure for the data interoperation among multi-EMIS on the campus net based on EMIF is discussed. ©2009 IEEE.

摘要：
To determine the need for the simulated training of e-commerce activities prior to working in the real environment, we studied the views of the undergraduates from several aspects. Two hundred university students were asked what the real problem was when they learned in e-commerce courses. Next, they were surveyed to inquire what knowledge do they really need when they go to their work positions and what type of job do they expect to. Finally, they were asked whether using a simulated training platform would be beneficial. Through analysis the aspects which contained above we know that simulation should be incorporated into the education of e-commerce students as a tool to practice their hands-on abilities prior to working. And from the survey we also obtain some useful information and reference that may help us to design our electronic commerce training platform.

摘要：
The construction and improvement of teaching evaluation system is a very important part of teaching work in recent years. Along with the constant development of network-based study, a comprehensively scientifically and objective evaluation is increasingly important. To establish an evaluation system of network teaching is the needs of scientific management of teaching quality. Moreover, the study on the comprehensive evaluation of fuzzy mathematics is a new developing field in recent years, which aims at evaluating the appraisal object objectively, fairly, reasonably. Therefore, fuzzy comprehensive evaluation in network teaching is of great significance. By using different evaluated methods, the paper tries to find out a network teaching evaluation model which is based on fuzzy comprehensive evaluation, aiming at evaluating the network teaching fairly and reasonably. ©2009 IEEE.

摘要：
A novel load balance technique based on rumor mongering in structured P2P networks is presented in this paper to address the hotspot problem when using DHT P2P networks as the distributed index systems. The basic idea is making use of the periodical topology maintenance communications to piggyback and spread popular information by way of rumor mongering in background. It is shown in the paper that, this rumor mongering technique is able to spread information quickly among nodes in structured P2P networks without introducing additional communication overhead, which effectively reduces load on hotspots.

摘要：
Web service is a new service-oriented computing paradigm which poses the unique security challenges due to its inherent heterogeneity and highly dynamic nature. A key challenge in web service security is the design of effective access control schemas. However, traditional role-based access control (RBAC) model can not meet the dynamic and context sensitivity features of web service demands. In this paper, we propose a context based dynamic role based access control model (CDACM) for web service. Our approach grants and adapts permissions to users based on a set of contextual information collected from environments of the system and users. The model can consummate the privilege management for web services access control, effectively enhance the security for web services applications and produce more perfect mechanism of access control for web services. ©2008 IEEE.

摘要：
With the development of virtual studio technology, the application in the field of education has been emerging in China, 'especially for high-quality educational resource authoring. However traditional virtual studio systems have not been widely deployed. The reason is not only the large investment but also the complexity of the operation and maintenance of the system. Thus new virtual studio system meeting the actual needs for education applications should be developed. In this paper a novel low-cost virtual studio system with convenient operating interfaces is presented. The system provides convenient and integrated functions and interfaces for high quality education resource authoring, while only one system operator is required. With the help of this system, dramatic and vivid presentation of the education resource can be generated, bringing the improvement of the efficiency and quality of education activity. ©2008 IEEE.

摘要：
Unequal error protection on video transmission is widely used to combat with bit errors in the wireless channel. However, current UEP schemas are based on heuristic approaches and taking no account of the characteristics of human visual system. In this paper, a novel unequal error protection schema for wireless H.264 video transmission based on a modified Perceived Motion Energy (PME) model is presented. According to the sensitive characteristics to video motions of human eyes, the proposed modified PME model taking account to the encoding features of H.264/AVC standard to analyze and model the motions in H.264/AVC encoded video. Based on this model, the video bitstream is divided into several quality layers and unequal error protection is designed to protect the layered bitstream for the transmission over wireless channels. Experiment results show that higher video transmission quality is obtained. ©2008 IEEE.

摘要：
With support of multiple learners and multiple roles in a learning activity, IMS Learning Design (LD) specification provides a collaborative scenario for participants. However, IMS LD provides insufficient support for interaction among learning activities and can not dynamically integrate learning resources to meet the continually changing service requirement. In this paper, we propose a BPEL-enhanced requirement driven learning management architecture to address the issues of personalize adaptive learning. Our approach models the learning activity by combining IMS LD with BPEL and matches optimal learning sequence base on CBR (Case-based reasoning) method. By providing expandable learning sequences flexibly, it satisfies the different actual demands for personalize learning. ©2008 IEEE.

摘要：
Personalized teaching systems are gradually introduced into the teaching field along with the development of information technology and many fruits are achieved. But people must re-examine the teaching and learning based on information technology with the arrival of Web2.0 era. There is no doubt that the development and utilization of Web2.0's ideas and technologies have been bringing new vitality to teaching and learning. How to make better and more efficient use of the technologies and ideas in teaching and learning should be paid more attention. So, in order to facilitate teaching and learning efficiently, personalized teaching system need to be fully researched. This paper is to analysis the technologies and ideas of Web2.0 and their value to the personalized teaching and learning, construct the personalized teaching system framework based on Web2.0 and then analysis and design its personalized modules. The purpose is to combine Web2.0's technologies and ideas with teaching system design for teaching and learning. ©2008 IEEE.

摘要：
Highly detailed geometric models are rapidly becoming common-place in computer graphics. But sometimes it is often desirable to use approximations in place of excessively detailed models to control processing time. This paper introduces a surface simplification algorithm that based on edge-collapse. The algorithm uses Quadric Error Metrics to confirm the position of new vertex in order to control the error, and gives a new cost function of the edge cost. This algorithm can preserve the important feature of original 3D model efficiently and control the error effectively. The results show that this algorithm is memory efficient, allowing the simplification of very large polygonal models, and can rapidly produce high quality approximations of polygonal models. ©2008 IEEE.
