With the popularity of e-learning, to construct a perfect e-learning environment has become a popular research topic in the field of modern distance education. Cloud computing is a new computing model which is based on the grid computing, it is the core technology of the next generation of network computing platform, especially in the field of education, cloud computing is the basic environment and...
The self-similarity of complex networks has broad practical backgrounds, yet the self-similarity of network has been rarely studied. One of the problems is to explore the origination of self-similarity in real networks. For this purpose, we proposed the information transfer model in network. The volume dimension integrating the information transfer model is given to analysis the self-similarity of...
Data visualization can represent clearly the data difference and data change trend. It can help scientific researchers find the rules and trends behind the data quickly. In the process of monitoring eco-environment in Three Gorges reservoir area, a large database (>TB) of data has been acquired. How to fully utilize these data to analyze the trend and evaluate the eco-environmental impact of Three...
SOA is a software architecture. It is a real solution to integrate education resources and enhance resource utilizes. This essay introduced SOA's principle, structure and reference model of application. Based on this, it designed a SOA-based education resource service system. It used Web Service, WSDL, UDDI, SOAP and CELTS to implement the system. Through the system, we can use and develop the education...
In Web information systems (WISs) forms are one of the major interaction instruments that allow users to enter data and thus direct the communication process with the system. In this paper we approach the capture of forms in a conceptual WIS model. Abstracting from low-level forms processing a form can be considered to be part of an interaction type that can be formalised by a generalised view. In...
The explosive increase of resources available on the World Wide Web (WWW) not only provides users with valuable information, but also makes the information usage difficult. On the other hand, nowadays it is a trend that more and more people cooperatively and collaboratively work together to complete a task. Efficient coordination and cooperation is required. Thus a cooperative information system is...
