Due to the rapid development of network technology, the structure of computer network is increasingly complicated. The traditional random network model is difficult to characterize the topology of current computer network. Complex network theory provides new view and thinking to study in this field. In this paper, we give a probabilistic model to examine the evolution of computer networks by random duplication processes of node degree as well as the preferential choice mechanisms. The model is solved exactly,for large network. We demonstrate that both the degree distribution and the triangle distribution have stationary properties. When the size of the network tends to infinity, the degree distribution behaves as P(k) proportional to k(-3) and the average clustering coefficient C is independent of the network size N.

Based on the analysis of the traditional forward maximum matching word segmentation algorithm and the characteristics of the principle on the basis of the results of the use of word frequency statistics, we design a new structure of the dictionary, a dictionary based on the new structure to improve the matching algorithm are the largest. After time complexity analysis and experiments, the improved forward maximum matching algorithm can further improve the efficiency of segmentation.

Along with the gradual maturity of distributed computing platform REE, J2EE has become the current mainstream enterprise application and development platform and J2EE/EJB technology makes system have a good technical foundation on expansibility, portability and flexibility. Against the background of a certain logistics management system development, an analysis and design of MVC design pattern under J2EE architecture is carried out in this paper. On business layer, the entity bean is encapsulated by session bean, which normalizes the client access, reduces the coupling between business layer and client end, centralizes security management and transaction control and improves the performance. Meanwhile, the value object is introduced into the system to encapsulate the interactive data between Web layer and business layer, which decreases the network overhead of the system.

In the computer curricula teaching process for the four-year students of our high education, there is an evident problem, which exits so long a time, that too often the theory is focused on while the practise is marginalized, consequently, posing another protruding matter that the education goals could not meet the practical needs of the society development and enterprise manufacture. Given the characters of case teaching method and the reality of undergraduate computer curricula teaching, this paper presents the principle of case choosing in the case teaching process, along with the basic methods of case design and teaching procedure scheduling. It also raises one practical case in the multimedia technology course. It is proved by the teaching practice that the case study and practise method taken in the process of the undergraduate computer curricula teaching benefits a lot to the students: they could comprehend and master the theories better;their practical ability could be enhanced;the competitiveness of employment would be promoted.

The purpose of the present article is to examine the implications of the pragmatic web for the research and development of educational technology. It is argued that, beyond knowledge acquisition and social participation, technology-mediated learning environments based on a semantic and pragmatic web have the potential for facilitating creation and advancement of knowledge. In order to capitalize on the increased information and social connectivity of the novel ICTs, it is essential to develop adaptive informatics that coevolves with knowledge-laden social practices. The present arguments are grounded on a vision of "Metaweb" which is elaborated further from the perspective of social practice. Implications of the position presented concerning the research and development of technology-mediated learning environments are discussed.

Skillful management of the various types of documents used in intelligent activities and their efficient utilization are important. However, most available systems target only a single type of document (e-mails, Web pages, etc.) or are not adaptive enough. A more promising approach is topic-centered document management. A topic-centered document management system is described that changes its own functions and interfaces adaptively.
