Abstract: We have presented a new vision solution method which has good real-time characteristic. It satisfies the convergence characteristic in some regions, which is the premise for running of our solution method. In this paper, we present one convergence region and provide a detailed account of proof for the convergence region. Proof for convergence region can provide theoretical basis for vision solution method.

Abstract: In mobile Ad Hoc network, node movement makes the network topology change frequently. In order to improve the stability of routing, a new routing protocol PPC-MAODV (Path Prediction compute based multicast Ad-hoc on-demand Routing Protocol) is proposed in this paper. This protocol takes the path stability into account and reduces the times of route repairing and route reconstructing by selecting the path with the high stability and less hops to transmit data. Simulations show that the PPC-MAODV proposed in this paper is valid and can reduce the packet delivery ratio and end-to-end delay.

Abstract: Through the questionnaire survey on the following five aspects: the developing status of multimedia teaching in physical education of Chinese universities, the construction progress of multimedia teaching technology in P.E. courses of universities, P.E. teachers’ self-positioning in making multimedia courseware, multimedia courseware’s distribution in physical education materials of universities, as well as the teaching effect of multimedia courseware in physical education of universities, the following conclusions can be reached: multimedia teaching technology has gradually become more and more important to physical educators in universities. Some universities have already begun to make attempts in multimedia physical education. Considering that, the paper has also constructively made prospective proposals for multimedia teaching technology in P.E. courses of Chinese universities.

Abstract: Data mining based on data stream has become one of hot research fields. In this paper we present a novel algorithm for clustering data streams based on dynamic grids named DG-CluStream. DG-CluStream partitions and prunes grids dynamically, improves the accuracy of grids gradually through saving feature tuples of grids. The algorithm can discover clusters with arbitrary shape and is more efficient than those static methods due to a notable decrease on the number of the grids. Through fading coefficient, DG-CluStream can also deal with the problem of concept drifting efficiently. The experimental results on real datasets and synthetic datasets demonstrate promising availabilities of the approach.

Abstract: With the rapid development of wireless mobile communicational technology and the growing demand for lifelong education, mobile education has become a convenient and effective way of education and received considerable attention and research. To further meet the needs of study at “any time, anywhere, any style” for teachers and solve the problem that the difficulty of continuing education and training of in-service teachers, this paper uses the wireless communicational technology of 3G to create the platform for teachers’ training by the main mobile terminals of mobile phone. It will promote the better service under the concept of mobile learning and it has great significance for solving the problems in the traditional training and supporting teachers to enhance the professional development.

Abstract: This paper analyses the main reason why Korean commodities can be so fashionable throughout Asia and even the world by going through Korean products’ design from three aspects, harmonious design, appeal design and lovely cultural design, at the same time, it expounds the secret of South Korea's design’s leading position from its Cultural connotation and scientific and technological content. Owing to its many advantages, such as Exquisite design, reasonable man-machine, Korean commodity brings people a sense of emotion and enjoyment while using the products.
