Abstract: By the analysis of motion Geometric features and Continuing feature that the motion capture data of the BVH format showed,Motion feature extraction method was proposed in this paper to preserve the motion original features in the maximum extent and marked motion data,improved the speed of motion data retrieval,and also provided a new method for rendering of motion characters in the virtual environment.

Abstract: This article based on the level of details (LOD) technology of current geometry layer research, introduced the thinking of technology into the behavior layer of virtual environment characters rendering, as the basis from the important level of the characters and the characters of their location, used different levels of details on the rendering of characters, made a balance between characters rendering time and characters facility and reduced the rendering time of large-scale virtual scene, made an increase the number of virtual scene characters with new methods.

Abstract: With the help of information technology, we study the relationship in-depth with martial arts, to promote the development and progress for the martial arts, so that it can provide a theoretical basis for the strategic decision of the martial arts development, offering innovative ideas for the reform of heritage protection, teaching management and training of Wushu.

Abstract: This paper introduces the PLC in the application of network technology, the characteristics of information channels of power line are analyzed, this paper discusses two kinds of modulation method, and contrast the FSK and OFDM modulation technology to make clear their respective features, finally summarizes the PLC access network technology based on OFDM modulation technology, the remarkable advantages of OFDM modulation technology are defined.

Abstract: This article interprets the current development status of trunking mobile communication system at home and abroad, makes a detailed analysis of the two existing architectures of trunking technology, introduces the demand of digital trunking broadband in China on the basis of the analysis on current situation and development trend of trunking mobile communication system. It also presents two types of domestic technical scheme in combination with the features of broadband trunking mobile communication systemr abstract.

Abstract: This paper introduces a portable environmental information collection and dissemination terminal based on embedded hardware platform, which uses wireless mobile communication link, builds data link, receives the collected and analyzed data from a Towns and Villages Environmental Multi-source Data Processing Base (TVEMDPB) which locates in the monitoring area. Then the terminal displays these data reasonably and vividly through a variety means. At the same time, the terminal integrates GPS and related data processing module to provide information feedback for the Towns and Villages Environmental Multi-source Data Processing Base. By doing this we can build portable terminal platform which can send environmental information and emergency instructions. And the terminal will form a mobile node of the environmental information system. In the end, achieve the seamless connectivity between the distributed towns’ and villages’ environmental early warning system and the monitoring data, real-time evaluation and warning for the towns’ and villages’ environmental pollution.

Abstract: Along with the increase of living pressure, releasing pressure by psychological counseling has become an important need for people. Psychological counseling management information system based on network has the advantages of better privacy, more flexible form, more equal emotional interaction, more open source and more convenient and quick work when it is compared with traditional methods. Based on those characteristics, the authors have developed a psychological counseling management information system based on ASP language. The whole system can be divided into three modules: user management module, order and message leaving module and BBS module. In this article, the design of database and system modules is introduced in detail.

Abstract: Human life and work are affected by PM2.5, so it is very necessary to get the real-time detection of PM2.5 every day. Remote monitoring is achieved by the LM3S8962 with Ethernet module as control core, and then the detect signals about PM2.5 air quality are transmitted by Ethernet communications. It has been proved by our experiment that Air quality testing data can be obtained in real time by experiments. It can be conclusion that the data of experimental is right by comparing.

Abstract: In this paper, we set one models in total, based on taking it into account that two-lane highway capacity, security, and traffic flow efficiency in different traffic load conditions. We propose one evaluation indexes, that is, average number of vehicle decelerating and following others, free passage probability, average number of overtaking, the accident probability, and the average traffic speed of vehicles, to analyze the change rule of every index under different vehicle density.

Abstract: Along with the development of the computer technology, communication technology and information security, people are enjoying the convenience of new trade patterns e-commerce bring by open web. At the same time, it also have to face all kinds of security problems in e-commerce. In this paper, it analyzed the network security technology in electronic commerce, put forward the design scheme of network security platform that can effectively ensure the smooth progress of e-commerce activities. The study of the security problems in e-commerce, has special important theory value and practical significance.
