In education field, presentation tools like PowerPoint are widely used and play important role in creating learning content. But the file formats of those presentation tools like ppt do not support web page format which is suitable for Web publishing. Those presentation tools file formats are usually need further format converting process, like converting ppt files to web page files or to swf files. To solve the problem, the paper designs and implements a simple presentation tool, and the file format is based on Web pages. The file of the simple presentation tool is composed of several web pages based on vml supported by IE, and each web page is relative to a slide, that is mean editing slide is editing web page. So the file generated by the simple presentation tool does not need further file format converting, more suitable for web content publishing. The paper introduces the architecture of the simple presentation tool, and its basic functions including textbox edit, picture edit, graphic edit, slide edit.

A new access algorithm in cognitive radio systems is proposed inthis paper, which can decrease primary users' access delay effectively and guarantee the access throughput fairness among primary users and secondary users. In the time domain, primary users apply 1-persisten access policy and secondary users apply exponential backoff retransmission policy; while in the frequency domain primary users select several suitable subcarriers as access channels and secondary users select only the subcarrier with the least interference temperature as access channel. Simulations confirm the perfect performance of the proposed algorithm.

Based on a creative sliding mode prediction model, a novel sliding mode observer (SMO) design method for discrete-time nonlinear uncertain systems is presented in this paper. By combining feedback correction approach, the observer states can close to system states as exactly as possible, and chattering is eliminate simultaneously. Because of the employing of receding horizon optimization technique, the observer compensatory term can be optimized continuously and on-line. The proposed method guarantees the SMO is robustly stable. The satisfying properties of the SMO are verified by a numerical example.

The paper completed all the correction of constellation error and receiver channel error. It was brought forward a comprehensive scheme for position error correction. The experiment platform was based on Superstar II GPS receiver and Matlab. It mainly corrected the position error such as satellite clock error, ionospheric error, tropospheric error, the earth rotation effect etc. Moreover, ionospheric delay error was corrected for about 14 m by Klobuchar model; tropospheric error was corrected for the average value of 4.05 m by the altitude angle module and so on. Especially, the satellite clock error was corrected for 3.1 m related to IGS by empirical formula. The user clock error is the max error with magnitude of 104~105 s to affect position result. Finally, these methods improved the positioning precision to 17 m. The result of experiment has proved the validity of these correcting methods, accumulating much experience for the next investigation.

In some cases chaos is equal to instability, which means a tiny disturbance of the initial value to a system will brings a big change in the outcome of the system. Scoring models from credit system also has chaos phenomenon which leads to a paradox that similar people take so different treatment that we can not accept. This paper describes chaos that happens in the credit system and gives an example to explain it.

According to the computer is more and more powerful; the computer animation is widely applied in the game, entertainment, and scientific fields. When making a computer graphics (CG) animation, firstly we build three-dimensional models, and then attach the motion sequences on these models. Either key-frame setup or motions capture systems can help to get the motion data, and both of they need considerable work. Thus, the motion data cost expensive, and need the copyright protection. In this paper, we'll develop the digital watermarking technology for the motion capture (MOCAP) data. When watermarking some characteristics of the MOCAP data such as the physical feature of an articulated link model should be maintained. The requirement of imperceptibility in watermarking motion data is higher than in other watermarking applications such as images or video. For considering both the time varying and joints relations in motion, we adopted the singular value decomposition to resolve the multiple variables problem. In simulation results, some signal processing of motion data has been used to verify the robustness.

It is a big challenge to realize the dynamic selection and integration of the grid service component in the dynamic, cross-organizational grid environment. This paper introduces a dynamic-reconfigurable grid model (DRGM) with SOA. Reconfigurable idea is introduced to this model, and the implementation framework and method are proposed, so DRGM can support dynamic-reconfiguration at a lower level for grid application, then grid application can adjust its configurations dynamically to adapt to the grid environment with the dynamic selection of service component. Last the critical processes of the dynamic reconfiguration rules are written in ASM (abstract state machine). DRGM provides a new implementation approach for service-oriented dynamic reconfigurable grid application.
