This paper mainly analyzes the transmission line which is in series with compensation capacitor. For the compensation transmission line will contain rich transient components from low to high frequency when it occurs one phase ground fault. In this paper, we use the low-frequency resonance which generated by series capacitor and shunt inductor to determine the nature of the fault. First, the voltage will be filtered, extracts the low frequency components and integral it to calculating the low-frequency energy. Comparing the energy of arc to determine the nature of the fault, and then to judge whether bypass the series capacitor in order to prepare for recloure.

Currently the extensive application of embedded multimedia processing calls for requirement of hardware acceleration and multi-function expansion, it firmly requires an scalable and efficient design of system architecture for embedded multimedia processing terminal. At first, system architecture with distinct structures and reasonable modules is designed, a simplified multimedia framework is designed for embedded application, which includes a scheduler and a multimedia processing engine based on FFMPEG. The design of engine interfaces focuses on compatibility and scalability to deal with a variety of applied requirements. Then, embedded multimedia processing software is implemented based on the system architecture design. A scheduling program which schedules modules is implemented. A media player engine with scalable software interfaces is developed. Eventually, on Real 6410 platform, an embedded multimedia system is built, which makes use of LINUX Framebuffer device driver interface to display video and ALSA library to play audio for testing the system. The actual operation result proves that system architecture design simplifies the multimedia processing and supports multiple media formats as well as hardware acceleration. The scalability and efficiency make it suitable for embedded application.

Teenager's peer conflict has become an issue. Some negative personalities developed because of encountering peer pressure, conflict and frustration. These experiences lead to aggressive behaviors. Digital media is getting popular in teenager's life and this research try to design a special computer game that might influence teenager's improper behaviors. The experiment selects 180 high school students aged from 12 to 13 in 2 junior high school in central Taiwan. Participants will be assigned to play the specially designed computer game in which they can monitor the role in the games. Interaction between the participants and computer will be recorded over the course of the experiment for analysis. The goal of this research is to create an innovative and effective digital learning system in addition to traditional counseling method for teenager's peer conflict management.

The dynamic voltage restorer (DVR) is designed to protect sensitive loads from the effects of voltage sags on the distribution feeder. The capability of DVR in compensating long-duration voltage sags is largely depended on the amount of stored energy within the restorer which is very expensive. In order to reduce the price of DVR, many control strategies have been implemented to make better use of the stored energy. Unfortunately, the traditional voltage compensation strategies are merely designed to minimize the needed compensation voltage to extract more energy from the DC-link or to decrease the output active power of DVR or to reduce the distortions at the load. To combine the advantages and avoid the drawbacks of the traditional strategies, an optimized control strategy has been designed and tested by MATLAB simulation. The new strategy can dramatically increase the compensation time with low distortion at the load and without enlarging the energy storage of the DC-link
