In the Project of Osaka Institute of technology Electric-Rocket-Engine onboard Small Space Ship (PROITERES), a nano-satellite with electrothermal pulsed plasma thrusters (PPTs) was launched on September 9th, 2012. The main mission is to achieve powered flight of nano-satellite by an electric thruster and to observe Kansai district in Japan with a high-resolution camera. We developed Bread Board Model (BBM) and Engineering Model (EM) of the satellite, including electrothermal PPT system, high-resolution camera system, onboard computer system, communication system and ground station, electric power system, attitude control system etc, in 2007-2009. Finally, the development of the satellite Flight-Model (FM) was completely finished in 2010. In this paper, we introduce the feature of the satellite FM including EP system. Furthermore, the research and development of the 2nd and 3rd PROITERES satellites with electric thrusters are also introduced.

Rehabilitation assessment plays an important role in helping injured patients to recover quickly and smoothly. It is a cross-disciplinary field that involves many subjects including medical sciences, computer science, electrical engineering, robotics and so forth. Recently, many studies have been conducted in computer-assisted physical rehabilitation assessment, and motion capture techniques are increasingly used in this field. As such, the focus of this work is on computer-assisted hand rehabilitation assessment using an optical motion capture system. With the proposed scheme, we first capture the motion of a hand using the Vicon motion capture system and store the data in a file. Then, the file is read, visualized and manipulated in an application that we have developed. The application is able to analyze the dynamic range of motion (ROM) by computing the angles between geometric units formed by hand markers as specified by the user. According to our experiments, the application that we have developed measures ROMs with high accuracy for several key hand joints. In addition, the doctors and patients who have tried using our application feel that it is easy and intuitive to use and yields clear and accurate displays of the hand motion animation.

The development of computer network technology is exerting a significant impact on education which is also on a way to change, and new teaching models are being constructed. computer network provides technical support and broad development platform for E-learning, while E-learning teaching model is changing the traditional educational ideas and methods. In recent years, domestic universities initiate E-learning teaching mode, enforcing information construction of education. This paper will explore and analyze some related issues to E-learning in the environment of computer network technology.

This paper proposed a new architecture model of volatile data forensic. The model applied to all the volatile data sources is a general model. It can rebuild the evidence data fragment to chains of evidence which contains the behavior characteristics, so as to assist investigators to do case analysis. With the accumulated experience, the model can help judicial officers to intelligently analyze the same type of computer crimes, and based on currently available information to predict the impending crimes.
