We are studying the following six areas related to computers and networks. Here, we briefly explain the outlines of our studies. Please refer our published papers and presentation materials.

1. Web Technology:
In this area, we study the advanced utilization technology of the fast-evolving World-Wide Web systems. Particularly, we are interested in collaborations of multimedia such as images and audios. Specifically, we have developed the panoramic image generation system from multiple cameras, the digital picture-show system, and the Web manual system using moving images and voices.

2. Educational Technology:
In this area, we study in the development and the management of the education support system "NOBASU (NetWork Based Assistant System for University education)" for our department. NOBASU is an WEB-based system that has been independently designed and coded by our group. Through this study, we aim the integration of "education" and "research" that are two missions in our university.

3. Optimization Algorithm:
In this area, we study heuristic algorithms for NP-complete or NP-hard combinatorial optimization problems. For example, as practical problems in our university, we have studied the English class scheduling problem, the laboratory assignment problem for undergraduate studies, and the student class placement in general educations.

4. Security:
In this area, we study the advancement and applications of the "group signature" as a digital signature to guarantee the anonymity of the signer. We have applied the group signature to the electric vote, the electric questionnaire, and the authentication of mobile users.

5. Computer Network:
In this area, we study the large-scale wireless network called the "WIMNET (Wireless Infrastructure Mesh NETwork)" as an inexpensive expansion of wireless access to the Internet, the optimal design of WDM optical networks for LAN and MAN, and the application-level multicast streaming system called "PeerStream" as an inexpensive system to deliver multimedia data to a large number of clients.

6. Open Source Software:
In this area, we study automatic manual generation systems for installing, operating, and managing open source softwares such as Linux, Apache, Xoops.
