8th Meeting of the ITPA Confinement Database & Modeling Topical Group
18-21 April, 2005
Kyoto UniversityKyoto, Japan
Version r5, 18 April
General Scheduling Information (A. Fukuyama) and Guidelines for Session Chairs (V.
Mukhovatov)
1. One large conference room (for combined session) and four smaller meeting rooms (onefor TP, one for PE and two for CDBM) are available.
2. Since the rooms are closed until 9:00 am, the session should start at 9:30 am on the firstday (4/18) and at 9:15 on the following days.
3. The lunch time, 12:30-14:00 or 13:00-14:00, is recommended because the university
cafeteria is very crowded until 13:00 especially in April, the beginning of a new academicyear.
4. The meeting rooms are available until 19:00 on the first three days and 13:00 onThursday. If you would like to have a session on Thursday afternoon, I will arrange aroom somewhere.
5. Each room has a PC projector and a screen. The number of over-head projector is very
limited. Please recommend electronic presentation to the participants.
6. The information on internet access was added on the web page:
http://bpsi.nucleng.kyoto-u.ac.jp/itpa2005/
7. Guidelines for collection of electronic talk copies and generation of session summaries by
Session Chairs:(1) Session Chairs are nominated before the Meeting and indicated on agendas.
(2) Each speaker is requested to present to the Session Chairman, before or during theMeeting, a Concise Summary of his/her talk (~1/3 page, preferably in .doc format),in addition to an electronic copy of his/her presentation. Electronic copies of talks
will also be collected at the meeting by U. Kyoto staff for distribution via web site.
(3) Each Session Chair should prepare a summary of his/her Session based on thecontents of presentations, summaries of individual talks, and discussions during theSession, and sends it (electronically) to Chair and Cochair of the Group during theMeeting or within 1-2 days after the Meeting.
(4) The Chair and Cochair of the Group will prepare the Executive Summary of theMeeting by May 2 and the Minutes of the Meeting shortly thereafter.
