The AI'95 home page is: URL: http://www.cs.adfa.oz.au/ai95/ai95.html Notes ----- All {\em oral} presentations will have 25 minutes including question time. All {\em poster} presentations will get 3 minute oral presentation time to highlight their poster papers (no question time). Registration ------------ The registration room is SR101}. It is located on the ground floor in the North Lecture Theatres. Tea and Lunch Breaks -------------------- Morning and afternoon teas will be served in the undercrypt areas under the foyers. On Monday and Tuesday, we will use only the South foyer; on Wednesday through Friday, the Northwest foyer will also be available. Lunches will be served in the lower walkway between North and South lecture theatre blocks. Seating will be avilable in Room LT2, and in the marquee adjacent to lecture theatres South. Lunches may also be taken into the lunchtime panel sessions in LT1, but care would be appreciated. Local Information ----------------- Transportation Between ADFA and the City Shuttle buses will be available each morning and evening on 15-17 November 1995, transporting conference delegates between ADFA, Olims Hotel, and Macquarie Hotel. No buses will be available on 13-14 November 1995. However, cars with limited seats will be available for transporting delegates between ADFA and the two hotels. Please be prepared to wait if you want this service. Alternatively, you may use taxi or public transportation. Both hotels are fairly close to ADFA. One way taxi fare is under A\$10. The telephone number for taxi booking is 2859222. There is a public phone between the Computer Science building and the Library. Taxi usually picks you up from the ADFA roundabout. Bus Route 302 (weekday only) and 303 serve between ADFA and the city centre. The ADFA bus stop is next to the roundabout. About ADFA AI'95 will be held at the Australian Defence Force Academy (ADFA) in Canberra, the capital city of Australia. ADFA is located less than 5km from the CBD of Canberra. It is about 7 minutes drive from the city centre and 12 minutes drive from the airport. The University College within the ADFA is part of the University of New South Wales (UNSW). It is responsible for providing university education to officer undergraduates and officer cadets of the Australian Defence Force in addition to carrying out research and other university activities. The University College has an active postgraduate research programme in many disciplines, e.g., computer science, in which any people, either civilian or military, Australian or non-Australian, can be enrolled if they are considered qualified by the university. UNSW is one of the best universities in Australia. Some Useful Facilities at ADFA The area between Computer Science Building and the Library has a public phone, a bookshop, a coffee and sandwich shop, and a National Australia Bank ATM and office. Locations of Lecture Rooms LT6 and LT7 are on the top floor of Lecture Theatres North. LT5 and SR101 are on the mid floor of Lecture Theatres North. LT4 is on the bottom floor of Lecture Theatres North. LT1, LT2 and LT3 are on the top floor of Lecture Theatres South. TR1, TR2 and TR3 are on the bottom floor of Lecture Theatres South. 152 and 107 are on the mid floor of the Computer Science Building. PC, Mac and X-terminal labs for delegate use are available on the mid floor at the West end of the Computer Science Building. ------------------------------------------- 13/11/95 (Monday) Workshops and Tutorials ------------------------------------------- 09:00am -- 10:30am Workshop/Tutorial sessions 10:30am -- 11:00am Morning tea break 11:00am -- 12:00pm Workshop/Tutorial sessions 12:00pm -- 13:00pm Lunch break 13:00pm -- 15:15pm Workshop/Tutorial sessions (All tutorials start at 14:00pm.
