Welcome to Lake Buena Vista, FL., USA

On behalf of the local organizing committee, I would like to welcome you to Lake Buena Vista, Florida, which is just outside Orlando, Florida. This year we have modified the organizational structure, combining efforts from Florida, California and Copenhagen. Hopefully these efforts have been successful. We have included all information pertaining to the conference in this program booklet. We also have provided a folder for your convenience. The meeting room will be arranged in a classroom style to facilitate taking notes. Coffee and tea will be arranged at the breaks. The secretariat outside the conference room will be available to assist you. Posters will be manned in the rear area adjacent to the auditorium.

The organizing committee has arranged an exciting program, which has been augmented by a large number of free talks and posters. A reception is arranged on Sunday evening at 7 PM at the Grosvenor Resort. I encourage you to participate in this reception so we can meet informally prior to the scientific program. Please wear your nametag to the reception, as well as the meetings to facilitate interactions. We have not set up meetings with dignitaries since we are in the premiere vacation resort in the U.S. and would like to allow you to partake in as many activities as possible. Please check with the hotel staff regarding transportation to major attractions. For those interested in nightlife activities, dinning, movies, and shopping you need only to walk across the street to Downtown Disney and Pleasure Island. You never know whom you will run into! On Wednesday evening we will have our annual dinner at the Grosvenor. If you have any dietary restrictions please let me know as soon as possible in order to accommodate your needs. On Friday we will have a bus tour of Kennedy SpaceCenter and spend a couple of hours visiting the visitors center at the Cape. Lunch will be at your own expense at the Visitors Center.

I hope you enjoy the meeting and as well as your visit to the Orlando area.

Michael J. Katovich

Invited papers:	20 min for presentation and 5 min for discussion.
Free papers:	10 min for presentation and 5 min for discussion.

The speaker is responsible for preparing slides and handing them in to the slide projectionist. Slide carousels will be available for each speaker. Speakers should load their own slides prior to the session and label the carousal. A viewing area will be made available to screen slides.

Poster Presentations

Since there will be a different set of posters each day, the presenter is requested to prepare the poster in the morning and take it down in the evening. The presenter is kindly required to be present at the poster as indicated in the program. The numbers on the poster boards correspond to the numbers indicated in this program. The poster size is 4 ft (120 cm) high and 4 ft (120 cm) wide. Posters are free standing and 4ft x 8 ft, thus there will be two presentations on each side of the board.
