9th International Workshop on the
Physics of Compressible
Turbulent Mixing
Cambridge, UK
19-23 July 2004

www.damtp.cam.ac.uk/iwpctm9/

 

 

 

Breaks and lunches

Tea/coffee will be served during breaks the poster rooms, and lunch will be served in Wolfson Court located adjacent to the main venue. The cost of lunch is included in the registration fee.

 

Oral presentations

Twenty minutes will be allotted for each oral presentation, with the anticipation of fifteen minutes talking, three minutes for questions, and two minutes for changeover. Audio visual aids include:

o Two overhead projectors

o Slide projector

o A data projector suitable for PC or Apple Mac

o A multi-standard (PAL/SECAM/NTSC) video player

o A PC with Power Point and Acrobat Reader installed

o A display of time remaining for the presentation.

 

Unfortunately, it is not possible to have a network connection in the auditorium.

 

Some additional poster boards will also be made available for oral presenters to display supplementary material in the poster rooms. Please let me know if you wish to make use of this.

 

Poster presentations

Posters will be displayed in two rooms adjacent to the main auditorium and will remain displayed for the entire week. There will be two formal poster sessions (one Monday and one Tuesday), each beginning with a session where authors can talk for two minutes (and present up to two overhead transparencies) to advertise their work.

 

The size of poster boards is 1.2m´1.0m (4¢´3¢). This is somewhat larger than A0 landscape. You are encouraged to use laptops to enhance your poster during the formal poster sessions, but the limited availability of power outlets in the room may mean that you need to run from batteries. We will have somewhat more poster boards than posters. Hence, if you wish more space, please let me know and I shall try to accommodate.

 

Discussion sessions

To reflect and enhance the scientific value of the Workshop, discussion sessions have been timetabled for the end of each half day. It is hoped that you will participate actively in these sessions which are intended to delve into any underlying themes of the papers (oral and poster) preceding them and to air (and hopefully help resolve) any contentious issues or novel ideas.
