Presentation facilities
Oral Presentations: Notebook PCs, data projectors, overhead projectors, screens and write-on boards will be available for the oral presentations. MS Office 2000 (Powerpoint) and Corel WordPerfect Office 2000 (Presentations) running under MS Windows 2000 / 98se will be available on the notebook PCs. It may be possible to make other software available on request. Owing to the somewhat isolated venue of the workshop, it may be difficult to correct problems at the workshop. Therefore I request that any speakers who intend to use an electronic presentation (eg. Powerpoint or Presentations) e-mail a copy of the presentation to me, Dave Liles ( dave.liles@up.ac.za ), a week or more before the workshop, so that I can ensure that the file is intact and runs properly with our equipment and software. Our mail system can handle files upto 8 to 9 Mb in size. If necessary, a compressed file (eg .zip) can be sent. I recommend that speakers do this, as a precaution against disaster, even if they intend bringing their own notebook PCs. Speakers should also bring a copy of the presentation with them on disk (eg CD-R or USB Flash Drive). I will e-mail a reminder of this to all speakers closer to the time.
Poster Presentations: Continuous wall space will be available for mounting posters, therefore there is no strict limits to the dimensions of the posters. The dimensions should, however, be kept within reasonable limits! (As a guide: ca 1 m wide by 1.5 - 1.7 m high.)
