When submitting your abstract, please indicate the type of presentation for which you would like to be considered. A limited number of papers will be selected for 30-minute talks, but all others will be considered for 20-minute lectures or poster formats. The poster sessions will be organized by themes to enhance interaction between presenters and attendees. If you wish to be considered for a 30-minute presentation, we ask that, in addition to the 100 word abstract submitted on a SIAM abstract form, you should also submit a 750 word abstract typed on plain white bond paper.
