Time Allowed for Each Presentation
The conference organizers expect every speaker of a scheduled presentation to register and attend the conference. If it becomes necessary for a speaker to cancel the presentation, the speaker is expected to find an alternate presenter immediately, preferably one of the speaker's coauthors. The speaker must inform the SIAM Conference Department (firstname.lastname@example.org) immediately of any changes to his/her scheduled presentation.
A "no-show" or canceled presentation can cause serious inconvenience to the attendees and conference organizers.
