Poster sessions are scheduled to provide an opportunity for selected papers to be presented in greater visual detail and should facilitate vivid discussions with attendees. For poster sessions, authors are provided with 100 cm x 200 cm bulletin boards on which to display their papers, along with a sign indicating their paper number. Presenters should display paper title, lists of authors and author affiliations on their posters. Authors must remain in the vicinity of their bulletin boards for the duration of the session (60-90 minutes) to answer questions. Note that poster presenters are not supplied with any audiovisual equipment.
