Abstracts for posters should be the same as for individual papers and reports, but identified as poster proposals. Posters will be displayed in a viewing area. Presenters should be prepared to explain their work and answer questions about it. Posters may occupy 1-4 standard (8 ½ x 11 inches) sheets of paper, and may contain text and/or illustrations (tables, figures, and photos). Posters will be returned to their owners.
