CCMM95 SCHEDULE Below is a list of sessions, session times, and talks. Each speaker should plan for 20 minutes of lecture plus 10 minutes of questions and transition. The session chair will militantly enforce the schedule. Exact speaker times within each session will be set and posted the night before to account for no-shows. Morning sessions include one-half hour coffee breaks at 10:00 a.m. ************************************************************ You can access the papers and abstracts on MGNet. Authors can submit papers to the MGNet.
