Additional page charges by the journals are the responsibility of the authors. Excellent papers whose main authors are graduate students will be judged and selected by the Student Paper Award Subcommittee of the Program Committee for their scientific merits.Up to 5 best student papers may be selected for the ICCIS Student Paper Awards.
