The following are the APEC 2006 oral presentations. These papers were selected through a rigorous peer review process and are represented by papers in the APEC Proceedings. They were placed in an oral presentation because they generally have a broad appeal. Each digest was evaluated using an author-blind process by at least three members of the Program Committee, volunteers from all over the world with expertise in the area of the specific digest. Then, 25 members of the Program Committee met last September to consider digests individually and construct the conference program. Only 50% of the 570 submitted digests were selected for presentation in either the oral or dialogue sessions.
