Abstract
The fourth HPCD Workshop was held at Rutgers University on July 17 and 18, 1997, which was approximately the midpoint of the fourth year of the four year project. The workshop provided the opportunity to review the project goals, to bring together the people related to the project, summarize the experiences, and identify spinoffs and outgrowths of the HPCD effort. During the technical sessions of the workshop, investigators from each of the project's areas summarized the research that had been done in the project, concentrating on the previous year. This memo briefly outlines each talk and any ensuing discussion.
