It discusses the structure and orientation osome selected foreign programs as they challenge traditional U.S. 'market leadership in some areas of computers and communications. Fihally, it examines a set of issues that were raised in the course ok the study: manpower, institutional change, the new research organizations that grew out of Bell Laboratories, and the implications of trends in overall science and technology policy.

Breuker, J.W.H.M. Uiterwijk ∗, H.J. van den Herik Department of Computer Science, MATRIKS Research Institute, Universiteit Maastricht, P.O. Box 616, 6200 MD Maastricht, Netherlands Received May 1998; revised October 1998 Communicated by A.S. Fraenkel Abstract So far the game of Domineering has mainly been investigated by combinatorial-games re- searchers. Yet, it is a genuine two-player zero-sum game with perfect information, of which the general formulation is a topic of AI research. In that domain, many techniques have been developed for two-person games, especially for chess. In this article we show that one such technique, i.e., transposition tables, is ÿt for solving standard Domineering (i.e., on an 8×8 board). The game turns out to be a win for the player ÿrst to move. This result coincides with a result obtained independently by Morita Kazuro. Moreover, the technique of transposition tables is also applied to di erently sized m × n boards, m ranging from 2 to 8, and n from m to 9. The results are given in tabular form. Finally, some conclusions on replacement schemes are drawn. In an appendix an analysis of four tournament games is provided. c 2000 Published by Elsevier Science B.V. All rights reserved.

THE HENRY FORD COLLECTING INNOVATION TODAY TRANSCRIPT OF A VIDEO ORAL HISTORY INTERVIEW WITH CHARLES ELACHI FEBRUARY 24, 2009 JET PROPULSION LABORATY PASADENA, CA ©THE HENRY FORD 2009 INTERVIEWER: BARRY HURD PRODUCER: JUDITH E. ENDELMAN 2 3 01 ELACHI A HISTORY OF THE JET PROPULSION LABORATORY BARRY HURD: 01:00:49;01 I'll tell you what, just tell us, lotta people don't know, tell us where we are, and what goes on here, maybe a little history of JPL. CHARLES ELACHI: 01:00:54;11 Okay, yeah. This place started in the 1930s. And it's like any kind of very innovative place, started by small group of people. And they were couple of students at Cal Tech, at the California Institute of Technology, a small private university in Pasadena working with a professor called von Karman. And they were to learn about rockets. 01:01:14;17 And the way they tried to learn about rockets is mix different chemical and see which one blows up, anymore, I mean, that's how you start doing work in the lab. And the campus got very nervous about them blowing up a building. Matter of fact, they did blow up a shack, you know, on the campus. So they were told, "Why don't you 4 go to Arroyo where there is nobody there, and try your chemistry?" And that's how JPL started. 01:01:33;26 So we are the group of four students and a professor, came to Arroyo here, and they were just mixing chemicals, and see which one works better, and then they got a little bit better at it, and then a little bit better at it.
