When I was a student back in the 1960’s, the goal of particle and nuclear physicists was to seek the fundamental laws of nature, and one of the requirements of such a “fundamental” law was that it be renormalizable. Well now it’s 1996 and we’ve learned a few things in these three decades. One is that nonrenormalizable effective field theories can be just as if not more useful than their renorma...

Journal of the Society for Industrial and Applied Mathematics. In June of 1960 the paper was published: five pages under the rather unpretentious title "Polynomial Codes over Certain Finite Fields" [17]. This paper described a new class of error-correcting codes that are now called Reed-Solomon codes. In the decades since their discovery, Reed-Solomon codes have enjoyed countless applications, ...

T H E C O N C E P T of a closed ecologic .system in its entirety has existed for a number of years in the mind .of one of our foremost scientists in the field of Space Medicine. Dr. Hubertus Strughold had envisioned man on extended flights into space, his respiratory requirements to be met by an appa.ratt~s termed a photosynthetic gas exchanger. T,his brilliant idea began to assume its place in...

Full points may be obtained for correct answers to 8 questions. Each numbered question (which may have several parts) is worth the same number of points. All answers will be graded, but the score for the examination will be the sum of the scores of your best 8 solutions. Use separate answer sheets for each question. DO NOT PUT YOUR NAME ON YOUR ANSWER SHEETS. When you have finished, insert all ...

Common evaluations have grown to be a major component of all the ARPA Human Language Technology programs. In the written language community, the largest evaluation program has been the series of Message Understanding Conferences, which began in 1987 [2,3]. These evaluations have focussed on the task of analyzing text and automatically filling templates describing certain classes of events. Thes...
