Bracewell Date: Mon, 25 Jan 1993 11:54:00 -0800 (PST) Subject: Oscar Buneman Oscar Buneman, Professor Emeritus of Electrical Engineering, passed away peacefully in his sleep at his home on January 24, 1993. In recent years he worked regularly in his office, arriving from Los Altos Hills on his bicycle. Following a rigorous early education in the classical gymnasium in Hamburg and two years of university, he moved to Manchester where he completed a further five years of studies in mathematics. During World War II he worked on the magnetron with the British Admiralty, on the calutron in Berkeley, and on reactor research in Canada. For ten years he was a lecturer in mathematics at Cambridge University and a fellow of Peterhouse college, working in close contact with D.R. Hartree and P.A.M. Dirac who were principal influences in his development. As a visiting scientist at Stanford in 1957 he found the climate congenial and from 1960 has been a member of the Electrical Engineering department. As an emeritus, his door was always open and he was most generous with help to colleagues and students. Professor Buneman was a great outdoorsman and, with his wife Ruth, spent as much time in the mountains and sun as possible. Until Christmas he was a familiar sight in very brief shorts, a very deep tan and an ancient crash helmet, cruising across campus on his racing bike. He will be much missed by his colleagues. ------------------------------ From: Stephane Gerbi Date: Mon, 25 Jan 93 11:09:17 MET Subject: Nonliear Parabolic PDE Dear Na-netters I would like to know if it exists an efficient program (in Fortran if possible) or a numerical method easy to programm to solve a 1D fully nonlinear parabolic equation of the form: Ut = f(U, Ux, Uxx) in (O,L) + Neumann Boundary Conditions The function f is very smooth but the equation is degenerate i.e: it exists a time T0, and a point X0 where U tends to zero and Ut tends to infinity: the solution quenchs. I was thinking of finite differences + Newton method. I will appreciate any help Stephane GERBI Ecole Normale Superieure de Lyon Unite de Mathematiques Pures et Appliquees 46, Allee d'Italie 69364 Lyon Cedex 07 France e-mail: gerbi@umpa.ens-lyon.fr phone: +33 72.72.80.31 fax: +33 72.72.80.84 ------------------------------ From: Bob Fennell Date: 26 Jan 1993 21:04:42 -1812 Subject: Graduate Programs in Applied Mathematical Sciences Conference on Graduate Programs in the Applied Mathematical Sciences II April 16-18 , 1993 Clemson University Clemson, SC Current challenges for graduate education in classical analysis, computational and discrete mathematics, operations research and statistics will be discussed at this conference hosted by the Department of Mathematical Sciences at Clemson University. Specific conference objectives are to review the current status of graduate education in the applied mathematical sciences; to review the role of recent developments in the mathematical sciences in the solution of modern technological problems and the challenges and opportunities these developments present to graduate education; to obtain perspectives on current industrial/government employment opportunities and placement; and to publicize innovative graduate programs to the professional community. Participants will be selected to provide broad representation from all areas of the mathematical sciences, including individuals from academic, governmental and industrial institutions. The program will consist of a number of panel, audience, and group discussions. This format necessitates a limited number of participants. A conference proceedings will be published. Preliminary Program Friday April 16 Morning I. Graduate Mathematical Sciences Education: An Historical Perspective. II. Current Status of Applied Mathematical Sciences Graduate Education in the U.S. III. Challenges for Graduate Education in the Mathematical Sciences. Afternoon IV. Curricula for the 90's and Beyond. V. Curriculum Innovations. Saturday April 17 Morning VI. Computation in the Curriculum. VII. Employment Opportunities for the 90's. Afternoon VIII. Non-Academic Careers for MS and Ph.D. Students. XI. Group Discussions. 1. Recruiting and Advising Graduate Students. 2. Department Administration, University Support, Rewards. 3. Undergraduate Preparation. Sunday April 18 X. Summary and Closing Remarks. Invited participants include: John Burns, Don Bushaw, Ron Douglas, James Dyer, Bob Easterling, Avner Friedman, Carl Harris, Robert Hogg, Bill Lucas, Robert Lundegard, Tom Magnanti, Joyce McLaughlin, Anna Nagurney, Fred Roberts, Mary Wheeler, Doug Zahn. This conference is supported by a grant from the National Security Agency and additional funding from NSF is expected. For further information contact, R. E.

Any full-time student in good standing is eligible to receive an award. Top priority will be given to students presenting papers at the meetings, with second priority to students who are co-authors of papers to be presented at the meetings. Only students traveling more than 100 miles to the meetings are eligible for the awards. An application for atravel award should include: (1) a letter from the student stating the meeting for which support is being requested; (2) a letter from the student's adviser or department chair stating that the applicant is a full-time student in good standing; (3) if applicable, the titles of the papers to be presented (or co-authored) by the student at the meetings. Applications should be sent to the SIAM office (Attn: SIAM Student Travel Award), 3600 University City Science Center, Philadelphia, PA 19104-2688. Students may also apply by e-mail to siam@siam.org or by fax at 215-386-7999, but the letter from an adviser or department chair must be an original, sent by postal mail. Applications (including supporting letters) must be received at the SIAM office by no later than one month before the first day of the meeting for which support is requested. Winners will be notified by no later than two weeks before the first day of the meeting. Checks for the awards will be given to winning students when they register at the given mee ting. For further information about these awards, please contact Allison Bogardo or Donna DiLisi at the SIAM office.

A major aim of this project is to establish standards to enable efficient, and portable, implementations of iterative algorithms on high-performance computers. We envisage that a major benefit of this project will be a much quicker implementation of new algorithmic ideas into complex application packages. The first two reports in the SPARKER series are now available on anonymous ftp. These are SPARKER Working note 1 A proposal for user level sparse BLAS. I Duff, M Marrone, and G Radicati and SPARKER Working note 2 A proposal for a sparse BLAS toolkit. M Heroux We would very much welcome comments on these proposals from any readers of the digest. Information on how to obtain the papers is given below. Iain Duff (isd@directory.rl.ac.uk) Mike Heroux (mamh@cray.com) Michele Marrone (marrone@vnet.ibm.com) Giuseppe Radicati (radicati@vnet.ibm.com) To get SPARKER reports ftp 130.246.8.32 When prompted for a userid, reply with anonymous and give your email address as a password. Then cd to pub/open Set mode to binary Report 1 is in sparker.wn1.ps.Z Report 2 is in sparker.wn2.ps.Z ------------------------------ End of NA Digest ************************** -------
