This means that you are able to get the address of any individual who belongs to SIAM by sending a msg to netlib. The msg should read "Whois ?" Of course, the use of this information should be for personal use and NOT for making extensive distribution lists. Try your own name (if you are a member of SIAM --- and if you aren't, you might consider joining). -- Gene ------------------------ >From: Art Werschulz Date: Thu, 4 Feb 88 09:25:58 EST Subject: Re: Numerical Software Tools in C Awhile back, somebody (whether on this mailing list or on the USEnet news group sci.math.num-analysis, I don't remember which) asked for a book on C for numerical analysts (rather than systems hacker types). The following book fits the description: "Numerical Software Tools in C" by James Kempf, Prentice-Hall 1987 ISBN 0-13-627274-6 Enjoy.

I hesitated quite a lot before accepting the invitation to this conference. Many more or less bad stories about Nigeria had been brought to my attention. Today I just wanted to tell everybody the extremely good experience we had. From outside of Africa the following people attended the conference: G. Corliss, Guo Ben-Yu, G. Hall, P. Kaps, J. D. Lambert, R. Mattheij, J.D. Pryce, J.N. Sanz-Serna, A. Shidfar and myself. The Nigerian people took extremely good care of us, were very helpfull and made our stay a very pleasant one. The moment we passed the passport control at Lagos International Airport, we were met by a university official who helped us to make the connections to the continuation flight to Benin City, or we could have been driven directly to Benin City. In Benin City again S. Fatunla and his staff cared for us the whole time until we were finally seen off at Lagos International Airport. Professional problems which our collegues in Nigeria have to face are huge -- like no journals since 1981, power breakdowns approximately once a day (the computer centre has a whole room of batteries to keep the current steady), poor communications and so on. One can not help but admire the way our collegues fight against all these circumstances. This message is just to ask everybody to help our collegues in Nigeria whenever possible. Prof. J.O. C. Ezeilo of the University of Nsukka, Nigeria, (President of the Nigerian Mathematical Society) is building up a Mathematics Center funded by the federal Governement. He is looking for possible cooperation with the mathematicians from outside Nigeria. If anybody wants to get futher information please let me know or contact one of the above mentioned participants.

At last there will be an answer for people that I've told to read a 68881 manual without telling them how to obtain it. The MC68881 is the best hardware implementation of IEEE arithmetic from the standpoint of completeness and correctness, except for some minor complaints: transcendental functions are not monotonic in extended precision, log2(x) and 2**x aren't exact in some places they could be, there are no fmove-out instructions that round the source f register to the stored value not all the information that a user trap handler could exploit is available in user mode Transcendental functions are guided by the spirit rather than the specification of the IEEE standard, anyway, and most other hardware implementations don't come close. CISC enthusiasts should compare the 68881/2 instruction set to anything similar they may have been using to see the difference a clean orthogonal instruction set can make. RISC enthusiasts don't care about on-board transcendentals because, by their own admission, they are smart enough to code them faster using a smaller instruction set. They would be well advised, in general, not to be too pleased with their results until they are reasonably close to the 68881's in accuracy. I don't know whether or not to be surprised, but the page layout produced by Prentice Hall is not as aesthetically pleasing as that of the 68881 manual published by Motorola. ------------------------ >From: Rolf Jeltsch Date: Thu, 04 Feb 88 13:49:15 CET Subject: International Conference on Hyperbolic Problems Hyperbolic Problems, Theory, Numerical Methods and Applications - Second International Conference, RWTH Aachen, March, 14-18, 1988 Objective The first international conference on Hyperbolic Problems was held in St. Etienne, in 1986. The proceedings were published in the series: Lecture Notes in Mathematics (Springer, Heidelberg 1987). Systems of nonlinear hyperbolic problems play an important role in science and technology, e.g. aerodynamics, multiphasic flows with cavitation, nonlinear waves in solids, flow in porous media, plasma physics, astrophysics, combustion problems, non- equilibrium flows, extraction, biology. Significant advances made in the last few years will be presented in 20 plenary sessions and in 97 contributions. The main topics are: 1. Theory of nonlinear hyperbolic systems 2. Numerical methods for solving these systems 3. Applications. Scientific Committee Y. Zhu, Academia Sinica, Beijing Z. Wesolowski, Polish Academy of Sciences C. Weiland, MBB, Munich P.

Prizes to be awarded at the l988 SIAM Annual Meeting: The George B. Dantzig Prize The prize is awarded jointly by the Mathematical Programming Society (MPS) and SIAM. It is awarded for original work which by its breadth and scope constitutes an outstanding contribution to the field of mathematical programming. The Dantzig Prize is awarded every three years and, while normally presented at the International Symposium of MPS, it will be awarded for the first time at this SIAM meeting. The Richard C. DiPrima Prize The Richard C. DiPrima Prize was established in l986 to commerorate the former president of SIAM who also served for many years as a member of the SIAM Council and Board of Trustees, as Vice President for Programs, and as a dedicated and committed member. The prize is awarded to a young scientist who has done outstanding research in applied mathematics and who has completed his/her doctoral dissertation and completed all other requirements for his/her doctorate during the period running from three years prior to the award date to one year prior to the award date. This will be the first awarding of this prize which is scheduled to be given every even year. The John von Neumann Lecture and Prize The lecturer will survey and evaluate a significant and useful contribution to mathematics and its applications. The prize may be awarded to a mathematician or to a scientist in another field but, in either case, the recipient should be one who has made distinguished contriubtions to pure and /or applied mathematics.
