If the results have been contributed to the public domain, could someone
post them to this newsgroup? I would guess that most subscribers would
be very interested in the results. (If not, would you email me a copy, too?)

Subject: Re: SIAM Membership List
Thanks to SIAM and the efforts of Eric Grosse, the SIAM membership list sits
in netlib. 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 <string>?" 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

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.

Subject: Report on a Conference in Nigeria
Conference in Computational Mathematics, Benin City, Nigeria,
Jan 25 - 29 1988, organized by Simeon Ola Fatunla of the
University of Benin.
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.

Subject: Motorola MC68881/MC68882 manual published by Prentice Hall
I just received a copy of this manual, copyright by Motorola but
published by Prentice Hall, so that, like the MC68020 manual,
it may actually be obtainable in technical bookstores rather
than by begging a Motorola sales office. 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.

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.

Subject: SIAM Annual Meeting in Minneapolis
SOCIETY FOR INDUSTRIAL AND APPLIED MATHEMATICS
MEETING ANNOUNCEMENT AND CALL FOR PAPERS
SIAM Annual Meeting and Short Course
Hyatt Regency Hotel, Minneapolis, Minnesota
July l0-l5, l988
DIRECTIONS IN APPLIED MATHEMATICS
Agenda for the Future
The organizers of the SIAM l988 Annual Meeting are planning a program
on evolving areas of applied mathematics and related topics that should
provide new opportunites for research and problem solving in the decade ahead.
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.
