Hey! We're Back!
It's been almost four weeks since the last NA Net Digest. The first
half of the delay was because we lost "Surfer", the venerable Sequent
computer that we've used ever since NA Net moved to Oak Ridge.
The second half of the delay was because I've been travelling to
a few places where I didn't have convenient net access.
We may have lost some of the submissions during this period. So, if you
sent something in over the last month that isn't including in today's
issue, please sent it again. Same address:
[email protected]
NA Net, and its close associate, Netlib, are now running on a couple of
Sun SPARCs that are either at Oak Ridge or the University of Tennessee --
I'm not sure which. I log in to a machine with an Oak Ridge address,
but most of the work is being done by a crew at the University.
Thanks to Keith Moore and the rest of the crew for getting things
working again.

Subject: Information on Numerical Methods for Porous Flow Needed
It has been a few years since I was last doing any work in numerically
modeling flow in porous media. When I last was exposed to it, the
standard finite difference techniques being used were truly horrible, very
diffusive first order upwind differencing techniques that smeared
concentration fronts and often lead to spurious results. I am again
working in the field and I am anxious to come up to speed on what the
state of the art methods are. From what I can see, the same old
bad techniques are still pretty widely used in the remediation and
petroleum communities, but I assume that there are other techniques out
there that are better and just haven't made it into general use yet.
So, with that little diatribe out of my system :-) , I would much
appreciate pointers to papers discussing modern numerical methods for
flow in porous media. My particular interest is multi-phase flow
of chemical groundwater contaminants. I am also very interested in
work that incorporates a pressure equation of state into the
description of the flow.
Many thanks!

Subject: Formulae Tables. (Bateman Manuscript Project)
Has anyone know whether if the book: "Higher Transcendental Function"
of Bateman Manuscript Project of CALTECH is still available from some
publisher today.
I found them (3 volumes of Higher Transcendental Function
and 2 volumes of the integral transformation) at my university library
of printed date in 1953 from McGraw-Hill. Are they out of print?
I would like to keep them for me at home.
( BTW. I wonder how much percentage the books covered the
Prof. Bateman's lifework collections? )
I wonder if the similar or larger formulae tables available by the
books or CD's, or netlib type file either Postscript or TeX style files.
I guess the copyright law prevents even the formulae tables stored by
the scanner or typed-in to re-distribute.
Thank you in advance.

Benin Conference on Scientific Computing, Nigeria
25-29 January 1994 is the date of the 6th Benin International Conference on
Scientific Computing held at the University in Benin City, Nigeria, under
the direction of Professor Simeon Fatunla, Head of Mathematics.
This has become one of the premier scientific events in West Africa, which
the Nigerian Federal Government supports financially and by sending
Ministerial representatives to the Strategic Symposia which take place
alongside the technical mathematical side. It is regularly attended by
visiting speakers from Europe, N. America, Japan and elsewhere in the world.
The main topics this time will include:
Ordinary and partial differential equations; DAEs; computational
fluid dynamics; continuous optimization; automatic differentiation;
mathematical packages and numerical software; software engineering;
large scale computing.
We invite people from academia and industry with interests in these areas
to participate. You will need to make your own arrangements for travel to
Lagos (currently a January 1994 London - Lagos return is available for #475
sterling or less). The conference sees to your reception at Lagos airport,
transport between Lagos and Benin, and accommodation in hotel or University
guesthouse.
Why go? Your expertise contributes to a forum where a growing number of
well-trained young Nigerian mathematicians and computer scientists make
international contacts, learn about new developments and present their work
which often applies numerical computation to Nigerian industrial or
governmental problems. The conference is also great fun and includes trips
to places of note, a theatre production and other social events. The past
few conferences have had speakers from Canada, China, Germany, Holland,
Japan, Spain, UK, Canada and USA among others.
Any enquiries please to Dr John Pryce, conference co-director,
Software Engineering Group, RMCS,
Shrivenham, Swindon, SN6 8LA.
(e-mail: [email protected]; e-mail on na-net: na.pryce),
Professor Bob Russell at Simon Fraser University (na.brussell), who was
there in 1992, can also answer your questions.

Subject: Invited Computer Science Professor Position in France
IMMEDIATE OPENING POSITION IN COMPUTER SCIENCE AT THE ENS LYON (FRANCE)
A one year position at professor level will be open at the Ecole Normale
Superieure de Lyon (ENS Lyon), starting in September or October 1993.
The ENS Lyon is one of the most famous high schools in France. It has
status very similar to that of a Scientific University. Disciplines
studied at the ENS Lyon are Mathematics, Computer Science, Physics,
Chemistry, Biology and Geology. ENS Lyon hosts research laboratories
covering all scientific disciplines taught to its students. Students
enter the school 2 or 3 years after the baccalaureat. The program of
2nd year corresponds thus to the 4th academic year.
The teaching activities consist of 2 courses per semester. Main domains
of expertise are operating systems, languages and databases. It will be
done within the "Departement d'Informatique et de Mathematiques (DMI)"
which involves about 20 full or part time faculty members. The DMI
offers programs in Mathematics and Computer Science designed for
undergraduate students in their 3rd and 4th academic year, severely
selected after a nation-wide examination (1000 candidates each year).
Approximately 50 students are annually in these programs (30 in
Mathematics, 20 in Computer Science). Introductory courses are also
given to students in other disciplines (Physics, Biology). Most of the
ENS Lyon students eventually end up with a PhD.
The research activities should be in relation with parallel languages
and systems. The researcher will be associated with research currently
done at LIP, the Computer Science Laboratory of the ENS Lyon. LIP
research activities are entirely devoted to the domain of parallelism
from models to architecture. With 60 researchers (20 permanent
researchers and 40 PhD students) and a laboratory equipped with
state-of-the-art parallel computing equipment, it is one of the most
advanced centers for research in parallel processing in Europe.
A minimum of a PhD degree with several years of teaching and research
experience is needed.
Salary corresponds to an assistant professor position: FF 16 000 - FF 20 000
per month, depending on the experience.
Lyon is a well known international city and a great place to live, nearby
the Alpes mountains.
If you are interested, please immediately send a mail and
confirm before July 5th 1993, by sending a detailed
resume via FAX & via E-Mail or cover letter.
