Subject: Walking Through a Database of Algorithms for Appoximation

In na-digest/v88n40, Valeria Frontini writes

In response, I am pleased to announce a service to help locate
approximation software, in netlib or elsewhere.

First, say "dial 201-582-1238" or "telnet" and in
response to "login:" type "walk". (No password is required.)
The first of these connects you, via our uucp gateway, to a database
machine; the second connects you to the Vax750 which handles all
arpanet traffic for AT&T and which therefore can be painfully slow.

You will be presented with a menu like
1. form (basis of approximating space)
2. norm (criteria of approximation, figure of merit, nonstandard data)
3. variable (coordinate transform, mesh generation)
4. diagnostics
5. tools from other fields
6. omitted topics
and should respond with a digit to begin traversing the tree. At the
leaves you will find citations to published algorithms and available
software. Instead of a digit, type a ^ to back up one question, ^^ to
start afresh, or . or control-d to exit.

Comments are welcome, especially pointers to software that has been overlooked.

Subject: IEEE Digital Signal Processing Programs on IBM/PC

I am interested in knowing who has converted the IEEE
Digital Signal Processing Programs to be used on IBM/PC.
How much conversion is needed to run under the Microsoft
Fortran Compiler?

In particular, I am interested in getting hold of the code
for the Cepstral Analysis part for the moment.

Many Thanks. S.I. Chou 619-553-2541

Subject: Available Faculty Position at Chapel Hill


Available Faculty Position

The Department of Operations Research seeks candidates for a
tenure-track faculty position in Operations Research at the
assistant professor level. Preference will be given to
individuals with demonstrated interests in discrete optimization
and the analysis of algorithms. The department principally consists
of a graduate-level program offering masters and doctoral degrees in
Operations Research with 10 faculty, 25 students and an extremely
active program of basic research.

Minimally, a candidate should have a Ph.D. in Operations Research
or in a related field. Candidates are expected to have a strong
commitment to graduate level teaching and basic research. The
appointment will become effective on July 1, 1989. To receive
full consideration for this position, an application must be
received by January 9, 1989.

Please send a curriculum vitae and a list of four references.

Subject: Wilkinson Followship at Argonne National Laboratory

Mathematics and Computer Science Division
Argonne National Laboratory

Argonne National Laboratory is seeking outstanding
candidates in the general area of computational mathematics
to fill the newly created J.H. Wilkinson Fellowship in
Computational Mathematics.

This fellowship was created in memory of Dr. James
Hardy Wilkinson, F.R.S., who for many years had a close
association with the Mathematics and Computer Science
Division at Argonne, where he acted as a consultant and
guiding spirit for such efforts as the EISPACK and LINPACK

The J.H. Wilkinson Fellowship is intended to encourage
young scientists who are actively engaged in state-of-the-
art research in computational mathematics-including, but not
limited to, the development and implementation of numerical
algorithms for linear algebra. The candidate must have
earned (or be about to earn) a Ph.D. degree or the
equivalent during the past three years and should have a
strong background in numerical computation. The candidate
should also be interested in expanding into the area of
advanced computing research. Argonne's Mathematics and
Computer Science Division has strong programs in
computational mathematics and advanced computing, as well as
in software engineering and applied analysis.

This one-year appointment includes a competitive
salary, moving expenses, and a generous professional travel
allotment. Applications from qualified candidates, as well
as nominations for the position of Wilkinson Fellow, should
be addressed to Rosalie L. Bottino, Box D-MCS-WF89-83,
Employment and Placement, 9700 South Cass Ave., Argonne
National Laboratory, Argonne, Illinois 60439-4844.
Applications should include a resume and a statement of
research goals, and the names of three references. The
closing date for applications is December 1, 1988. The
applications will be reviewed during January 1989, by an
international selection committee. The position will
commence during 1989.

Further inquiries can be made by calling 312-972-7163
or by sending electronic mail to

Subject: Field Positions with Ardent Computer

At Ardent Computer we are looking to fill a couple of field technical
support positions. You would work out of one of our sales offices
(there are over a dozen, including three in Europe), and have a
range of technical responsibilities. You would report to the local
regional sales manager, but would have a lot of contact with our
Scientific Software group in the Sunnyvale headquarters. You would need
a strong background in scientific computing, especially Fortran, UNIX,
mathematics and graphics. An advanced degree and/or several years of
experience are desirable. Contact me and I will pass your name on to
the appropriate field office.
