Subject: Wilkinson Prize to Chris Bischof and Alan Carle

The 1995 Wilkinson Prize for Numerical Software has been awarded to
Chris Bischof and Alan Carle for ADIFOR 2.
The award presentation took place July 3 at the International Conference
in Industrial and Applied Mathematics (ICIAM 95) in Hamburg.

ADIFOR, which stands for the automatic differentiation of Fortran,
is a system for the computation of derivatives of functions defined
by Fortran 77 programs. The ADIFOR project was started in 1991,
in collaboration with Andreas Griewank and George Corliss.
The present version of the system, ADIFOR 2, provides a new level of
ease of use, flexibility, and computational capability. ADIFOR 2
supports all features of Fortran 77, including complex arithmetic.
ADIFOR 2 was cited as being a significant advance on the state-of-the-art
in numerical software.

The Wilkinson Prize is awarded in honor of the outstanding contributions
of James Hardy Wilkinson to the field of numerical software.
The award is presented to the entry that best addresses all phases of the
preparation of high quality numerical software. The prize is sponsored
by Argonne National Laboratory, The National Physical Laboratory and the
Numerical Algorithms Group.

The 1999 Wilkinson prize will be awarded at ICIAM in Edinburgh.

Continuing Fatunla's work in Nigeria

Following Prof Simeon Fatunla's death in a car accident reported in
na-digest in May, a large number of messages of support came in from all
over the world leaving no doubt of the regard in which Fatunla's tireless
work was held by many colleagues in the computational mathematics

A 'committee of friends' has been formed to support the continuation of his
work developing computational and industrial mathematics at the University
of Benin and elsewhere in Nigeria. The group comprises four UK attenders at
the 1994 conference:
Dr Marco Marletta, Univ Leicester
Dr Chris Phillips, Univ Newcastle upon Tyne
Dr John Pryce, Royal Military College of Science, Shrivenham (chair)
Prof Alastair Spence, Univ Bath
together with
Prof Rolf Jeltsch (Zurich, Switzerland)
Prof Bob Russell (Simon Fraser, Canada)
as representatives for Europe and N. America, and
Prof S. Ahonkhai, Head of Chemistry
Prof A. Odebunmi, Head of Psychology
Prof E.A.C. Nwanze, Dean of Science
as local coordinators at University of Benin.

Arrangements are in hand for a Workshop Jan/Feb 1996 at both Uniben and the
National Mathematical Centre (NMC) on the lines of that run at NMC early
this year by Rolf Jeltsch.

John Pryce and his Nigerian wife Kate went over for the funeral ceremonies
15-17 June. Amidst the grief (some 2000 people attended a moving
Commendation Service in the main university auditorium on 16 June) there
was no doubt about the commitment of his colleagues to continue his work.
The presence of an overseas colleague was clearly a great encouragement.

Subject: Graduate and Professional Resources on the WWW

We are looking for WWW resources about grad school and other professional
opportunities for young mathematicians and would like to include a list of
these resources on SIAM's undergraduate WWW pages. If you know the address
of anything that might be of interest to students preparing to graduate next
spring, could you please send them to us at The
list will be kept on the SIAM undergraduate pages, located at

Also, if you would like to share any experiences or advice for young
mathematicians, please see our essay and opinion section on how to do

Subject: E-mail List and FTP Site for Fractional Transforms

Dear Colleague,

In contacts with some colleagues, the idea of creating a mailing list related
to fractional transforms (the fractional Fourier transform and other
fractional transforms) was raised. This message is to announce the creation of
such a mailing list.

The list will be physically located at INESC (Instituto de Engenharia de
Sistemas e Computadores - systems and computer engineering institute, Lisbon,

To request to be included in the list, please send an e-mail message to
"", indicating your name, e-mail address, regular-mail
address and the reasons for your interest to be included. I will send you, as
soon as possible, a confirmation message, with instructions for using the list.

In principle, only people who actively work on or with fractional transforms
and related techniques (e.g. time-frequency analysis) will be accepted in the
list. This is a normal policy in this kind of lists. Its intended to avoid
having a lot of messages like "can you explain what are fractional

The list will be administrated by myself, for the time being (see my
coordinates below). The list will be unmoderated, meaning that messages
sent to the list will be immediately distributed to everyone, without any
filtering. Moderation of the list is not envisaged unless the kind of traffic
appearing in the list shows moderation to be absolutely necessary -
something that I wouldn't expect to happen for a long time.

An ftp-accessible archive has been created at INESC (Instituto de Engenharia
de Sistemas e Computadores - systems and computer engineering institute,
Lisbon, Portugal), for acting as a repository of articles, technical reports
and other manuscripts on fractional transforms (both the fractional Fourier
transform and other fractional transforms).

The ftp site's address is "", and the directory is
If you wish to use this repository, please first download and read the file
00README.TXT. This file contains instructions for downloading and uploading
files. For the time being, this repository only contains the readme file,
the "" file, and an index. But feel free to upload your papers. The
users are who make such a service useful.

Please feel free to forward this announcement to others.

Yours sincerely,
Luis B. Almeida

Subject: Conference on Domain Decomposition Methods


When: 3rd - 8th June 1996
Where: By the Hardanger Fjord, near Bergen, NORWAY.


Domain Decomposition (DD) has received significant attention in scientific
and engineering computing because it is not only a computing strategy suitable
to high performance computing systems, but also refers to a broad class
of effective numerical methods for solving large scale mathematical-
physical problems from sciences and engineering. The conference will feature
invited lectures, selected contributed papers, and poster presentations.

We invite contributions on all aspects of DD-methods, including numerical
analysis of DD methods, block and substructuring methods, multigrid and
multilevel methods, fictitious domain methods, DD methods for high order
and spectral methods, DD methods for nonlinear and time dependent problems,
DD methods in computational fluid dynamics and structural mechanics,
graph decomposition, general iterative and preconditioning methods,
strategies and technologies of high performance computing, parallel
implementations, software developments, and industrial applications.

Abstracts: 26. January 1996 (1 page abstract)

The conference is organized by the University of Bergen.

Subject: PhD Studentship at University of Manchester

PhD Studentship at UMIST:

I have a PhD studentship, funded by EPSRC, to offer to someone
interested in working on a problem of propagating fluid dynamical
boundaries (as are found in flames or some phase transitions).
The project title is:

"Evolution Equation for a Flame-Front with Memory"

The studentship is to be held in the mathematics department at
UMIST, beginning in September or October 1995 and is only open
to those considered eligible for EPSRC studentships. That is,
EPSRC must approve any candidate for the studentship and this may
mean that the candidate would need to be British (in some sense).

The EPSRC have given me very little notice of this studentship
and I must find a suitable candidate by about the end of July.
If you are interested, please let me know as quickly as possible
sending me relevant details about yourself. My current address
and other co-ordinates are as follows:
