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.

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. ------------------------------ From: Kelly Black Date: Mon, 10 Jul 1995 08:44:34 -0400 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 siamug@spicerack.unh.edu. The list will be kept on the SIAM undergraduate pages, located at http://www.math.unh.edu/~siamug. 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 so.

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, Portugal). To request to be included in the list, please send an e-mail message to "frt-request@inesc.pt", 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 transforms?". 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 "aleph.inesc.pt", and the directory is "/pub/frt-prose". 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 "test.ps" 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.

Summary: 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.

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: Dr. J. W.
