**Subject: Norbert Wiener Prize Awarded to James Sethian**

The AMS/SIAM Nobert Weiner Prize in Applied Mathematics has been awarded

to James Sethian. Sethian is Professor of Mathematics at the University of

California at Berkeley, and Head of the Mathematics Department of the Lawrence

Berkeley National Laboratory. The AMS press announcement reads as follows:

January 8, 2004

PROVIDENCE, RI---James Sethian of the University of California, Berkeley,

is receiving the 2004 Norbert Wiener Prize in Applied Mathematics.

Presented every three years by the American Mathematical Society, the

Wiener Prize is awarded for outstanding contributions to applied

mathematics in the highest and broadest sense. The prize will be awarded

today at the Joint Mathematics Meetings in Phoenix, Arizona.

Sethian is being honored for his seminal work on the computer

representation of the motion of curves, surfaces, interfaces, and wave

fronts, and for his brilliant applications of mathematical and

computational ideas to problems in science and engineering. The prize

citation states: "A particularly noteworthy aspect of Sethian's work is

that he pursues his ideas from a first formulation of a mathematical model

all the way to concrete applications in national laboratory and industrial

settings; his algorithms are currently distributed in widely available

packages. Sethian's work is a shining example of what applied mathematics

can accomplish to benefit science as a whole."

**Subject: Olga Ladyzhenskaya**

I am sad to report the news of the death of Olga Ladyzhenskaya on

January 12. Although a giant of mathematics, she is not known as a

numerical analyst; however, she did provide the first (and still one of

the few) rigorous proofs of the convergence of a finite difference

method for the Navier-Stokes equations. More important, her seminal

work on partial differential equations had tremendous and lasting

influence on those who specialize in numerical PDEs. For example, she

is the "L" of the celebrated LBB condition that arises in mixed finite

element discretizations of the Stokes and Navier-Stokes equations.

Olga Ladyzhenskaya overcame great odds of a personal and political

nature to become one of the most influential mathematicians of her

generation. This gentlewoman will be very much missed by her family and

friends and by the scientific community.

**Subject: New Book, Numerical Computing with MATLAB**

I am very pleased to make this announcement to the NA Digest community.

"Numerical Computing with MATLAB" is a new textbook for an introductory

course in numerical methods, MATLAB, and technical computing. The emphasis

is on informed use of mathematical software. The topics include

Introduction to MATLAB

Linear equations

Interpolation

Zero finding

Least squares

Quadrature

Ordinary differential equations

Random numbers

Fourier analysis

Eigenvalues and singular values

Partial differential equations

George Forsythe initiated such a course at Stanford University in the late

1960s. Textbooks by Forsythe, Malcolm, and Moler, and Kahaner, Moler, and

Nash that evolved from the Stanford course were based upon libraries of

Fortran subroutines.

This textbook is based on MATLAB. A collection of over nearly 70 M-files

form an essential part of the book. Many of the over 200 exercises involve

modifying and extending the programs provided with the book. The book also

makes extensive use of computer graphics, including interactive graphical

expositions of numerical algorithms.

Two editions of the book are being published. An electronic edition published

by the MathWorks is available now on the Web. A traditional printed edition

published by SIAM, the Society for Industrial and Applied Mathematics, will

be available in the second quarter of 2004.

The URL for the electronic edition is:

**Subject: Software for Unconstrained Minimization without Derivatives**

Unconstrained Minimization without Derivatives

Recently, after about 2 years of development, I finished writing

some Fortran software for unconstrained minimization without derivatives.

I believe that most results of academic research should be available

free of charge, and I am delighted when my work is useful. Therefore

please let me know by e-mail if you would like to receive a copy of the

Fortran. My address is mjdp@cam.ac.uk.

The name of the software is NEWUOA (NEW Unconstrained Optimization

Algorithm). It is a development of UOBYQA (Math. Prog. B, Vol. 92, pp.

555-582, 2002), which is unsuitable for large n (the number of variables),

because the quadratic models of UOBYQA are constructed by interpolation

to (n+1)(n+2)/2 values of the objective function. On the other hand, the

number of interpolation conditions in NEWUOA is a parameter, the value

2n+1 being recommended, which reduces the magnitude of the routine work

of each iteration from n**4 to between n**2 and n**3. Thus NEWUOA has

solved problems successfully with up to 200 variables, which would be far

too onerous for UOBYQA. The freedom in each new quadratic model of NEWUOA

is taken up by minimizing the Frobenius norm of the change to the second

derivative matrix of the model.

No report is available yet that describes all the details of NEWUOA,

but I intend to write one in the next 6 months. The work has taken so

long, because rounding errors have caused severe loss of accuracy in an

updating calculation. I found an adequate cure to this damage last June,

which is presented in the report "On updating the inverse of a KKT matrix"

(Number DAMTP 2004/NA01, University of Cambridge). That report is on the

web at the address www.damtp.cam.ac.uk, where one clicks on Numerical

Analysis and then on Reports, because I do not yet have a proper home page

myself. I hope that the NEWUOA software will be helpful to many readers.

**Subject: Report on the SVG Meeting**

The SVG Meeting

The SVG meeting, a one and a half day workshop celebrating the 60th

birthdays of Jim Varah, Alan George, and Michael Saunders, was held at

Stanford University on January 9-10, 2004. The meeting featured

light-hearted talks in a festive atmosphere, combining scientific

computing and anecdotes from the honorees' past. Approximately 80

people attended the meeting, many of whom came from great distances.

Issues that were addressed at the meeting included the symmetrizability

of the 3-by-3 SVG matrix; the meaning of the acronym MXS; the EFGH

properties; the mysterious genealogical connection among Chebyshev,

Markov, and the honorees; the Matlab algorithm that was used to create

the meeting's mugs, courtesy of Cleve Moler; and many others. Iain Duff

mildly roasted the honorees in a banquet dinner speech. Showing his

hospitality, Gene Golub added two more to the uncountable number of

reception parties at his house. At the end of the meeting, the honorees

were given a chance to provide their rebuttals!

The program for the meeting and a collection of photos from the meeting

are now available at http://sccm.stanford.edu/svg.

The meeting was partially supported by a donation from FEMLAB.

Last Saturday I gave a short presentation on the (big) surprises you

may get when coding vector operations in C at the SVG meeting. (The

SVG meeting was organized by Gene Golub and colleagues to honor Mike

Saunders, Jim Varah and Alan George). I think that the material may

be of interest to many other people in this group. In particular I

would be happy to receive any explanation (even partial) to some of

the surprising results.

McDonnell Douglas Auditorium, Rm 100, Material Science Building

University of Alabama in Huntsville

Title: "Centroidal Voronoi tessellations: algorithms and applications"

Prof. Max Gunzburger

Department of Mathematics and CSIT

Florida State University

Abstract:

Centroidal Voronoi tessellations (CVTs) are special Voronoi diagrams

for which the generators of the diagrams are also the centers of mass

(with respect to a given density function) of the Voronoi cells. CVTs

have many uses and applications, several of which we discuss. These may

include data compression, image segmentation, clustering, cell biology,

territorial behavior of animals, resource allocation, grid generation

in volumes and on surfaces, meshless computing, hypercube sampling, and

reduced-order modeling. We then discuss deterministic and probabilistic

methods for determining CVTs, including some new probabilistic methods

that are amenable to parallel processing.

Bio: Prof. Max Gunzburger is the Francis Eppes Distinguished

Professor of Mathematics at Florida State University. Before moving to

Florida, he was Distinguished Professor of Mathematics and Chairman of

Department of Mathematics at Iowa State University (1986-2002). Prior

to that he was professor of Mathematics at Virginia Tech (1986-96),

Carnegie Mellon University (1981-89) and University of Tennessee

at Knoxville (1976-81).

Prof. Gunzburger obtained his Ph.D., M.S. and B.S from New York

University

and was a NRC post-doctoral Research Fellow at Naval Ordinance

Laboratory.

His specialties include numerical analysis, finite element methods,

mathematical modeling, partial differential equations, fluid

mechanics, flow control and superconductivity.

He is the editor-in-chief of SIAM Journal in Numerical Analysis.

**Subject: Workshop in Denmark on High Performance Computing**

CALL FOR PAPERS

PARA'04

WORKSHOP ON STATE-OF-THE-ART

IN SCIENTIFIC COMPUTING

June 20-23, 2004

http://imm.dtu.dk/~jw/para04/

ORGANIZERS:

Jack Dongarra, University of Tennessee and Oak Ridge Nat. Lab.

Kaj Madsen, Technical University of Denmark

Jerzy Wasniewski, Technical University of Denmark

DATES:

June 20, 2004: Two tutorials: Interval analysis and automatic

differentiation

June 21-23, 2004: PARA'04 Workshop sessions

PLACE: Technical University of Denmark, Lyngby, Denmark

SCOPE:

The emphasis of the PARA'04 meeting is shifted to High-Performance

Computing (HPC). The ongoing development of ever more advanced

computers provides the potential for solving increasingly difficult

computational problems. However, given the complexity of modern

computer architectures, the task of realizing this potential needs

careful attention. For example, the failure to exploit a computer's

memory hierarchy can degrade performance badly. A main concern of HPC

is the development of software that optimizes the performance of a

given computer.

The high cost of state-of-the-art computers can be prohibitive for

many workplaces, especially if there is only an occasional need for

them. A solution to this problem can be network computing, where

remote computing facilities are exploited via the INTERNET. Aspects of

network computing will be included in the PARA'04 Workshop.

CONTRIBUTED TALKS:

A limited number of contributed talks of no more than 20 minutes each

will be selected for the PARA'04 Workshop. Short abstracts of at most

one page should be submitted by January 31, 2004 to the address given

February 22-23, 2004

Department of Computer Science & Engineering

Indian Institute of Technology Delhi-110016, India

THEME

More generally e-Science refers to the development of the next generation

infrastructure to support computationally based science. This involves the

effective utilization of distributed computing, storage and networking

resources owned by different organizations but used by individuals both

within and outside these organizations. These resources are collectively

referred to as a Computational Grid.

e-Science envisages that large scale science will be increasingly carried out

in distributed global collaborations enabled by the Internet. A feature of

these collaborations is that they will require efficient access to very large

data collections and very large scale computing resources and will use

distributed visualization to support a high-level of user access.

SCOPE

The objective of this IFAC workshop is to bring together specialists

in the field of control of time-delay systems. High level contributions

on the many aspects of this research area, ranging from theory over

numerics to various applications, are awaited. Contributions on related

domains (e.g. control of uncertain systems, 2D and nD systems,

tele-operated control systems) will be considered with great interest,

provided they contain relations with time-delay systems.

In order to provide a joint forum for and create interaction between

specialists in control and numerical mathematics, and to increase

industrial participation, special attention will be paid to:

- numerical methods for time-delay systems

- applications, emphasizing delay effects in

telecommunication systems

**Subject: Conference in Tempe on Volterra and Delay Equations**

Second Announcement

The Third International Conference on The Numerical Solution

of Volterra and Delay Equations

May 18-21, 2004, Arizona State University, Tempe

This conference will be devoted to the computational and applied

aspects of Volterra and delay equations. These include functional

differential equations (delay, advanced and neutral), Volterra integral

equations, and Volterra integro-differential equations. There will be

both invited lectures and contributed talks at the meeting. In addition,

there will be ample time for informal discussions. Conference topics

include but are not limited to:

* Convergence and order properties of numerical methods

* Stability analysis and construction of highly stable methods

* Implementation aspects: software development and testing

* Applications of Volterra and delay equations

* Partial delay differential equations

* Numerical solution of stochastic delay differential equations

* Numerical solution of ordinary differential equations

The Conference is supported by the National Science Foundation and by

Arizona State University (Department of Mathematics, College of Liberal

Arts and Science, Office of the Vice-President for Research, and

Center for Systems Science and Engineering). Limited funds are available

for partial support of participants, in particular for students, junior

scientists, and members of groups which have traditionally been

underrepresented in the mathematical sciences. To apply for such assistance

please contact the conference organizers by March 1, 2004.

A special issue of Applied Numerical Mathematics will be devoted solely

to this Conference. This issue will be similar to Vol. 9, No. 3-5(1992)

of this journal that followed the First Conference and Vol. 24, No. 2-3

(1997) that followed the Second Conference (Volterra Centennial). Papers

for journal publication will be selected from among invited and contributed

papers and will meet the usual high refereeing standards of the journal.

The deadline for submitting the manuscripts is July 1, 2004.

The deadline for registration and receiving titles and abstracts is

March 31, 2004. The regular registration fee for the meeting is $80 and the

student registration is $40. Registration fee covers all social functions,

including the conference dinner.

Interested persons are requested to announce their intention to participate

and/or present contributed papers by contacting the organizers by e-mail,

**Subject: PhD Student Position at CWI, Amsterdam**

The research group "Nonlinear PDEs: Analysis and Scientific Computing" at

CWI, the Center for Mathematics and Computer Science in Amsterdam,

The Netherlands, offers a 4-year position for a PhD Student in

"NUMERICAL MATHEMATICS / SCIENTIFIC COMPUTING'

within the research project

"UNDERSTANDING THE 'ORGANIC CARBOM PUMP' IN MESO-SCALE OCEAN FLOWS"

which is funded by NWO (Netherlands Organization for Scientific Research)

through the Program "Computational Life Sciences".

The project consists of 3 PhD positions. The other two are at the Free

University Amsterdam (Prof. dr. S.A.L.M. Kooijman, Faculty of Earth and

Life Sciences), and at the University of Utrecht (Prof. dr. ir. H.A. Dijkstra,

IMAU, Physical Oceanography), respectively.

Research topic

The application field is the dynamics of phytoplankton in oceans. In particular,

the ability of phytoplankton to bind atmospheric carbon dioxide and transport

it into the deep oceans in the form of organic carbon, a phenomenon which is

termed the 'organic carbon pump'. This is of great interest for oceanography

and climate research, since it reduces the greenhouse effect on earth.

The project combines a biological model (Free University) with a high-resolution

ocean flow model (IMAU) and advanced numerical methods for calculating transport

of nutrients and biomass (CWI).

Profile

Successful candidates must have knowledge of the numerical analysis of PDEs.

The candidate that we are looking for is keen on working at the interface of

numerical analysis, bio-mathematical modelling and computational science, so

as to successfully co-operate with the other two PhD students.

A necessary condition for fulfilling the vacancy is a M.Sc. in (numerical)

mathematics, computational science, computational fluid dynamics, or a

comparable expertise.

Terms of employment

The salary with related employment conditions is according to regulations

for OIOs (Onderzoekers in Opleiding). Moreover CWI offers attractive working

conditions, including flexibility and help with housing for foreigners.

Application

You are invited to send an application, no later than February 20 2004, to

Dr. Ben Sommeijer

CWI/MAS,

P.O. Box 94079,

1090 GB Amsterdam,

the Netherlands,

E-mail: bsom@cwi.nl,

Your application should provide a description of your mathematical education,

your motivation for applying for this position, your CV, and examination marks.

Students who are about to finish their M.Sc thesis are also encouraged to apply.

For further information you can download the granted project description from
