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.

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

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.

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
http://www.cwi.nl/projects/carbonpump (see also http://www.bio.vu.nl/thb/).
