Subject: Poisson/Helmholtz Equations in Cylindrical Geometry

Does anyone know of references concerning conjugate gradient (especially
good choices of a preconditioner) or multigrid methods for solving the
Poisson equation and the Helmholtz equation in three-dimensional
cylindrical domains?

The case that I am interested in is in which cylindrical coordinates are
used (r,theta,z) and in which the operators have been discretized with
2nd- or 4th-order accurate finite differences. The need to solve both
Poisson and Helmholtz equations arise when discretizing the Boussinesq
equations (Navier-Stokes plus heat diffusion) for three-dimensional
convection in an enclosed domain.

Thanks,
Henry

Subject: Calculation of Zeros of a High Order Filter

Does anyone know how to
1. calculate all the zeros of a 128-th order linear phase
FIR filter (128th order polynomial);
2. reconstruct the filter polynomial coefficients by all its
roots (128 in total),
without initial guess for each of zeros? By the 128th
order linear phase FIR filter, its zeros are all in reciprocal
conjugate groups (each group has 4 zeros: ri, 1/ri*, ri*, 1/ri)
for a real coefficient filter.

When use the function POLY and ROOTS in MATLAB, I got the problem of
error blow up, and I thought it's due to the algorithm problem when
used for a large number of roots or a higher-order polynomial.

Subject: Interpolation on Line-Curves

A smooth curve may be defined as the envelope of its tangents
(line-curve). Does anyone know of references where the corresponding
"interpolation" problem is treated? I am interested in
methods/algorithms and theory for constructing the curve when
only a finite number of tangents are given (the point of tangency
is NOT known). Thanks,

Subject: Analytical Algorithm for Determining Singularity

I'd appreciate a reference to an analytical algorithm (i.e., based on logical
operations or integer arithmetic) for determining singularity or
nonsingularity of an nxn matrix of non-negative integers. A few months ago I
found a trail of links in NA Digest to such a reference (I recall it led to
a "Chan's algorithm") but I have since lost that trail.

Subject: Query About Internships

Dear NA Digest Readers,

I am often asked about internship possibilities at The Boeing Company
for students in the math and computational sciences. Boeing has
such internships, (you can find out more about them at
http://www.boeing.com/employment/intern.html) but my intent here
is not to advertise this, but rather to find out what other companies
also provide such internships. If your company has an internship
program, where these types of students could participate, I would
appreciate finding out about it. If you would send me an email
with information, a URL or even just a "yes we do" that would be
very helpful.

Thanks

I have just finished a survey "Computation of Pseudospectra" for
Acta Numerica, written in a tutorial style around an extended
example of a non-normal differential operator. The article
contains a list of applications, many references, and a Matlab code.
Numerical analysts and graduate students who wish to read about
pseudospectra may find this a good place to start. The paper is

Subject: Poster Competition in Mathematics

UNESCO has defined the year 2000 as the year of mathematics.
There will be many activies under the heading

W M Y 2000

World Mathematical Year 2000. One of them is to rise public awareness by
having posters in public transport systems, e.g. Metro in Paris.

To make these Posters we need your ideas. The European Mathematical
Society, EMS, has opened a competition for this design. Since I am
convinced that also applied mathematicians can and should contribute I
submit this competition here.

WORLD MATHEMATICAL YEAR 2000
POSTER COMPETITION


Posters in subways,
math displays.
Says,
the EMS committee of WMY:
let a competition fly,
don't be shy
have a try,
why?
For the future of Mathematics!

As one of the events during the World Mathematical Year 2000, the European
Mathematical Society together with local committees in several countries
wishes to encourage the idea of posters with a mathematical theme to be
displayed in subways, and other public places.

These posters should catch the eye, and be representative of mathematics
and its uses.

The EMS is convinced that suitable posters will contribute to raising the
public awareness of mathematics.

The EMS committee of the WMY 2000 invites mathematicians to submit proposals
for posters, in the form of a sketch of the graphics and a suggestion for a
short text. There will be prizes for the three best proposals, respectively
200, 150 and 100 ECU, and the name of the proposer will appear on all those
posters which are eventually used.

Proposals should be sent before May 1, 1999, to the chairman of the EMS
committee for the WMY 2000: Professor Vagn Lundsgaard Hansen,
Department of Mathematics, Technical University of Denmark,
Building 303, DK-2800 Lyngby, Denmark.

CAMBRIDGE UNIVERSITY PRESS

Simultaneous publication in hard and soft cover as part of the
series Lezioni Lincee, Accademia Nazionale dei Lincei

The twin themes of computational complexity and information pervade
this book. The authors begin with an introduction to the computational
complexity of continuous mathematical models, that is, information-based
complexity. This is used to illustrate a variety of topics, including
breaking the curse of dimensionality, complexity of path integration,
solvability of ill-posed problems, the value of information in computation,
assigning values to mathematical hypotheses, and new, improved methods for
mathematical finance.

The style is informal, and the goals are exposition, insight and motivation.
A comprehensive bibliography is provided, to which readers are referred for
precise statements of results and their proofs. As the first introductory
book on the subject it will be invaluable to the many students and
researchers whose disciplines are influenced by the computational complexity
of continuous problems.

Subject: New Book, Multibody System Simulation

Reinhold von Schwerin "MultiBody System SIMulation - Numerical Methods,
Algorithms and Software"
Lecture Notes in Computational Science and Engineering Vol. 7,
Springer-Verlag, due May/June 1999
ISBN 3-540-65662-6 approx. XV, 280 pp DM 129,00

"The book presents innovative methods for the solution of multibody
descriptor models. It emphasizes the interdependence of modeling and
numerical solution of the arising system of differential-algebraic equations
(DAE). Here, it is shown that modifications of non-stiff ODE-solvers are
very effective for a large class of multibody systems. In particular,
implicit methods are found to dovetail optimally with the linearly implicit
structure of the model equations, allowing an inverse dynamics approach for
their solution. Furthermore, the book stresses the importance of software
development in scientific computing and thus presents a complete example of
an interdisciplinary problem solution for an important field of application
from technical mechanics."

Subject: Workshop in Honor of George K. Lea

A Workshop on the Evolution and Future
of Computational Engineering
In Honor of the Retirement of
George K. Lea
from the National Science Foundation
June 17-18, 1999
Washington, DC

A workshop in honor of the recent retirement of George K. Lea from the
National Science Foundation will be held at NSF headquarters in Arlington,
VA (metropolitan Washington) on June 17 and 18, 1999.

Computational Science & Engineering (CS&E) is now widely accepted as a
third modality for scientific investigation and engineering design, along
with theory and experiment. It is easy to forget that it was difficult to
find institutionalized support for research in CS&E until relatively
recently. George Lea's program in Computational Engineering at the
National Science Foundation has long been an exception, and upon his
retirement from the NSF it is both appropriate and timely to take
retrospective and prospective looks at the landscape of CS&E. George has
not only helped to define and promote the interdisciplinary content of
CS&E; he has also galvanized many interdisciplinary and
inter-institutional collaborations through his introductions of CS&E
researchers to each other at national conferences and at technical
gatherings of his own PIs.

Current and former PIs, colleagues, and friends of George and all who are
interested in tracing the past, present, and future of Computational
Engineering are therefore invited to a full day of technical presentations
and two surrounding evenings of social events at the workshop.

Details of the workshop are available at http://www.icase.edu/~keyes/gkl.
