**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

**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.

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."

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.
