Subject: Stochastic Parbolic Differential Equations

Hello na-netters,

I am a doctoral student wishing to pursue research in stochastic time
integrations. In particular, I am interested in solving nonlinear
parabolic (possibly vector) equations where the uncertainty sources are
mainly in the system parameters (for example, uncertain material
properties, uncertain geometry information etc.). I am interested in
physical systems that, in a deterministic world, could be efficiently
solved using methods like finite elements/differences/volume; just
for example, a few such situations would be nonlinear structural dynamics,
semi-conductor process and device modeling, oil reservoir simulations

My main goal is to look for an efficient computational (possibly
adaptive) procedure for which I can also estimate some accuracy/
convergence rates (possibly only numerically). I would be looking
at systems that at every time step cause a large (~of the order of
100K to 1000K) simultaneous system of equations (typ. non-symmetric) to
be solved (possibly using an iterative solver like GMRES).

I have done some literature search already and the effort is continuing.
If anyone out there has anything to offer that could help my search,
I would be most grateful to receive an e-mail back.

Thanking you in anticipation.

Subject: Integration Question

I would appreciate any suggestions on the following integral:

Integrate[( ((1-x)*(1-y))^(-1/2) ) / (x+y), {x,0,1}, {y,0,1}]

I am also interested in a related more general integral, but we can
take that discussion off-line. The answer will help in constructing
succinct parameterizations of Markov models. Our local expert on
hypergeometric functions was not successful, neither was Maple(V.2)
nor Mathematica(2.2).

New Book: Introduction to Scientific Computing: A Matrix-Vector Approach
Using Matlab.

Author: Charles F. Van Loan

Publisher: Prentice Hall, ISBN 0-13-125444-8 (Available Now)

Chapter 1. Power Tools of the Trade
Chapter 2. Polynomial Interpolation
Chapter 3. Piecewise Polynomial Interpolation
Chapter 4. Numerical Integration
Chapter 5. Matrix Computations
Chapter 6. Linear Systems
Chapter 7. The QR and Cholesky Factorizations
Chapter 8. Nonlinear Equations and Optimization
Chapter 9. The Initial Value Problem

Graphics and matrix-vector manipulation have been folded into
the discussion in a way that gets students to appreciate
the connection between continuous mathematics and computing.
Each of the nine chapters comes equipped with a theorem and a
collection of m-files designed to bolster intuition. Collectively,
the m-files communicate the key mathematical ideas and an
appreciation for the subtleties of numerical computing.

Subject: Parallelising Large Computational Mechanics Codes

Strategies and Tools for
Parallelising Large Computational Mechanics Codes
for Structural, Fluids, Electromagnetics and Multiphysics Analysis

11th - 12th November 1996
International Hotel, London

Prof Charbel Farhat, University of Boulder, Colorado, USA
Prof Mark Cross, University of Greenwich, UK
Prof Jochem Hauser, CLE, Salzgitter, Germany
Dr Roy Williams, California Institute of Technology, Pasadena, USA

This intensive short course is aimed at those involved in computational
modelling who wish to exploit the power of parallel processing in their
analysis. Although this is an advanced course it assumes no prior knowledge
of parallel programming; the course is self contained. The course, given by
leading authorities in computational modelling on large parallel machines
will cover a range of practical applications involving aerospace (including
CFD, elasticity) and materials/metals processing (including multiphysics
modelling). Some of the experience gained in the Europort projects will also
be discussed.

Subject: BLAS Technical Forum

BLAS TECHNICAL FORUM, November 7-8, 1996, Eagan, MN

We are planning a BLAS Technical Forum meeting on November 7-8.
The meeting will be hosted Michael Heroux and the meeting will
be held at Cray Research's facility in Eagan, MN:

Cray Research, Inc. -- A Silicon Graphics Company
655 Lone Oak Drive
Eagan, MN 55121

The Forum has been established to consider expanding the Basic Linear
Algebra Subprograms (BLAS) in a number of directions in the light of
modern software, language, and hardware developments. The first meeting
of the Forum was held in Nashville on February 19-20, 1996 and the next
meeting was in Atlanta on May 20-21, 1996.

Working groups have been established to consider the overall
functionality, a lightweight interface, and an object based interface,
for the BLAS. Other subgroups have also been established, either to
advise the current working groups or as placeholders for future working
groups on parallel processing issues, sparse operations, data structures,
extensions to the existing BLAS and language binding issues.

We strongly urge and encourage attendance at the meeting
so that we can make tangible progress towards much needed standards.
Wide input is needed to help ensure that emerging proposals are useful
and acceptable to the community.

It is appreciated that it is not easy for everyone to attend the
meetings of the Forum, but we would nevertheless welcome your input
since we wish the discussion to be as open as possible, and the results
to reflect consensus from the community at large.

A rough agenda for the meeting follows:
Extensions to existing
Language binding issues
Vendor comments and requirements
Applications comments and requirements
Users comments and requirements

Please send us items you would like to see on the agenda
or that you would like to discuss.

We will plan to start the meeting with lunch at 12:00 pm on Thursday,
November 7th and end by 4:00 on Friday, November 8th. Lunch is provided on
site both days.

Subject: Conference on Domain Decomposition

August 10 - 14, 1997
University of Colorado
Boulder, Colorado, USA

Domain decomposition (DD) is a very active research area of
computational mathematics and engineering, not only because
it is a scientific strategy suitable for high performance
computing, but also because it covers a broad class of
effective numerical methods for solving large-scale
mathematical-physical problems. This tenth meeting will occur
at a time of increasing interest in high performance
computational methods spurred by the availability of powerful
new parallel and distributed computing systems. Therefore,
its special focus will be on

High Performance Computing and Advanced Numerical Methods
for Industrial Applications.

The conference will include invited plenary talks by leading
experts in the field from academia, research institutions,
as well as industry, and parallel contributed and special
sessions. Contributions are sought on all aspects of DD-based
iterative as well as direct 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 discretizations
- DD methods for nonlinear and time dependent problems
- DD methods for eigenvalue problems

multi-material finite element formulation.

3. Fundamental issues in the transport of internal variables in
physically-based material models.

Applicants must have a strong background in computational mechanics

design tools for mixed digital/analog circuits packaging. Applicants should be
highly self-motivated and have demonstrated excellence in research.
The positions require strong experiences in some of the following areas:
numerical techniques for solving differential and integral equations,
especially in the area of computational electromagnetics;
electrical analysis of electronic packaging; development of computer
aided software tools. The positions is renewable up to three
years. Annual stipend is about $25k to $30k plus benefit. Applicants
should send by fax or e-mail a detailed curriculum vitae, selected
publications, and a list of three references to: Prof. Wei Cai, Department
of Mathematics, University of North Carolina at Charlotte, Charlotte, NC 28223.
Position will remain open until filled.
