Subject: Error Estimator for Diffusion-reaction Equation

I am considering a simple (stationary) diffusion-reaction equation of the type

- epsilon * Laplace(u) + u = f in Omega
u = 0 on Gamma

I am looking for a-posteriori error estimators where the error is measured
in the energy norm. Especially I am interested in estimators which are
uniform with respect to the small parameter epsilon (1E-3 .. 1E-7).

Were such estimators already derived (and if 'yes', how do they look like
and where are they published)? I would very much appreciate any help that
you could give.

Numerical Methods For Singular Perturbation Problems - Error Estimates
in the Maximum Norm for Linear Problems in One and Two Dimensions

by J J H Miller (Trinity College, Ireland), E O'Riordan (Dublin City Univ.,
Ireland) & G I Shishkin (Russian Acad. of Sci., Russia)

This book introduces the reader to fitted numerical methods for solving
singularly perturbed differential equations. The performance of fitted
methods is not adversely affected by the value of the perturbation
parameter. The book concentrates on fitted mesh methods. These methods focus
on the appropriate distribution of the mesh points for singularly perturbed
problems. The fitted mesh algorithm is particularly simple to implement in
practice, but the theory of why these methods work is far from simple. This
book introduces the reader to the theory behind these novel numerical

in Wuppertal 1995.
This volume contains contributions from outstanding research specialists
based on their presentations at SCAN-95. It covers all aspects of scientific
computing with validation, starting with the latest developments in the
design of floating point units together with algorithms for floating point
operations and elementary function evaluations with maximum accuracy. The
book continues by treating scientific computing methods for many areas of
applied mathematics such as numerical linear algebra, nonlinear equations,
global optimization, ordinary and partial differential equations and
dynamical systems. Some computer science aspects like complexity are also
considered as are examples where validation methods have successfully been
used in applications from the engineering sciences.

Subject: Computational Fluid Dynamics Workshop

Workshop Announcement

The Institute for Computer Applications in Science and Engineering
(ICASE) and NASA Langley Research Center (LaRC) will conduct a Workshop
on "Barriers and Challenges in Computational Fluid Dynamics" at the
Holiday Inn- Hampton Coliseuum Hotel and Conference Center, Hampton,
Virginia on August 5-7, 1996.

As a new millennium approaches, Computational Fluid Dynamics (CFD) is
undergoing an important transition. CFD is playing an integral role in
many interdisciplinary applications. In addition, CFD techniques are
increasingly being used in nontraditional areas such as material
sciences, manufacturing technologies, and others. At this time, it is
particularly important to take an inward look and catalog the
challenges that face the field and identify the barriers to be
overcome. Numerical uncertainties need to be categorized and quantified
so that they are not carried over to the new fields where we do not
have years of experience to help us separate numerical uncertainties
from physical uncertainties. In addition, techniques deemed
inappropriate in CFD may well be the methods of choice when applied to
new disciplines.

The workshop is intended for scientists, engineers, mathematicians, and
other interested individuals from industry and academia.

Key note lectures will be given by:

Michael Giles, Oxford University
"Progress in Applied Numerical Analysis"

Alexandre Chorin, University of California, Berkeley
"Numerical Evaluation of Partition Functions in Turbulence
Theory and in Solid State Physics"

Stanley Osher, University of California, Los Angeles
"Subscale Capturing"

Philip Roe, University of Michigan
"Compounded of Many Simples: Reflections on the Adequacy
of Model Problems in CFD"

Subject: Computer-Aided Molecular Design Workshop

Cornell Theory Center

Introduction to Computer-aided
Molecular Design Workshop

July 10-13, 1996
Cornell University, Ithaca, NY

This workshop provides a broad introduction to computer-aided molecular
design. We will describe how computational methods can be appropriately
applied to real-world problems in the pharmaceutical, biotechnology, and
chemical industries. A variety of methods will be discussed, ranging from
statistical methods based on experimental data to high-level ab initio
quantum chemical calculations. The methods to be introduced include
molecular dynamics, quantum chemistry, and dielectric-continuum solvent
models. Sections of the workshop will also introduce homology-based protein
modeling and general-purpose optimization methods used across a range of
computational chemistry methods.

The workshop will combine descriptions of methods with applications to
specific areas. Applications will include predictions of physical
properties of molecules (solubilities, conformations, pKas, diffusion
coefficients, etc.) and predictions of binding properties of drugs (binding
geometries and energetics). After each method is introduced, it will be
illustrated with a case study. The material in the lectures will be
reinforced through hands-on computer laboratory sessions, which will
include both introductory software tutorials and more extensive
"mini-research projects" using the computer resources at the Cornell Theory


Dr. Michael Colvin
Senior member of the technical staff at Sandia National Laboratories, in
Livermore, CA. Colvin's main research interest is the application of
quantum chemical methods to understand biochemical processes. The nature of
these research problems has involved him in more than a decade of research
on quantum chemical methods for massively parallel computers and the
development of methods for accurately simulating aqueous solvation.

Dr. Richard Judson
Senior member of the technical staff at Sandia National Laboratories, in
Livermore, CA. Judson has twelve years of experience in molecular modeling
using quantum mechanics, molecular dynamics, and statistical and
optimization methods. At Sandia he has headed a project in computational
drug design that produced new methods for drug-docking predictions, NMR
data analysis, and analysis of large databases of molecules. Other projects
have included modeling of electron impact on materials, design of laser
pulses for control of chemical motion, and the use of genetic algorithms
for protein structure prediction.

Postdoctoral Position at Brunel University

Applications are invited for a postdoctoral Research Fellow position in
the Department of Mathematics & Statistics, on an SERC Project titled
"Numerical Modelling of Fracturing of Rock Masses". The position is for a
period of 16 months from 1st May 1996.

The project, which is being funded by the Dept. of Trade & Industry as
part of their Coal R&D Programme, is supervised by Dr. M B Reed and Prof.
J R Whiteman. It aims to produce a finite element package to model
progressive fracture and break-up of underground rock masses, by
incorporating Discrete Element Method (DEM) concepts in an object-oriented
programming format. Such an object-oriented program has already been
written (in C++) for FEM analysis using an elasto-viscoplasticity material
model. The appointee would take over this program and add fracture and DEM
features, followed by testing and evaluation.

Applicants should have postgraduate experience of the finite element
method in solid mechanics applications, and a good working knowledge of
C++ programming.

Salary, on the RA1A scale, is in the range 14,317 - 21,519 pounds per annum,
plus a London Allowance of 2,166 pounds. An early appointment is sought.
Applicants should send a c.v. to Dr. M B Reed, either by email to, or by fax to (+44) (0)1895 203303. Please
include the email and/or fax addresses of two referees. Further details
can be obtained from Dr. Reed by email, fax or telephone: 01895 203281.

Brunel University is located on the Western edge of London, close to
