Subject: Congratulations to Walter Gautschi
Prof Walter Gautschi of Purdue University was recently elected to the
prestigious Bavarian Academy of Sciences, The citation (translation) reads
Prof. em. Dr. Walter Gautschi, born 1927, is a professor emeritus of
mathematics at Purdue University in West Lafayette, USA. Gautschi,
born in Basel, is an internationally renowned applied
mathematician. His primary areas are numerical mathematics,
constructive approximation theory and the theory of special functions
(he is considered the world's leading expert for evaluating the latter).
Congratulations, Walter, and thanks for all the many elegant results you
have produced.

Subject: PDE Solver in Unbounded Domain Wanted
I am currently involved in a research project to recover elastic
properties of biological tissue. We need to solve the wave equation in
unbounded half space. Can someone recommend some hyperbolic PDE solver? It
would be better if it can solve elastic wave equation in 3D space.
I would appreciate your help.

Subject: Pseudospectra GUI for MATLAB
Version 1.2 of the Pseudospectra GUI for MATLAB is now released. This
new version includes only minor external changes, but can provide
speedups of a factor of up to TEN compared with previous versions; take
a look at the following examples (running on my Sun Ultra 5 with MATLAB 6):
opts.npts = 200 % Grid size of 200 by 200
tic; psa(gallery(5),opts); toc
% Old: 29 seconds, new: 6 seconds
opts.npts = 100 % Grid size of 100 by 100 (real matrix)
tic; psa(triu(randn(100)),opts); toc
% Old: 281 seconds, new: 26 seconds
opts.npts = 50 % Grid size of 50 by 50 (complex matrix)
tic; psa(toeplitz([-i pi i./[1:98]],-i./[1:100]),opts); toc
% Old: 294 seconds, new: 31 seconds
opts.npts = 40 % Grid size of 40 by 40
tic; psa(gallery('chebspec',500),opts); toc
% Old: 605 seconds, new: 128 seconds
This speed increase has mainly been obtained by re-writing the
computational core of the GUI as a C mex-file.

Subject: Bisection Algorithm
One of my undergraduate student is investigating the Bisection Algorithm
and how it never converges on to an even numbered root and always finds odd
numbered root ( Ref.'Which root does the bisection algorithm find?' by
George Corliss in "Mathematical Modelling:Classroom Notes", Ed.M.S.Klamkin,
SIAM 1995).
If all the roots are uniformly randomly distributed over the entire
initial interval then the algorithm will find odd roots with equal
probability. But it was observed that once the all the roots are
clustered, these probabilities change, depending very much on the
position of the cluster with respect to the initial interval and
bisected sub-intervals (His procedure in java simulates this scenario).
He seems to find no further information on these varying probabilities.
We would be much obliged if someone could inform us of any recent
developments in this area and/or where we can get hold of this information.
Thanks.

Wavelet Methods - Elliptic Boundary Value Problems and Control Problems
1. Ed. 2001, Teubner Verlag, (English)
78,00 DM, ISBN 3-519-00327-9
This research monograph deals with applying recently developed wavelet
methods to stationary operator equations involving elliptic
differential equations. Particular emphasis is placed on the treatment
of the boundary and the boundary conditions.
While wavelets have since their discovery mainly been applied to
problems in signal analysis and image compression, their analytic power
has also been recognized for problems in Numerical Analysis. Together
with the functional analytic framework for differential and integral
quations, one has been able to conceptually discuss questions which are
relevant for the fast numerical solution of such problems:
preconditioning, stable discretizations, compression of full matrices,
evaluation of difficult norms, and adaptive refinements. The present
text focusses on wavelet methods for elliptic boundary value problems
and control problems to show the conceptual strengths of wavelet techniques.

The research group Scientific Computing of the department of Computer Science,
K.U.Leuven, Belgium, has two vacancies for postdoctoral researchers on the
project `Computational Mathematics in Bio-processes'. This project is a
collaboration with two research teams working on biological process engineering
(microbial conversion, food production and processing).
We look for 2 postdoctoral researchers to work on the following topics:
* Multilevel iterative solvers for systems of 3D reaction-diffusion equations
To extend their postharvest storage life, fruits are often stored under
controlled conditions to decrease their respiratory activity. When the oxygen
concentration is too low, or when the carbon dioxyde concentration is too high,
a fermentative metabolism is induced which may lead to severe tissue damage.
A generic model for this phenomenon consists of metabolic network models for
the respiratory pathways, transport models for gasses and moisture inside the
fruit, and a model to track the moving interface between damaged and undamaged
tissue. Simulations using this model require methods to solve systems of
reaction-diffusion equations, defined on complex 3D-domains, extended with an
internal interface tracking equation. This project will concentrate on the
numerical aspects and the development of fast solvers, based, e.g., on
multilevel and domain decomposition ideas.
* Simulation, reduced-order modeling and control for reaction-convection-
diffusion equations and conservation laws with turbulence- and sedimentation
models.
The simulation of complex bio-reactor processes is based on coupled reaction-
convection-diffusion equations (with strong convection) with bio-chemical
reactions, and the equations for (usually turbulent) fluid flow with simple
models for sedimentation. The aim is to develop accurate numerical methods
for steady-state computation and time simulation of these equations. Since
these models are often too complex to be exploited in model-based process
design and control, model reduction techniques for PDE-based control will
be studied.
The candidates should have a good background in scientific computing. The
positions are intended for post-doctoral researchers and they are available
for 1 year, starting as soon as possible, and with the possibility of an
extension. More information about the research group can be found at

Subject: Studentship at University of Huddersfield
SCHOOL OF COMPUTING AND MATHEMATICS, UNIVERSITY OF HUDDERSFIELD
EPSRC CASE STUDENTSHIP IN NUMERICAL ANALYSIS (APPROXIMATION)
FOR RESTORATIVE DENTISTRY AND MEASUREMENT
An excellent PhD opportunity is available for a good
mathematically related graduate, or MSc student, preferably with
experience in numerical analysis (NA) or approximation theory and
computing, to work with Prof. J.C. Mason / Dr I.J. Anderson in a thriving
NA research group in Huddersfield in association with Edward Lynch,
Professor of Restorative Dentistry at Queen's University, Belfast.
Prof. Lynch is affiliated to the London School of Dentistry and consultant
to the co-operating body Natural White (an international manufacturer of
dyes and toothpaste - with UK base in London).
The CASE project involves developing new approximation algorithms and
metrics to model plaque and surface changes to teeth, including the
effective fusion of data taken from multi-angle scans with measuring
devices. The group has excellent facilities in an award-winning,
renovated 1865 textile mill, and the (UK resident) stipend is at least
#9,800 p.a. (+ possible age/dependancy allowances).
For full details, contact (email) j.c.mason@hud.ac.uk or
i.j.anderson@hud.ac.uk or (phone) 01484-472680 or 01484-472927 leaving
phone number, apply a.s.a.p. by sending a short CV plus two academic
referee names, and suggest early dates for a possible interview. A
nomination is needed as soon as is feasible for a start between now and
October 2001.

equations appearing in applied mathematics and mathematical physics. Theoretical
contributions/analysis, numerical algorithms and computer simulations will
be also within the scope of the journal. The journal will also concentrate
on the interaction between different fields of applied mathematics. In
this connection the journal will appreciate papers for publication.
