Subject: Symposium in Helsinki on Cardiovascular Hemodynamics

Ragnar Granit Institute at Tampere University of Technology and
CSC - Scientific Computing in co-operation with Finnish society for
Medical Physics and Medical Engineering are organizing the Symposium

"Cardiovascular Hemodynamics from Modeling to Clinical Applications"

in September 13-14, 2001, Helsinki, Finland.

The goal of the symposium is to bring together clinicians, modelers, and
persons working in medical imaging. The emphasis is on the present and
emerging clinical applications of modeling and on new possibilities for
measuring cardiovascular functions.

Virtual surgery and virtual patient are emerging tools formed by recent
development in medical imaging, measurement of physiological signals and
computational modeling. New modalities in magnetic resonance and ultrasound
imaging provide fundamental information on the anatomy and dynamics of the
cardiovascular system. These are the key elements in constructing models of
this complex system. The new possibilities to model blood flow and the
hemodynamic control system provide novel clinical information by combining
the measured data, physical phenomena and computational tools. These tools
help to develop better measurement methods of the key cardiovascular
functions such as the cardiac output.

More information about this symposium is available from the web-side

Subject: Conference at UCLA Honoring Stanley Osher

First Announcement
International Conference on Scientific Computing,
Partial Differential Equations and Image Processing
On the Occasion of Stanley Osher's 60th Birthday
April 5-7, 2002, UCLA

There have been very rapid developments of efficient algorithms
on scientific computing and related investigations of mathematical issues
of partial differential equations and image processing over
the past decade. As a result, many problems in diverse application
fields such as fluid dynamics, material science, image processing,
computer vision, and computer graphics in the entertainment industry can
now be routinely simulated to high resolution. Stanley Osher has been in
the forefront of many of these developments, and has published many
influential original works on high resolution shock capturing schemes, level
set method, applications to multi-phase flows, computer vision, TV based
image restoration, just to name a few areas.

On the occasion of the 60th birthday of Stanley Osher, the
International Conference on Scientific Computing, Partial Differential
Equations and Image Processing will be held at UCLA on April 5-7, 2002,
to commemorate his achievement. The main purpose of this conference
will go far beyond a birthday celebration, rather it will
review recent developments and explore exciting new directions
in scientific computing and partial differential equations for time
dependent problems and its interaction with other fields such
as image processing, computer vision and graphics.
An emphasis of this conference, which hopefully will set it to be
different from others, is the strong interaction of
significant mathematics with advanced algorithms applicable to
real world applications. It is very natural for this conference to
be held at UCLA as this seems to be the tradition and strong spirit
of both the UCLA mathematics department and the new Institute for
Pure and Applied Mathematics.

The conference committee consists of Russel Caflisch, Weinan E,
Bjorn Engquist (chair), David Gottlieb, Mohamed Hafez, Guillermo Sapiro,
Chi-Wang Shu and Hongkai Zhao. Tentative list of invited speakers

Yann Brenier, Mathematics, Paris 6 University, France.
Ronald Coifman, Mathematics, Yale University.
David Donoho, Statistics, Stanford University.
Bjorn Engquist, Mathematics, UCLA.

Computational Linear Algebra with Applications
(Milovy 2002),
August 4-10, 2002, Milovy, Czech Republic

As announced earlier (Na Digest 50(2000), December 10), following
the successful meeting on Iterative Methods and Parallel Computing
in 1997 ( we will organize
from August 4th to 10th, 2002 the second Milovy meeting (Milovy 2002).


The meeting will be held at the Devet Skal Hotel (literally "Nine
Rocks"; in Milovy,
a small village located in the Bohemian-Moravian Highlands about
100 kilometers (65 miles) from Prague. A bus from Prague to Milovy
will be arranged on August 4 (leaving at 4 p.m.), and from Milovy
to Prague on August 10; scheduled arrival to Prague at 2 p.m.

Scientific Program:

The meeting will concentrate on computational methods, namely on
methods of numerical linear algebra, their (parallel) imple-
mentations and applications. Based on the contributions, we plan
to structure the program into subthemes like, e.g., matrix theory
and its applications, sparse direct solvers, iterative methods for
linear systems, preconditioning techniques, large-scale eigen-
problems, inverse problems and regularization. Special attention
will be paid to application areas not restricted to PDE's,
control, optimization or image processing. We will keep the format of
the program similar to the Milovy 1997 meeting, with periods of free
time in the afternoons for unstructured discussions. The scientific
program is planned for full 5 days (Monday through Friday), with
a free Wednesday afternoon reserved for an excursion.

Research position at the Fraunhofer Institute for Algorithms and
Scientific Computing, formerly GMD-SCAI -- Sankt Augustin, Germany

The project SACADA - Synoptic Analysis of Chemical Constituents from Satellite
Data with 4D-Data-Assimilation within the Fraunhofer Institute for Algorithms
and Scientific Computation offers a research position. The position is for
three years.

The project will deliver an efficient method for chemical data assimilation
which will be used operationally at the DLR in Oberpfaffenhoven.
Based on a global weather forecast program an higher order advection scheme
or a semi-Lagrangian scheme will be implemented. Special aspects of
parallelisation like width of the overlap-area have to be taken into account.
To improve the efficiency of the assimilation scheme the preconditioning method
has to be improved. Different approaches to reduce the size of co-variance
matrices have to be investigated.

Applicants should have finished computational meteorology or applied
mathematics with diploma or PhD, having experience in
partial differential equations, adjoint methods, preconditioning methods,
parallelization, numerical methods for general circulation models.

Experience in using parallel computers including PC-Cluster and MPI is desired.
Knowledge in UNIX or Linux and programming skills in Fortran or C are necessary.
