Subject: ADMAT, Automatic Differentiation for MATLAB

Dear Colleagues,

ADMAT -- an Automatic Differentiation toolbox for MATLAB
is now available. ADMAT can compute derivatives of programs written
in MATLAB (i.e., M-files), e.g. the gradient, the Jacobian or the Hessian
matrix. ADMAT is very easy to use, it can compute derivatives of
most M-files and very easy to plug-into other MATLAB toolboxes.

Our research web page
has more information about our Automatic differentiation project
and efficient computation of sparse and structured derivative
matrices using AD technology.

To download get the following tarred and compressed file:

ADMAT runs under MATLAB version 5.0 and above. Read the file ADMAT/README
for information on documentation and user guide and some test applications.

PS: ADMIT, a toolbox which can compute derivatives of functions written in
C/C++ (via ADOLC tool) is also available from

Subject: Conference on Modern Trends in Computational Physics

The First International Conference on Modern Trends in Computational
Physics (MTCP'98) was held on June 15-20, 1998 in the Laboratory of
Computing Techniques and Automation, Joint Institute for Nuclear Research,
Dubna, Russia. The Conference was dedicated to the 5th anniversary of the
foundation of the Department of Computational Physics.
More than 150 scientists from 18 countries presented 25 plenary talks
and about 120 short communications at the Conference. The objective was to
provide a forum for the presentation of new approaches to computational
modeling in physics, namely numerical and computer algebra methods and
algorithms, computational tools for simulation and analysis of physical
processes, mathematical modeling of nonlinear static and time-dependent
physical fields, modeling exotic systems, Monte Carlo modeling of
interactions of particles and of particles with matter, problems of
nonlinear mathematical physics, modeling in ecology and biophysics, large
scale scientific computations on advanced computer architectures, and
software for physics experiments.
The MTCP PROCEEDINGS will be published in a form of special issue of CPC
(Computer Physics Communication) Journal by "Elsevier Science Publishers"
(The Netherlands).
We kindly invite all colleagues to participate in the 2nd International
Conference on Computational Physics, which is scheduled on mid June 2001.

Subject: Minisymposium on Matrices with Sparsity Structure

Minisymposium on "Matrices with sparsity structure"

in the framework of
the Second Workshop on "Large-Scale Scientific Computation"
Sozopol, Bulgaria, June 2-6, 1999

Organized by:

Marcin Paprzycki, University of Southern Mississippi, MS, USA,

Plamen Yalamov, University of Rousse, Bulgaria,

The minisymposium will be concerned with algorithms for matrices with a
sparsity structure, e.g. banded, tridiagonal, general sparse, bordered,
etc., their high-performance implementation and stability properties. We
are kindly inviting all interested individuals to contact the organizers
or the conference secretary.

(MP: this one below is slightly misleading as it suggests that the
proceedings will be of the Minisymposium -- and not the whole conference)

Proceedings consisting of all refereed and presented at the workshop papers
(only!) will be published in a book form. The intention of the workshop
organizers is to establish a tradition publishing the workshop volumes in the
VIEWEG Series Notes on Numerical Fluid Mechanics. A more detailed information
about the proceedings of the previous workshop is available on the WWW-sites.


Deadline for submission of extended abstracts (1 page) January 15, 1999

Subject: Graduate Positions at University Erlangen-Nuremberg


The Institute for Applied Mathematics of the University Erlangen-Nuremberg,
Germany, is searching candidates for two positions connected with research
projects in applied mathematics.

The first project is funded by the German Federal Research and Education
Department for three years. It deals with model, algorithm and software
development for the prediction of unsaturated subsurface contaminant
transport and remediation strategies. The transport processes are modelled
by nonlinear partial differential equations. The project is embedded
in a PhD program on applied mathematics / scientific computing.

The second project is carried out in cooperation with the Institute
of Material Sciences of the University Erlangen-Nuremberg and a
medium size enterprise of casting technology. Its subject is the
mathematical modeling and numerical simulation of solidification and solute
transport in the casting of alloys. The models are nonlinear partial
differential equations. The project is supported by the Bavarian Research
Foundation for two years, a prolongation of the project is planned.

The ideal candidate for one of these positions has a degree in mathematics
or a similar subject. He / She should be familiar with applied mathematics
/ scientific computing and / or partial differential equations. Knowledge of
the German language is not expected and only advantageous as far as
everyday life is concerned. The candidate is expected to write a PhD thesis
during the work on the project.

Salary is according to the German BAT IIa/2 tariff for both positions.
It depends on age and family status. (A 25 year old unmarried person
receives about DEM 33,000 / US$ 20,000 gross payment per annum.)

Candidates which are interested in one of those positions should contact
me as soon as possible and provide their CV, testimonies of their academic
education (if possible in English or German translations) and a description
of their scientific background and interests. One or two references of
university teachers would be also helpful.
