Subject: Best Wishes to Prof. Schoenauer

At the end of September Professor Schoenauer will retire as deputy director
of the computing center of the University of Karlsruhe. However, he will be
still active as researcher. His focus will be, as before, the solution of
partial differential equations, the solution of large linear and nonlinear
systems and the efficient use of supercomputers. He will also continue to
develop black-box solvers (see
In particular, he will continue to complete and to keep up-to-date his
hand-written internet book "Scientific Supercomputing"

We wish him all the best for the future and we are looking forward to many
original contributions from him - as he can spare more time now for purely
scientific work.

Subject: Help on Splines

Dear Sir,

I am a phD student at the "Universite de Nice Sophia Antipolis"
in the South of France.

I work on microwave imaging which is an inverse scattering problem.

I have just joined the email database of NA-Net.

I am sending this mail to you hoping I could get help concerning
the following problem.

Consider N points in the plane. I would like to construct a curve
that passes through these points. The final curve should be
smooth enough (continuity of the first and second derivatives)
One should be able to specify whether the curve is closed
or open, as well as to give the values of the derivatives at
the start- and end points for example. The final curve should
be "natural looking".

I know that this is a rather classical problem and have used
piecewise natural cubic splines which guarantee the continuity of
the first and second derivatives at each point of the final curve.

However, the solution given by the cubic splines did not satisfy
me very much because I noticed that in the case of points describing
a wing section, there was a "brutal jump of the curvature" at the
vicinity of a point of inflexion.

That is why I am looking for a better solution.

I have been told that splines in tension could be a good solution
for my problem. What do you think about it ?

Could you please give me some advice and/or some references
for my problem ?

Thank you very much.

Yours faithfully.

Ralph Ferraye.

Subject: New Book on Splines and Wavelets

Title of the book: Complex Harmonic Splines, Periodic Quasi-Wavelets:
Theory and Applications
Author: Chen, Han-lin
Publisher: Kluwer Academic Publishers

In this book, the author studies the complex harmonic spline functions
(CHSF in abbreviation). Specifically, he explores the functional and
geometrical properties of CHSF in details. One can use CHSF to approximate
complex harmonic function to high accuracy. Since the shape of the domains
for a problem with practical interest may be complicated, it is important
to be able to work with an arbitrary domain. CHSF provides a good tool to
approximate a conformal mapping on the domain with arbitrary shape.

In the second part of the book, the author constructs various kinds of
periodic quasi-wavelets. These wavelets have least terms in the
decomposition and reconstruction formulas, and are orthonormal.
We also present a fast wavelet method for solving a kind of integral
equations and a kind of related partial differential equations by using
the wavelets. If the stiffness matrix are calculated beforhand, then in
computing the discretized equation, the complexity is O(N),
where N is the number of knots.

The last part of the book is the construction of a kind of periodic
interpolating wavelets. These wavelets possess a number of nice
properties: interpolation, localization, symmetry, smoothness up to any
desired order, real valued, bi-orthogonality and having explicit
representations. Therefore, we believe that they have potential values
in applications.

FIDISOL/CADSOL now freely available

The FIDISOL/CADSOL program package is now freely available for purely
scientific use.

FIDISOL/CADSOL is a program package for the solution of partial differential
equations. 2- and 3-dimensional systems of elliptic (stationary) and parabolic
(time-dependent) equations can be solved. The boundary conditions may be
arbitrary. The solution method is the finite difference method. For the FIDISOL
part the solution domain is restricted to be rectangular. For the CADSOL part
the domain is body-oriented, i. e. logically rectangular. There are versions
with an adaptive grid generation. For CADSOL dividing lines can be prescribed
allowing the solution of different partial differential equations in
different subdomains or allowing noncontinuous conditions inside the domain.

More information is available on the web site:
The program and all kind of description can be downloaded directly from the

Please notice: There will be no user support for FIDISOL/CADSOL as we do not
have enough manpower.

Graph partitioning is an important problem with extensive
applications in many different areas including scientific
computing, parallel processing, VLSI design, data-mining, and
efficient storage of large databases. For example, the
ability to find good partitionings of large irregular,
dynamic and adaptive meshes is critical for efficient
execution of many computational simulations on high-
performance computers.

A two-day workshop on graph partitioning applications is
being held at the Army High Performance Computing Research
Center (AHPCRC) at the University of Minnesota to bring
together researchers working on graph partitioning algorithms
as well as researchers who need partitioning techniques to
solve their problems.

The workshop will provide a forum for presentation of new
formulations as well as algorithms for graph partitioning and
novel, innovative applications of graph

Journal of Computer Research devoted to Industrial Applications of Parallel
Computing. It had a submission deadline of September 15th. Later we have
learned that the special issue will be published as the third (not second)
issue of the year, so we have more time. We have posted the new submission
deadline on the www site:

but this generated some confusion (as we started to receive messages asking

In this project the diffusion of passive and non-passive particles in
a turbulent flow is studied. Recently an asymptotic theory has been
developed which relates the diffusion coefficients for stochastic
turbulent processes to measurable Eulerian space-time velocity
correlation functions. We propose to assess the domain of validity of
the theory, both experimentally and numerically to foster the
synthesis and exchange of knowledge. To this end, LDA measurements in
a turbulent pipe flow will be carried out and large-eddy simulation
(LES) methods will be developed for the same flow.
For validation purposes, direct numerical simulation (DNS) of the flow
will be performed at relatively low Reynolds numbers. The experimental
results will be used to test subgrid models in the LES methods at
higher Reynolds numbers.
Next to the study of the turbulent flow, the motion of particles in
the flow will be investigated experimentally as well as numerically.
To this end equations of motion for the particles will be incorporated
in the DNS method.
In the long term this research may lead to a better understanding of
turbulence and to
improved diffusion models for dispersions in turbulent flows to be
implemented in turbulence models and CFD-codes.
We are looking for suitable candidates for the numerical part of the
project who will cooperate closely with the experimentalist.
Candidates for the Ph.D. position are required to have an M.Sc. degree
in mechanical engineering, physics, applied mathematics or equivalent.
Candidates must be fluent in english, both in writing and speaking.
Some experience with computer programming for scientific computing is
