Subject: Bounds for Basis Functions

Dear colleagues,

I am searching and collecting references about bounds for the basis
functions in finite element spaces. Using TeX notation, I am mainly
interested in the uniformity condition

$$ \vert \varphi_j \vert \leq C h^{s-l} $$

where $\varphi_j$ is any basis function, $h$ is the mesh size, $s$ is
the order of the derivatives appearing in the definition of the degree
of freedom associated to $\varphi_j$ and $\vert . \vert$ is a Sobolev
semi-norm of order $l$. I would greatly appreciate any hint about
references where these bounds are explicitly proven for specific
elements (such as Argyris, Bell, Clough-Tocher) or where general
techniques of proof are developed.

Thanks in advance

Subject: 2003 Babuska Prize


In December 2003, the Czech Association for Mechanics and the Union
of Czech Mathematicians and Physicists again awarded the I. Babuska
Prize for the best work in scientific computing submitted by students
and young scientists.

The Prize winner for 2003 is Dr Jan Zeman from the Klokner Institute
of the Czech Technical University in Prague. The work honored is his
PhD thesis Analysis of composite materials with random

Further winners were delivered diplomas of honor. The second and
third positions were shared by Dr Milan Hokr from the Faculty of
Mechatronics of the Technical University in Liberec who presented his
PhD thesis Model of flow and solute transport in dual-porosity media
and Dr Alena Pozivilova from the Faculty of Mechanical Engineering of
the Czech Technical University in Prague who submitted her PhD thesis
Constitutive modelling of hyperelastic material using the logarithmic

Further diplomas of honor were delivered to MS theses. The first
position in this category was taken by Martin Zitka from the Faculty
of Mathematics and Physics of Charles University in Prague for his
thesis Higher-order finite element method for systems of nonlinear
parabolic differential equations.

The second and third positions were awarded jointly to Martin
Lanzendoerfer (Faculty of Mathematics and Physics of Charles
University in Prague) for his thesis Numerical simulation of flow in
a bearing and to Petr Stehlik (Faculty of Applied Sciences of the
University of West Bohemia in Pilsen) for his thesis Methods of
nonlinear analysis for differential equations on time scales.

The prize as well as the diplomas are awarded every year and they are
connected with a financial support.

The prize was established in 1994 by an outstanding Czech
mathematician Ivo Babuska. He was born in Prague and after graduating
from the Faculty of Civil Engineering of the Czech Technical
University in Prague he started his work in the Mathematical
Institute of the Academy of Sciences. He was appointed professor at
Charles University in Prague in 1968 and since fall 1968 he has been
working in the United States. Since 1995 he is at the Institute for
Computational Engineering and Sciences, University of Texas, Austin,
TX. His scientific work is focused on numerical and applied
mathematics and computational mechanics, and their use in practice.
His results in the finite element method belong to the fundamentals
of the method. He is the author of several monographs. In 1956 he
established the journal Applications of Mathematics published in
Prague. He also has initiated several famous scientific meetings
being organized both in Europe and the United States.

Subject: Minisymposium in Lyngby on HPC in Earth and Space Science

Minisymposium on
"High-Performance Computing in Earth and Space Science"
to be held in conjunction with the
PARA'04 Workshop on
State-of-the-Art in Scientific Computing
June 20-23, 2004
Technical University of Denmark
Lyngby, Copenhagen, Denmark

High-performance computing facilities enable simulations of physical
phenomena with ever increasing fidelity and accuracy. The range of
resolved scales in a single simulation, as well as the number of physical
processes included, yield results that can be directly compared with
observational data.

However, these simulations face complexity on various levels. The codes
have to be carefully designed in order to make use of the sophisticated
hardware. Combining legacy codes into multi-physics models requires the
choice of appropriate data structures to avoid excessive data
transformation. And finally, sophisticated tools are needed for the
analysis, reduction and management of the large data sets generated by
these codes.

Our primary goal is to present state-of-the-art examples of large-scale
earth and space science simulations. Scientific success resulting from
such simulations, as well as present limitations, are both of interest.
In addition to providing an overview of high-performance computing in
earth and space science, this mini-symposium is expected to identify key
areas where new efforts will be required.

Topics of interest include, but are not limited to:
- Space and laboratory plasmas
- Dusty plasmas
- Global climate models
- Multi-physics models
- Astrophysical dynamics and flows
- Gravitational models
- Kinetic, fluid and hybrid models
- Unconventional models and new algorithms
- Performance optimization
- Libraries for earth and space science problems
- Data handling, analysis and visualization
- Model validation and comparison with observations

A limited number of contributed, either 15 or 20 minutes talks will be
selected for this minisymposium. Short abstracts at most one page
should be sent before February 1, 2004. The text should be in pure ASCII
format. The acceptance of these abstracts will be sent no later than
February 29, 2004.

After acceptance, extended abstracts, at most 7 pages, should be sent
before April 15, 2004. Two format versions are needed, the latex, and
postscript or pdf. The pictures must be as encapsulated postscript files
(eps). The extended abstracts will be handed out at the beginning of the

After the conference, full papers, at most 10 pages, formatted according to
the rules of the LNCS, in order to be published in the PARA'04 proceedings,
should be sent before September 15, 2004. The author's instructions and
style files for the LNCS can be found at

These submitted papers will be reviewed, and the incorrect and wrongly
formatted papers will have to be submitted again. Some papers may be
selected for publication in special issues of regular scientific journals.

Technical University of Denmark, DK-2800 Lyngby, DENMARK
