**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**

2003 BABUSKA PRIZE AWARDED

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

microstructure.

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

description.

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**

CALL FOR PAPERS

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

http://www.imm.dtu.dk/~jw/para04/

SCOPE:

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

CONTRIBUTIONS:

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

Workshop.

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
