Subject: New Book on Higher-Order FEM and hp-Adaptivity

New Book on Higher-Order FEM and hp-Adaptivity:

Higher-Order Finite Element Methods
By Pavel Solin (Rice University, Houston, TX),
Karel Segeth (Academy of Sciences of the Czech Republic, Prague),
Ivo Dolezel (Czech Technical University, Prague).
Published by Chapman & Hall/CRC Press (July 2003),
Studies in Advanced Mathematics, Vol. 41;
ISBN 158488438X, Catalog No. C438X;
408 pages, 78 tables, 201 figures, companion CD-ROM.

The book provides a clear introduction and a comprehensible,
detailed survey of state-of-the-art higher-order finite element
methods and their practical implementation. It focuses on
hierarchic finite elements for approximations conforming to
spaces H^1, H(curl), and H(div), and provides fast access to
concrete, explicit formulae for computer implementation. In
its last chapter an efficient and robust strategy for automatic
goal-oriented hp-adaptivity is presented. The companion CD-ROM
contains tables of best known Gaussian integration points and
weights for all standard 2D and 3D reference domains up to the
order p=20 together with Mathematica verification routines.

Subject: New Book on Numerical Grid Methods

A new monograph numerical grid issues:
Liseikin V. "A Computational Differential Geometry Approach to Grid
Generation" Springer, Berlin
(ISBN 3-540-14008-5), has been recently published. Some Intellegence
you can find in

The book is devoted to the implementation of results of the theories of
regular and Riemannian geometries into formulation of grid models and
analysis of grid properties. It gives an account of the geometrization
of the popular comprehensive grid methods and presents an important extension
of the methods, related to the application of the technique of Riemannian
manifolds to the formulation of grid equations by developing some procedures
for the construction of monitor metric tensors.
The tensors are designed by generalizing the projection approach in which
the monitor metric in an $n$-dimensional physical geometry is borrowed from a
natural metric of the $n$-dimensional surface derived by a height monitor
function over the geometry. The book establishes and reviews some of the
relations of the Riemannian geometry for the purpose of obtaining new
equations with implemented metric characteristics aimed at facilitating
control of the generation of grids with the required quality properties.
Taking advantage of the relations established, the equations are converted
into a compact form convenient for the numerical treatment by the available

The technique of multidimensional differential geometry is also applied to
study of the qualitative effect of a general class of monitor metrics on the
resulting mesh. For this purpose a new characteristic of grid clustering is
formulated. Certain relations between this measure and some geometric
characteristics of grid hypersurfaces and the monitor functions forming the
monitor metrics are established. The well-known results for grids generated
by Laplace equations about node clustering near concave boundary segments of
domains and node rarefaction near convex ones are extended, using the
relations, to arbitrary multidinensional boundary segments and to more
general elliptic equations formulated for generating grids. On the basis of
the formulas established the monitor functions are readily estimated in the
popular Poisson, diffusion, and generalized Laplace elliptic models of
grid equations to provide grid clustering or, if it is reasonable, grid
rarefaction near arbitrary segments of physical geometries.

The book also includes a chapter concernd with the implementation of the
comprehensive grid equations into a numerical code.

Subject: SIAM Workshop on Combinatorial Scientific Computing

SIAM Workshop on Combinatorial Scientific Computing (CSC04)
February 27-28, 2004
Hyatt at Fisherman's Wharf, San Francisco, CA

Combinatorial algorithms play a key supporting role in many aspects
of scientific computing. Examples include orderings for sparse
direct methods, graph coloring and partitioning for parallel
computing, geometric algorithms in mesh generation and string
algorithms in computational biology. The enabling importance of
combinatorial algorithms in scientific computing is often overlooked,
and subcommunities of researchers with overlapping interests are
often unaware of each other. To address this fragmentation
and to strengthen the ties between the scientific computing and
discrete algorithms communities, SIAM is sponsoring a workshop
on Combinatorial Scientific Computing (CSC04).

CSC04 will be organized following the 11th SIAM Conference on Parallel
Processing for Scientific Computing (PP04) on February 27 and 28, 2004.
The workshop aims to bring together researchers interested in applications of
combinatorial mathematics and algorithms to scientific computing.

Plenary speakers include Richard Brualdi (Wisconsin),
Shang-hua Teng (Boston and Akamai), and Dan Gusfield (UC Davis).
Contributed presentations in lecture format are invited in all areas
consistent with the workshop themes.
A 2-page extended abstract, in PDF format,
of a proposed talk should be submitted to Sivan Toledo,, by electronic mail before October 31, 2003.
Authors will be notified of acceptance by e-mail
on or before November 30, 2003.

Funds have been requested to provide partial travel support
for graduate students, post-doctoral fellows,
and faculty in the early stages of their careers.

Delft Center for Systems and Control
Delft University of Technology
The Netherlands

The new center for Systems and Control
has a vacancy for a Ph.D. student within the
Dutch NSF (NWO) financed project entitled

"Model Reduction Algorithms for Nonlinear Dynamical Systems"

This project aims at development of structured and computationally
efficient model reduction algorithms for nonlinear systems.
The developments are based upon the so-called nonlinear balancing
theory, and should result in useful tools for dealing with classes of
complex nonlinear systems. For achieving this goal, both system
theoretical and numerical developments have to be made.

We are looking for a candidate having an M.Sc. degree and a
background in numerical analysis and/or systems and control. Candidates
are expected to be interested in fundamental research and in working
on the boundary of several research domains. A good command of the
English language is required.

The appointment will be for four years and as an employee
you will receive a competitive salary as well as good
secondary benefits. In the first year you will join the excellent
graduate program of the research school DISC (Dutch Institute for
Systems and Control), possibly in combination with courses in the
field of numerical analysis. You will work under the supervision of
Dr. ir. J.M.A. Scherpen and Prof. dr. ir. M.H. Verhaegen.
