Subject: Object Oriented Finite Element Library

Version 3.2 of the well-known deal.II object-oriented finite element
library has been released. It is available from the deal.II home-page

The most important improvements are:
- Mapping of arbitrary order at curved boundaries. This includes the
possibility of using sub-, iso-, and super-parametric elements, as
well as C1 mappings and shape functions depending on the actual grid
- A matrix class for conveniently filtering Dirichlet boundary values
without modifying the system matrix.
- A wide variety of target systems by ISO C++ conformance.
Beside these, the list of changes comprises more than 100 new
functions, classes, and bug fixes. A concise list with respect to the
previous version can be found at

All main features of the previous versions have been continued and

book. For more information please visit Thank you!


Introduction to Algorithms
second edition
Thomas H. Cormen, Charles E. Leiserson, Ronald L. Rivest, and Clifford Stein

There are books on algorithms that are rigorous but incomplete and others
that cover masses of material but lack rigor. Introduction to Algorithms
combines rigor and comprehensiveness.

The book covers a broad range of algorithms in depth, yet makes their
design and analysis accessible to all levels of readers. Each chapter is
relatively self-contained and can be used as a unit of study. The
algorithms are described in English and in a pseudocode designed to be
readable by anyone who has done a little programming. The explanations have
been kept elementary without sacrificing depth of coverage or mathematical

The first edition became the standard reference for professionals and a
widely used text in universities worldwide. The second edition features new
chapters on the role of algorithms, probabilistic analysis and randomized
algorithms, and linear programming, as well as extensive revisions to
virtually every section of the book. In a subtle but important change, loop
invariants are introduced early and used throughout the text to prove
algorithm correctness. Without changing the mathematical and analytic
focus, the authors have moved much of the mathematical foundations material
from Part I to an appendix and have included additional motivational
material at the beginning.

Thomas H. Cormen is Associate Professor of Computer Science at Dartmouth
College. Clifford Stein is Associate Professor of Industrial Engineering
and Operations Research at Columbia University. Charles E. Leiserson is
Professor of Computer Science and Electrical Engineering at the

Subject: New Book on Applied and Computational Control

Applied and Computational Control, Signals, and Circuits -
Recent Developments ( Biswa Datta, Editor).

Kluwer Academic Publishers, Boston, is pleased to announce the
publication of the book "Applied and Computational Control, Signals,

This is the second book in the series. Biswa Nath Datta of Northern
Illinois University is the Founding Editor and Editor-in-Chief,
Roland Freund, Floyd Hanson and Robert Plemmons are the Associate
Editors-in-Chief and Daniel Pierce is the Software Editor of this

It is an interdisciplinary book blending mathematics, computational
mathematics with control and systems theory, signal processing and
circuit simulations.

The book contains six technical chapters: three in control,
communication and power systems, one in signal processing and two in
circuit design and simulations. Besides these technical
chapters, the software section contains a chapter on the description
and analysis of a software module for model reduction from
the SLICOT library.

The chapters present overviews of some of the recent developments
in three inter-related areas of control, signal processing and
circuits and were written by leading experts in these fields on
invitation by the editor-in-chief. The invitations were extended
to the authors, based on recommendations made by our distinguished
editorial board. The chapters should be accessible to a wide
interdisciplinary audience: from experts to beginning researchers
and graduate students. It is expected that the book will be an
important reference book for research scientists, practicing
engineers, as well as students and teachers in control, power
systems, signals, and circuit theory. The book also is suitable
for advanced graduate topic-courses.

PhD position at Technical University of Eindhoven

Numerical simulation of air film cooling

Project description
For the optimisation of air film cooling of surfaces exposed to hot gasses,
like in turbine blades, detailed knowledge of the heat transfer processes at
the blade surface and the influence the geometry of the film cooling nozzles
is essential. At the technical university of Eindhoven a joint project
between the departments of Mathematics (Scientific Computing Group) and
Mechanical Engineering (Energy technology) is studying this problem both by
numerical simulation and by experiments. The project is carried out in
cooperation with industry. The numerical part of the approach will consist
of developing a new numerical flow model, which is able to catch the details
of turbulence transition. Instead of using diffusive turbulence models this
new model uses direct numerical simulations (DNS) on those areas where
transition occurs. To ensure sufficient accuracy on all scales so called
local defect correction techniques will be used, where the Scientific
Computing Group has a considerable expertise. Moreover the programming will
be done in a state of the art programming environment, NumLab (which is
object oriented).

Profile of the candidate
The qualified candidate should have completed an academic education (i.e.
have a degree on MSc level or equivalent) in the area of applied and
computational mathematics or physics /engineering with a thorough knowledge
of mathematical and computational tools, in particular fluid dynamics.

The position is a research position for 4 years (after one year an
evaluation of the progress is made, leading to a continuation, if positive).
There is ample possibility to follow courses, though no examination in
either of these is required. Special PhD courses are provided within the
graduate school J.M. Burgers Centrum.
Gross monthly salary varies from DFL 3338 (first year) to DFL 4,511 (fourth
year), plus 8% additional holidays allowance.
