Subject: New book, Hierarchical Matrices

Hierarchical Matrices:
A Means to Efficiently Solve Elliptic Boundary Value Problems
M. Bebendorf
Lecture Notes in Computational Science and Engineering 63, Springer, 2008.

Hierarchical matrices are an efficient framework for large-scale fully
populated matrices arising, e.g., from the finite element discretization
of solution operators of elliptic boundary value problems. In addition to
storing such matrices, approximations of the usual matrix operations can
be computed with logarithmic-linear complexity, which can be exploited to
setup approximate preconditioners in an efficient and convenient way.

Besides the algorithmic aspects of hierarchical matrices, the main aim of
this book is to present their theoretical background. The book contains
the existing approximation theory for elliptic problems including partial
differential operators with nonsmooth coefficients. Furthermore, it
presents in full detail the adaptive cross approximation method for the
efficient treatment of integral operators with non-local kernel
functions. The theory is supported by many numerical experiments from
real applications.

The book is intended both as a text book for graduate students in
mathematics and as a reference work for mathematicians, scientists, and
engineers who deal with non-local operators in their fields.

Subject: 2nd Call: Workshop on Splitting Methods in Time Integration, Oct 2008

The Department of the University of the University of Innsbruck organizes in
collaboration with the numerical analysis group of the Universitie of Trieste
the fifth workshop in series on numerical analysis and scientific computing.
This year, the topic will be time integration of evolution problems; in
particular, we will cover splitting methods in time integration.

The intention of the workshop is to provide a platform for exchanging new
ideas and results in the development of numerical methods for evolution
equations. The emphasis will be laid on splitting methods for PDEs. We try to
cover both, theoretical and practical aspects, and we want to bring together
numerical analysts working in the field as well as PhD students who want to
start in this area.

Further information (including a preliminary list of participants) is
available on the Workshop Website
If you are interested in attending the workshop, please send an e-mail to .

Subject: Conference Optimization with interfaces and free boundaries, Mar 2009

Anouncement of the Conference on

*Optimization with interfaces and free boundaries*
*Regensburg, March 23-27, 2009

Optimization problems with interfaces and free boundaries frequently
appear in materials science, fluid dynamics, topology optimization,
biology, finance and in other applicational areas. Modelling of these
phenomena often yield variational problems and highly nonlinear partial
differential equations or inequalities. The analysis of these problems
including optimization of variational inequalities and geometric PDEs is
a notorously difficult task. The developement of efficient numerical
methods for the simulation of interface evolution and free boundaries as
well as for optimization problems with PDE constraints is a vastly
growing field.
The meeting will start with a spring school in which an introduction to
the topics of the conference will be given.
On Tuesday March 24th at 14:00 the meeting will proceed with the
Topics of the spring school:
* Modelling of interfaces and free boundaries (Harald Garcke)
* Optimization with PDEs (Eduardo Casas)
* Numerical approaches for interfaces and free boundaries (Charlie Elliott)
Confirmed invited speakers are Martin Burger, Eduardo Casas, Klaus Deckelnick
Charlie Elliott, Michael Hintermüller, Martin Rumpf.

Subject: Postdoc on Growth of water waves at Technion-Israel

Post-doctoral Scholarship sponsored by

Technion-Israel Institute of Technology
Department of Civil and Environmental Engineering

Title: Spatial and/or temporal growth of water waves in a wind-wave flume

Prof. Michael Stiassnie is seeking a suitable qualified researcher to
undertake Post-Doctoral study to develop a theoretical model for the growth
of water-waves in a wind-wave flume, under his supervision.

About Technion:
For more than eight decades, the Technion-Israel Institute of Technology,
which is located in Haifa, has been Israel's primary technological
university and the largest center of applied research. It is ranked among
the leading technological universities in the world. The Department of Civil
and Environmental Engineering has 60 senior faculty members active in
research and education, and they currently supervise the education of ~900
undergraduate students, ~240 master degree students, ~85 doctor students,
and ~10 post-doctoral researchers.

Project Abstract:
The importance of adequate description of interaction of wind with ocean
waves cannot be overestimated, both on the global level of earth climate,
and on a more local level of the necessity to predict the sea state for
practical operation of off-shore and near-shore facilities. The goal of this
study is to gain a better understanding of the dominant phenomena that
determine the growth of waves under the effect of wind in a laboratory
flume. This will enable us to offer better modeling of wind-wave growth
rate. To attain this goal, it is crucial to realize that as water waves are
affected by wind, the wind velocity profile in the vicinity of air-water
interface is strongly affected by the waves.
Detailed measurements of the air and water flow field in a laboratory wind-
wave flume and of the spatial and/or temporal evolution of the wave field
will be carried out by a partner team, lead by Prof. Lev Shemer at the Tel-
Aviv University. The experimental results will be compared with new
computations based on the solution of the Orr-Sommerfeld equation for the
experimentally determined air and water velocity profiles. Such a comparison
will lead to critical assessment of the underlying model assumptions and to
introduction of appropriate modifications. It is expected that an iterative
experimental-theoretical process will lead to a better understanding of the
physics of air-water flow interaction, in particular of the wind-wave growth
mechanism, and as a result to a more accurate theoretical description of
this process.

Selection Criteria
1. Ph.D. degree related to fluid-mechanics, obtained not earlier than
31.12.2005 (essential)
2. Strong analytical and mathematical skills (essential)
3. A good working knowledge of programming (desirable)
4. A good knowledge of English (desirable)
5. Experience in water-waves related research (advantage)

Subject: PhD / postdoc positions at the Technical University of Denmark

DIACON (Diabetes Control) is a research project that concerns development
of “Control Algorithms for Semi- and Fully-Automated Pen and Pump Insulin
Administration” to patients with type I diabetes. The project is funded by
NABIIT - the Danish Strategic Research council. The partners in the project
are DTU Informatics, DTU-Biosys, Hvidovre Hospital, and Novo Nordisk A/S. In
addition we collaborate with University of California at Santa Barbara and
Uppsala University.

DIACON Project
In this project we develop and test new technologies for treatment of
diabetes. The objective of the project is to construct systems that can
regulate and stabilize blood glucose levels in patients with type I diabetes.
These systems are variations of the so-called Artificial Pancreas. The
Artificial Pancreas consists of a subcutaneous glucose sensor, a control
algorithm, and an insulin pump. The sensor measures glucose levels under the
skin. This signal is used by the control algorithm to compute the correct
amount of insulin to inject in order to keep the blood glucose at its target
level. The computed amount is injected using the insulin pump. Glucose
sensors and insulin pumps are already available. The project and the 3
PhD/Post Doc positions focus on development of the automatic control
technology needed for the Artificial Pancreas. The topics of the 3 projects

1. Computational Systems Physiology (physiological models, simulation)
2. Adaptation to the Individual (System Identification)
3. Control Systems and Predictive Control Algorithms

The projects for the 3 positions (PhD or Post Doc) require significant
collaboration. At a later stage a medical PhD will be associated to the
projects in order to connect to clinical tests at Hvidovre Hospital.
