Subject: Request for information on mathematical models of forest fires

Dear Colleagues,

A PhD student, whom I know, is starting a study related to forest fires
in Bulgaria. She needs a reliable mathematical model, which she intends
to use with several sets of data. She may also work on implementation of
the model on parallel computers and computer grids as well as on testing
different numerical methods in the model. I shall be very grateful if
anybody, who can provide such a model, contacts me. I shall also
appreciate any information which may be useful.

Best regards,
Zahari Zlatev

Subject: High Performance Computing Ph.D. Fellowship Applications due Sept. 8

The ACM/IEEE Computer Society High Performance Computing (HPC)Ph.D.
Fellowship Program is now accepting nominations for its second annual
competition at The deadline
for submissions is Friday, September 8, 2008..

The ACM/IEEE-CS HPC Ph.D. Fellowship Program honors exceptional Ph.D.
students throughout the world with the focus areas of High Performance
Computing, Networking, Storage and Analysis. HPC covers the areas of
computational sciences, computational engineering, and computer
science using the most powerful computers available at a given time.
The ACM/IEEE-CS HPC Ph.D. Fellowship Program also supports the
sponsors' long-standing commitment to workforce diversity and
encourages nominations of women, minorities and all who contribute to

ACM/IEEE-CS HPC Ph.D. Fellowships are awarded with a certificate and a
stipend of at least $5,000 (US) for one academic year. All ACM/IEEE-CS
HPC Ph.D. Fellows are invited to attend at least one SC conference
(usually the one after one year of receiving the award). Furthermore,
the SC Steering Committee and other conference volunteers are willing
to facilitate, where possible, internships for Fellows at HPC research
or development sites. Interns are paid by their host site and will be
subject to the prevailing terms and conditions of the internship
program at that site. ACM/IEEE-CS HPC Ph.D. Fellowships are awarded
annually but previous awardees may compete annually to be renewed for
up to two additional years (three total), based on the Award
Recipient's continued exceptional academic standing, progress,
achievement, and sustained interaction with the HPC technical

Subject: New Book, Iterative Methods for Nonlinear Ill-Posed Problems

Iterative Regularization Methods for Nonlinear Ill-Posed Problems
B. Kaltenbacher, A.Neubauer, O. Scherzer
Radon Series on Computational and Applied Mathematics 6, de Gruyter, 2008

Due to rapidly evolving innovative processes in engineering and business,
more and more new nonlinear inverse problems arise. Since there is often too
little time to gain a deep understanding of mathematical and physical aspects
for deriving problem specific solution approaches, one needs algorithms that
can be used to solve inverse problems in their general formulation as operator
equations. It is a fact that many inverse problems are ill-posed in the sense
that noise in measurement data may lead to significant misinterpretations of
the solution, hence regularization methods have to be used for their stable
numerical solution. Whereas the analysis of such methods for linear problems
is relatively complete, the theory for nonlinear problems in Hilbert spaces is
developed to a much lesser extent. In the last years, iterative regularization
methods turned out to be an attractive alternative to Tikhonov regularization
especially for large scale nonlinear inverse problems. This book is devoted to
the convergence and convergence rates analysis of iterative regularization
methods like Landweber iteration, Newton type methods, multilevel algorithms
and level set methods derived during the last ten years.

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 inverse problems in their fields.

Volumetric image reconstruction in X-ray CT
Based at the Centre for Imaging Science INVERT
Supervisors: Dr Manuchehr Soleimani and Professor Cathryn Mitchell
Imaging is the science of building 2D or 3D reconstructions from exterior
measurements. The applications include medical tomography, geomagnetic
prospecting, ground penetrating radar, industrial non-invasive testing and
many others. Computational imaging algorithms involve the solution of large-
scale inverse problems. This project involves development of the sate of the
art image reconstruction for next generation of tomographic image
reconstruction in medical application.
The 3 year PhD research projects will take place in the INVERT centre of the
Electronics and Electrical Engineering University of Bath where the PhD
students will have opportunity to learn from and work with internationally
recognized experts in tomographic image reconstruction. A generous travel
budget is included to allow the students to present their research at
international conferences.
A degree in physics, engineering, mathematics, statistics or a numerate
subject is required. Some programming experience is desirable.
The PhD projects are fully funded, covering tuition fees and stipend (for UK
and EU students). Overseas students would need to cover the difference
between the EU fee and the overseas tuition fee. The EPSRC stipend is
expected to be in the range of £12000 - £13000 pa.

Expressions of interest and application should be sent by email, along with
a CV, to Dr Manuchehr Soleimani ( . The start date
for the PhD project can be 1st October 2008.
