Subject: netlib news

If you've had occasion recently to submit codes to netlib,
you'll have noticed the increased role of David Gay and
the move of netlib.bell-labs.com to netlib.sandia.gov.
David had retired from Bell Labs a few years ago and
moved to Sandia. In April, I retired from Bell Labs
and moved to Google in Mountain View, California. I'll
continue to help maintain netlib, but my work is
now security more than numerics. Having been a fan of
David's software for many years, I was delighted when
he agreed to take on an expanded role.

With any luck, these changes will remain almost
invisible and you'll get everything you need unchanged
at http://www.netlib.org.

Subject: Finite element test problems wanted

For some time now, we have been working on developing new out-of-core
direct solvers. These codes are designed to solve large-scale linear
systems using a multifrontal algorithm, optionally holding the matrix
data, its factors and some of the workspace used by the algorithm
out-of-core. The first release is for real matrices. We are
currently looking for test problems from practical applications.

For element applications, our solvers accept the problem data
element-by-element. Thus we need problems in unassembled format. The
University of Florida Sparse Matrix Collection is an excellent source
of test data but it currently holds very few problems in unassembled
element format.

We would be really grateful if anyone can provide us with test data in
unassembled format (in particular, we currently need unsymmetric
element problems). Ideally, we would like the data in Rutherford
Boeing format (see: RAL-TR-97-031, I. S. Duff , R. G. Grimes,
J. G. Lewis, "The Rutherford-Boeing Sparse Matrix Collection" which
can be downloaded from
http://www.numerical.rl.ac.uk/reports/reports.shtml) But if you have
data in some other format, please let us know.

We would be happy to share with you our experiences of solving your
problems using our solvers.

Many thanks
Jennifer Scott and John Reid, The Rutherford Appleton Laboratory

Collaborative Decision Making and in particular, addressing the
question of how to support Collaboration in Decision Making? Welcome
answers will incorporate key elements to deal with the complexity of
supporting collaborative decision making. Expected contributions will
try to answer to some of the following questions:
Where does the data for collaborative decision making come from
and how is it assembled?
Who is, or should be, involved in making the decision?
How do teams collaborate to build up common understanding?
How to Tackle Complexity in decision making and decision
support? A special focus on Data, Models and Actors will be
taken into account.

Subject: Phd position, CASA, Eindhoven Univ. of Technology, The Netherlands

PhD position: Modeling and control of an electron microscope in
Eindhoven University of Technology, Department Mathematics and Computer
Science, Center for Analysis, Scientific Computing and Applications
(CASA), prof.dr. R.M.M. Matteij

Required: MSc in mathematics, physics, electrical engineering, systems
and control, or a related field. The applicant should have good
analytical and modeling skills as well as good communication skills.

Research topic: Modeling and control of an electron microscope. The
research will concentrate on image analysis. From observed images we aim
to reconstruct the geometry of the observed entity as well as the (or
some) control settings of the microscope. The ultimate goal is to
automate the electron microscope's controls for inserted specific
specimen under, in order to get focused, astigmatic etc. images without
the aid of the user. The research includes the modeling how the image
depends on the microscope's controls and specimen as well as the related
optimization to match desired images. The microscope can be modeled
based on FEM direct computations or database based interpolations. Just
as the specimen all should be modeled in such a representation that
calculations can take place as fast as possible. Iterative and
non-linear solution techniques will be exploited to get an efficient
optimization procedure.

Applications should be addressed to: r.m.m.mattheij@tue.nl

Please include: Presentation letter; Curriculum Vitae; List of MSc.
Grades; List of people for recommendation.

Starting date: As soon as possible.

The salary is conforming the Dutch VSNU salary scale for PhDs.
