Subject: James Lyness 1932-2010

James Lyness, a distinguished member of the Mathematics and
Computer Science division at Argonne National Laboratory and a
leader in the development of multidimensional numerical
quadrature, passed away on Sunday, December 5, 2010. He had
suffered from cancer for much of the year.

James received his D.Phil at Oxford. He held positions in
Singapore, Australia, and Oak Ridge before coming to Argonne in
1967. He became a Senior Scientist in 1980 and retired in
1998. He was selected for Emeritus status, a title granted to the
most distinguished retired scientists and engineers at Argonne.

James continued to do research until shortly before his death.
His last paper appeared in 2010 in the book "The Birth of
Numerical Analysis", a collection of articles by pioneers in the
development of numerical analysis. James will be remembered not
only for his scientific contributions but also for his love of
travel, good wine, good food, and good friends. He will be missed
by his many friends and collaborators around the world.

Subject: Function Evaluation Time Benchmarks

Hi all,

I've been working on a function library that guarantees extended
precision results - fast. However, I could not find a benchmark
with which to compare execution times, and would very much
appreciate some help. For example, using a PC, how long does it
take to evaluate (with guaranteed extended precision) the Bessel
function of the first kind with both index and argument =3D 100?

For comparison, using an AMD Athlon, 2.6 GHz CPU, my program
needs 283 microseconds; including in- and output on the 80-bit
FPU stack.

Subject: Mondriaan 3.11: Sparse matrix partitioner and reorderer

We are happy to announce new extensions to our software package
Mondriaan. Of general interest is an extension to the Matrix
Market format, described first in the list of additions:

- The Extended Matrix-Market (EMM) output format enables the
storage of many matrix-like objects in a single file. It can
easily and portably be used to share complex
matrix/vector-formulated problems. As EMM remains close to the
original Matrix-Market format, existing parsers are envisioned to
be adapted with minimal effort. For Mondriaan, this optionally
decreases the number of output files from 5 or more, to a single

- The hierarchy of the separator blocks is now included in the
output, for all permutation strategies. This enables building a
full binary tree out of the block structures.

- Mondriaan can now force symmetric permutations, that is,
generate PAP^T for general A. In particular, Mondriaan is now
able to retain the symmetry of symmetric input matrices.

- The symmetric finegrain splitting strategy. This represents a
symmetric sparse matrix A using half the number of vertices and
hyperedges, compared to the regular finegrain method.

The revised Mondriaan package and its documentation can be found

The documentation includes a first draft of the Extended
Matrix-Market format. The Mondriaan code is in ANSI C and is
distributed under the LGPL license.

Subject: 2 PhD Positions, K.U. Leuven

2 PhD Positions: Numerical methods, computational tools and
software for the analysis and control of LPV systems.

The analysis and control of linear systems with varying
parameters, so- called linear parameter-varying (LPV) systems,
have become major research areas. LPV systems arise naturally
when modeling manufacturing systems (wafer stages, pick-and-place
robots, overhead cranes =E2=80=A6), chemical processes such as liquid-gas
separation, electro-hydraulic systems and active suspension
systems, automotive engines, etc. In most of these applications
the system dynamics are also inherently infinite-dimensional,
characterized by a spatio-temporal distribution of state
variables, and subject to uncertainty or variability.

The aim of the project is to develop numerical methods,
computational tools and software for the analysis and control of
linear infinite-dimensional systems with time-varying
parameters. These methods should cope with uncertainty on the
system model and must be capable of designing optimal controllers
with a prescribed order or structure, where optimality refers to
robust stability and performance measures. The project also
includes the experimental validation of the obtained control
design methodologies on a mechatronic test setup.

The PhD positions result from a collaboration between the
Scientific Computing Research Group and the Department of
Mechanical Engineering of the K.U. Leuven, which both participate
in the interdisciplinary Optimization in Engineering Center
OPTEC. Both divisions will host one PhD student, whose projects
will be oriented towards computational methods and control
design, respectively. They will be jointly supervised.

Optimierung fuer robustes virtuelles FAhrzeugdesign), sponsored
by the German Federal Ministry of Education and Research (BMBF).

The goal of the project is to apply established a posteriori
finite element error estimation techniques to time-dependent
coupled systems of rigid and elastic bodies, so-called flexible
multibody systems. In this context, algorithms for the time
integration of differential- algebraic systems will be coupled
with methods for non-linear solid mechanics.

The ideal candidate has a Master's Degree in Applied Mathematics

number is available at Applied Mathematics Research Centre of
Coventry University (UK). The candidate must be an EU citizen.
The Studentship Award comprises a Maintenance Grant of =C2=A312,867
plus Home/EU fees equivalent.

The project concerns the study of instabilities in the buoyant
convective flows in the presence of high magnetic fields. The
work is mainly numerical, involving spectral methods using
MATLAB. These methods developed previously for the flows in the
absence of the magnetic field will need to be extended for the
magnetic case and applied to the flow in an infinite layer of
fluid with longitudinal temperature gradient. The mechanisms of
instability for different wall conductivities, Hartmann numbers
and orientation of the magnetic field and the layer need to be
understood. The role of Alfven waves in these flows is of
particular interest.
