EGERVARY-ABS INTERNATIONAL PRIZE

With reference to the intensive development of the ABS methods since 1981

at the University of Bergamo and to the seminal albeit little known works

of the late professor Egervary where the class of algorithms later called

the unscaled ABS class is already developed, an international prize is

offered by the Department of Mathematics of the University of Bergamo for

the best work in the ABS field authored by a single author whose age on

December 31, 1997, is no more than 39 years.

The prize consists in the sum of italian lire two millions, plus travel

expenses (economy class if by air) and living expenses for three days, to

come to Bergamo to present in a seminar the content of the winner paper.

Submitted papers can be either in preprint or already published form. They

must be sent to: The Director, Department of Mathematics, University of

Bergamo, p.za Rosate 2, 24129 Bergamo, Italy. Age must be certified by a

copy of the passport. Papers must be received by June 30, 1998.

The winner will be decided by an international commission of experts in

ABS methods. The winner will receive the prize in Bergamo, where he is

due to present his work.

The second edition of my book on "Green's functions and boundary value problems"

is being published by Wiley in Dec. 1997. About 25 to 30 % of the material has

been changed from the first edition. Although not dealing directly with

numerical methods, the book could serve effectively as background or companion

to a more numerically oriented course. The principal changes in the new

edition are in the areas of modeling, Fourier analysis, variational principles,

finite elements, fixed-point theorems,inverse problems , asymptotics, and

nonlinear methods. Throughout, I try to maintain a balance between sound

mathematics and meaningful applications.

**Subject: HQP Now Available from the NEOS Server**

The NEOS Server is now offering HQP for the solution of nonlinearly

constrained optimization problems in SIF format. HQP is suitable for

large nonlinearly constrained problems with sufficient sparsity

structure.

HQP implements a sequential quadratic programming algorithm that uses

an interior point algorithm for the solution of quadratic programming

subproblems and performs direct factorization of large sparse

matrices.

An interesting feature of the integration of HQP into NEOS is that

problems are solved at the Internet-enabled optimization service at TU

Ilmenau, Germany.

You can try out HQP by visiting the NEOS Server at

The Workshop will be organized by the Department of Stochastic

Simulation of St. Petersburg State University in cooperation with

the INFORMS College on Simulation (USA). St. Petersburg Workshop

on Simulation is a regular international conference of high level.

The main part of participants are recognized experts in the field

of simulation and experimental design and are invited personally.

Nevertheless the workshop is open for researchers who want to

present there results as well as for practitioners interesting in

the application of sophisticated mathematical techniques who would

like to participate without a paper presentation.

The 1st Workshop (May 24-28, 1994) and 2nd Workshop (June 18-22,

1996) showed that there exists mutual interest in the exchange of

ideas between scholars from Russia and from the West. The Third

Workshop will be devoted to further development and application of

sophisticated mathematical techniques to the solution of actual

problems in Stochastic Simulation and Experimental Design.

The end of June is the time of famous white nights and wonderful

weather in St. Petersburg. Participants will visit the remarkable

museums and theaters of the city.

Workshop topics:

Methodology of computer simulation

Stochastic simulation in physics and mechanics

Simulation and modelling in economics

Random number generators, simulation of random processes

Computer networks

Queueing system theory

Variance reduction techniques

Statistical methods in simulation

Optimal experimental design theory

Extremes of random processes

ADVANCED SIGNAL PROCESSING FOR MEDICAL MAGNETIC RESONANCE SPECTROSCOPY

The research group SISTA (Signals, Identification, System Theory and

Automation) of the Department of Electrical Engineering (ESAT) at the

Katholieke Universiteit Leuven, Leuven, Belgium, has an opening for one or two

researchers on the European TMR (Training and Mobility of Researchers) project

``Advanced signal processing for medical magnetic resonance imaging and

spectroscopy''.

In this project, the group develops with 8 other European groups

a fully automatic, user-friendly software package for the quantitation and

imaging of metabolites (MRS, MRSI) in clinical and medical research

environments. Magnetic Resonance Spectroscopy (MRS) enables to detect and

quantify metabolite concentrations in the region of interest in a subject.

MRS Imaging (MRSI) provides an image of the concentration of each metabolite

of interest. We extend/tune the MRS/MRSI software to distinct wishes of

industry and our user group comprising 100 teams, worldwide. This

multidisciplinary project covers mathematics, informatics, electrical

engineering, physics, biochemistry, medicine, and biology.

The new researcher will mainly contribute to the automation of metabolite

quantitation, especially for clinical environments. The signal-to-noise ratio

of MRS and MRSI signals being low, its task will consist of the development

and automation of robust model-based signal processing techniques that

accommodate any available chemical and instrumental prior knowledge.

The candidate should have a background in numerical linear algebra and

signal processing. The position is intended for a young EC researcher and

may lead to a Ph.D., but also post-doctoral researchers may apply.

The position is available for 3 years, starting January 1998.
