**Subject: MODLER Update**

I have updated MODLER to version 9.0. This is now a choice under linux...

see my software page at

http://www-math.cudenver.edu/~hgreenbe/consortium/software.html

The primary changes pertain to tables:

1. CHANGE spec added to TABLE in reading data file allows table revisions.

2. Table storage reduction by recognizing binary-valued types.

The previous version (8.2) is still available too.

You might start with my home web page, as it has other items of interest,

such as my Mathematical Programming Glossary.

Thanks,

Harvey J. Greenberg

Design Optimization (MDO). The papers are from a large number

of areas comprised by MDO, such as applications, multidisciplinary

optimization methods, optimization-oriented disciplinary developments,

computational environments, and other areas.

The intended audience of this book are both the researchers already in

interdisciplinary fields and those computational scientists,

mathematicians, and engineers who would like to become acquainted with

a large subset of components that make up MDO and with a multitude

of open research questions. I would also recommend this book as

reading material in graduate numerical analysis, applied optimization,

design, and engineering courses, as a potential source of interesting

research problems.

"Identification of Parametric Models from Experimental Data"

Springer-Verlag, Berlin-Heidelberg, 1997

The presentation of a coherent methodology for the estimation of the parameters

of mathematical models from experimental data is examined in this volume. Many

topics are covered including the choice of the structure of the mathematical

model, the choice of a performance criterion to compare models, the optimization

of this performance criterion, the evaluation of the uncertainty in the

estimated parameters, the design of experiments so as to get the most relevant

data and the critical analysis of results.

There are also several features unique to the work such as an up-to-date

presentation of the methodology for testing models for identifiability and

distinguishability and a comprehensive treatment of parametric optimization

which includes greater consideration of numerical aspects and which examines

recursive and non-recursive methods for linear and nonlinear models.

**Subject: CSDP, A Library for Semidefinite Programming**

CSDP is a library of routines that implements a predictor corrector

variant of the semidefinite programming algorithm of Helmberg, Rendl,

Vanderbei, and Wolkowicz. The main advantages of this code are that it

is written to be used as a callable subroutine, it is written in C and

Fortran for efficiency, it makes effective use of sparsity in the

constraint matrices, and that it includes support for linear

inequality constraints in addition to linear equality constraints.

The code has been tested under Linux, SunOS 4.x, Solaris 2.5.1, and

AIX 4.2. Makefiles are included for all of these operating systems. It

should be relatively easy to port the code to other versions of unix.

**Subject: Workshop on Software for PDEs**

SOFTWARE for PDEs , TUTORIAL / WORKSHOP

IMA HPC - YEAR

APRIL 21-25 1997

Purpose: The purpose of this tutorial/workshop is to

discuss actual software for the numerical solution

of PDEs with realistic demonstrations of the software

by international experts that have been directly involved

in the software development.

The emphasis is NOT on large, scale commercial packages,

such as, for example, NASTRAN and ANSYS (for structural analysis)

but more on special and/or general purpose systems that

can be used in research and development as well as in

teaching at universities.

This workshop precedes the IMA-HPC workshops

10) Grid Generation and Adaptive Algorithms,

11) Parallel Processing of Discrete Problems,

12) Parallel Solution of PDE

and should give a good background for these events as well.

Format: Each software system will be allocated a half

day in the workshop. Such a session should normally

contain:

a) A lecture by one of the developers giving an overview

of the software, its use and limitations.

b) A demonstration of the software (advanced application)

by one of the developers

c) Some simple application exercise using the software

that can be tried/carried out by the participants

d) A general discussion among the participants of the

software system, including Q/A based on the experience gained.

All SW packages will be installed on the IMA computer system

before the workshop. An SGI workstation will be available in the

auditorium with suitable projection to a large screen for the

participants. It is assumed that the presentations will include

`live' computer demonstrations.

The last day will be used to discuss future developments

of SW for PDEs and summarize the first four days.

The presenters and their packages include:

Olivier Pironneau

University Pierre et Marie Curie

FreeFEM

Hans Petter Langtangen

University of Oslo

DIFFPACK

Stefan Turek

University of Heidelberg

**Subject: Graduate Scholarship at Konrad-Zuse-Zentrum **

The Konrad-Zuse-Zentrum fuer Informationstechnik Berlin (ZIB), a research

institute of the state of Berlin, performs research and development in the

field of application oriented algorithmic mathematics. With effect from

April 1, 1997 a

Graduate Scholarship

is available at ZIB for a term of up to three years. The scholarship is

granted by the Graduiertenkolleg "Temperature Dependent Effects for Therapy

and Diagnostics" at Humboldt University Berlin (speaker: Prof. Dr. R. Felix).

The research work involves problems in

Computational Geometry, Image Processing,

and Scientific Visualization.

It should be carried out in close connection to the research performed in

the Sonderforschungsbereich 273 "Hyperthermia in Oncology: Methods and

Clinic".

RESEARCH TOPICS

- data structures for deformable grid models

- algorithms for deforming anatomical grid models

- algorithms for mapping grid models to atlas data for segmentation and

classification.

REQUIREMENTS

- good up to excellent degree in mathematics, computer science or

theoretical physics

- profound knowledge in areas of applied mathematics, e.g. splines,

wavelets, grid generation

- good acquaintance with object oriented programming in C++

- desirable: practical experience with large software projects

- interest in medical problems

or willingness to learn the missing parts.

We expect a high degree of commitment. In return we offer an interesting

field of work, an opportunity for creativity, excellent machinery equipment

and favourable working conditions.

We particularly encourage female applicants, since women are underrepresented

in science and ZIB is engaged in enlarging the quota.

Disabled persons will be preferred on terms of equal qualification.

Applications with photo, curriculum vitae in tabular form and customary

documents quoting the title "Graduiertenkolleg -- Scientific Visualization"

should be submitted to
