Subject: Workshop on Numerical Control Software

NUMERICAL CONTROL SOFTWARE: a useful tool in industry
Friday, December 3, 1999, INRIA Rocquencourt, France
First Announcement and Call for Posters

This workshop organized by the European Numerics in Control thematic Network
(NICONET) aims to bring together engineers, mathematicians, computer
scientists and practitioners from industry and academia dealing with
numerical software in systems and control and their implementation and use
in industrial practice.

Recent advances on the use of numerical software libraries especially
designed for solving systems and control engineering problems in a
numerically reliable and efficient way will be discussed. The current
status of the freely available SLICOT library will be extensively discussed,
as well as industrial control applications and future extensions, comprising
parallel versions and practically oriented benchmarks. SLICOT is a valuable
tool for the reliable solution of many control problems, and for large-
scale, computer-intensive control problems and real-time applications,
SLICOT can lead to significant performance improvements.

Chairpersons: Francois Delebecque, Serge Steer (local organizers) and
Sabine Van Huffel (project coordinator).

Organizing Committee: T. Backx, P. Benner, A. van den Boom, J. De Cuyper,
A. Coville, D.W. Gu, S. Hammarling, V. Hernandez, B. Kagstrom,
M. Konstantinov, V. Mehrmann, A. Moner, P. Petkov, V. Sima, A. Stoorvogel,
P. Van Dooren, A. Varga, M. Verhaegen, R. Wohlgemuth.

Workshop Program:
The morning session consists of a tutorial training course including
demos of the newly developed SLICOT toolboxes which enable the use of
SLICOT routines within the user-friendly CACSD packages MATLAB and Scilab.
In the afternoon, plenary talks are scheduled describing the use of
numerical control software in diverse industrial control applications. In
addition, a poster session of contributed papers illustrates new
developments in control software and their performance in engineering
practice and industrial applications.

The preliminary, as well as the final program, will be announced on the
NICONET website

Subject: Position at United Technologies Research Center

The Dynamic Systems and Control Group at the United Technologies Research
Center invites qualified individuals to apply for an open position.

United Technologies Research Center (UTRC) is an internationally recognized
R&D organization that conducts research across a broad range of technology
areas in support of operating units of United Technologies Corporation
(UTC). The Dynamic Systems and Control Group is responsible for research
activities at UTC on dynamic systems and control. The activities include
control algorithm design and analysis, control implementations, and reduced
order modeling and analysis of dynamic systems. The activities are conducted
in order to advance the state-of-the-art in one or more UTC divisions: Pratt
& Whitney, Sikorsky, Otis, Carrier and Hamilton-Sundstrand. More information
on UTRC can be found at

Expertise is desired in large scale computing for dynamic problems
(stability analysis and unsteady phenomena). The applications currently
studied involve fluid dynamics, combustion, rotating machinery, and
acoustics. Tool development is needed in the areas of nonlinear dynamic
analysis (continuation and bifurcation analysis), numerical linear algebra,
nonlinear control strategies and numerical optimization. The position
requires experience in numerical analysis and computation that is relevant
for large scale dynamic simulation and analysis.

Each individual in the group participates in a variety of different
projects, all contributing to the solution of practical engineering
problems. The minimum requirement is a strong background in mathematics and
expertise developing scientific software. A master's degree in applied
mathematics, computer science or in a relevant engineering discipline plus
three years of professional experience developing and using computational
methods for dynamic problems, developing relevant numerical analysis
software (especially numerical linear algebra), or constructing control
algorithms is the current qualification expectation. A Ph.D is very
desirable. Preference will be given to candidates with expertise in: 1)
numerical methods for simulation and analysis of large scale dynamical
systems, 2) extraction of reduced order models from CFD or partial
differential equation models, 3) analysis and synthesis of nonlinear control
strategies for large scale systems, 4) demonstrated ability to work both
independently and as a member of a team.
