Welcome to E-letter number 78 which consists (again) of two parts.

We plan to send out the E-letter monthly. The next issue of E-letter will
appear March 1. Please send contributions before this date. We encourage
contributors to provide essential information only. We reserve the right
to require contributors to cut certain parts of their contribution.

Apart from the regular archiving of E-letters in SCAD, most contributions
to E-letter are now stored in separate categories in the SCAD-archive. Also,
an attempt is made to set up automatic links from SCAD to software which is
advertised in the E-letter. Contributors who object to this way of archiving
should mention this to the editors.

We remind you of the following.

-1- Contributions have to be sent to: "eletter-request@win.tue.nl"

    It would be useful if articles are already sent in the format that we
    use, starting with a "Contributed by:..." and a title centered in the
    next line. Each line should be no more than 80 characters wide. Please
    respect the MAXIMUM LENGTH OF 6 Kb per contribution.

-2- You can subscribe to the E-letter by sending an (empty) e-mail message
    to "eletter@win.tue.nl" carrying the subject 'add' or 'subscribe'. You
    will be automatically subscribed and included in our mailing list.
    To unsubscribe from this list, send an (empty) e-mail message to
    "eletter@win.tue.nl" with the subject 'remove', 'delete' or
    'unsubscribe'.

-3- If your address changed first unsubscribe (using your old E-mail address)
    and then subscribe again (using your new E-mail address). If you can not
    use your old E-mail address any longer then send an E-mail to
    "eletter-request@win.tue.nl" and your old address will be removed
    manually. In case of any problems please send an E-mail to
    "eletter-request@win.tue.nl" and we will try to resolve the problem.

-4- Further information about the E-letter can be obtained by sending an
    (empty) e-mail message to "eletter@win.tue.nl" carrying the subject
    'info' or via the finger command: "finger eletter@wsbs08.bs.win.tue.nl"

-5- If you are using an editor to read this mailing and if at any point you
    wish to skip to the next article, you can accomplish this by searching
    for the string: *.**

                      Earthquake in Japan
            The Current Status in the Control/System Community

As reported by various media, the Kansai area, particularly the city of Kobe,
was attacked by a devastating earthquake on early morning of January 17,
1995.  The maginitude was 7.2, but the center of the earthquake was almost
right below the Kobe city, and the destruction was enormous.  Nearly 5,000
people got killed by the accident.

Right after the earthquake we Japanese received many email/phone messages,
inquiring upon our safety from all over the world. To this we are most
grateful.  Fortunately, all the people in the control theory community are
safe and sound.  While the damage to the city of Kobe, Kobe university was
very serious, and the fundamental functions of the city are not recovered,
the situation is now getting gradually under control, thanks to dedicating
help of volunteers and of people/governments outside Japan.   The water
supply has not come back to a large part of Kobe; the railway tracks have
been destroyed.  But all in all law and order are perfectly maintained (no
riot).  Almost everyone seems to hold the situation well under control.

As is known, Kobe is to be the conference site for the upcoming 35th IEEE
Conference on Decision and Control in December 1996. While the monorail
access (portliner) to the site is still not functioning, the conference
site, the Kobe Portopia Hotel and Kobe International Conference Center are
virtually damageless.  While more precise evaluation should be made later,
there seems to be relatively little damage to the conference site, and most
probably it will be completely recovered 2 years from now.

We -- I'm sure I'm also speaking for others -- would like to thank all
the friends in the control system community for their concerns and support.

CHANGES IN UK TELEPHONE/FAX NUMBERS

Readers may be interested to know, if they are not already aware of it, that
all UK telephone and fax numbers will have their city codes changed by
prefixing with a 1.  This will be obligatory from 1 April 1995, but can
currently be used.  For example, my telephone number in Brighton becomes:
+44 1273 678046 from outside the UK, and simply 01273 678046 from within the
UK.  London codes become (0)171 and (0)181.

                 EIA CDIF Technical Committee
                 -- Call for Participation --

-----------------------------------------------------------------------
        Title:          Call for Participation for
                        Control System Design Subject Area
-----------------------------------------------------------------------

1.  Introduction

There has been an increasing demand for data exchange between design and
analysis tools for control design systems tools. There have been several
attempts in the past to define a common exchange format, but none of them
succeeded in the marketplace.
The CDIF Technical Committee has standardized tool data exchange for
classical CASE tools already. The Control System Design Subject
Area will fit into that architecture, allowing data exchange between
CASE and CACSD tools as between CACSD tools themselves.
This is a call for participation to standardize data exchange for
CACSD tools within CDIF.

2.  Proposed Scope of the new Subject Area

The subject area could include, but is not limited to the following
concepts:
 * Algebraic blocks (adders, multipliers etc., algebraic functions of N
 inputs)
 * Interpolation tables (with N independent variables)
 * Trigonometric and logarithmic functions
 * Vector operations (such as scalar or vector products, matrix-times-vector
   calculations)
 * Dynamic blocks (integrators, transfer functions, delays,
   state-space-systems)
 * Data-Path-switches (influenced by boolean expressions)
 * Formal and Actual parameters for blocks.
Both time-continous and equidistantly sampled systems should be covered, as
should be their interfaces. Asynchronous systems could be covered.

3.  Proposed Schedule

It is assumed that the work on this subject area can make relatively fast
progress provided that enough participants are willing to contribute. A
working group draft proposal could be developed in possibly less than one
year. The principle will be to concentrate on the core concepts which are
most
requested by users for data exchange, and add more special concepts in later
revisions of the standard.

4.  Conclusion

This is a short version of a working paper which had been approved by the
CDIF Technical Committee at its November 1994 meeting. If you are interested
in contributing or if you have any further questions, do not hesitate to
contact the CDIF chair, Rob Hill, any member of the CDIF Technical Committee
or the author of this paper. Subscription to the CDIF mailing at
cdif@onramp.com list is possible.

                   1995 Graduate Student Fellowships
                           Sponsored by the
                 U.S. Environmental Protection Agency

The U.S. Environmental Protection Agency (EPA) invites applications for
graduate fellowships in academic disciplines at the forefront of
environmental science and technology: the physical, biological, and social
sciences; mathematics and computer science; and engineering. These
fellowships are intended to help defray costs associated with advanced
environmentally-oriented study leading to the masters or doctoral degree.
EPA expects to award approximately 100 new multi-year graduate
fellowships in 1995.

BACKGROUND

The mission of the EPA is to provide leadership in the nation's environmental
science, research, education, and assessment efforts; make sound regulatory
and program decisions; and carry out effective programs and policies to
improve and preserve the quality of the national and global environment.
Science and technology are central to virtually every aspect of environmental
protection and seem certain to take on progressively greater importance
during the foreseeable future.

ELIGIBILITY

Applicants must be citizens of the United States or its territories or
possessions, or lawfully admitted to the United States for permanent
residence.

EPA graduate fellowships are intended for students already enrolled into a
full-time graduate program at an accredited U.S. college or university.

Women, minorities, and disabled students who are pursuing graduate degrees in
one of the eligible fields are especially encouraged to apply.

                    PH.D. SUBJECTS PROPOSED

Four Ph.D. theses subjects proposed by
Laboratory: IRISA/INRIA Rennes, France
Research group: Automatic Control and Signal Processing.

Competitions for thesis fellowship are open, with deadlines February 28
for some of them, and May 30 for other ones. Expected starting time for
the thesis is autumn 1995.


Diagnosis of complex industrial systems
----------------------------------------
Advisor: Michele Basseville
(tel. : (33) 99 84 72 36, email: basseville@irisa.fr)

We have developed a general and systematic statistical approach for
designing monitoring (detection and diagnosis) algorithms. This approach
enabled us to formulate a new concept of `data-to-model' distance, in
which model, noise, and uncertainty characteristics are taken into account
in the design of the detection and diagnostics procedures. These methods
proved very powerful for early detection and diagnostics of small changes
in systems characterized by CONTINUOUS (as opposed to discrete) parameter
vectors. The two main applications have been vibration monitoring of
mechanical structures and rotating machines, and diagnosis of power gas
turbines.

But full diagnostics of complex systems requires to mix the results of the
above techniques with diagnostics of the DISCRETE part of the plant --
e.g., on/off actuators or sensors, availability of an underlying discrete
state, .... On the other hand, new hybrid numeric/symbolic stochastic
models have been made available recently.

The purpose of the thesis is to re-formulate the problems of detection
and diagnosis for mixed numeric/symbolic systems, using the new modelling
of these systems and the general approach mentioned above. The underlying
application could be gas turbines or a telecommunication network.


Multiresolution Segmentation of signals
----------------------------------------
Advisor: Albert Benveniste
(tel. : (33) 99 84 72 35, email: benveniste@irisa.fr)

Jointly with A.S. Willsky's group at MIT, we have developed a rich framework
for statistical multiresolution signal processing. Multiresolution signals
are signals jointly handled at all possible resolutions. The dyadic tree is
a natural index set for multiresolution signals. Each level of the tree
models a given level of resolution, and moving upward the tree amounts to
move to the next coarser resolution. A comprehensive system theory and
associated Kalman filtering have been developed for such models, with an
industrial application to multiresolution geophysical data fusion.

The objective of the thesis is to develop within this framework a set of
multiresolution signal segmentation techniques. Related algorithms would
have the desirable feature to automatically focus on the `right scale'
to perform statistical segmentation. Application will be possibly
considered in the same area as mentioned before.


An alternative to Belief Networks and new Models of Uncertainty
---------------------------------------------------------------
Advisor: Albert Benveniste
(tel. : (33) 99 84 72 35, email: benveniste@irisa.fr)

The SIGNAL `synchronous' language for specifying real-time  applications has
been developed and is available, both as an academic free software, and as a
commercial tool. SIGNAL is a block-diagram formalism which can be used to
describe real-time systems, prove properties, and generate executable code.
SIGNAL can specify an uncertain dynamical system, in which uncertainty is
modelled as an unknown feature with specified constraints. An extension of
SIGNAL, called SIGNalea, has been defined, which adds the possibility to
specify random systems. This model is  related to Dempster-Shafer belief
networks known in Artificial Intelligence.

Algorithms have been developed for system  simulation and for hidden states
estimation. For some systems, the method automatically generates the
simulation or estimation program from the system model. These methods are
not general, however. The purpose of this thesis is to develop alternative
techniques, related to the area of Markov Random fields in pattern
recognition,
known also as `Gibbs Sampling'.

Non-parametric Modelling and Monitoring of Industrial Processes
---------------------------------------------------------------
Advisor: Qinghua Zhang  (Email: zhang@irisa.fr)

We have a long experience on statistical methods for modelling and change
detection of dynamic systems.  Various applications have been studied, in
particular the monitoring of mechanical structures and gas turbine systems.

We have developed a general and systematic approach for designing detection
and diagnosis algorithms based on any adaptive identification algorithm.
This approach requires a mathematical model of the monitored system.
However, such a mathematical model is not always available for complex
industrial systems. The first objective of this thesis is to develop
non-parametric methods (wavelets, neural networks, etc.) for modelling
systems for which no or few physical knowledge is available. Based on the
above-mentioned general approach, the second  objective is to develop
monitoring algorithms associated with these non-parametric models. The third
objective is to develop monitoring methods based on semi-parametric models
which can incorporate partial physical knowledge.

>From the back cover:  The aim of this book is to present graduate students
with a thorough survey of reference probability models and their applications
to optimal estimation and control. These new and powerful methods are
particularly useful in signal processing applications where signal models are
only partially known and are in noisy environments. Well known results,
including Kalman filters and the Wonham filter, emerge as special cases.
The authors begin with discrete time and discrete state spaces. From
there, they proceed to cover continuous time, and progress from linear
models to nonlinear models, and from completely known models to only
partially known models. Key techniques include the change of probability
measure and the EM algorithm.

from the back cover:

"An excellent introduction to optimal control and estimation theory
and its relationship with LQG design .... invaluable as a reference for
those already familiar with the subject." - Automatica.

This highly regarded graduate-level text provides a comprehensive
introduction to optimal control theory for stochastic systems,
emphasizing application of its basic concepts to real problems.  The
first two chapters introduce optimal control and review the
mathematics of control and estimation.  Chapter 3 addresses optimal
control of systems that may be nonlinear and time-varying, but whose
inputs and parameters are known without error.

Chapter 4 of the book presents methods for estimating the dynamic
states of a system that is driven by forces and is observed with random
measurement error.  Chapter 5 discusses the general problem of
stochastic optimal control, and the concluding chapter covers linear
time-invariant systems.

Robert F. Stengel is Professor of Mechanical and Aerospace
Engineering at Princeton University, where he directs the Topical
Program on Robotics and Intelligent Systems and the Laboratory for
Control and Automation.  He was a principal designer of the Project
Apollo Lunar Module control system.

"An excellent teaching book with many examples and worked prob-
lems that would be ideal for self study or for use in the classroom ....
The book also has a practical orientation and would be of considerable
use to people applying these techniques in practice." - Short Book
Reviews, Publication of the International Statistical Institute.

"An excellent book which guides the reader through most of the
important concepts and techniques of the title subject .... A useful
book for students (and their teachers) and for those practising

of particular interest."  - Automatica.

"A valuable book which provides an illuminating insight into many
aspects of optimal control .... the reader finds the concepts and
methodology expounded in a progressive direct manner, marked by
clarity of insight and presentation .... This lucidly written book by
Stengel can be confidently recommended to anyone desiring to
develop a thorough working knowledge of the subject of stochastic
optimal control.  It should certainly find a place in the reference
library." - Robotica.

"... describes a body of techniques that is quite useful in determining
the best strategy for controlling a system in the presence of
uncertainty.... The power of stochastic optimal control becomes
apparent, as interpreted by notions drawn from classical control
applied to multi-input/multi-output systems .... Although many
interesting developments in control system analysis have been made
recently, optimality remains the most important unifying criterion for
control system synthesis." - IEEE Control Systems Magazine.

FROM THE BACK COVER
===================

The field of discrete event systems has emerged to provide a formal
treatment of many of the man-made systems such as manufacturing systems,
communication networks, automated traffic systems, database management
systems, and computer systems that are event-driven, highly complex, and not
amenable to the classical treatments based on differential or difference
equations. Discrete event systems is a growing field that utilizes many
interesting mathematical models and techniques. In this book we focus on a
high level treatment of discrete event systems, where the order of events,
rather than their occurrence times, is the principal concern. Such treatment
is needed to guarantee that the system under study meets desired logical
goals. In this framework, discrete event systems are modeled by formal
languages or, equivalently, by state machines.

The field of logical discrete event systems is an interdisciplinary
field---it includes ideas from computer science, control theory, and
operations research. Our goal is to bring together in one book the relevant
techniques from these fields.

Modeling and Control of Logical Discrete Event Systems is the first book of
this kind for the professionals in the area of discrete event systems.  The
book is also designed for a graduate level course on logical discrete event
systems. It contains all the necessary background material in formal
language theory and lattice theory. The only prerequisite is some degree of
``mathematical maturity''.  Several examples and exercise problems are
included in each chapter to facilitate classroom teaching.

CALL FOR PARTICIPATION

The 1995 SIAM Annual Meeting will focus on computational science and
engineering -- its applications, and the interdisciplinary interactions that
yield new perspectives on research, education, and the contribution of
mathematics to science and industry.

The meeting will highlight the role of mathematics and computation in the
areas of control of large systems, environmental modeling, multi-disciplinary
design optimization, and biology and chemistry. The meeting will also
emphasize the role of numerical algorithms and software in computational
science and engineering. The ever-increasing role of computation in these
fields has led many institutions to install interdisciplinary degree programs
that focus on computational science.

        Neural Adaptive Control Technology Workshop: NACT I
                         18--19 May, 1995
                     University of Glasgow
                         Scotland, UK

>> NACT Project

The first of a series of three workshops on Neural Adaptive Control
Technology (NACT) will take place on May 18--19 1995 in Glasgow,
Scotland.  This event is being organised in connection with a
three-year European Union funded Basic Research Project in the ESPRIT
framework.  The project is a collaboration between Daimler-Benz
Systems Technology Research, Berlin, Germany and the Control Group,
Department of Mechanical Engineering, University of Glasgow, Glasgow,
Scotland.

The project, which began on 1 April 1994, is a study of the
fundamental properties of neural network based adaptive control
systems. Where possible, links with traditional adaptive control
systems will be exploited. A major aim is to develop a systematic
engineering procedure for designing neural controllers for non-linear
dynamic systems. The techniques developed will be evaluated on
concrete industrial problems from within the Daimler-Benz group of
companies:  Mercedes-Benz AG, Deutsche Aerospace (DASA), AEG and
DEBIS.  The project leader is Dr Ken Hunt (Daimler-Benz) and the
other principal investigator is Professor Peter Gawthrop (University
of Glasgow).

>> NACT I Workshop

The aim of the workshop is to bring together selected invited
specialists in the fields of adaptive control, non-linear systems and
neural networks. A number of contributed papers will also be
included. As well as paper presentation, significant time will be
allocated to round-table and discussion sessions. In order to create
a fertile atmosphere for a significant information interchange
we aim to attract active specialists in the relevant
fields.

Proceedings of the meeting will be published in an edited
book format.

A social programme will be prepared for the weekend immediately
following the meeting where participants will be able to sample the
various cultural and recreational offerings of Central Scotland (a
visit to a whisky distillery is included) and the easily reached
Highlands.

>> Contributed papers

The Program Committee is soliciting contributed papers in the area of
neurocontrol for presentation at the conference and publication in
the Proceedings. Submissions should take the form of an extended
abstract of six pages in length and the

                DEADLINE is 1 March 1995.

Accepted extended abstracts will be circulated to participants
in a Workshop digest.

Following the Workshop selected authors will be asked to prepare a
full paper for publication in the proceedings.  This will take the
form of an edited book produced by an international publisher. LaTeX
style files will be available for document preparation.

Each submitted paper must be headed with a title, the names,
affiliations and complete mailing addresses (including e-mail) of all
authors, a list of three keywords, and the statement "NACT I". The
first named author of each paper will be used for all correspondence
unless otherwise requested.

Final selection of papers will be announced in mid-March 1995.
