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. *.*.*.*.*.*.*.*.*.*.*.*.*.*.*.*.*.*.*.*.*.*.*.*.*.*.*.*.*.*.*.*.*.*.*.*.*.*.** Contributed by Sanjay Lall WWW CONTROL ENGINEERING LIBRARY =============================== The WWW Virtual Library on Systems and Control contains links to many sites around the world providing information related to control engineering.

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. ****************************************** * * * Positions * * * ****************************************** *.*.*.*.*.*.*.*.*.*.*.*.*.*.*.*.*.*.*.*.*.*.*.*.*.*.*.*.*.*.*.*.*.*.*.*.*.*.** Contributed by: David Hill LECTURESHIP IN ELECTRICAL ENGINEERING UNIVERSITY OF SYDNEY, AUSTRALIA FIXED TERM or TENURABLE Ref.

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. ****************************************** * * * Books * * * ****************************************** *.*.*.*.*.*.*.*.*.*.*.*.*.*.*.*.*.*.*.*.*.*.*.*.*.*.*.*.*.*.*.*.*.*.*.*.*.*.** Contributed by Robert Elliott. relliott@gpu.srv.ualberta.ca Title: HIDDEN MARKOV MODELS: ESTIMATION AND CONTROL Authors: Robert J.

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.

Email: kluwer@world.std.com (?) 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.

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.

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.
