It is conducted in cooperation with the Society for Industrial and Applied Mathematics (SIAM) and the Operations Research Society of America (ORSA). The thirty-first CDC will be held on December 16-18, 1992, at the Westin La Paloma, Tuscon, Arizona. The General Chairman of the Conference is Tamer Basar of the University of Illinois at Urbana-Champaign. The Program Chairman is Sergio Verdu of Princeton University. The conference will include both contributed and invited sessions. Papers and Sessions are hereby solicited in all aspects of the theory and application of systems involving decision, control, optimization and adaptation. CALL FOR CONTRIBUTED PAPERS AND INVITED SESSIONS The 31st CDC Program Committee will be soliciting two types of contributed papers for presentation at the Conference: REGULAR PAPERS describing completed work in some detail. Authors should submit seven (7) copies of the full paper for review. Each paper must be headed with paper title, the names, affiliations and complete mailing addresses of all authors, and the statement ``31st CDC''. The first named author will be used for all correspondence unless otherwise requested. A regular conference paper may simultaneously be submitted for possible publication as a regular paper in the IEEE Transactions on Automatic Control if requested. Please consult the Information for Authors which appears on the back cover of each issue of the Transactions. Submissions must be received no later than MARCH 1, 1992, by the Editor of the Transactions, Professor N. H. McClamroch, whose address can be found at the end of this CALL. Submissions by fax or electronic mail cannot be accepted. SHORT PAPERS that present important recent or perhaps preliminary results. Authors should submit four (4) copies of a 4-6 page detailed summary (plus references) for review. Each summary must be headed with the paper title, the names, affiliations and complete mailing addresses for all authors, and the statement ``31st CDC''. The first named author will be used for all correspondence unless otherwise requested. Submissions must be made (again only hard copies) no later than MARCH 1, 1992, to the Program Chairman, Professor Sergio Verdu, whose address can be found at the end of this CALL. Authors of papers in both categories will be notified regarding acceptance of their papers for presentation at the CDC by July 6, 1992. Authors of accepted papers will be provided with publication kits and instructions for preparing their manuscripts for the Proceedings. Authors of regular papers will be requested to keep their manuscripts to six Proceedings pages or less (about 6,000 words). Short papers will be limited to two Proceedings pages (about 2,000 words). There will be a mandatory page charge for each additional page. Authors of accepted papers are expected to attend the Conference to present their work. INVITED SESSIONS: The 31st CDC Program Committee is also soliciting proposals for invited sessions. The Program Committee particularly encourages cohesive sessions focusing on new emerging areas and/or sessions built around theme problems. Such session proposals will have priority over those of a classical or mainstream flavor. Four (4) copies of proposals should be submitted by MARCH 1, 1992, to Professor Robert R. Bitmead, Program Vice-Chair (Invited Sessions), at the address given at the end of this CALL. Proposals for invited sessions should contain the names, affiliations and complete mailing addresses of the session organizer(s), chairperson, co-chairperson and all authors, paper titles, abstracts, and detailed extended summaries of all papers. The organizers must include in the proposal: (i) a clear statement on the topic and the purpose of the session, (ii) a clear statement on the importance/relevance of the topic to the field, and (iii) a reasonably detailed description of how the papers form a cohesive, well integrated exploration of the session topic. The detailed extended summaries must be minimum of 2000 words, covering all contributions of the paper in sufficient depth to permit informed review. Organizers are encouraged to consider launching a session with a tutorial/survey paper which can be allotted twice the time accorded to regular papers. The Committee also invites proposals for technical sessions on topics for which it is most effective to have the audience converse with the author while standing close to view displays of computer terminals, video tapes, diagrams and/or photos/posters. The same deadlines and submission requirements as above apply to proposals in this category. The organizers will be contacted before May 11, 1992, concerning the tentative disposition of their sessions. Additional information may be requested at the time. Final selection of invited sessions will be announced by July 6, 1992. Addresses for Submissions: -------------------------- REGULAR PAPERS: Professor N. H.

Henderson, University of Utah Local Arrangements: Kenneth Hunt, University of Glasgow Publications Chairman: Barry A. Shepherd, Turing Institute Finance Chairman: William Leithead, University of Strathclyde Having evolved in the USA the 7th IEEE International Symposium on Intelligent Control (ISIC-92) will be held for the first time in the UK. The theme for ISIC-92 will be "Learning in Control". Artificial intelligence techniques have begun to enter control engineering. The requirement for an accurate mathematical model of the process to be controlled and the inability to set meaningful goals for the adaptive mechanism are the two major difficulties in designing an adaptive controller using conventional control theory. The expert controller equipped with the control engineers' knowledge and skills overcomes these two major difficulties. Expert controllers with an automatic learning capability must be built, controllers that learn through transferring the skill of the expert by a tutorial process. That is the machine must be able to build up its skill in the domain automatically in the form of appropriate control actions triggered by the sensed state variables. This skill transfer phase can be through elicited rules, passive learning or machine learning. Although machine learning has been applied widely in the control of complex dynamic systems, learning from Computer Aided Design (CAD) and interactive graphic representations and models is still in its infancy. In ISIC-92 we hope to attract discussion on this form of learning when applied in the automated manufacturing workcell, teleoperation domains, and at the architecture specification level. Papers are being solicited for presentation at the Symposium and publication in the Symposium Proceedings. Topics of interest include but are not limited to: - Intelligent Control for Process System - Reasoning Under Uncertainty - Machine Learned Control - Neural Network Controllers - Perception for Task Control - Multisensor fusion - Autonomous and Teleoperated Robotics - Active Sensing and Perception - Qualitative Modelling - Fault Diagnosis and Monitoring - Adaptive and Self-Organising Systems - Discrete Event Systems - Intelligent Manufacturing Systems - Knowledge-Based Automation - Fuzzy Control - Linguistic Control - Autonomous Control Systems - Mechatronic System Control - CAD and Interactive Graphics - Hierarchical Controllers - Space, Underwater, and Teleoperated Robots - Hypermedia Design Tools - Relational Databases for Control Control -Other Related and Novel Topics - Bio-engineering Five copies of papers should be sent by February 15 to: Thomas C.

Bacciotti LOCAL STABILIZABILITY OF NONLINEAR CONTROL SYSTEMS by Andrea Bacciotti (Politecnico di Torino, Italy) World Scientific, Series on Advances in Mathematics for Applied Sciences - Vol. 8 (expected publication date: Dec. 1991) This new book aims to present the stabilizability problem for nonlinear systems in a well organized and detailed way: the problem, its motivation, features and results. Control systems defined by ODE's are dealt with. Many worked examples are included. The main focus is on the mathematical aspects, but some important applications are also described. The contents includes: a sketch of the linear theory, the linearization method, relationship between controllability and stabilizability, certain versions of the Liapunov function approach, local approximation techniques, the critical cases and the center manifold method, cascade systems, bilinear systems, homogeneous systems, low dimensional systems. *.*.*.*.*.*.*.*.*.*.*.*.*.*.*.*.*.*.*.*.*.*.*.*.*.*.*.*.*.*.*.*.*.*.*.*.*.*.** Contributed by F.M.Callier New Book : F.M.Callier and C.A.Desoer, LINEAR SYSTEM THEORY, Springer-Verlag, New York, 1991,(ISBN 0-387-97573-X (U.S); ISBN 3-540-97573-X; price: 59.50 $) This volume is intended for engineers in research and development and for applied mathematicians. It is also designed to be a useful reference for graduate students in linear systems with interests in control. With this purpose in mind, the discrete-time case is treated in an isomorphic fashion with the continuous-time case. This volume is self contained: four mathematical appendices develop the many specializerd mathematical results needed in the main text. In the development of LINEAR SYSTEM THEORY emphasis is placed on careful and precise exposition of fundamental concepts and results. The main topics of LINEAR SYSTEM THEORY are treated systematically: the dynamics of linear time-varying and time- invariant systems; stability; controllability and observability; linear feedback and estimation; linear quadratic optimal control; finally the last chapter develops the main results of unity-feedback MIMO systems. At various suitable places basic computational issues and robustness issues are discussed. *.*.*.*.*.*.*.*.*.*.*.*.*.*.*.*.*.*.*.*.*.*.*.*.*.*.*.*.*.*.*.*.*.*.*.*.*.*.** Contributed by: zeman@sbee.eng.sunysb.edu (Prof. Armen H. Zemanian) Title: INFINITE ELECTRICAL NETWORKS Author: A.H.Zemanian Publisher: Cambridge University Press 40 West 20th Street New York, N. Y. 10011 (800-872-7423) Taken from the Dust Jacket: This is the first book to present the salient features of the general theory of infinite electrical networks in a coherent exposition. Using the basic tools of functional analysis and graph theory, the author presents the fundamental developments of the past two decades and discusses applications to other areas of mathematics and engineering. The jump in complexity from finite electrical networks to infinite ones is comparable to the jump in complexity from finite-dimensional to infinite-dimensional spaces. Many of the questions conventionally asked about finite networks are currently unanswerable for infinite networks, while questions that are meaningless for finite networks crop up for infinite ones and lead to surprising results, such as the occasional collapse of Kirchhoff's laws in infinite regimes. Some central concepts have no counterpart in the finite case, for example, the extremities of an infinite network, the perceptibility of infinity, and the connections at infinity. The first half of the book presents existence and uniqueness theorems for both infinite-power and finite-power voltage-current regimes, and the second half discusses methods for solving problems in infinite cascades and grids. A notable feature is the recent invention of transfinite networks, roughly analogous to Cantor's extension of the natural numbers to the transfinite ordinals. The last chapter is a survey of applications to exterior problems of partial differential equations, random walks on infinite graphs, and networks of operators on Hilbert spaces.

If you have a student or know of a student who should be included in the competition, here are the details: The student authors of the three best papers in applied and computational mathematics submitted to SIAM will be invited to attend the 1992 annual meeting in Los Angeles, July 19-24. Each winner must present his/her paper at the conference and will receive up to $750 to offset expenses as well as gratis registration to the meeting. The winners will be awarded a calligraphed certificate at a special prize ceremony at the meeting. Papers must be singly authored to be eligible for consideration. To qualify, authors must be students in good standing who have not received their PhDs at the time of submission. In submitting their work for publication, authors are asked to consider the SIAM journals. Submissions must be received by SIAM on or before March 15, 1992. Submissions can be sent by regular mail or fax. Each submission must include (1) an extended abstract NOT LONGER THAN 5 PAGES (including bibliography), double-spaced, in English; (2) the signature of the author on the submission; (3) a statement by the student's faculty advisor that the paper has been prepared by the author indicated and that the author is a student in good standing; and (4) a short biography of the student. It is not necessary to send the full paper. Each submission must also include a letter of recommendation from the student's advisor or the department chair. Submissions will be judged on the basis of originality, applicability, and clarity of exposition. The winners will be notified by May 30, 1992.

The stamp (brown,40 Kop.) bears the portrait of Lyapunov and the following equation: ((omega-squared)/2)(x-squared + y-squared) + f.rho.integral of d tao-prime/D = const. ("f.rho" may indeed be "fp",the formula is handwritten). Any idea what the formula is?
