The Prize may be awarded for an outstanding scientific achievement or for lifetime contribution. The Prize is awarded every three years at an appropriate ILAS meeting, as decided upon by the ILAS Executive Board. In any year in which a Prize is awarded, there may be more than one recipient, within the discretion of the Board. The first prize was awarded in 1993 to Miroslav Fiedler, Shmuel Friedland and Israel Gohberg. Procedure for determining the winner ------------------------------------ A Prize Committee is established by the ILAS President upon the recommendation of the ILAS Executive Board. The Committee solicits nominations from members of the linear algebra community of people of outstanding achievement in the subject and the Committee makes recommendations to the ILAS Executive Board, which then makes the award. (There shall be no restrictions on whom shall receive the Prize based on sex, race, national origin, age or the time since the recipient took his or her last academic degree). The recipient is notified at least two months prior to the ILAS meeting at which the Prize is to be presented and is also invited to give a talk at that meeting. Nature of the Prize ------------------------------------ The Prize consists of a plaque and a certificate containing the citation. The Executive Board may also decide to make a cash award to the recipient and/or make a contribution towards the expenses incurred in attending the award ceremony. Funding ------------------------------------ The funding for the Prize comes from the interest accruing on a large donation made to ILAS by Hans Schneider and a number of small contributions from other people. Next (second) Award ------------------------------------ The second Prize will be awarded at the ILAS conference in Chemnitz, Germany, in August 1993. The Prize Committee consists of: Daniel Hershkowitz (chairman) Richard A. Brualdi Shmuel Friedland Thomas J. Laffey Peter Lancaster and Hans Schneider (ILAS President, ex-officio). Nominations ------------------------------------ Nominations are now being solicited from members of ILAS and the linear algebra community in general of distinguished individuals judged worthy of consideration for the Prize. In nominating a person, the nominator should include a brief biographical sketch together with a statement explaining why the nominee is considered worthy of the Prize. The nominator should include references to the publications or other contributions of the nominee which are considered most significant in making this assessment. Nominations should be sent before October 20, 1995, to Daniel Hershkowitz Mathematics Department Technion Haifa 32000 Israel e-mail: hershkow@tx.technion.ac.il | *.*.*.*.*.*.*.*.*.*.*.*.*.*.*.*.*.*.*.*.*.*.*.*.*.*.*.*.*.*.*.*.*.*.*.*.*.*.** Contributed by: Sanjay Lall WWW CONTROL ENGINEERING LIBRARY =============================== New Mirror Site =============== The WWW Virtual Library on Systems and Control is now mirrored at Caltech, so that access from North America will be much faster than previously.

Curtain, Mathematics Institute, University of Groningen, the Netherlands and Hans Zwart, Faculty of Applied Mathematics, University of Twente, the Netherlands Infinite-dimensional systems is now an established area of research. Given the recent trend in systems theory and in applications towards a synthesis of time- and frequency-domain methods, there is a need for an introductory text which treats both state-space and frequency-domain aspects in an integrated fashion. The authors' primary aim is to write an introductory textbook for a course on infinite-dimensional linear systems. An important consideration by the authors is that their book should be accessible to graduate engineers and mathematicians with a minimal background in functional analysis; for the majority of students, this would be their only acquaintance with infinite-dimensional systems. Consequently, all the mathematical background is summarized in an extensive appendix. The aim of the book is to enable the students to apply the theory to partial differential and delay systems commonly met in the applications. This is facilitated by including several concrete examples, both in the text and in the problem sets at the end of each chapter. The origin of this book is the authors' lecture notes that they wrote and used in a course in Infinite- Dimensional Linear Systems Theory. What sets this book apart from the competition is that it is the only one to integrate the frequency domain and state-space approaches, and to include over 250 problems based on the theory and applications; in this respect, it is unique.

Brualdi and Bryan L. Shader Cambridge Tracts in Mathematics, No. 116 xii + 298, ISBN 0-521-48296-8 Cambridge University Press. The list price of the book is $49.95 but it will be offered in Cambridge's fall catalog at a 20% discount. A description of the book follows. ************ The sign-solvability of a linear system implies that the signs of the entries of the solution (or at least some of the entries) are determined solely on the basis of the signs of the coefficients of the system. That it might be worthwhile and possible to investigate such linear systems was recognized by Samuelson in his classic book Foundations of Economic Analysis. Sign-solvability is part of a larger study which seeks to study and understand the special circumstances under which an algebraic, analytic or geometric property of a matrix can be determined from the combinatorial arrangement of the positive, negative and zero elements of the matrix. These are thus properties shared by all members of a qualitative class of matrices. Several classes of matrices arise in this way, notably sign-nonsingular matrices, L-matrices, S-matrices, and sign-stable matrices. The essential idea of a sign-nonsingular matrix arose in a different context in the key 1963 paper Dimer statistics and place transitions by P.W. Kastelyn. The large and diffuse body of literature connected with sign-solvability is presented as a coherent whole for the first time in this book. Results in the literature are presented in a new and organized way with many new connections established and with many new results and proofs. One of the features of this book is that algorithms that are implicit in many of the proofs have been explicitly described and their complexity has been commented on. The book is intended primarily for researchers in combinatorics and linear algebra but it should be of interest to theoretical computer scientists, economists, physicists, chemists, engineers and other scientists. It should also be of interest to those who would like to see the beautiful interplay that it affords between combinatorics (especially, graph theory) and linear algebra. The book is self-contained but it does assume that the reader is familiar with elementary linear algebra and has been introduced to some aspects of graph theory and combinatorial matrix theory. *.*.*.*.*.*.*.*.*.*.*.*.*.*.*.*.*.*.*.*.*.*.*.*.*.*.*.*.*.*.*.*.*.*.*.*.*.*.** Contributed by: Nirmal Kumar Bose Neural Network Fundamentals with Graphs, Algorithms, and Applications, by N.K.

Gallager, Massachusetts Institute of Technology DISCRETE STOCHASTIC PROCESSES helps the reader develop the understanding and intuition necessary to apply stochastic process theory in engineering, science and operations research. The book approaches the subject via many simple examples which build insight into the structure of stochastic processes and the general effect of these phenomena in real systems. The book presents mathematical ideas without recourse to measure theory, using only minimal mathematical analysis. In the proofs and explanations, clarity is favored over formal rigor, and simplicity over generality.

This book provides a careful treatment of the theory of algebraic Riccati equations. It consists of four parts: the first part is a comprehensive account of necessary background material in matrix theory including careful accounts of recent developments involving indefinite scalar products and rational matrix functions. The second and third parts form the core of the book and concern the solutions of algebraic Riccati equations arising from continuous and discrete systems. The geometric theory and iterative analysis are both developed in detail. The last part of the book is an exciting collection of eight problem areas in which algebraic Riccati equations play a crucial role. These applications range from introductions to the classical linear quadratic regulator problems and the discrete Kalman filter to modern developments in H-infinity control and total least squares methods.

For example, a particular user might wish to gain network access through any number of different ports or connection media. Likewise, a network service might reside on one of many possible processors. Under such a scenario, where both users and network services change location, the distinction between the ``fixed'' and ``mobile'' network blurs; all networks are mobile networks. The overall costs of maintaining accurate location records are at present only poorly understood. However, recent work indicates that simply for telephone traffic, the excess network signaling load expense would be much larger than that required for classical fixed traffic. If migrant services and databases are included, the aggregate signaling load can only be greater. In addition, for wireless systems, the relevant signaling events require use of radio channels and such use must be minimized owing to the scarcity of bandwidth. Thus, either from the standpoint of modifying existing fixed network signaling structures or designing wireless network paging/registration strategies, it is important to understand, quantify and devise methods for handling the impact of location uncertainty on signaling. SCOPE: This special issue will concentrate on the problems associated with acquiring and maintaining mobile unit location information in the wireless environment. A representative sampling of topics is provided below: - Mobility modeling - Location prediction - Empirical measurements for user profiles - Location tracking and mobile network topology - Location tracking for handoff - Paging/Registration cost minimization - Multi-unit paging techniques - Performance Analysis of location management strategies PUBLICATION SCHEDULE: MANUSCRIPT DUE: October 1, 1995 ACCEPTANCE NOTIFICATION: January 1, 1996 FINAL MANUSCRIPT DUE: March 1 1996 Publication Date: Summer 1996.

By a logic-based switching controller is meant a controller whose subsystems include not only familiar dynamical components such as integrators, summers, gains, etc., but a nontrivial logical component as well. More often than not the predominately logical component within such a system is called a supervisor, a mode changer, a gain scheduler, a reference governor or something similar. Within the past few years there has been a growing interest in determining what might be gained by utilizing hybrid controllers of this type. Toward this end detailed analyses, simulation studies and laboratory experiments of such systems have been initiated in a variety of disciplines including adaptive control, gain scheduling, control of nonholonomic systems, motion control, and the control of saturation constrained systems. The primary purpose of the workshop is to bring together a small number of specialists working within the area for the purpose of crystallizing concepts, problem formulations, and approaches. The workshop will be centered around approximately seventeen consecutive, 45 minute presentations given over a two day period. We are encouraging the attendance of individuals who are either already working in the area or who desire to learn more about opportunities for research in the area. Block Island is about 70 minutes by ferry off the coast of Rhode Island. The island can also be reached by air. Because of limited air and ferry connections, participants should plan to spend the nights of September 29, 30, and October 1 on the island. Those traveling from the west coast may prefer to spend the night of the 28th enroute. On the other hand is not difficult to travel from Block Island to any destination in North America within a single day . Partial List of Speakers: M.
