Download or read book The Evolution of Conceptual Modeling written by Roland Kaschek and published by Springer Science & Business Media. This book was released on 2011-02-04 with total page 348 pages. Available in PDF, EPUB and Kindle. Book excerpt: Conceptual modeling represents a recent approach to creating knowledge. It has emerged in response to the computer revolution, which started in the middle of the 20th century. Computers, in the meantime, have become a major knowledge media. Conceptual modeling provides an answer to the difficulties experienced throughout the development of computer applications and aims at creating effective, reasonably priced, and sharable knowledge about using computers in business. Moreover, it has become evident that conceptual modeling has the potential to exceed the boundaries of business and computer usage. This state-of-the-art survey originates from the International Seminar on the Evolution of Conceptual Modeling, held in Dagstuhl Castle, Germany, in April 2008. The major objective of this seminar was to look into conceptual modeling from a historical perspective with a view towards the future of conceptual modeling and to achieve a better understanding of conceptual modeling issues in several different domains of discourse, going beyond individual (modeling) projects. The book contains 14 chapters. These were carefully selected during two rounds of reviewing and improvement from 26 presentations at the seminar and are preceded by a detailed preface providing general insights into the field of conceptual modeling that are not necessarily discussed in any of the chapters but nevertheless aid in conceptualizing the inner structure and coherence of the field. The chapters are grouped into the following three thematic sections: the evolution of conceptual modeling techniques; the extension of conceptual modeling to a service-oriented, peer-to-peer, or Web context; and new directions for conceptual modeling.

Download or read book Identifiability of Parametric Models written by E. Walter and published by Elsevier. This book was released on 2014-05-23 with total page 132 pages. Available in PDF, EPUB and Kindle. Book excerpt: Identifiability of Parametric Models provides a comprehensive presentation of identifiability. This book is divided into 11 chapters. Chapter 1 reviews the basic methods for structural identifiability testing. The methods that deal with large-scale models and propose conjectures on global identifiability are considered in Chapter 2, while the problems of initial model selection and generating the set of models that have the exact same input-output behavior are evaluated in Chapter 3. Chapters 4 and 5 cover nonlinear models. The relations between identifiability and the well-posedness of the estimation problem are analyzed in Chapter 6, followed by a description of the algebraic manipulations required for testing a model for structural controllability, observability, identifiability, or distinguishability in chapter 7. The rest of the chapters are devoted to the relations between identifiability and parameter uncertainty. This publication is beneficial to students and researchers aiming to acquire knowledge of the identifiability of parametric models.

Download or read book RCS linear Discrete Actuator Study written by Thomas Bailey and published by . This book was released on 1988 with total page 318 pages. Available in PDF, EPUB and Kindle. Book excerpt: The objective of the program was to develop the technology and demonstrate the use of linear discrete actuators combined with a rocket control system (RCS) to control the large angle slew and fine pointing/tracking of a simulated large flexible space structure. The linear actuators included proof-mass actuators, and a hub torquer to simulate a control moment gyro or reaction wheel actuator. The demonstration used the CSDL/AFAL ground test facility located at CSDL, Inc. The facility comprises the flexible test structure and actuators which are mounted on a low-friction, air-bearing table, and associated test instrumentation. The combined linear discrete and RCS actuators demonstrated significantly improved fine pointing/tracking a vibration suppression capability relative to the uses of the RCS alone. Keywords include: Linear discrete actuators, Proof-mass actuators, and Flexible structure control. (rh).

Book excerpt: This volume is the second of the three volume publication containing the proceedings of the 1989 International Symposium on the Mathemat ical Theory of Networks and Systems (MTNS-89), which was held in Amsterdam, The Netherlands, June 19-23, 1989 The International Symposia MTNS focus attention on problems from system and control theory, circuit theory and signal processing, which, in general, require application of sophisticated mathematical tools, such as from function and operator theory, linear algebra and matrix theory, differential and algebraic geometry. The interaction between advanced mathematical methods and practical engineering problems of circuits, systems and control, which is typical for MTNS, turns out to be most effective and is, as these proceedings show, a continuing source of exciting advances. The second volume contains invited papers and a large selection of other symposium presentations in the vast area of robust and nonlinear control. Modern developments in robust control and H-infinity theory, for finite as well as for infinite dimensional systems, are presented. A large part of the volume is devoted to nonlinear control. Special atten tion is paid to problems in robotics. Also the general theory of nonlinear and infinite dimensional systems is discussed. A couple of papers deal with problems of stochastic control and filterina. vi Preface The titles of the two other volumes are: Realization and Modelling in System Theory (volume 1) and Signal Processing, Scattering and Operator Theory, and Numerical Methods (volume 3).

Download or read book Artificial Intelligence in Real Time Control written by M. G. Rodd and published by Elsevier. This book was released on 2014-05-23 with total page 159 pages. Available in PDF, EPUB and Kindle. Book excerpt: Artificial Intelligence in Real-Time Control documents the proceedings of the IFAC Workshop held in Clyne Castle, Swansea, UK, 21-23 September 1988. It includes two keynote addresses that discussed architectural issues for expert systems in real-time control; the problem of representing knowledge and reasoning; and the problems encountered in obtaining such information. Other papers contained in these proceedings are representative of the major research bodies active throughout the world in the application of AI techniques in real-time control, although it was inevitable that a Europe-based conference would highlight the work of the European groups. While AI is clearly still in the process of establishing itself, it is undoubtedly a major new area of engineering endeavor. Practical experience is still relatively limited, and many of the results discussed at this event were obtained through simulation or, in a few cases, from reduced practical experience. The importance, though, lies in the fact that many countries are pouring extensive resources into the attempt to control difficult processes by using AI techniques. The wide cross section of interest was demonstrated by the fact that many diverse industries were represented at the workshop—ranging from power-systems control to telecommunications, and into the steel industry.

Download or read book Essays on the Economics of Migratory Fish Stocks written by Ragnar Arnason and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 198 pages. Available in PDF, EPUB and Kindle. Book excerpt: Following the publication of seminal papers by professors H. S. Gordon in 1954 and A. D. Scott in 1955, active research has led to rapid progress in our understanding of the economics of fisheries. Fishing, however, is a complicated activity involving intricate interactions between man-made fishing capital and naturally produced fish stocks in an inherently dynamic and stochastic setting. Consequently, in spite of significant advances, important sections of fisheries economics remain largely unexplored. One such area is the economics of migratory fish stocks. In 1985, the editors of this volume embarked on a research project concerned with the optimal utilization of common Nordic fish stocks. A fundamental feature of some of the most important of these fish stocks, such as the Atlanto-Scandian herring and the Icelandic capelin, is their migratory behaviour. Not only do the migrations continuously alter the economic conditions for harvesting these species. They also result in the periodical transfer of stock concentrations from one exclusive fisheries jurisdictions to another. It was readily apparent that this behaviour constituted a crucial determinant of the appropriate harvesting pattern of these stocks. More importantly, however, migrations are by no means a unique feature of Nordic fish stocks. In fact, it appears that migratory behaviour is exhibited, albeit in varying degrees, by all species of fish. It therefore stands to reason that migrations constitute an important aspect of the economics of fisheries in general.
