Chaos and Order in Nature (Springer series in synergetics)

Chaos and Order in Nature (Springer series in synergetics) Lowest used price: $14.91
List price: $52.95
Author: H. Haken

This book contains the invited papers of an international symposium on synergetics; which was held at Schlol3 Elmau, Bavaria, FRG, April 27 to May 1, 1981. At our previous meetings on synergetics the self-organized formation of structures in quite different disciplines stood in the foreground of our interest. More recently it has turned out that phenomena characterized by the word "chaos" appear in various disciplines, and again far-reaching analogies in the behavior of quite different systems become visible. Therefore this meeting was devoted not only to problems connected with the occurrence of ordered structures but also to most recent results obtained in the study of chaotic motion. In the strict mathematical sense we are dealing here with deterministic chaos, i. e. , irregular motion described by deter­ ministic equations. While in this relatively young fieJd of research computer ex­ periments and computer simulations predominated in the past, there now seems to be a change of trend, namely to study certain regular features of chaos by analytical metbods. I think considerable progress has been achieved in this respect quite recently. This theoretical work is paralleled by a number of very beautiful experi­ ments in different fields, e. g. , fluid dynamics, solid-state physics, and chemistry. For the first time at this kind of meeting we have included plasma physics, which presents a number of most fascinating problems with respect to instabilities, formation of structures, and related phenomena.

There are some types of complex systems that are built like clockwork, with well-defined parts that interact in well-defined ways, so that the action of the whole can be precisely analyzed and anticipated with accuracy and precision. Some systems are not themselves so well-defined, but they can be modeled in ways that are like trained pilots in well-built planes, or electrolyte balance in healthy humans. But there are many systems for which that is not true; and among them are many whose understanding and control we would value. For example, the model for the trained pilot above fails exactly where the pilot is being most human; that is, where he is exercising the highest levels of judgment, or where he is learning and adapting to new conditions. Again, sometimes the kinds of complexity do not lead to easily analyzable models at all; here we might include most economic systems, in all forms of societies. There are several factors that seem to contribute to systems being hard to model, understand, or control. The human participants may act in ways that are so variable or so rich or so interactive that the only adequate model of the system would be the entire system itself, so to speak. This is probably the case in true long term systems involving people learning and growing up in a changing society.

This volume consists of a selection of papers presented at the International Conference on Applied General Systems Research: Recent Developments and Trends which was held on the campus of the State University of New York at Binghamton in August 15-19, 1977, under the sponsorship of the Special Panel on Systems Science of the NATO Scientific Affairs Division. General systems research is a fairly new field which has been developing in the course of the last two or three decades. In my op~n10n, it can be best described as a movement which involves the study of all structural and context independent aspects of problem solving. As such, it is cross-disciplinary in nature and, in this sense, it might seem similar to mathematics. There is a consid­ erable difference, however, between the two. While pure mathe­ matics is basically oriented to the development of various axiomatic theories, regardless of whether or not they have any real world meaning, applied mathematics explores the applicability of some of these theories as potentially useful methodological tools in various problem areas. General systems research, in contrast with applied mathematics, is problem oriented rather than tool oriented. As such, it tries to develop genuine methods for solving systems problems, i. e. , structural type and context in­ dependent problems. The term "genuine method" is used here to refer to a method which adjusts to the problem rather than re­ quiring that the problem be adjusted to make the method applicable.

"Evolution of Dynamical Structures in Complex Systems" is dedicated to the founder of synergetics, Hermann Haken, on the occasion of his 65th birthday. This volume is an attempt to gather together and review the new results and de­ velopments achieved by researchers from various fields during the last few years. The contents bear witness to the great success in the development of general approaches to synergetic systems as well as remarkable progress in the more tra­ ditional fields of synergetics such as lasers and nonlinear optics, hydrodynamics, condensed matter physics, biology, and sociology. Since their inception, the concepts of synergetics and rigorous mathematical theories have been extended to other scientific disciplines such as medicine, artifi­ cial intelligence and synergetic computers, and psychology. Here too, these ideas have yielded new insights, raised unexpected questions and produced innovations in both theoretical and experimental projects. The conception of self-organization, the central theme of Hermann Haken' s scientific work, has stimulated epistemo­ logical studies that draw relations between synergetics and the German romantic "Naturphilosophie". It is fascinating to observe how these intuitive notions of self-organization, etc., have now evolved into a precise and holistic scientific comprehension of synergetic systems. We express our deep gratitude to Dr. Angela Lahee from Springer-Verlag for her valuable help during the preparation of this book. Stuttgart R. Frjedrjch March 1992 .4..

Elimination of Risk in Systems: Practical Principles for Eliminating and Reducing Risk in Complex Systems

Elimination of Risk in Systems: Practical Principles for Eliminating and Reducing Risk in Complex Systems List price: $34.95
Author: James Bradley

This book introduces a new set of practical principles for eliminating and reducing risk in any kind of system, whether financial or non financial and including engineering, computer and business systems -- and even military systems.

Although these new principle have come from research into risk in engineering and computer systems, surprisingly, they also resolve an old dispute in the investment arena, between the academic theorists who use the beta measure of risk and the followers of the ideas of the late Benjamin Graham, and his famous disciple, Warren Buffett. Each side is well known for castigating the theories and ideas of the other, with seemingly little common ground.

The new risk principles, and principles for eliminating risk, show clearly that both sides in this famous dispute are right, for the new principles bridge the gap between the two. They show that the beta-theory proponents simply had failed to develop their theory far enough -- their risk measure in particular -- to include risk elimination possibilities.

At the heart of the new theory of risk in systems are two ideas: first, the idea of extending the risk measure to include average system output loss with respect to the best-case system output, and second, the idea of eliminating those output losses with respect to the best case, thus preserving the benefit of running the risk.

The author presents the new principles along with many practical and numerical examples, and the essential ideas are clearly explained. Nevertheless, if you examine the material closely, you will find that it will withstand a rigorous analysis.

There are some elementary mathematical relationships in the book, but because their meaning is also well explained in words, and reinforced by practical examples, these can often be skipped. The intent is to enable you to grasp the ideas and concepts well enough to enable you to put them to practical use, in whatever your field of endeavor, anything from spacecraft engineering, to computer systems design, to investment management.
