81. Passive And Active Vibration Isolation Systems - Theory The passive vibration isolation system consists of a spring and damper (dashpot) The active system uses also accelerometers and electromagnetic drivers http://physics.nad.ru/Physics/English/spri_txt.htm

PASSIVE AND ACTIVE VIBRATION ISOLATION SYSTEMS Vibrations accompany us everywhere and in most cases these vibrations are undesirable. First of all we can mention the vibration of cars and carriages, motors and machine tools, oil and gas platforms, buildings and constructions in a zone of seismic activity, undesirable vibrations of laboratory tables (especially optical), setups, etc. In all these cases an object has to be isolated from the source of vibrations. Despite of all constructional distinctions the essence of vibration isolation systems are identical. The passive vibration isolation system consists of a spring and damper (dash-pot). The spring is intended to soften vibrations and pushes, and damper has to terminate the oscillation which is excited in system. The active system uses also accelerometers and electromagnetic drivers which allows higher degree of vibration isolation to be achieved. Let us consider the work of passive vibration isolation system by the example of a suspension bracket of the automobile. In any suspension bracket there are elastic elements, which soften pushes and impacts of the road. Other not less important element of a suspension bracket is the shock-absorber the device which is intended to terminate excited the oscillation. Many drivers think that shock-absorbers is only the means to maintain comfort. Actually functions of this element of a suspension bracket are directly connected to maintenance of contact of a wheel with road, i.e. with controllability of the automobile and traffic safety.

Bio-Mimetic Control Research Center Japanese RIKEN (The Institute of Physical and Chemical Research) at Nagoya 2271-130, Anagahora, Shimoshidami, Moriyama-ku Nagoya, 463-0003 JAPAN Our snake-like swimming robot using an artificial muscle is introduced by mass media. (March 4, 2005) General Invitation of Postdoctoral Researcher and Technical Stafa BMC Access Guide The aim of research into bio-mimetic control is to mimic the highly sophisticated control functions of the living systems in order to create flexible, precise and reliable engineering systems. The Bio-Mimetic Control Research Center (BMC) of RIKEN was established in October 1993 as a two-term project for the purpose of carrying out research in this highly interdisciplinary endeavor. The second term of research, begun in October 2001, will further promote work from such aspects as system control theory, robotics, biological control and sensory mechanisms. BMC is located in the Nagoya area, itself situated in an area of Japan possessed of a long tradition in such highly sophisticated manufacturing industries as aircraft and automobile manufacture. It is expected that the advanced research potential possessed by RIKEN fused with the special characteristics of the region will bear much fruit toward advancing the aims of bio-mimetic research.

Feedback Requested INTRODUCTION What This Is This is a list, with reviews, of suggested books, periodicals, television shows and computer programs for a classroom curriculum or individual study in cybernetics and systems theory. It does not (yet) include a course plan, glossary, or extended bibliography. I was asked to write this by some teachers who received a copy of class notes I prepared for a course in "Understanding Whole Systems" sixteen years ago at the University of California at Santa Cruz. They asked how I would revise it based on what I know today. This document answers that question.

Research areas The Systems Theory group has been active since 1974. Research at ISIB-information (previously LADSEB) can be framed in five areas: realization and approximation of stochastic systems, stochastic control, nonlinear filtering, mathematical finance, modelling and performance analysis of communication protocols for industrial applications. Stochastic realization Stochastic control : approximation techniques have been studied for problems of stochastic control with partial observations. In particular, using transformation measure techniques, there have been obtained approximate problems whose almost optimal solutions are in fact almost optimal for the original problem as well, with error arbitrar ily small (see e.g. Bensoussan and Runggaldier [1987], Di Masi and Runggaldier [1987], Runggaldier and Zane [1991], Runggaldier and Stettner [1991]. Recently, the connections between piecewise linear control systems and adaptive controllers have been studied, with the pourpose of showing the relevance of adaptive techniques for the control of nonlinear systems. In Albertini and Runggaldier [1988] Fleming's logarithmic transform has been extended to the discrete case.

Cybernetics and Systems Theory The following links provide general background information on the field of Cybernetics and Systems Theory , an interdisciplinary academic domain. This material was collected and is provided in the context of the Principia Cybernetica Project , but can be consulted independently of the rest of the project. Although there are relatively few research centers and even fewer educational programs devoted to the domain, a lot of activity is going on in between established departments. This is shown by the number of associations , conferences and journals active in the domain. The best way of getting acquainted with the main ideas of cybernetics and systems theory is to read a few of the classic books or papers defining the domain. Some of these books are freely available through our Principia Cybernetica library . Other, specific bibliographic references can be found in the library database of the Department of Medical Cybernetics and AI at the University of Vienna. There also exists more general reference material , including our own Web Dictionary of basic concepts.

What is Systems Theory? Systems Theory : the transdisciplinary study of the abstract organization of phenomena, independent of their substance, type, or spatial or temporal scale of existence. It investigates both the principles common to all complex entities, and the (usually mathematical) models which can be used to describe them. Systems theory was proposed in the 1940's by the biologist Ludwig von Bertalanffy : General Systems Theory, 1968 ), and furthered by Ross Ashby Introduction to Cybernetics The developments of systems theory are diverse (Klir, Facets of Systems Science , 1991), including conceptual foundations and philosophy (e.g. the philosophies of Bunge, Bahm and Laszlo); mathematical modeling and information theory (e.g. the work of Mesarovic and Klir ); and practical applications. Mathematical systems theory arose from the development of isomorphies between the models of electrical circuits and other systems. Applications include engineering, computing, ecology, management, and family psychotherapy. Systems analysis, developed independently of systems theory, applies systems principles to aid a decisIon-maker with problems of identifying, reconstructing, optimizing, and controlling a system (usually a socio-technical organization), while taking into account multiple objectives, constraint s and resources. It aims to specify possible courses of action, together with their risks, costs and benefits. Systems theory is closely connected to

Videotape Systems Theory This page is a brief discussion of videotape systems theory, with some history thrown in for good measure. It may help give you an idea of why early videotape machines sometimes weighed upwards of a ton, and were so finicky. It also gives you some idea of what engineers had to overcome to build a machine the average person could afford! General update 10-19-2004. Email address updated. Status of D-VHS updated. Table of contents A little VTR History. Overview of Magnetic Recording. Special problems of Video Recording. FM Recording. ... In Conclusion. Videotape Systems Theory A Little History first! Any discussion of videotape theory would be incomplete without a brief description of the events that led to the development of the videotape recorder. As you will come to appreciate from reading this tutorial, the development of a practical videotape machine was no trivial task. The videotape machine represents perhaps, the most amazing combination of mechanical and electronic engineering that you will ever find in one device. Indeed, technology developed for the videotape machine also is fundamental to the now ubiqutious computer disk drive as well. The first stirrings that led to a practical videotape machine happened in 1951. This is not to say that there was considerable interest in the concept of recording TV pictures before that. Indeed, ever since Jack Mullin had demonstrated practical magnetic audio recording in this country (Using two tape recorders captured from the Germans during World War II), there was also an interest in recording television pictures. (You will read later why this was so problematic.) In any case, the audio tape recorder had given life to a postwar Ampex Corporation, who was looking for a product to manufacture after it's government contract to manufacture radar components had been canceled.

99. Whole Systems Cybernetics and Systems theory (200+) Principia Cybernetica General Semantics Ludwig von Bertalanffy - General Systems theory http://www.worldtrans.org/whole.html

This area is devoted to the study of whole systems. Nature is a whole system. But also an economy, a family, a company, a community, or many other things, can be looked at as whole systems. A whole system view would include all the factors involved and examine how they relate to each other and how they work as a whole. To deal with a whole system we can't leave anything out as irrelevant. Intuition is as important as rationality, we must address both scientific and artistic approaches, both material and spritual needs, the small as well as the big, what we feel as well as what we think, what we perceive as well as what we imagine. Whole systems are dynamic, they change they move, they develop. Frozen pictures of how things are supposed to be might do us no good, we need to deal with the live systems, whichever surprising directions that might take us in. There is no one authority in the field of whole systems. Luckily nobody has monopolized it by putting it into a standard curriculum defining what it IS. So, we all have the opportunity to discover together what whole systems are about. There is a Whole Systems mailing list for the exploration of whole systems principles, particularly in regards to economic, ecological, sociological and metaphysical transformation of our civilization.
