International Encyclopedia of Systems and Cybernetics

2nd Edition, as published by Charles François 2004 Presented by the Bertalanffy Center for the Study of Systems Science Vienna for public access.

About

The International Encyclopedia of Systems and Cybernetics was first edited and published by the system scientist Charles François in 1997. The online version that is provided here was based on the 2nd edition in 2004. It was uploaded and gifted to the center by ASC president Michael Lissack in 2019; the BCSSS purchased the rights for the re-publication of this volume in 200?. In 2018, the original editor expressed his wish to pass on the stewardship over the maintenance and further development of the encyclopedia to the Bertalanffy Center. In the future, the BCSSS seeks to further develop the encyclopedia by open collaboration within the systems sciences. Until the center has found and been able to implement an adequate technical solution for this, the static website is made accessible for the benefit of public scholarship and education.

MODE 2)5)

1. A specified pattern of periodic or vibratory movement.

Simple oscillators have only one mode of periodicity.

Modes are related to frequencies in oscillations.

D. RUELLE writes: "If only one mode is excited, we observe periodic oscillations. If various modes are excited, the fluid's movement becomes irregular and, when many modes are excited it becomes turbulent" (1991, p. 71).

In general, turbulence implies chaotic determinism.

2. The value occuring most frequently in a series of statistical observations, or probability distribution.

A distribution may present two or more very frequent occurences. It is then called bi- or multi-modal. This may be the case for instance in Markov chains or Markovian systems and correspond to various preferred states, for example in a population distribution. This was interestingly developed by W.R. ASHBY (1956, p.166-7 and 225-29).
