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.

STOCHASTIC RESONANCE 2)

The amplification of a specific signal through a random noise.

This phenomenon has been described by the Italian physicists R. BENZI, A. SUTERA and A. VULPIANI (see K.S. BROWN, 1996, p.28-31).

In some cases, the very small impact of the random noise on the signal that may become significant as a trigger for a specific process, is sufficient to push the signal over the brink of effectiveness. This model has been used by the Italian physicists as a possible explanation for the periodic ushering of ice ages. Other examples are also known. A similar effect could explain the sudden magnification from quite small transactions in the stock market into a generalized panic. In all these cases, of course, the affected system must be close to some instability threshold. Still another hypothetical possible case would be a massive change in the oceanic waters circulation patterns, for example as a result of partial desalinization of superficial waters by a massive flow of nonsalted water due to partial or total deglaciation of the poles.

As stated by R. VALLÉE, noise can be an excellent structure displayer, even at macroscopic level (1990, p.55).

Stochastic resonance could conceivably used to produce some trigger effects, or explain some whose direct cause is not clear. For more, see P. Mc CLINTOCK and D E. LUCHINSKY (1999, p.37 -39)
