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.

FREQUENCY 5)

The number of oscillations per unit of time in a periodic phenomenon

In complex nonlinear systems, the presence of various simultaneous processes accounts for the existence of superimposed periodic phenomena and a globally mixed up behavioral curve, wherein the specific frequencies corresponding to the different processes are embedded.

In these cases, the global aspect of the process frequencies appears as irregular.

Complex curves can be studied through frequency (or harmonic, or spectral, or FOURIER) analysis, but their decomposition is based either on pre-determined hypotheses, or on pure mathematical technique and, as such, the results are sometimes questionable.

Incommensurability of merely three frequencies in a nonlinear dynamic system is a basic factor for the onset of chaotic behavior.
