Cascade phenomenology (An Introduction to Complex Systems in Environment)
Auteur(s)
:
MEZEMATE Yacine, SCHERTZER Daniel
Description
:
Multiplicative cascade processes are frequently used as phenomenological models for the study of a variety of complex systems exhibiting fractal/multifractal behavior. In particular the energy dissipation field of fully developed turbulent flows has been most successfully modeled in such terms, ...

Spectral Analysis (An Introduction to Complex Systems in Environment)
Auteur(s)
:
MEZEMATE Yacine, SCHERTZER Daniel
Description
:
We introduce in this lecture the spectral analysis which is based on the Fourier transform. The main objective of using this can of analysis in our studies is to check the scale invariance propriety of the studied field and also to identify the involved processes. The spectral analysis is widely ...
