Spectral Analysis (An Introduction to Complex Systems in Environment)
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 ...

Plant eco-physiology for crop models
Description :

This section presents an overview of plant physiology concepts involved in crop modelling.

Thermal Time normalization - The thermal time normalization allows comparing plant growth on both organogenesis (organ numbering) and development (organ size) aspects.
