โœฆ Synopsis

Using a numerical approach based on parallel processing, the time evolution of a growing surface has been studied in the framework of the Kardar-Parisi-Zhang model. The growth term has been introduced as noise with a Gaussian distribution, a nonzero mean value and spatial Gaussian correlations. The procedure allowed us to demonstrate that both surface width and relative porosity evolve towards a steady state. The short-time behaviour and the dependence on the specimen dimension of the asymptotic value of these quantities have been investigated.

New models for multiphasic growth are presented. They are illustrated by analysis of brain growth in humans and chimpanzees, and the results are used to test the hypothesis of evolution by proportional growth prolongation: that all descendant growth phases are extended by the same factor while each

A computer model, named BOSCO 1, is described aimed to simulate evolution and growth of a wood composed of one single species of trees. The main computed variables are the number and size (wood volume) of the trees. The effects of climate and accidents are taken into account. The model is written in
