A modelling of the soil structure and surface roughness by means of the fractal growth concepts is presented. Two parameters are used to control the model: the fragmentation dimension, Df, and the maximum mass of the deposited aggregates, Mmax. The fragmentation dimension is related to the...

Models which consider behavioral aspects of the investors have attracted increasing interest in the Finance and Econophysics literature in the last years. Different behavioral profiles (imitation, anti-imitation, indifference) were proposed for the investors, which take their decision based on...

We propose a new method to determine the multi-affine fractal exponents based on a generalization of the roughness concept. For synthetic multi-affine fractal profiles with exactly known exponents, we show that the results obtained in this method are more accurate than the results obtained with...

Cellular automata (CA) are discrete, spatially homogeneous, locally interacting dynamical systems of very simple construction, but which exhibit a rich intrinsic behavior. CA can, even starting from disordered initial configurations, evolve into ordered states with complex structures...
