  • Branch distribution in diffusion-limited aggregation: a maximum entropy approach 

    Pastor Satorras, Romualdo; Wagensberg, Jorge (1996-02-15)
    Article
    Restricted access - publisher's policy
    A new approach to the branching structure of diffusion-limited aggregation (DLA) clusters is proposed, in which the stress is laid not on the (traditionally used) order of the branches, but on their mass. The branch ...
  • Monte Carlo simulation of an ecosystem : a matching between two levels of observation 

    Giró Roca, Antoni; Padro Cardenas, Joan Angel; Valls Ribas, Joaquim; Wagensberg, Jorge (1984)
    External research report
    Open Access
    A Monte Carlo computer simulation is designed in order to describe the evolution of an ecosystem under imposed environmental conditions of energy. Some preliminar results of a simple situation show a suggestive matching ...
  • The maximum entropy principle and the nature of fractals 

    Pastor Satorras, Romualdo; Wagensberg, Jorge (1998-06-19)
    Article
    Open Access
    We apply the Principle of Maximum Entropy to the study of a general class of deterministic fractal sets. The scaling laws peculiar to these objects are accounted for by means of a constraint concerning the average content ...
