Cellular Models for River Networks
G. Caldarelli
A cellular model introduced for the evolution of the fluvial landscape is revisited using extensive numerical and scaling analyses. The basic network shapes and their recurrence es…
Fractal Growth from Local Instabilities
Raffaele Cafiero, Guido Caldarelli
We study, both with numerical simulations and theoretical methods, a cellular automata model for continuum equations describing growth processes in the presence of an external flux…
A Numerical Study on the Evolution of Portfolio Rules: Is CAPM Fit for Nasdaq?
G. Caldarelli, M. Piccioni, E. Sciubba
In this paper we test computationally the performance of CAPM in an evolutionary setting. In particular we study the stability of wealth distribution in a financial market where so…
Damaging and Cracks in Thin Mud Layers
Raffaele Cafiero, Guido Caldarelli, Andrea Gabrielli
We present a detailed study of a two-dimensional minimal lattice model for the description of mud cracking in the limit of extremely thin layers. In this model each bond of the lat…
Roughness of fracture surfaces
Andrea Parisi, Guido Caldarelli, Luciano Pietronero
We study the fracture surface of three dimensional samples through a model for quasi-static fractures known as Born Model. We find for the roughness exponent a value of 0.5 expecte…
