Survival-extinction phase transition in a bit-string population with mutation
Kathia M. Fehsenfeld, Ronald Dickman, Americo T. Bernardes
A bit-string model for the evolution of a population of haploid organisms, subject to competition, reproduction with mutation and selection is studied, using mean field theory and…
Election results and the Sznajd model on Barabasi network
A. T. Bernardes, D. Stauffer, J. Kertesz
The network of Barabasi and Albert, a preferential growth model where a new node is linked to the old ones with a probability proportional to their connectivity, is applied to Braz…
Failure regime in (1+1) dimensions in fibrous materials
I. L. Menezes-Sobrinho, A. T. Bernardes, J. G. Moreira
In this paper, we introduce a model for fracture in fibrous materials that takes into account the rupture height of the fibers, in contrast with previous models. Thus, we obtain th…
Scaling behaviour in the fracture of fibrous materials
I. L. Menezes-Sobrinho, J. G. Moreira, A. T. Bernardes
We study the existence of distinct failure regimes in a model for fracture in fibrous materials. We simulate a bundle of parallel fibers under uniaxial static load and observe two…
Immunization and Aging: a Learning Process in the Immune Network
Rita Maria Zorzenon dos Santos, Americo T. Bernardes
The immune system can be thought as a complex network of different interacting elements. A cellular automaton, defined in shape-space, was recently shown to exhibit self-regulation…
