The distribution of local fluxes in porous media
Ascânio D. Araújo, Wagner B. Bastos, José S. Andrade +1
We study the distributions of channel openings, local fluxes, and velocities in a two-dimensional random medium of non-overlapping disks. We present theoretical arguments supported…
Renormalizing Sznajd model on complex networks taking into account the effects of growth mechanisms
M. C. Gonzalez, A. O. Sousa, H. J. Herrmann
We present a renormalization approach to solve the Sznajd opinion formation model on complex networks. For the case of two opinions, we present an expression of the probability of…
Model of mobile agents for sexual interactions networks
M. C. Gonzalez, P. G. Lind, H. J. Herrmann
We present a novel model to simulate real social networks of complex interactions, based in a granular system of colliding particles (agents). The network is build by keeping track…
Random bearings and their stability
R. Mahmoodi Baram, H. J. Herrmann
Self-similar space-filling bearings have been proposed some time ago as models for the motion of tectonic plates and appearance of seismic gaps. These models have two features whic…
Scaling behavior of fragment shapes
F. Kun, F. K. Wittel, H. J. Herrmann +2
We present an experimental and theoretical study of the shape of fragments generated by explosive and impact loading of closed shells. Based on high speed imaging, we have determin…
Aeolian transport layer
M. P. Almeida, J. S. Andrade, H. J. Herrmann
We investigate the airborne transport of particles on a granular surface by the saltation mechanism through numerical simulation of particle motion coupled with turbulent flow. We…
