Invasion Percolation Between two Sites
A. D. Araujo, T. F. Vasconcelos, A. A. Moreira +2
We investigate the process of invasion percolation between two sites (injection and extraction sites) separated by a distance r in two-dimensional lattices of size L. Our results f…
The Complex Topology of Chemical Plants
J. S. Andrade, D. M. Bezerra, J. Ribeiro Filho +1
We show that flowsheets of oil refineries can be associated to complex network topologies that are scale-free, display small-world effect and possess hierarchical organization. The…
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…
Precise calculation of the threshold of various directed percolation models on a square lattice
Danyel J. B. Soares, Jose S. Andrade, Hans J. Herrmann
Using Monte Carlo simulations on different system sizes we determine with high precision the critical thresholds of two families of directed percolation models on a square lattice.…
