On the monotonicity of the critical time in the Constrained-degree percolation model
Charles S. do Amaral, A. P. F. Atman, Bernardo N. B. de Lima
The Constrained-degree percolation model was introduced in [B.N.B. de Lima, R. Sanchis, D.C. dos Santos, V. Sidoravicius, and R. Teodoro, Stoch. Process. Appl. (2020)], where it wa…
Multirange Ising model on the square lattice
Charles S. do Amaral, B. N. B. de Lima, Ronald Dickman +1
We study the Ising model on and show, via numerical simulation, that allowing interactions between spins separated by distances and (two ranges), the criti…
Analysis of the velocity field of granular hopper flow
F. G. R. Magalhães, A. P. F. Atman, J. G. Moreira +1
We report the analysis of radial characteristics of the flow of granular material through a conical hopper. The discharge is simulated for various orifice sizes and hopper opening…
New method to study stochastic growth equations: a cellular automata perspective
T. G. Mattos, J. G. Moreira, A. P. F. Atman
We introduce a new method based on cellular automata dynamics to study stochastic growth equations. The method defines an interface growth process which depends on height differenc…
Quasi-stationary distributions for the Domany-Kinzel stochastic cellular automaton
A. P. F. Atman, Ronald Dickman
We construct the {\it quasi-stationary} (QS) probability distribution for the Domany-Kinzel stochastic cellular automaton (DKCA), a discrete-time Markov process with an absorbing s…
Lattice Model for Approximate Self-Affine Soil Profiles
A. P. F. Atman, J. G. Vivas Miranda, A. Paz Gonzalez +1
A modeling of the soil structure and surface roughness by means of the concepts of the fractal growth is presented. Two parameters are used to control the model: the fragmentation…
