Extended mean-field study of a stochastic cellular automaton
Physical Review E, 1994Extended mean-field theory is used for studying the one-dimensional stochastic cellular automaton with Rule 18 defined by Wolfram [Rev. Mod. Phys. 55, 601 (1983)]. The analysis is carried out at different levels taking n-point and n-pair correlations explicitly into consideration. The pair approximations reproduce the exact results in the deterministic

, 2016 A stochastic cellular automaton model of non-linear diffusion and diffusion with reaction
Journal of Computational Physics, 1991Abstract This article presents a stochastic cellular automaton model of diffusion and diffusion with reaction. The master equations for the model are examined, and we assess the difference between the implementation in which a single particle at a time moves (asynchronous dynamics) and one implementation in which all particles move simultaneously ...

Modeling of competition between three spatially distributed actors using a cellular automaton
Horizons of mathematical modeling and theory of self-organization. On the occasion of the 95th anniversary of the birth of S.P. KurdyumovaThis paper considers competition between three spatially distributed actors, such as conditional informations, when their relative strengths form a cycle.

On a Simple Stochastic Cellular Automaton with Avalanches: Simulation and Analytical Results
2010Cellular automata (CA) models are widely used in many natural and human sciences. The rule that defines CA, which may be very simple, can lead to a very complicated evolution of a system and rich structure of produced patterns. It often comes from nonlinearity present in the system.

Ghost Stochastic Resonance From an Asynchronous Cellular Automaton Neuron Model
IEEE Transactions on Circuits and Systems II: Express Briefs, 2013A novel electronic circuit neuron model whose nonlinear dynamics is described by an asynchronous cellular automaton is proposed. The model exhibits a so-called ghost stochastic resonance , which is suggested to be utilized in a nonlinear pitch extraction function in a biological auditory system.

The aim was to investigate how does a city configuration influence on a lethal disease spread. For this purpose, several configurations for subareas with high and low population density are considered.

Object Oriented Cellular Automaton for Multiple Lane Road Traffic Noise Mapping
2024 International Conference on Applied Mathematics & Computer Science (ICAMCS)Due to the traffic and its noise emission, road infrastructures represent a major source of illness. Noise measurement campaigns in order to produce map noises are essential for the decision-making of urban and suburban areas, yet wide measurements turn ...

AbstractWe investigate the speed of invasion waves for a single species generated by stochastic short‐ and/or long‐distance colonizations in a time‐continuous cellular automaton (CA) model on a two‐dimensional homogenous landscape. By simulating the CA models, we demonstrate that stochasticity can dramatically increase the speed of invasion compared to

The Operator Splitting scheme is a favourite and approved method for simulating multi component reactive transport systems. This scheme can easily be applied to the situation where large time scale differences between the transport and reaction steps exist.
