Memristive Excitable Cellular Automata
The memristor is a device whose resistance changes depending on the polarity and magnitude of a voltage applied to the device’s terminals. We design a minimalistic model of a regular network of memristors using structurally-dynamic cellular automata. Each cell gets info about states of its closest neighbours via incoming links. A link can be one ’conductive’ or ’non-conductive’ states. States o...

متن کاملAsymptotic Behavior of Excitable Cellular Automata
This research was partially supported by research grants to each of the authors from the National Science Foundation We study two families of excitable cellular automata known as the Greenberg–Hastings model and the cyclic cellular automaton. Each family consists of local deterministic oscillating lattice dynamics, with parallel discrete-time updating, parametrized by the range of interaction, ...
متن کاملRecurrent Ring Dynamics in Two–dimensional Excitable Cellular Automata
The Greenberg–Hastings model (GHM) is a simple cellular automaton which emulates two properties of excitable media: excitation by contact and a refractory period. We study two ways in which external stimulation can make ring dynamics in the GHM recurrent. The first scheme involves initial placement of excitation centers which gradually lose strength, i.e. each time they become inactive (and the...
متن کاملComputational Aspects of Modeling Excitable Media Using Cellular Automata
The study of excitable media is important in understanding the behavior of complex systems including mold growth, star formation, and cardiac tissue contraction. In this paper we discuss some computational aspects of modeling excitable media using multi-state cellular automata. In particular, we discuss implementation issues, algorithm development and visualization on the AGILA High Performance...
