Spatio-temporal Irregularity in an Excitable Medium with Shear Ow
نویسندگان
چکیده
We consider an excitable medium moving with relative shear, subjected to a localised disturbance which, in a stationary medium, would produce a pair of spiral waves. The spiral waves so created are distorted and then broken by the motion of the medium. Such breaks generate new spiral waves, and so a \chain reaction" of spiral wave births and deaths is observed. This leads to a complicated spatio-temporal pattern, the \frazzle gas" (term suggested in 5]), which eventually lls the whole medium. In this paper, we display and interpret the main features of the pattern.

متن کاملA neural model of hippocampal-parietal interactions in spatial memory
Excitable dynamics of a neuron generates dynamical phenomena with various attractors, which include deterministic chaos and multistability [1, 2]. A neural network composed of neurons with such excitable dynamics also produces much more interesting and richer nonlinear dynamics with spatio– temporal structure of spikes [3, 4]. In this talk, I consider nonlinear dynamics with spatio–temporal spi...
متن کاملSpatio-temporal patterns in two-dimensional excitable media subject to Robin boundary conditions
A numerical study of spiral wave propagation in two-dimensional excitable media subject to homogeneous Robin boundary conditions is presented, and it is shown that, depending on the magnitude of the transfer coefficient, periodic, almost periodic and nonperiodic dynamics may be observed. For transfer coefficients equal to or smaller than one, spiral waves almost identical to those obtained with...
متن کاملInfluence of Rigidity, Irregularity and Initial Stress on Shear Waves Propagation in Multilayered Media
The propagation of shear waves in an anisotropic fluid saturated porous layer over a prestressed semi-infinite homogeneous elastic half-space lying under an elastic homogeneous layer with irregularity present at the interface with rigid boundary has been studied. The rectangular irregularity has been taken in the half-space. The dispersion equation for shear waves is derived by using the pertur...
متن کاملZoning of Bamdej Wetland Water Quality based on the Spatio-temporal Kriging
Inland wetlands are of the most important natural terrestrial types of water resources. Against its importance in protecting and improving biodiversity, air quality and macro-climatic condition of their regions, industrial development, and urbanization treat their natural existence and behavior. Therefore, monitoring and quality evaluation of wetlands are necessary to analyze and infer their na...
