Reaction-diffusion computers

چکیده
The tutorial introduces a hot topic of novel and emerging computing paradigms and architectures --computation with travelling waves in reaction-diffusion non-linear media. A reaction-diffusion computer is a massively parallel computing device, where micro-volumes of the chemical medium act as elementary few-bit processors; and chemical species diffuse and react in parallel. In the reaction-diffusion computer both the data and the results of the computation are encoded as concentration profiles of the reagents, or local disturbances of concentrations, whilst the computation per se is performed via the spreading and interaction of waves caused by the local disturbances. The tutorial brings out results of decade-long studies in designing experimental and simulated prototypes of reaction-diffusion computing devices for image processing, path planning, robot navigation, computational geometry, logics and artificial intelligence.

متن کاملSynchronization and control of coupled reaction-diffusion systems of the FitzHugh-Nagumo type
We consider a FitzHugh-Nagumo Reaction-Diffusion type system (FHN). The dynamics of the reaction part induces a unique repulsive stationnary point (0, 0) and a unique attractive limit cycle. After a description of the asymptotic behaviour of the FHN system, we deal with the synchronization and control analysis of N coupled FHN systems.
متن کاملNumerical solutions for fractional reaction-diffusion equations
Fractional diffusion equations are useful for applications where a cloud of particles spreads faster than the classical equation predicts. In a fractional diffusion equation, the second derivative in the spatial variable is replaced by a fractional derivative of order less than two. The resulting solutions spread faster than the classical solutions and may exhibit asymmetry, depending on the fr...
متن کاملBifurcation analysis of nonlinear reaction-diffusion problems using wavelet-based reduction techniques
Using a computational method for numerical homogenization, we perform the coarse-scale bifurcation analysis of nonlinear reaction–diffusion problems in both uniform and spatially varying media. The method is based on wavelet decomposition and projection of the differential equation on coarse scale wavelet spaces. The approach is capable of capturing turning points and pitchfork bifurcations of ...
متن کاملA Filtering technique for System of Reaction Diffusion equations
We present here a fast parallel solver designed for a system of reaction convection diffusion equations. Typical applications are large scale computing of air quality models or numerical simulation of population models where several colonies compete. Reaction-Diffusion systems can be integrated in time by point-wise Newton iteration when all space dependent terms are explicit in the time integr...
