A three-layer cellular neural network is established to solve the reaction-diffusion model for real-time simulation of soft object deformation. A material flux based method is presented to derive internal forces from the potential energy distribution established by the reaction-diffusion model. The ...
The more interesting areas have been expanded and warped to fall within a rectangular shape, which can be useful as a user-interface for selecting pairs of k,f values to generate different reaction-diffusion patterns. For further information ...
To begin the iterative simulation the averaging area size should be chosen, and Boolean discretization of Ω′(0) should be done according to (9) to obtain Ω(0)={(u(0),m):u∈{0,1},m∈M}.Each tth Conclusion To make a conclusion about the proposed method of reaction–diffusion ...
The reaction naturally has two stable states: lots of A with no B to consume it, or lots of B where new A is quickly converted into more B. But the diffusion can cause interesting behaviors at the borders between the mostly-A and mostly-B areas. In this "mitosis" example, at convex ...
Snell’s law in reaction-diffusion systems 7 . Inward propagation of spiral waves in a reaction-diffusion system was recently observed in a water-in-oil AOT micro- emulsion 8 . In contrast to ordinary concentric or spiral waves, in which waves of chemical activity propagate out- ward from a...
To compare the computation time, we run the FEM simulation and CNN prediction to solve the reaction-diffusion equation with the same input configurations for 1,000 time steps. The comparison results of two FEM models and two CNN models are summarized in Table 1. We can observe that the ...

e k → Aj, where the rate constant k depends on the diffusion coefficient. Representing the diffusional motion as a chemical reaction allows to assimilate a reaction-diffusion system to a pure reaction system and to simulate it with Gillespie-inspired stochastic simulation algorithms. The stochastic...

We previously showed that the adult ocellated lizard skin colour pattern is effectively generated by a stochastic cellular automaton (CA) of skin scales. We additionally suggested that the canonical continuous 2D reaction-diffusion (RD) process of colour
