This phenomenon, in which structured shapes appear as if from nowhere in dynamic systems is referred to as non-linear pattern formation (NPF) . At the heart of NPF is the fact that quite simple rules ...

In this paper, we demonstrate that many image processing and pattern formation effects of the simple Cellular Neural Network (CNN) can be understood by means of a common approach. By examining the ...

Phase diagram for filament formation. To gain insight into this filament formation, we compare in Fig. 2 the observed behaviour with that of a Newtonian fluid, Glycerine. The contact angle of the ...

Decades ago, Alan Turing showed how diffusion interacted with chemical reactions between two morphogens to produce stable patterns—something like the chemical waves shown here, in a so-called Belousov ...

In order to obtain more clear x-ray images, an antiscatter grid, which can absorb the scattered rays, is employed. In the high-resolution direct digital radiography, however, the artifacts due to the ...
