A modified cellular automaton using activation and inhibition regions geometrically compatible with biaxial anisotropy
R. Piasecki, W. Olchawa, D. Fraczek
Young's cellular automaton, recently applied to study the spatiotemporal evolution of binary patterns for favorable/hostile environments, has now been modified from a different poi…
Anisotropic ferromagnet with two spins per site
R. Piasecki
Green function diagrammatic technique is used to investigate a model ferromagnet in the case, when the effective spin at a site is compounded of two anisotropically interacting ele…
A Two-Stage Reconstruction of Microstructures with Arbitrarily Shaped Inclusions
R. Piasecki, W. Olchawa, D. Frączek +1
The main goal of our research is to develop an effective method with a wide range of applications for the statistical reconstruction of heterogeneous microstructures with compact i…
Sensitivity to initial conditions in an extended activator-inhibitor model for the formation of patterns
R. Piasecki, W. Olchawa, K. Smaga
Despite simplicity, the synchronous cellular automaton [D.A. Young, Math. Biosci. 72, 51 (1984)] enables reconstructing basic features of patterns of skin. Our extended model allow…
Statistical Reconstruction of Microstructures Using Entropic Descriptors
R. Piasecki, W. Olchawa, D. Frączek +1
We report a multiscale approach of broad applicability to stochastic reconstruction of multiphase materials, including porous ones. The approach devised uses an optimization method…
Controlling spatial inhomogeneity in prototypical multiphase microstructures
D. Frączek, R. Piasecki, W. Olchawa +1
A wide variety of real random composites can be studied by means of prototypes of multiphase microstructures with a controllable spatial inhomogeneity. To create them, we propose a…
