Acoustic Carpets      Open Access    Accepted paper online
MGV vol. 25, no. 1/4, 2016, pp. 3-12.
Initial-boundary value problem for linear acoustics has been solved in two spatial dimensions. It has been assumed that the initial acoustic field consists of two Gaussian distributions. Dirichlet boundary conditions with zero acoustic pressure at the boundaries have been imposed. The solution has been obtained with the help of a split-operator technique which resulted in a cellular automaton with uncountably many internal states. To visualize the results, the Python library matplotlib has been employed. It has been shown that attractive graphical output results in both the transient and stationary regimes. The visualization effects are similar to, but different from, the well-known quantum-mechanical carpets.
Key words: acoustics, Euler equations, split-operator method, visualization of physical fields.

Visualization of Nonlocality in Coupled Map Latices      Open Access    Accepted paper online
MGV vol. 25, no. 1/4, 2016, pp. 13-25.
Numerical simulations of coupled map lattices with various degree of nonlocality have been performed. Quantitative characteristics of recently introduced for local coupling have been applied in the nonlocal case. It has been attempted to draw qualitative conclusions about nonlocality from the emerging pictures.
Key words: coupled map lattices, nonlocality, density matrix, visualization.
