The pattern represented by every finite patch of tiles in a Penrose tiling occurs infinitely many times throughout the tiling. They are quasicrystals: implemented as a physical structure a Penrose tiling will produce diffraction patterns with Bragg peaks and five-fold symmetry, revealing the repeated patterns and fixed orientations of its tiles ...
A mosaic is a pattern or image made of small regular or irregular pieces of colored stone, glass or ceramic, held in place by plaster/mortar, and covering a surface. [1] Mosaics are often used as floor and wall decoration, and were particularly popular in the Ancient Roman world.
For well-behaved tilings (e.g. substitution tilings with finitely many local patterns) holds: if a tiling is non-periodic and repetitive (i.e. each patch occurs in a uniformly dense way throughout the tiling), then it is aperiodic. [7]
A list of patterns that, when repeated to fill the cells of a Rule 30 automaton, repeat themselves after finitely many time steps. Frans Faase, 2003. Archived from the Original on 2013-08-08; Paving Mosaic Fractal. Basic introduction to the pattern of Rule 30 from the perspective of a LOGO software expert Olivier Schmidt-Chevalier.
Floor mosaics often have images of geometrical patterns, often interspersed with animals. Scenes of hunting and venatio , arena displays where animals are killed, are popular. Byzantine mosaics went on to influence artists in the Norman Kingdom of Sicily , in the Republic of Venice , and, carried by the spread of Orthodox Christianity , in ...
A wallpaper group (or plane symmetry group or plane crystallographic group) is a mathematical classification of a two-dimensional repetitive pattern, based on the symmetries in the pattern. Such patterns occur frequently in architecture and decorative art , especially in textiles , tiles , and wallpaper .
A digital pattern generator is a piece of electronic test equipment or software used to generate digital electronic stimuli. Digital electronics stimuli are a specific kind of electrical waveform varying between two conventional voltages that correspond to two logic states ("low state" and "high state", "0" and "1").
DK-Audio (also known as DK-Technologies) subsequently released the PT5300, which superseded the PT5230, accepting all of its pattern generator modules and included many new options and features developed by DK-Audio. It was the last physical pattern generator directly descending from the original PM5544 to generate the Philips circle pattern.
