Central pattern generators (CPGs) are self-organizing biological neural circuits [1] [2] that produce rhythmic outputs in the absence of rhythmic input. [3] [4] [5] They are the source of the tightly-coupled patterns of neural activity that drive rhythmic and stereotyped motor behaviors like walking, swimming, breathing, or chewing.
Two principal techniques are used to produce seed beads: the wound method and the drawn method. The wound method is the more-traditional technique, is more time-consuming, and is no longer used in modern bead production: in this technique, a chunk of glass known in glassmaking as a gather and composed mainly of silica is heated on an iron bar until molten.
ATPG (acronym for both automatic test pattern generation and automatic test pattern generator) is an electronic design automation method or technology used to find an input (or test) sequence that, when applied to a digital circuit, enables automatic test equipment to distinguish between the correct circuit behavior and the faulty circuit behavior caused by defects.
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").
The most common type of modern glass bead is the seed bead, a small type of bead typically less than 6 mm (0.24 in), traditionally monochrome, and manufactured in very large quantities. They are a modern example of mechanically drawn glass beads.
The arrangement of pegs on the board constrains the possible patterns that can be produced on that board. Most fuse-beading is done on a square grid pegboard, but there are other arrangements like hexagonal grids. [4] Tweezers can be used to make bead placement easier. Square grids enable recreating pixel art.
