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").
Picogen - a cross platform open source terrain generator; Sterling – freeware software for Windows; Terragen – a fractal terrain generator that can render animations for Windows and Mac OS X; Ultra Fractal – proprietary fractal generator for Windows and Mac OS X; Wolfram Mathematica – can be used specifically to create fractal images
Valentina is an open source pattern drafting software tool, designed to be the foundation of a new stack of open source tools to remake the garment industry. [5] The program was named after mother of the founder Roman Telezhinsky, a cutter by profession, who gave him the idea for the project.
A Siemens star, or spoke target, is a device used to test the resolution of optical instruments, printers, and displays. It consists of a pattern of bright "spokes" on a dark background that radiate from a common center and become wider as they get further from it.
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.
DeepDream is a computer vision program created by Google engineer Alexander Mordvintsev that uses a convolutional neural network to find and enhance patterns in images via algorithmic pareidolia, thus creating a dream-like appearance reminiscent of a psychedelic experience in the deliberately overprocessed images.

The stator windings of a practical delta-connected three-phase generator, shown in the following figure, can be converted to an equivalent wye-connected generator, using the six following formulas [a]: Practical generator connected in delta/triangle/pi. The quantities shown are phasor voltages and complex impedances. Click on image to expand it.
Eta Persei (η Persei, abbreviated Eta Per, η Per), is a binary star and the 'A' component of a triple star system (the 'B' component is the star HD 237009) [8] in the constellation of Perseus. Parallax measurements by the Gaia spacecraft imply that it is 1,000 is light-years away from Earth . [ 1 ]
