The QR code system was invented in 1994, at the Denso Wave automotive products company, in Japan. The initial alternating-square design presented by the team of researchers, headed by Masahiro Hara, was influenced by the black counters and the white counters played on a Go board; the pattern of position detection was found and determined by applying the least-used ratio (1:1:3:1:1) in black ...
A technetium-99m generator, or colloquially a technetium cow or moly cow, is a device used to extract the metastable isotope 99m Tc of technetium from a decaying sample of molybdenum-99. 99 Mo has a half-life of 66 hours [1] and can be easily transported over long distances to hospitals where its decay product technetium-99m (with a half-life ...
Code.org. Code.org is a non-profit organization and educational website founded by Hadi and Ali Partovi [1] aimed at K-12 students that specializes in computer science. [2] The website includes free coding lessons and other resources. The initiative also targets schools in an attempt to encourage them to include more computer science classes in ...

Polynomial code. In coding theory, a polynomial code is a type of linear code whose set of valid code words consists of those polynomials (usually of some fixed length) that are divisible by a given fixed polynomial (of shorter length, called the generator polynomial ).
Big Generator is the twelfth studio album by English progressive rock band Yes, released on 21 September 1987 by Atco Records.After touring in support of their previous album, 90125 (1983), which saw the band move from progressive rock towards a pop-oriented and commercially accessible direction, Yes started work on a follow-up in 1985 with producer Trevor Horn.
Documentation generator. A documentation generator is a programming tool that generates software documentation intended for programmers ( API documentation) or end users ( end-user guide), or both, from a set of source code files, and in some cases, binary files. Some generators, such as Javadoc, can use special comments to drive the generation.
Its generator polynomial as a cyclic code is given by. where is the set of quadratic residues of in the set and is a primitive th root of unity in some finite extension field of . The condition that is a quadratic residue of ensures that the coefficients of lie in . The dimension of the code is . Replacing by another primitive -th root of unity ...
