https://en.wikipedia.org/wiki/Fractal%20compression | Fractal compression is a lossy compression method for digital images, based on fractals. The method is best suited for textures and natural images, relying on the fact that parts of an image often resemble other parts of the same image. Fractal algorithms convert these parts into mathematical data called "fractal codes... |
https://en.wikipedia.org/wiki/Unknot | In the mathematical theory of knots, the unknot, not knot, or trivial knot, is the least knotted of all knots. Intuitively, the unknot is a closed loop of rope without a knot tied into it, unknotted. To a knot theorist, an unknot is any embedded topological circle in the 3-sphere that is ambient isotopic (that is, de... |
https://en.wikipedia.org/wiki/Vaporware | In the computer industry, vaporware (or vapourware) is a product, typically computer hardware or software, that is announced to the general public but is late, never actually manufactured, or officially cancelled. Use of the word has broadened to include products such as automobiles.

https://en.wikipedia.org/wiki/Topological%20ring | In mathematics, a topological ring is a ring that is also a topological space such that both the addition and the multiplication are continuous as maps:
where carries the product topology. That means is an additive topological group and a multiplicative topological semigroup.
Topological rings are fundamentally re... |
https://en.wikipedia.org/wiki/Dot%20matrix | A dot matrix is a 2-dimensional patterned array, used to represent characters, symbols and images. Most types of modern technology use dot matrices for display of information, including mobile phones, televisions, and printers. The system is also used in textiles with sewing, knitting and weaving.
An alternate form of... |
https://en.wikipedia.org/wiki/Rasterisation | In computer graphics, rasterisation (British English) or rasterization (American English) is the task of taking an image described in a vector graphics format (shapes) and converting it into a raster image (a series of pixels, dots or lines, which, when displayed together, create the image which was represented via sha... |

The U.S. Navy under Admirals Chester W. Nimitz, Frank J. Fletcher, and Raymond A. Spruance de... |
https://en.wikipedia.org/wiki/I-adic%20topology | In commutative algebra, the mathematical study of commutative rings, adic topologies are a family of topologies on the underlying set of a module, generalizing the -adic topologies on the integers.
Definition
Let be a commutative ring and an -module. Then each ideal of determines a topology on called the -adic to... |
https://en.wikipedia.org/wiki/Wireless%20community%20network | Wireless community networks or wireless community projects or simply community networks, are non-centralized, self-managed and collaborative networks organized in a grassroots fashion by communities, non-governmental organizations and cooperatives in order to provide a viable alternative to municipal wireless networks ... |
