Length of a module — In abstract algebra, the length of a module is a measure of the module s size . It is defined as the length of the longest ascending chain of submodules and is a generalization of the concept of dimension for vector spaces. The modules with… … Wikipedia
Extremal length — In the mathematical theory of conformal and quasiconformal mappings, the extremal length of a collection of curves Gamma is a conformal invariant of Gamma. More specifically, suppose thatD is an open set in the complex plane and Gamma is a… … Wikipedia
Variable-length code — In coding theory a variable length code is a code which maps source symbols to a variable number of bits. Variable length codes can allow sources to be compressed and decompressed with zero error (lossless data compression) and still be read back … Wikipedia
Arc length — Determining the length of an irregular arc segment is also called rectification of a curve. Historically, many methods were used for specific curves. The advent of infinitesimal calculus led to a general formula that provides closed form… … Wikipedia

Minimum description length — The minimum description length (MDL) principle is a formalization of Occam s Razor in which the best hypothesis for a given set of data is the one that leads to the best compression of the data. MDL was introduced by Jorma Rissanen in 1978. It is … Wikipedia
Run-length encoding — (RLE) is a very simple form of data compression in which runs of data (that is, sequences in which the same data value occurs in many consecutive data elements) are stored as a single data value and count, rather than as the original run. This is … Wikipedia
Run length limited — or RLL coding is a technique that is used to store data on recordable media. Specifically, RLL prevents long stretches of repeated bits from causing the signal recorded on media to not change for an excessive period, by modulating the data. RLL… … Wikipedia
