Mean effective pressure — The mean effective pressure is a quantity related to the operation of an reciprocating engine and is a valuable measure of an engine s capacity to do work that is independent of engine displacement[1]. When quoted as an indicated mean effective… … Wikipedia
Odds ratio — The odds ratio [1][2][3] is a measure of effect size, describing the strength of association or non independence between two binary data values. It is used as a descriptive statistic, and plays an important role in logistic regression. Unlike… … Wikipedia
Compression ratio — For compression ratio in data compression, see data compression ratio. The compression ratio of an internal combustion engine or external combustion engine is a value that represents the ratio of the volume of its combustion chamber from its… … Wikipedia
Noise reduction — For sound proofing, see soundproofing. For scientific aspects of noise reduction of machinery and products, see noise control. Noise reduction is the process of removing noise from a signal. All recording devices, both analogue or digital, have… … Wikipedia
Data compression ratio — Data compression ratio, also known as compression power, is a computer science term used to quantify the reduction in data representation size produced by a data compression algorithm. The data compression ratio is analogous to the physical… … Wikipedia
Signal-to-noise ratio — For signal to noise ratio in statistics, see Cohen s d. Signal to noise ratio (often abbreviated SNR or S/N) is a measure used in science and engineering that compares the level of a desired signal to the level of background noise. It is defined… … Wikipedia
