Compression stockings — and socks are specialised hosiery items designed to increase blood circulation. Their main theraputic purpose is to provide graduated pressure on the lower leg and foot and, in some cases, the thigh, to alleviate circulatory problems such as… … 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
Compression driver — A compression driver is a type of loudspeaker driver which uses the technique of compression to achieve high efficiencies. In this context compression refers to the fact that the area of the loudspeaker diaphragm is significantly larger than the… … Wikipedia
compression ratio — Auto. the ratio of the cylinder volume enclosed by the piston at its outermost position to the volume enclosed by it at its innermost position. [1905 10] * * * Degree to which the fuel mixture in an internal combustion engine is compressed before … Universalium
Efficiency wages — In labor economics, the efficiency wage hypothesis argues that wages, at least in some markets, are determined by more than simply supply and demand. Specifically, it points to the incentive for managers to pay their employees more than the… … Wikipedia
compression — [1] Applying pressure to a spring, or any springy substance, thus causing it to reduce its length in the direction of the compressing force. [2] Applying pressure to a gas, thus causing a reduction in volume. [3] One of the essential factors in a … Dictionary of automotive terms
compression leakage — In an engine, when some gases escape past the piston because the rings or cylinder walls are worn, the compression is reduced so that there is less efficiency … Dictionary of automotive terms
Fractal compression — is a lossy image compression method using fractals to achieve high levels of compression. The method is best suited for photographs of natural scenes (trees, mountains, ferns, clouds). The fractal compression technique relies on the fact that in… … Wikipedia

Algorithmic efficiency — In computer science, efficiency is used to describe properties of an algorithm relating to how much of various types of resources it consumes. Algorithmic efficiency can be thought of as analogous to engineering productivity for a repeating or… … Wikipedia
Engine efficiency — of thermal engines is the relationship between the total energy contained in the fuel, and the amount of energy used to perform useful work. There are two classifications of thermal engines (1) Internal combustion (gasoline, diesel and gas… … Wikipedia
