absolute efficiency
1Efficiency 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… …
2Absolute (fragrance) — Similar to essential oils, absolutes are concentrated, highly aromatic, oily mixtures extracted from plants. Whereas essential oils can typically be produced through steam distillation, absolutes require the use of solvent extraction techniques… …
3Algorithmic 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… …
4Thermal efficiency — In thermodynamics, the thermal efficiency (eta {th} ,) is a dimensionless performance measure of a thermal device such as an internal combustion engine, a boiler, or a furnace, for example. The input, Q {in} ,, to the device is heat, or the heat… …
5Kaldor-Hicks efficiency — (named for Nicholas Kaldor and John Hicks) is a measure of economic efficiency that captures some of the intuitive appeal of Pareto efficiency, but has less stringent criteria and is hence applicable to more circumstances. Under Kaldor Hicks… …
6Gamma spectroscopy — The gamma ray spectrum of natural uranium, showing about a dozen discrete lines superimposed on a smooth continuum, allows the identification the nuclides 226Ra, 214Pb, and 214Bi of the uranium decay chain. Gamma ray spectroscopy is the… …
7Thermoacoustic hot air engine — Thermoacoustic hot air engines (Sonic heat pump and refrigeration or thermoacoustic heat pump and refrigeration) of which nearly all are thermoacoustic stirling engines is a technology that uses high amplitude sound waves in a pressurized gas to… …
8Stove — A stove is an enclosed heated space. The term is commonly taken to mean an enclosed space in which fuel is burned to provide heating, either to heat the space in which the stove is situated or to heat the stove itself, and items placed on it, for …
9Expander cycle (rocket) — The expander cycle is a power cycle of a bipropellant rocket engine meant to improve the efficiency of fuel delivery.In an expander cycle, the fuel is heated before it is combusted, usually with waste heat from the main combustion chamber. As the …
