61Propulsive efficiency — In aircraft and rocket design, overall propulsive efficiency eta is the efficiency, in percent, with which the energy contained in a vehicle s propellant is converted into useful energy, to replace losses due to air drag, or gravity, or to… …
62Engine 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… …
63Faraday-efficiency effect — In electrochemistry, the Faraday efficiency effect is the potential misinterpretation of data through failure to take into account a Faraday efficiency of less than 100 per cent. Until recent decades it was common to assume that the release of… …
64Daylight saving time — This article is about daylight saving time in general. For DST in a specific location, see Daylight saving time by country. Summer time and DST redirect here. For other uses, see Summer time (disambiguation) and DST (disambiguation) …
65Dynamic efficiency — is a term in economics, which refers to an economy that appropriately balances short run concerns (static efficiency) with concerns in the long run (focusing on encouraging research and development).[1] Through dynamic efficiency, such an economy …
66Volumetric efficiency — in internal combustion engine design refers to the efficiency with which the engine can move the charge into and out of the cylinders. More correctly, volumetric efficiency is a ratio (or percentage) of what volume of fuel and air actually enters …
67Quantum efficiency — (QE) is a quantity defined for a photosensitive device such as photographic film or a charge coupled device (CCD) as the percentage of photons hitting the photoreactive surface that will produce an electron–hole pair [… …
68Cost efficiency — (or cost optimality), in the context of parallel computer algorithms, refers to a measure of how effectively parallel computing can be used to solve a particular problem. A parallel algorithm is considered cost efficient if its asymptotic running …
69overhead efficiency variance — overhead productivity variance; = productivity variance In a standard costing system, that part of the overhead total variance that arises from the more or less efficient use of the time available to carry out the actual production. It compares… …
