Differential cryptanalysis — is a general form of cryptanalysis applicable primarily to block ciphers, but also to stream ciphers and cryptographic hash functions. In the broadest sense, it is the study of how differences in an input can affect the resultant difference at… … Wikipedia
Differential TTL — is a type of binary electrical signaling based on the TTL (transistor transistor logic) standard. Normal TTL signals are single ended, which means that each signal consists of a voltage on one wire, referenced to a system ground. The low voltage… … Wikipedia
differential windlass — n. a windlass with two drums of different diameters providing a mechanical advantage … English World dictionary
Differential geometry of surfaces — Carl Friedrich Gauss in 1828 In mathematics, the differential geometry of surfaces deals with smooth surfaces with various additional structures, most often, a Riemannian metric. Surfaces have been extensively studied from various perspectives:… … Wikipedia
Differential signaling — This article is about electric signals via wires. For an immunological model attempting to explain how T cells survive selection during maturation, see Differential Signaling Hypothesis. Differential signaling is a method of transmitting… … Wikipedia
Differential pulley — Figure 1 Differential pulley. A differential pulley, sometimes called a chain hoist, or sometimes colloquially called a chain fall, is used to manually lift very heavy objects like car engines. It is operated by pulling upon the slack… … Wikipedia

Differential (infinitesimal) — For other uses of differential in calculus, see differential (calculus), and for more general meanings, see differential. In calculus, a differential is traditionally an infinitesimally small change in a variable. For example, if x is a variable … Wikipedia
differential interference contrast — Method of image formation in the light microscope based on the method proposed by Nomarski (though strictly speaking all forms of optical microscopy rely to a greater or lesser extent on differential interference). The light beam is split by a… … Dictionary of molecular biology
differential windlass — a pair of hoisting drums of different diameter turning at the same rate, such that a pulley suspended below them on a line wound on the larger drum and unwound from the smaller drum is raised with mechanical advantage. Also called Chinese… … Universalium
