  • curly-coated retriever — a strongly built variety of retriever with a tightly curled black or liver-coloured coat
  • cycle of reincarnation — A term coined by Ivan Sutherland ca. 1970 to refer to a well-known effect whereby function in a computing system family is migrated out to special-purpose peripheral hardware for speed, then the peripheral evolves toward more computing power as it does its job, then somebody notices that it is inefficient to support two asymmetrical processors in the architecture and folds the function back into the main CPU, at which point the cycle begins again. Several iterations of this cycle have been observed in graphics-processor (blitter) design, and at least one or two in communications and floating-point processors. Also known as "the Wheel of Life", "the Wheel of Samsara" and other variations of the basic Hindu/Buddhist theological idea.
  • cylindrical coordinate — Usually, cylindrical coordinates. a member of a system of coordinates for locating a point in space by its polar coordinates and its perpendicular distance to the polar plane.
  • dalton's atomic theory — the theory that matter consists of indivisible particles called atoms and that atoms of a given element are all identical and can neither be created nor destroyed. Compounds are formed by combination of atoms in simple ratios to give compound atoms (molecules). The theory was the basis of modern chemistry

  • delaunay triangulation — (mathematics, graphics)   (After B. Delaunay) For a set S of points in the Euclidean plane, the unique triangulation DT(S) of S such that no point in S is inside the circumcircle of any triangle in DT(S). DT(S) is the dual of the voronoi diagram of S.
  • delayed-action shutter — a camera shutter that opens after an interval set by the photographer
  • deoxyribonucleoprotein — any of a class of nucleoproteins that yield DNA upon partial hydrolysis.
  • dicyclopentadienyliron — ferrocene (def 1).
  • diethylbarbituric acid — barbital
  • digital control system — (systems)   (DCS) A digital computer used for real-time control of a dynamic system, usually in an industrial environment, possibly as part of a Supervisory Control and Data Acquisition (SCADA) system. A DCS samples feedback from the system under control and modifies the control signals in an attempt to achieve some desired behaviour. Analysis of such digital-analogue feedback systems can involve mathematical methods such as difference equations, Laplace transforms, z transfer functions, state space models and state transition matrices.
  • directed acyclic graph — (DAG) A directed graph containing no cycles. This means that if there is a route from node A to node B then there is no way back.
  • directed-energy device — beam weapon.
  • directory system agent — (DSA) The software that provides the X.500 Directory Service for a portion of the directory information base. Generally, each DSA is responsible for the directory information for a single organisation or organisational unit.
  • disciplinary committee — a committee charged with examining alleged breaches of discipline within an organization, profession, etc and adjudicating on them
  • disposable soma theory — the theory that ageing is caused by the body having increasingly fewer resources to allocate towards repairing wear and damage to tissues
  • don't hold your breath — sth is unlikely to happen soon
  • drive-through delivery — childbirth after which the mother has a very brief hospital stay.
  • east african community — an association established in 1967 by Kenya, Uganda, and Tanzania to promote closer economic and social ties between member states: dissolved in 1977, but reformed in 1999, and joined in 2007 by Burundi and Rwanda
  • ectotrophic mycorrhiza — a type of mycorrhiza, typical of temperate and Boreal trees, in which the fungus forms a layer on the outside of the roots of the plant
  • electroencephalography — The measurement of electrical activity in different parts of the brain and the recording of such activity as a visual trace (on paper or on an oscilloscope screen).
  • electrolytic capacitor — An electrolytic capacitor is an electrical capacitor with an electrolyte between the two plates.
  • electrophysiologically — In an electrophysiological way.
  • employers' association — a body of employers, usually from the same sector of the economy, associated to further the interests of member companies by conducting negotiations with trade unions, providing advice, making representations to other bodies, etc
  • endotrophic mycorrhiza — the most widespread and common type of mycorrhiza, in which the fungus lives within the cells of the roots of the plant
  • entertainment industry — show business
  • every now and then etc — You use every in the expressions every now and then, every now and again, every once in a while, and every so often in order to indicate that something happens occasionally.
  • evolutionary algorithm — (EA) An algorithm which incorporates aspects of natural selection or survival of the fittest. An evolutionary algorithm maintains a population of structures (usually randomly generated initially), that evolves according to rules of selection, recombination, mutation and survival, referred to as genetic operators. A shared "environment" determines the fitness or performance of each individual in the population. The fittest individuals are more likely to be selected for reproduction (retention or duplication), while recombination and mutation modify those individuals, yielding potentially superior ones. EAs are one kind of evolutionary computation and differ from genetic algorithms. A GA generates each individual from some encoded form known as a "chromosome" and it is these which are combined or mutated to breed new individuals. EAs are useful for optimisation when other techniques such as gradient descent or direct, analytical discovery are not possible. Combinatoric and real-valued function optimisation in which the optimisation surface or fitness landscape is "rugged", possessing many locally optimal solutions, are well suited for evolutionary algorithms.
  • fall prey to something — To fall prey to something bad means to be taken over or affected by it.
  • federal reserve system — a U.S. federal banking system that is under the control of a central board of governors (Federal Reserve Board) with a central bank (Federal Reserve Bank) in each of 12 districts and that has wide powers in controlling credit and the flow of money as well as in performing other functions, as regulating and supervising its member banks.

  • frequency distribution — the correspondence of a set of frequencies with the set of categories, intervals, or values into which a population is classified.
  • frequency shift keying — (communications)   (FSK) The use of frequency modulation to transmit digital data, i.e. two different carrier frequencies are used to represent zero and one. FSK was originally used to transmit teleprinter messages by radio (RTTY) but can be used for most other types of radio and land-line digital telegraphy. More than two frequencies can be used to increase transmission rates.
  • frictional electricity — static electricity generated by friction
  • genitourinary medicine — the branch of medical science concerned with the study and treatment of diseases of the genital and urinary organs, esp sexually transmitted diseases
  • get a word in edgeways — to succeed in interrupting a conversation in which someone else is talking incessantly
  • go their separate ways — When two or more people who have been together for some time go their separate ways, they go to different places or end their relationship.
  • graph rewriting system — An extension of a term rewriting system which uses graph reduction on terms represented by directed graphs to avoid duplication of work by sharing expressions.
