  • cut a long story short — to leave out details in a narration
  • 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.

  • cytidine monophosphate — a nucleotide constituent of ribonucleic acids; a phosphoric acid ester of cytidine. Abbreviation: CMP.
  • 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
  • debt collection agency — a company that collects debts on behalf of creditors

  • 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
  • denying the antecedent — the fallacy of inferring the falsehood of the consequent of a conditional statement, given the truth of the conditional and the falsehood of its antecedent, as if there are five of them, there are more than four: there are not five, so there are not more than four
  • deoxyribonucleoprotein — any of a class of nucleoproteins that yield DNA upon partial hydrolysis.
  • design system language — J. Gaffney, Evans & Sutherland 1976. Interpretive FORTH-like language for 3d graphics databases. Earliest forerunner of both Interpress and PostScript. Mentioned in PostScript Language Reference Manual, Adobe Systems, A-W 1985.
  • dicyclopentadienyliron — ferrocene (def 1).
  • 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-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
  • don't hold your breath — sth is unlikely to happen soon
  • draft-quality printing — low-quality, high-speed output in printed form from a printer linked to a word processor
  • 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
  • educational psychology — a branch of psychology concerned with developing effective educational techniques and dealing with psychological problems in schools.
  • educational technology — the use of technology, such as computers, within education, to aid the learning process
  • 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).
  • 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.
  • fallacy of composition — the fallacy of inferring that a property of parts or members of a whole is also a property of the whole (opposed to fallacy of division).
  • fetal alcohol syndrome — a pattern of birth defects caused by maternal consumption of alcohol during pregnancy: considered as one of the fetal alcohol spectrum disorders. Abbreviation: FAS.
  • 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
  • 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.
  • graphical display unit — an output device incorporating a cathode ray tube on which both line drawings and text can be displayed. It is usually used in conjunction with a light pen to input or reposition data
  • greystone technologies — (company)   The producers of the GT/M MUMPS compiler and GT/SQL pre-processor for VAX and DEC Alpha.
