  • concurrent massey hope — (language, functional programming)   An extension of Massey Hope, by Peter Burgess, Robert Pointon, and Nigel Perry <[email protected]> of Massey University, NZ, that provides multithreading and typed inter-thread communication. It uses C for intermediate code rather than assembly language.
  • conservation of energy — the principle that the total energy of any isolated system is constant and independent of any changes occurring within the system
  • conservation of parity — the principle that the parity of the total wave function describing a system of elementary particles is conserved. In fact it is not conserved in weak interactions

  • coronary insufficiency — inadequate circulation of blood through the coronary arteries, characterized by attacks of angina pectoris
  • countryside commission — (formerly, in Britain) a body which co-ordinated government activity in England and Wales in relation to the countryside
  • curly-coated retriever — a strongly built variety of retriever with a tightly curled black or liver-coloured coat
  • 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.
  • cyclic redundancy code — cyclic redundancy check
  • 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.
  • 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
  • days of wine and roses — a period of happiness and prosperity.
  • debt collection agency — a company that collects debts on behalf of creditors
  • dehydroepiandrosterone — the most abundant steroid in the human body, that is involved in the manufacture of testosterone, oestrogen, progesterone, and corticosterone
  • 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).
  • 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.
  • dihydroxyphenylalanine — dopa.
  • 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.
  • earn one's daily bread — to earn one's living
  • 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
  • ecclesiastical society — (in Congregational churches) a legal corporation with power to sue and be sued and to administer all of the temporalities of the church.
  • economy-class syndrome — Economy-class syndrome is a serious medical condition caused by blood clots in the legs moving up to the lungs; used especially in connection with long-haul flights.
  • 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
  • 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).
  • electrolytic capacitor — An electrolytic capacitor is an electrical capacitor with an electrolyte between the two plates.
  • electrophysiologically — In an electrophysiological way.
  • emergency road service — a form of motoring insurance that sends assistance to drivers when their vehicles break down on a journey; it is provided either by the national or regional automobile association or by a private insurance company
  • 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
  • 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.
  • explosive cyclogenesis — a rapid drop in pressure at the centre of a storm system, causing it to become greatly intensified
  • fall prey to something — To fall prey to something bad means to be taken over or affected by it.
