  • combinatorial analysis — the branch of mathematics concerned with the theory of enumeration, or combinations and permutations, in order to solve problems about the possibility of constructing arrangements of objects which satisfy specified conditions
  • combinatorial topology — the branch of topology that deals with the properties of geometric figures by considering the figures as being composed of elementary geometric figures, as points or lines.
  • comma separated values — (file format)   (CSV) A file format used as a portable representation of a database. Each line is one entry or record and the fields in a record are separated by commas. Commas may be followed by arbitrary space and/or tab characters which are ignored. If field includes a comma, the whole field must be surrounded with double quotes.
  • command line interface — (operating system)   A means of communication between a program and its user, based solely on textual input and output. Commands are input with the help of a keyboard or similar device and are interpreted and executed by the program. Results are output as text or graphics to the terminal. Command line interfaces usually provide greater flexibility than graphical user interfaces, at the cost of being harder for the novice to use. Consequently, some hackers look down on GUIs as designed For The Rest Of Them.

  • comparative musicology — ethnomusicology.
  • comparative psychology — the study of the similarities and differences in the behaviour of different species

  • compulsory liquidation — the liquidation of a business in order to settle its debts
  • computational geometry — (mathematics)   The study of algorithms for combinatorial, topological, and metric problems concerning sets of points, typically in Euclidean space. Representative areas of research include geometric search, convexity, proximity, intersection, and linear programming.
  • computational learning — grammatical inference
  • constitutional monarch — the sovereign in a constitutional monarchy
  • constructive dismissal — If an employee claims constructive dismissal, they begin a legal action against their employer in which they claim that they were forced to leave their job because of the behaviour of their employer.
  • contract of employment — a written agreement between an employer and an employee, that, taken together with the rights of each under statute and common law, determines the employment relations between them

  • cosmological principle — the theory that the universe is uniform, homogenous, and isotropic, and therefore appears the same from any position
  • criminal investigation — an investigation by the police into a crime
  • curriculum coordinator — a member of a teaching staff with a largely administrative function whose job is to ensure that a curriculum is effectively taught
  • d'alembert's principle — the principle that for a moving body the external forces are in equilibrium with the inertial forces; a generalization of Newton's third law of motion
  • 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
  • database normalisation — (database)   A series of steps followed to obtain a database design that allows for efficient access and storage of data in a relational database. These steps reduce data redundancy and the chances of data becoming inconsistent. A table in a relational database is said to be in normal form if it satisfies certain constraints. Codd's original work defined three such forms but there are now five generally accepted steps of normalisation. The output of the first step is called First Normal Form (1NF), the output of the second step is Second Normal Form (2NF), etc. First Normal Form eliminates repeating groups by putting each value of a multi-valued attribute into a new row. Second Normal Form eliminates functional dependencies on a partial key by putting the fields in a separate table from those that are dependent on the whole key. Third Normal Form eliminates functional dependencies on non-key fields by putting them in a separate table. At this stage, all non-key fields are dependent on the key, the whole key and nothing but the key. Fourth Normal Form separates independent multi-valued facts stored in one table into separate tables. Fifth Normal Form breaks out data redundancy that is not covered by any of the previous normal forms.
  • decompartmentalization — the act of decompartmentalizing
  • developmental disorder — any condition, such as autism or dyslexia, that appears in childhood and is characterized by delay in the development of one or more psychological functions, such as language skill
  • 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.
  • digital radio mondiale — (communications)   (DRM) A form of monaural digital broadcast using carrier frequencies below 30 MHz. DRM uses MPEG-4 AAC Main Profile and SBR at data rates of 16-25 kbps.
  • digital standard mumps — (DSM) DEC's version of MUMPS.
  • directional microphone — a microphone that has a greater sensitivity to sounds coming from a particular area in front of it: used to eliminate unwanted sounds.
  • 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
  • drumhead court-martial — a court-martial held, usually on a battlefield, for the summary trial of charges of offenses committed during military operations.
  • 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.
  • electromagnetic moment — a measure of the magnetic strength of a magnet or current-carrying coil, expressed as the torque produced when the magnet or coil is set with its axis perpendicular to unit magnetic flux density. It is measured in ampere metres squared
  • electronic mail client — mail user agent
  • electrothermal printer — a printer that produces characters by burning the image on specially coated paper
  • 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
  • end transmission block — (character)   (ETB) The mnemonic for ASCII character 23.
  • equal rights amendment — a proposed amendment to the US Constitution enshrining equality between the sexes
  • 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.
  • examining the entrails — The process of grovelling through a core dump or hex image in an attempt to discover the bug that brought a program or system down. The reference is to divination from the entrails of a sacrified animal. Compare runes, incantation, black art, desk check.
