  • correlation coefficient — a statistic measuring the degree of correlation between two variables as by dividing their covariance by the square root of the product of their variances. The closer the correlation coefficient is to 1 or –1 the greater the correlation; if it is random, the coefficient is zero

  • dishonourable discharge — dismissal from the US armed forces by a court martial as a result of serious misconduct
  • disjunctive normal form — (DNF) A logical formula consisting of a disjunction of conjunctions where no conjunction contains a disjunction. E.g. the DNF of (A or B) and C is (A and C) or (B and C).
  • dissociate oneself from — to deny or repudiate any connection with
  • dollar (cost) averaging — see average (sense 11)
  • drop into someone's lap — to cause to be someone's responsibility

  • eastern lowland gorilla — the largest of the anthropoid apes, Gorilla gorilla, terrestrial and vegetarian, of western equatorial Africa and the Kivu highlands, comprising the subspecies G. g. gorilla (western lowland gorilla) G. g. graueri (eastern lowland gorilla) and G. g. beringei (mountain gorilla) now rare.
  • electroencephalographer — A specialist in electroencephalography.
  • electroencephalographic — Of or pertaining to electroencephalography or electroencephalographs.
  • electron spin resonance — a technique for investigating paramagnetic substances by subjecting them to high-frequency radiation in a strong magnetic field. Changes in the spin of unpaired electrons cause radiation to be absorbed at certain frequencies
  • electronic file cabinet — a device, controlled by software, for the storage and retrieval of information
  • electronic mail address — (messaging)   (Usually "e-mail address") The string used to specify the source or destination of an electronic mail message. E.g. "[email protected]". The RFC 822 standard is probably the most widely used on the Internet. X.400 was once used in Europe and Canada. UUCP-style (bang path) addresses or other kinds of source route became virtually extinct in the 1990s. In the example above, "john" is the local part which is the name of a mailbox on the destination computer. If the sender and recipient use the same computer, or the same LAN, for electronic mail then the local part is usually all that is required. If they use different computers, e.g. they work at different companies or use different Internet service providers, then the "host part", e.g. "sales.acme.com" must be appended after an "@". This usually takes the form of a fully qualified domain name or, within a large organisation, it may be just the hostname part, e.g. "sales". The destination computer named by the host part is usually a server of some kind rather than an individual's workstation or PC. The user's mail is stored on the server and read later via client mail software running on the user's computer. Large organisations, such as universities will often set up a global alias directory which maps a simple user name such as "jsmith" to an address which contains more information such as "[email protected]". This hides the detailed knowledge of where the message will be delivered from the sender, making it much easier to redirect mail if a user leaves or moves to a different department for example.
  • electronic surveillance — use of electronic devices to spy, observe
  • electrophotographically — In an electrophotographic manner; by means of electrophotography.
  • electrostatic discharge — (hardware, testing)   (ESD) One kind of test that hardware usually has to pass to prove it is suitable for sale and use. The hardware must still work after is has been subjected to some level of electrostatic discharge. Some organisations have their own ESD requirements which hardware must meet before it will be considered for purchase. Different countries have different legal regulations about levels of ESD. See also Radio Frequency Interference, Electromagnetic Compatibility.
  • electrostatic generator — any device for producing a high voltage by building up a charge of static electricity
  • electroweak interaction — a type of fundamental interaction combining both the electromagnetic interaction and the weak interaction
  • ellipsoid of revolution — a geometric surface produced by rotating an ellipse about one of its two axes and having circular plane surfaces perpendicular to the axis of revolution
  • encapsulated postscript — (EPS) An extension of the PostScript graphics file format developed by Adobe Systems. EPS is used for PostScript graphics files that are to be incorporated into other documents. An EPS file includes pragmas (special PostScript comments) giving information such as the bounding box, page number and fonts used. On some computers, EPS files include a low resolution version of the PostScript image. On the Macintosh this is in PICT format, while on the IBM PC it is in TIFF or Microsoft Windows metafile format.
  • entrance qualifications — academic requirements
  • equivalent focal length — the ratio of the size of an image of a small distant object near the optical axis to the angular distance of the object in radians
  • exclusive economic zone — the coastal water and sea bed around a country's shores, to which it claims exclusive rights for fishing, oil exploration, etc
  • execute channel program — (operating system)   (EXCP) An IBM system for low-level file access, where the programmer is completely responsible for providing a list of device-specific "channel comands" to be executed by I/O channels, control units and/or devices. The operating system will simply check the "CCW" chains for security purposes (access invalid memory or outside of file extents) and then schedule them for execution.
  • experimental psychology — the scientific study of the individual behaviour of man and other animals, esp of perception, learning, memory, motor skills, and thinking
  • expert judgement models — (programming)   A method of software estimation that is based on consultation with one or more experts that have experience with similar projects. An expert-consensus mechanism such as the Delphi Technique may be used to produce the estimate.
  • extracorporeal dialysis — the filtering of circulating blood through a semipermeable membrane in an apparatus
  • extremely low frequency — a radio frequency or radio-frequency band below 3 kilohertz
