  • 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.
  • digital versatile disc — (storage)   (DVD, formerly "Digital Video Disc") An optical storage medium with improved capacity and bandwidth compared with the Compact Disc. DVD, like CD, was initally marketed for entertainment and later for computer users. [When was it first available?] A DVD can hold a full-length film with up to 133 minutes of high quality video, in MPEG-2 format, and audio. The first DVD drives for computers were read-only drives ("DVD-ROM"). These can store 4.7 GBytes - over seven times the storage capacity of CD-ROM. DVD-ROM drives read existing CD-ROMs and music CDs and are compatible with installed sound and video boards. Additionally, the DVD-ROM drive can read DVD films and modern computers can decode them in software in real-time. The DVD video standard was announced in November 1995. Matshusita did much of the early development but Philips made the first DVD player, which appeared in Japan in November 1996. In May 2004, Sony released the first dual-layer drive, which increased the disc capacity to 8.5 GB. Double-sided, dual-layer discs will eventually increase the capacity to 17 GB. Write-once DVD-R ("recordable") drives record a 3.9GB DVD-R disc that can be read on a DVD-ROM drive. Pioneer released the first DVD-R drive on 1997-09-29. By March 1997, Hitachi had released a rewritable DVD-RAM drive (by false analogy with random-access memory). DVD-RAM drives read and write to a 2.6 GB DVD-RAM disc, read and write-once to a 3.9GB DVD-R disc, and read a 4.7 GB or 8.5 GB DVD-ROM. Later, DVD-RAM discs could be read on DVD-R and DVD-ROM drives.
  • digital video recorder — See DVR.
  • dilation and curettage — a surgical method for the removal of diseased tissue or an early embryo from the lining of the uterus by means of scraping.
  • 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.
  • dishonorable discharge — the discharge of a person from military service for an offense more serious than one for which a bad-conduct discharge is given.
  • draft-quality printing — low-quality, high-speed output in printed form from a printer linked to a word processor

  • 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.
  • extension language kit — (language)   (Elk) A Scheme interpreter by Oliver Laumann <[email protected]> and Carsten Bormann <[email protected]> of the Technical University of Berlin. Elk was designed to be used as a general extension language. New types and primitive procedures can easily be added. It has first-class environments, dynamic-wind, fluid-let, macros, autoloading and a dump. It provides interfaces to Xlib, Xt and various widget sets; dynamic loading of extensions and object files; almost all artificial limitations removed; generational/incremental garbage collector; Unix system call extensions; Records (structures) and bit strings. Version: 2.2 is mostly R3RS compatible and runs on Unix, Ultrix, VAX, Sun-3, Sun-4, 68000, i386, MIPS, IBM PC RT, RS/6000, HP700, SGI, Sony, MS-DOS (gcc+DJGPP or go32).
