  • dielectric constant — Electricity. the ratio of the flux density produced by an electric field in a given dielectric to the flux density produced by that field in a vacuum.
  • diethylaminoethanol — a colorless, hygroscopic, water-soluble liquid, C 6 H 15 NO, used for the synthesis of local anesthetics, in antirust compounds, and in photographic emulsions.
  • digital electronics — (electronics)   The implementation of two-valued logic using electronic logic gates such as and gates, or gates and flip-flops. In such circuits the logical values true and false are represented by two different voltages, e.g. 0V for false and +5V for true. Similarly, numbers are normally represented in binary using two different voltages to represented zero and one. Digital electronics contrasts with analogue electronics which represents continuously varying quantities like sound pressure using continuously varying voltages. Digital electronics is the foundation of modern computers and digital communications. Massively complex digital logic circuits with millions of gates can now be built onto a single integrated circuit such as a microprocessor and these circuits can perform millions of operations per second.
  • digital photography — the taking or manipulation of photographs that are stored as data files on a computer.
  • dimethylnitrosamine — a yellow, water-soluble carcinogenic liquid, C 2 H 6 N 2 O, found in tobacco smoke and certain foods: known to be a potent carcinogen. Abbreviation: DMN, DMNA.
  • diplomatic immunity — exemption from taxation, searches, arrest, etc., enjoyed by diplomatic officials and their dependent families under international law, and usually on a reciprocal basis.
  • direct grant school — (in Britain, formerly) a school financed by endowment, fees, and a state grant conditional upon admittance of a percentage of nonpaying pupils nominated by the local education authority
  • directional coupler — (communications)   (tap) A passive device used in cable systems to divide and combine radio frequency signals. A directional coupler has at least three ports: line in, line out, and the tap. The signal passes between line in and line out ports with loss referred to as the insertion loss. A small portion of the signal power applied to the line in port passes to the tap port. A signal applied to the tap port is passed to the line in port less the tap attenuation value. The tap signals are isolated from the line out port to prevent reflections. A signal applied to the line out port passes to the line in port and is isolated from the tap port. Some devices provide more than one tap output line (multi-taps).
  • disciplinary action — punishment or caution
  • dispersion relation — the relationship between the angular frequency (ω;) of a wave and the magnitude of its wave vector (k). Thus the wave's speed is ω/k
  • distillation column — a type of still fitted with interior baffles, used for fractional distillation. Compare still2 (def 1).
  • diversional therapy — the structured use of leisure time in recreation and play as a form of or supplement to conventional therapy
  • dobsonian telescope — a relatively inexpensive Newtonian telescope, suitable for visual but not photographic use, in which the tube assembly slips freely in the lower base.
  • dominant wavelength — the wavelength of monochromatic light that would give the same visual sensation if combined in a suitable proportion with an achromatic light
  • draw the color line — to impose or accept the color line
  • drink the health of — to salute or celebrate with a toast
  • dynamic translation — (architecture)   A virtual machine implementation approach, used to speed up execution of byte-code programs. To execute a program unit such as a method or a function, the virtual machine compiles its bytecodes into (hardware) machine code. The translated code is also placed in a cache, so that next time that unit's machine code can be executed immediately, without repeating the translation. This technique was pioneered by the commercial Smalltalk implementation currently known as VisualWorks, in the early 1980s. Currently it is also used by some implementations of the Java Virtual Machine under the name JIT (Just In Time compilation).
  • dynatron oscillator — type of oscillator
  • educational adviser — a person who provides advice and training to teachers about teaching methods and educational policies
  • eilean donan castle — a castle near the Kyle of Lochalsh in Highland, Scotland: built in the 13th century; famous for its picturesque setting
  • elastic deformation — In elastic deformation a material changes shape when a stress is applied to it but goes back to its original state when the stress is removed.
  • electrocardiographs — Plural form of electrocardiograph.
  • electrocardiography — The measurement of electrical activity in the heart and the recording of such activity as a visual trace (on paper or on an oscilloscope screen), using electrodes placed on the skin of the limbs and chest.
  • electrode potential — the potential difference developed when an electrode of an element is placed in a solution containing ions of that element
  • electrohydrodynamic — (physics) Of or pertaining to electrohydrodynamics.
  • electronic keyboard — a typewriter keyboard used to operate an electronic device such as a computer, word processor, etc
  • electrostatic field — an electric field associated with static electric charges
  • environmental audit — the systematic examination of an organization's interaction with the environment, to assess the success of its conservation or antipollution programme
  • euclidean algorithm — Euclid's Algorithm
  • first-sale doctrine — a legal principle allowing the purchaser of a lawfully made copy of a copyright-protected work to sell or give away that copy without permission but not to reproduce it.

  • fluoride toothpaste — toothpaste containing a small amount of fluoride as protection against tooth decay
  • functional database — (database, language)   A database which uses a functional language as its query language. Databases would seem to be an inappropriate application for functional languages since, a purely functional language would have to return a new copy of the entire database every time (part of) it was updated. To be practically scalable, the update mechanism must clearly be destructive rather than functional; however it is quite feasible for the query language to be purely functional so long as the database is considered as an argument. One approach to the update problem would use a monad to encapsulate database access and ensure it was single threaded. Alternative approaches have been suggested by Trinder, who suggests non-destructive updating with shared data structures, and Sutton who uses a variant of a Phil Wadler's linear type system. There are two main classes of functional database languages. The first is based upon Backus' FP language, of which FQL is probably the best known example. Adaplan is a more recent language which falls into this category. More recently, people have been working on languages which are syntactically very similar to modern functional programming languages, but which also provide all of the features of a database language, e.g. bulk data structures which can be incrementally updated, type systems which can be incrementally updated, and all data persisting in a database. Examples are PFL [Poulovassilis&Small, VLDB-91], and Machiavelli [Ohori et al, ACM SIGMOD Conference, 1998].
