  • 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.
  • 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.
  • 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
  • displaced homemaker — a woman recently divorced, separated, or widowed after many years as a homemaker.
  • distillation column — a type of still fitted with interior baffles, used for fractional distillation. Compare still2 (def 1).
  • 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.
  • double-helical gear — herringbone gear.
  • draw the color line — to impose or accept the color line
  • dry-bulk cargo ship — a ship that carries an unpackaged dry cargo such as coal or grain; bulk carrier
  • 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
  • early purple orchid — a Eurasian orchid, Orchis mascula, with purplish-crimson flowers and stems marked with blackish-purple spots
  • eastern coral snake — any of numerous venomous elapid snakes, found chiefly in the New World tropics, as Micrurus fulvius (eastern coral snake) of the southeastern U.S., often brilliantly marked with bands of red, yellow, and black.
  • eat someone's lunch — to take into the mouth and swallow for nourishment; chew and swallow (food).
  • ecatepec de morelos — a city in S central Mexico, a suburb of Mexico City: on a 12th-century Aztec site.
  • echoencephalography — a device that employs reflected ultrasonic waves to examine the position of brain structures.
  • ecumenical movement — See under ecumenical (def 4).
  • 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.
  • elastomeric closure — An elastomeric closure is a component that closes a piece of packaging. An elastomeric closure is made from a material that is able to resume its original shape when it is removed from the packaging and may be in direct contact with the drug enclosed in the pack.
  • electro-shock baton — a baton used as a weapon to pass an electric current through part of the body
  • 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
  • electrodynamometers — Plural form of electrodynamometer.
  • electrohydrodynamic — (physics) Of or pertaining to electrohydrodynamics.
  • electromagnetically — By means of electromagnetism.
  • electromechanically — In an electromechanical way.
  • electron micrograph — a photograph or image of a specimen taken using an electron microscope
  • electronegativities — Plural form of electronegativity.
  • electronic graphics — (on television) the production of graphic designs and text by electronic means
  • electronic keyboard — a typewriter keyboard used to operate an electronic device such as a computer, word processor, etc
  • electronic magazine — (messaging, publication, web)   (e-zine) A regular publication on some particular topic distributed in digital form, chiefly now via the web but also by electronic mail or floppy disk. E-zines are often distributed for free by enthusiasts.
  • electropalatography — the study of the movements of the tongue during speech using touch-sensitive electrodes in the mouth linked to a computer
  • electrophoretically — By means of electrophoresis.
  • electrophotographic — Of or pertaining to electrophotography.
  • electrostatic field — an electric field associated with static electric charges
  • electrostatic units — the system of CGS electric and magnetic units that assigns the value of one to the dielectric constant of a vacuum
  • electrotherapeutics — (medicine) the use of electricity in therapeutics.
  • elevator controller — An archetypal dumb embedded-systems application, like toaster (which superseded it). During one period (1983--84) in the deliberations of ANSI X3J11 (the C standardisation committee) this was the canonical example of a really stupid, memory-limited computation environment. "You can't require "printf(3)" to be part of the default run-time library - what if you're targeting an elevator controller?" Elevator controllers became important rhetorical weapons on both sides of several holy wars.
  • emotional blackmail — a way of persuading someone to do something they do not want to do by making them feel guilty about it
  • enabling technology — technology that enables the user to perform a task or to improve his or her overall performance: e.g. the internet
  • entry qualification — the qualifications and conditions required to join an organization, club, etc
  • euclidean algorithm — Euclid's Algorithm
