  • dimetric projection — a type of axonometric projection in which the object is shown with two of its three principal axes tilted equally from the plane of viewing
  • direct-vision prism — Amici prism.
  • discriminated union — (theory)   The discriminated union of two sets A and B is A + B = {(inA, a) | a in A} U {(inB, b)| b in B} where inA and inB are arbitrary tags which specify which summand an element originates from. A type (especially an algebraic data type) might be described as a discriminated union if it is a sum type whose objects consist of a tag to say which part of the union they belong to and a value of the corresponding type.
  • distribution system — The distribution system is the part of an electric system after the transmission system that is dedicated to delivering electric energy to an end user.
  • domain architecture — (systems analysis)   A generic, organisational structure or design for software systems in a domain. The domain architecture contains the designs that are intended to satisfy requirements specified in the domain model. A domain architecture can be adapted to create designs for software systems within a domain and also provides a framework for configuring assets within individual software systems.
  • 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).
  • 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.
  • electrohydrodynamic — (physics) Of or pertaining to electrohydrodynamics.
  • end of transmission — (character)   (EOT) The mnemonic for ASCII character 4.
  • endowment insurance — Endowment insurance is a type of life insurance that pays a particular sum directly to the policyholder at a stated date, or to a beneficiary if the policyholder dies before this date.
  • environmental audit — the systematic examination of an organization's interaction with the environment, to assess the success of its conservation or antipollution programme

  • extendible compiler — (language)   (ETC) A Fortran-like compiler that can be extended with macros.

Pathology. an abnormally enlarged vein mainly due to a persistent increase in venous pressure, occurring inside the anal sphincter of the rectum and beneath the mucous membrane (internal hemorrhoid) or outside the anal sphincter and beneath the surface of the anal skin (external hemorrhoid)
  • ipratropium bromide — an anticholinergic bronchodilator, C 20 H 30 BrNO 3 , used in the treatment of chronic bronchitis and in airway obstruction diseases.

  • manchester encoding — (communications, protocol)   A method of transmitting bits which enables the receiver to easily synchronise with the sender. A simple way of signalling bits might be to transmit a high voltage for some period for a 1-bit and a low voltage for a 0 bit: Bits Sent: 1 1 0 0 Signal: High ___ Low |___ Time: -> . . . . . However, when several identical bits are sent in succession, this provides no information to the receiver about when each bit starts and stops. Manchester encoding splits each bit period into two, and ensures that there is always a transition between the signal levels in the middle of each bit. This allows the receiver to synchronise with the sender. In normal Manchester encoding, a 1-bit is transmitted with a high voltage in the first period, and a low voltage in the second, and vice verse for the 0 bit: Bits Sent: 1 1 0 0 Signal: High Low || |_| || Time: -> . ' . ' . ' . ' . In Differential Manchester encoding, a 1-bit is indicated by making the first half of the signal equal to the last half of the previous bit's signal and a 0-bit is indicated by making the first half of the signal opposite to the last half of the previous bit's signal. That is, a zero bit is indicated by a transition at the beginning of the bit. Like normal Manchester encoding, there is always a transition in the middle of the transmission of the bit. Differential Manchester Encoding Bits Sent: 1 1 0 0 Signal: High __ Low |_| || || Time: -> . ' . ' . ' . ' . With each bit period half as long, twice as much bandwidth is required when using either of the Manchester encoding schemes.
