  • customs declaration — a form declaring the nature and value of goods, etc, for customs purposes
  • customs regulations — the regulations relating to customs in a particular country
  • de broglie equation — the postulate of wave mechanics that a particle of mass m moving at a velocity v will have the properties of a wave of wavelength h / mv (de Broglie wavelength) where h is Planck's constant.
  • deindustrialisation — Alternative spelling of deindustrialization.
  • deindustrialization — the decline in importance of manufacturing industry in the economy of a nation or area
  • desargues's theorem — the theorem that if two triangles are so related that the lines joining corresponding vertices meet in a point, then the extended corresponding lines of the two triangles meet in three points, all on the same line.
  • difference equation — (mathematics)   A relation between consecutive elements of a sequence. The first difference is D u(n) = u(n+1) - u(n) where u(n) is the nth element of sequence u. The second difference is u(n+2) + a u(n+1) + b u(n) = 0 can be converted to a difference equation (in this case, a second order linear difference equation): D2 u(n) + p D u(n) + q u(n) = 0 and vice versa. a, b, p, q are constants.
  • differential backup — (operating system)   A kind of backup that copies all files that have changed since the last full backup. Each differential backup will include all files in previous differential backups since the full backup so to restore a version of a file, you only need to search the full backup and the relevant differential backup. Some systems support differential backup by associating an "Archive" flag with each file and setting this flag whenever the file is modified to indicate that it should be included in the next backup. A differential backup does not change this flag, whereas an incremental backup resets it.
  • 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).
  • discretionary trust — a trust in which the beneficiaries' shares are not fixed in the trust deed but are left to the discretion of other persons, often the trustees
  • 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.
  • distance university — a degree-granting institution operating wholly or mainly by correspondence courses for students not resident on or within commuting distance of the campus.
  • distinctive feature — a feature of the sound system of a language that serves as the crucial distinguishing mark between two phonemes, as the distinctive feature of voicing, which distinguishes b from p in English, or nasality, which distinguishes m from b and p.
  • 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.
