  • diamond-leaf laurel — a tree, Pittosporum rhombifolium, of Australia, having coarsely toothed, oval or diamond-shaped leaves and white flowers, widely planted as an ornamental in the southwestern U.S.
  • 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).
  • disadvantageousness — The state or quality of being disadvantageous.
  • disambiguation page — a page on a website that lists various websites or web pages that have or could have the same title. The user is able to select from the list that page, site etc that he or she actually wants
  • 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.
  • distinguishableness — The state or quality of being distinguishable.
  • 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.
  • draw the curtain on — to end
  • duplicating machine — a duplicator, especially one for making identical copies of documents, letters, etc.

  • euclidean algorithm — Euclid's Algorithm
  • fault-based testing — (testing)   Software testing using test data designed to demonstrate the absence of a set of pre-specified faults; typically, frequently occurring faults. For example, to demonstrate that the software handles or avoids divide by zero correctly, the test data would include zero.
  • foundation subjects — the subjects studied as part of the National Curriculum, including the compulsory core subjects
  • free alongside quay — (of a shipment of goods) delivered to the quay without charge to the buyer
  • 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].
  • functional medicine — individualized medical care that recognizes the interactions between genetic and environmental factors and between the body's interconnected systems.
  • future date testing — (testing)   The process of setting a computer's date to a future date to test a program's (expected or unexpected) date sensitivity. Future date testing only shows the effects of dates on the computer(s) under scrutiny, it does not take into account knock-on effects of dates on other connected systems.
