  • complete partial ordering — (theory)   (cpo) A partial ordering of a set under a relation, where all directed subsets have a least upper bound. A cpo is usually defined to include a least element, bottom (David Schmidt calls this a pointed cpo). A cpo which is algebraic and boundedly complete is a (Scott) domain.
  • computer-aided publishing — desktop publishing. Abbreviation: CAP.
  • conductiometric titration — a titration technique in which the end-point is determined by measuring the conductance of the solution
  • constant angular velocity — (storage)   (CAV) One of the two schemes for controlling the rate of rotation of the disk in a disk drive. Constant angular velocity keeps the rate of rotation constant. This means that the linear velocity of the disk under the head is larger when reading or writing the outer tracks. This in turn implies either a variation in the data rate to and from the heads or the bits per unit length along the track. The alternative, constant linear velocity, requires the rate of rotation of the disk to accelerate and decelerate according to the radial postion of the heads, increasing the energy use and vibration.
  • constant applicative form — (functional programming)   (CAF) A supercombinator which is not a lambda abstraction. This includes truly constant expressions such as 12, (+ 1 2), [1, 2, 3] as well as partially applied functions such as (+ 4). Note that this last example is equivalent under eta abstraction to \ x . + 4 x which is not a CAF. Since a CAF is a supercombinator, it contains no free variables. Moreover, since it is not a lambda abstraction it contains no variables at all. It may however contain identifiers which refer to other CAFs, e.g. c 3 where c = (* 2). A CAF can always be lifted to the top level of the program. It can either be compiled to a piece of graph which will be shared by all uses or to some shared code which will overwrite itself with some graph the first time it is evaluated. A CAF such as ints = from 1 where from n = n : from (n+1) can grow without bound but may only be accessible from within the code of one or more functions. In order for the garbage collector to be able to reclaim such structures, we associate with each function a list of the CAFs to which it refers. When garbage collecting a reference to the function we collect the CAFs on its list.
  • copenhagen interpretation — an interpretation of quantum mechanics developed by Niels Bohr and his colleagues at the University of Copenhagen, based on the concept of wave–particle duality and the idea that the observation influences the result of an experiment
  • court of general sessions — a local court with general jurisdiction, both civil and criminal.

  • dataphone digital service — (communications, product)   (DDS) The first private-line digital service offered by AT&T, with data rates typically at 2.4, 4.8, 9.6 and 56 kilobits per second. DDS is now part of AT&T's Accunet family of services. Most LEC (local exchange carriers) and IXC (IntereXchange Carriers) offer similar services.
  • decision support database — A database from which data is extracted and analysed statistically (but not modified) in order to inform business or other decisions. This is in contrast to an operational database which is being continuously updated. For example, a decision support database might provide data to determine the average salary of different types of workers, whereas an operational database containing the same data would be used to calculate pay check amounts. Often, decision support data is extracted from operation databases.

  • diesel-electric generator — A diesel-electric generator is a piece of equipment that uses diesel as a fuel to produce electricity.
  • digital rights management — (legal)   (DRM) Any technology used to limit the use of software, music, movies or other digital data. This generally relies on some interaction between the media and the system that plays it. For example, video DVDs usually include a region code. If this does not match the player's region code, the player will refuse to play the disc.
  • digital signal processing — (DSP) Computer manipulation of analog signals (commonly sound or image) which have been converted to digital form (sampled).
  • discrete cosine transform — (mathematics)   (DCT) A technique for expressing a waveform as a weighted sum of cosines. The DCT is central to many kinds of signal processing, especially video compression. Given data A(i), where i is an integer in the range 0 to N-1, the forward DCT (which would be used e.g. by an encoder) is: B(k) = sum A(i) cos((pi k/N) (2 i + 1)/2) i=0 to N-1 B(k) is defined for all values of the frequency-space variable k, but we only care about integer k in the range 0 to N-1. The inverse DCT (which would be used e.g. by a decoder) is: AA(i)= sum B(k) (2-delta(k-0)) cos((pi k/N)(2 i + 1)/2) k=0 to N-1 where delta(k) is the Kronecker delta. The main difference between this and a discrete Fourier transform (DFT) is that the DFT traditionally assumes that the data A(i) is periodically continued with a period of N, whereas the DCT assumes that the data is continued with its mirror image, then periodically continued with a period of 2N. Mathematically, this transform pair is exact, i.e. AA(i) == A(i), resulting in lossless coding; only when some of the coefficients are approximated does compression occur. There exist fast DCT algorithms in analogy to the Fast Fourier Transform.
