complementarity principle — the principle that experiments on physical systems of atomic size or smaller, as electrons or photons, can exhibit either particle or wave behavior but not both simultaneously.
complete inference system — (logic) An inference system A is complete with respect to another system B if A can reach every conclusion which is true in B. The dual to completeness is soundness.
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.

conductiometric titration — a titration technique in which the end-point is determined by measuring the conductance of the solution
configuration programming — (programming) An approach that advocates the use of a separate configuration language to specify the coarse-grain structure of programs. Configuration programming is particularly attractive for concurrent, parallel and distributed systems that have inherently complex program structures.
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.
constructional homonymity — the property of a string of morphemes that is susceptible of two or more syntactic analyses, as in Flying planes can be dangerous, planes may be either the object of flying or the subject of can.

develop-mentally disabled — a disability, as mental retardation or cerebral palsy, that begins at an early age and continues indefinitely, leading to substantial handicap.
device independent bitmap — (graphics, file format) (DIB) An image format in which the sequence and depth of pixels in the file is not specifically related to their layout in any particular device. This allows any device dependent bitmap (DDB) image to be converted to or DIB format without loss of information, and this can then later be converted to other DDB formats for, e.g., printing or display. Rather than requiring converters from each DDB format to all other formats, only converters to and from DIB are needed. DIB images are normally transferred in metafiles, bmp files, and the clipboard. Transferring colour bitmaps from one device to another was not possible in versions of Microsoft Windows earlier than 3.0. Application programs can build DIB images without any interaction with Windows. If Windows lacks a drawing primitive, the application can simulate it directly into the DIB instead of using the existing graphics device interface (GDI) primitives. Unfortunately, under Windows versions 3.0 and 3.1, GDI cannot perform output operations directly to a DIB. Conversion between DIB and DDB is performed by the device driver. Where the driver does not have this facility, the conversion is performed by GDI but only in monochrome. DIBs are slower to use than device dependent bitmaps due to the conversions required.
dibasic calcium phosphate — Dibasic calcium phosphate is a white powder or crystalline substance used as a dietary supplement and tableting agent.
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.
diminished responsibility — law: lack of capacity
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.
document image processing — (DIP) Storage, management and retrieval of images.
domain architecture model — (systems analysis) A set of software architectures generic to a domain that define organising frameworks for constructing new application designs and implementations within the domain, consistent with the domain requirements model.

dual tone multi frequency — (communications) (DTMF, or "touch-tone") A method used by the telephone system to communicate the keys pressed when dialling. Pressing a key on the phone's keypad generates two simultaneous tones, one for the row and one for the column. These are decoded by the exchange to determine which key was pressed.
electric submersible pump — An electric submersible pump is a downhole pump which is powered by electricity, and used for lifting fluids.
electromagnetic radiation — radiation consisting of self-sustaining oscillating electric and magnetic fields at right angles to each other and to the direction of propagation. It does not require a supporting medium and travels through empty space at the speed of light

embedded lisp interpreter — (language) (ELI) A small Common Lisp-like interpreter embedded in the Andrew mail system, written by Bob Glickstein at CMU.
entity-relationship model — (database, specification) An approach to data modelling proposed by P. Chen in 1976. The model says that you divide your database in two logical parts, entities (e.g. "customer", "product") and relations ("buys", "pays for"). One of the first activities in specifying an application is defining the entities involved and their relationships, e.g. using an entity-relationship diagram to represent a model.
equine infectious anaemia — a viral disease of horses, donkeys, and mules characterized by fever, anaemia, jaundice, depression, and weight loss
examination for discovery — a pretrial meeting to disclose evidence that will be presented later
extended backus-naur form — (language) Any variation on the basic Backus-Naur Form (BNF) meta-syntax notation with (some of) the following additional constructs: square brackets "[..]" surrounding optional items, suffix "*" for Kleene closure (a sequence of zero or more of an item), suffix "+" for one or more of an item, curly brackets enclosing a list of alternatives, and super/subscripts indicating between n and m occurrences. All these constructs can be expressed in plain BNF using extra productions and have been added for readability and succinctness.
fallacy of many questions — the rhetorical trick of asking a question that cannot be answered without admitting a presupposition that may be false, as have you stopped beating your wife?
