  • committed facility — an agreement by a bank to provide a customer with funds up to a specified limit at a specified rate of interest
  • common data format — (library)   (CDF) A library and toolkit based on a self-describing data format for scalar and multidimensional data. CDF aims to be platform- and discipline-independent. A scientific data management package (CDF Library) allows developers to manage data and metadata through APIs. CDF has built-in support for data compression (gZip, RLE, Huffman) and files larger than two gigabytes. There are interfaces for C, FORTRAN, Java, Perl, C#, Visual Basic, IDL and MATLAB.
  • compassion fatigue — the inability to react sympathetically to a crisis, disaster, etc, because of overexposure to previous crises, disasters, etc
  • composite function — a function obtained from two given functions, where the range of one function is contained in the domain of the second function, by assigning to an element in the domain of the first function that element in the range of the second function whose inverse image is the image of the element.
  • conditioned reflex — a reflex in which the response (e.g., secretion of saliva in a dog) is occasioned by a secondary stimulus (e.g., the ringing of a bell) repeatedly associated with the primary stimulus (e.g., the sight of meat)
  • configuration item — (jargon)   Hardware or software, or an aggregate of both, which is designated by the project configuration manager (or contracting agency) for configuration management.
  • constructive proof — (mathematics)   A proof that something exists that provides an example or a method for actually constructing it. For example, for any pair of finite real numbers n < 0 and p > 0, there exists a real number 0 < k < 1 such that f(k) = (1-k)*n + k*p = 0. A constructive proof would proceed by rearranging the above to derive an equation for k: k = 1/(1-n/p) From this and the constraints on n and p, we can show that 0 < k < 1. A few mathematicians actually reject *all* non-constructive arguments as invalid; this means, for instance, that the law of the excluded middle (either P or not-P must hold, whatever P is) has to go; this makes proof by contradiction invalid. See intuitionistic logic. Constructive proofs are popular in theoretical computer science, both because computer scientists are less given to abstraction than mathematicians and because intuitionistic logic turns out to be an appropriate theoretical treatment of the foundations of computer science.
  • continued fraction — a number plus a fraction whose denominator contains a number and a fraction whose denominator contains a number and a fraction, and so on
  • contract furniture — furniture designed and manufactured for commercial installation, as in offices, waiting rooms, or lobbies.
  • cooking facilities — equipment necessary for cooking
  • cost of goods sold — The cost of goods sold is the cost of purchasing goods for resale, added to the cost of the raw materials and labor used to manufacture goods that are sold in a particular period of time.
  • counterreformation — a reform movement to oppose a previous one
  • court of exchequer — (formerly) an English civil court where Crown revenue cases were tried
  • court of st. james — the British royal court
  • creeping featurism — (jargon)   /kree'ping fee'chr-izm/ (Or "feature creep") A systematic tendency to load more chrome and features onto systems at the expense of whatever elegance they may have possessed when originally designed. "The main problem with BSD Unix has always been creeping featurism." More generally, creeping featurism is the tendency for anything to become more complicated because people keep saying "Gee, it would be even better if it had this feature too". The result is usually a patchwork because it grew one ad-hoc step at a time, rather than being planned. Planning is a lot of work, but it's easy to add just one extra little feature to help someone, and then another, and another, .... When creeping featurism gets out of hand, it's like a cancer. Usually this term is used to describe computer programs, but it could also be said of the federal government, the IRS 1040 form, and new cars. A similar phenomenon sometimes afflicts conscious redesigns; see second-system effect. See also creeping elegance.
  • crested flycatcher — any of various tyrant flycatchers (esp. genus Myiarchus) with a prominent crest
  • crocodile-infested — full of crocodiles
  • crude oil fraction — A crude oil fraction is a component of crude oil, which has its own particular molecular composition, weight, and boiling point.
  • cultural diffusion — act of diffusing; state of being diffused.
  • current efficiency — the ratio of the actual mass of a substance liberated from an electrolyte by the passage of current to the theoretical mass liberated according to Faraday's law
  • curvature of field — a monochromatic aberration of a lens or other optical system in which the focal surface is curved, the refracted image of an object oriented perpendicular to the axis of the lens lying on a curved surface rather than in a plane perpendicular to the axis.
  • curvature of space — (in relativity) a property of space near massive bodies in which their gravitational field causes light to travel along curved paths.
  • cycle of indiction — indiction (def 3).
  • cycle-of-indiction — a proclamation made every 15 years in the later Roman Empire, fixing the valuation of property to be used as a basis for taxation.
  • data flow analysis — (programming)   A process to discover the dependencies between different data items manipulated by a program. The order of execution in a data driven language is determined solely by the data dependencies. For example, given the equations 1. X = A + B 2. B = 2 + 2 3. A = 3 + 4 a data-flow analysis would find that 2 and 3 must be evaluated before 1. Since there are no data dependencies between 2 and 3, they may be evaluated in any order, including in parallel. This technique is implemented in hardware in some pipelined processors with multiple functional units. It allows instructions to be executed as soon as their inputs are available, independent of the original program order.
  • data transfer rate — (communications)   (Or "throughput, data rate", "transmission rate") The amount of data transferred in one direction over a link divided by the time taken to transfer it, usually expressed in bits per second (bps), bytes per second (Bps) or baud. The link may be anything from an interface to a hard disk to a radio transmission from a satellite. Where data transfer is not continuous throughout the given time interval, the data transfer rate is thus an average rate that will be lower than the peak rate. The peak or maximum possible rate may itself be lower than the capacity of the communication channel if the channel is shared, or part of the signal is not considered as data, e.g. checksum or routing information. When applied to data rate, the multiplier prefixes "kilo-", "mega-", "giga-", etc. (and their abbreviations, "k", "M", "G", etc.) always denote powers of 1000. For example, 64 kbps is 64,000 bits per second. This contrasts with units of storage where they stand for powers of 1024, e.g. 1 KB = 1024 bytes. The other important characteristic of a channel is its latency. The bandwidth of a channel determines the data transfer rate but is a different characteristic, measured in Hertz. [Relationship?]

  • de-objectification — to present as an object, especially of sight, touch, or other physical sense; make objective; externalize.
  • dead-letter office — an office where undeliverable letters were taken for storage
  • declaration of war — a formal statement made by one country to another that a state of war now exists between them

  • definitive plumage — the plumage of a bird that, once attained, does not change significantly in color or pattern for the rest of the bird's life.
  • democratic deficit — any situation in which there is believed to be a lack of democratic accountability and control over the decision-making process
  • departure platform — a raised area at a railway station from which passengers can board trains prior to their departing
  • depth-first search — (algorithm)   A graph search algorithm which extends the current path as far as possible before backtracking to the last choice point and trying the next alternative path. Depth-first search may fail to find a solution if it enters a cycle in the graph. This can be avoided if we never extend a path to a node which it already contains. Opposite of breadth first search. See also iterative deepening.
  • dimethyl sulfoxide — DMSO.
  • disenfranchisement — to disfranchise.
  • disidentifications — Plural form of disidentification.
  • distress frequency — a radio frequency band reserved for emergency signals from aircraft or ships in distress.
