  • legal dictionary — a specialized dictionary covering terms used in the various branches of the legal profession, as civil law, criminal law, and corporate law. A comprehensive legal dictionary adds to its body of standard English entries many words and phrases that have made their way into modern legal practice from law French and Latin and are rarely found in a general English monolingual dictionary. Such a specialized dictionary is useful not only for law students and for attorneys themselves, but for members of the lay public who require legal services. Legal dictionaries published in print follow the normal practice of sorting entry terms alphabetically, while electronic dictionaries, such as the online Dictionary of Law on Dictionary.com, allow direct, immediate access to a search term.
  • lenticular cloud — a very smooth, round or oval, lens-shaped cloud that is often seen, singly or stacked in groups, near a mountain ridge.
  • lesbian cymatium — cyma reversa.

  • lever escapement — an escapement in which a pivoted lever, made to oscillate by the escape wheel, engages a balance staff and causes it to oscillate.
  • lexical analyser — (language)   (Or "scanner") The initial input stage of a language processor (e.g. a compiler), the part that performs lexical analysis.
  • lexical analysis — (programming)   (Or "linear analysis", "scanning") The first stage of processing a language. The stream of characters making up the source program or other input is read one at a time and grouped into lexemes (or "tokens") - word-like pieces such as keywords, identifiers, literals and punctuation. The lexemes are then passed to the parser.

  • logical relation — A relation R satisfying f R g <=> For all a, b, a R b => f a R g b This definition, by Plotkin, can be used to extend the definition of a relation on the types of a and b to a relation on functions.
  • logical unit 6.2 — (networking)   (LU6.2) A type of logical unit that governs peer-to-peer SNA communications. LU6.2 supports general communication between programs in a distributed processing environment. LU6.2 is characterised by a peer relationship between session partners, efficient use of a session for multiple transactions, comprehensive end-to-end error processing and a generic application program interface consisting of structured verbs that are mapped into a product inplementation. LU6.2 is used by IBM's TPF operating system.
  • long-tail claims — Long-tail claims are claims that are made or settled a long time after the insurance policy has expired.
  • loop combination — A program transformation where the bodies of two loops are merged into one thus reducing the overhead of manipulating and testing the control variable and branching. Further optimisation of the merged code may then become possible. In horizontal loop combination the bodies of the loops are largely independent so only the loop overhead is saved. Vertical loop combination applies where the results of the first loop are used by the second. Combining the two allows the intermediate results to be used immediately (in registers) rather than requiring them to be stored in an array. The functional equivalent of horizontal and vertical loop combination are tupling and fusion.
  • lord chamberlain — (in Britain) the chief official of the royal household
  • lorenz attractor — (mathematics)   (After Edward Lorenz, its discoverer) A region in the phase space of the solution to certain systems of (non-linear) differential equations. Under certain conditions, the motion of a particle described by such as system will neither converge to a steady state nor diverge to infinity, but will stay in a bounded but chaotically defined region. By chaotic, we mean that the particle's location, while definitely in the attractor, might as well be randomly placed there. That is, the particle appears to move randomly, and yet obeys a deeper order, since is never leaves the attractor. Lorenz modelled the location of a particle moving subject to atmospheric forces and obtained a certain system of ordinary differential equations. When he solved the system numerically, he found that his particle moved wildly and apparently randomly. After a while, though, he found that while the momentary behaviour of the particle was chaotic, the general pattern of an attractor appeared. In his case, the pattern was the butterfly shaped attractor now known as the Lorenz attractor.
