  • aphrodite of melos — a Greek statue of Venus in marble, c200 b.c., found in 1820 on Melos and now in the Louvre, Paris.
  • apocryphal gospels — accounts of Christ's life that are not recognized as part of the New Testament
  • apparent solar day — the period of time between two successive passages of the sun's center across the same meridian.
  • application server — 1. A designer's or developer's suite of software that helps programmers isolate the business logic in their programs from the platform-related code. Application servers can handle all of the application logic and connectivity found in client-server applications. Many application servers also offer features such as transaction management, clustering and failover, and load balancing; nearly all offer ODBC support. 2. Production programs run on a mid-sized computer that handle all application operations between browser-based computers and an organisation's back-end business applications or databases. The application server works as a translator, allowing, for example, a customer with a browser to search an online retailer's database for pricing information. 3. The device on which application server software runs. Application Service Providers offer commercial access to such devices.

  • arctic archipelago — group of mostly large islands in the Arctic Ocean off the N coast of Canada
  • aristotelian logic — the logical theories of Aristotle as developed in the Middle Ages, concerned mainly with syllogistic reasoning: traditional as opposed to modern or symbolic logic
  • aristotles-lantern — a complex arrangement of muscles and calcareous teeth and plates forming an eversible organ in most echinoids, functioning in mastication.
  • arkansas toothpick — a bowie knife or similar sharp knifelike implement.
  • armed intervention — an official response to a situation which involves the armed forces
  • armed to the teeth — Someone who is armed to the teeth is armed with a lot of weapons or with very effective weapons.
  • army of occupation — an army that goes into a defeated country to enforce peace terms, keep order, etc.
  • arrest of judgment — a stay of proceedings after a verdict, on the grounds of error or possible error
  • arrogance of power — presumption on the part of a nation that its power gives it the right to intervene in the affairs of less powerful nations.
  • artificial horizon — an aircraft instrument, using a gyroscope, that indicates the aircraft's attitude in relation to the horizontal
  • as far as possible — to the greatest possible extent
  • asciibetical order — (jargon, programming)   /as'kee-be'-t*-kl or'dr/ Used to indicate that data is sorted in ASCII collated order rather than alphabetical order. The main difference is that, in ASCII, all the upper case letters come before any of the lower case letters so, e.g., "Z" comes before "a".
  • assessment process — a series of steps that constitute a method of assessing students or workers
  • assignment problem — (mathematics, algorithm)   (Or "linear assignment") Any problem involving minimising the sum of C(a, b) over a set P of pairs (a, b) where a is an element of some set A and b is an element of set B, and C is some function, under constraints such as "each element of A must appear exactly once in P" or similarly for B, or both. For example, the a's could be workers and the b's projects. The problem is "linear" because the "cost function" C() depends only on the particular pairing (a, b) and is independent of all other pairings.
  • associate director — a person who is joined with one or more other directors in an enterprise, business, etc, having equal or nearly equal status
  • association cortex — any of the regions of the cerebral cortex of the brain connected by numerous nerve fibers to all parts of both cerebral hemispheres and coordinating such higher activities as learning and reasoning.
  • associative cortex — the part of the cortex that does not have direct connections to the senses or motor system and is thought to be involved in higher mental processes
  • associative memory — content addressable memory
  • assortative mating — the reproductive pairing of individuals that have more traits in common than would likely be the case if mating were random (contrasted with disassortative mating).
  • assumption of risk — Assumption of risk is the practice of paying for minor losses yourself, but protecting against catastrophic losses by buying insurance cover.
  • ast computers, llc — (company)   The private company formed in January 1999 when Mr. Beny Alagem, the former chairman of Packard Bell NEC, Inc., bought the name and intellectual property of AST Research, Inc.. AST Computers, LLC provide hardware, software, and services for small US businesses. Address: Los Angeles, CA, USA.
  • astrological chart — map of constellations at certain time
  • astrometric binary — a binary star that can be recognized as such because of its undulating proper motion.
  • astronomical clock — a complex clock showing astronomical phenomena, such as the phases of the moon
  • asymptotic freedom — a property of the force between quarks, according to quantum chromodynamics, such that they behave almost like free particles when they are close together within a hadron.
  • asynchronous logic — (architecture)   A data-driven circuit design technique where, instead of the components sharing a common clock and exchanging data on clock edges, data is passed on as soon as it is available. This removes the need to distribute a common clock signal throughout the circuit with acceptable clock skew. It also helps to reduce power dissipation in CMOS circuits because gates only switch when they are doing useful work rather than on every clock edge. There are many kinds of asynchronous logic. Data signals may use either "dual rail encoding" or "data bundling". Each dual rail encoded Boolean is implemented as two wires. This allows the value and the timing information to be communicated for each data bit. Bundled data has one wire for each data bit and another for timing. Level sensitive circuits typically represent a logic one by a high voltage and a logic zero by a low voltage whereas transition signalling uses a change in the signal level to convey information. A speed independent design is tolerant to variations in gate speeds but not to propagation delays in wires; a delay insensitive circuit is tolerant to variations in wire delays as well. The purest form of circuit is delay-insensitive and uses dual-rail encoding with transition signalling. A transition on one wire indicates the arrival of a zero, a transition on the other the arrival of a one. The levels on the wires are of no significance. Such an approach enables the design of fully delay-insensitive circuits and automatic layout as the delays introduced by the layout compiler can't affect the functionality (only the performance). Level sensitive designs can use simpler, stateless logic gates but require a "return to zero" phase in each transition.
  • at a rate of knots — very fast
  • at boardroom level — among directors
  • at the risk of sth — If you do something at the risk of something unpleasant happening, you do it even though you know that the unpleasant thing might happen as a result.
  • at your fingertips — If you say that something is at your fingertips, you approve of the fact that you can reach it easily or that it is easily available to you.
