  • functional database — (database, language)   A database which uses a functional language as its query language. Databases would seem to be an inappropriate application for functional languages since, a purely functional language would have to return a new copy of the entire database every time (part of) it was updated. To be practically scalable, the update mechanism must clearly be destructive rather than functional; however it is quite feasible for the query language to be purely functional so long as the database is considered as an argument. One approach to the update problem would use a monad to encapsulate database access and ensure it was single threaded. Alternative approaches have been suggested by Trinder, who suggests non-destructive updating with shared data structures, and Sutton who uses a variant of a Phil Wadler's linear type system. There are two main classes of functional database languages. The first is based upon Backus' FP language, of which FQL is probably the best known example. Adaplan is a more recent language which falls into this category. More recently, people have been working on languages which are syntactically very similar to modern functional programming languages, but which also provide all of the features of a database language, e.g. bulk data structures which can be incrementally updated, type systems which can be incrementally updated, and all data persisting in a database. Examples are PFL [Poulovassilis&Small, VLDB-91], and Machiavelli [Ohori et al, ACM SIGMOD Conference, 1998].
  • functional language — (language)   A language that supports and encourages functional programming.
  • functional medicine — individualized medical care that recognizes the interactions between genetic and environmental factors and between the body's interconnected systems.

  • genetic programming — (programming)   (GP) A programming technique which extends the genetic algorithm to the domain of whole computer programs. In GP, populations of programs are genetically bred to solve problems. Genetic programming can solve problems of system identification, classification, control, robotics, optimisation, game playing, and pattern recognition. Starting with a primordial ooze of hundreds or thousands of randomly created programs composed of functions and terminals appropriate to the problem, the population is progressively evolved over a series of generations by applying the operations of Darwinian fitness proportionate reproduction and crossover (sexual recombination).
  • geneva nomenclature — an internationally accepted system for naming organic carbon compounds.
  • geocentric parallax — the apparent displacement of an observed object due to a change in the position of the observer.
  • geomagnetic equator — an imaginary line on the earth's surface, the plane of which passes through the center and is midway between the geomagnetic poles.
  • gestational carrier — surrogate mother (def 3).
  • gigabits per second — (unit)   (Gbps) A unit of information transfer rate equal to one billion bits per second. Note that, while a gigabit is defined as a power of two (2^30 bits), a gigabit per second is defined as a power of ten (10^9 bits per second, which is slightly less) than 2^30).
  • glottalic airstream — a current of air in the pharynx produced by the action of the glottis.
  • goldbach conjecture — an unproved theorem that every even integer greater than 2 can be written as the sum of two prime numbers.
  • grandfather's clock — a pendulum floor clock having a case as tall as or taller than a person; tall-case clock; long-case clock.
  • grandmother's clock — a pendulum clock similar to a grandfather's clock but shorter.
  • great wall of china — a system of fortified walls with a roadway along the top, constructed as a defense for China against the nomads of the regions that are now Mongolia and Manchuria: completed in the 3rd century b.c., but later repeatedly modified and rebuilt. 2000 miles (3220 km) long.
  • gregorian telescope — a telescope similar in design to the Cassegrainian telescope but less widely used.
  • grievance committee — a group of representatives chosen from a labor union or from both labor and management to consider and remedy workers' grievances.
  • grocer's apostrophe — an apostrophe placed before a final s intended to indicate the plural but in fact forming the possessive

  • historic episcopate — the derivation of the episcopate of a Church in historic succession from the apostles
  • holy innocents' day — December 28, a day of religious observance commemorating the slaughter of the children of Bethlehem by Herod's order.
  • horizontal encoding — (processor)   An instruction set where each field (a bit or group of bits) in an instruction word controls some functional unit or gate directly, as opposed to vertical encoding where instruction fields are decoded (by hard-wired logic or microcode) to produce the control signals. Horizontal encoding allows all possible combinations of control signals (and therefore operations) to be expressed as instructions whereas vertical encoding uses a shorter instruction word but can only encode those combinations of operations built into the decoding logic. An instruction set may use a mixture of horizontal and vertical encoding within each instruction. Because an architecture using horizontal encoding typically requires more instruction word bits it is sometimes known as a very long instruction word (VLIW) architecture.
  • hospital facilities — the equipment and services provided by a hospital
  • hotel accommodation — the facilities and the quality of accommodation provided by a hotel
