  • 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.
  • graphic workstation — (graphics, computer)   A workstation specifically configured for graphics works such as image manipulation, bitmap graphics ("paint"), and vector graphics ("draw") type applications. Such work requires a powerful CPU and a high resolution display. A graphic workstation is very similar to a CAD workstation and, given the typical specifications of personal computers currently available in 1999, the distinctions are very blurred and are more likely to depend on availability of specific software than any detailed hardware requirements.
  • 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.
  • grocer's apostrophe — an apostrophe placed before a final s intended to indicate the plural but in fact forming the possessive
  • heel-and-toe racing — race walking.
  • hermitian conjugate — adjoint (def 2).
  • historiographically — In a historiographical manner; by means of a historiography.
  • honorable discharge — a discharge from military service of a person who has fulfilled obligations efficiently, honorably, and faithfully.
  • 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.
  • human rights record — the facts that are known about the tendency of a country, regime, etc, to observe and protect human rights
  • huntington's chorea — a hereditary disease of the central nervous system characterized by brain deterioration and loss of control over voluntary movements, the symptoms usually appearing in the fourth decade of life.
  • hyperbolic geometry — the branch of non-Euclidean geometry that replaces the parallel postulate of Euclidean geometry with the postulate that two distinct lines may be drawn parallel to a given line through a point not on the given line.
  • induction hardening — a process in which the outer surface of a metal component is rapidly heated by means of induced eddy currents. After rapid cooling the resulting phase transformations produce a hard wear-resistant skin
  • inorganic chemistry — the branch of chemistry dealing with inorganic compounds.
  • john c breckinridge — John Cabell, 1821–75, vice president of the U.S. 1857–61: Confederate general in the American Civil War.
  • lightning conductor — A lightning conductor is a long thin piece of metal on top of a building that attracts lightning and allows it to reach the ground safely.
  • logical shift right — logical shift
  • magnetic north pole — the point on Earth to where a compass needle points, and which is situated near the geographic North Pole. However, with time, the exact location can vary.
  • magnetohydrodynamic — Of or pertaining to magnetohydrodynamics.
  • malice aforethought — a predetermination to commit an unlawful act without just cause or provocation (applied chiefly to cases of first-degree murder).
  • manchester encoding — (communications, protocol)   A method of transmitting bits which enables the receiver to easily synchronise with the sender. A simple way of signalling bits might be to transmit a high voltage for some period for a 1-bit and a low voltage for a 0 bit: Bits Sent: 1 1 0 0 Signal: High ___ Low |___ Time: -> . . . . . However, when several identical bits are sent in succession, this provides no information to the receiver about when each bit starts and stops. Manchester encoding splits each bit period into two, and ensures that there is always a transition between the signal levels in the middle of each bit. This allows the receiver to synchronise with the sender. In normal Manchester encoding, a 1-bit is transmitted with a high voltage in the first period, and a low voltage in the second, and vice verse for the 0 bit: Bits Sent: 1 1 0 0 Signal: High Low || |_| || Time: -> . ' . ' . ' . ' . In Differential Manchester encoding, a 1-bit is indicated by making the first half of the signal equal to the last half of the previous bit's signal and a 0-bit is indicated by making the first half of the signal opposite to the last half of the previous bit's signal. That is, a zero bit is indicated by a transition at the beginning of the bit. Like normal Manchester encoding, there is always a transition in the middle of the transmission of the bit. Differential Manchester Encoding Bits Sent: 1 1 0 0 Signal: High __ Low |_| || || Time: -> . ' . ' . ' . ' . With each bit period half as long, twice as much bandwidth is required when using either of the Manchester encoding schemes.

  • nerve growth factor — a protein that promotes the growth, organization, and maintenance of sympathetic and some sensory nerve cells. Abbreviation: NGF.

  • prescription charge — a charge, set by the government, to be paid by a patient for medicines
  • priority scheduling — (operating system)   Processes scheduling in which the scheduler selects tasks to run based on their priority as opposed to, say, a simple round-robin. Priorities may be static or dynamic. Static priorities are assigned at the time of creation, while dynamic priorities are based on the processes' behaviour while in the system. For example, the scheduler may favour I/O-intensive tasks so that expensive requests can be issued as early as possible. A danger of priority scheduling is starvation, in which processes with lower priorities are not given the opportunity to run. In order to avoid starvation, in preemptive scheduling, the priority of a process is gradually reduced while it is running. Eventually, the priority of the running process will no longer be the highest, and the next process will start running. This method is called aging.
  • programmer's switch — (hardware)   A button on the front of some Apple Macintosh computers which, when pressed, causes a command line prompt to appear. This gives access to the built-in mini-debugger, which has commands to dump memory, return to the application that was broken out, and others. A more sophisticated debugger must be installed in order to inspect breakpoints, etc.
