  • magnetic hysteresis — hysteresis in a ferromagnetic material; the lag in the response of magnetic induction to changes of magnetic intensity.
  • 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.
  • megabits per second — (unit)   (Mbps, Mb/s) Millions of bits per second. A unit of data rate. 1 Mb/s = 1,000,000 bits per second (not 1,048,576). E.g. Ethernet can carry 10 Mbps.
  • molecular biologist — a specialist in the study of biological phenomena at the molecular level
  • negative resistance — a characteristic of certain electronic components in which an increase in the applied voltage increases the resistance, producing a proportional decrease in current
  • no strings attached — without conditions
  • noughts and crosses — tick-tack-toe (def 1).
  • noughts-and-crosses — tick-tack-toe (def 1).
  • orthopaedic surgeon — a surgeon specializing in the branch of surgery concerned with disorders of the spine and joints and the repair of deformities of these parts
  • orthopaedic surgery — surgery concerned with disorders of the spine and joints and the repair of deformities of these parts
  • oscillating circuit — a circuit producing electrical oscillations.
  • parallel processing — extending in the same direction, equidistant at all points, and never converging or diverging: parallel rows of trees.
  • pastoral counseling — the use of psychotherapeutic techniques by trained members of the clergy to assist parishioners who seek help for personal or emotional problems.

  • performance figures — the statistics that indicate how well or badly a company or organization has performed
  • performance targets — the expected or predicted success level of an individual, company or organization
  • physical addressing — (networking)   The low level addressing scheme used on Ethernet. The 48-bit destination Ethernet address in a packet is compared with the receiving node's Ethernet address. Compare IP address.
  • pneumogastric nerve — the vagus nerve.
  • prescription charge — a charge, set by the government, to be paid by a patient for medicines
  • 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.
  • propositional logic — (logic)   (or "propositional calculus") A system of symbolic logic using symbols to stand for whole propositions and logical connectives. Propositional logic only considers whether a proposition is true or false. In contrast to predicate logic, it does not consider the internal structure of propositions.
  • pseudo-biographical — of or relating to a person's life: He's gathering biographical data for his book on Milton.
  • pugwash conferences — international peace conferences of scientists held regularly to discuss world problems: Nobel peace prize 1995 awarded to Joseph Rotblat (1908–2005) , one of the founders of the conferences, secretary-general (1957–73), and president (1988–97)
  • quick-change artist — a person adept at changing from one thing to another, as an entertainer who changes costumes quickly during a performance.

  • recording secretary — an officer charged with keeping the minutes of meetings and responsible for the records.
  • register allocation — (compiler, algorithm)   The phase of a compiler that determines which values will be placed in registers. Register allocation may be combined with register assignment. This problem can be shown to be isomorphic to graph colouring by relating values to nodes in the graph and registers to colours. Values (nodes) which must be valid simultaneously are linked by edges and cannot be stored in the same register (coloured the same). See also register dancing and register spilling.
