  • 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.
  • meningoencephalitic — Relating to meningoencephalitis.
  • meningoencephalitis — Inflammation of the membranes of the brain and the adjoining cerebral tissue.
  • multiplication sign — Arithmetic. the symbol (⋅), (×), or (∗) between two mathematical expressions, denoting multiplication of the second expression by the first. In certain algebraic notations the sign is suppressed and multiplication is indicated by immediate juxtaposition or contiguity, as in ab.
  • nagling coalescence — (networking, algorithm)   An algorithm for improving TCP/IP network performance by combining small packets ("tinygrams") into larger ones, thus reducing the per-packet overhead. The server transmits the packet either when it has reached a preset size or when it receives an acknowledgment of the previous packet.
  • negative income tax — a system of income subsidy through which persons having less than a certain annual income receive money from the government rather than pay taxes to it.
  • neighbourhood watch — a scheme under which members of a community agree together to take responsibility for keeping an eye on each other's property, as a way of preventing crime
  • neuropathologically — In a neuropathologic way.
  • no strings attached — without conditions
  • not care/give a fig — If you say that someone doesn't care a fig or doesn't give a fig about something, you are emphasizing that they think it is unimportant or that they are not interested in it.
  • occupation grouping — a category in a system of classifying people according to occupation, based originally on information obtained by government census and subsequently developed by market research. The classifications are used by the advertising industry to identify potential markets. The groups are A, B, C1, C2, D, and E
  • 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
  • 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.
  • parthenogenetically — development of an egg without fertilization.
  • particle technology — Particle technology is knowledge and study which relates to particles, and is used in industry.
  • pastoral counseling — the use of psychotherapeutic techniques by trained members of the clergy to assist parishioners who seek help for personal or emotional problems.

  • prescription charge — a charge, set by the government, to be paid by a patient for medicines
  • 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.
  • psychological novel — a novel that focuses on the complex mental and emotional lives of its characters and explores the various levels of mental activity.

  • radiational cooling — the cooling of the earth's surface and adjacent air, primarily at night, caused by a loss of heat due to surface emission of infrared radiation.
  • reciprocal exchange — an unincorporated association formed so that its members can participate in reciprocal insurance.
  • reciprocal leveling — leveling between two widely separated points in which observations are made in both directions to eliminate the effects of atmospheric refraction and the curvature of the earth.
  • 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.
  • regular icosahedron — an icosahedron in which each of the faces is an equilateral triangle
  • religious education — religion as school subject
  • rhodesian ridgeback — a large short-haired breed of dog characterized by a ridge of hair growing along the back in the opposite direction to the rest of the coat. It was originally a hunting dog from South Africa

  • rocky mountain goat — a long-haired, white, antelopelike wild goat, Oreamnos americanus, of mountainous regions of western North America, having short, black horns.
  • sandwich generation — the generation of people still raising their children while having to care for their aging parents.
  • saturation coverage — news coverage (of an event, etc) that is very thorough in order not to miss any details
  • scattersite housing — public housing, especially for low-income families, built throughout an urban area rather than being concentrated in a single neighborhood.
  • screen actors guild — a labor union for motion-picture performers, founded in 1933. Abbreviation: SAG.
