  • partial equivalence relation — (PER) A relation R on a set S where R is symmetric (x R y => y R x) and transitive (x R y R z => x R z) and where there may exist elements in S for which the relation is not defined. A PER is an equivalence relation on the subset for which it is defined, i.e. it is also reflexive (x R x).

  • plug compatible manufacturer — (company)   (PCM) A manufacturer of equipment that some other manufacturer's system can identify and work with. The PCM's device replaces the original manufacturer's. Most PCMs competed with IBM. PCM devices normally offer a cost-performance benefit over the original device. For example, several PCM versions of the Direct-Access Storage Device IBM 3350 offered twice the storage and improved data access (dual port). Plug compatible devices include replacement CPUs, such as the Hitachi 7/90 series (which could be substituted for IBM 3090 series processors), I/O subsystems, and dumb terminals like the IBM 3270.
  • potassium antimonyl tartrate — a white, water-soluble, sweet and metallic-tasting, poisonous powder or granules, C 4 H 4 KO 7 Sb, used as a mordant for dyeing textiles and leather, and in medicine as an expectorant, for inducing vomiting, and for infections by schistosomes.
  • principle of complementarity — complementarity principle.
  • probability density function — a function of a continuous variable whose integral over a region gives the probability that a random variable falls within the region.
  • put one's cards on the table — a usually rectangular piece of stiff paper, thin pasteboard, or plastic for various uses, as to write information on or printed as a means of identifying the holder: a 3″ × 5″ file card; a membership card.
  • quick mail queueing protocol — (communications)   (QMQP) A protocol that provides a central e-mail queue for a cluster of hosts. QMOP is supposed to provide fast transfers of messages with many recipients as it can batch them up as a single transaction. It listens on port 628.
  • quick mail transfer protocol — (communications)   (QMTP) An SMTP replacement that works better over high latency links as it doesn't require as much interaction as SMTP. QMTP listens on port 209 and is used by qmail.
  • raise specification language — (language)   (RSL) (RAISE = Rigorous Approach to Industrial Software Engineering). A wide-spectrum specification and design language developed by ESPRIT Project 315 at CRI A/S, Denmark. Systems may be modular, concurrent and nondeterministic. Specifications may be applicative or imperative, explicit or implicit, abstract or concrete.
  • real time streaming protocol — (multimedia, networking, protocol)   (RTSP) An application layer protocol for controlling delivery of a stream of real-time multimedia content. RTSP allows users to start playing from a certain position. It does not actually deliver the data, but works alongside existing delivery channels such as UDP, TCP, or IP multicast. RTSP was developed by RealNetworks, Netscape Communications, and Columbia University, and is described in RFC 2326, April 1998. RTSP is an IETF proposed standard.
  • real-estate investment trust — an unincorporated trust created for the purpose of investing in real property or to extend credit to those engaged in construction. Abbreviation: REIT.
  • real-time transport protocol — (protocol)   (RTP) An Internet protocol for transmitting real-time data such as audio and video. RTP itself does not guarantee real-time delivery of data, but it does provide mechanisms for the sending and receiving applications to support streaming data. Typically, RTP runs on top of the UDP protocol, although the specification is general enough to support other transport protocols. RTP has received wide industry support. Netscape intends to base its LiveMedia technology on RTP, and Microsoft claims that its NetMeeting product supports RTP.

  • second law of thermodynamics — any of three principles variously stated in equivalent forms, being the principle that the change of energy of a thermodynamic system is equal to the heat transferred minus the work done (first law of thermodynamics) the principle that no cyclic process is possible in which heat is absorbed from a reservoir at a single temperature and converted completely into mechanical work (second law of thermodynamics) and the principle that it is impossible to reduce the temperature of a system to absolute zero in a finite number of operations (third law of thermodynamics)
  • self-regulating organization — one of several British organizations set up in 1986 under the auspices of the Securities and Investment Board to regulate the activities of London investment markets
  • semiconservative replication — replication.

  • single sideband transmission — a method of transmitting radio waves in which either the upper or the lower sideband is transmitted, the carrier being either wholly or partially suppressed. This reduces the required bandwidth and improves the signal-to-noise ratio
  • smooth endoplasmic reticulum — a network of tubular membranes within the cytoplasm of the cell, occurring either with a smooth surface (smooth endoplasmic reticulum) or studded with ribosomes (rough endoplasmic reticulum) involved in the transport of materials.
  • special power of appointment — authority to appoint persons from a particular class to take an estate or interest in property
  • spectral luminous efficiency — a measure of the efficiency of radiation of a given wavelength in producing a visual sensation. It is equal to the ratio of the radiant flux at a standard wavelength to that at the given wavelength when the standard wavelength is chosen so that the maximum value of this ratio is unity
  • strictly decreasing function — a function having the property that for any two points in the domain such that one is larger than the other, the image of the larger point is less than the image of the smaller point.
  • strictly increasing function — a function having the property that for any two points in the domain such that one is larger than the other, the image of the larger point is greater than the image of the smaller point.
