  • 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.
  • process engineering — the branch of engineering concerned with industrial processes, esp continuous ones, such as the production of petrochemicals
  • psychoendocrinology — the study of the relationship between the endocrine system and various symptoms or types of mental illness.

  • 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.
  • register assignment — (compiler, algorithm)   The phase of a compiler that determines which register to use for each program value selected during register allocation.
  • registration number — number on vehicle licence plate
  • regression analysis — Statistics. a procedure for determining a relationship between a dependent variable, as predicted success in college, and an independent variable, as a score on a scholastic aptitude test, for a given population. The relationship is expressed as an equation for a line (regres·sion·line) or curve (regres·sion·curve) in which any coefficient (regression coefficient) of the independent variable in the equation has been determined from a sample population.
  • regular icosahedron — an icosahedron in which each of the faces is an equilateral triangle
  • releasing mechanism — a hypothetical control complex in the central nervous system of animals that triggers the appropriate behavioral response to a releaser.
  • religious education — religion as school subject

  • resistance training — physical training that utilizes isometric, isotonic, or isokinetic exercise to strengthen or develop the muscles.
  • resonant-jet engine — resojet engine.
  • respiratory pigment — any of several colored protein substances, as hemoglobin and hemocyanin, in the circulatory system of animals and some plants, that combine reversibly with oxygen that is carried to the tissues
  • reverse engineering — (systems, product, design)   The process of analysing an existing system to identify its components and their interrelationships and create representations of the system in another form or at a higher level of abstraction. Reverse engineering is usually undertaken in order to redesign the system for better maintainability or to produce a copy of a system without access to the design from which it was originally produced. For example, one might take the executable code of a computer program, run it to study how it behaved with different inputs and then attempt to write a program which behaved identically (or better). An integrated circuit might also be reverse engineered by an unscrupulous company wishing to make unlicensed copies of a popular chip.
  • 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
