- portuguese guinean — of or relating to Portuguese Guinea, a former name for Guinea-Bissau, or its inhabitants
- prepare the ground — make conditions ready
- principal argument — the radian measure of the argument between −π and π of a complex number. Compare argument (def 8c).
- procrustean string — (programming) A fixed-length string. If a string value is too long for the allocated space, it is truncated to fit; and if it is shorter, the empty space is padded, usually with space characters. This is an allusion to Procrustes, a legendary robber of ancient Attica. He bound his victims to a bed, and if they were shorter than the bed, he stretched their limbs until they would fit; if their limbs were longer, he lopped them off.

- radius of gyration — the distance from an axis at which the mass of a body may be assumed to be concentrated and at which the moment of inertia will be equal to the moment of inertia of the actual mass about the axis, equal to the square root of the quotient of the moment of inertia and the mass.
- reciprocating pump — A reciprocating pump is a pump which uses a backward and forward movement to move a fluid.
- recruiting officer — a person whose job is to recruit staff, esp on behalf of the military

- reduction strategy — (theory) An algorithm for deciding which redex(es) to reduce next. Different strategies have different termination properties in the presence of recursive functions or values. See string reduction, normal order reduction, applicative order reduction, parallel reduction
- reference counting — (programming) A garbage collection technique where each memory cell contains a count of the number of other cells which point to it. If this count reaches zero the cell is freed and its pointers to other cells are followed to decrement their counts, and so on recursively. This technique cannot cope with circular data structures. Cells in such structures refer (indirectly) to themselves and so will never have a zero reference count. This means they would never be reclaimed, even when there are no references from outside the structure.
- residual magnetism — remanence.
- rule of engagement — a directive issued by a military authority controlling the use and degree of force, especially specifying circumstances and limitations for engaging in combat.
- run length limited — (storage) (RLL) The most popular scheme for encoding data on magnetic disks. RLL packs up to 50% more data on a disk than MFM. Groups of bits are mapped to specific patterns of flux. The density of flux transitions is limited by the spatial resolution of the disk and frequency response of the head and electronics. However, transitions must be close enough to allow reliable clock recovery. RLL implementations vary according to the minimum and maximum allowed numbers of transition cells between transitions. For example, the most common variant today, RLL 1,7, can have a transition in every other cell and must have at least one transition every seven cells. The exact mapping from bits to transitions is essentially arbitrary. Other schemes include GCR, FM, Modified Frequency Modulation (MFM). See also: PRML.
- runge-kutta method — a numerical method, involving successive approximations, used to solve differential equations.
- running commentary — non-stop description of sth
