linkage (mechanism)
Science; General science
A set of rigid bodies, called links, joined together at pivots by means of pins or equivalent devices. A body is considered to be rigid if, for practical purposes, the distances ...
pulse modulation
Science; General science
A set of techniques whereby a sequence of information-carrying quantities occurring at discrete instances of time is encoded into a corresponding regular sequence of ...
supersaturation
Science; General science
A solution is at the saturation point when dissolved solute in it crystallizes from it at the same rate at which it dissolves. Under prescribed experimental conditions of ...
Green's function
Science; General science
A solution of a partial differential equation for the case of a point source of unit strength within the region under examination. The Green's function is an important ...
azeotropic mixture
Science; General science
A solution of two or more liquids, the composition of which does not change upon distillation. The composition of the liquid phase at the boiling point is identical to that of ...
instanton
Science; General science
A solution to the (imaginary-time) nonlinear field equation which arises in Yang-Mills field theory—a modern nonlinear generalization of Maxwell electromagnetic theory that is ...
focused sonic booms
Science; General science
A sonic boom is the loud impulsive sound produced by any object moving faster than the local sound speed. Human-made sonic booms have existed for a long time, due to cracking ...
