Intermittency In dynamical systems, intermittency is the irregular alternation of phases of apparently periodic and chaotic dynamics ( Pomeau–Manneville dynamics), or different forms of chaotic dynamics (crisis-induced intermittency). Pomeau and Manne ...

is a behavior of dynamical systems: regular alternation of phases of apparently periodic and chaotic dynamics. Intermittent or intermittency may also refer to: *

Intermittent river Intermittent, temporary or seasonal rivers or streams cease to flow every year or at least twice every five years.(Tzoraki et al., 2007) Such rivers drain large arid and semi-arid areas, covering approximately a third of the earth's surface. ...

or stream, the one that ceases to flow every year or at least twice every five years * Intermittent energy source, renewable energy sources that are not dispatchable due to their fluctuating nature *

Intermittent fault An intermittent fault, often called simply an "intermittent", (or anecdotally "interfailing") is a malfunction of a device or system that occurs at intervals, usually irregular, in a device or system that functions normally at other times. Intermitt ...

Fluorescence intermittency Fluorescence intermittency, or blinking, is the phenomenon of random switching between ON (bright) and OFF (dark) states of the emitter under its continuous excitation. It is a common property of the nanoscale emitters (molecular fluorophores, coll ...
