defined for each point x in the domain of the function by \inf\left\{\mathrm{diam}(f(U))\mid U\mathrm{\ is\ a\ neighborhood\ of\ }x\right\}, and describes the difference (possibly ∞) between the limit superior and limit inferior of the function near that point
A periodic motion backward and forward To vibrate or vary above and below a mean value
The travel of the balance wheel from one extreme to the other and back again See Vibration
The variation, usually with time, of the magnitude of quantity with respect to a specified reference when the magnitude is alternately greater and smaller than the reference
a single complete execution of a periodically repeated phenomenon; "a year constitutes a cycle of the seasons"
The natural frequency at which almost every physical system moves when disturbed from rest; it can be free or forced See also resonance and seiche
Variation with time of a quantity such as force, stress, pressure, displacement, velocity, acceleration or jerk Usually implies some regularity (as in sinusoidal or complex vibration)
Uneven wrap in coiling and lateral travel during winding Improper alignment of rolls over which the metal passes before rewinding and insufficient rewind tension are typical causes See also "Telescoping "
Variation with time of a quantity such as F, stress, pressure, x, v, a or jerk Usually implies some regularity (as in sinusoidal or complex vibration)
Motion of balance from one position of maximum displacement to the next and the return to original position
