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
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
— a repetitive movement or change that alternates between two states or extremes, each of which represents a minimum or a maximum value
{i} act of something which oscillates; regular pendulation between two positions; vacillation between two opinions; fluctuation between high and low values; wavering between two extremes
(physics) a regular periodic variation in value about a mean the process of oscillating between states
The movement to and fro between two points Also the swinging between two points such as pendulum
The rate at which an electric toothbrush head moves back and forth or spins The higher the speed the more advanced the cleaning capability and stain removal
An oscillation, as it applies to microgravity experiments, is a vibration However, oscillations can refer to any steady back and forth movements
a more intense El Nino that occurs every few years when the welling up of cold nutrient-rich water does not occur; kills plankton and fish and affects weather patterns
If an object oscillates, it moves repeatedly from one position to another and back again, or keeps getting bigger and smaller. I checked to see if the needle indicating volume was oscillating. + oscillation oscillations os·cil·la·tion Some oscillation of the fuselage had been noticed on early flights
{f} vary regularly between two positions; vacillate between two opinions; fluctuate between high and low values; swing predictably between two extremes
If the level or value of something oscillates between one amount and another, it keeps going up and down between the two amounts. Oil markets oscillated on the day's reports from Geneva. an oscillating signal of microwave frequency. = fluctuate + oscillation oscillations os·cil·la·tion There have always been slight oscillations in world temperature
If you oscillate between two moods, attitudes, or types of behaviour, you keep changing from one to the other and back again. The president of the Republic oscillated between a certain audacity and a prudent realism. + oscillation os·cil·la·tion that perpetual oscillation between despair and distracted joy
be undecided about something; waver between conflicting positions or courses of action; "He oscillates between accepting the new position and retirement"
