  5. The restoration of equilibrium following disturbance

  1. (physiology) the gradual lengthening of inactive muscle or muscle fibers
  2. (physics) the exponential return of a system to equilibrium after a disturbance
  3. easiness: a feeling of refreshing tranquility and an absence of tension or worry; "the easiness we feel when sleeping"
  4. an occurrence of control or strength weakening; "the relaxation of requirements"; "the loosening of his grip"; "the slackening of the wind"
  5. rest: freedom from activity (work or strain or responsibility); "took his repose by the swimming pool"
  6. a method of solving simultaneous equations by guessing a solution and then reducing the errors that result by successive approximations until all the errors are less than some specified amount
  7. In nuclear magnetic resonance (NMR) spectroscopy and magnetic resonance imaging (MRI) the term relaxation describes several processes by which nuclear magnetization prepared in a non-equilibrium state return to the equilibrium distribution. ...
  8. In the physical sciences, relaxation usually means the return of a perturbed system into equilibrium. Since the underlying microscopic processes are active even in the absence of external perturbations, one can also study "relaxation in equilibrium".
  9. In psychology, relaxation is the emotional state of low tension, in which there is an absence of arousal that could come from sources such as anger, anxiety, or fear.
  10. (Relaxing) Leisure or free time, is a period of time spent out of work and essential domestic activity. ...
  11. The act of relaxing or the state of being relaxed; the opposite of stress or tension; the aim of recreation and leisure activities; A diminution of tone, tension, or firmness; specifically in pathology: a looseness; a diminution of the natural and healthy tone of parts; Remission or abatement of ...
  12. (relaxable) Able to be relaxed; capable of being relaxed
  13. (relaxing) Having a quality whereby it is easy to relax when subjected to it
  14. (Relaxing) A term used to describe the expanding process of wallpaper after water or adhesive has been applied. Some wallpapers expand 1/2" to 1" during the 2 to 10 minutes following exposure to moisture.
  15. (Relaxing) A general term for allowing fabrics or yarns to find their most 'comfortable' configuration. These processes tend to involve immersion in large volumes of water to allow things to shrink and swell.
  16. (Relaxing) the opposite of demanding. Does the ski insist that you stay right on top of it, with no relaxation, or will it cover up and smooth over minor wobbles, glitches and bobbles? Is it possible to relax or does the ski demand constant high energy input?
  17. The loss of clamping force in a bolt that occurs typically without any nut rotation occurring. Commonly occurs as a result of embedment but can also be due to gasket creep, metal creep (at elevated temperatures), differential thermal expansion and stress relaxation.
  18. A term used to mean all irreversible processes which bring a system back to equilibrium after it has been perturbed by some external force. ...
  19. Process in which an artificial neural network reaches a state of stable activations.
  20. The process of gravitational interaction (in the case of a cluster of stars or galaxies) whereby a random distribution of motions is eventually established. The system is said to relax to a state of thermal equilibrium. [Silk90]
  21. Whenever polymer melts are subjected to mechanical work they develop stresses which do not become immediately zero when the mechanical influence is removed. The time required for the stresses to relax is referred to as RELAXATION TIME. ...
  22. A change in net magnetization over time.
  23. Passage of an excited or otherwise perturbed system towards or into thermal equilibrium with its environment.  [IUPAC Photochemistry] Narrower term: chemical relaxation
  24. Loss of species in a given location after the area has been cut off from exchange with neighboring areas. (1)
  25. Relative minimal arousal. Calmness. Lack of anxiety, or stress. See Systematic Desensitization.
