71relaxation phenomenon — ▪ physics and chemistry Introduction in physics and chemistry, an effect related to the delay between the application of an external stress to a system that is, to an aggregation of matter and its response. It may occur in nuclear, atomic,… …
72Relaxation (NMR) — 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. In… …
73Relaxation (physics) — In the physical sciences, relaxation usually means the return of a perturbed system into equilibrium. Each relaxation process can be characterized by a relaxation time τ. The simplest theoretical description of relaxation as function of time t is …
74Relaxation (NMR) — Unter Relaxation versteht man in der Kernspinresonanzspektroskopie (NMR Spektroskopie) und Magnetresonanztomographie (MRT) die Vorgänge, die die Kernspin Magnetisierung (z. B. nach einer Auslenkung oder Anregung) in ihren… …
75Relaxation (approximation) — In mathematical optimization and related fields, relaxation is a modeling strategy. A relaxation is an approximation of a difficult problem by a nearby problem that is easier to solve. A solution of the relaxed problem provides information about… …
76Relaxation technique — A Relaxation technique (also known as Relaxation training) is any method, process, procedure, or activity that helps a person to relax; to attain a state of increased calmness; or otherwise reduce levels of anxiety, stress or tension. Relaxation… …
77relaxation drink — n. A nonalcoholic drink formulated to help promote relaxation and relieve stress. relaxation drink adj. Example Citations: While energy drinks are a very competitive segment of the beverage market, he said, Chillo which has a slight hint of… …
78Relaxation technique (mathematics) — A relaxation technique is a method in mathematical optimization for relaxing a strict requirement, by either substituting for it another more easily handled requirement or else dropping it completely. Relaxation techniques are commonly used in… …
79Relaxation method — In numerical mathematics, the relaxation method is a method for obtaining numerical approximations to the solutions of systems of equations, including certain types of elliptic partial differential equations, in particular Laplace s equation and… …
