__NOTOC__ Decoupling usually refers to the ending, removal or reverse of

coupling A coupling is a device used to connect two shafts together at their ends for the purpose of transmitting power. The primary purpose of couplings is to join two pieces of rotating equipment while permitting some degree of misalignment or end mov ...

Decoupling (advertising) Decoupling, in advertising, occurs when services that were previously subcontracted by advertising agencies are purchased directly from suppliers. Decoupling is part of the unbundling of the services previously provided by traditional full serv ...

Decoupling (utility regulation) In public utility regulation, decoupling refers to the disassociation of a utility's profits from its sales of the energy commodity. Instead, a rate of return is aligned with meeting revenue targets, and rates are adjusted up or down to meet the t ...

Decoupling and re-coupling Economics Decoupling and re-coupling during financial crises is typified by the decoupling hypothesis that, in 2007, held that Latin American and Asian economies, especially emerging ones, had broadened and deepened to the point that they no lo ...

Decoupling (organizational studies) In organizational studies, and particularly new institutional theory, decoupling is the creation and maintenance of gaps between formal policies and actual organizational practices.Meyer, John W., and Brian Rowan. 1977. "Institutionalized Organiz ...

Decoupling of wages from productivity The decoupling of wages from productivity, sometimes known as the great decoupling, is the gap between the growth rate of median wages and the growth rate of GDP. Economists began to acknowledge this problem toward the end of the twentieth century ...

Eco-economic decoupling In economic and environmental fields, decoupling refers to an economy that would be able to grow without corresponding increases in environmental pressure. In many economies, increasing production (GDP) currently raises pressure on the environme ...

Decoupling (cosmology) In cosmology, decoupling refers to a period in the development of the universe when different types of particles fall out of thermal equilibrium with each other. This occurs as a result of the expansion of the universe, as their interaction rate ...

Decoupling (meteorology) In weather forecasting, decoupling is boundary-layer decoupling of atmospheric layers over land at night. During the day when the sun shines and warms the land, air at the surface of the earth is heated and rises. This rising air mixes the atmos ...

Nuclear magnetic resonance decoupling Nuclear magnetic resonance decoupling (NMR decoupling for short) is a special method used in nuclear magnetic resonance (NMR) spectroscopy where a sample to be analyzed is irradiated at a certain frequency or frequency range to eliminate fully o ...

Decoupling (probability) In probability and statistics, decoupling is a reduction of a sample statistic to an average of the statistic evaluated on several independent sequences of the random variable. This sum, conditioned on all but one of the independent sequences, ...

Decoupling for body-focused repetitive behaviors Decoupling is a behavioral self-help intervention developed for body-focused and related behaviors (DSM-5) such as trichotillomania, onychophagia ( nail biting), skin picking and lip-cheek biting. The user is instructed to modify the original d ...

Decoupling (electronics) In electronics, decoupling is the prevention of undesired coupling between subsystems. A common example is connecting localized decoupling capacitors close to the power leads of integrated circuits to suppress coupling via the power supply c ...
