kopplade

Kopplade is a Swedish term meaning "coupled" or "connected." It functions as the past participle or adjective of the verb koppla, "to connect." In Swedish technical writing, kopplade describes systems, components, or variables that influence each other directly or indirectly, producing a combined behavior that cannot be understood by considering the parts in isolation.

In physics and engineering, a kopplad system contains interacting elements that exchange energy or information. Examples include coupled oscillators such as pendulums or LC circuits, mechanical linkages and gear trains, and electrical systems with mutual inductance or transformers. The degree of coupling is described by a coupling coefficient or strength, and strong coupling tends to create collective modes while weak coupling allows near-independent behavior.

In computing and data architecture, kopplade components are those with tight coupling, where changes in one element require changes in another. Loose coupling is preferred in modular design to enhance flexibility and testability. In data contexts, kopplade data or linked data describes relationships between datasets that are joined or interoperable.

In linguistics and social sciences, kopplade may refer to observed associations between variables or concepts, where correlation implies a linked behavior rather than a causal assertion.
