"close coupling" is correct and can be used in written English.
It is usually used in the context of two or more things being connected, usually in a tight or efficient way. For example, "This computer system has a close coupling architecture for maximum efficiency."
Sticking fractions can be determined by molecular dynamics, perturbation and effective Hamiltonian theories, close coupling wave packet, and reduced density matrix approaches, or by the much more approximate soft-cube method.
Close coupling of computer simulations with experiments is an important approach for developing new knowledge of nuclear materials.
Close coupling is observed between discrete crack growth rates and oxidation layer growth rates in axial direction.
The close coupling between land and water resources makes an interdisciplinary research is essential this is particularly evident in the drinking water supply.
Smart Items are physical objects that are equipped with embedded computing units to enable close coupling of the real world to backend information systems.
Tools and methods are available for developing inherently safer process and carrying out waste minimization analysis individually without taking into account the close coupling between them.
The main challenges and future research directions are presented, while highlighting the close coupling of the MAC protocol design with the other layers of the protocol stack.
For these, and related technological challenges, close coupling of basic material and wide bandgap semiconductor science to device design and fabrication is required.
This close coupling enables easy digitalisation of the information from the geomorphological map into the GIS database for use in both scientific and practical applications.
A very close coupling exists between changes in atmospheric O2 and CO2 concentrations, owing to the chemistry of photosynthesis, respiration, and combustion.
Conversely, large storms depress stream respiration over timescales of one month in streams with close coupling between gross primary productivity and respiration but over 1-2 day timescales in streams where these processes remain uncoupled.
