Mixing efficiency in natural flows [PDF]
Philosophical Transactions Series A, Mathematical, Physical, and Engineering Sciences, 2013 Abstract It is argued that the mixing efficiency of naturally occurring stratified shear flows, γ=Rf/(1−Rf), where Rf is the flux Richardson number, is dependent on at least two governing parameters: the gradient Richardson number Ri and the buoyancy Reynolds number Reb=ε/vN2.

An efficient mixed attention module
IET Computer Vision, 2023 Abstract Recently, the application of attention mechanisms in convolutional neural networks (CNNs) has become a hot area in computer vision. Most existing methods focus on channel attention or spatial attention. Some mixed attention usually achieves better performance than channel attention or spatial attention with the help of a ...
