Mixing Efficiency in the Ocean

Annual Review of Marine Science, 2018
Mixing efficiency is the ratio of the net change in potential energy to the energy expended in producing the mixing. Parameterizations of efficiency and of related mixing coefficients are needed to estimate diapycnal diffusivity from measurements of the turbulent dissipation rate.

Efficient mixed Timoshenko–Mindlin shell elements

International Journal for Numerical Methods in Engineering, 2002
AbstractThe precise representation of rigid body motions in the displacement patterns of curved Timoshenko–Mindlin (TM) shell elements is considered. This consideration requires the development of the strain–displacement relationships of the TM shell theory with regard to their consistency with the rigid body motions.

Case-mix adjustment and efficiency measurement

Scandinavian Journal of Public Health, 2004
Aims: The importance of using valid case-mix systems in long-term care is addressed by comparing the predictive power of different case-mix models, and by applying them in the calculation of technical efficiency scores of care units. Methods: To construct different case-mix models a statistical clustering technique (Automatic Interaction Detection) was

EVALUATION OF DISTRIBUTIVE MIXING EFFICIENCY IN MIXING EQUIPMENT

Chemical Engineering Communications, 1995
A framework was developed to evaluate the distributive mixing efficiency during processing in a mixer. The dynamics of distributive mixing was studied numerically by means of tracking the evolution of particles originally gathered as clusters. The goodness of mixing was characterized in terms of length stretch, pairwise correlation function and volume ...

Efficient Parametric Mixing in CdSe

Applied Physics Letters, 1971
We have obtained the first phase-matched nonlinear interaction in CdSe and have observed a 35% conversion efficiency for mixing 10.6 μ with a pump at 1.833 μ to generate a signal at 2.2 μ. The mixing process phase matches at 77° to the optic axis and confirms the predicted phase-matching angle.

Mixing efficiency of SIS junctions

IEEE Transactions on Magnetics, 1983
To evaluate new SIS technologies as low noise mixers we have investigated theoretically the frequency down-conversion efficiency of SIS junctions with IV curves which closely resemble experimentally observed curves. Leakage current and IV curve "sharpness" of the current rise at eV = \Delta_{1} + \Delta_{2} are included as parameters. We have applied a

Heterodyne mixing efficiency for detector arrays

Applied Optics, 1987
Monostatic radar equations are reported for laser-transceiver sensors that employ coherent optical detection over a linear-array photodetector. Explicit results are presented illustrating the impact of transmitter and receiver antenna patterns on the heterodyne mixing efficiency achieved by each detector element.
