In the case of a well in a leaky aquifer, the criterion for critical damping is a simple power expression that relates the leakage factor and the storativity of the aquifer and where the exponent is a function of the transmissivity of the aquifer. If the damping is critical and the ...

Josephson current is investigated in the superconductor/ferromagnet/superconductor junction. It was shown that the current exhibited damping oscillations as a function of the ferromagnetic layer thickness. Previous theories based on Usadel or Eilenberger equations have predicted that the damping length and...
Critical altitude itself is a function of density altitude, so the height at which you can maintain climb power will be lower on a hot day. High and hot how-to: use these tips to reliably go beyond the book and ensure adequate performance in high-density-altitude operations More results ...
An interface model is often extended from the model of fundamental soils by considering a suitable interface thickness, which is a function of the particle size, angularity, surface roughness, particle hardness, and net normal stress. Then, the relation between stress–strain-displacement is applied...

However, in the open literature, very little is said about the fate of nAl particles passing through the throat area of the gasdynamic expansion nozzle. In addition, with respect to the conventional μAl particles, nAl is appreciably less effective in damping out SRM acoustic instability [29] ...
