Mathematical Relationship Between Particle Reynolds Number and Ripple Factor using Tapi River Data, India. [PDF]

Journal of Systemics, Cybernetics and Informatics, 2011
The computation of bed load allows for the fact that only part of the shear stress is used for transport of sediments and some of the shear stress is wasted in overcoming the resistance due to bed forms therefore the total shear stress developed in the ...

Unitarity constraints on the ratio of shear viscosity to entropy density in higher derivative gravity [PDF]

, 2010
We discuss corrections to the ratio of shear viscosity to entropy density $\eta/s$ in higher-derivative gravity theories. Generically, these theories contain ghost modes with Planck-scale masses.
