Vorticity is a measure of rotation in the atmosphere, or “spin,” in the air. If the spin, as viewed from above, is counterclock-wise in the Northern Hemisphere, it is called a vorticity cyclonic and given a positive value. If the spin is clock-wise, it is called a vorticity anticyc...
Here we put forward an optical sensing technique to obtain a direct measurement of vorticity in fluids using Laguerre-Gauss (LG) beams, optical beams which show an azimuthal phase variation that is the origin of its characteristic non-zero orbital angular momentum. The key point is to make use...
A measure of the non-coaxiality involved in progressive deformation histories is proposed in the form of the kinematical vorticity number, W k. This number is a measure of the relative effects of rotation of material lines (relative to the instantaneous stretching axes) and of stretching of these...
Vorticity in structural geology is a measure of the angular momentum of fluid flow. A vorticity meter is the one that is used to measure vorticity. A...Become a member and unlock all Study Answers Start today. Try it now Create an account Ask a question Our experts can answer your to...

-2*x^2-2*y^2-2*z^2 which is negative and has problem under square root. Could you please tell what causes this problem. Thank you very much. I do not understand what you did ... if you want to define a measure for a matrix, you should define some norm on that ||A||, this...

The selection of this interval is complicated by the presence of multiple flow regions with varying velocities; in such a flow, the proper interval may be suitable for a slower flow but unable to accurately measure the faster flow region, or vice versa. This problem limited the velocities that...
A numerical scheme applicable to arbitrarily-structured C-grids is presented for the nonlinear shallow-water equations. By discretizing the vector-invariant form of the momentum equation, the relationship between the nonlinear Coriolis force and the potential vorticity flux can be used to guarantee that...
Since an FM transmission has the property of generating a constant amplitude output, we adjusted the output of the two transmitters to measure the same receiver output voltage, 1 volt in continuous current (VCC) for each channel. In this way, we were able to characterize the transition between...
