gradient flow

gradient flow

[′grād·ē·ənt ‚flō]
(meteorology)
Horizontal frictionless flow in which isobars and streamlines coincide, or equivalently, in which the tangential acceleration is everywhere zero; the balance of normal forces (pressure force, Coriolis force, centrifugal force) is then given by the gradient wind equation.

If both layers use miscible solvents, diffusion may lead to nonuniform liquid composition along the top surface and consequently surface tension gradient flow. This Marangoni flow ultimately may lead to dewetting of the top layer, even for cases at which the surface tension of the top layer is lower than that of the bottom layer.
All these monitoring stations together will help to compute the gradient flow of glacier mass, surface velocity and the rate at which glacier accumulates and loses its mass.
Important open problems are stated, proposing the study of PDE metric flow in the direction of Hessian, of PDE metric dynamics in the direction of Hessian and of minus gradient flow ODE.
Secondly, consider the case that h is a gradient flow, i.e., there exists a smooth, real=valued function H on M such that h = - grad H.
Multi-dimensional separations are simplified by enabling columns that differ in chemistry and internal diameter to be combined on a single LC system with dual gradient flow delivery and a proprietary flow path design.
It consists on the utilization of user-initialized curves that "evolve" inside the image until they find the contour sought for, taking advantages of different possible mechanisms, as B-splines, vector gradient flow and others.
It provides a gradient flow range of 50 nl/min to 25 [micro]l min for use with 50 [micro] to 300 [micro] ID columns.
