On Depth Recovery from Gradient Vector Fields

Depth recovery from gradient vector fields is required when reconstructing a surface (in three-dimensional space) from its gradients. Such a reconstruction task results, for example, for techniques in computer vision aiming at calculating surface normals (such as shape from shading, photometric stereo, shape from texture, shape from contours and so on). Surprisingly, discrete integration has no...

Oil displacement through a porous medium with a temperature gradient.

We investigate the effect of a temperature gradient on oil recovery in a two-dimensional pore-network model. The oil viscosity depends on temperature as μ(o) [Please see text] e(B/T), where B is a physicochemical parameter, depending on the type of oil, and T is the temperature. A temperature gradient is applied across the medium in the flow direction. Initially, the porous medium is saturated ...

Effects of Vertical Temperature Gradient on Heavy Gas Dispersion in Build up Area

ewline"> Dispersion of heavy gases is considered to be more hazardous than the passive ones because it takes place more slowly. ...

Numerical and Experimental Study of Effect of Scan Velocity in Laser Forming by Temperature Gradient Mechanism

In this paper the process of laser forming has been investigated using an analytical and an experimental method for three levels scans velocity. A coupled analysis has been performed in ANSYS®. Also in order to prove the predictive methods, experiments on thin sheet metals have been done when a laser of a fair power was used. Before done, experiments were designed with full factorial chosen as ...
