In the currently existing physical models of wetting a solid substrate by liquid drop, contact angle is determined on basis equilibrium forces acting tangentially to wetted surface at any point in perimeter area, ignoring (or their components) perpendicular this area. solution shown paper, state droplet was based minimum mechanical energy that achieves equilibrium. This approach allows one take...

We introduce a new surface representation for recognizing curved objects. Our approach begins by representing an object by a discrete mesh of points built from range data or from a geometric model of the object. The mesh is computed from the data by deforming a standard shaped mesh, for example, an ellipsoid, until it fits the surface of the object. We define local regularity constraints that t...

In recent years, the Indian Ocean (IO) has been discovered to have a much larger impact on climate variability than previously thought. This paper reviews processes in which the IO is, or appears to be, actively involved. We begin the mathematical model with a pattern for summer monsoon winds. Three dimensional temperature and velocity fields are calculated analytically for the ocean forced by ...

The prediction of cross sections for nuclei far off stability is crucial in the field of nuclear astrophysics. For spherical nuclei close to the dripline the statistical model (Hauser-Feshbach) approach is not applicable and direct contributions may dominate the cross sections. For neutron-rich, even-even Sn targets, we compare the resulting neutron capture cross sections when consistently taki...

Most studies of surface color appearance have ignored 3-D illumination phenomena such as shadows and interreflections. These phenomena must affect surface color appearance to some extent, but without a model we cannot make claims about how great these effects really are. In this article, we introduce a simple model of how interreflections can affect color appearance. We consider a family of ide...
