This paper considers the interpretation (as a three-dimensional velocity field) of the changing intensity pattern induced by a smoothly deforming Lambertian surface of uniform albedo illuminated by a distant point light source. The requisite "Intensity Rate Constraint" which is derived contains no terms relating to the tangential components of surface velocity, so the determination of the veloc...

-The phase distribution nonuniformities near bounding surfaces result in anisotropy and nonuniformity of the effective thermal conductivity tensor. For a two-dimensional porous medium made of cylindrical particles, we evaluate the properties of this tensor for cases where the medium is bounded by the fluid saturating it or by a solid surface. The use of a uniform effective conductivity, such as...

Biirger, H. and R. Schaback, A parallel multistage method for surface/surface intersection, Computer Aided Geometric Design 10 (1993) 277-291. A global divide-and-conquer method and a local marching method are combined into a massively parallel algorithm for surface/surface intersection. Special attention is given to the comparison of bounding boxes and to the safe and efficient calculation of ...
