Moving contact line with balanced stress singularities
A difficulty in the classical hydrodynamic analysis of moving contact-line problems, associated with the no-slip wall boundary condition resulting in an unbalanced divergence of the viscous stresses, is reexamined with a smoothed, finite-width interface model. The analysis in the sharp-interface limit shows that the singularity of the viscous stress can be balanced by another singularity of the...
متن کاملLine Bundles Associated with Normal Surface Singularities
In [15] L. Nicolaescu and the author formulated a conjecture which relates the geometric genus of a complex analytic normal surface singularity (X, 0) (whose link M is a rational homology sphere) with the Seiberg-Witten invariant of M associated with the “canonical” spin structure of M . (The interested reader is invited to see the articles [15, 16, 17, 13, 19, 20] for the verification of the c...
متن کاملA Fast Algorithm for Line Clipping by Convex Polyhedron in E3
A new algorithm for line clipping against convex polyhedron is given. The suggested algorithm is faster for higher number of facets of the given polyhedron than the traditional Cyrus-Beck's and others algorithms with complexity O N ( ) . The suggested algorithm has O N ( ) complexity in the worst case and expected O N ( ) complexity. The speed up is achieved because of "known order" of triangle...
متن کاملComputing a Attest, Undercut{free Parting Line for a Convex Polyhedron, with Application to Mold Design ?
A parting line for a convex polyhedron, P, is a closed curve on the surface of P. It deenes the two pieces of P for which mold-halves must be made. An undercut-free parting line is one which does not create recesses or projections in P and thus allows easy de-molding of P. Computing an undercut-free parting line that is as at as possible is an important problem in mold design. In this paper, an...
متن کاملComputing a Flattest, Undercut-Free Parting Line for a Convex Polyhedron, with Application to Mold Design
A parting line for a polyhedron is a closed curve on its surface, which identiies the two halves of the polyhedron for which mold-boxes must be made. A parting line is undercut-free if the two halves that it generates do not contain facets that obstruct the de-molding of the polyhedron. Computing an undercut-free parting line that is as \\at" as possible is an important problem in mold design. ...
