On Surface Approximation Using Developable Surfaces

Graphical Models and Image Processing, 1999
Summary: The author introduce a method for approximating a given surface by a developable surface. It will be either a \(G^1\) surface consisting of pieces of cones or cylinders of revolution or a \(G^r\) NURBS developable surface. This algorithm also deals properly with the problems of reverse engineering and produce robust approximation of given ...

Surface forces and surface interactions

Journal of Colloid and Interface Science, 1977
Abstract This paper discusses briefly some of the theoretical problems relating to surface problems as seen by an experimental physicist. In particular, questions are raised concerning the calculation of interaction energies between condensed phases in atomic contact.

Surface alloys, surface rumpling and surface stress

Surface Science, 2004
Abstract The results of density functional theory calculations of the surface structure and surface stress of a series of 13 different surface alloy phases for which there are quantitative experimental structure determinations are presented, 12 involving alloying adsorbate atoms (Au, Pd, Bi, Sn, Mg, Pb) with larger atomic radii than those of the ...

Surface and normal ensembles for surface reconstruction

Computer-Aided Design, 2007
The majority of the existing techniques for surface reconstruction and the closely related problem of normal reconstruction are deterministic. Their main advantages are the speed and, given a reasonably good initial input, the high quality of the reconstructed surfaces.

Surfaces and surface metrology

International Journal of Precision Technology, 2013
This paper discusses manufacturing methods for surfaces of simple to freeform geometry and the need to control the form and surface topography. Measurement techniques for assessment of form error and surface topography are outlined. At the end, engineered surfaces are taken and examined in the same context.

Identity Surfaces

Zeitschrift für Analysis und ihre Anwendungen, 2000
It is well-known that the zeros of holomorphic functions in more than one complex variable are not isolated. Nevertheless, there exist so-called identity surfaces such that a holomorphic function vanishes identically everywhere if only it equals zero on an identity surface.

Surface-surface phonon scattering by surface inhomogeneities

Journal of Physics: Condensed Matter, 1992
A one-dimensional model is presented for surface phonon scattering into surface phonon channels by atomic inhomogeneities along a high symmetry direction in a solid surface. The model yields characteristic resonances over the full Brillouin zone of the model linear chain, for a monoatomic step and an adatom, at the limit of low concentrations where the
