Surface grid generation for complex three-dimensional geometries [PDF]
An outline is presented for the creation of surface grids from primitive geometry data such as obtained from CAD/CAM systems. The general procedure is applicable to any geometry including full aircraft with wing, nacelle, and empennage. When developed in

Recognition of 3-D symmetric objects from range images in automated assembly tasks [PDF]
A new technique is presented for the three dimensional recognition of symmetric objects from range images. Beginning from the implicit representation of quadrics, a set of ten coefficients is determined for symmetric objects like spheres, cones ...

Model-Invariant Hybrid RANS-LES Computations on Unstructured Meshes [PDF]
Hybrid RANS-LES computations combine the bene ts of RANS and LES so that LES is used in regions where the accuracy of RANS deteriorates. The numerous hybrid approaches are limited by the speci cation of the LES-RANS interface, which can cause nonphysical

Derivation of transformation formulas between geocentric and geodetic coordinates for nonzero altitudes [PDF]
Four formulas, for the nonzero altitude transformation from geodetic coordinates (geodetic latitude and altitude) to geocentric coordinates (geocentric latitude and geocentric distance) and vice versa, are derived.

Some properties of n-dimensional triangulations [PDF]
A number of mathematical results relevant to the problem of constructing a triangulation, i.e., a simplicial tessellation, of the convex hull of an arbitrary finite set of points in n-space are described.
