A computational scheme to model the geoid by the modified Stokes formula without gravity reductions

open access: yesJournal of Geodesy, 2003
In a modern application of Stokes' formula for geoid determination, regional terrestrial gravity is combined with long-wavelength gravity information supplied by an Earth gravity model.

Computational formula of depth for Catmull–Clark subdivision surfaces

open access: yesJournal of Computational and Applied Mathematics, 2006
In this paper, by introducing the concept of neighbor points and using the first-order difference of control points of Catmull-Clark surfaces, we obtain the rate of convergence of control meshes of Catmull-Clark surface.

Formulas for threshold computations

Computers and Biomedical Research, 1991
Given a continuous variable S, which density functions on two subgroups omega + and omega - of a population omega are known (with for instance a higher mean value on omega + than on omega -), we first define two strategies for classification in these groups; the first one (MWC) consists in determining a threshold alpha such that classifying in omega ...
