In this paper,a new method for approximation of conic section by quartic Bézier curve is presented,based on the quartic Bézier approximation of circular arcs.
Bent functions are maximally nonlinear Boolean functions with an even number of variables.Not only for their own sake as interesting combinatorial objects,b
In this paper,we propose a novel unsupervised algorithm for automatically segmenting a 3D shape or co-segmenting a set of 3D shapes of the same family by using
Generalized B-splines in non-polynomial space has been employed as analysis tools for IGA.However,the previous models used in IGA are not the unified mathematic
In isogeometric analysis(IGA),parametrization is a challenging work that greatly influences the numerical accuracy and efficiency of the numerical solution.
