Equiareal parameterizations of NURBS surfaces
Graphical Models, 2014 The equiareality of NURBS surfaces greatly affects the results of visualization and tessellation applications, especially when dealing with extruding and intruding shapes. To improve the equiareality of given NURBS surfaces, an optimization algorithm using the Mobius transformations is presented in this paper.

Optimal Design of Grooved Cam Profile Using Non-uniform Rational B-splines
MATEC Web of Conferences, 2017 In order to reduce the fatigue damage in grooved cam mechanisms, grooved cam profile was reconstructed with non-uniform rational B-splines (NURBS). Considering joint friction, dynamic model of grooved cam mechanisms was established and the contact stress
