UTD computation for NURBS surfaces
, 2022 S.669-672One of the main problems in computing the UTD surface diffracted fields on surfaces described by Non-Uniform Rational B-splines (NURBS) is due to the difficulty in determining the geodesic paths the electromagnetic waves takes along the surface.

A New Path Generation Algorithm Based on Accurate NURBS Curves
International Journal of Advanced Robotic Systems, 2016 The process of finding an optimum, smooth and feasible global path for mobile robot navigation usually involves determining the shortest polyline path, which will be subsequently smoothed to satisfy the requirements. Within this context, this paper deals
