Piecewise rational rotation-minimizing motions via data stream interpolation
Carlotta Giannelli, Lorenzo Sacco, Alessandra Sestini +1
When a moving frame defined along a space curve is required to keep an axis aligned with the tangent direction of motion, the use of rotation-minimizing frames (RMF) avoids unneces…
A positive meshless finite difference scheme for scalar conservation laws with adaptive artificial viscosity driven by fault detection
Cesare Bracco, Oleg Davydov, Carlotta Giannelli +1
We present a meshless finite difference method for multivariate scalar conservation laws that generates positive schemes satisfying a local maximum principle on irregular nodes and…
Robust path following for autonomous vehicles with spatial PH quintic splines
Vincenzo Calabrò, Carlotta Giannelli, Lorenzo Sacco +1
The distinctive feature of a polynomial parametric speed let polynomial Pythagorean-hodograph (PH) curves be attractive for the design of accurate and efficient application algorit…
Local spline refinement driven by fault jump estimates for scattered data approximation
Cesare Bracco, Carlotta Giannelli, Francesco Patrizi +1
We present new fault jump estimates to guide local refinement in surface approximation schemes with adaptive spline constructions. The proposed approach is based on the idea that,…
