Linear minimum-variance approximants for noisy data
Sergio López Ureña, Dionisio F. Yáñez
Inspired by recent developments in subdivision schemes founded on the Weighted Least Squares technique, we construct linear approximants for noisy data in which the weighting strat…

A Multiresolution approach to solve large-scale optimization problems
Rosa Donat, Sergio López Ureña
General purpose optimization techniques can be used to solve many problems in engineering computations, although their cost is often prohibitive when the number of degrees of freed…

Nonlinear stationary subdivision schemes that reproduce trigonometric functions
Rosa Donat, Sergio López-Ureña
In this paper we define a family of nonlinear, stationary, interpolatory subdivision schemes with the capability of reproducing conic shapes including polynomials upto second order…
