On nonparametric estimating ROC curve based on non-uniform rational B-spline. [PDF]
PLoS OneThe receiver operating characteristic (ROC) curve is a commonly used statistical method to assess the efficacy of a diagnostic test or biomarker measured on a continuous scale. This work presents a versatile approach using a non-uniform rational B-spline (NURBS) for estimating the ROC curve.

Discretization of Non-uniform Rational B-Spline (NURBS) Models for Meshless Isogeometric Analysis. [PDF]
J Sci ComputAbstractWe present an algorithm for fast generation of quasi-uniform and variable-spacing nodes on domains whose boundaries are represented as computer-aided design (CAD) models, more specifically non-uniform rational B-splines (NURBS). This new algorithm enables the solution of partial differential equations within the volumes enclosed by these CAD ...
