Exponential Splines of Complex Order

, 2013
We extend the concept of exponential B-spline to complex orders. This extension contains as special cases the class of exponential splines and also the class of polynomial B-splines of complex order.

Towards a More General Type of Univariate Constrained Interpolation With Fractal Splines

, 2015
Recently, in [Electronic Transaction on Numerical Analysis, 41 (2014), pp. 420-442] authors introduced a new class of rational cubic fractal interpolation functions with linear denominators via fractal perturbation of traditional nonrecursive rational ...

Linear dependence of bivariate Minimal Support and Locally Refined B-splines over LR-meshes [PDF]

, 2019
The focus on locally refined spline spaces has grown rapidly in recent years due to the need in Isogeoemtric analysis (IgA) of spline spaces with local adaptivity: a property not offered by the strict regular structure of tensor product B-spline spaces ...

B-spline curve theory: An overview and applications in real life

Nonlinear Engineering
This study commences by delving into B-spline curves, their essential properties, and their practical implementations in the real world. It also examines the role of knot vectors, control points, and de Boor’s algorithm in creating an elegant and ...

Shape preserving $C^2$ interpolatory subdivision schemes [PDF]

, 1998
Stationary interpolatory subdivision schemes which preserve shape properties such as convexity or monotonicity are constructed. The schemes are rational in the data and generate limit functions that are at least $C^2$.

Local interpolation schemes for landmark-based image registration: a comparison

, 2014
In this paper we focus, from a mathematical point of view, on properties and performances of some local interpolation schemes for landmark-based image registration.

O modelo logspline aplicado aos transectos lineares. [PDF]

, 2005
A teoria denominada logspline density estimation, permite estimar o logaritmo de uma função densidade de probabilidade utilizando-se splines cúbicos, estima ção por máxima verosimilhança, e adição e remoção de nós seleccionados pelas estatísticas de Rao ...

A quadrature formula associated with a univariate quadratic spline quasi-interpolant

, 2007
International audienceWe study a new simple quadrature rule based on integrating a $C^1$ quadratic spline quasi-interpolant on a bounded interval. We give nodes and weights for uniform and non-uniform partitions.

Splines in Numerical Integration [PDF]

, 2010
AMS Subj. Classification: 65D07, 65D30.We gave a short review of several results which are related to the role of splines (cardinal, centered or interpolating) in numerical integration.
