Special Splines of Exponential Type for the Solutions of Mass Transfer Problems in Multilayer Domains

open access: yesMathematical Modelling and Analysis, 2016
We consider averaging methods for solving the 3-D boundary-value problem of second order in multilayer domain. The special hyperbolic and exponential type splines, with middle integral values of piece-wise smooth function interpolation are considered ...

A generalized form of the parametric spline methods of degree (2k + 1) for solving a variety of two-point boundary value problems [PDF]

open access: yesIranian Journal of Numerical Analysis and Optimization, 2023
In this paper, a high order accuracy method is developed for finding the approximate solution of two-point boundary value problems. The present approach is based on a special algorithm, taken from Pascal’s triangle, for obtaining a generalized form of ...

Error analysis for a special X-spline [PDF]

open access: yesComputing, 1980
Clenshaw and Negus [1] defined the cubic X-spline, and they applied it to an interpolation problem. In the present paper, for the same interpolation problem, an interpolating splinew is considered by combining two specialX-splines. The construction ofw is such that the computational labour for its determination, in the case of piecewise equally spaced ...

Generalized de Boor–Cox Formulas and Pyramids for Multi-Degree Spline Basis Functions

open access: yesMathematics, 2023
The conventional B-splines possess the de Boor–Cox formula, which relates to a pyramid algorithm. However, for multi-degree splines, a de Boor–Cox-type evaluation algorithm only exists in some special cases.

Approximation and geometric modeling with simplex B-splines associated with irregular triangles [PDF]

open access: yes, 1990
Bivariate quadratic simplical B-splines defined by their corresponding set of knots derived from a (suboptimal) constrained Delaunay triangulation of the domain are employed to obtain a C1-smooth surface.
