The EH Interpolation Spline and Its Approximation
Abstract and Applied Analysis, 2014 A new interpolation spline with two parameters, called EH interpolation spline, is presented in this paper, which is the extension of the standard cubic Hermite interpolation spline, and inherits the same properties of the standard cubic Hermite ...

Volume reconstruction based on the six-direction cubic box-spline
Graphical Models, 2023 We propose a new volume reconstruction technique based on the six-direction cubic box-spline M6. M6 is C1 continuous and possesses an approximation order of three, the same as that of the tri-quadratic B-spline but with much lower degree. In fact, M6 has

Multidimensional Additive Spline Approximation [PDF]
SIAM Journal on Scientific and Statistical Computing, 1983 We describe an adaptive procedure that approximates a function of many variables by a sum of (univariate) spline functions $s_m $ of selected linear combinations $a_m \cdot x$ of the coordinates \[ \phi (x) = \sum_{1 \leqq m \leqq M} {s_m ( a_m \cdot x)}.

Neutrosophication of Neutrosophic B-Spline Curve Approximation Model [PDF]
Neutrosophic Sets and SystemsThe neutrosophication process involves transforming crisp input value into neutrosophic value. It is a primary and crucial step for the operations within a neutrosophic set and system.

On smoothing problems with one additional equality condition
Mathematical Modelling and Analysis, 2009 Two problems of approximation in Hilbert spaces are considered with one additional equality condition: the smoothing problem with a weight and the smoothing problem with an obstacle.

Approximation of splines in Wasserstein spaces
ESAIM: Control, Optimisation and Calculus of VariationsThis paper investigates a time discrete variational model for splines in Wasserstein spaces to interpolate probability measures. Cubic splines in Euclidean space are known to minimize the integrated squared acceleration subject to a set of interpolation constraints.

B-spline neural network based single-carrier frequency domain equalisation for Hammerstein channels [PDF]
, 2014 A practical single-carrier (SC) block transmission with frequency domain equalisation (FDE) system can generally be modelled by the Hammerstein system that includes the nonlinear distortion effects of the high power amplifier (HPA) at transmitter.

The degree of approximation by Chebyshevian splines [PDF]
Transactions of the American Mathematical Society, 1973 This paper studies the connections between the smoothness of a function and its degree of approximation by Chebyshevian splines. This is accomplished by proving companion direct and inverse theorems which give a characterization of smoothness in terms of degree of approximation. A determination of the saturation properties is included.

On Convex Approximation by Quadratic Splines
Journal of Approximation Theory, 1996 This note is devoted to giving a short and constructive proof for the existence of a \(C^1\) convex quadratic spline with \(n\) equidistant knots which approximates a convex function \(f\in C[0,1]\) at the order \(\omega_3(f,1/n)\). This improves a result due to \textit{Y. K. Hu} [J. Approximation Theory 74, No.
