An exponential spline approximation for fractional Bagley–Torvik equation
Boundary Value Problems, 2020 In this paper, we approximate the solution of fractional Bagley–Torvik equation by using the exponential spline function and the shifted Grünwald difference operator. The proposed methods reduce to the system of algebraic equations.

Hierarchical Spline Approximation
, 2001 We discuss spline refinement methods that approximate multi-valued data defined over one, two, and three dimensions. The input to our method is a coarse decomposition of the compact domain of the function to be approximated consisting of intervals (univariate case), triangles (bivariate case), and tetrahedra (trivariate case).

Journal of Engineering, 2013 In this work we introduce a new family of splines termed as gamma splines for continuous signal approximation and multiresolution analysis. The gamma splines are born by -times convolution of the exponential by itself.

Convex Approximation by Quadratic Splines
Journal of Approximation Theory, 1993 The author estimates the error of approximation by \(C^ 1\)-convex quadratic splines of a given convex function \(f\) without any smoothness requirements on its derivative in terms of \(\omega_ 3(f,{1 \over n})\). Actually, he proves the following main Theorem: Let \(f \in C[0,1]\) be a convex, and \(n\) a positive integer.

Images denoising in case impulse noise using spline approximation
MATEC Web of Conferences, 2018 Analytical equations of a new spline approximation method for filtering impulse noise in images are obtained. The proposed method differs from the known ones: when filtering images, one-dimensional sequential spline functions are used for direct and ...

, 2019 Dissertatsioonis on käsitletud kolme probleemi splainide teooriast. Esiteks vaadeldakse kuupsplainidega histopoleerimist. Antud on suvaliselt paiknevate sõlmedega ja suvaliste kõrgustega histogramm. Näidatakse, et alati on olemas histopoleeriv kuupsplain üldka-su¬tatavate rajatingimuste korral. Splaini leidmisel kasutatakse erinevaid esitusi.
