Convergence Analysis of Cubic Spline Function with Fractional Degree and Applications [PDF]
مجلة جامعة الانبار للعلوم الصرفة, 2023 In this paper, a fractional degree cubic spline scheme is proposed and analyzed for fractional order with the multi-term Riemann–Liouvile (R–L) derivatives. For the integral and fractional differential equations, we handle fractional continuity equations

Smoothing data series by means of cubic splines: quality of approximation and introduction of a repeating spline approach [PDF]
Atmospheric Measurement Techniques, 2017 Cubic splines with equidistant spline sampling points are a common method in atmospheric science, used for the approximation of background conditions by means of filtering superimposed fluctuations from a data series.

Bivariate segment approximation and splines [PDF]
Advances in Computational Mathematics, 1996 The problem to determine partitions of a given rectangle which are optimal for segment approximation (e.g., by bivariate piecewise polynomials) is investigated. We give criteria for optimal partitions and develop algorithms for computing optimal partitions of certain types.

Mathematics, 2019 The B-spline function representation is commonly used for data approximation and trajectory definition, but filter-based methods for nonlinear weighted least squares (NWLS) approximation are restricted to a bounded definition range.

Optimal Approximation of Biquartic Polynomials by Bicubic Splines
EPJ Web of Conferences, 2018 Recently an unexpected approximation property between polynomials of degree three and four was revealed within the framework of two-part approximation models in 2-norm, Chebyshev norm and Holladay seminorm.

Neutrosophic B-spline Surface Approximation Model for 3-Dimensional Data Collection [PDF]
Neutrosophic Sets and SystemsSince there are threei membershipi functions: truth, false, and indeterminacyi, geometrical modelingi for B-spline surface approximation including neutrosophic data is particularly difficult to construct.

New Cubic B-Spline Approximation for Solving Linear Two-Point Boundary-Value Problems
Mathematics, 2021 In this study, we introduce a new cubic B-spline (CBS) approximation method to solve linear two-point boundary value problems (BVPs). This method is based on cubic B-spline basis functions with a new approximation for the second-order derivative.

Contour Detection of Mammogram Masses Using ChanVese Model and B-Spline Approximation
International Journal of Interactive Multimedia and Artificial Intelligence, 2017 ChanVese model segmentation has been applied for contour detection of mass region in mammogram in our previous work. Available information of the desired object contour is used, in this paper, for B-spline approximation. The mass region boundary (contour)

Journal of Approximation Theory, 2003 Uniqueness and approximation orders of perfect splines are studied in this article. In the main result, upper bounds to the best approximation by perfect splines to continuous functions are provided. Moreover, the approximation results are related to the so-called \(\Sigma\Delta\) modulation of bandlimited univariate signals.
