Convergence of Integro Quartic and Sextic B-Spline interpolation [PDF]
Sahand Communications in Mathematical Analysis, 2018 In this paper, quadratic and sextic B-splines are used to construct an approximating function based on the integral values instead of the function values at the knots.

Journal of Computational and Applied Mathematics, 1994 The main subject of this paper is the convolution of spline functions. In particular, the author gives an expression for the convolution of a spline over nonuniform knots with \(B\)-splines as a linear combination of \(B\)-splines of higher order. The coefficients are expressed in terms of divided differences and can be evaluated by a stable recurrence

A quadratic trigonometric B-Spline as an alternate to cubic B-spline
Alexandria Engineering Journal, 2022 The idea of the quadratic trigonometric spline (QTS) for the curve modeling approach inspired this paper using a quadratic trigonometric function presented in it. By creating B-spline-like local support basis functions, a competent freeform curve design approach is created.

Hermite B-Splines: n-Refinability and Mask Factorization
Mathematics, 2021 This paper deals with polynomial Hermite splines. In the first part, we provide a simple and fast procedure to compute the refinement mask of the Hermite B-splines of any order and in the case of a general scaling factor.

Natural Frequencies of Levodopa‐Induced Dyskinesia in Parkinson's Disease
Annals of Clinical and Translational Neurology, EarlyView.ABSTRACT Objectives Abnormal involuntary movements, known as dyskinesias, are common complications of levodopa treatment in patients with Parkinson's disease and can significantly impair quality of life. The underlying pathophysiology remains unclear, and current therapeutic options are limited.

B‐splines image approximation using resampled chordal parameterization
IET Image ProcessingImage processing often requires filtering, which can be effectively performed by using B‐spline surface approximation. This article presents a fast method of approximating data in rectangular (image) form using such surfaces. The method considers dynamic
