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

A numerical approach for solving Fisher’s reaction–diffusion equation via a new kind of spline functions

Ain Shams Engineering Journal, 2021
The objective of this work is to propose a hybrid numerical method for the approximation of Fisher’s reaction–diffusion equation. The method is based on cubic uniform algebraic trigonometric (CUAT) tension B-spline functions and differential quadrature ...

Sampling and Reconstruction of Shapes with Algebraic Boundaries [PDF]

, 2015
We present a sampling theory for a class of binary images with finite rate of innovation (FRI). Every image in our model is the restriction of $\mathds{1}_{\{p\leq0\}}$ to the image plane, where $\mathds{1}$ denotes the indicator function and $p$ is some

An Upper Bound of the Bezout Number for Piecewise Algebraic Curves over a Rectangular Partition

International Journal of Mathematics and Mathematical Sciences, 2012
A piecewise algebraic curve is a curve defined by the zero set of a bivariate spline function. Given two bivariate spline spaces (Δ) over a domain D with a partition Δ, the Bezout number BN(m,r;n,t;Δ) is defined as the maximum finite number of the ...
