Approximate solution for solving nonlinear fractional order smoking model

open access: yesAlexandria Engineering Journal, 2020
In this paper, Generalized Mittag-Leffler function method (GMLFM) and Sumudu transform method (STM) are applied to study and solve the fractional order smoking model, where the derivatives are defined in the Caputo fractional sense.

Approximation by planar elastic curves [PDF]

open access: yes, 2016
We give an algorithm for approximating a given plane curve segment by a planar elastic curve. The method depends on an analytic representation of the space of elastic curve segments, together with a geometric method for obtaining a good initial guess for

Discrete quadratic splines

open access: yesInternational Journal of Mathematics and Mathematical Sciences, Volume 13, Issue 2, Page 343-348, 1990., 1990
In the present paper, we define a new class of discrete splines and study the existence, uniqueness, and convergence properties of discrete quadratic splines satisfying the Mean Averaging Condition.

Convexity preserving interpolation by splines of arbitrary degree [PDF]

open access: yesComputer Science Journal of Moldova, 2010
In the present paper an algorithm of $C^{2}$ interpolation of discrete set of data is given using splines of arbitrary degree, which preserves the convexity of given set of data.

Univariate approximating schemes and their non-tensor product generalization

open access: yesOpen Mathematics, 2018
This article deals with univariate binary approximating subdivision schemes and their generalization to non-tensor product bivariate subdivision schemes. The two algorithms are presented with one tension and two integer parameters which generate families

Bivariate Hermite subdivision [PDF]

open access: yes, 1996
A subdivision scheme for constructing smooth surfaces interpolating scattered data in $\mathbb{R}^3$ is proposed. It is also possible to impose derivative constraints in these points.

Hierarchical Riesz bases for Hs(Omega), 1 < s < 5/2 [PDF]

open access: yes, 2005
On arbitrary polygonal domains $Omega subset RR^2$, we construct $C^1$ hierarchical Riesz bases for Sobolev spaces $H^s(Omega)$. In contrast to an earlier construction by Dahmen, Oswald, and Shi (1994), our bases will be of Lagrange instead of Hermite ...

Wendland functions with increasing smoothness converge to a Gaussian

open access: yes, 2013
The Wendland functions are a class of compactly supported radial basis functions with a user-specified smoothness parameter. We prove that with a linear change of variables, both the original and the "missing" Wendland functions converge uniformly to a ...

A quadrature formula associated with a univariate quadratic spline quasi-interpolant [PDF]

open access: yes, 2007
International audienceWe study a new simple quadrature rule based on integrating a $C^1$ quadratic spline quasi-interpolant on a bounded interval. We give nodes and weights for uniform and non-uniform partitions.
