On Shifted Cardinal Interpolation by Gaussians and Multiquadrics

open access: yesJournal of Approximation Theory, 1996
The authors study so-called shifted Gaussian interpolation where approximants are given as a (finite or infinite) linear combination of translates of some Gaussian. More precisely, the approximants \(s\) are of the form \[ s(x)= \sum_{k\in\mathbb{Z}^d} a_k \varphi(x+\alpha-k) \qquad (x\in\mathbb{R}^d), \tag{1} \] where \(\mathbb{Z}\) is the set of ...

Radial basis functions-finite differences collocation and a Unified Formulation for bending, vibration and buckling analysis of laminated plates, according to Murakami's zig-zag theory [PDF]

open access: yes, 2011
In this paper, we propose to use the Murakami's zig-zag theory for the static and vibration analysis of laminated plates, by local collocation with radial basis functions in a finite differences framework.

Regular Families of Kernels for Nonlinear Approximation

open access: yes, 2019
This article studies sufficient conditions on families of approximating kernels which provide $N$--term approximation errors from an associated nonlinear approximation space which match the best known orders of $N$--term wavelet expansion.

Explicit Runge-Kutta Methods with Multiquadric and Inverse Multiquadric Radial Basis Functions

open access: yesInternational Journal of Computational Methods
In this article, a family of two- and three-stage explicit multiquadric (MQ) and inverse multiquadric (IMQ) radial basis functions (RBFs) Runge-Kutta methods are introduced for solving ordinary differential equations. These methods are developed by utilizing MQ- and IMQ-RBF Euler methods.
