On Point Spread Function modelling: towards optimal interpolation [PDF]
, 2011 Point Spread Function (PSF) modeling is a central part of any astronomy data analysis relying on measuring the shapes of objects. It is especially crucial for weak gravitational lensing, in order to beat down systematics and allow one to reach the full ...

On the Asymptotics of Fekete-Type Points for Univariate Radial Basis Interpolation
Journal of Approximation Theory, 2002 Here the Fekete type points of an interpolation process are defined to be the set \(X_n= \{x_1,\dots,x_n\}\) of \(n+1\) points which maximize the the absolute value of the determinant of the associated interpolation matrix.

Meshless Radial Point Interpolation Method for Hyperelastic Materials
Kalpa Publications in Engineering, 2020 Hyperelastic materials are special types of material that tends to behavior elastically when they are subjected to very large strains. These materials show not only the nonlinear material behavior but also the large deformation and stress-strain relationship is derived from a strain energy density function.

On the Factors Affecting the Accuracy and Robustness of Smoothed-Radial Point Interpolation Method [PDF]
Advances in Applied Mathematics and Mechanics, 2016 AbstractIn order to overcome the possible singularity associated with the Point Interpolation Method (PIM), the Radial Point Interpolation Method (RPIM) was proposed by G. R. Liu. Radial basis functions (RBF) was used in RPIM as basis functions for interpolation. All these radial basis functions include shape parameters.
