Space-time radial basis functions

Computers & Mathematics with Applications, 2002
Radial basis functions have turned out in practice to be extremely useful and interesting to analyse for theoretical study. They are approximations that treat all components of the underlying -- possibly high-dimensional -- space equal, and, while this is usually an additional advantage, it is not, when space-time is studied.

Approximation of Bivariate Functions by Generalized Wendland Radial Basis Functions

Mathematics
In this work, we deal with two approximation problems in a finite-dimensional generalized Wendland space of compactly supported radial basis functions. Namely, we present an interpolation method and a smoothing variational method in this space. Next, the

Image reconstruction from scattered Radon data by weighted positive definite kernel functions [PDF]

, 2018
We propose a novel kernel-based method for image reconstruction from scattered Radon data. To this end, we employ generalized Hermite–Birkhoff interpolation by positive definite kernel functions. For radial kernels, however, a straightforward application

Analysis of laminated doubly-curved shells by alayerwise theory and radial basis functions collocation, accounting for through-the-thickness deformations

, 2011
In this paper, the static and free vibration analysis of laminated shells is performed by radial basis functions collocation, according to a sinusoidal shear deformation theory (SSDT).

A mixed method for Dirichlet problems with radial basis functions

, 2013
We present a simple discretization by radial basis functions for the Poisson equation with Dirichlet boundary condition. A Lagrangian multiplier using piecewise polynomials is used to accommodate the boundary condition.

Honey Yield Forecast Using Radial Basis Functions [PDF]

, 2018
Honey yields are difficult to predict and have been usually associated with weather conditions. Although some specific meteorological variables have been associated with honey yields, the reported relationships concern a specific geographical region ...

Application of Radial Basis Functions for Height Datum Unification

Geosciences, 2018
Local gravity field modelling demands high-quality gravity data as well as an appropriate mathematical model. Particularly in coastal areas, there may be different types of gravity observations available, for instance, terrestrial, aerial, marine gravity,

Adopting the Multiresolution Wavelet Analysis in Radial Basis Functions to Solve the Perona-Malik Equation [PDF]

Journal of Sciences, Islamic Republic of Iran, 2018
Wavelets and radial basis functions (RBF) have ubiquitously proved very successful to solve different forms of partial differential equations (PDE) using shifted basis functions, and as with the other meshless methods, they have been extensively used in ...
