Computation of transient viscous flows using indirect radial basis function networks [PDF]

open access: yes, 2007
In this paper, an indirect/integrated radial-basis-function network (IRBFN) method is further developed to solve transient partial differential equations (PDEs) governing fluid flow problems.

Application of C-Bézier and H-Bézier basis functions to numerical solution of convection-diffusion equations

open access: yesBoundary Value Problems, 2022
Convection-diffusion equation is widely used to describe many engineering and physical problems. The finite element method is one of the most common tools for computing numerical solution. In 2003, Wang et al.

Laplacian spectral basis functions [PDF]

open access: yesComputer Aided Geometric Design, 2018
Representing a signal as a linear combination of a set of basis functions is central in a wide range of applications, such as approximation, de-noising, compression, shape correspondence and comparison. In this context, our paper addresses the main aspects of signal approximation, such as the definition, computation, and comparison of basis functions ...

Numerical Study on an RBF-FD Tangent Plane Based Method for Convection–Diffusion Equations on Anisotropic Evolving Surfaces

open access: yesEntropy, 2022
In this paper, we present a fully Lagrangian method based on the radial basis function (RBF) finite difference (FD) method for solving convection–diffusion partial differential equations (PDEs) on evolving surfaces.

PARAMETRIC IDENTIFICATION OF THE INCIDENT HEAT FLOW AS A FUNCTION OF TIME AND COORDINATES BY ITERATIVE REGULARIZATION

open access: yesНадежность и качество сложных систем, 2022
Background. The method of restoring the incident heat flow as a function of time is considered on the example of a virtual model of a parallelepiped. The purpose of this method is to find the global minimum of the parametric value of the heat flow from

On Homomorphisms from Cn to Cm

open access: yesRatio Mathematica, 2020
In this paper, using elementary algebra and analysis, we characterize and compute all continuous homomorphism from Cn to Cm. Also we prove that the cardinality of the set of all non-continous group homomorphism from Cn to Cm is at least the cardinality ...

Electronic stress tensor of the hydrogen molecular ion: Comparison between the exact wave function and approximate wave functions using Gaussian basis sets [PDF]

open access: yes, 2010
We investigate the electronic stress tensor of the hydrogen molecular ion for the ground state using the exact wave function and wave functions approximated by gaussian function basis set expansion.

Selection of Wavelet Basis Function for Image Compression – A Review

open access: yesELCVIA Electronic Letters on Computer Vision and Image Analysis, 2019
Wavelets are being suggested as a platform for various tasks in image processing. The advantage of wavelets lie in its time frequency resolution. The use of different basis functions in the form of different wavelets made the wavelet analysis as a ...
