Adaptive meshless centres and RBF stencils for Poisson equation [PDF]

, 2011
We consider adaptive meshless discretisation of the Dirichlet problem for Poisson equation based on numerical differentiation stencils obtained with the help of radial basis functions. New meshless stencil selection and adaptive refinement algorithms are

Radial Basis Point Interpolation Method with Reordering Gauss Domains for 2D Plane Problems

Journal of Applied Mathematics, 2014
We present novel Gauss integration schemes with radial basis point interpolation method (RPIM). These techniques define new Gauss integration scheme, researching Gauss points (RGD), and reconstructing Gauss domain (RGD), respectively.

A modified radial basis function interpolation method for aerodynamic load application

Hangkong gongcheng jinzhan
Aerodynamic loads are an important type of load in finite element analysis of aircraft structures. Due to the mismatch between the mesh used in computational fluid dynamics（CFD）and the one in structural analysis， and the load can be given in the form of ...

Electromagnetic Radiation Space Field Construction Collected along the Road Based on Layered Radial Basis Function

Applied Sciences, 2023
The electromagnetic radiation (EMR) data collected along a road have a largely empty region overall, while they have a linear distribution locally. Moreover, the traditional spatial interpolation method is not suitable for the electromagnetic radiation ...

Moving-boundary problems solved by adaptive radial basis functions [PDF]

, 2010
The objective of this paper is to present an alternative approach to the conventional level set methods for solving two-dimensional moving-boundary problems known as the passive transport. Moving boundaries are associated with time-dependent problems and

A rescaled method for RBF approximation

, 2016
In the recent paper [8], a new method to compute stable kernel-based interpolants has been presented. This \textit{rescaled interpolation} method combines the standard kernel interpolation with a properly defined rescaling operation, which smooths the ...

A Robust Adaptive One‐Sample‐Ahead Preview Super‐Twisting Sliding Mode Controller

International Journal of Adaptive Control and Signal Processing, EarlyView.
Block Diagram of the Robust Adaptive One‐Sample‐Ahead Preview Super‐Twisting Sliding Mode Controller. ABSTRACT This article introduces a discrete‐time robust adaptive one‐sample‐ahead preview super‐twisting sliding mode controller. A stability analysis of the controller by Lyapunov criteria is developed to demonstrate its robustness in handling both ...

A reference solution of the flow over a circular cylinder at Re=40

, 2013
The classical problem of the flow over a circular cylinder at Reynolds number 40 is considered using an accurate pseudo-spectral code. A new set of boundary conditions is proposed to improve the representation of the infinite flow domain, especially in ...
