Abstract Provably Good Moving Least Squares [PDF]

open access: yes, 2008
We analyze a moving least squares algorithm for reconstructing a surface from point cloud data. Our algorithm defines an implicit function I whose zero set U is the reconstructed surface.

Learning Representation of Turbulent Vector Fields via Efficient Moving Least Squares Based on Monte Carlo Method

open access: yesIEEE Access
In this study, we develop a numerical method to represent turbulent flow in various 2D vector fields using the Monte Carlo method-based MLS (Moving Least Squares) from a density field and express it as a learning representation through a neural network ...

The Process of Generating Single Large Combined Cloud for Grid-Free Solvers [PDF]

open access: yes, 2013
Dealing with moving body problems, where one component moves relatively with respect to other, is a difficult task in CFD due to the efforts needed in grid handling for every delta change in position of the moving component.

Stability Analysis of Curved Beams Based on First-Order Shear Deformation Theory and Moving Least-Squares Approximation

open access: yesBuildings
Based on the first-order shear deformation theory (FSDT) and moving least-squares approximation (MLS), a new meshfree method that considers the effects of geometric nonlinearity and the pre- and post-buckling behaviors of curved beams is proposed.
