3D tooth semi-closed hole-filling algorithm based on the moving least-squares method

open access: yesVirtual Reality & Intelligent Hardware
Large-area semi-closed holes on the lateral surfaces of tooth models can cause difficulties in subsequent orthodontic tasks, such as collision detection and finite element analysis, and may affect the accuracy and stability of further processing.

A Online NIR Sensor for the Pilot-Scale Extraction Process in Fructus Aurantii Coupled with Single and Ensemble Methods

open access: yesSensors, 2015
Model performance of the partial least squares method (PLS) alone and bagging-PLS was investigated in online near-infrared (NIR) sensor monitoring of pilot-scale extraction process in Fructus aurantii.

An Efficient Estimator for Moving Target Localization Using Multi-Station Dual-Frequency Radars

open access: yesSensors, 2017
Localization of a moving target in a dual-frequency radars system has now gained considerable attention. The noncoherent localization approach based on a least squares (LS) estimator has been addressed in the literature.

MLS-Based Numerical Manifold Method for Modeling the Cracked Rock Considering the Contact of the Crack Surface

open access: yesFrontiers in Earth Science, 2022
To simulate the moving boundary problems, the moving least square–based numerical manifold method, abbreviated as MLS-based NMM, was proposed. The MLS-based NMM has been applied successfully to open crack problems, which exhibits the high accuracy and ...

An enforced essential boundary condition by penalty method in the element-free Galerkin (EFG) methods

open access: yesVietnam Journal of Mechanics, 2009
A meshless approach to the analysis of two-dimensional elasticity problems by the Element-Free Galerkin (EFG) method is presented. This method is based on moving least squares approximant (MLS).

A Novel Spatio-Temporal Fully Meshless Method for Parabolic PDEs

open access: yesMathematics, 2022
We introduce a meshless method derived by considering the time variable as a spatial variable without the need to extend further conditions to the solution of linear and non-linear parabolic PDEs.

The MLPG analysis of crack problems in magnetoelectroelastic solids [PDF]

open access: yesComputer Methods in Materials Science, 2011
A meshless method based on the local Petrov-Galerkin approach is applied for boundary value problems with cracks in magnetoelectroelastic solids. A unit step function is used as the test functions in the local weak-form.

Some Estimation Methods for a Random Coefficient in the Gegenbauer Autoregressive Moving-Average Model

open access: yesMathematics
The Gegenbauer autoregressive moving-average (GARMA) model is pivotal for addressing non-additivity, non-normality, and heteroscedasticity in real-world time-series data.

A GALERKIN APPROXIMATION METHOD INCLUDING SPACE DIMENSIONAL REDUCTION - APPLIED FOR SOLUTION OF A HEAT CONDUCTION EQUATION [PDF]

open access: yesApplied Computer Science, 2012
A multivariate data fitting procedure, based on the Galerkin minimization method, is studied in this paper. The main idea of the developed approach consists in projecting the set of data points from the original, higherdimensional space, onto a line ...
