We propose a novel meshless deformable model for in vivo Left Ventricle (LV) 3D motion estimation and analysis based on tagged MRI (tMRI). The meshless deformable model can capture global deformations such as contraction and torsion with a few parameters, while track local deformations with Laplacian representation. In particular, the model performs well even when the control points (tag inters...

The large deformation analysis is one of major challenges in numerical modelling and simulation of metal forming. Although the finite element method (FEM) is a well-established method for modeling nonlinear problems, it often encounters difficulties for large deformation analyses due to the mesh distortion issues. Because no mesh is used, the meshless methods show very good potential for the la...

This paper reviews the developments and applications of meshfree method based on MLPG (Meshless Local Petrov Galerkin) in ocean engineering, primarily from work carried out at IIT Madras City, University London, UK. Apart discussing various stages model development, this will also reports its to small amplitude waves, wave overtopping breaking, porous layers, long run-up, vegetation, floating b...

We propose a novel algorithm for modeling interface motions. The interface is represented and is tracked using quasi-uniform meshless particles. These particles are sampled according to an underlying grid such that each particle is associated to a grid point which is in the neighborhood of the interface. The underlying grid provides an Eulerian reference and local sampling rate for particles on...

In this paper, a new partition of unity ± the synchronized reproducing kernel (SRK) interpolant ± is derived. It is a class of meshless shape functions that exhibit synchronized convergence phenomenon: the convergence rate of the interpolation error of the higher order derivatives of the shape function can be tuned to be that of the shape function itself. This newly designed synchronized reprod...

The non-Fourier effect in heat conduction is important in strong thermal environments and thermal shock problems. Generally, commercial FE codes are not available for analysis of non-Fourier heat conduction. In this study, a meshless formulation is presented for the analysis of the non-Fourier heat conduction in the materials. The formulation is based on the symmetric local weak form of the sec...

The spread of different material processing technologies has led to the novel methods developed for reinforcing structural members. One these approaches is add carbon nanotubes (CNTs) with distributions through matrix phase composite materials improve its properties. Due superior properties such as lightweight and high values elastic modulus, strain, failure CNTs can be used reinforce structure...

Abstract As the groundwater quantitative monitoring aimed to determine factors affecting aquifer behavior plays an important role in its regional management, studying temporal and spatial level variations requires a comprehensive network. Effort has been made this study introduce new linked simulation–optimization method, named MLPG-TLBO quantitatively monitor Birjand optimal points for piezome...

1. Introdu tion. There are plenty of appli ation papers in whi h kernels or radial basis fun tions are su essfully used for solving partial di erential equations by meshless methods. The usage of kernels is typi ally based on spatial interpolation at s attered lo ations, writing the trial fun tions entirely in terms of nodes [2℄. For stationary partial di erential equations, the dis retization ...

Abstract Nowadays, infiltration tactics are widely used to manage storm water in urban areas. These techniques and recognized around the world due their benefits, such as reducing negative consequences of urbanization, flow sewage systems recharging groundwater. Richards equation is one most well-known equations for simulating soil unsaturated area. In present study, a one-dimensional approach ...
