An accurate and stable alternating directional moving particle semi-implicit method for incompressible flow simulation

open access: yesAdvances in Mechanical Engineering, 2022
As a Lagrangian mesh free method, Moving Particle Semi-implicit (MPS) method can easily handle complex incompressible flow with free surface. However, some deficiencies of MPS method such as inaccurate results, unphysical pressure oscillation and ...

Isotopic meshing of implicit surfaces [PDF]

open access: yesThe Visual Computer, 2006
Implicit surfaces are given as the zero set of a function F : R3→R. Although several algorithms exist for generating piecewise linear approximations, most of these are based on a user-defined stepsize or bounds to indicate the precision, and therefore cannot guarantee topological correctness. Interval arithmetic provides a mechanism to determine global

Measuring learning that is hard to measure: using the PECSL model to evaluate implicit smart learning

open access: yesSmart Learning Environments, 2022
This paper explores potential ways of evaluating the implicit learning that may be present in autonomous smart learning activities and environments, reflecting on prior phenomenographic research into smart learning activities positioned as local journeys

Neural 3D reconstruction from sparse views using geometric priors

open access: yesComputational Visual Media, 2023
Sparse view 3D reconstruction has attracted increasing attention with the development of neural implicit 3D representation. Existing methods usually only make use of 2D views, requiring a dense set of input views for accurate 3D reconstruction.

MixNet: Mix different networks for learning 3D implicit representations

open access: yesGraphical Models, 2023
We introduce a neural network, MixNet, for learning implicit representations of 3D subtle models with large smooth areas and exact shape details in the form of interpolation of two different implicit functions.

A Numerical–Experimental Approach for Multi‐Matrix Fiber‐Reinforced Plastics Characterization Using Finite Element Model Updating

open access: yesAdvanced Engineering Materials, EarlyView.
A numerical–experimental framework is developed for characterizing multi‐matrix fiber‐reinforced polymers (MM‐FRPs) combining epoxy and polyurethane matrices. Harmonic bending tests are integrated with finite element model updating (FEMU) to simultaneously identify elastic and viscoelastic material parameters.
