Building Spectral Element Dynamic Matrices Using Finite Element Models of Waveguide Slices and Elastodynamic Equations

Shock and Vibration, 2013
Structural spectral elements are formulated using the analytical solution of the applicable elastodynamic equations and, therefore, mesh refinement is not needed to analyze high frequency behavior provided the elastodynamic equations used remain valid ...

Internal dynamics around static-deformation FEM states [PDF]

, 2005
Constant velocity or constant force FEM solutions are static-deformation states, where the elastic deformation is stationary. These are the typical operation conditions.

Semantic 3D Reconstruction with Finite Element Bases

, 2017
We propose a novel framework for the discretisation of multi-label problems on arbitrary, continuous domains. Our work bridges the gap between general FEM discretisations, and labeling problems that arise in a variety of computer vision tasks, including ...

Facilitators of Adherence to the Study Pill in the FEM-PrEP Clinical Trial

PLoS ONE, 2015
Introduction FEM-PrEP did not demonstrate a reduction in HIV acquisition because of low study pill adherence. Yet, plasma and intracellular drug concentrations indicated that some participants had evidence of recent pill use.

Nonlinear Robust Techniques Applied to Control the Stability of an Electric Tricycle

IEEE Access
This paper presents an original application of Sliding Mode (SM) control to stabilize an electric tricycle prototype using an on-board servomotor. SM controllers are known for their robustness against noise, disturbances, and model uncertainties.

Simplification of FEM-Models on Cell BE [PDF]

, 2010
Preparing a CAD model for Finite Element (FE) analysis can be a time-consuming task, where shape and mesh simplifications play an important role. It is important that the simplified model has the same mechanical properties as the original one, and that the deviation from the original stays within a given tolerance.

Implementation of $hp$-adaptive discontinuous finite element methods in Dune-Fem [PDF]

arXiv, 2016
In this paper we describe generic algorithms and data structures for the implementation of $hp$-adaptive discontinuous finite element methods in the Dune-Fem library. Special attention is given to the often tedious and error-prone task of transferring user data during adaptation.
