Comparison results for the Stokes equations [PDF]
arXiv, 2014 This paper enfolds a medius analysis for the Stokes equations and compares different finite element methods (FEMs). A first result is a best approximation result for a P1 non-conforming FEM.

Preasymptotic Error Analysis of Higher Order FEM and CIP-FEM for Helmholtz Equation with High Wave Number [PDF]
arXiv, 2014 A preasymptotic error analysis of the finite element method (FEM) and some continuous interior penalty finite element method (CIP-FEM) for the Helmholtz equation in two and three dimensions is proposed.

FEM: feature-enhanced map [PDF]
Acta Crystallographica Section D Biological Crystallography, 2015 A method is presented that modifies a 2mFobs−DFmodelσA-weighted map such that the resulting map can strengthen a weak signal, if present, and can reduce model bias and noise. The method consists of first randomizing the starting map and filling in missing reflections using multiple methods.

A probabilistic finite element method based on random meshes: Error estimators and Bayesian inverse problems [PDF]
Comput. Methods Appl. Mech. Engrg. 384 (2021) 113961, 2021 We present a novel probabilistic finite element method (FEM) for the solution and uncertainty quantification of elliptic partial differential equations based on random meshes, which we call random mesh FEM (RM-FEM). Our methodology allows to introduce a probability measure on standard piecewise linear FEM. We present a posteriori error estimators based

FEM modelling of the evolution of corrosion cracks in reinforced concrete structures
Reliability and Optimization of Structural Systems, 2020 : Corrosion cracks are caused bythe increased volume of corrosion products during the corrosion of the reinforcement. After corrosion initiation the rust products from the corroded reinforcement will initially fill the porous zone near the reinforcement ...

Dense Tactile Force Estimation using GelSlim and inverse FEM [PDF]
IEEE International Conference on Robotics and Automation, 2018 In this paper, we present a new version of tactile sensor GelSlim 2.0 with the capability to estimate the contact force distribution in real time. The sensor is vision-based and uses an array of markers to track deformations on a gel pad due to contact ...

FEM-Based Mechanics Modeling of Bio-Inspired Compliant Mechanisms for Medical Applications
bioRxiv, 2020 Compliant mechanisms are widely used in the design of medical robotics and devices because of their monolithic structure and high flexibility. Many compliant mechanisms derive their design ideas from nature, since the structure of biological organisms ...
