The forward problem in Electrical Impedance Tomography (EIT) requires an accurate estimation of its solution. Although analytical solutions exist for a limited number of cases, there is no suitable analytical solution for the geometry of the human head. A commonly adopted method is the use of Finite Element Methods (FEM). However, the human head consists of layers, which include the scalp and C...

MOTIVATION There is a growing number of studies generating matched Illumina Infinium HumanMethylation450 and gene expression data, yet there is a corresponding shortage of statistical tools aimed at their integrative analysis. Such integrative tools are important for the discovery of epigenetically regulated gene modules or molecular pathways, which play key roles in cellular differentiation an...

This theoretical study describes the optical multilayer structure models leading to investigate Surface Plasmon Polariton (SPP) to an extern applied magnetic field at visible wavelenght using a 3D-FEM based on Comsol Multiphysics software. The layered structures include the amorphous silicon c-Si octahedral nanocrystals on the interface SiO2/dielectric were investigated to enhance the SPP inten...

The fast development of computer power and computational algorithms has made it possible to design complex transducers and arrays using computer simulation. Practical examples are given here for transducer modeling using 3-D finite element method (FEM) instead of the traditional 1-D equivalent circuit models. The merits and deficiencies of the frequency domain and time domain FEM formulations w...

The interaction of guided waves with non-axisymmetric damages in cylinders is studied. A three dimensional hybrid method involving the classical Finite Element Method (FEM) and the Semi-Analytical Finite Element (SAFE) technique is developed. The damage and its near field are analysed with the standard FEM. Then, eigenmode expansions of the solutions at both inlet and outlet cross-sections of t...

1. Background/Problem In real-time surgery simulation and planning, the Finite Element Method (FEM) is often used to simulate small and large deformation of human tissue for applications such as laparoscopy training [4], needle insertion planning [1], and image registration [2]. In using FEM, assumptions must be made about material properties and the scale of deformation of human tissues in and...

DUNE-FEM is a free discretization toolbox for parallel and adaptive scientific computing based on DUNE. The implementation of discretization schemes such as finite elements, finite volumes or discontinuous Galerkin schemes is based on abstractions that are very close to the mathematical description of the underlying methods. In this contribution we will give a compact overview on the design and...

With the use of the microdialysis method, the present study, performed on young, healthy, nonobese subjects of both genders, compares the effects of locally infused catecholamines on glycerol concentration and blood flow in abdominal (Abd) and femoral (Fem) adipose tissue. Physiological activation of the sympathetic nervous system through active tilt was also investigated. In both genders, extr...

Fluctuation Electron Microscopy (FEM) examines the scattering statistics from small volumes of thin amorphous materials to detect the presence of medium-range order (MRO) [1]. By now it has been thoroughly demonstrated, by both modeling and simulations, that FEM is extraordinarily sensitive to MRO, much more than high-resolution diffraction and high-resolution imaging. Experiments have confirme...
