Coupling of Point Collocation Meshfree Method and FEM for EEG Forward Solver

For solving electroencephalographic forward problem, coupled method of finite element method FEM and fast moving least square reproducing kernel method FMLSRKM which is a kind of meshfree method is proposed. Current source modeling for FEM is complicated, so source region is analyzed usingmeshfreemethod. First order of shape function is used for FEM and second order for FMLSRKM because FMLSRKM ...

Image Reconstruction in 3D Magnetic Induction Tomography using a FEM Forward Model

The inverse problem in 3D eddy current imaging is ill-posed and non-linear. The most commonly used image reconstruction algorithms for electrical imaging are based on a linear approximation (the Jacobian Matrix). We start with an initial conductivity distribution. The forward problem is solved and the predicted voltages compared with the calculated voltages from the Finite Element model. The co...

ACTIVE EARTH PRESSURE IN COHESIVE-FRICTIONAL SOILS USING FEM AND OPTIMIZATION

Calculation of lateral earth pressure on retaining walls is one of the main issues in geotechnics. The upper and lower bound theorems of plasticity are used to analyze the stability of geotechnical structures include bearing capacity of foundations, lateral earth pressure on retaining walls and factor of safety of slopes. In this paper formulation of finite element limit analysis is introduced ...

Discovering potential user browsing behaviors using custom-built apriori algorithm

Most of the organizations put information on the web because they want it to be seen by the world. Their goal is to have visitors come to the site, feel comfortable and stay a while and try to know completely about the running organization. As educational system increasingly requires data mining, the opportunity arises to mine the resulting large amounts of student information for hidden useful...

Modeling and simulation of forward Al extrusion process using FEM

The main objective of this paper is to study the effect of extrusion parameters (extrusion stresses and temperature) and die geometry, i.e. extrusion radius, on the extruded aluminum quality using FEM Simulation Technique. For this purpose, the general FEA Software ABAQUS was used to set up the finite element model of the warm aluminum extrusion in two dimensions (2D). Aluminum alloy Al-2014 wa...
