Hybrid FEM/MoM methods combine the finite element method (FEM) and the method of moments (MoM) to model inhomogeneous unbounded problems. These two methods are coupled by enforcing the continuity of tangential fields on the boundary that separates the FEM and MoM regions. When modeling complex geometries with many elements on the boundary, the MoM part of the problem is the bottleneck of the hy...

Three dimensional image reconstruction for multi-modality optical spectroscopy systems needs computationally efficient forward solvers with minimum meshing complexity, while allowing the flexibility to apply spatial constraints. Existing models based on the finite element method (FEM) require full 3D volume meshing to incorporate constraints related to anatomical structure via techniques such a...

The Finite Element Method (FEM) has been used in the broad field of continuum mechanics in engineering disciplines for several decades. However, recently, some scholars have attempted to apply the method to social science phenomena. What is the scope of using FEM in social science-related fields? Anchored in the literature on social sciences, this paper, firstly, reviews the scope of using FEM ...

Patients suffering from the acute respiratory distress syndrome (ARDS) requires thoracic electrical impedance tomography (EIT) for the monitoring their conditions ranging from dynamic shifting of body fluids to lung aeration right at the bedside. More objectively, EIT-derived numeric parameters would help the physician to evaluate the state of the lung. Thus, here we have performed a Finite Ele...

This study presents a new procedure based on Artificial Neural Network (ANN) for identification of double cracks in Functionally Graded Beams (FGBs). A cantilever beam is modeled using Finite Element Method (FEM) for analyzing a double-cracked FGB and evaluation of its first four natural frequencies for different cracks depths and locations. The obtained FEM results are verified against availab...

This paper presents an overview on applications of hybrid finite element method (FEM) to heat transfer analysis of skin tissue materials. Recent developments on the hybrid fundamental solution based FEM of heat transfer in skin tissues are described. Formulations for all cases are derived by means of modified variational functional and fundamental solutions. Generation of elemental stiffness eq...

Radiofrequency (RF) coil phased arrays are getting more and more important for accelerating the imaging speed and for gaining better signal to noise ratio (SNR) in magnetic resonance imaging (MRI). The approach is conceptually similar to phased array used in radar techniques hence it is used to be called MRI phased array coils. To get maximum benefits from this technique, coil and preamp decoup...

The Modular Inversion Program (MIP) is a processing and development tool designed for retrieval and mapping of hydro-biological parameters obtained from multiand hyperspectral remote sensing measurements. The architecture of the program binds a set of general and transferable computational schemes in a chain, connecting bio-physical parameters with the measured reflected radiance. The radiative...
