We present a new discretization method for homogeneous convectiondiffusion-reaction boundary value problems in 3D that is a non-standard finite element method with PDE-harmonic shape functions on polyhedral elements. The element stiffness matrices are constructed by means of local boundary element techniques. Our method, which we refer to as a BEM-based FEM, can therefore be considered a local ...

The unrivaled combination of speed, accuracy, and ease of use make CAE software that employs the BEM ideally suited for analyses involving shielding of MRI and NMR systems.

Um eletrodo de carbono vítreo modificado com poli(safranina T) foi utilizado para a determinação simultânea de epinefrina (EP) e ácido úrico (AU) na presença de ácido ascórbico (AA). Correntes eletrocatalíticas aumentadas e potenciais bem separados para EP e AU foram observados. As correntes de pico anódico de EP e AU foram lineares em função das concentrações correspondentes, na faixa de 6,0×1...

In this paper, we describe a new hybrid method which combines the boundary element method (BEM) and the nite element method (FEM) to calculate the circuit models for layout dependent capacitances in VLSI circuits. The hybrid method which we present does more than solving a particular eld problem, it produces a good physical circuit model for the interface between the regions where the BEM and t...

Ovomacroglobulin and LDL fraction of egg yolk were effective to maintain the growth of established human cancer cell lines (Kato III, QG-90, Raji). A serum-free medium (BEM-841) containing 10 mM HEPES, 50 micrograms/ml of ovomacroglobulin, 0.1% (V/V) of LDL fraction of egg yolk, 10(-8) M catalase, 5 micrograms/ml of insulin, 5 micrograms/ml of transferrin, 5 ng/ml of selenium, 1 mg/ml of BSA, a...

Cortical potentials are estimated from scalp potentials using a realistically shaped inhomogeneous head model, by means of the boundary element method (BEM). A new adaptive algorithm has been developed to achieve high accuracy to link directly the cortical potentials to the scalp potentials in a realistically shaped inhomogeneous head model including the thin low-conductivity skull layer. Compu...

One challenge to predict output performance characteristics of switched reluctance machines (SRM) is the accurate estimation of the minimum inductance of the stator phase at unaligned position of the rotor. In this paper, boundary element method (BEM) is used for this purpose while avoiding time-consuming numerical integrations. So, the method is investigated in terms of accuracy and computatio...

The fast and accurate computation of the electric forces that drive the motion of charged particles at the nanometer scale represents a computational challenge. For this kind of system, where the discrete nature of the charges cannot be neglected, boundary element methods (BEM) represent a better approach than finite differences/finite elements methods. In this article, we compare two different...
