High-frequency analysis of the efficiency of a local approximate DtN2 boundary condition for prolate spheroidal-shaped boundaries
(Wave Motion, 2010-12-31)
The performance of the second-order local approximate DtN boundary condition suggested in  is investigated analytically when employed for solving high-frequency exterior Helmholtz problems with elongated scatterers. ...
Arithmetic method of double-injection-electrode model for resistivity measurement through metal casing
(IEEE Transactions on Geoscience and Remote Sensing, 2010-12-31)
Through-casing resistivity (TCR) measurement instruments such as Cased Hole Formation Resistivity are extensively used for the dynamic monitoring of oil reservoirs during the production phase in oil wells to evaluate the ...
On global and local mesh refinements by a generalized conforming bisection algorithm
(Journal of Computational and Applied Mathematics, 2010-12-31)
We examine a generalized conforming bisection (GCB-)algorithm which allows both global and local nested refinements of the triangulations without generating hanging nodes. It is based on the notion of a mesh density function ...
