Singularity Processing Method of Microstrip Line Edge Based on LOD-FDTD

International Journal of Antennas and Propagation, 2014
In order to improve the performance of the accuracy and efficiency for analyzing the microstrip structure, a singularity processing method is proposed theoretically and experimentally based on the fundamental locally one-dimensional finite difference ...

Discontinuous Galerkin Methods for Friedrichs’ Systems. Part II. Second‐order Elliptic PDEs [PDF]

SIAM Journal on Numerical Analysis, 2006
This paper is the second part of a work attempting to give a unified analysis of discontinuous Galerkin methods. The setting under scrutiny is that of Friedrichs’ systems endowed with a particular $2 \times 2$ structure in which one unknown can be eliminated to yield a system of second-order elliptic-like PDEs for the remaining unknown.

Space-Time Discontinuous Galerkin Methods for Weak Solutions of Hyperbolic Linear Symmetric Friedrichs Systems

Journal of Scientific Computing, 2022
AbstractWe study weak solutions and its approximation of hyperbolic linear symmetric Friedrichs systems describing acoustic, elastic, or electro-magnetic waves. For the corresponding first-order systems we construct discontinuous Galerkin discretizations in space and time with full upwind, and we show primal and dual consistency.

Asymptotic analysis of Leray solution for the incompressible NSE with damping

Demonstratio Mathematica
In 2008, Cai and Jiu showed that the Cauchy problem of the Navier-Stokes equations, with damping α∣u∣β−1u\alpha {| u| }^{\beta -1}u for α>0\alpha \gt 0 and β≥1\beta \ge 1 has global weak solutions in L2(R3){L}^{2}\left({{\mathbb{R}}}^{3}).

A Compact Unconditionally Stable Method for Time-Domain Maxwell's Equations

International Journal of Antennas and Propagation, 2013
Higher order unconditionally stable methods are effective ways for simulating field behaviors of electromagnetic problems since they are free of Courant-Friedrich-Levy conditions. The development of accurate schemes with less computational expenditure is

Global Affinities: The Natural Method and Anomalous Plants in the Nineteenth Century

HoST, 2021
Approaching from an analysis of the work of Robert Brown (1773-1858) and Friedrich Welwitsch (1806–1872) on Rafflesia and Welwitschia, this article explores how the “natural method” became a tool for understanding extra-European flora in the nineteenth ...

Transferências e apropriações de saberes: Friedrich Bieri e a matemática para o ensino primário - Knowledge transferences and appropriations: Friedrich Bieri and the mathematic to the primary school

História da Educação, 2015
A partir da análise da obra de Friedrich Bieri (1844-1924), um suíço que emigrou para o Brasil no século 19, identificamos apropriações de saberes produzidos em países de língua alemã no ensino brasileiro.
