An Efficient FDTD Method Based on Subgridding Technique and One-Step Leapfrog ADI-FDTD
IEEE Microwave and Wireless Technology Letters, 2023In this letter, a 3-D subgridding finite-difference time-domain (FDTD) approach is proposed. The calculation domain is divided into regions with dense meshes and regions with coarse meshes.

Depression Is the Leading Cause of Disability Around the World.
Journal of the American Medical Association (JAMA), 2017Potential Cause of Nodding Syndrome Identified Nodding syndrome, a rare form of epilepsy that has affected thousands of children between the ages of 5 and 15 years in East Africa, may be caused by an inappropriate immune reaction to the parasitic worm ...

In this paper, a new three-dimensional time-domain method for solving vector Maxwell's equations, called the precise-integration time-domain (PITD) algorithm, is proposed in order to eliminate the Courant-Friedrich-Levy (CFL) condition restraint. The new

Friedrichs Method in a Lyapunov Problem
Applicable Analysis, 2002By using the well-known Friedrichs extension and some a priori inequality, we obtain weak solutions of a Lyapunov equation. In particular, we show that the Lyapunov functions satisfying necessary and sufficient conditions in the domain of asymptotic stability of a singular point some dynamical system must be absolutely continuous.

An Optimized 3-D HIE-FDTD Method With Reduced Numerical Dispersion
IEEE Transactions on Antennas and Propagation, 2018Fast and accurate modeling of scatters with fine structural feature in one or two directions has significant practical and scientific importance. To fill such research gaps, a 3-D artificial anisotropy hybrid implicit–explicit finite-difference time ...

An explicit filtering method for large eddy simulation of compressible flows
, 2003A method for large eddy simulation (LES) is presented in which the sub-grid-scale modeling is achieved by filtering procedures alone. The procedure derives from a deconvolution model, and provides a mathematically consistent approximation of unresolved ...
