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.

Direct-Splitting-Based CN-FDTD for Modeling 2D Material Nanostructure Problems
IEEE Open Journal of Antennas and Propagation, 2020 Incorporating a truncation of the complex-frequency-shifted perfectly matched layer (CFS-PML), the direct-splitting- based Crank-Nicolson finite-difference time-domain (CNDS-FDTD) is developed and applied to the infrared two-dimensional layered material (

Detection of fixed points in spatiotemporal signals by clustering method
, 2000 We present a method to determine fixed points in spatiotemporal signals. A 144-dimensioanl simulated signal, similar to a Kueppers-Lortz instability, is analyzed and its fixed points are reconstructed.Comment: 3 pages, 3 ...

Some observations on a new numerical method for solving Navier-Stokes equations [PDF]
An explicit-implicit technique for solving Navier-Stokes equations is described which, is much less complex than other implicit methods. It is used to solve a complex, two-dimensional, steady-state, supersonic-flow problem.

Regeneration of Stochastic Processes: An Inverse Method
, 2005 We propose a novel inverse method that utilizes a set of data to construct a simple equation that governs the stochastic process for which the data have been measured, hence enabling us to reconstruct the stochastic process. As an example, we analyze the
