A third-order multirate time-stepping based on an SSP Runge–Kutta method is applied to solve the three-dimensional Maxwell’s equations on unstructured tetrahedral meshes. This allows for an evolution of the solution on fine and coarse meshes with

A third order type II WENO finite volume scheme for tetrahedral unstructured meshes is applied to the numerical solution of Maxwell’s equations. Stability and accuracy of the scheme are severely affected by mesh distortions, domain geometries, and

SUMMARY A new hybrid finite-volume time-domain integral equation (FVTD/IE) algorithm for the solution of Maxwell’s Equations on unstructured meshes of arbitrary flat-faceted volume elements is presented. A time-domain IE-based numerical algorithm i

This paper presents a simple and fast deblurring algorithm. Assuming a Gaussian blur, the exact solution requires the solution of the backward heat equation which is an ill-posed problem. Our solution consists of a truncation of a Neumann's expansion

A domain decomposition method is used to solve a Gaussian curvature driven flow to denoise digital images. The algorithm is embarrassingly parallel and is ideal for parallel computers. We use the scheme of Lee–Keun [Noise removal based on nonlinear

During ice storms, ice forms on high voltage electrical lines. This ice formation often results in downed lines and has been responsible for considerable damage to life and property as was evidenced in the catastrophic ice storm of Quebec recently. T
