Implicit-explicit (IMEX) schemes have been widely used, especially in conjunction with spectral methods, for the time integration of spatially discretized partial differential equations (PDEs) of ...

In this article, a novel multigrid-based method is developed for modeling of electric fields and currents in electrically anisotropic and heterogeneous media. The method is useful for numerical ...

Chinese archaeologists announced Wednesday that they have discovered the country's earliest multigrid city layout at a large relics site that dates back 3,500 to 3,800 years.

A multigrid inversion approach that uses variable resolutions of both the data space and the image space is proposed. Since the computational complexity of inverse problems typically increases with a ...
