Abstract: The Galerkin method is used to solve numerically the nonlinear initial-boundary value problem describing the vertical temperature profile for a thermally coupled soil-atmosphere boundary layer in a simple physical setting. ...

Abstract: A dissipative Galerkin procedure is used to solve two hyperbolic problems on an irregular or variable grid. Both forced wave motions (Gaussian) and boundary induced wave propagations are considered. It is shown that results ...

Abstract: Low- and high-pass traditional recursive and implicit filters are reviewed. Some similarities and differences between these two forms are illustrated. The use of recursive filters in signal processing is contrasted with ...

Abstract: A multidimensional filter which selectively removes 2?x and 2?y noise is introduced. The filter is designed to be effective in finite area models with nonperiodic horizontal boundary conditions. An economical splitting ...
