A Semi-implicit Semi-lagrangian Shallow-water Model for Massively Parallel Processors
The formulation of a grid point shallow-water model proposed by C^ ot e and Stan-iforth is described. The model employs a hybrid nite-volume//nite-element spatial discretisation on a staggered Arakawa B type grid, where the geopoten-tial is computed at grid points and the wind u is found at grid cell centers. Time integration is based upon a two-time-level semi-implicit, semi-Lagrangian scheme....

متن کاملA Semi-Implicit Semi-Lagrangian Finite-Element Shallow-Water Ocean Model
The nite-element, semi-implicit, and semi-Lagrangian methods are combined together to solve the shallow-water equations using unstructured triangular meshes. Triangular nite elements are attractive for ocean modeling because of their exibility for representing irregular boundaries and for local mesh re nement. A \kriging" interpolator is used for the semi-Lagrangian advection, leading to an acc...
متن کاملXML Schema Containment Checking Based on Semi-implicit Techniques
XML schemas are computer languages defining grammars for XML (Extensible Markup Languages) documents. Containment checking for XML schemas has many applications, and is thus important. Since XML schemas are related to the class of tree regular languages, their containment checking is reduced to the language containment problem for non-deterministic tree automata (NTAs). However, an NTA for a pr...
متن کاملA Numerical Study for the Solution of Time Fractional Nonlinear Shallow Water Equation in Oceans
In this paper, an analytical solution for the coupled one-dimensional time fractional nonlinear shallow water system is obtained by using the homotopy perturbation method (HPM). The shallow water equations are a system of partial differential equations governing fluid flow in the oceans (sometimes), coastal regions (usually), estuaries (almost always), rivers and channels (almost always). The g...
