An efficient dynamic uniform Cartesian grid system for inundation modeling

Wall-Layer Modeling for Cartesian Grid Solver Using an Overset Boundary Layer Orthogonal Curvilinear Grid

Wall-layer modeling for a Cartesian grid solver is developed by coupling an orthogonal curvilinear grid solver using overset grid interpolation and coupled pressure Poisson solver. A thin wall-layer grid is considered sufficient to resolve the boundary layer. Initial validation is performed for laminar flows over a circular cylinder, where the wall-layer model shows up to 10% improvement in the...

A multilevel Cartesian non-uniform grid time domain algorithm

A novel algorithm to rapidly compute transient wave fields radiated by three-dimensional temporally band-limited source constellations is proposed. Just like its two-level predecessor, the Multilevel Cartesian Non-uniform Grid Time Domain (ML_CNGTD) algorithm leverages the observation that transient wave fields generated by temporally band-limited and spatially confined source constellations ca...

Dynamic Demand Management in an Airconditioner System by Frequency Control in Smart Grid Environment

As there is a rapid growth both in the number of power consumers and also the limitations energy resources, it is clearly accepted that the old version of power grid must change into smart grid from head to toe. One of the most important advantages of smart grid which makes it much more exclusive rather than other typical systems is the two-way connectivity between the utility and the costumers...

An efficient coding theory for a dynamic trajectory predicts non-uniform allocation of entorhinal grid cells to modules

Grid cells in the entorhinal cortex encode the position of an animal in its environment with spatially periodic tuning curves with different periodicities. Recent experiments established that these cells are functionally organized in discrete modules with uniform grid spacing. Here we develop a theory for efficient coding of position, which takes into account the temporal statistics of the anim...
