The multi-block overset grid method is a powerful technique for high-fidelity computational fluid dynamics (CFD) simulations about complex aerospace configurations. The solution process uses a grid system that discretizes the problem domain by using separately generated but overlapping structured grids that periodically update and exchange boundary information through interpolation. For efficie...

In vitro whole cell patch-clamp recordings of stellate cells in layer II of medial entorhinal cortex show a subthreshold membrane potential resonance in response to a sinusoidal current injection of varying frequency. Physiological recordings from awake behaving animals show that neurons in layer II medial entorhinal cortex, termed "grid cells," fire in a spatially selective manner such that ea...

The assembly of overlapping grids is a key technology to deal with the relative motion multi-bodies in computational fluid dynamics. However, conventional implicit techniques for are often confronted problem complicated geometry analysis, and consequently, they usually have low parallel efficiency resulting from undifferentiated searching grid nodes. To this, method that employs two-step node c...

A 3-dimensional quasiperiodic lattice with overlapping unit cells is constructed using grid and projection methods pioneered by de Bruijn. Using Kronecker’s theorem the frequencies of all possible types of overlapping are found.

Grid cells in layer II of rat entorhinal cortex fire to spatial locations in a repeating hexagonal grid, with smaller spacing between grid fields for neurons in more dorsal anatomical locations. Data from in vitro whole-cell patch recordings showed differences in frequency of subthreshold membrane potential oscillations in entorhinal neurons that correspond to different positions along the dors...

Algorithmic skeletons are polymorphic higher-order functions that represent common parallelization patterns. They can be used as the building blocks of parallel applications by integrating them into a sequential language. In this paper we present a skeleton-based approach to manage overlapping of distributed grids, which occur in parallel adaptive multigrid algorithms. Overlapping is necessary ...

Motion confidence measures aim to identify how well an image patch determines image motion. These kinds of confidence measures are commonly used to select points for optical flow estimation and feature tracking. The brute force approach of computing confidence for every image patch is inefficient, especially when the patches are large. The faster approach of computing confidence for a regular g...
