Skeletons are useful shape abstractions and have varied applications in visualization. The complexity of the desired skeletal structure depends on the application. Current techniques for extracting skeletons do not allow control over the complexity. In this paper, we describe an algorithm which uses a thinness parameter to control the density of the skeleton. We present applications from CFD an...

A three-dimensional (3-D) particle-in-cell (PIC) simulation of the whistler anisotropy instability is carried out for a collisionless, homogeneous, magnetized plasma with βe = 0.10. This is the first 3-D PIC simulation of the evolution of enchanced fluctuations from this growing mode driven by an anisotropic electron velocity distribution with T⟂e∕T∥e>1 where ⟂ and ∥ represent directions perpen...

The authors have carried out an important service by their meta-analysis, which strengthens the evidence that plaque characteristics are strongly associated with clinical outcomes. They have shown clearly that ulceration is a feature of plaques that are vulnerable to rupture; intraplaque hemorrhage is also associated with events in their linear analysis. In the search for identifying patients w...

A method to image random three-dimensional source distributions is proposed. We show that, by using a Michelson stellar interferometer in a prescribed fashion, one is able to measure a special form of a threedimensional degree of coherence. The inverse Fourier transform of this coherence function yields the threedimensional intensity distribution of the source as seen from the paraxial far zone.

A laboratory-generated hierarchical, fully heterogeneous aquifer model (FHM) provides a reference for developing and testing an upscaling approach that integrates large-scale connectivity mapping with flow and transport modeling. Based on the FHM, three hydrostratigraphic models (HSMs) that capture lithological (static) connectivity at different resolutions are created, each corresponding to a ...

Bushehr Bay is situated along the northern Iranian coasts of the Persian Gulf, between 28°52΄ and 29°5΄ north latitude and 50°42΄ and 50°52΄east longitude. In this study COHERENS, which is a threedimensional hydrodynamic model, was employed to simulate surface and under surface currents in the Bushehr Bay. The atmospheric forces and four main tidal constituents M2, S2, K1, O1 and also boundary ...
