Molecular dynamics simulation has been used to model pattern formation in three-dimensional Rayleigh-Bénard convection at the discrete-particle level. Two examples are considered, one in which an almost perfect array of hexagonally shaped convection rolls appears, the other a much narrower system that forms a set of linear rolls; both pattern types are familiar from experiment. The nature of th...

“Can brute-force high-contrast tomography techniques and image processing techniques retrieve textual content from damaged heritage materials?” The Dental Institute at Queen Mary University of London (QMUL) is the leading centre for very high contrast X-Ray Microtomography imaging. The Apocalypto Project is our collaboration with the heritage community and experts in Computer Vision systems in ...

We have numerically investigated Rayleigh-Bénard convection in binary mixtures assuming a thermal diffusion ratio that depends on the local temperature and changes its sign within the cell. The stationary instability has been found to precede the oscillatory one for a wide range of negative mean psi values. The bifurcation diagram for stationary rolls turns out to be qualitatively different fro...

When two-dimensional pattern-forming problems are posed on a periodic domain, classical techniques (Lyapunov-Schmidt, equivariant bifurcation theory) give considerable information about what patterns formed in the transition where featureless state loses stability. problem is whole plane, these still present. Recent work Swift-Hohenberg equation (an archetypal partial differential equation) has...

Abstract In metalworking, bending forming processes are used extensively for a wide range of applications referring to several industrial fields, such as oil&gas field, naval field or automotive field. cylinders and truncated cones process, three-point roll metal sheets represents concrete option, which mainly consists pyramid-type machines made two lower rolls top roll. Each can be designe...

A red tide rolls ashore in Puget Sound, Washington. Environmental changes, heightened awareness, and improved detection have increased the number of HABs reported each year.

BACKGROUND Recent detailed analyses of data on dietary sources of energy and nutrients in US children are lacking. The objective of this study was to identify food sources of energy and 28 nutrients for children in the United States. METHODS Analyses of food sources were conducted using a single 24-h recall collected from children 2 to 18 years old (n = 7332) in the 2003-2006 National Health ...

The problem of the indentation of a rubberlike layer bonded to a rigid cylinder and indented by another rigid cylinder is analyzed. The rubberlike layer is assumed to be made of a homogeneous Mooncy-Rivlin material. The materially and geometrically nonlinear problem is solved by using the finite-element code developed by the author. Results computed and presented graphically include the pressur...

Role-playing games (RPG’s) use a variety of methods for rolling dice to add randomness to the game. In the simplest form, a small number of identical dice are rolled and added, but more advanced forms involve cumulative re-rolling of 6’s, doubling the value of doubles, removing the lowest or highest result or counting the number of dice that are below a threshold, and many other weird and wonde...
