We have emphasized the importance of developing a better understanding of the dynamical & statistical origin of the positivity of vortex-stretching rate 〈ω̄! S!ω̄!〉 > 0. For the fine-grained vorticity (! → 0), this is important in Taylor’s proposed mechanism for production of energy dissipation 〈ν|ω|2〉. For ! in the inertial-range, we have seen that the flux of energy to small-scales is proportio...

Flow simulation is a computational tool for exploring science and technology involving flow applications. It can provide cost-effective alternatives or complements to laboratory experiments, field tests and prototyping. Flow simulation relies heavily on high performance computing (HPC). We view HPC as having two major components. One is advanced algorithms capable of accurately simulating compl...

I present a new focal-plane analog VLSI sensor that estimates optical flow in two visual dimensions. The chip significantly improves previous approaches both with respect to the applied model of optical flow estimation as well as the actual hardware implementation. Its distributed computational architecture consists of an array of locally connected motion units that collectively solve for the u...

I present a new focal-plane analog very-large-scale-integrated (aVLSI) sensor that estimates optical flow in two visual dimensions. Its computational architecture consists of a two-layer network of locally connected motion units that collectively estimate the optimal optical flow field. The applied gradient-based optical flow model assumes visual motion to be translational and smooth, and is fo...

Ileal endogenous amino acid (IEAA) flow in turkey poults was determined at 2 experimental locations on d 5, 15, and 21 posthatch using 3 methods, namely a N-free diet (NFD), a highly digestible protein (casein), and the regression method, obtained by regressing IEAA flow against dietary casein levels. The diets were semipurified and contained 0, 50, 100, or 150 g of casein/kg of diet as the sol...

this 4x2 factorial study compared the effect of four sites (a=siphon as upstream, andb=shahdera, c=sunder and d= balloki as 3 downstream sites) during low and high flow seasons of river ravion metal cconcentrations in muscles from cirrhinus (c) mrigala, a bottom feeder carp. while weight andlength of studied specimens did not differ significantly (p>0.05). overall metal accumulations appeared i...

In this paper we consider new geometric flow equations, called D-flow, which describe the variation of space-time geometries under change number dimensions. The D-flow is originating from non-trivial dependence volume manifolds on dimensions and it driven by certain curvature invariants. We will work out specific examples equations their solutions for case D-dimensional spheres Freund-Rubin Com...
