The conducting medium containing these regions of interest is assumed to be an infinite half space, an infinite cylinder or a finite sphere.
For image reconstruction, batches of cardiac-synchronized readouts are used to form three-dimensional navigators from a fully sampled central k-space cylinder.
In addition to upward refraction, it will be shown that these periodically spaced cylinder formations can simultaneously benefit from band-gap phenomena.
For widely spaced cylinders, P/D>2.5, the Strouhal numbers are close to the single-cylinder value.
For example, the total force exerted by two optimally spaced cylinders exceeds by 53% the total force of two cylinders with no spacing when Re=20.
Three-dimensional scattering of elastic waves by an array of parallel and periodically spaced cylinders has been studied.
For moderately spaced cylinders, 1.5⩽P/D⩽2.5, two distinct Strouhal numbers are measured when α>30°, but there is some scatter in the Strouhal data when α<30°.
Particular attention is paid to the problem of wake-induced vibrations of closely spaced cylinders: wind tunnel tests and a mathematical model to understand and simulate this phenomenon are presented.
We construct diffeomorphism-invariant functionals on the space of cylinder functions from "spin networks": graphs inMwith edges labeled by representations ofGand vertices labeled by intertwining operators.
We consider parabolic equations of porous medium type of the formut−divA x,t,u,Du)="μinET, in some space time cylinder ET. The most prominent example covered by our assumptions is the classical porous medium equationut−Δum="μinET, with m≥1.
cylinder space (displacement or working cylinder), heat exchanger (cooler or heater for external heat transfer), regenerator (internal heat transfer).
