Caged Ball Valves

Some articles on valves, valve, ball, balls:

Artificial Heart Valve - Mechanical Valves - Fluid Mechanics
... is a debilitating side effect of high shear stresses created by the design of the valves ... An ideal heart valve from an engineering perspective would produce minimal pressure drops, have small regurgitation volumes, minimize turbulence, reduce prevalence of high stresses, and ... One measure of the quality of a valve is the effective orifice area (EOA), which can be calculated as follows where is the root mean square systolic/diastolic ...
Banach–Tarski Paradox
... paradox is a theorem in set-theoretic geometry which states the following Given a solid ball in 3‑dimensional space, there exists a decomposition of the ball into a finite ... a different way to yield two identical copies of the original ball ... form of the theorem implies that given any two "reasonable" solid objects (such as a small ball and a huge ball), either one can be reassembled into the other ...

Banach–Tarski Paradox - Obtaining Infinitely Many Balls From One
... Using the Banach–Tarski paradox, it is possible to obtain k copies of a ball in the Euclidean n-space from one, for any integers n ≥ 3 and k ≥ 1 ... a ball can be cut into k pieces so that each of them is equidecomposable to a ball of the same size as the original ... These results then extend to the unit ball deprived of the origin ...
Quarter Seam
... is the tiny seam which runs around a cricket ball at 90 degrees to the large, raised seam ... can be 'picked at' - loosening the threads - in order to create conventional swing when the ball is relatively new, more recently, an understanding has evolved that ... can be as easily replaced before the end of the over, when the ball is due to be inspected by the umpires ...
