Known as Synchronized Position, Hold, Engage and Reorient Experimental Satellites (Spheres for short), they are roughly the same size as bowling balls and are being used to test how the astronauts working at the space station can assemble spacecraft, maintain satellites and conduct emergency repairs in zero gravity up there.
Expressing the ratio of wear constants on the basis of geometrical experimental variables for sphere and disc, it also aims to reduce time consumption in profilometry sessions and to split real-time linear wear curves for mating members from the overall approach pattern.
More recently "Lixiviation: Ciani/Musica Inc. 1969-1985," an exhilarating compilation issued by Finders Keepers/B-Music last February, has renewed interest in the work of Suzanne Ciani, an Indiana-born composer whose output bridged experimental and commercial spheres, and who became a prominent New Age recording artist in the 1980s.
Yet even as fiction, the idea provided a compelling germ for the conductor Alan Pierson, the writer Andrew Kupfer and the director Nigel Maister to concoct a swirling, heady meditation on the intersection of experimental and commercial spheres, and of social and aesthetic agendas.
This experimental setup prevents spheres from falling before a stable temperature above the liquidus is established and thus avoids difficulties in evaluating viscosities from velocities of spheres falling through a partially molten sample.
Growing out of rock and electronic music, and operating outside the state-supported classical sphere, the experimental scene in China has existed for barely a decade.
Defining an effective diameter D of the rectangular duct with a falling sphere, the experimental wall factor data have been correlated by means of a single relationship for rectangular ducts of arbitrary geometry including the parallel plates and square ducts.
For normal shock waves, our numerical results are compared with a finite difference solution of the Boltzmann equation for hard sphere molecules, experimental data, and molecular dynamics simulation of argon using the realistic Lennard Jones potential.
Assuming the effective area for mass transfer to be equal to the external surface area of the spheres, the experimental values of the average gas solids mass transfer coefficient were determined to amount to approximately 40 80% of the values calculated from the well-known Ranz Marshall correlation for a single sphere in an undisturbed gas flow.
The agreements of the simulation results and experimental study where Bi spheres and Bi/GO nanohybrids were applied as direct plasmonic photocatalysts were discussed for the first time.
