The primary motivation is the understanding of the evolution of isolated vortex lines for 3D Euler.
Many of our affiliates had previously used the Polycom Vortex line and were very impressed by the capability of the product and the support that was provided by Polycom.
By integrating Alacritech's high performance TOE Gigabit NIC, we are providing our customers with a 50% performance increase and the scalability they require with our Vortex line and our newly announced Palladium Store-100.
Among their topics are vortex lines in three-dimensional magnetic nanodots by Langevin simulation, magnetic properties of nanostructures in non-integer dimensions, magnetic anisotropy and magnetization reversal in self-organizing two-dimensional nanomagnets, magnetoferritin nanoparticles as a promising building block for three-dimensional magnonic crystals, and physical properties of two-dimensional crossover solids from an electro-elastic description.
Quickly after vortex lines snap away from each other, they could jerk and wiggle and form what are called "Kelvin waves.
Recent theory suggests the decay occurs through a Kelvin-wave cascade on the vortex lines which couples the initially large turbulent eddies to the short wavelength phonon spectrum of the liquid, yielding a characteristic rate of temperature rise.
When the magnetic fields are strong enough, they create an array of vortex lines around which electric currents swirl (SN: 11/27/93, p.
The interesting thing is that people saw masses of vortex lines in liquid helium for years and wanted to get rid of them," says Zurek.
In this case, the defects materialize as vortex lines -- tiny, invisible whirlpools of fluid that penetrate the liquid helium.
The trouble [with helium] is that you have to work at low temperatures, and you have a fairly hard time finding these vortex lines because you can't see them directly" says Zurek.
