Effect of Vacuum Magnetic Well on Magnetohydrodynamic Stability in Heliotron-E-like Configurations with High Shear

The v acuum magnetic field o f the H elio tron-E device [1, 2] is a high-shear 1 = 2 stellarator with a large average magnetic hill, a high rotat ional t ran s ­ fo rm at the p lasm a b o undary , and a p lanar magnetic axis. Previous ideal m agne tohyd ro ­ dynam ic (M H D ) stability com puta t ions o f freeb o u n d a ry m odes with low values o f the toroidal m ode n u m b e r n show that a...

Planelet Transform: A New Geometrical Wavelet for Compression of Kinect-like Depth Images

With the advent of cheap indoor RGB-D sensors, proper representation of piecewise planar depth images is crucial toward an effective compression method. Although there exist geometrical wavelets for optimal representation of piecewise constant and piecewise linear images (i.e. wedgelets and platelets), an adaptation to piecewise linear fractional functions which correspond to depth variation ov...

Shear-induced configurations of confined colloidal suspensions.

We show that geometric confinement dramatically affects the shear-induced configurations of dense monodisperse colloidal suspensions; a new structure emerges, where layers of particles buckle to stack in a more efficient packing. The volume fraction in the shear zone is controlled by a balance between the viscous stresses and the osmotic pressure of a contacting reservoir of unsheared particles...
