A Fabry-Perot like interferometer with two microwaveguide adaptors as reflectors creates a passive dielectric medium with a negative group delay time due to polarization shift. A rotational strain of ...
Validity of Viscous Core Correction Models for Self-Induced Velocity Calculations
Validity of Viscous Core Correction Models Self-Induced Velocity Calculations Computational Physics
2012/4/20
Viscous core correction models are used in free wake simulations to remove the infinite velocities at the vortex centreline. It will be shown that the assumption that these corrections converge to the...

Cosmology observations (Cosmology:) dark matter Galaxies clusters
2011/1/5
We present relations between X-ray luminosity and velocity dispersion (L − ), X-ray luminosity and gas mass (L − Mgas), and cluster radius and velocity dispersion (r500 − ) for 62 ...
Large enhancement in hole velocity and mobility in p-type [110] and [111] silicon nanowires by cross section scaling: An atomistic analysis
silicon nanowire mobility p-type holes atomistic bandstructure
2010/11/22
The mobility of p-type nanowires (NWs) of diameters of D=12nm down to D=3nm, in [100], [110], and [111] transport orientations is calculated. An atomistic tightbinding model is used to calculate the N...

Distinguished hyperbolic trajectories in time-dependent fluid flows:analytical and computational approach for velocity fields defined as data sets
Distinguished hyperbolic trajectories time-dependent fluid flows velocity fields
2009/11/12
In this paper we develop analytical and numerical methods for finding special hyperbolic trajectories that govern geometry of Lagrangian structures in time-dependent vector fields. The vector fields (...
We show that certain types of quantum walks can be modeled as waves that propagate in a medium with phase and group velocities that are explicitly calculable. Since the group and phase velocities indi...
