Duality and Non-linear Response for Quantum Hall Systems [PDF]
, 2001 We derive the implications of particle-vortex duality for the electromagnetic response of Quantum Hall systems beyond the linear-response regime. This provides a first theoretical explanation of the remarkable duality which has been observed in the ...

Micro-Ramps for Hypersonic Flow Control
Micromachines, 2012 Shock/boundary layer interaction (SBLI) is an undesirable phenomenon, occurring in high-speed propulsion systems. The conventional method to manipulate and control SBLI is using a bleed system that involves the removal of a certain amount of mass of the ...

High resolution computation of the aerodynamics and acoustics of blade vortex interaction [PDF]
, 2008 In the present work, high resolution CFD simulations have been performed on an idealised problem of the interaction of an independently generated vortex with a rotor blade, including a case where the vortex directly impacts on the blade.
