Experimental evaluation of cylinder vortex shedding noise reduction using porous material
Experiments in Fluids, 2020 The tonal noise generation of a circular cylinder in a uniform flow is an important source of aerodynamic noise. It can be found at parts of the landing gear of airplanes, at pantographs of trains, at antennas and basically all other protruding parts of ...

Reduced frequency noise in superconducting resonators [PDF]
, 2010 We report a reduction of the frequency noise in coplanar waveguide superconducting resonators. The reduction of 7 dB is achieved by removing the exposed dielectric substrate surface from the region with high electric fields and by using NbTiN. In a model-

Numerical investigation of a feed-forward linewidth reduction scheme using a mode-locked laser model of reduced complexity [PDF]
, 2018 We provide numerical verification of a feed-forward, heterodyne-based phase noise reduction scheme using single-sideband modulation that obviates the need for optical filtering at the output.
