The shape of vortices in quasi-geostrophic turbulence

, 2003
Partially supported by the UK EPSRC (Grant GR/N11711)The present work discusses the most commonly occurring shape of the coherent vortical structures in rapidly rotating stably stratified turbulence, under the quasi-geostrophic approximation. In decaying

Coherent polarization shift keying modulated free space optical links over a Gamma-Gamma turbulence channel [PDF]

, 2011
Problem statement: The optical signal propagating through the Free Space Optical (FSO) channel suffers from irradiance and phase fluctuations caused by the atmospheric turbulence, which results in Bit Error Rate (BER) performance degradation ...

Atomized Oxidative Polymerization as a 3D Printing Platform for Binder‐Free, Bulk Conductive Polymer Architectures

Advanced Functional Materials, EarlyView.
Co‐delivery of electrosprayed EDOT and oxidant enables bulk oxidative polymerization during layer‐by‐layer fabrication, creating stable, highly conductive 3D PEDOT structures. This Atomized Oxidative Polymerization (AOP) overcomes the surface deposition‐only and matrix‐limited conductivity of conventional Vapor Phase Polymerization (VPP) and PEDOT:PSS ...

THE POINT OBJECT'S IMAGE FORMING RAY MODEL

Odessa Astronomical Publications, 2017
Light wave front's distortions are commonly explained by atmosphere turbulence. But Anler equation solution's analysis shows that distributed homogeneous medium even in the absence of turbulence makes nonlinear transformation of coordinates as well as ...

The Search for Atmospheric Laminar Channels: Experimental Results and Method Dissemination

Sensors, 2021
In this paper, a practical application of theoretical developments found in our previous works is explored in relation to atmospheric lidar data. Multifractal structures, previously named “laminar channels”, have been identified in atmospheric profiles ...

Profiling the turbulent atmosphere and novel correction techniques for imaging and photometry in astronomy [PDF]

, 2010
The turbulent atmosphere has two detrimental effects in astronomy. The phase aberration induced by the turbulence broaden the point spread function (PSF) and limits the resolution for imaging.
