Boundary Limitation of Wavenumbers in Taylor-Vortex Flow

, 1998
We report experimental results for a boundary-mediated wavenumber-adjustment mechanism and for a boundary-limited wavenumber-band of Taylor-vortex flow (TVF).

Analysis of leaky-wave antenna based on partially-filled rectangular waveguide

Известия высших учебных заведений России: Радиоэлектроника, 2015
A leaky-wave antenna based on the partially-filled rectangular waveguide with transverse slots is investigated. Using tensor Green’s functions for antenna radiation analysis is suggested.

Wavenumber selection in coupled transport equations [PDF]

Journal of Mathematical Biology, 2017
We study mechanisms for wavenumber selection in a minimal model for run-and-tumble dynamics. We show that nonlinearity in tumbling rates induces the existence of a plethora of traveling- and standing-wave patterns, as well as a subtle selection mechanism for the wavenumbers of spatio-temporally periodic waves.

On the dual cascade in two-dimensional turbulence

, 2002
We study the dual cascade scenario for two-dimensional turbulence driven by a spectrally localized forcing applied over a finite wavenumber range $[k_\min,k_\max]$ (with $k_\min > 0$) such that the respective energy and enstrophy injection rates ...

Depth wavenumber spectral decomposition based on orthogonal matching pursuit and its application in hydrocarbon reservoir prediction

地质科技通报
Objective Conventional seismic attribute analysis in the time domain is based on the conversion from prestack depth migration data to time domain data, which will cause the loss of effective high-frequency information.
