Penetrative convection in stratified fluids:velocity and temperature measurements
Penetrative convection stratified fluids velocity and temperature measurements
2009/11/9
The flux through the interface between a mixing layer and a stable layer plays a fundamental role in characterizing and forecasting the quality of water in stratified lakes and in the oceans, and the ...
Dispersion and collapse in stochastic velocity fields on a cylinder
Turbulence Lagrangian trajectories Kraichnan ensemble Cylindrical manifolds
2010/4/7
The dynamics of fluid particles on cylindrical manifolds is investigated. The velocity field is obtained by generalizing the isotropic Kraichnan ensemble, and is therefore Gaussian and decorrelated in...
Investigating turbulent structure of ionospheric plasma velocity using the Halley SuperDARN radar
turbulent structure ionospheric plasma velocity Halley SuperDARN radar
2009/11/3
We present a detailed analysis of the spatial structure of the ionospheric plasma velocity in the nightside F-region ionosphere, poleward of the open-closed magnetic field line boundary (OCB), i.e. in...
Scaling properties of velocity and temperature spectra above the surface friction layer in a convective atmospheric boundary layer
properties of velocity temperature spectra surface friction layer atmospheric boundary layer
2009/11/3
We report velocity and temperature spectra measured at nine levels from 1.42 meters up to 25.7 m over a smooth playa in Western Utah. Data are from highly convective conditions when the magnitude of t...
Dispersion of Pollutants in Semi-Infinite Porous Media with Unsteady Velocity Distribution
Dispersion of Pollutants Semi-Infinite Porous Media Unsteady Velocity Distribution
2009/10/28
Analytical solutions are developed for the dispersion problem in nonadsorbing
and adsorbing, semi-infinite porous media in which the flow is one
dimensional and the average flow velocity is unsteady...
Simulation Technique of Velocity-Based Discrete-time Control System with Intelligent Control Concepts for Open Architectural Industrial Robots
Simulation Technique Architectural Industrial Robots Velocity-Based Discrete-time Control System
2009/9/25
Industrial robots have drastically rationalized many kinds of manufacturing processes in industrial fields. For this decade, open architectural industrial robots have been produced from several indust...
MEASUREMENT OF THE LICK INDICES IN EARLY-TYPE GALAXIES: LINE-OF-SIGHT VELOCITY DISTRIBUTION CORRECTIONS FOR IC 1459
Line: profiles Methods: data analysis Galaxies: elliptical and lenticular, cD Galaxies: kinematics and dynamics Galaxies: individual (IC 1459)
2010/10/29
In this paper we analyse the measurements of the absorption line-strength Lick indices in the early-type galaxy IC 1459. We use the long-slit spectra of the elliptical galaxy IC 1459 from which its ki...
A comparative analysis of two wind velocity retrieval techniques by using a single Doppler radar
Velocity Azimuth Display Atmospheric Boundary Layer Atmospheric Boundary Layer
2009/7/22
This study compares the theoretical basis of the two wind velocity retrieval methods, Velocity Azimuth Display (VAD) and Velocity Area Display (VARD) by using data obtained by a single Doppler radar. ...
