NON EQUILIBRIUM DENSITY PROFILES IN LORENTZ TUBES WITH THERMOSTATED BOUNDARIES
EQUILIBRIUM DENSITY PROFILES THERMOSTATED BOUNDARIES
2015/9/29
We consider a long Lorentz tube with absorbing boundaries.
Particles are injected to the tube from the left end. We compute the equilibrium density pro les in two cases: the semi-in nite tube (in whi...
Electon density profiles of the topside ionosphere
ionograms electron density profiles satellite orbits altitude
2015/9/25
The existing uncertainties about the electron density profiles in the topside ionosphere, i.e., in the height region from h m F 2 to ~ 2000 km, require the search for new data sources. The ISIS and Al...
Ionospheric topside models compared with experimental electron density profiles
topside ionosphere electron density models topside soundings
2015/9/10
Recently an increasing number of topside electron density profiles has been made available to the scientific community
on the Internet. These data are important for ionospheric modeling purposes, sin...
Comparison of analytical functions used to describe topside electron density profiles with satellite data
topside ionosphere ionospheric modeling ionospheric layer formulation top side soundings
2015/9/10
Electron density models of the ionosphere use different analytical formulations for the electron density vertical
profile in the topside. The present paper compares some single-layer topside analytic...
On the origin of cold dark matter halo density profiles
dark matter large-scale structure of the universe
2014/12/24
N-body simulations predict that cold dark matter (CDM) halo-assembly occurs in two phases: (i) a fast-accretion phase with a rapidly deepening potential well; and (ii) a slow-accretion phase character...
The role of the initial surface density profiles of the disc on giant planet formation: comparing with observations
the initial surface density profiles the disc on giant planet formation
2011/1/10
In order to explain the main characteristics of the observed population of extrasolar planets and the giant planets in the Solar System, we need to get a clear understanding of which are the initial c...
Galaxy clustering and projected density profiles as traced by satellites in photometric surveys: Methodology and luminosity dependence
Galaxy clustering projected density profiles photometric surveys
2010/11/12
We develop a new method which measures the projected density distribution wp(rp)n of photometric galaxies surrounding a set of spectroscopically-identified galaxies, and simultaneously the projected c...

DARK MATTER HALOES：AN ADDITIONAL CRITERION FOR THE CHOICE OF FITTING DENSITY PROFILES
cosmology dark matter
2009/3/5
Simulated dark matter haloes are tted by self-similar, universal
density pro les, where the scaled parameters depend only on a scaled (truncation)
radius, = R=r0, which, in turn, is supposed to b...

Linear Approximation Density Profiles Baroclinic Instability
2008/7/11
The linear approximation of density and velocity profiles is compared to more realistic models with vertically inhomogeneous density gradients and nonzero anomalous vorticity (i.e., the nonplanetary p...
