Efficient Estimation of the Density and Cumulative Distribution Function of the Generalized Rayleigh Distribution

The uniformly minimum variance unbiased (UMVU), maximum likelihood, percentile (PC), least squares (LS) and weighted least squares (WLS) estimators of the probability density function (pdf) and cumulative distribution function are derived for the generalized Rayleigh distribution. This model can be used quite effectively in modelling strength data and also modeling general lifetime data. It has...

Density Distribution Function from H

The cross-section of sky occupied by a particular neutral hydrogen column density (NHI) provides insight into the nature of Lyα absorption systems. We have measured this column density distribution at z=0 using 21-cm Hi emission from a blind survey. A subsample of HI Parkes All Sky Survey (HIPASS) galaxies have been imaged with the Australia Telescope Compact Array (ATCA). The contribution of l...

Reorientation of elongated particles at density interfaces.

Density interfaces in the water column are ubiquitously found in oceans and lakes. Interaction of settling particles with pycnoclines plays a pivotal function in nutrient transport between ocean layers and settling rates of marine particles. We perform direct numerical simulations of an elongated particle settling through a density interface and scrutinize the role of stratification on the sett...

Density Distribution Function at z = 0 from H

We have measured the column density distribution function, f(NHI), at z = 0 using 21-cm Hi emission from galaxies selected from a blind Hi survey. f(NHI) is found to be smaller and flatter at z = 0 than indicated by high-redshift measurements of Damped Lyman-α (DLA) systems, consistent with the predictions of hierarchical galaxy formation. The derived DLA number density per unit redshift, dNDLA...
