Thermalization of matter waves in speckle potentials

, 2015
We show that the momentum distribution of a nonlinear matter wave suddenly released with a finite velocity in a speckle potential converges, after an out-of-equilibrium evolution, to a universal Rayleigh-Jeans thermal distribution.

Unconditionally secure quantum key-distribution with relatively strong signal pulse [PDF]

, 2007
We propose an unconditionally secure quantum key distribution (QKD) protocol, which uses a relatively strong signal pulse. While our protocol shares similar security bases as the Bennett 1992 protocol with a strong reference pulse (B92), our scheme uses ...

Comparing HARPS and Kepler surveys: The alignment of multiple-planet systems

, 2012
Aims. We study a subset of the planetary population characterized both by HARPS and Kepler surveys. We compare the statistical properties of planets in systems with m.sin i >5-10 M_Earth and R>2 R_Earth.

Large scale cosmic-ray anisotropy with KASCADE

, 2003
The results of an analysis of the large scale anisotropy of cosmic rays in the PeV range are presented. The Rayleigh formalism is applied to the right ascension distribution of extensive air showers measured by the KASCADE experiment.The data set ...

The Slashed‐Rayleigh Fading Channel Distribution

Mathematical Problems in Engineering, 2019
We propose an alternative distribution for modelling fading‐shadowing wireless channels. This distribution presents certain advantages over the Rayleigh‐lognormal distribution and the K distribution and has proved useful in the setting described. We obtain closed‐form expressions for the average channel capacity and for the average bit error rate of ...

Scale Mixture of Rayleigh Distribution [PDF]

Mathematics, 2020
In this paper, the scale mixture of Rayleigh (SMR) distribution is introduced. It is proven that this new model, initially defined as the quotient of two independent random variables, can be expressed as a scale mixture of a Rayleigh and a particular Generalized Gamma distribution.

Intensity distribution for waves in disordered media: deviations from Rayleigh statistics

, 1998
We study the intensity distribution function, P(I), for monochromatic waves propagating in quasi one-dimensional disordered medium, assuming that a point source and a point detector are embedded in the bulk of the medium.

The Albedo Distribution of Near Earth Asteroids [PDF]

, 2016
The cryogenic WISE mission in 2010 was extremely sensitive to asteroids and not biased against detecting dark objects. The albedos of 428 Near Earth Asteroids (NEAs) observed by WISE during its fully cryogenic mission can be fit quite well by a 3 ...

EXPONENTIATED WEIBULL INVERSE RAYLEIGH DISTRIBUTION

, 2023
This work focuses on the study of a new four-parameter Exponentiated Weibull Inverse Rayleigh Distribution (EWIR) using Exponentiated Weibull-G family of distribution as the generator. Statistical properties of the distribution (like, Moment, Quantile, Skewness & Kurtosis, Moment, (Mgf) were derived along with its asymptotic behaviour.

Dynamics and Statistics of Reorientations of Large-Scale Circulation in Turbulent Rotating Rayleigh-B\'{e}nard Convection

, 2019
We present a direct numerical simulation to investigate the dynamics and statistics of reorientations of large-scale circulation (LSC) in turbulent rotating Rayleigh-B\'{e}nard convection (RRBC) for air ($Pr=0.7$) contained in a cylindrical cell with ...
