Rayleigh Mixture Distribution [PDF]

Journal of Applied Mathematics, 2011
This paper presents Rayleigh mixtures of distributions in which the weight functions are assumed to be chi‐square, t and F sampling distributions. The exact probability density functions of the mixture of two correlated Rayleigh random variables have been derived.

Rayleigh-Rayleigh Distribution: Properties and Applications

Journal of Physics: Conference Series, 2020
Abstract In this paper, a new compound distribution named Rayleigh-Rayleigh (Ra-Ra) is presented. Several structural statistical properties of new distribution containing explicit expressions for the r-th moments, characteristic function, quantile function, order statistics, Shannon and relative entropies, besides stress strength ...

Non-Rayleigh scattering behavior for anisotropic Rayleigh particles [PDF]

Optics Letters, 2012
Derived from the light scattering by a radially anisotropic sphere, unusual scattering behavior is exhibited, which breaks the Rayleigh law (scattering efficiency Q(sca)~q(4) as q→0, where q is the size parameter). Under certain conditions, we demonstrate an asymptotical relation between Q(sca) and q, i.e., Q(sca)=Fq(8), which is not realizable for ...

ON PSEUDO-RAYLEIGH DISTRIBUTION

Far East Journal of Theoretical Statistics, 2021
Summary: Analyzing the performance and evaluating the reliability of multicomponent system in various fields of engineering and technology follow bivariate pseudo-Rayleigh distributions. In this work, we have discussed a new bivariate pseudo-Rayleigh distribution. Some standard properties of distribution have been studied.

Bit Error Rate Closed-Form Expressions for LoRa Systems under Nakagami and Rice Fading Channels

Sensors, 2019
We derive exact closed-form expressions for Long Range (LoRa) bit error probability and diversity order for channels subject to Nakagami-m, Rayleigh and Rician fading.

Prandtl and Rayleigh numbers dependences in Rayleigh-Bénard convection [PDF]

Europhysics Letters (EPL), 2002
Using low-temperature gaseous helium close to the critical point, we investigate the Prandtl-number dependence of the effective heat conductivity (Nusselt number) for a 1/2 aspect ratio Rayleigh-Benard cell. Very weak dependence is observed in the range 0.7 < Pr < 21; 2 × 108 < Ra < 2 × 1010: the absolute value of the average logarithmic slope δ = (∂ln

Enhancing Wind Energy Potential Assessment with Three-Parameter Weibull Distribution: A Comparative Analysis using MATLAB [PDF]

E3S Web of Conferences
To determine the wind energy potential, the probability density function is typically used. For data distribution with modest wind speeds, this paper developed a three-parameter Weibull model.

Rayleigh and Prandtl number scaling in the bulk of Rayleigh–Bénard turbulence [PDF]

Physics of Fluids, 2005
The Ra and Pr number scaling of the Nusselt number Nu, the Reynolds number Re, the temperature fluctuations, and the kinetic and thermal dissipation rates is studied for (numerical) homogeneous Rayleigh–Bénard turbulence, i.e., Rayleigh–Bénard turbulence with periodic boundary conditions in all directions and a volume forcing of the temperature field ...

Sine Half-Logistic Inverse Rayleigh Distribution: Properties, Estimation, and Applications in Biomedical Data

Journal of Mathematics, 2021
A new lifetime distribution with two parameters, known as the sine half-logistic inverse Rayleigh distribution, is proposed and studied as an extension of the half-logistic inverse Rayleigh model.

On Rayleigh's Principle [PDF]

Geophysical Journal International, 1976
Summary In the theory of the Earth's normal modes of oscillation it is customary to use Rayleigh's principle in the determination of perturbations in the eigenperiods due to perturbations in the structure of an Earth model. When internal boundaries are perturbed the usual methods have been found to yield incorrect numerical results and this paper is
