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.

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 ...

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.

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 ...

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

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 ...

Modelling the Rayleigh match [PDF]
Visual Neuroscience, 2004 We use the photopigment template of Baylor et al. (1987) to define the set of Rayleigh matches that would be satisfied by a photopigment having a given wavelength of peak sensitivity (λmax) and a given optical density (OD). For an observer with two photopigments in the region of the Rayleigh primaries, the observer's unique match is defined by the ...

On the causality of the Rayleigh wave [PDF]
Journal of Mechanics of Materials and Structures, 2016 An explicit hyperbolic-elliptic formulation for surface Rayleigh waves is analysed with an emphasis on the causality of obtained results. As an example, a 3D moving load problem for a distributed vertical load is considered. A simple approximate solution is derived for a near-resonant regime, and the related point load solution is recast as a limiting ...

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
