Rayleigh and Raman Scattering from Alkali Atoms
Two computational methods developed recently [McNamara, Fursa, and Bray, Phys. Rev. A 98, 043435 (2018)] for calculating Rayleigh and Raman scattering cross sections for atomic hydrogen have been extended to quasi one-electron systems.

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

Non-linear enhancement of laser generated ultrasonic Rayleigh waves by cracks [PDF]
Laser generated ultrasound has been widely used for detecting cracks, surface and sub-surface defects in many different materials. It provides a non-contact wideband excitation source which can be focused into different geometries.

Rayleigh-Rayleigh Distribution: Properties and Applications
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 ...

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

Exponentially growing solutions in homogeneous Rayleigh-Benard convection [PDF]
It is shown that homogeneous Rayleigh-Benard flow, i.e., Rayleigh-Benard turbulence with periodic boundary conditions in all directions and a volume forcing of the temperature field by a mean gradient, has a family of exact, exponentially growing ...

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

A new versatile modification of the Rayleigh distribution for modeling COVID-19 mortality rates
The aim of this paper is to specify a new flexible statistical model to analyze COVID-19 mortality rates in Italy and Canada. A new versatile lifetime distribution with four parameters is proposed by using the exponentiated generalized class of ...
