New Exponentiated Exponential- Rayleigh Distribution: Structure and Properties

open access: yesIbn Al-Haitham Journal for Pure and Applied Sciences
In this research, we will introduce a new distribution, which is called the new exponentiated exponential-Rayleigh distribution, which is built by adding the shape parameter to the cumulative function of the exponential-Rayleigh distribution resulting ...

Protoplanet Dynamics in a Shear-Dominated Disk [PDF]

open access: yes, 2006
The velocity dispersion, or eccentricity distribution, of protoplanets interacting with planetesimals is set by a balance between dynamical friction and viscous stirring.

Intensity Fluctuations in Closed and Open Systems

open access: yes, 1996
We consider the intensity pattern, generated by a monochromatic source, in a disordered cavity coupled to the environment. For weak coupling, and when the source frequency is tuned to a resonance, the intensity distribution is close to Porter-Thomas ...

Truncated Rayleigh Pareto Distribution

open access: yesJournal of Physics: Conference Series, 2020
Abstract In this paper, we introduced a new distribution which is the truncated Rayleigh Pareto distribution of a variable, and some useful functions, and some mathematical and statistical properties such as density function, the cumulative distribution function, limit function, reliability function, hazard function, stress - strength ...

Stable Equilibrium Based on L\'evy Statistics: Stochastic Collision Models Approach

open access: yes, 2003
We investigate equilibrium properties of two very different stochastic collision models: (i) the Rayleigh particle and (ii) the driven Maxwell gas. For both models the equilibrium velocity distribution is a L\'evy distribution, the Maxwell distribution ...

Properties and Inference for a New Class of Generalized Rayleigh Distributions with an Application

open access: yesOpen Mathematics, 2019
In the present paper, we introduce a new form of generalized Rayleigh distribution called the Alpha Power generalized Rayleigh (APGR) distribution by following the idea of extension of the distribution families with the Alpha Power transformation.

Non‐Rayleigh Statistics of Ultrasonic Backscattered Echo from Tissues [PDF]

open access: yes, 1994
The envelope of the backscattered signal from tissues can exhibit non‐Rayleigh statistics if the number density of scatterers is small or if the variations in the scattering cross sections are random. The K distribution which has been used extensively in

Thermalization of matter waves in speckle potentials

open access: yes, 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.

Consistency of a Causal Theory of Radiative Reaction with the Optical Theorem [PDF]

open access: yes, 2011
The Abraham-Lorentz-Dirac equation for a point electron, while suffering from runaway solutions and an acausal response to external forces, is compatible with the optical theorem.
