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

Linear Stochastic Models of Nonlinear Dynamical Systems

open access: yes, 1998
We investigate in this work the validity of linear stochastic models for nonlinear dynamical systems. We exploit as our basic tool a previously proposed Rayleigh-Ritz approximation for the effective action of nonlinear dynamical systems started from ...

Eigenvalue Dynamics of a Central Wishart Matrix with Application to MIMO Systems [PDF]

open access: yes, 2015
We investigate the dynamic behavior of the stationary random process defined by a central complex Wishart (CW) matrix ${\bf{W}}(t)$ as it varies along a certain dimension $t$.

stochastic model for generalized Rayleigh distribution using three sources

open access: yesInternational journal of health sciences, 2022
Of all Cancers, Oral cancer is one of the most typical cancers in the world. Oral cancer has delayed clinical detection, poor prognosis, without specific biomarkers, and expensive therapeutic methods. This study aims to explain the basic aspects of oral cancers and focuses on squamous cell carcinoma of the oral cavity.

A Quantitative Printability Framework for Programmable Assembly of Pre‐Vascular Patterns via Laser‐Induced Forward Transfer

open access: yesAdvanced Healthcare Materials, EarlyView.
Laser‐Induced Forward Transfer (LIFT) is presented as a powerful micropatterning tool. An objective printability framework is developed to assess optimal printing parameter combinations. The technology is further explored for its ability to deterministically deposit microdroplets at predefined locations following CAD designs, enabling the patterning of

A new probabilistic approach for data modeling in practical scenarios: Considering reliability data with computer knowledge graphs

open access: yesAlexandria Engineering Journal
It is well-established in the existing literature that probability distributions significantly influence data modeling and the representation of real-world situations. In light of the considerable influence that probability distributions exert in various

Moments of generalized order statistics for Pareto-Rayleigh distribution

open access: yesOpen Journal of Mathematical Sciences, 2021
In this paper, we derive the explicit expressions for single and product moments of generalized order statistics from Pareto-Rayleigh distribution using hypergeometric functions. Also, some interesting remarks are presented.
