Terahertz Channel Modeling, Estimation and Localization in RIS‐Assisted Systems

Advanced Electronic Materials, EarlyView.
Reconfigurable intelligent surfaces have become a recent intensive research focus. Based on practical applications, channel strategies for RIS‐assisted terahertz wireless communication systems are categorized into three different types: channel modeling, channel estimation, and channel localization.

Stochastic frontiers with a Rayleigh distribution

, 2015
We introduce a stochastic frontier model with a one-parameter distribution known as the Rayleigh distribution which has a non-zero mode and yet it is easy to estimate and use. We show how this model can be estimated using various estimation methods.

A method constructing density functions: the case of a generalized Rayleigh variable [PDF]

, 2009
summary:In this paper we propose a new generalized Rayleigh distribution different from that introduced in Apl. Mat. {\it 47} (1976), pp.\,395--412. The construction makes use of the so-called ``conservability approach'' (see Kybernetika {\it 25} (1989),

Efficient Estimation of the Density and Cumulative Distribution Function of the Generalized Rayleigh Distribution [PDF]

Journal of Statistical Research of Iran, 2013
The uniformly minimum variance unbiased (UMVU), maximum likelihood, percentile (PC), least squares (LS) and weighted least squares (WLS) estimators of the probability density function (pdf) and cumulative distribution function are derived for the generalized Rayleigh distribution.

Assessing Mesoscale Heterogeneities in Hard Carbon Electrodes Through Deep Learning‐Assisted FIB‐SEM Characterization, Manufacturing and Electrochemical Modeling

Advanced Energy Materials, EarlyView.
A combination of discrete and finite element method models for the current collector deformation and electrochemical performance analysis, respectively. The models are calibrated and validated with electrochemical and imaging data of hard carbon electrodes. These electrodes were manufactured with different parameters (slurry solid contents of 35 and 40

Recurrence Relations for Moment Generating Functions of the Generalized Compound Rayleigh Distribution [PDF]

, 2023
In this paper, we consider the three-parameter generalized compound Rayleigh distribution. The recurrence relations for moment generating functions based on the generalized order statistics are obtained. The results presented here are a generalization of

Generalized rayleigh principle and its applications

, 1983
In this paper, we mainly deal with cigenvalue problems of non-self-adjoint operator. To begin with, the generalized Rayleigh variational principle, the idea of which was due to Morse and Feshbach, is examined in detail and proved more strictly in ...
