Neutrosophic Generalized Rayleigh Distribution with Application [PDF]

open access: yesNeutrosophic Sets and Systems, 2023
In this paper, we consider the neutrosophic generalized Rayleigh distribution (NGRD). Various neutrosophic properties of NGRD are developed and discussed. The developed distribution is specifically more useful to model indeterminate data which are skewed

A Non-Parametric Approach for Survival Analysis of Component-Based Software [PDF]

open access: yesInternational Journal of Mathematical, Engineering and Management Sciences, 2020
Reliability of a software or system is the probability of system to perform its functions adequately for the stated time period under specific environment conditions.

Bounding Surface Model and Parameters Study on Describing the Behavior of Cement-treated Clay with Cementation Degradation [PDF]

open access: yesZhengzhou Daxue xuebao. Gongxue ban, 2021
Based on the concept of modified mean effective stress, the effect of cementitious bonding and the loss of bonding during loading for cement-treated clay were described, in which most of the parameters could be got automatically by program calculation ...

Synthesis of Load and Feeder Models Using Point on Wave Measurement Data

open access: yesIEEE Open Access Journal of Power and Energy, 2021
This paper describes a novel method to synthesize load and feeder models, by estimating the load composition and the load parameters, using instantaneous voltage and current measurements, obtained at the distribution level, from disturbance events.

A Review of Shannon and Differential Entropy Rate Estimation

open access: yesEntropy, 2021
In this paper, we present a review of Shannon and differential entropy rate estimation techniques. Entropy rate, which measures the average information gain from a stochastic process, is a measure of uncertainty and complexity of a stochastic process. We

Profile Maximum Likelihood Estimation of Single-Index Spatial Dynamic Panel Data Model

open access: yesMathematics, 2023
In this paper, the spatial dynamic panel data (SDPD) model is extended to the single-index spatial dynamic panel data (Si-SDPD) model by introducing a nonlinear connection function to reflect the interaction between explanatory variables.

Comparative Study Between Parametric and Non-Parametric Estimation for the Normal Density Function [PDF]

open access: yesThe Egyptian Statistical Journal, 1993
A comparative study between parametric and non-parametric estimation for the probability density function (pdf) is done. The parametric method depends on additional information (or assumptions) about the form of the pdf.
