On suitability of modified Weibull extension distribution in modeling product lifetimes and reliability

open access: yesAdvances in Mechanical Engineering, 2022
The Weibull distribution (WD) is an important lifetime model. Due to its prime importance in modeling life data, many researchers have proposed different modifications of WD.

A study on comparisons of Bayesian and classical parameter estimation methods for the two-parameter Weibull distribution

open access: yes, 2020
The main objective of this paper is to determine the best estimators of the shape and scale parameters of the two parameter Weibull distribution. Therefore, both classical and Bayesian approximation methods are considered.

Estimation, Prediction and Life Testing Plan for the Exponentiated Gumbel Type-II Progressive Censored Data

open access: yesRevstat Statistical Journal, 2023
This article accentuates the estimation and prediction of a three-parameter exponentiated Gumbel type-II (EGT-II) distribution when the data are progressively type-II (PT-II) censored.

Estimating the Entropy of a Weibull Distribution under Generalized Progressive Hybrid Censoring

open access: yesEntropy, 2015
Recently, progressive hybrid censoring schemes have become quite popular in a life-testing problem and reliability analysis. However, the limitation of the progressive hybrid censoring scheme is that it cannot be applied when few failures occur before ...

Bayes estimators for the extreme-value reliability function [PDF]

open access: yes, 2006
Bayes estimates under both modified symmetric and asymmetric loss functions are obtained for the reliability function of the extreme value distribution (EV1) using Lindley's approximation procedure.

From the sea to DNA barcode: Optimized preservation method for gelatinous zooplankton integrative taxonomy

open access: yesLimnology and Oceanography: Methods, EarlyView.
Abstract Assigning taxonomic identity and thus assessing taxonomic diversity in gelatinous zooplankton is challenging due to their fragility and difficult preservation. Formalin fixation compromises DNA integrity, while flash‐freezing, ethanol, and acetone preservation affect morphological features. In this study, we developed a methodological protocol

Analysis of Reliability Characteristics of Bathtub-Shaped Distribution Under Adaptive Type-I Progressive Hybrid Censoring

open access: yesIEEE Access, 2020
In reliability and life testing experiments, obtaining complete data still consumes lots of time, financial and human supports. A censoring scheme which can have balance between the total testing time, the used number of units and cost in life tests is ...

Guapira leucophylla (Nyctaginaceae, Caryophyllales), a new species from the northern Espinhaço Range of Minas Gerais, Brazil

open access: yesNordic Journal of Botany, EarlyView.
Guapira Aubl. (Nyctaginaceae, Pisonieae) comprises dioecious shrubs and trees widely distributed in the Neotropics and occupying diverse habitats. In the Brazilian Cerrado, the genus occurs in several phytophysiognomies, including Campos Rupestres, a montane rock ecosystem with high levels of endemism but still marked by significant gaps in botanical ...
