Exponentiated Weibull–Poisson distribution: Model, properties and applications [PDF]

Mathematics and Computers in Simulation, 2013
In this paper we propose a new four-parameters distribution with increasing, decreasing, bathtub-shaped and unimodal failure rate, called as the exponentiated Weibull-Poisson (EWP) distribution. The new distribution arises on a latent complementary risk problem base and is obtained by compounding exponentiated Weibull (EW) and Poisson distributions ...

A new Weibull Exponentiated Inverted Weibull Distribution for modelling positively-skewed data

, 2021
An Exponentiated Inverted Weibull Distribution (EIWD) has a hazard rate (failure rate) function that is unimodal, thus making it less efficient for modeling data with an increasing failure rate (IFR).

Numerical Exploration of Thermal Shock Resistance in MgO–C Refractories

Advanced Engineering Materials, Volume 28, Issue 10, 20 May 2026.
A mesostructure‐resolved numerical framework is developed to evaluate the thermal shock resistance of MgO–C refractories. By modeling interface debonding under rapid temperature changes and introducing a modified thermal shock parameter that accounts for mesocracks, the study shows how graphite content and aggregate size influence thermal shock ...

Joint Frailty Mixture Cure Model for Recurrent Event Data With Dependent Censoring: An MCEM Approach

Statistics in Medicine, Volume 45, Issue 10-12, May 2026.
ABSTRACT Advancements in modern medical technology have enabled cures for a fraction of patients while extending survival times for those who are not cured. For non‐cured patients, disease recurrence is influenced by observed covariates and unobserved individual heterogeneity (random effects).

Transformed Semicircular Exponentiated Weibull Distribution

Journal of Physics: Conference Series, 2022
Abstract In this paper, a new transformed Semicircular Exponentiated Weibull ( SEW ) distribution of three parameters is constructed by applying the transformation of the inverse stereographic projection that maps a real line to the unit circle.

A Study of Two Parameter Based an Exponential Probability Distribution: Properties and Applications

Engineering Reports, Volume 8, Issue 1, January 2026.
In this article, we introduce a novel two‐parameter survival distribution to offer enhanced flexibility and applicability in statistical modeling. This distribution is characterized by highly adaptable probability density and hazard rate functions. Specifically, the probability density function (PDF) can exhibit unimodal behavior with an inverted shape

Bivariate Exponentiated Modified Weibull Extension Distribution

, 2016
In this paper, a new bivariate exponentiated modified Weibull extension distribution (BEMWE) is introduced. This model is of Marshall-Olkin type. The marginals of the new bivariate distribution have exponentiated modified Weibull extension distribution ...

Statistical Inference for a General Family of Modified Exponentiated Distributions

Mathematics, 2021
In this paper, a modified exponentiated family of distributions is introduced. The new model was built from a continuous parent cumulative distribution function and depends on a shape parameter.

Performance Analysis of the LDPC‐Coded Hybrid LQAM‐MPPM for UWOC Systems

IET Optoelectronics, Volume 20, Issue 1, January/December 2026.
The effectiveness of LDPC codes in improving the performance of hybrid modulations is discussed, with coded 128‐QAM‐(12, 2) MPPM offering ~6.5 and 5.8 dB code gains at a BER of in strong and moderate turbulence, respectively. These results demonstrate the promise of hybrid modulation with LDPC as a robust and efficient modulation scheme for UWOC ...
