Synthesis Weibull Stochastic Differential Equation: Properties and application

Scientific African
The Weibull distribution is suitable for modeling stochastic phenomena. However, most of the existing stochastic differential equations (SDEs) of Weibull type found in the literature do not follow the Weibull distribution, making them unsuitable for ...

The Dual Exponentiated Weibull Model [PDF]

Journal of Mathematics and Statistics, 2019
A new lifetime model with various shapes of the hazard rate function for modeling uni-modal and bimodal data sets is introduced and studied along with its statistical properties. Before using the maximum likelihood method for estimating the unknown model parameters, we assessed its performance via a simulation study. The flexibility of the new model is

Pulsed Light Technology in Food Safety and Preservation: Principles, Applications, and Future Directions

Food Chemistry International, EarlyView.
Pulsed light technology uses short high‐intensity broad‐spectrum flashes (200–1100 nm) to inactivate microbes via DNA damage. It preserves food quality, extends shelf life, and works on liquids, meats, and produce, often combined with other hurdles for enhanced efficacy.

Postharvest Survival of Foodborne Pathogens on Strawberry Surfaces at Different Maturity Levels

Food Safety and Health, EarlyView.
This study highlights the survival of E. coli and L. monocytogenes on strawberries at different maturity stages and storage temperatures. Predictive microbial modeling revealed temperature‐ and ripeness‐dependent survival trends, emphasizing the importance of temperature control and ripeness in developing effective strategies to enhance strawberry ...

Risk Forecasting in Shipping Exchange‐Traded‐Fund (ETF) Markets

International Journal of Finance &Economics, EarlyView.
ABSTRACT This article examines the risk properties of freight‐derivative‐based exchange‐traded funds (ETFs), focusing on the Breakwave Dry Bulk Shipping ETF (BDRY), and evaluates the accuracy of Value‐at‐Risk (VaR) and Expected Shortfall (ES) forecasts across a range of econometric models.

A Bi-Level Weibull Model with Applications to Two Ordered Events

International Journal of Prognostics and Health Management, 2017
In this paper, we propose and study a new bivariate Weibull model, called Bi-levelWeibullModel, which arises when one failure occurs after the other. Under some specific regularity conditions, the reliability function of the second event can be above the

Intergenerational transmission of anxiety: A comparison of transdiagnostic and disorder‐specific pathways

JCPP Advances, EarlyView.
Abstract Background Individuals with a parental history of anxiety disorders are at risk of developing an anxiety disorder. Prior studies have focused on the transmission of specific anxiety disorders across generations (i.e., disorder‐specific transmission), often overlooking the possibility that a general tendency to develop various forms of anxiety ...

Generalization of Log-Logistic Family with Quantile Regression Model

Mathematical and Computational Applications
A new general class of distributions is proposed by applying the transformation to the random variable that follows the generalized odd-logistic family. Using the proposed family, we introduce a flexible Weibull distribution.

Spatial and Temporal Patterns of Extreme Hourly Rainfall in the Hawaiian Islands

International Journal of Climatology, EarlyView.
The extreme rainfall trends in Hawaiʻi were revealed by hourly rainfall data: Across islands, Kauaʻi and Hawaiʻi Island had larger events at a return period. Annual maximum series of 15 gauges showed significant positive trends. While extreme rainfall trends show increases or decreases regionally, the trends varied with rainfall duration.
