An objective Bayesian method for including parameter uncertainty in ensemble model output statistics

Quarterly Journal of the Royal Meteorological Society, EarlyView.
Conventional model output statistics and ensemble model output statistics methods for calibrating ensemble forecasts lead to severe underestimation of the probabilities of ensemble extremes (in blue). This is because they ignore statistical parameter uncertainty.

Alpha power inverse Weibull distribution with reliability application

Journal of Taibah University for Science, 2019
In this paper, we use the method of the alpha power transformation to introduce a new generalized alpha power inverse Weibull (APIW) distribution. Its characterization and statistical properties are obtained, such as reliability, moments, entropy and ...

Multi‐level fatigue reliability assessment of reinforced concrete railway bridges

Structural Concrete, EarlyView.
Abstract This paper presents a multi‐level reliability framework for assessing the fatigue life of reinforced concrete (RC) railway trough bridges subjected to cyclic loading. The framework incorporates increasing levels of analytical complexity and real‐world data in four steps. First, an analytical model applies S–N curves and the Palmgren–Miner rule

The Breakdown and Self‐Clearing Performance During the Energy Harvesting Process of Dielectric Elastomer Generators Using Single‐Walled Carbon Nanotubes Electrodes

High Voltage, EarlyView.
ABSTRACT For dielectric elastomer generators (DEG), electrical breakdown is the main failure mode during their working cycle. The application of self‐clearing electrodes is of great significance to avoid a single breakdown leading to the failure of the entire generator.

Inverse Odd Weibull Generated Family of Distribution

Pakistan Journal of Statistics and Operation Research, 2020
This work proposes an inverse odd Weibull (IOW) family of distributions for a lifetime distributions. Some mathematical properties of this family of distribution were derived. Survival, hazard, quantiles, reversed hazard, cumulative, odd functions, kurtosis, skewness, order statistics and entropies of this new family of distribution were examined.

Dielectric Breakdown Characteristics of Biaxially Oriented Polypropylene Films: Surface Structures on Thickness Dependence

High Voltage, EarlyView.
ABSTRACT Film capacitors, essential for energy storage in power systems, benefit from reduced film thickness to increase capacitance and lower costs. While the inverse power law traditionally links higher electric strength with thinner films, its validity diminishes below a critical thickness.

Time to Breakdown for Type I Motor Winding Insulation Under High‐Frequency High‐Slew‐Rate Square Wave Voltages

High Voltage, EarlyView.
ABSTRACT The emergence of (ultra)wide bandgap ((U)WBG)‐based devices has significantly enhanced performance in high‐frequency switching applications, enabling breakthroughs in electric transportation, aerospace, and renewable energy systems. However, it also presents considerable challenges to insulation systems, such as electric motor winding ...
