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 ...

Characterizations of Lifetime Distributions Using Two Relative Reliability Measures

Journal of Function Spaces, 2022
In this paper, a general characterization property considering two new dynamic relative reliability measures is obtained. The new dynamic relative reliability measures are expressed as the ratio of hazard rates and as the ratio of reversed hazard rates ...

Characterizations of the transmuted inverse Weibull distribution

ANZIAM Journal, 2014
We characterise the transmuted inverse Weibull distribution and compare it to many other generalizations of the two-parameter inverse Weibull distribution using the likelihood ratio test. Explicit expressions are derived for the quantile, moment generating function, entropies, mean deviation and order statistics.

The public agglomeration effect: Urban–rural divisions in government efficiency and political preferences

American Journal of Political Science, EarlyView.
Abstract Why and when do cities vote for the left? The emergence of the urban–rural divide in the United States in the 1930s is inconsistent with canonical theories of cleavages. This paper introduces an explanation: agglomeration effects. The provision of government services is more efficient in urban environments because of nonrivalries, economies of

A new trigonometric-inspired probability distribution: A simulation study and applications in reliability and hydrology

Alexandria Engineering Journal
The importance of statistical distributions in accurately representing real-world scenarios and aiding in educated decision-making is well recognized. Nonetheless, it is also true that the limitations of these distributions can hinder optimal fitting in ...

Parameter Estimation and Data Analysis Using a Novel Extension of Weibull Distribution [PDF]

The Egyptian Statistical Journal
Recently, statistical modeling has become essential for analyzing real-world datasets across various fields. However, classical statistical distributions often lack the flexibility to capture the complexity of observed phenomena accurately.

Bivariate Mixture of Inverse Weibull Distribution: Properties and Estimation

Mathematical Problems in Engineering, 2020
In this study, we construct a mixture of bivariate inverse Weibull distribution. We assumed that the parameters of two marginals have Bernoulli distributions. Several properties of the proposed model are obtained, such as probability marginal density function, probability marginal cumulative function, the product moment, the moment of the two variables

Improving fatigue resistance of translucent 4Y‐PSZ zirconia through glass gradation

European Journal of Oral Sciences, EarlyView.
Abstract To evaluate the effect of graded glass infiltration on the fatigue behavior and mechanical reliability of translucent 4Y‐PSZ zirconia before and after hydrothermal aging, disc‐shaped specimens were fabricated by uniaxial pressing and divided into control and glass‐graded groups (n = 36/group).

Optimal Hedging Strategies in the Low‐Sulphur Bunker Fuel Landscape

European Financial Management, EarlyView.
ABSTRACT The IMO2020 regulation for the green transition in shipping turned the industry into using two compliant bunker fuels: very low‐sulphur fuel oil (VLSFO) and low‐sulphur marine gas oil (LSMGO). VLSFO futures contracts introduced in late 2019 and other energy‐related futures contracts indicate that the VLSFO contracts trading on the Singapore ...

Computer Vision Enables Monitoring and Kinetic Analysis of Structurally Diverse Carbon Monoxide Surrogates

Angewandte Chemie, Volume 138, Issue 29, 13 July 2026.
A non‐contact computer vision method enables monitoring and quantitative comparison of vessel‐specific CO release kinetics from structurally diverse surrogates in two‐chamber COware reactors, revealing that surrogate reactivity scores correlate with carbonylation reaction outcomes.
