Parameter estimation for the weibull general log-linear model in accelerated life testing
(Journal article; Tidsskriftartikkel; Peer reviewed, 2025)Uncertainty is commonly present in accelerated life test (ALT) data. The combination of a general log-linear model with a statistical distribution model—using the Weibull distribution in this paper—allows for addressing both multiple operational factors and uncertainty within a single model. This paper interprets the Weibull General Log-Linear (WGLL) model from the ALT perspective. Two parameter ... -
A Novel Device for Accurate Measurement of Spray Frequency and Duration using Capacitive Liquid Sensors in Marine Icing Estimation
(Journal article; Tidsskriftartikkel; Peer reviewed, 2024-06-16)Spray duration and frequency are essential parameters to consider when estimating ice accretion on marine structures.
