Solutions for better fitting Sigmoid-shaped functions to binary data [PDF]

open access: yesComputational Ecology and Software, 2020
Sigmoid-shaped curves are often used to estimate the probability of individuals surviving or becoming fecund (response: y) given some characteristic like age or size (predictor: x).

Temperature dependence of dielectric breakdown of silicone-based dielectric elastomers

open access: yesInternational Journal of Smart and Nano Materials, 2020
A large number of insulation/dielectric failures in power systems are related to thermally-induced dielectrical breakdown, also known as ‘thermal breakdown’, at higher operating temperatures.

Statistical characteristics, probability distribution, and power potential of sea water velocity in Turkey

open access: yesEuropean Mechanical Science, 2022
Sea currents have the potential to supply electricity from a renewable energy source to coastal regions. The assessment of the potential energy that could be generated is the first step toward developing this resource.

Reliability analysis of structural ceramic components using a three-parameter Weibull distribution [PDF]

open access: yes, 1992
Described here are nonlinear regression estimators for the three-Weibull distribution. Issues relating to the bias and invariance associated with these estimators are examined numerically using Monte Carlo simulation methods.

Effect of the stochastic weibull parameters on the reliability of the dialysis machine [PDF]

open access: yesEngineering and Technology Journal
Dialysis machines operate in an uncertain environment with several sources of disturbances; therefore, it is necessary to take account of the uncertainties during all their life phases.

The effect of wall thickness distribution on mechanical reliability and strength in unidirectional porous ceramics

open access: yesScience and Technology of Advanced Materials, 2016
Macroporous ceramics exhibit an intrinsic strength variability caused by the random distribution of defects in their structure. However, the precise role of microstructural features, other than pore volume, on reliability is still unknown.

Finite-Size Effects on Return Interval Distributions for Weakest-Link-Scaling Systems

open access: yes, 2014
The Weibull distribution is a commonly used model for the strength of brittle materials and earthquake return intervals. Deviations from Weibull scaling, however, have been observed in earthquake return intervals and in the fracture strength of quasi ...

q-exponential, Weibull, and q-Weibull distributions: an empirical analysis

open access: yes, 2003
In a comparative study, the q-exponential and Weibull distributions are employed to investigate frequency distributions of basketball baskets, cyclone victims, brand-name drugs by retail sales, and highway length.
