Enhancing Wind Energy Potential Assessment with Three-Parameter Weibull Distribution: A Comparative Analysis using MATLAB [PDF]

open access: yesE3S Web of Conferences
To determine the wind energy potential, the probability density function is typically used. For data distribution with modest wind speeds, this paper developed a three-parameter Weibull model.

A covariance-based test for shared frailty in multivariate lifetime data [PDF]

open access: yes, 2012
We decompose the score statistic for testing for shared finite variance frailty in multivariate lifetime data into marginal and covariance-based terms.

Evaluation of the performance of five distribution functions for estimating Weibull parameters for wind energy potential in Nigeria

open access: yesScientific African
Wind energy is one of the most sought after worldwide among renewable energy sources. In order to determine the wind potential of a particular site, the wind speed has to be characterized and the Weibull parameters accurately determined. Characterization

Weibull S-N Fatigue Strength Curve Analysis for A572 Gr. 50 Steel, Based on the True Stress—True Strain Approach

open access: yesApplied Sciences, 2020
In this paper a Weibull methodology to determine the probabilistic percentiles for the S-N curve of the A572 Gr. 50 steel is formulated. The given Weibull/S-N formulation is based on the true stress and true strain values, which are both determined from ...

A modified truncated distribution for modeling the heavy tail, engineering and environmental sciences data.

open access: yesPLoS ONE, 2021
Truncated models are imperative to efficiently analyze the finite data that we observe in almost all the real life situations. In this paper, a new truncated distribution having four parameters named Weibull-Truncated Exponential Distribution (W-TEXPD ...
