The Weibull-Gamma Distribution: Properties and Applications

open access: yesEntropy, 2019
A new member of the Weibull-generated (Weibull-G) family of distributions—namely the Weibull-gamma distribution—is proposed. This four-parameter distribution can provide great flexibility in modeling different data distribution shapes.

Comparison Of Three Numerical Methods For Estimating Weibull Parameters Using Weibull Distribution Model In Nigeria [PDF]

open access: yes, 2020
There is a crucial need in Nigeria to enhance the development of wind technology in order to boost our energy supply. Adequate knowledge about the wind speed distribution becomes very essential in the establishment of Wind Energy Conversion Systems (WECS)

Weibull parameters evaluation by different methods for windmills farms

open access: yesEnergy Reports, 2020
Electrical power generated from the wind’s motion is one of the most common clean and renewable energy produced. The wind turbines used to convert wind mechanical power to electricity have to be placed at a site presenting favorable conditions. This work

Analysis of Weibull parameters for wind power generation

open access: yesProcceedings of the 24th ABCM International Congress of Mechanicl Engineering, 2017
The aim of the present work is to perform an analysis of both Weibull parameters k and c for wind power generation so that one can have an idea of how the mechanisms of wind energy estimation work and build a better understanding of these parameters.

The Least Square and the Weighted Least Square Methods for Estimating the Weibull Distribution Parameters - A Comparative Study

open access: yes, 2012
In this paper we study the performance of the least square method and the weighted least square method for estimating the Weibull distribution parameters. In engineering practice these methods are commonly used due to their simplicity.

Relativistic Landau resonances [PDF]

open access: yes, 2005
The possible interactions between plasma waves and relativistic charged particles are considered. An electromagnetic perturbation in the plasma is formulated as an elliptically polarized wave, and the collisionless plasma is described by a distribution ...

Integrated modeling of the sports and reliability data: Implications of the probabilistic model and deep learning approaches

open access: yesAlexandria Engineering Journal
In this paper, we consider the evolution of a new probability distribution called the exponential flexible Weibull distribution. The proposed exponential flexible Weibull distribution is obtained by combining the flexible Weibull extension with the ...

Evaluation of three methods for estimating the Weibull distribution parameters of Chinese pine (Pinus tabulaeformis )

open access: yesJournal of Forest Science, 2008
Weibull distribution was used to fit tree diameter data collected from 86 sample plots located in Chinese pine stand in Beijing. To estimate the Weibull distribution parameters, three methods [namely maximum likelihood estimation method (MLE), method of ...
