Inverse Unit Teissier Distribution: Theory and Practical Examples

open access: yesAxioms, 2023
In this paper, we emphasize a new one-parameter distribution with support as [1,+∞). It is constructed from the inverse method applied to an understudied one-parameter unit distribution, the unit Teissier distribution.

New Distribution for Fitting Discrete Data: The Poisson-Gold Distribution and Its Statistical Properties

open access: yesAustrian Journal of Statistics, 2021
Motivated mainly by lifetime issues, a new lifetime distribution coined ``Discrete Poisson-Gold distribution'' is introduced in this paper. Different structural properties of the new distribution are derived including moment generating function and the ...

Modelling travel time distribution and its influence over stochastic vehicle scheduling

open access: yesTransport, 2019
Due to the paucity of well-established modelling approaches or well-accepted travel time distributions, the existing travel time models are often assumed to follow certain popular distributions, such as normal or lognormal, which may lead to results ...

A Statistical Method for Estimating Activity Uncertainty Parameters to Improve Project Forecasting

open access: yesEntropy, 2019
Just like any physical system, projects have entropy that must be managed by spending energy. The entropy is the project’s tendency to move to a state of disorder (schedule delays, cost overruns), and the energy process is an inherent part of any ...

Fitting Procedure to Reconstruct the Size Distribution and the Concentration of Silver Colloidal Nanoparticles from UV-Vis Spectra

open access: yesNanomaterials, 2022
In this work, a complete fitting procedure of UV-Vis spectra of silver nanoparticles in colloidal solutions is reported. The fitting function, based on the Beer–Lambert law, Mie theory, and log-normal probability distribution of nanoparticles’ sizes, is ...
