Fitting test of two-parameter BS fatigue life distribution and approximate interval estimation of environmental factor

open access: yes上海师范大学学报. 自然科学版, 2019
Two-parameter Birnbaum-Saunders (BS) fatigue life distribution is an important failure model in the probability physical methods.It is more suitable for describing the life rules of fatigue failure products than common life distributions such as Weibull ...

Port-Estimation of a Shape Second-Order Parameter

open access: yesRevstat Statistical Journal, 2014
In this paper we study, under a semi-parametric framework and for heavy right tails, a class of location invariant estimators of a shape second-order parameter, ruling the rate of convergence of the normalised sequence of maximum values to a non ...

A Joint Optimization Algorithm Based on the Optimal Shape Parameter–Gaussian Radial Basis Function Surrogate Model and Its Application

open access: yesMathematics, 2023
We propose a joint optimization algorithm that combines the optimal shape parameter–Gaussian radial basis function (G-RBF) surrogate model with global and local optimization techniques to improve accuracy and reduce costs.

Curvature based characterization of radial basis functions: application to interpolation

open access: yesMathematical Modelling and Analysis, 2023
Choosing the scale or shape parameter of radial basis functions (RBFs) is a well-documented but still an open problem in kernel-based methods. It is common to tune it according to the applications, and it plays a crucial role both for the accuracy and ...

Explaining the Flood Behavior for the Bridge Collapse Sites

open access: yesJournal of Marine Science and Engineering, 2022
Given the increasing intensity and frequency of flood events, and the casualties and cost associated with bridge collapse events, explaining the flood behavior for the collapse sites would be of great necessity.

On the maximum likelihood estimator in the generalized beta regression model [PDF]

open access: yesOpuscula Mathematica, 2012
The subject of this article is to present the beta - regression model, where we assume that one parameter in the model is described as a combination of algebraically independent continuous functions.

Deconstructing Approximate Offsets [PDF]

open access: yes, 2011
We consider the offset-deconstruction problem: Given a polygonal shape Q with n vertices, can it be expressed, up to a tolerance \eps in Hausdorff distance, as the Minkowski sum of another polygonal shape P with a disk of fixed radius?
