Bayesian Estimation of Component Reliability in Coherent Systems

open access: yesIEEE Access, 2018
The first step in statistical reliability studies of coherent systems is the estimation of the reliability of each system component. For the cases of parallel and series systems, the literature is abundant, but it seems that the present paper is the ...

Adaptive non-parametric estimation in the presence of dependence [PDF]

open access: yes, 2016
We consider non-parametric estimation problems in the presence of dependent data, notably non-parametric regression with random design and non-parametric density estimation. The proposed estimation procedure is based on a dimension reduction. The minimax

Top Incomes and Inequality Measurement: A Comparative Analysis of Correction Methods Using the EU SILC Data

open access: yesEconometrics, 2018
It is sometimes observed and frequently assumed that top incomes in household surveys worldwide are poorly measured and that this problem biases the measurement of income inequality.

A 6DoF Pose Estimation Dataset and Network for Multiple Parametric Shapes in Stacked Scenarios

open access: yesMachines, 2021
Most industrial parts are instantiated from different parametric templates. The 6DoF (6D) pose estimation tasks are challenging, since some part objects from a known template may be unseen before.

Parameter Estimation for a Class of Lifetime Models

open access: yesAbstract and Applied Analysis, 2014
Our purpose in this paper is to present a better method of parametric estimation for a bivariate nonlinear regression model, which takes the performance indicator of rubber aging as the dependent variable and time and temperature as the independent ...

Time-Varying Nonlinear Causality Detection Using Regularized Orthogonal Least Squares and Multi-Wavelets With Applications to EEG

open access: yesIEEE Access, 2018
A new transient Granger causality detection method is proposed based on a time-varying parametric modeling framework, and is applied to the real EEG signals to reveal the causal information flow during motor imagery (MI) tasks.

An Unstructured Model for Anaerobic Treatment of Raw Cheese Whey for Volatile Fatty Acids Production

open access: yesEnergies, 2020
The whey is a byproduct of the dairy industry that, if not treated properly, can cause serious environmental pollution problems. Anaerobic treatment is an alternative for its recovery, since, in addition to reducing the organic load.

Performance Analysis of Matrix Pencil Method Applied to High-Resolution Measurement of Supraharmonics

open access: yesEnergies, 2023
Supraharmonics emitted by power electronic equipment will cause electromagnetic interference. However, there is no uniform standard for the measurement of supraharmonics.

The response of exospheric neutral hydrogen to weak geomagnetic disturbances between June 12 and 29, 2008

open access: yesFrontiers in Astronomy and Space Sciences
Stereoscopic remote sensing observations of terrestrial far ultraviolet (Lyman-α at 121.6 nm) emissions at solar minimum have been used to retrieve the time-dependent response of the exospheric 3-D neutral hydrogen (H) density at radial distances of 3–6 ...
