Study of harmonics detection based on parametric spectral estimation method

open access: yesGong-kuang zidonghua, 2016
Three parametric spectral estimation methods including Yule Walker, Burg and Covariance were studied and an improved Covariance method was proposed based on analysis of AR model.

Parametric Estimation and the CIR Model [PDF]

open access: yesProyecciones (Antofagasta), 2017
We study parametric estimation in the Cox-Ingersoll-Ross model and establish the stochastic differential equations for the parameters involved in it.

Robust State-Feedback Control and Convergence Analysis for Uncertain LPV Systems Using State and Parameter Estimation

open access: yesMathematics
This study introduces the design of a state-feedback controller for Linear Parameter Varying (LPV) systems in scenarios where exogenous parameters are not directly accessible, and the state vector is to be estimated.

On Two-Stage Non-Parametric Estimation [PDF]

open access: yesThe Annals of Mathematical Statistics, 1963
Abstract : A two-sample, two-stage non-parametric estimation problem is studied. The parameter phi phi(F, G) under consideration is estimable (i.e., there exists an unbiased estimator which is a function of independent observations from two populations with cumulative distribution functions F(X) and G(Y). (Hence, it is called a two-sample problem.) The

Parametric estimation analysis of compressive stress effects on piezoelectric properties of PZT ceramic

open access: yesJournal of Asian Ceramic Societies
In this study, the frequency and capacitance of piezoelectric materials due to compressive stress were analyzed, and the overall material properties (compliance matrix, piezoelectric charge constant and dielectric constant) of piezoelectric ceramics were

Parametric Estimation of Lévy Processes [PDF]

open access: yes, 2014
The main purpose of this chapter is to present some theoretical aspects of parametric estimation of Lévy processes based on high-frequency sampling, with a focus on infinite activity pure-jump models. Asymptotics for several classes of explicit estimating functions are discussed.

Comparison of terrestrial exospheric hydrogen 3D distributions at solar minimum and maximum using TWINS Lyman-α observations

open access: yesFrontiers in Astronomy and Space Sciences
Remote sensing observations of far-ultraviolet (FUV) emissions have been used to estimate 3D neutral hydrogen (H) density models of the terrestrial exosphere under solar minimum (2008) and solar maximum (2013 and 2015) conditions.

Parametric a Priori-Aided Beamspace Channel Tracking for Terahertz Massive MIMO Systems

open access: yesIEEE Access
Beamspace massive MIMO with a discrete lens array can significantly reduce the number of RF chains in terahertz systems. However, effective beam selection in such systems requires an accurate beamspace channel estimate, which is difficult to obtain under

Assessment of Methods for Determining Vehicle Emission Characteristics

open access: yesEngineering Transactions
This paper presents an analysis of pollutant emissions (carbon monoxide, hydrocarbons, nitrogen oxides, methane, non-methane volatile organic compounds and carbon dioxide) from a passenger car, particularly under real-world driving conditions, to more ...
