Framework for Analysis and Identification of Nonlinear Distributed Parameter Systems using Bayesian Uncertainty Quantification based on Generalized Polynomial Chaos
In this work, the Uncertainty Quantification (UQ) approaches combined systematically to analyze and identify systems. The generalized Polynomial Chaos (gPC) expansion is applied to reduce the computational effort. The ...
Dynamics of magneto electro elastic curved beams: Quantification of parametric uncertainties
(Elsevier, 2015-12-01)
The objective of this paper is the evaluation of uncertainty propagation associated to several parameters in the dynamics of magneto-electro-elastic (MEE) curved beams. These MEE structures can be employed as imbedded parts ...
Quantification of parametric uncertainties induced by irregular soil loading in orchard tower sprayer nonlinear dynamics
(2017-11-10)
This paper deals with the nonlinear stochastic dynamics of an orchard tower sprayer subjected to random excitations due to soil irregularities. A consistent stochastic model of uncertainties is constructed to describe ...
Uncertainty quantification in the dynamics of a guyed mast subjected to wind load
(Elsevier, 2017-02)
A study of the stochastic dynamics of a guyed mast under wind action is reported in the present work. The simplified structural model consists of a beam-column accounting for the second order effect due to axial loads ...
Damage detection in an uncertain nonlinear beam
(2017-01-01)
The present paper proposes the use of discrete time Volterra series expanded with Kautz filters for predicting the experimental response of a nonlinear beam, taking into account uncertainties that are inherent to the system. ...
Quantification of uncertainties associated with space-time estimates of short-term soil CO2 emissions in a sugar cane area
(2013-03-01)
The characterization of soil CO2 emissions (FCO2) is important for the study of the global carbon cycle. This phenomenon presents great variability in space and time, a characteristic that makes attempts at modeling and ...
Experimental study of the variations in the electromechanical properties of piezoelectric energy harvesters and their impact on the frequency response function
(Academic Press, 2019)
This work presents a comprehensive study of the uncertainties involved in the FrequencyResponse Function (FRF) of Piezoelectric Energy Harvesters (PEHs) based on experimentalresults. A proper experimental setup is designed ...
