Dynamics of thin walled composite beams: Analysis of parametric uncertainties
(Elsevier, 2013-05)
This article is concerned with the stochastic dynamic analysis of structures constructed with composite materials. Depending on many aspects (manufacturing process, material uncertainty, boundary conditions, etc.) real ...
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 ...
Análise de sensibilidade de um sistema massa-mola-amortecedor de dois graus de liberdade
(Universidade Tecnológica Federal do ParanáCornelio ProcopioBrasilEngenharia MecânicaUTFPR, 2016-10-24)
This work proposes to introduce the system sensitivity analysis one and two degrees of freedom with uncertainties in the parameters. The parametric uncertainties are usually modeled using a probabilistic approach. Under ...
Parametric and non-parametric probabilistic approaches in the mechanics of thin-walled composite curved beams
(Elsevier, 2015-05)
In this paper we perform a quantification of the uncertainty propagation of the dynamics of slender initially curved structures constructed with fiber reinforced composite materials. Depending on the manufacturing process, ...
Parameter uncertainty in LCA: stochastic sampling under correlation
Purpose At the parameter level, data inaccuracy, data gaps,
and the use of unrepresentative data have been recognized
as sources of uncertainty in life cycle assessment (LCA). In
many LCA uncertainty studies, parameter ...
Systematic uncertainties from halo asphericity in dark matter searches
(Iop Publishing Ltd, 2015)
Incorporation of uncertainty in technical and economic analysis of a feller-buncher
(2018-01-01)
The constant technical and economic analysis of timber harvesting operations is essential and determining, due to the monetary magnitude. Traditionally, these analyses are conducted deterministically, which does not allow ...
Vibrational problems of timber beams with knots considering uncertainties
(Brazilian Society of Mechanical Sciences & Engineering, 2015-12-12)
A stochastic model of the dynamic behavior of sawn timber beams of Argentinean Eucalyptus grandis is herein presented. The aim of this work is to study the influence of the timber knots in the dynamical response of timber ...
Existence of an equilibrium for infinite horizon economies with and without complete information
(Elsevier Science Sa, 2012-08)
This work proves the existence of an equilibrium for an infinite horizon economy where trade takes place sequentially over time. There exist two types of agents: the first correctly anticipates all future contingent ...
