Utilização do método da amostragem para propagação de incertezas de parâmetros físicos em sistemas com material físsil
(Universidade Federal de Minas GeraisUFMG, 2015-10-28)
There is an uncertainty for all the components that comprise the model of a nuclear system. Assessing the impact of uncertainties in the simulation of fissionable material systems is essential for a realistic calculation ...
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 ...
Error propagation in open respirometric assays
(Brazilian Society of Chemical Engineering, 2014-04)
This work deals with the calculation of the uncertainty of the exogenous respiration rate (Rex) and the total oxygen consumed (OCT) derived from a single open respirometric profile. Uncertainties were evaluated by applying ...
USE OF MONTE CARLO SIMULATIONS FOR THE CALCULATION OF THE UNCERTAINTY ESTIMATE IN THE ELECTROCHEMICAL DETECTION OF URIC ACID IN PLASMA SAMPLES
(Tche Quimica Group, 2018-01-01)
This work presents a low cost, simple and adequately reliable electrochemical alternative for the determination of uric acid in human serum in comparison to the enzymatic colorimetric reference method. The quality of the ...
RAM analysis of dynamic positioning system: An approach taking into account uncertainties and criticality equipment ratings
(2021-01-01)
Currently, a Dynamic Position (DP) System is commonly used for offshore operations. However, DP failures may generate environmental and economic losses; thus, this paper presents the Reliability, Availability and Maintainability ...
