-2 in ...
Political uncertainty and economic underdevelopment
(Universidad de Chile. Facultad de Economía y Negocios, 2001-06)
Political instability has been emphasized as a major source of uncertainty in
Latin America. However, arbitrariness, i.e. the lack of constraints on the government,
can also be seen as a major source of uncertainty in ...
Metodologia de cálculo de incertezas de medição para uma bancada dinamométrica para motores de combustão interna
(Universidade Federal de Santa MariaBrasilUFSMCentro de Tecnologia, 2023-02-16)
Measurement uncertainties are related to experiments and measurement instruments. They quantify the reliability of the experiment, that is, the greater the uncertainty, the lower the reliability of the result. According ...

Uncertainty estimation of anions and cations measured by ion chromatography in fine urban ambient particles (PM 2.5)
(2012)
The present work presents a measurement uncertainty evaluation according to Guide to the Expression of Uncertainty in Measurement (GUM) of the concentration of the cations K + and Li + and anions NO 3 -2 and SO 4 -2 in ...
Quantifying seismic source parameter uncertainties
We use data from a small aperture array in southern California to quantify variations in source parameter estimates at closely spaced stations (distances ranging from ?7 to 350 m) to provide constraints on parameter ...
Estimating the uncertainty in the atmospheric ammonia concentration in an urban area by Ogawa passive samplers
(2013)
Ammonia, one of the ambient gasses that require environmental monitoring, is typically measured using a passive sampling method. The present work presents an evaluation of the uncertainty according to the Guide to the ...
Reactive power support pricing of distributed generators with primary energy source uncertainty
(2011-05-31)
In this paper, a novel methodology to price the reactive power support ancillary service of Distributed Generators (DGs) with primary energy source uncertainty is shown. The proposed methodology provides the service pricing ...
