Analysis of Key Comparisons Incorporating Knowledge About Bias
(2012)
A method is proposed for analyzing key comparison data. It is based on the assumption that each laboratory participating in the comparison exercise obtains independent and consistent estimates of the measurand and that, ...

Correlação de medidas de glicosímetros e dosagem laboratorial
(Universidade Tecnológica Federal do ParanáCuritibaPrograma de Pós-Graduação em Engenharia Biomédica, 2014-07-15)
The glucometer allows the measurement of glycemia to be performed by the user without hindering his daily routine. Two principles are used to measure the level of blood glycemia: photometric and amperometric. On the ...
Assessment of Three Spectroscopic Techniques for Rapid Estimation of Calcite in Copper Ore
(IEEE, 2010)
This paper presents the assessment of three spectroscopic techniques, i.e., Raman spectroscopy (RS), ultraviolet fluorescence (UVF) spectroscopy, and energy-dispersive X-ray diffraction (ED-XRD), for measuring calcite ...
Power standard based on a high precision power-factor meter
(IEEE, 1998)
A high-precision power-factor meter, based on zero crossing detectors, is proposed. The influence of the distortion in the input signals is analyzed and low pass filters proposed to prevent this error source. This system ...
Evaluation of low-frequency voltage dividers, using the step response
(IEEE, 1998)
A method to characterize the behavior of low frequency voltage dividers, based on the step response, is presented. Amplitude errors and phase displacements can be evaluated, in an absolute way, without any auxiliary standard ...
A contribuição de planos de manutenção em um laboratório de instituição de ensino superior pública
(Universidade Federal de Santa MariaBrasilUFSMCentro de Tecnologia, 2017-11-29)
The reliability lack of a measurement system can generate errors that directly influence the activities and decisions of an organization. In some cases, this reliability lack may be linked to problems in procedures or even ...
