DEVELOPMENT OF A REFERENCE METHOD FOR THE ABSOLUTE MEASURING OF FLUORESCENCE IN BIOLOGICAL ANALYSIS
… the calibration samples and calculation of their uncertainty budget ,expressed in number of molecules of fluorescein, (NF). The final work goal was to obtain an uncertainty budget for measurements, expressed in equivalent number of molecules of fluorescein (MESF) for each used instrument.. By …

The Development of High Accuracy Methods for the Measurement of Metal Speciation
… pg g’^ (coverage factor, K = 2). Details of the uncertainty budget formulated are also presented. Extract storage for 6 months resulted in a reduction in the MeHg mass fraction by 14-16 %. compared to the original MeHg levels. Both ssIDMS and species-unspecific isotope dilution mass spectrometry …

Application of the optimal estimation method (OEM) to retrieve relative humidity from Raman Lidar backscatter measurements.
… the traditional method the OEM provides a full uncertainty budget with both random and systematic uncertainties on profile by profile basis. The OEM is also capable of retrieving RH from the Raman lidar measurements in different sky conditions and the OEM retrieved RH agree the radiosonde …

Precision Metrology with Ytterbium Ions for New Physics Search
… spectroscopy. We study the systematic uncertainty budget for both types of measurements. We apply the King plot method to isotope shift spectroscopy data and observe the King nonlinearity. Using the analysis of the nonlinearity patterns, we determine the significance of the second …

A Novel Approach to Robust Design Using Recent Advances in Robust and Multiobjective Optimization Methods
… and interesting approaches to the treatment of uncertainty in traditional engineering problems. This paper presents the Budget of Uncertainty (BoU) design method; a new method by which such approaches can be applied in a manner which balances the need for optimization with the desire for robust …

DIRECT VOLTAGE MEASUREMENTS USING BULK ACOUSTIC WAVES IN LiNbO3
… strain effects inputted as a model parameter. An uncertainty budget was carried out for both crystal cuts and compared. Environmental effects such as pressure and temperature were also measured to determine their influence on the sensor under ambient conditions. Published literature regarding …

UNCERTAINTY CONTRIBUTIONS TO SPECIES SPECIFIC ISOTOPE DILUTION ANALYSIS
… statistically different, within the limits of uncertainty, from the certified values. An uncertainty budget for both IDMS procedures has been formulated to allow the performance of each method to be compared For single IDMS the major uncertainty contribution was derived from the within …

Investigation and development of a novel metrology standard for the measurement of relative intensity noise and frequency chirp of DFB lasers in optical networks
… RIN measurement performed, reducing measurement uncertainty associated with rf miss-match, system linearity and loss. High specification components have been assessed individually and in the combined system indicating overall system noise figure of 2 to 3dB over the 10MHz to 20GHz frequency range …
