Документ Approach to the measurement uncertainty evaluation of the mass concentration phoshorus – containing substances in the sunflower oil(Національний технічний університет "Харківський політехнічний інститут", 2023) Chunikhina, Tetiana; Papchenko, VictoriіaДокумент Measurement uncertainty evaluation by kurtosis method at calibration of a household water meter(2020) Zakharov, Igor; Serhiienko, Maryna; Chunikhina, TetianaThe investigation of measurement uncertainty evaluation at water meter calibration was considered. The peculiarities of this problem is non-linear measurement model and the significant uncertainty, related with the poor repeatability at the small number of the measurements, which makes it difficult to expanded measurement uncertainty evaluate based on the Bayesian approach. The paper checks the influence of the nonlinearity of the model equation on the accuracy of evaluation the numerical value and the standard uncertainty of the measurand. The application of the kurtosis method in the evaluation of the expanded uncertainty of type B and the application of the law of propagation of the expanded uncertainty in the evaluation of the expanded uncertainty of the measurand are described. The obtained values of the expanded uncertainty are very close to the one obtained from Monte Carlo method.Документ Measurment procedure for metrological verification of the measuring channels of the automated process control system for monitoring the turbine generator parameters (СТК-ЕР-М)(Technical University of Sofia Publishing House, 2023) Bossilkov, Krassimir; Tsvetelin, Georgiev; Nikolova, Elena; Radulova, Maya; Chunikhina, TetianaThe report presents the methods for metrological verification of the measuring channels of the automated process control system for monitoring of the turbine generator parameters at Units 5 and 6 at of Kozloduy NPP.Документ Metrology assurance of the temperature measuring channels(Національний технічний університет "Харківський політехнічний інститут", 2024) Banev, Kiril; Chunikhina, TetianaДокумент The measurement uncertainty analysis of the oil concentration in the sunflower seed(2019) Zakharov, Igor; Chunikhina, Tetiana; Papchenko, VictoriіaThe results of the quality research of the new line sunflower seed are presented. The five quality parameters of the sunflower seed were investigated by implementation of the physical and chemical methods. The measurements of the check parameters at the reference conditions were done, the additional errors were absent. The example of the measurement uncertainty analysis of the oil concentration in the sunflower seed was given.
