Confirmation of temperature chamber and determination of measurement uncertainty
Beníšek, Ondřej ; Šindelář, Michal (referee) ; Šedivá, Soňa (advisor)
The master's thesis deals with the confirmation of temperature chambers, with the greatest emphasis on the determination of standard measurement uncertainty, both by the classical method (GUM) and the Monte Carlo method. It includes the design of a measuring system with data transfer to a computer using the USB communication interface and an analysis of the sources of uncertainty entering the system, which are then practically quantified. To obtain the data, a measuring experiment was carried out in the CVVOZE testing laboratory. The LabView program was used for virtual instrumentation, in which a measuring application was designed and created, which takes care of the collection and processing of measured data. The result of the application is, in addition to recording temperatures from all measured points in the chamber, also the standard uncertainty calculated by the GUM and Monte Carlo methods, including plotting a histogram from the results obtained by both methods in order to compare them. Finally, the achieved results are compared and evaluated.

Estimation of standard uncertainty of temperature
Beníšek, Ondřej ; Havránek, Zdeněk (referee) ; Šedivá, Soňa (advisor)
The bachelor thesis deals with determination of uncertainties of direct and indirect measurements by classical method (GUM) and Monte Carlo method. Specifically, it focuses on determining the uncertainty of the entire measuring chain when calibrating temperature sensors. It contains a design of a measurement experiment for calibrating temperature sensors in a calibration device with data transfer to a computer by a communication interface using a measuring instrument. The procedure for determining the uncertainty of the temperature measurement entering the proposed measurement is also given. The thesis also describes the realization of the practical measurement and the calculation of the standard uncertainty for the measurement by the classic method and Monte Carlo method. The results obtained are compared and evaluated.
