Aspect of reliability in compatibility evaluation of products
Šenkýř, Michal ; Kovář, Miroslav (referee) ; Koška, Petr (advisor)
The diploma thesis deals with stating the aspects of reliability in product compatibility evaluation, namely with stating result uncertainty in product parameters testing and diagnosis which are imperative for introduction of the product to the market. The practical part of the thesis focuses on stating selected uncertainty in warm-water boilers testing, especially in gas fueled boilers with rated thermal input of max. 70 kW.

Accuracy of the determination of liquid viscosity
Zikmund, Ondřej ; Rozsívalová, Zdenka (referee) ; Frk, Martin (advisor)
This master thesis is focused on the rheological properties of liquids, especially on the viscosity and the standard uncertainty. It explains methods of the viscosity measurement and the calibration selected viscometers, the principle of the determination of standard uncertainty by indirect measurement of the viscosity and the density. The main object of this thesis was to create a specialized centre for viscosity measurement and to create a document which could be used by teaching of diagnostics.

Uncertainty of Measurement Estimation of Mean Monthly Flows Values of the Selected Hydrometric Station at the Svitava River Catchment Area
Paseka, Stanislav ; Janál,, Petr (referee) ; Marton, Daniel (advisor)
Currently, a sizes of the time series elements of average monthly flows uncertainty are not taken into account in more detail and it does not know the estimation of their sizes. The above mentioned fact could ultimately affected the design and operation of large open water reservoirs. This bachelor's thesis deals with the uncertainty of measurement estimation of the mean monthly flows which have derived in the measuring profile Prostřední Poříčí in the Křetínka river in the Svitava river basin. Evaluation is done using a measured values of water level stages and a stage-discharge relation curve. The basis for design of uncertainty affected stage-discharge curves and water lavel stages the Monte Carl method is used. The outcome values of random flows are further evaluated using the statistical methods in the form of the statistical characteristics and presented as uncertainties of mean monthly flows.
