Measurement uncertainties determined by the Monte Carlo method
Krejčí, Roman ; Havlíková, Marie (referee) ; Šedivá, Soňa (advisor)
This bachelor thesis deals with the determination of the uncertainties of direct and indirect measurements. It focused on the uncertainty calculation by Monte Carlo method and GUM uncertainty framework. The practical part deals with the determination of uncertainties indirect measurement of resistance Ohm’s method. The calculated uncertainties are compared on the basis of the influence of the method, accuracy used devices and the temperature.

Real-time Control of Ball on Wheel Model
Krejčí, Roman ; Otava, Lukáš (referee) ; Hynčica, Ondřej (advisor)
This diploma thesis deals with control the Ball on the wheel system in real time. In the first part there is made mathematical model of system, which is described by state equations. Then the laboratory model of Ball on the wheel system and its parts are described. The laboratory model consists servo drive, servo amplifier, microcontroller with real-time operating system and distance sensors. In the practical part of the thesis there is designed control of system by linear quadratic regulator and its implementation with control peripherals into microcontroller with real-time operating system. Ball on the wheel system is controlled by microcontroller, which sends a commands to servo amplifier by CAN bus.
