Thermodynamic method for assessing hydraulic machine efficiency
Mizera, Ladislav ; Ševčík, Petr (referee) ; Habán, Vladimír (advisor)
The master´s thesis contained basic information about the method of thermodynamic efficiency of hydraulic machines. The first part briefly mentioned our opinion on the most widely used method for determining the efficiency of hydraulic machines. Another section of thesis is characterization and measurement procedure using the thermodynamic method. Another section describes measurements of water plants and laboratory measurements, which took place in the past. The final part describes the results of laboratory measurements, which took place in the lab of VUT FSI Brno, and evaluating and comparing the results.

Analog Signals Datalogger
Ščišľak, Tomáš ; Frýza, Tomáš (referee) ; Vyskočil, Pavel (advisor)
The subject of my bachelor’s thesis is construction of device, which provides measuring and digitally recording of analog signals. The first part of this thesis deals with an analysis of circuit properties and building the basic scheme. It was important to choose proper components available. Datalogger consists of integrated digital circuits, which provide fast and reliable communication path. Function of main unit performs microcontroller Atmega128. The realization of external modules for current sensing looks interresting, particularly implementation of Hall sensor ACS755, circuits HCPL and solution of their connection with the main board. Second part of this thesis is oriented on hardware and software realization.

Calculations of temperature fields on the model of induction motor
Koníček, Pavel ; Makki, Zbyněk (referee) ; Janda, Marcel (advisor)
The aim of this work is to get acquainted with the construction of induction motor, the calculation of temperature fields in the motor model in ANSYS Workbench and subsequent evaluation of the results for different operating conditions. There is provided a general description of the function and design of induction motor, a summary of sources of heat inside the engine design, heat transfer theory, the basic description of the finite element method and ANSYS Workbench description. Furthermore, comparison of temperatures measured on a real engine with the values obtained from the calculation program.
