Economic Evaluation of Acquisition Project
Nechvátal, Marek ; Klíma, Jaroslav (referee) ; Režňáková, Mária (advisor)
The diploma thesis focuses on the economic evaluation of the company acquisition project using methods of discounted cash flow, net present value and discounted payback period. The theoretical part of the thesis uses comprehensive view on modern methods of strategic and financial analysis, financial planning strategy and investment decision-making methods. The second half of the work contains practical part of strategic and financial analysis, calculated cost of equity, weighted average cost of capital and economic evaluation of the acquisition project itself.

Line start synchronous machine
Kaczmarczyk, Ruben ; Mach, Martin (referee) ; Klíma, Jiří (advisor)
This work deals with explanation of the construction of a line start synchronous machine. Furthermore, the calculation of the asynchronous machine is made on the basis of the production documentation. The analytical calculation is done in the RMxprt program, then the calculations of both methods are compared. In addition, rotor adjustment of the specified asynchronous motor is performed, including the insertion of permanent magnets into the rotor. Ansys Maxwell program then optimizes and analyzes the engine, and also checks engine's start-up. Finally, the results are compared and summarized.

Analysis of high-speed induction motor
Klíma, Jiří ; Ondrůšek, Čestmír (referee) ; Vítek, Ondřej (advisor)
This thesis deals with the problem of the high-speed induction machines. In the introduction the design of the machines and problem areas are discussed. The feeding from the frequency converter and the mechanical strength of the rotor appear to be the biggest problem. High-speed engines with solid rotors were designed. The first model is equipped with a conductive cooper layer on the surface. This model is exposed to harmonic and non-harmonic input voltage and then the results of the simulations are compared. The following model of the thesis is equipped with axial slots. In the practical part of the thesis no load measurement is taken. One point was measured at nominal frequency. At the end of the thesis the results of the measurements are compared with the results of the figures extracted from Maxwell software.

Determination of the temperature reactivity coefficient for Nuclear power plant Dukovany
Klíma, Jakub ; Bajgl, Josef (referee) ; Raček, Jiří (advisor)
This thesis deals with the re-determination of the temperature reactivity coefficient of the Nuclear power plant Dukovany, which is measured within the physical test Reheating of the cooling to 260 °C. This paper contains description of the types of nuclear reactors launching, list of tests which are performed during these startings and it also describes methods for determination of temperature reactivity coefficient. Last part of this thesis includes description of programme which was created for determining temperature reactivity coefficient from given files and verification of its calculating methods by statistical test.

An Application with HAWK Controller
Klíma, Jaroslav ; Štohl, Radek (referee) ; Jirgl, Miroslav (advisor)
The target of this bachelor’s thesis is to execute a connection between the HAWK controller by the Centraline/Honeywell company and crane models through the MODBUS/TCP communication protocol, including a demonstration of its functionality and creating a visualisation. Programmable machines SIEMENS S7-1200 were used to control the models. The first part of the thesis is dedicated to describing the HAWK controller and its communication options in its basic configuration. The second part is dedicated to the most utilized functions and terminology of the COACHAX development environment thanks to which the MODBUS communication is executed and a demonstration application is created. The practical part first offers a basic exercise to demonstrate the communication of a programmable machine and the HAWK controller through MODBUS/TCP and then an application which creates a shell system surface, unlike the programmable machines, and offers advanced options of controlling the model and formation of basic functional statistics.

An induction machine with solid rotor
Fišer, Jan ; Klíma, Jiří (referee) ; Mach, Martin (advisor)
This master’s thesis is focused on induction motor with solid rotor. The introduction is dedicated to the full analysis of the rotor. Then model of motor with solid rotor was designed in 2D and 3D. Simulations of these models were carried out using the finite elements method. Further in this thesis there are laboratory measurements` results due to the motor`s sample. Based on the results from simulations and measurements rotor modifications have been proposed, which led to improved machine parameters. 2D models have been developed by rotor modifications. These models went through finite elements method`s simulation. In the conclusion of the thesis there are all results from measurements and simulations compared.
