Evaluation and Comparison of Power Quality Changes from Multiple Measured Points
Koštialik, Marek ; Kopička, Marek (referee) ; Paar, Martin (advisor)
This diploma thesis deal with the description of electrical energy quality in low voltage. A test data model is created in the thesis which can automatically evaluate the state of the quality of electric energy in terms of higher harmonic voltages in the MATLAB programming environment. To verify the correct design of the model, two possible views of simulated data are created in the form of tables and graphical dependencies. An user interface is created for more complex control of each model states of the data being considered.

New gel electrolytes
Sumka, Martin ; Jahn, Michal (referee) ; Sedlaříková, Marie (advisor)
This master´s thesis deals with the properties of gel polymer electrolytes, brief characteristics of other types of electrolytes and materials that are used for preparing polymer electrolytes. The thesis explains the use of the gel electrolytes in practice, the current conduction in the electrolytes and the properties of ionic liquids, and flame retardants. This thesis also focuses on methods of measurement of mechanical properties of gel polymer electrolytes. The practical part is focused on preparation of methacrylate gel electrolytes and their modifications with the use of flame retardant - triethyl phosphate (TEP) and ionic liquid - 1-ethyl-3-methylimidazolium bis(trifluoromethanesulfonyl)imide (Emim TFSI). In this part there are evaluations of their potential funcionality (potential window) and specific conductance conductivity using the method LSV (linear sweep voltammetry) and impedance spectroscopy. The practical part also includes a thermal analysis of selected samples by TGA, DTA and EGA methods.

Diagnosis of reinforced concrete buildings with the system of elevated ceilings
Čeřovský, Martin ; Láník, Jaromír (referee) ; Žítt, Petr (advisor)
This thesis is focused on the diagnostics of reinforced concrete frame structures with the used system of elevated ceilings. The first part of the thesis is devoted to the issue of the methods of design and construction of these objects. The following chapter describes selected methods leading to determination of the material characteristics and to the specification of the constructional system. In its conclusion, the thesis deals with the appropriate design of implementation of the preliminary and detailed exploration of the structures with the used system of elevated ceilings.

Real-Time Analysis of Audio Signals
Řezáč, Martin ; Schimmel, Jiří (referee) ; Černocký, Jan (advisor)
The goal of this thesis is creation an application, which can perform real-time fundamental frequency tracking of incoming audio samples. According to detected frequencies, the program generates MIDI messages, which are sent to chosen MIDI device. First, the reader is introduced to the issue of fundamental frequency tracking. The following part describes individual methods, especially the one based on spectral analysis of a tone. A description of used technologies is also a included in this part of this thesis. In the following part, the implementation and testing of application are described including opinions of several musicians about this product. At the end, the whole work is concluded and the possible further development is outlined.

Projektové řízení ve vybrané firmě
ŠARVAIC, Lukáš
The diploma thesis deals with project management in the company TSE Electronics ltd., specifically the analysis of a selected project, which was sampled during 2020 and 2021. In addition to email communication, the author uses the knowledge from the company's senior employees and the information acquired by the author during normal work activities. In the literature part, attention is paid to project management, project and also the quality management system in the automotive industry, as the selected company primarily focuses on production for this industry, which has certain rules and standards. In the practical part, readers are introduced to the selected company, its organizational structure and the current project management guidelines. It also includes an overview of the current difficult situation in the automotive supply chain in connection with the covid-19 pandemic. Furthermore, the project management in the production of samples is described and evaluated. The project is now successfully introduced into series production. Last but not least, the author proposes several changes for the company that could lead to process optimization and improvement.
