Possibilities of value analysis utilization by selection of mortgage lender
Pískatá, Petra ; Korytárová, Jana (referee) ; Puchýř, Bohumil (advisor)
The aim of this master’s thesis is to find the best type of mortgage loan for several kinds of borrowers. The first part describes personal housing financing, use of loans, use of mortgages in general. At the end of this theoretical part the value analysis is explained as a tool for mortgage lender (or the type of mortgage loan) selection and the way of reaching this goal is defined. Second part is a practical example of how to make decision and find the best choice. It selects the most important criteria and real cash flow is simulated to asset the price of each possibility. Using the discrimination method and efficiency rate the possibilities are ranked. Results are commented on and recommendations are set to every type of client. In conclusion, general method for selection before getting a mortgage is proposed.

Partial Discharges Detection and Spatial Localization in High Power Transformers Using UHF Method
Čáp, Martin ; Král, Bohumil (referee) ; Zemánek,, Ivan (referee) ; Drexler, Petr (advisor)
The thesis discusses the design and experimental verification of a new method for detecting partial discharges in oil-cooled high-power transformers, emphasizing the origin of the measured signal from the outer and inner regions of the transformer tank. The detection and spatial localization of partial discharges utilizes UHF (Ultra High Frequency) electromagnetic signal measurement. The UHF partial discharge detection method, also referred as UHF PD, is one of the most advanced techniques for the accurate spatial localization of the signal source position. The focus of the thesis lies in the development of technical and software solutions for the separation of partial discharge signals originating from the internal space of the transformer and the spurious signals from the connection lines. The proposed technical and program solutions constitute a signal discriminatory method. The precise and repeatable diagnostics of the transformer state are guaranteed by observing the measurement methodology and special setting of the diagnostic system. The functionality of the signal discriminatory method was verified during real measurement of the oil-cooled power transformers at the Dukovany nuclear power plant in operation. The output of the designed methodology is to set up a calibration procedure and follow-up steps to ensure objective, repeatable, and comparable measurements for the purposes of regular predictive maintenance in transformers.
