Desing and implementation of the LCC converter application for emulation validating of the integrated LLC converters
Pokorný, Ondřej ; Levek, Vladimír (referee) ; Prokop, Roman (advisor)
This bachelor’s thesis deals with the design of an LLC converter, which will be used for the verification of prototypes of integrated circuit designs, as well as its applications. First, we address why we chose the LLC converter specifically for this application. We continue by analysing the specific type of converter and describe its function. The main point of this thesis is the numerical design with input parameters, which concludes with a simulation which verifies the calculated values. The product of the thesis is the design of the final wiring diagram of the LLC converter and the test board (module) and their realisation on PCB. The thesis concludes with a verification of the whole construction using a test board in a practical measurement. The work includes the author’s own design of a transformer, as well as a discussion on the problematics of the usage of magnetic circuits for LLC converters.

The Optimal Accuracy of Measurement Assurance in Accordance with Metrological Confirmation
Frank, Petr ; Kocman, Karel (referee) ; Nenadál, Jaroslav (referee) ; Hruška, Karel (advisor)
This thesis deals with the evaluation of accuracy of measurement and achieving the required accuracy level. This includes global analysis of the uncertainty evaluation, the calibration interval design and the creation of confirmation system. Basis of this work is in identification of all possible problems, which may occur during evaluation of accuracy and achieving the required accuracy level. The analysis is followed by suggested solutions for identified problems. It means namely the selection of probability distribution in case of uncertainty type A, evaluation of degrees of freedom in case of uncertainty type B, nonlinear correlation of input values, evaluation of coverage factor, the choice of method for calibration interval design and the procedure for meeting all metrological confirmation requirements. The last part of the thesis is practical measurement and result evaluation in the field of surge protection devices. This chapter demonstrates conclusions from the syntactical part.

Audit of Assets of the Selected Company
Pernica, Ivo ; Sehnalová, Lucie (referee) ; Křížová, Zuzana (advisor)
The thesis is focused on the audit of the financial statements especially to the part of assets. The theoretical part describes the general characteristics of the audit, specifies selected areas of financial statement audit and defines accounting issues of fixed assets and inventory. The second part describes application process of auditing activities in a field of assets in a particular company. From the identified deficiencies are suggested recommendations which are focused to inventory valuation and depreciation of fixed assets.

Perspektivy rozvoje elektricky poháněných vozidel kategorie M
BRABEC, Martin
The number of cars with the combustion engines which they move on the roads all around the world is alarming. It is impossible to overlook the incidental impacts of this expansion out of consideration for this number. The most perceptible impact is on our environment where we live. The air, especially in the cities, is not what it once was. Alternative-fuel vehicles start to be used because of these impacts and we believe in improvement. One of the solutions is using electric vehicles (EV). The request of this thesis is: The perspectives of the electric vehicles' development of category M. The main goal of this thesis was the determination of the factors which have some effect on the development of electromobility. Afterwards it was important to do the practical verification of chosen electric vehicles (EV) on the same road and the evaluation of the figures gained during the measuring. The other operation factors were also verified with these problems.

Postmodern Characteristics of KURT VONNEGUT
Adamová, Kateřina ; Klumparová, Štěpánka (advisor) ; Kubíček, Tomáš (referee)
This thesis analyzes narrative strategies of Kurt Vonnegut as a postmodern author with a specific style. The first part defines postmodernism as opposed to modernism and explains all essential notions to provide the theoretical background. This part also includes a biographical element, describing the important events of the author's life, as these had a major influence on his work. Second part of the thesis analyzes the narrative style of the two selected books, Breakfast of Champions and Mother Night. The conclusion summarizes the most important specifics of the author's narrative strategies and style in the given books. This thesis presents Kurt Vonnegut as a significant and influential representative of postmodern American literature of the second half of the 20th century. Vonnegut fully employs the narrative strategies typical for this period, and by experimenting he creates his own unique style.
