Noise in the interior of vehicles and methods of reducing it
Patočka, Pavel ; Zajac, Roman (referee) ; Otipka, Václav (advisor)
The bachelor thesis focuses on the issues of noise in the interior of vehicles and the methods of subsequent decrease of such noise. Moreover, the thesis shortly describes the most notable sources of noise involved in the overall acoustic within the automobile. The undertaken analysis illustrates that the main source of noise in older vehicles is the combustion engine, an exhaust and intake system, and a gearbox tool. Conversely in modern vehicles, as a result of the unceasing progress of alternative drives, the most notable noise in modern vehicles is the aerodynamic noise and the noise forming out of the contact between tires and roadway. The research showcases that the elimination of these sources is aimed at the use of isolation and absorption structures, as well as the technologically advanced methods such as the ANC method. In relation to the increasing pressure on emission-free traffic, often resulting in insufficient vehicle soundproofing, the thesis summarises the findings concerning the issues of additional vehicle soundproofing.

Design of wireless headphones.
Zdvyhal, Milan ; Zvonek, Miroslav (referee) ; Křenek, Ladislav (advisor)
The topic of my bachelor’s thesis is to design an innovative solution of wireless headphones with a consideration to certain timelessness, trends and modern technologies. The purpose is to create thing, which will be unconventive and will respect technological processes and ergonomical parametres with main focus on maximal comfort and simply control.

Postavení ekologických zemědělských podniků v podmínkách ČR
Vošmerová, Denisa
This thesis is about the position of organic farms in the Czech Republic's conditions. The results are compared with conventional farms. Sets of surveyed farms are classified into three categories due to the region where they are farming (mountain ANC, other ANC, and areas outside of ANC). This thesis aimed to answer the questions which arose from literature research. These questions are written in the chapter Aim of the thesis. At-tention was paid to agricultural production and financial indicators. And also, the subsi-dies and their effect on the farm's economic situation had attention. It was evaluated by the share of an operating subsidies on net added value. The net added value was also used to calculate the farm's economic viability. In the end, there is environmental strain caused by farming which was also evaluated. Based on a comparison of selected costs. As a main database was used Farm Accountancy Data Network (FADN). One of the main findings is differences in the intensity of agricultural production. In terms of different types of farming (organic and conventional) and also in terms of ANC. The composition of agricultural production was also considered. Animal production is more in ANC com-pared to crop production which is more in areas outside of ANC. And also, the farm's dependency on operating subsidies was confirmed. While organic farms are more de-pendent on these subsidies than conventional farms. Due to the characteristics of organic farming, the expected results of environmental strain were confirmed. Organic farming caused lower environmental strain than conventional farms.

Tuzarová, Zdeňka ; Žárová, Marcela (advisor) ; Černý, Václav (referee)
This submitted thesis deals with the regulation of accounting in France. The goal of this thesis is to introduce the French accounting from the regulation point of view. The first part of the thesis focuses on factors which influence the regulation of French accounting. It's followed by institutions that can create new accounting norms, where the most important one is ANC, or that can at least influence the regulation. After that, the thesis introduces also the French law valid for this field. The second part of the thesis contains certain accounting principles and methods in order to explain how the French accounting is regulated from the point of current accounting. The third part is focused on accounting reporting, there is also a short analysis of balance sheet and profit and loss statement of an anonymous French company. Finally the thesis is focused on the profession of certified accountant and auditor, their authorities and role in the French accounting system.
