Analysis of the acoustic signal to detect the speed of vehicles
Koníčková, Tereza ; Beneš, Petr (referee) ; Klusáček, Stanislav (advisor)
The aim of this Bachelor thesis is to create software for sound signal analysis of a passing car with the aim to determine the driving speed. This work describes single methods of a car velocity measurement and it is submitting a new method of velocity measurement with using the Doppler principle at sound signal analysis. My work proved, that it is possible to use this method to determine the speed of vehicles.

Electric and Hybrid Vehicles Analysis
Slaběňák, Patrik ; Kuchyňková, Hana (referee) ; Hájek, Vítězslav (advisor)
Nowadays, oil resources start to decrease, therefore it is necessary to think about alternative sources of energy. The result of this semester project is a basic overview of the current development of electric and hybrid cars, with potential application in normal operation and the proximity of their main characteristics, such as mileage, price and service when traveling. The energy required to operate the electric stored in batteries are recharged using the power stations, which is also devoted part of the work. The thesis focuses on the design and calculation of power consumption for a defined route of four-wheel electric wheelchair. The conclusion of the thesis deals with the future development of hybrid and electric vehicles, and with the expected trends in the field of power electronics and motors and with the propagation of hybrid vehicles to the customers.

The Gallery of Brno Grand Prix
Sikora, Zbigniew ; Boleslavská, Yvona (referee) ; Žalmanová, Petra (advisor)
The main task of this thesis was to create an architectural study of The Gallery of Brno Grand Prix based on previous urban study from previous semester works. The proposal is focused on the iconic circuit’s former glory restoration, on providing new content for raceway complex and creating decent and presentable place for the presentation of the rich history of Czech and Czechoslovak motorsport. The result is a study of an object that meets these needs while respecting the historical and morphological values of the place. The building creates new themed attraction and creates the potential for further development of near circuit.

The engine unit of forestry harvestor
Petr, Tomáš ; Škopán, Miroslav (referee) ; Kašpárek, Jaroslav (advisor)
At the beginning of bachelor´s thesis is description of harvester and its main parts. Then research of four six – wheeled forestry harvesters was developed. Features of compared harvesters are similar to the task. The next point was theoretical part with equations needed for calculation of rolling and inertial resistances. Based on the theory an enumeration of powers of particular driving modes was done. Then performances for work devices of harvester were calculated. From the single values were determined total powers of machine, which were transparently organized into table and graph. Based on the maximal total power were chosen three appropriate engines. From the three was selected the most suitable one.

Aircraft windshield blowing: solution and design possibilities
Šamša, Petr ; Fišer, Jan (referee) ; Jícha, Miroslav (advisor)
My thesis is considering with aircraft windshield blowing for airplanes designed according to CS-23 regulation. The first part introduces the size of precipitation clearing area in connection with CS-23 regulation and report SAE AIR805C. Next chapter describes a few possible design solutions which can be potentially used for windshield precipitation. There are also other methods analysed in that part. There are not only the casual systems like windshield wipers but some more rare or new technologies too. It can be some fluid repellent surfaces or blowers in that category. The third part deals with jet blast system in detail. There will be a design calculation for airflow conditions which are important for the correct function. The last quarter of this thesis mentions the experiment what should compare the theoretical computations from the third part with the real values.

Electronic stability systems
Musil, Jan ; Ambróz, Richard (referee) ; Zháňal, Lubor (advisor)
In this Bachelor’s thesis there are basic electronic stability systems described. These systems are mostly used as a precaution in safety of the traffic, but also to ensure comfort of the crew. The main part of the thesis is focused on systems ABS, ASR and ESP. The other parts aim to describe additional systems, which are still in development. In the end there is also view of various individual car companies and possible steps in the future.

Analysis of traction drive for full electric vehicle
Matela, Petr ; Marušinec, Jaromír (referee) ; Solař, Martin (advisor)
The subject of my bachelor´s thesis is research and computations of the dynamics of different types of engines. The first part of it is devoted to theoretical introduction to electromobilism and electro mobiles history. The rest is about benefits and problems of electro mobiles, their current state and available energy sources. In the conclusion of this thesis there are all necessary calculations and the dynamics of three different engine types is solved and compared.

Realization of educational problem based on experimental apparatus with cam mechanism
Tomeček, Vojtěch ; Vrbka, Martin (referee) ; Vaverka, Michal (advisor)
Bachelor's thesis is focused on solving educational problem based on experimental apparatus with cam mechanism. The task of the educational problem is to teach students to analyse kinematic quantities of cam followers. The thesis contains general discourse on the topic of cam mechanisms and basic terms definition. This is followed by putting the device into service, eliminating its particular imperfections, analysis of kinematic quantities of various combinations of available cams and followers and definition of methodics of the educational problem. The educational problem itself follows the presentation and commentary of gained results. At last some recommendations for the future modifications of the experimental apparatus are given followed by foreshadow of its eventual future usage.

Measurement of gas flow rates
Hniličková, Veronika ; Charvát, Pavel (referee) ; Štětina, Josef (advisor)
This bachelors thesis is about options in a gas volume measurement, it's division and engineering solution of selected types of a gas volume indicators. A thesis is about analysis of measurement methods too. Finally I compare a gas volume measuring indicators, it's usage and functionality in working practicles.
