Design of Communication system among Moving Vehicles
Klampár, Marián ; Polívka, Michal (referee) ; Škorpil, Vladislav (advisor)
The purpose of this thesis is to show up possibilities of inter-vehicle communication and to introduce new approaches in communication for the purpose of enhancing the security and the fluency of vehicle transportation. This thesis also highlights vulnerabilities in communication. The main goal is the analysis of existing technology and the design of protocol for data transfer with focus on minimizing handover time of informations. Part of the design is a simulation of communication based on acquired information.

Traffic Doppler Radar
Kulig, Radomír ; Józsa, Ladislav (referee) ; Šebesta, Jiří (advisor)
This work deals with problematics of speed measurement of an object with a Doppler radar. This radar communicates with other environment through RS232 interface. The complete solution of this Doppler radar is provided in the thesis. There are electrical schemes of all parts and program to control microcontroller in this work. Speed measurements for the radar are summarized in the end of the work.

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.

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.

Effect of lubricant rheology on lubrication film thickness.
Prášilová, Alena ; Šperka, Petr (referee) ; Křupka, Ivan (advisor)
Lubrication is a very important part of mechanical engineering, which ensures high lifetime of machine parts, reduction of friction and wear and also it leads to decreasing of power consumption. In this bachelor`s thesis there is described rheology of newtonian and non-newtonian lubricants and its effect on lubrication film thickness. Measured central film thickness values are compared with theoretical prediction.

Local Ventilation
Bilík, Martin ; Otáhal, Jan (referee) ; Krejčí, Vladimír (advisor)
This bachelor thesis deals with local ventilation, especially a variant of the local exhausting. At the start of work shall indicate the reasons why it is ventilation very important. There are listed some requirements for ventilation of technical and legislative terms. Ventilation systems are analyzed by several criteria in the next part. The next chapter of this work is devoted to systems and methods of local ventilation. In one chapter is made and a description of the distribution parts of the ventilation system. The last chapter deals with designing and using exhaust adapters. There is also made comparison of their parameters, which represent the operating costs associated with using these adapters.

Gravital conveyor for transport
Fatka, Milan ; Pokorný, Přemysl (referee) ; Kašpárek, Jaroslav (advisor)
The aim was to propose a conveying gravity path for the transport of steel casting in the context of inter-transfer service. The conveyor is dealt with valid norms with regard to simplicity of design, production and assembly (disassembly) with broad use of standardized parts. It was also seen to be done to take advantage of the proposal in solution of similar specification.
