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.

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.

Design of electric tackle
Bádr, Miroslav ; Kašpárek, Jaroslav (referee) ; Škopán, Miroslav (advisor)
Purposes work was create technical documentation to an electrically driven tackle with actuated by hand undercarriage. Was booked up fundamental parameters like bearing, stroke and hoisting speed. First was effected calculation of load on pinion necks and an idle pulley. Subsequently was effected calculation for right election of a rope, an idle pulley, a rope drum and bearings for the rope drum. Up this calculation followed calculation for a right election of an electric motor and a shaft clutch. The documentation was complemented with pictures and tablets, that are seted near single decisive knots of the tackle. To the documentation was creationed how a suggested arrangement drawing so single subassemblies drawings.
