Design mechanism for raising the roof of a trailer
Štefek, Ondřej ; Zeizinger, Lukáš (referee) ; Foltýnová, Dana (advisor)
This bachelor's thesis deals with the design of a mechanism for lifting the roof of a flatbed trailer. Commercially available mechanical and hydraulic lifts are described in the introduction. In the next chapters, the design of mechanical and hydraulic lifts is discussed. For selected structural elements of mechanical lifting, a safety analysis is then performed with respect to the limit state of elasticity and ergonomic control. For hydraulic lifting, the safety of the cylinder rod for buckling is checked. The proposals are then financially calculated and compared with commercially available lifts. Drawing documentation is prepared for mechanical lifting.

Improvement in the System Quality of Toll’s Withdrawal in The Czech Republic
Marek, Jiří ; Orlíková, Radka (referee) ; Bartes, František (advisor)
The subject of this thesis “Improvement in the system quality of toll’s withdrawal in The Czech Republic” is to look into the problems of toll’s electronic withdrawal. The First part of the thesis describes the taxation quotas on the basis of a microwave technology, relevant legislative, troll’s outcomes, and work of the Czech Customs Administration as a control body and contains an evaluation of the electronic troll system with its advantages and disadvantages. The Second part states theoretical solutions as the EU legislative, which states a traffic policy strategy and a tax withdrawal for using the roads. Further on, it analyses the options of the troll’s electronic withdrawal on the basis of a microwave and satellite system in particular countries. The Third part focuses on its own solutions, which aim is to increase the users’ comfort while using this system. The Fourth part focuses on the benefits of the ideas for solutions stated in the part Three.

Evaluation design of civil airports effectivity indices
Novotný, Roman ; Janík, Radomír (referee) ; Veselý, Petr (advisor)
Introductory part of this thesis concludes the development of air traffic, division of airports in the Czech Republic according to the Ministry of Transport, according to the Law on Civil Aviation and according to the Coding of the airports (Requirement L 14). The aim was to realize theoretical definition and division of output and economic indicators. After that comes choice of appropriate airports from the European Union. The choice has been made on the basis of the number of check-in passengers at the airport in Prague-Ruzyně. Eight most suitable airports have been chosen from all twenty-seven member countries of the EU. The following step is comparative analysis of these chosen airports on the basis of specified output and economic indicators for the years 2005-2009. The year 2010 has not been included, because the chosen airports did not complete their annual reports, balances and statements of profit and loss. From these sources the values for calculation of individual indicators have been chosen. These indicators have been shown in charts, evaluated by means of graphs in Excel Programme and further they have been characterized in words. The aim of the thesis was also the evaluation and comparison of output and economic indicators of effectiveness and after evaluation, proposal of methods of evaluations has followed.
