Springing and Damping of Truck Cabin
Kroupa, Ondřej ; Vančura, Jan (referee) ; Blaťák, Ondřej (advisor)
This Diploma Theses, which can be included in the field of vehicle dynamics, explores the effect of suspension and damping of truck cabs for the safe ride and comfort. As the driver spends many hours in their vehicle, comfort is the most essential criterion. That is why we seek possible improvements which are offered by the sprung cab. The research part firstly analyses the individual elements of suspension and damping. The following chapter is devoted to the systems which are used nowadays in the construction of cabin suspension. Next there is the introduction to the theoretical production of a simplified computational model as well as the presentation of the possible evaluation of the achieved results. The following practical part deals with the actual shaping of the computational model in the Adams View software, which is based on a real vehicle, and was lent at the faculty. The model is then verified and compared with the existing state and the cab mounting concepts are tested on it. The effects of cab parameters on driving comfort and safe riding were tested on it as well. The last part focuses on the forming of the special Dakar computational model, on which optimization was performed according to the findings discussed in the previous chapter. Also, the appropriate configurations to the real-life testing were designed.

Technological Process of the Elevator Cab Production
Trojková, Ludmila ; Osička, Karel (referee) ; Kalivoda, Milan (advisor)
The aim of the thesis is to present the topic of the technological process of the elevator cab production. First, the work will deal with the introduction of the product, equipment, machinery and tools for an enterprise and which suppliers they are from. The second part will deal with the existing technological processes of enclosures made of stainless steel or glass. The last part will focus on the economic evaluation and the proposal to increase the efficiency of the production.

Design of agricultural cutting machine
Hráček, Petr ; Chorý, Tomáš (referee) ; Zvonek, Miroslav (advisor)
This diploma thesis should bring not only working machine into the branch of agricultural industry, but also new approach to design. Obviously, the contribution of technical innovations, which are required in this segment, is concerned, too. All knowledge and concepts come from the practise of this field. The project partly takes up the pre-diploma thesis called Vision of the agricultural cutting machine with container arrangement and shares some details of the concept as such. The technical part was solved during the winter term within the scope of the subject Machines and equipment. From this project will be adopted all bases of constructional innovations of agricultural machine concept.

Ergonomie kabiny zemědělských traktorů
Fiala, Lukáš
The bachelor thesis Ergonomics of the cab of agricultural tractors presents general ergonomics, its application in agricultural tractors and especially in the cab of agricultural tractors. The aim of this bachelor thesis was to compare five ergonomic features of five best-selling agricultural tractors in the Czech Republic, whose maximum engine power intersects at 202 to 206 kW. The methodology was selected based on the literature and adapted to the agricultural tractor operator. Finally, the trend in agricultural tractor cabs in terms of ergonomics was presented.

The workstation in the tractor cab.
LÍKAŘ, Ondřej
The thesis is focused on the operator environment in the tractor cab. More precisely, the noise and dust in the tractor cab when stubbleng, plowing and sowing carried out under the autumn field work. Measurements were carried out in five farmers as five different tractors similar performance. As reference was used Zetor 12145, which was compared with New Holland T6070 Tractor, Landini Powerfarm 100, 135 Zetor Fronterra and Deutz-Fahr M620. The results of all measurements were graphically displayed and compared each other. In conclusion, the results were compared to measurements with the legislation. The measurement spat out of the rear tractor does not exceed the noise limit, which indicates the legislation. Dust measurements was more indicative of the diversity of the weather.

Comparison of taxi services in selected metropolises
Páchová, Markéta ; Zemplinerová, Alena (advisor) ; Gráf, Václav (referee)
This thesis is focused on different government approaches to taxi market. It discusses necessity of regulations in this branch. The core part of this thesis is empirical analysis of taxi markets in London, Dublin, Paris, Stockholm, New York and Prague. To study the subject more complex I also examined PHV (private hire vehicle) market which provides almost the same kind of services but it is not regulated. These markets are compared in term of supply -- number of cars per capita and price, and also in term of demand -- utilization of cars and customers content. According to this comparison I tried to find out if any of these approches can be considered as optimal, and wheather if regulated or deregulated markets bring better results. This thesis also discusses the best way how to deregulate entry into the taxi market. This will be illustrated by case study of entry deregulation in Dublin. I also provide some recommendation for taxi market in Prague.
