Hydrobike - feasibility study
Kunovský, Lukáš ; Kárník, Jan (referee) ; Štigler, Jaroslav (advisor)
This bachelor thesis presents a project of hydraulic system which is intended specifically for bicycle drive and is realized through hydrostatic transducers. It gives information about necessary components and about the procedure of their selection. In this procedure it focuses particularly on weight reduction and loss minimization. Apart from the considerations as such, it also analyzes prior concepts and adopts suitable improvements from these. In the presented plan it demonstrates a method of effective verification of the real parameters of the whole as well as of the partial components.

The study wheeled undercarriages of mobile machines
Olšovský, Petr ; Škopán, Miroslav (referee) ; Kašpárek, Jaroslav (advisor)
The objective of this bachelor thesis is to summarize basic findings regarding various types of wheeled undercarriages that are used on contemporary machines. The first part of this paper deals with numerous requirements that should be fulfilled by the design of an undercarriage. The fulfilment of these requirements also helps to assess whether the design should be used for a specific machine. Another focus of this paper is to summarize all design solutions regarding propulsion, tyres, stabilizing elements and steering mechanisms. These solutions are compared to each other. Important design elements of wheeled undercarriages are described as well.

Classification and evaluation of rail wear
Nohel, Rostislav ; Frýza, Josef (referee) ; Galas, Radovan (advisor)
This bachelor’s thesis is focused on the wear of rails. In this thesis, the reader will be firstly introduced to the fundamentals such as nomenclature of wheel and rail, adhesion, adhesion coefficient, contact area, slip, traction characteristic and wear. Subsequently, the fundamental types of material wear (adhesive, abrasive and fatigue) will be explained, which occur in the wheel-rail contact. In the next part, the individual rail defects are analysed with respect to locations. The output of the bachelor’s thesis is overview and description of the most common rail defects which are usually caused by fatigue wear.

Cycling tourism and its importance to the development of tourism in the region
FRANCOVÁ, Vendula
The aim of this work was to evaluate the present condition of cycling tourism and its importance to the regional development of tourism in the region of Klatovy. The starting point was to define tourism and cycling, to explain basic terms, then to specify the region. The following analysis defined the primary and secondary offers of the region. On the basis of my questionnaire research there were suggested new options of developing cycling and tourism in the region of Klatovy. These ones reccomend to focuse on the region promotion especially on the internet and in the information centres. Additional services as lay-by places, litter bins or larking stands are missing and that was found as one of the main imperfections of this region. This situation expected to be improved. There was proposed the improvement of the services for cyclists {--} bike rents, bicycle repair shops, cycle stores. National certificate system {\clqq}Cyclists Welcome`` helps to improve services of accommodation and food facilities and to increase visiting sights. If some options are realised, it will lead to the enlargement of the offer, attracting more tourists and improvment the offered services.
