Design of Device for Tyre Rolling Resistance Measurement
Piskoř, Martin ; Blaťák, Ondřej (referee) ; Hejtmánek, Petr (advisor)
The aim of this thesis is a construction concept of tyre rolling resistance measuring device. The first part deals with the rolling resistance. It describes its causes, its influential factors and it also includes rolling resistance identification methods. The second part deals with construction design of the rolling resistance measuring device itself. It contains stress analysis, and fatigue analyses as well. It includes selection of transducers used for tyre rolling resistance measuring and also measurement error analyses. The last part focuses on estimated financial requirements connected with producing and assembling the designed measuring device.

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.

Motivation of the Manufacturing Company Employees
Tomíšková, Tereza ; Kašparová, Eva (advisor) ; Chládová, Martina (referee)
The following BA thesis deals with employees' motivation, its main focus being the inner motivation of the workers, their needs and motivation profiles in general. The work consists of a theoretical account of the said problematic reaching from explaining the basic terminology and sketching out the selected motivation theories to the concept of the worker in a certain company. This is followed by the practical part where the selected manufacturing company as well as the results of the carried out analysis are presented. These data were provided by means of a written enquiry about a certain part of the production, and their aim was to confirm or to falsify the beforehand laid down hypotheses. These were above all concerned with the personal characteristics of a worker employed in a manufacturing company.

Legislative problematics of rubber waste processing
Harant, Petr ; Říhová, Zora (advisor) ; Janovský, Vladan (referee)
This diploma thesis deals with the issue of rubber waste legislative focusing on waste tyres. The aim of the thesis is a thorough analysis of current legislative including newly prepared alterations with emphasis on specific lingering problems. A project of secondary material recycling, which has been created in current legal conditions, will be introduced. The project is assessed in terms of project managment methodology and the thesis concludes by suggesting an ideal project managment approach for realization of similar projects. Close cooperation has been established during realization of the project. At the same time, relevant government offices have been asked for information on the legislative and the whole issue has been consulted with respective offices. The introduction of the thesis familiarizes readers with basic points connected with project managment and tyres characteristics. Subsequently the relevant legislative related to waste tyres is mapped. The last part of the thesis is devoted to secondary material recycling project and its conclusion suggests the course of each of the project's life cycle stage using knowledge of project managment.
