Environment mapping
Mohorko, Martin ; Pavlík, Jan (referee) ; Bilík, Martin (advisor)
This bachelor thesis deals with the description of possible ways of mapping the unknown environment, which could be in this case both environments - aerial and terrestrial. It is focused on mapping by radars and 3D scanners, through their history, distribution, scanning methods, methods of displaying data or description of output data to their practical application. Furthermore based on selected criteria, methods were compared and it was explained why and which method is preferable than the other one. There is also in this work mention of other methods used for environment mapping of today and their use and potential for several future applications. In the conclusion was outlined the possible use concept on the radar locating system in connection with the 3D scanner.

Options for the Determination of the Influence of Electronic Stabilization Systems of the Chassis on the Driving Dynamics of a Vehicle
Bilík, Martin ; Vémola, Aleš (referee) ; Panáček, Vladimír (advisor)
This diploma thesis deals with the possibilities of determining the influence of electronic stability systems on the chassis of the vehicle driving dynamics. In the introductory section is made theoretical analysis of road vehicle dynamics. Further description is made of some stabilization systems and situations and how to solve them by using these systems. Chapter 6.2.1 describes the methodology of practical experiment, which can determine influence of the stability system of the vehicle chassis on driving dynamics. The next chapter describes an experiment conducted and interpreted the measured values. The penultimate chapter is a simulation of this experiment using simulation software Virtual Crash. The last chapter is an evaluation of the experiment and compares the results with simulation programs using the same input conditions. The conclusion summarizes the results of this work.

Possible Materials for Crash-Test Dummy Construction
Pokorná, Veronika ; Coufal, Tomáš (referee) ; Bilík, Martin (advisor)
This diploma thesis is devoted to the possibility of using materials for crash test dummy construction. The thesis describes how crash test dummies evolved, what crash test dummies are currently available for crash test and what they are made of. The main aim of the diploma thesis is to design materials and process for production of a crash test dummy with human-like biofidelity. The thesis describes the way which the dummy will be manufactured using duralumin, rubber, alder wood and silicone polymer or agar.
