Determination of Turbocharger Rotor Dynamic Properties
Blaha, Adam ; Zubík, Martin (referee) ; Novotný, Pavel (advisor)
This diploma thesis deals with dynamic behaviour of a turbocharger rotor. The subject is a stock turbocharger for commercial vehicles. The research will be mentioned in the first part of the thesis as well as methods of processing. The second, practical part is divided into two divisions. They are both experimental and computational. The aim is finding of rotordynamic behaviour by an experiment and its comparing with a computational model in ANSYS software. Modal and harmonic analysis of a free and fixed subject will be used by both experiment and evaluation. The subject will be fixed where bearings are located during harmonic analysis. All the experimental results will be processed with mathematical and physical methods like FFT analysis or Campbel diagram. There will be two main types of computational models to choose among. These models will be analyzed in detail. The goal of the thesis is to reach results from ANSYS as close as possible with the experimental testing. This includes finding correct material and physical properties, right choice of mesh and right boundary conditions. At the same time the CPU time compared to the model complexity and results accuracy will be considered in a comparison with data obtained by the experiment.

Modern methods of supercharger internal combustion engines
Blaha, Adam ; Mauder, Tomáš (referee) ; Štětina, Josef (advisor)
This bachelor´s thesis is aimed at the supercharged engines with the internal combustion. Here are mentioned various types of a charging considering design and use, typical diagrams appearance and the boost control. Considering the name of this bachelor´s thesis the old types of charging or these which are not in use today for any reason are not purposely mentioned here.

Contact microphones and their use in film practice
Bláha, Adam ; NEUBAUER, Petr (advisor) ; Titěra, David (referee)
The goal of this thesis is to introduce its reader to the problematics of various types of contact microphones in the field of film production. Rather than on technical specifications, it is focused on practical aspects of their use. It is dealing with specifics of handling such microphones, characteristics of the sounds recorded by them and with the possibilities of their use regarding the dramaturgy of films‘ soundtracks. Practical part of this work contains examples of these sounds as a demonstration of the claims, that I am introducing throughout this text.
