Race car diferentials
Kimlová, Anna ; Prokop, Aleš (referee) ; Janoušek, Michal (advisor)
This thesis deals with the most common differential design solutions. The first part examines the reasons for mounting of differentials. The second part is a summary of the most commonly used differentials. The last part is dedicated to differentials used in sports and race cars, i.e. active and self-locking differentials.

Acoustic Holography
Vacula, Jan ; Janoušek, Michal (referee) ; Prokop, Aleš (advisor)
This bachelor´s thesis is focused on description and process during contactless identification of sound source for near and far field. Principles of individual methods of acoustic holography are relatively shortly described and for details of this problem (on the level of algorithm of software equipment) you can see the references below thesis, which were the basic theory of my study. The introduction was conceived like description of “acoustics world”. You can find the basic information and principles about sound propagation in space and their mathematical contain at time. For this it was essential to define quantity and their units. Subsequently there is inventory of used sensors and their own construction for this measurement. Next chapter point to some techniques of acoustic holography used in practice. It includes mainly a method NAH (Nearfield Acoustical Holography) and SONAH (Statistically Optimised Nearfield Acoustical Holography) used for near-field. For reconstruction of far-field is shown principle of a method of Beamforming and manual measurement by intensity probe. The ending is focused on a concrete application these methods on combustion engines of cars.

Measurement and Evaluation Methods of Powertrain Vibrations
Vítek, Michal ; Janoušek, Michal (referee) ; Prokop, Aleš (advisor)
This bachelor´s thesis deals with the methods of measurement and evaluation of powertrain vibrations. Introduction of this work is defining the basic parameters of vibration. It also shows the experimental modal analysis, vibration excitation methods and measuring responses to a given excitation. The last part is operational modal analysis and its comparison with experimental modal analysis.

Noise Reduction Methods in Automotive Design
Kubica, Petr ; Janoušek, Michal (referee) ; Prokop, Aleš (advisor)
The aim of this bachelor thesis is create a research study about noise reduction methods in automotive design. The introduction of this work deals with acoustic and the influence of noise on people. Furthermore it deals with ways of noise creation in a car and its suppression. In the end of this work there is a valorization of certain methods at noise suppression of a personal vehicle.
