MacPherson Suspension Kinematics Analysis
Trnková, Lucie ; Fojtášek, Jan (referee) ; Hejtmánek, Petr (advisor)
This bachelor thesis deals with the influence of the position of significant points of MacPherson strut on kinematic characteristics. The first part contains a description of selected suspension parameters, their impact on the driving properties of the car, and a description of MacPherson strut. Furthermore, based on provided data, is prepared a detailed analysis of the influence of kinematics points to individual characteristics. In conclusion, all findings are synoptically summarized so that they can serve as a manual for change of the kinematic characteristics.

Study of torque vectoring clutch design
Cupák, Václav ; Porteš, Petr (referee) ; Fojtášek, Jan (advisor)
This work deals with the design of right and left torque vectoring control used in heavy commercial vehicle powertrains. The beginning of the work is focused on the description of the active differential system and on the clutches used in the automotive industry. Then the basic parameters of the experimental vehicle are defined and the choice of the clutch conception is made. Subsequently, calculations of geometric parameters of clutches and verification of their heat capacity is made. Conceptual design of the control mechanism is discussed in the last chapter. The aim of the work is the draft of the possible type of control mechanism for the given system with the possibility to use the information obtained for the further development of this system.

Alternative conceptions of combustion engines
Šťáva, Martin ; Fojtášek, Jan (referee) ; Zháňal, Lubor (advisor)
The subject of this bachelor´s thesis on the topic Alternative conception of combustion engines is description of chosen historical and present alternatives to conventional piston combustion engine with crankshaft. The aim of this thesis is to create thesis that relates description of historical evolution of alternative construction combustion engines. Alternatives are described in terms of construction, operating principle and properties. In past were developed plenty of different conceptions of combustion engines. However most of them have never been successful because of many technical problems, complicated construction or other shortages.

Machine learning and signal processing
Kolář, Michael ; Fojtášek, Jan (referee) ; Zháňal, Lubor (advisor)
This thesis deals with the possibility of using neural networks in the analysis of a racing vehicle telemetry data. The analysis consists of finding and classifying the driving states of the vehicle as well as reconstruction and prediction of the data signal. The thesis consists of a research of machine learning focusing on neural networks. It describes the main types of the most commonly used neural networks with the description of their structure and their learning process. It also deals with the problem of classification and an in-depth analysis of the signal prediction and reconstruction. The conclusion is devoted to the implementation of the network into a TeleMatrix application.
