Conception of ATV (all-terrain vehicles)
Dosedla, Milan ; Vančura, Jan (referee) ; Porteš, Petr (advisor)
This thesis is review article of the current design and construction setup of ATVs. In the individual chapters are analyzed function of structural units and their advantages and disadvantages for the application. Much attention is paid to the design and construction of the brakes and axles. Work based on the analysis 30 models of ATVs from different manufacturers. This thesis reports the specifications of selected models. In conclusion we discuss the appropriateness of design solutions for different types of ATVs such as utility or sport models.

Control Systems of Gears Changing on Load in Tractors Gearboxes
Holub, Přemysl ; Svída, David (referee) ; Dundálek, Radim (advisor)
This bachelor thesis is interested in the overview of tractor’s gearboxes, which are changing on load. There are reasons, why it has to be costructed and there are requirements for it. There are also described PowerShifts, which allow us gear changing on load. After basic description of concrete gearbox, there is always some example of using in current tractors. In period named Mechanical gearboxes, wchich are changing partly on load there is more space for Zetor tractors and its gearboxes. In one of the last period there is important part about continuously variable transmissions where the driving speed is regulated steplessly. These gearboxes are considered to be modern technology of transfer engine torque.

Influence of physical parameters and age of power lines on PLC/BPL performance and reliability
Benešl, Lukáš ; Sláčik, Ján (referee) ; Mlýnek, Petr (advisor)
BPL technology is quite widespread nowadays and the public is also somewhat aware of it. This technology can be used as a means of communication without the need to install additional media and thus use the existing infrastructure. In an effort to use the full potential of the technology, BPL communication began to be used to monitor the current state of cables in distribution networks online. Where the technology is already fully implemented, the distributor can use the data to evaluate the current situation. In this way, BPL technology can be used as a diagnostic tool to test the quality of a cable connection on which not only time but also humidity and other external influences could have a significant effect.

Analýza faktorů ovlivňujících reprodukční vlastnosti nandu pampového
Muchová, Tereza
Focus of this diploma thesis is the analysis of partial influences having impact on the reproduction of Greater rhea. It captures a detailed description of the most common factors, such as housing, nourishment, season’s effect, climatic conditions, genetics and subsequent breeding of chickens. Included is an anatomical description of reproductive organs of both sexes and getting the reader acquainted with the social behavior of this animal. Thesis also consists of ethological observations of defined individuals with focus on the influence of the season on various daily activities. Finally, an analysis of the eggs is performed that includes the overall laying capabilities of the female, along with hatchability, fertilization and mortality of embryos. As an appendix of the diploma thesis you can find recommended precautions increasing the possibility to improve the level of reproduction for the breeders.

Transmissions of Passenger Cars with Hybrid Drive
Vaňourek, Jakub ; Řehák, Kamil (referee) ; Prokop, Aleš (advisor)
This thesis deals with transmission systems of passenger cars with a hybrid drive. The main reason for choosing this topic was its topicality. With increasingly strict emission standards, hybrid cars are coming to the fore. The first part of the thesis deals with the division of hybrid drives into individual categories according to the selected criteria. An example of a specific solution is then given for the individual categories and its construction, functionality and its advantages and disadvantages compared to cars with an internal combustion engine are described. In the following chapters, more complex hybrid systems are described in more detail in connection with construction and functionality. The conclusion is dedicated to evaluating the mentioned hybrid systems and outlining their potential use in the future.
