Belt conveyor for brick chippings
Přecechtílek, Pavel ; Škopán, Miroslav (referee) ; Malášek, Jiří (advisor)
The aim of this thesis is to calculate and design a slant conveyor for the transport of brick rubble. The thesis deals with a description of belt conveyors, their main advantages and basic classification. The thesis also includes design of individual parts, a description of the components and characteristics of the transported material, including technical parameters. The thesis includes functional calculation performed by ISO 5048, 1994, identifying the main dimensions and design of the drive. The thesis also contains tensioning device design and strength calculation of tensioning the drum shaft. The thesis is accompanied by all the necessary technical drawings.

Design of reinforced concrete cylindric tank
Svobodová, Barbora ; Bažant, Zdeněk (referee) ; Zich, Miloš (advisor)
The bachelor's thesis deals with static analysis of a reinforced concrete cylindrical tank. The analysis includes load calculation for selected load cases and design of tank wall and bottom reinforcement. Load combinations and load effects were calculated using the Axis VM software. The thesis includes shape drawing documentation, as well as drawing documentation of bottom and wall reinforcement.

Belt conveyor for transport of quartz sand
Pech, Zdeněk ; Škopán, Miroslav (referee) ; Malášek, Jiří (advisor)
The aim of my bachelor thesis is the proposal for the inclined belt conveyor for the transport of quartz sand designed according to certain parameters. The introduction to this thesis is concerned with the use, advantages, disadvantages and dividing of the belt conveyors. Furthermore, there are mentioned the individual parts of the conveyors and their description or their use in general. On the basis of this general characteristics, there are chosen the individual parts of conveyors to solve my concept. These mentioned facts are connected with the functional and strength calculation, the proposal of the conveyor traction, the determination of the chief proportions and the proposal of the mechanical tension belt. To conclude my thesis there are presented the analysis and evaluation of functions of the machinery for different dampness and granulity of sand. The whole bachelor thesis is completed with demanded graphical documentation.

Electrically short multiband antenna for radioamateur use
Müller, Marek ; Šebesta, Jan (referee) ; Lukeš, Zbyněk (advisor)
The purpose of this work is identification with theory of EH antennas, do the simulation of one choice of model of EH antenna from literature and this model optimise on required frequency 14 MHz through the use of computer software CST Microwave Studio. The practical part of work is to produce choice model of EH antenna, to mete his properties and to verify use in real traffic. The EH antenna is an electromagnetic electrically short antenna, which can work as a transmitting or receiving antenna. The main characteristic of EH antenna is distributed radiating electromagnetic field, whose electric component E and magnetic component H are mutually crossed and orthogonal. The advantage of EH antennas is, that they have much smaller size on frequencies in order of magnitude MHz in comparison with conventional antennas (e.g. half-wave dipole). Their disavantages are their more complicated construction and tuning of the antenna, which must be made again, when the position of antenna is changed. Therefore the EH antenna is not so suitable for mobile application.

Engines for Le Mans Series
Herman, Pavel ; Blaťák, Ondřej (referee) ; Svída, David (advisor)
This bachelor´s thesis deals with the overview of development the drive units, which are used by racing cars of Le Mans endurance series, mainly the race 24 hours of Le Mans. In the first part is outlined the general characteristic the series and the race 24 hours of Le Mans itself. There are briefly described the instructions and the most important technological limitations, observed by designers. The second part contains an owerview of racing cars engines, which are interesting from the historical point of view either by their construction or by achieved success. The last part is devoted to the constructional comparison of drive units of present participants the Le Mans series, their description and the important technical specifications.

Uniform Marker Field on a Cylinder
Kříž, Radim ; Havel, Jiří (referee) ; Herout, Adam (advisor)
This work presents a new extension for Uniform Marker Field, which is able to detect UMF on the cylinder. First part of the text deals with Augmented reality and focuses on systems using markers. It discusses the actual state-of-the-art systems and its possibilities. After that it focuses more deeply on the marker system Uniform marker field and its grayscale variants. Next part of the work describes properties of the cylinder projected in real space. Important properties for detecting are discussed in detail. Then the proposal and description of detection algorithm is presented. Implementation of algorithm is tested and evaluated on the very end of this thesis.
