Growth of highly doped ZnO nanowires
Andrýsek, Michal ; Macák, Jan (referee) ; Kolíbal, Miroslav (advisor)
This diploma thesis is about ZnO nanowires growth, their doping and analysis. High temperature and pressure oxidation of brass foil and deposition from effusion cell in oxidative atmosphere utilized for nanowires growth. The growth is affected by different temperature and pressure. It has been shown that under certain experimental conditions nanowires can be prepared by the former method. However, the growth was hindered when effusion cell was used.

Bridge across the I/11 road
Macák, Jan ; Šrubař, Jiří (referee) ; Panáček, Josef (advisor)
This diploma thesis deals with a project of a road bridge. The bridge is located on a second class road S 7.5/50 and goes over a I/11 road and a local road crossing in Bystřice. Three options of the road bridge are conceived out of which the connected beam girder is chosen for further development. A calculation of the structural stability of the load-bearing construction, that includes time analysis of the construction work (i.e. particular phases of the construction), is added to the project. The structural stability calculation is assessed in accordance with valid European standards. Drawing documentation, a time schedule and 3D visualization of the road bridge is also attached to the diploma thesis.

Slab concrete bridge
Macák, Jan ; Suza, Dominik (referee) ; Panáček, Josef (advisor)
This bachelor thesis is dealing with a design of a road bridge. This object is located on the 1st class road I/39 and is leading over the watercourse Polecnice. Crossbreeding of the road and watercourse is located on the 22,783 km above mentioned road. I have developed 3 variants. First variant is a slab from post-tensioned concrete with a height 0,85 m. Second variant consists of precast concrete beams DS - PP1 40/85 coupled with reinforced concrete slab with a minimum thickness 0,2 m. Third variant is again slab from post-tensioned concrete but with a sloping headboard.
