Vliv hnojení sírou na produkci a kvalitu cibule kuchyňské
Pilař, Tomáš
The aim of this thesis was to evaluate the influence of the variety, dosage, form and the terms of sulfur fertilization in the production of onions. Without otherwise not altered amounts of other nutrients was evaluated the effect of half, whole and halved the dose of elemental sulfur and sulfate forms on yield, storability, sulfur and nitrate in onions. Issues was solved through field experiment in 2014, in Loděnice near Mor. Krumlov. Yield and storability of onions were statistically significantly affected by the dose and form of sulfur and varieties of onion. Sulfur fertilization had a statistically signifi-cant effect on the nitrate content and ratio of nitrogen and sulfur contained in onions. The results shows us, that the higher dose of sulfur fertilization was more effective than the lower dose of sulfur.

Draft controlled modular source 6,3kA / 5VAC for warming trials and tests breakers
Zolich, Ladislav ; Dostál, Lukáš (referee) ; Dohnal, Petr (advisor)
The main object of this thesis is to design a toroidical transfomer on the given parameters. Project is focused on learning about principles of transformers, it’s designing and mainly on designing the given transformer. Designing contains material selection of the core of the transformer, its size, then calculating magnetic flux, no-load current, cross-section of conductor and calculating no-load losses and joule losses. The next part is designing the mechanical parts of transformer, its terminal plate, base and cooling system. Thesis is also mainly focused on designing the form for potting the transformer in epoxy resins. In the end is measurement and form of powering the transformer.

Comparison of Two Technology with Al-pressure-cast
Daniel, Jakub ; Jaroš, Aleš (referee) ; Kalivoda, Milan (advisor)
The project elaborated design of two manufacturing technologies for component called counterpart of ball from alluminum alloy. Based on the literature study and consultation with the company CNC program was made for machining technology. For pressure casting the part was modified according to the technological requirements. Comparing these technologies showed preferable method of manufacturing for mass production.

Making sand moulds and cores for casting
Katrňák, Jiří ; Kaňa, Václav (referee) ; Pernica, Vítězslav (advisor)
Bachelor thesis describes various methods for the production of sand molds and cores in foundry and basic concepts associated with this issue. Due to the large number of production methods are described only basic and most widespread methods. The work includes the design and manufacture of cast-iron grate for the stove, made into a mixture of bentonite and self-hardening mixture AlpHasetTM.

Construction of molds for rubber molding
Bátrla, Martin ; Brandejs, Jan (advisor)
This Bachelor’s thesis contains the general body of knowledge related to theory of injection molds for rubber molding. There is also described a designing procedure of mold for rubber cuff which will be used as a protection against the dust and other impurities. The output is a 3D model of injection mold made in SolidWorks 2015 and 2D documentation of chosen parts.
