Production of a part of the TV bracket
Vodák, Marek ; Jopek, Miroslav (referee) ; Podaný, Kamil (advisor)
This master’s thesis is focused on the design of the technology to produce a part of the TV bracket. The part is made of steel sheet with a thickness of 2.5 mm. The structural steel S235JR was chosen as the most suitable material with following powder coating. From the possible variants, the production by progressive forming tool was chosen with respect to production requirements and a series size of 30 000 pieces by year. The part will be made in seven steps in designed tool and the total required force is 1013 kN. The production will take place on a mechanical press PCK12 from Bliss-Bret with a maximum force of 1250 kN. The final price of the part is 39.4 Kč.

Increasing the life of cutting blades by coating
Vodák, Marek ; Lidmila, Zdeněk (referee) ; Podaný, Kamil (advisor)
This Bachelor Thesis presents the possibility of increasing lifespan of cutting blades made of 19 436 steel, which are used for the production of stator sheets made of silicon steel. Its high amount significantly increases the hardness of the material, which adversely affects the lifespan of the tool blade. After selecting suitable methods, coating was chosen. Its use is limited by the resistance of the material to tempering with a maximum temperature of 520 °C. Therefore, it is necessary to choose a PVD method, more specifically arc evaporation, which runs at temperature below 500 °C. From a range of suitable coating the multi-layer FeinAl coating, which has excellent properties thanks to chemical composition and structure composed from many fine layers, was selected.

Vývoj informačních systémů veřejné správy v České republice a Evropské unii
Vodák, Marek
The thesis evaluates development of electronic public administration in the Euro-pean Union and compares current situation in the Czech Republic, Slovakia and Estonia. The first part describes electronization of public administration especially on the european level -- which steps were made by the European Union to instigate the member states to build more effective and friendly public administration. The second part introduces current major projects of public administration in the Czech Republic. In the last part, you can find comparison of public administration portals of chosen states and in which rate are online services of public administration used.
