The latest trends and developments in the smartphone industry
Šteiniger, Jakub ; Haupt, Jaromír (oponent) ; Rujbrová, Šárka (vedoucí práce)
The main aim of this bachelor’s thesis is to take reader to the world of smartphone industry, which has even positive and negative effects on people. In the beginning of this thesis, history of mobile technology and evolution of the mobile phone generations is described. Subsequently a description of the most significant present trends and a brief outline of future trends follows. The next chapter is focused on the characteristic of the most significant smartphone brands, their mutual competitiveness and market share. The last chapter deals with comparison of various parameters of Apple and Samsung company, then a final summary is provided.

Evaluation of the use of cold kinetic deposition technology on materials used in electrical engineering
Šteiniger, Jakub ; Zimáková, Jana (oponent) ; Binar, Tomáš (vedoucí práce)
The master´s thesis deals with a process called cold kinetic deposition technology. Using this technology, a copper layer was formed on a sample with an aluminium base by high-pressure cold spraying at a pressure of 25 bar. In the experimental part, the influence of corrosion degradation in the salt chamber was assessed at the time cycles of 100 h, 200 h and 300h, where changes in internal and surface resistances before and after corrosion were measured. Subsequently, the analysis of corrosion products was performed, where the extent of corrosion attack was determined using an electron microscope. These methods led to a final evaluation of the boundary limits of the applied coating layer by cold kinetic deposition, after the effect of corrosion. Finally, a theoretical application of this technology was suggested. It was discovered that the sample placed and left in the corrosion chamber for the longest time was the most affected by corrosion. Finally, a theoretical application of cold kinetic deposition was proposed.
