Localization of short-circuits on single side supplied HV line
Zíka, Jakub ; Jurák, Viktor (referee) ; Topolánek, David (advisor)
This bachelor‘s thesis deals with the localization of unilaterally fed short circuits on high voltage lines. The first part of the bachelor’s thesis deals with the research of the localization of unilaterally fed 1-Phase, 2-Phase and 3-Phase short circuits on the HV lines. Furthermore, individual types of short circuits are described here with suitable procedures for calculating the fault distance and definition of formulas for individual impedance loops. The second part of the bachelor’s thesis focuses on the implementation of these formulas for calculating the distance to the fault location. The input values of voltages and currents were simulated by a simple system model in the PSCAD program. Subsequently, a more detailed sensitivity analysis of individual types of short-circuits was carried out and possible detection of when individual calculation methods fail.

Design of a wing model for flutter testing
Zíka, Jakub ; Šplíchal, Jan (referee) ; Navrátil, Jan (advisor)
Bachelor thesis deals with the design of a wing model for testing the dynamic aeroelastic phenomenon of flutter. The first two chapters of the thesis present theoretical introduction to aeroelastic phenomena and scaling relationships. The third part describes the whole model designing process based on similitude requirements to a real wing. Bending and torsional stiffness along with mass distribution are the most important wing properties where similitude should be attained.

Small satellite dispenser structural optimization
Zíka, Jakub ; Symonov, Volodymyr (referee) ; Popela, Robert (advisor)
Diplomová práce se zabývá tuhostní optimalizací nosiče satelitů, tzv. Dispenseru. První kapitola uvádí přehled evropských vesmírných aktivit a poskytuje nezbytné technické pozadí týkající se nosných raket. Druhá kapitola se věnuje popisu tvorby výpočetního modelu, neboť veškeré výpočty, včetně optimalizace popsané v kapitole třetí, jsou založeny na metodě konečných prvků. Pro optimalizovanou variantu je ve čtvrté kapitole provedena základní pevnostní kontrola.

Distributed order management for restaurants
Zíka, Jakub ; Kofroň, Jan (advisor) ; Horký, Vojtěch (referee)
Order management software is vital to restaurants and other order-based businesses to keep track of their finances and the demands of their custo- mers. Many such products are available in the Czech market; however, it is often difficult to modify these existing solutions or interface them with new or different systems. In this thesis, we design and implement a new order management system called EasyPub. EasyPub works on GNU/Linux and Microsoft Windows operating systems, and allows external programs to ac- cess information stored within the system through an open communication protocol. Its creation is beneficial and contributes to innovation in the area of restaurant software. 1
