Testing of the relay communication according IEC 61850
Uchytil, Tomáš ; Topolánek, David (referee) ; Toman, Petr (advisor)
This thesis contains an overview of a new standard IEC 61850. Parts of the standard are described particularly. More space is devoted to the analysis of communication in substations and to features of horizontal GOOSE messages. The other part is devoted to testers of protection and their use in testing of communication in substations according with IEC 61850. The last part is a practical example of using the tester and software for communication network monitoring and measurement of reaction of the system which is controlled with GOOSE messages.

Use compact control systems to control lighting by DALI protocol
Uchytil, Tomáš ; Baxant, Petr (referee) ; Škoda, Jan (advisor)
This thesis describes the system of lighting control via digital signals. In particular DALI protocol, this is used as a standard in this control. There is description of possibilities of connecting control units and a principal of communication between a load and the control unit. Also this thesis contains the conception of control via compact control systems, where is used a converter RS232/DALI.

Application for Car Logo Recognition
Uchytil, Tomáš ; Götthans, Jakub (referee) ; Kadlec, Petr (advisor)
Práce se zabývá nalezením vhodné neuronové sítě pro rozpoznání loga automobilové značky a implementací a trénováním této sítě. Ta je následně implementována do mobilní aplikace, která umožňuje rozpoznání loga na základě nově pořízené fotografie, nebo na základě obrázku vybraného z úložiště mobilního telefonu.
