Aggregation and propagation of disturbances in the transmission system
Šedivý, Tomáš ; Rajský,, František (referee) ; Drápela, Jiří (advisor)
This thesis is devoted to the analysis and simulation of disturbance phenomena in the transmission system of the Czech Republic with emphasis on harmonic voltage distortion. A simulation model was developed in PSCAD environment, which allows to study the propagation of harmonic components in a congested system with multiple interconnected substations under different operating scenarios. The simulation results provide a deeper understanding of the aspects affecting the propagation of mainly harmonics in the network and lead to suggestions on how to effectively analyze the propagation of disturbances on a larger scale network.

Technical and economic comparison of electrical system designs of the hotel complex
Šedivý, Tomáš ; Jurák, Viktor (referee) ; Ptáček, Michal (advisor)
The aim of the bachelor thesis is to implement the designs of electrical power supply of a selected hotel complex and related technical and non-technical comparison. The subject is specifically to compare the power supply solution options through a centralized power centre, separate transformer stations located within the complex, for example in terms of the evaluation of active power losses on the line, investment and operating costs or in terms of space requirements, etc.

Changes in photography under the pressure of digital era
Šedivý, Tomáš ; Láb, Filip (advisor) ; Géla, František (referee)
This bachelor thesis consists of two parts - practical and theoretical. The practical part is an audiovisual documentary based around five interviews with five personas of artistic and journalistic as well as amateur photography. It sheds light not only on their views on the photography medium but also on their own creative process related to it. The theore- tical part follows up the interviews and further develops the subject of changes in photo- graphy, notably the means of photojournalistic work and its perception in society. It sket- ches a brief history of photography and internet environment but its main focus lies in the transition from the analog era to digital technologies at the turn of millennium. It describes the trend of social networks, digital filters and influencers through which a return of the analog photography can be witnessed in the recent years.
