Analysis and comparison of elementary school educational programs in the Czech Republic based on the findings of the Czech School Inspectorate survey
Medek, Petr ; Rusek, Martin (advisor) ; Tóthová, Martina (referee)
This thesis presents research on primary schools in the Czech Republic, selected according to whether they were included in the Thematic report of the Czech School Inspectorate in 2023. The thesis focuses on the results of this report for the educational field of Chemistry. Within the theoretical part, the gradual development of curriculum documents in the Czech Republic is elaborated with regard to the currently ongoing revision of the RVP ZV. In the practical part, an analysis of the school curriculum of the given schools is worked, focusing on the distribution of the number of teaching hours in the educational field of Chemistry within the educational field of Human and Nature, as well as an analysis of the distribution of available hours in the educational fields. An analysis of the amount of active verbs in the expected outcomes and whether primary schools have included teaching methods in their school curriculum is also made. The final section shows, among other things, that the highest number of available hours is devoted to the educational area of Human and Nature (median of 6 teaching hours), that the teaching of the educational area of Chemistry still persists under the title of Chemistry in the eighth and ninth grades with two teaching hours each, and that the highest number of teaching...

3D printed microstrip patch antenna
Medek, Petr ; Vašina, Petr (referee) ; Láčík, Jaroslav (advisor)
The bachelor thesis deals with the issue of inhomogeneous substrates of microwave patch antennas. The aim of this work was to find such a distribution of the permittivity of the substrate of a linearly polarized patch antenna, which would be possible to achieve an extension of the impedance bandwidth to an antenna with the same effective permittivity. The investigated patch antenna has a square shape, is linearly polarized, and is powered by a coaxial power supply. Few types of permittivity distribution are presented and compared with an antenna with a substrate with an adequate effective permittivity. For each antenna, the dimensions of the patch are adjusted so that the antenna is designed at a medium frequency of 2.45 GHz. Furthermore, an antenna with a constant permitivity with patch dimensions is designed and the permittivity of the substrate is adjusted so that the required frequency is achieved. In the two investigated styles, we observe an extension of the impedance bandwidth to the antenna with adequate effective permittivity in the order of hundreths of percent, which was subsequently verified by manufacturing and measuring.

Tor Network Simulators: Comparison and Usability
Medek, Petr ; Grégr, Matěj (referee) ; Polčák, Libor (advisor)
This thesis talks about simulations of Tor network through simulators Shadow and Tor Path Simulator. As a part of the thesis was created web application using Tor Path Simulator that demonstrates principles of Tor network operation and attacks on it. Created application will run simulations according to parameters input by user and results will be shown using graphs and tables. Application was used as a basis for teaching materials. In my thesis I also focus on Shadow simulator and its usage.

Learning Software for Visual and Text-Based Programming in Lua/LÖVE
Medek, Petr ; Křivka, Zbyněk (referee) ; Rychlý, Marek (advisor)
This thesis pertains visual programming in Lua language with LÖVE framework. Within this thesis was created web application for teaching programming in Lua/LÖVE. Application supports both block and text based programming. Created games can be easily launched on Android platfrom using the Android app that was created in this thesis. The web app also includes tutorials that are well suited for education in schools.

Ulyxes alias Pavel Minařík
Medek, Petr ; Köpplová, Barbara (advisor) ; Suk, Pavel (referee)
This dissertation describes the life of Pavel Minarik, a journalist but also secret police agent, who worked at Radio Free Europe in Munich and in several exile organizations. It also provides a brief overview of the situation in Czechoslovakia in the 2nd half of the 20th century, the development of the security apparatus of the country after World War II (focusing on the secret police and intelligence service) and the foundation of Radio Free Europe. The work refers to the studies on the topic, secret police archives, and also memories of the "Munich radio" reporters.
