Laboratory exercise - IQRF module for measuring mesh networks
Goryl, Juraj ; Paluřík, Pavel (referee) ; Jablončík, Lukáš (advisor)
This bachelor’s thesis deals with creating a laboratory task integrated into the subject of "Communication Systems for IoT." The first part of the thesis consists of familiarizing oneself with the issues of the IQRF network, its topology, and the network’s capabilities. The thesis compares IQRF technology with other IoT technologies commonly used in this field. The practical part of the thesis comprises the design of a module for the IQRF transmitter TR-72DA in the form of a mini PCIe card. Another part of the thesis deals with establishing communication with the BPC-IoT board using the SPI bus, with temperature measurement used as an example. The final part of the thesis is the assignment for the actual laboratory task. The appendices also include schematics and source code of programs for both the BPC-IoT board and the IQRF transmitter.

Educational PocketQube Satellite
Veverka, Jiří ; Zamazal, Michal (referee) ; Povalač, Aleš (advisor)
Tato diplomová práce je zaměřena na návrh výukového satelitu typu PocketQube 2P (50x50x100mm) a pozemní stanice, které budou využívány ve výuce STEM laboratoří. Navržený systém byl navržen s důrazem na modularitu, snadnou výměnu za použití komerčních volně dostupných součástek a snadné pochopení subsystémů, které lze v družici tohoto typu nalézt, tedy palubní počítač, komunikační modul, napájecí systém a payload. Mimo vnitřních modulů byla vyvinuta i vnější konstrukce, která je celá vyrobena z desek plošných spojů a dohromady tvoří základ družice. Vyvinutá družice a pozemní stanice využívají ke komunikaci rádiový modul RFM98W s modulací LoRa.

Web Portal for Network Traffic Anotation
Málik, Peter ; Tobola, Jiří (referee) ; Žádník, Martin (advisor)
Bachelor´s thesis aim is to create a system for network traffic anotation. For this purpose it is necessary to correctly determine the protocols for all layers of the network model TCP/IP. To identify the application layer protocol is used a method based on port numbers and a method based on tracing the signatures in packet´s data field by using regular expressions. Web portal was written in PHP, using the extension phpcap and tcpdump program, which provides manual anotation of network traffic.

Overview of the development of small and medium lauchers
Dítě, Radovan ; Petrásek, Miloslav (referee) ; Daněk, Vladimír (advisor)
This bachelor's thesis describes the development of small and medium vehicle launchers. The dissertation is divided into four main parts. The first part deals with basic principles of rocketry and types of rocket propulsion. The second chapter describes historical develop-ment of rocketry. The third part describes the development of small and medium vehicle launchers. And the last part is dedicated to the description of current states of small vehicle launchers.

Unmanned Aerial System design competition
Malinowski, Matěj ; Navrátil, Jan (referee) ; Pejchar, Jan (advisor)
Bakalářská práce se zabývá návrhem malého bezpilotního letounu určeného pro soutěž Air Cargo Challenge 2015. Práce je uspořádána dle postupu vývojových prací. Na prvotní koncepční návrh navazuje volba vhodného tvaru letounu a jeho profiláže. Následuje výpočet letových výkonů, maximální vzletové hmotnosti a centráže letounu. Poslední část práce se zabývá konstrukcí letounu a je provedena analýza závislosti užitečného zatížení na hustotě vzduchu.

Overview of current spaceships
Špačková, Jana ; Daněk, Vladimír (referee) ; Zikmund, Pavel (advisor)
Target of this work is to create an overview of commonly used and in this time developed transports used for carrying payload to space and comparing these transportation means. First part of the work is divided into three sections, rockets reaching the Earth’s orbit, rockets flying bellow it and other means of space transport. These sections are further sorted by states and its stage of development they are currently in. Second part of the work is focused on comparing previously described transports from the perspective of safety, power and also costs needed for running and manufacturing them. In the end there are results from the comparing section of this work and comments on the probable path of the near future development of the space transportation.

Implement Rubber Duckies on Available USB Devices and Make a Practical Test
Do, Hung ; Holop, Patrik (referee) ; Tamaškovič, Marek (advisor)
Tato práce se zabývá problematikou počítačových útoků typu BadUSB, implementací jednoho ze zařízení (Rubber Ducky) a následnou obranou proti těmto typům útoků. Mým úkolem je rozbor funkcionality univerzální sériové sběrnice, komunikace mezi hostem a zařízením a slabiny proti BadUSB útokům. Za tímto účelem jsem implementoval composite (složené) USB zařízení při použití mikrokontroleru Raspberry Pi Pico a externí open source knihovny TinyUSB. S funkčním prototypem prezentuji čtenáři několik možných ochranných mechanismů před těmito druhy útoků na operačních systémech Microsoft Windows a GNU/Linux. Tato práce varuje lidi před nevýhodami USB funkce plug-and-play a nebezpečím při připojování neznámých USB zařízení do našich počítačů.
