Security Analysis of Selected SOHO Router
Richtarik, Jakub ; Holop, Patrik (referee) ; Tamaškovič, Marek (advisor)
Pre narastajúci počet zamestnancov pracujúcich na home office a zvyšujúci sa počet IoT zariadení v domácnostiach, je čoraz viac potrebné používať dostatočne zabezpečné smerovače. Cieľom tejto práce je preskúmať vybrané SOHO (small office/home office) smerovače, zástupcov aktuálne predávaných domácich smerovačov, z pohľadu bezpečnosti. Dokument taktiež demonštruje postup a metódy, ktoré je možné použiť pri testovaní a analýze iných smerovačov a IoT zariadení.

Optimization of the digitron testing process
Stuchlík, Lukáš ; Valach, Soběslav (referee) ; Honec, Peter (advisor)
This bachelor thesis focuses on the optimization of a nixie aging machine in order to increase its reliability. In the introductory part of the thesis, an analysis of the current state of the machine is made, describing its unreliable operation and related problems in the production process. Based on this analysis, specific modifications in both hardware and software areas have been proposed. The main changes were the change of topology for current control and the addition of necessary components or complete circuits. These modifications were then implemented, which included the fabrication and testing of new printed circuit boards (PCBs) and the implementation of new firmware. In conclusion, it is confirmed that the modified machine exhibits reliable operation for the purposes of actual aging, but further requires minor modifications.

Automatic hydroponic microfarm for plant cultivation
Takács, Peter ; Janoušek, Jiří (referee) ; Szabó, Zoltán (advisor)
This thesis deals with the implementation of hardware and software design for an existing hydroponic micro-farm. The thesis includes a literature and internet search focused on automated plant cultivation. A description of different types of soilless cultivation systems is given in the thesis. General plant requirements are addressed and these requirements are thoroughly discussed. Instrumentation using specific components is also described in the thesis. The system integrates a control unit, heating and aeration controls for the nutrient solution, adjustable lighting, and sensors for pH, EC, and adjustable water and ambient temperature. In addition, the advantages and disadvantages of two selected microprocessor units are discussed. Further, the operation of the microcontroller that controls the individual components is also described in the thesis. This thesis briefly describes the general circuitry of each component and includes circuit diagrams and the schematic of a printed circuit board. This thesis describes the program of the firmware and the functions of the web interface used to interact with the system. Additionally, it features remote control and monitoring capabilities via a web interface, with email alerts for external intervention needs. This thesis also includes the implementation of the electronics in terms of assembly and calibration.

Measurement parameters of communication via PCI Express
Dujiček, Ondřej ; Dvořák, Vojtěch (referee) ; Pristach, Marián (advisor)
This bachelor thesis deals with parameters affecting throughput of PCI Express bus and its main result is a design and implementation of a unit for measuring parameters of communication over PCI Express bus. The unit is implemented in VHDL language and its support on generating and measuring traffic at speeds up to 100 Gbps. Unit’s operation frequency, when implemented in Virtex 7 available at COMBO-100G , is 200 MHz. The implemented unit is controlled from software through MI32 interface and it is able to measure the amount of transferred packets and data in both receive and transmit directions. This information can be exported into software using MI32 interface.
