Raspberry Pi Pico with Ethernet
Zima, Jan ; Valach, Soběslav (referee) ; Burian, František (advisor)
This bachelor thesis focuses on the implementation of ethernet communication using microcomputer Raspberry Pi Pico and a physical layer chip. The communication is intended to be bidirectional between the microcomputer and other computer on a local area network (LAN) using the well-known MII interface. Microcomputer uses this network to communicate data which are acquired by distance sensors. A software which is outputting those acquired data to the console is implemented on the second computer. This thesis also focuses on a PCB design itself where individual electronic parts are connected making a functional circuit.

Wireless dalalogger
Linek, Tomáš ; Burian, František (referee) ; Kunz, Jan (advisor)
The bachelor thesis focuses on the design and implementation of a wireless datalogger. It includes a detailed description of the issues related to wireless transmission using LoRa technology, which was utilized in the implementation. Furthermore, the design of the entire device, consisting of a central logging unit and sensor units, is described. The thesis also covers the hardware and software equipment of the wireless datalogger, including a user desktop application. The outcome of the work is the construction of a functional datalogger enabling the logging of temperature and humidity from wireless sensor modules and measurement of its parameters.

Methodology for setting firewall rules
Vagner, Michal ; Jan,, Burian (referee) ; Sedlák, Petr (advisor)
This diploma thesis focuses on explaining the concept of firewalls, and especially next-generation firewalls. It introduces their specific representative Barracuda CloudGen Firewall, project management and technologies such as Python and RESTful API. Based on these findings it creates an implementation proposal for migrating and creating firewall policies on Barracuda CloudGen Firewall in COMGUARD a.s.

Multispectral Map Building in Mobile Robotics
Burian, František ; Mazal,, Jan (referee) ; Zemčík, Pavel (referee) ; Žalud, Luděk (advisor)
The dissertation deals with utilisation of multispectral optical measurement for data fusion that may be used for visual telepresence and indoor/outdoor mapping by heterogeneous mobile robotic system. Optical proximity sensors, thermal imagers, and tricolour cameras are used for the fusion. The described algorithms are optimised to work in real-time and implemented on CASSANDRA robotic system made by our robotic research group.

Automated station for DC and AC measurements
Burian, Josef ; Jeřábek, Jan (referee) ; Koton, Jaroslav (advisor)
he object of this work is the suggestion of workplace for measurement of direct-current and alternating current quantities. This work is divided into several basic units. There are described separate elements of the workplace by the HW over the bus line up to the SW in full details. The selection of HW and the suggestion of service program is approached in the next part. To the program creation was used environment for virtual instrumentation VEE 9.2 made by Agilent company. Resulting program is described in this work in full details. The last part of this work concerns with test measurement and valuation of the whole work.

Detection of Dynamic Network Applications
Burián, Pavel ; Drahošová, Michaela (referee) ; Kaštil, Jan (advisor)
This thesis deals with detection of dynamic network applications. It describes some of the existing protocols and methods of their identification from IP flow and packet contents. It constitues a design of a detection system based on the automatic creation of regular expressions and describes its implementation. It presents the created regular expressions for BitTorrent and eDonkey protocol. It compares their quality with the solution of L7-filter.

Design of cartridge spindle for milling machines
Burian, Viktor ; Vetiška, Jan (referee) ; Pavlík, Jan (advisor)
This master´s thesis deals with the design of a cartridge spindle for milling machines. The aim of the work is to design a spindle with a power of 15 kW, which allows the automatic exchange of tools with ISO interface. In the beginning, the thesis deals with the description of the individual components related to the construction of machine tools spindle. A spindle design concept is chosen, for which a number of calculations were made concerning the structure itself. Based on the proposed design, a 3D model and drawing documentation were made.

3D LED color display
Rak, Jan ; Burian, František (referee) ; Jílek, Tomáš (advisor)
The goal of this project is to design and construct a LED cube for visualization and imaging attract attention. With respect to the assignment was determined resolution 8x8x8. For the overall management and communication with the PC was chosen development board STM32F4 Discovery, which, thanks to it parameters, is sufficient for this application. Cube consisting of diodes and power wires will sit on the governing board, which will include all parts of management and communication. Implemented firmware will have a base animations, it is also possible to control by superior system.The board will be covered by colored fabric for a better look.
