Probe for RFID cards tests at 13.56 MHz
Zigo, Viktor ; Vychodil, Josef (referee) ; Derbek, Vojtěch (advisor)
This thesis deals with RFID technology and the tag design for RFID device testing on the frequency of 13, 56 MHz. Everything regarding testing of such devices is described in ISO 18047-3 Standard. The target of this thesis is to design and construct the impedance matching (probe) between a proof coil and SW radio USRP N200 and the principles of this probe design are explained.

HF RFID tag emulator
Neužil, Ondřej ; Derbek, Vojtěch (referee) ; Vychodil, Josef (advisor)
This thesis contains the basic information about the Radio Frequency Identification (RFID) technology. It describes its main principles and usage. The main goal of this thesis is to design a RFID tag emulator for HF band according standard ISO 15693 that should emulate the long-range contactless smart card. The design includes the selection of the suitable components, such as a microprocessor - the core of the whole emulator, or calculation of the efficient integrated coil dimensions on a printed circuit and software for communication between the RFID reader card and the emulator.

Experimental tags for UHF RFID applications
Pacholík, Vladimír ; Holek, Karel (referee) ; Lukeš, Zbyněk (advisor)
This thesis deals with RFID tags design. It comprises an overview of the RDIF technology while focusing upon the passive tags in UHF band. The CST Microwave studio software has been used for draft simulations. The resulting tags have been subjected to parameter measuring – the reflection coefficient, the minimum capacity needed to switch on the tag, the maximum reading distance. The influence of the proximity of metal objects and other materials has also been examined.

High-Performance Platform for Malware Research
Plaskoň, Pavol ; Bartík, Vladimír (referee) ; Kolář, Dušan (advisor)
Anti-malware companies analyze large number of files every day. In order to speed up their analysis, many automatized tools were implemented. Detection definitions that detect malicious software are often generated automatically. Information about currently spreading malware is scattered across several tools and they are sometimes too generic. This work proposes a new tool that will aggregate, prioritize, and evaluate all the available information. Due to large amount of incoming data, high performance and scalability of the system is necessary. Files, detection definitions, and other objects will be tagged using the given information directly or inferred. Collected information will be accessible via interface for further analysis and statistics. Everything was implemented, tested and put into production.

Interactive presentation of audiovisual works in virtual reality
Abdulvaliyev, Chamit ; Miklánek, Štěpán (referee) ; Sikora, Pavel (advisor)
This bachelor thesis is focused on development of a VR application which allows presentation of audiovisual works in a virtual space. This thesis was created in collaboration with Vasulka Kitchen Brno as part of the project Vasulka Live Archive / Interfaces and uses works of Steina and Woody Vasulkas. The application allows playing videos on a virtual canvas, rewinding videos, visualizing predictions generated by a neural network, changing the sorting of the thumbnails and changing the virtual environment. The prediction and sorting data are loaded from JSON files provided by the supervisor of the thesis. The videos are loaded from local storage before being played. Predictions are visualized with generated textures for every tag. The user has access to two environments, outer space and gallery, which was modelled after the exhibition space Vasulka Kitchen Brno. In the outer space environment, the user can move using the joysticks on the controllers, which simulates flight with a jet pack. Video rewinding and changing of the video sorting is controllable using the buttons on the controllers. The game engine Unity was used during the development and the application was tested on the VR headset Oculus Quest 2. The text of this bachelor thesis is divided in two parts. In the first part, the basic VR development context and game engines which can be used are described. These game engines are described: Godot, PlayCanvas and Unity. The second part focuses on the development of the VR application and the results of the bachelor thesis. It details the process of preparing a virtual scene and working with Unity editor. Also it explains the functions of the used scripts and ways of solving the problems met during the development.

Electronic attendance book
Nezval, Tomáš ; Macháň, Ladislav (referee) ; Šandera, Josef (advisor)
This Master’s thesis deals with analysis of available identification chips and the design electronic attendance book that these chips will use and store the measured information to a file on a memory card. One of the tasks is to compare different kinds of identification cards and chips, and select the most appropriate type for the implementation process. Additionally, the work described the FAT file system, which is used for data storage card.

Design of meander RFID antenna
Horák, David ; Šebesta, Jiří (referee) ; Lukeš, Zbyněk (advisor)
This thesis deals with RFID tags. In the first part of the thesis, the general overviews of the present-day RFID systems are presented. This part of the thesis is focused on the passive back-scatter UHF tags and the advantages of their application in supply chain usage. Subsequently, the electromagnetic simulators CST Microwave Studio and IE3D Zeland are described. These simulators were used to design loaded meander antennas. The antennas were designed for different materials and frequency bands of 867 MHz and 2.4 GHz. The designed antennas were made without as well as with the reflector which allows using the antennas in the vicinity of metals. Produced antennas were experimentally tested in the company METRA Blansko Inc, where one of the most significant characteristics of passive RFID tags – the read range was observed.
