Diffusion Models and their Impact on Cybersecurity
Dvorščák, Patrik ; Homoliak, Ivan (referee) ; Lapšanský, Tomáš (advisor)
Táto práca skúma výkonnosť difúznych modelov (DM) a Generative Adversarial Network (GAN) - Generatívna sieť súperiacích komponentov, pri vytváraní vizuálneho obsahu generovaného umelou inteligenciou vo viacerých aplikáciách vrátane syntézy tváre, generovania textu na obraz, umeleckého renderovania, prekladu obrazu na obraz, syntézy videa a superrozlíšenia. Prostredníctvom porovnávacích experimentov sa v tomto výskume hodnotí schopnosť modelov generovať podrobné, realistické a umelecky presvedčivé vizuály z textových a obrazových vstupov. Výsledky ukazujú, že DM vynikajú pri vytváraní vysoko detailných obrazov, ktoré presne nasledujú textové vstupy, pričom sú obzvlášť účinné pri úlohách syntézy tváre a prevodu textu na obraz. Naproti tomu GAN sú zručnejšie pri vykresľovaní realistických scén prostredia, ktoré sú vhodné pre aplikácie vyžadujúce pohlcujúce vizuály. Oba typy modelov sú kompetentné v umeleckom vykresľovaní, hoci sa líšia v prispôsobovaní štýlu a kreativite. V závere práce sú uvedené budúce smery výskumu zamerané na zvýšenie účinnosti modelov a efektívnejšiu integráciu týchto technológií do praktických aplikácií.

Web Page Classification
Kolář, Roman ; Burget, Radek (referee) ; Bartík, Vladimír (advisor)
This paper presents problem of automatic webpages classification using association rules based classifier. Classification problem is presented, as a one of datamining technique, in context of mining knowledges from text data. There are many text document classification methods presented with highlighting benefits of classification methods using association rules. The main goal of work is adjusting selected classification method for relation data and design draft of webpages classifier, which classifies pages with the aid of visual properties - independent section layout on the web page, not (only) by textual data. There is also ARC-BC classification method presented as a selected method and as one of intriguing classificators, that derives accuracy and understandableness benefits of all other methods.

Assemblying effect on cable lines quality
Dočkal, Martin ; Křepelka, Václav (referee) ; Filka, Miloslav (advisor)
In the first part is explained what actually a structured cabling is. Its beginning, from what and why it was created. Its history when at the beginning were applied unbalanced coaxial cables, those were later replaced by balanced cables. In cabling for TVs are still used coaxial cables. Balanced cables are according to type named UTP, STP, FTP, and so on. Whit growing popularity of this type of cabling and its wide spread application was necessary to set some rules, standards, specifications and demands, how to build up the cabling from project to realization. According to these rules is the system built so there are strict rules for length of subsystems and interfaces and the whole appearance of the structure cabling. Next important point is projecting of cabling that is related to the previous points and when it’s finished, we should strictly follow it. With the project is closely connected characteristic of this cabling as attenuations, cross-talks and other transmission parameters which are measured in the practical part. In the second part is spoken about all the parts of which the structured cabling consists - metallic and optical connecting elements and cables. There are also mentioned their mechanical, electrical and transmission features. In the third part is described influence of man on the quality of structured cabling and the most common causes of lower quality and the ways how to prevent this from happening and how to manipulate with cabling not to destroy it. The final (fourth) part considers the measurement. There are measured qualities of metallic wires as the attenuations, delay, cross-talks on the near- and far-end, impedance and resistance. To all the features are mentioned schemes of the measurement on the twisted pairs. The measurement is divided into two parts. In the first part are measured five types of balanced cables of different length, category and damage influencing quality of these cables. In the second part is measured one balanced cable if it’s corresponding with category 5 for that t was made and if it would be possible to use it also for higher category 6. Values are tabularly sorted in tables.

"Some trees flourish, others die?": Opportunities and Problems of the Video game Canon
BRIXÍ, Václav
The paper attempts to enter current discussions related to the perception of video games as art. The thesis will focus primarily on the emergence of the video game canon, and will trace the evolution of this entertainment industry towards an increasingly institutionalised reception and evaluation of video games. This development will be examined both in academic context, with attention paid, for example, to the emergence of university departments and scholarly monographs on the history of video games. At the same time, the author will focus on non-academic strategies of value creation, such as the operation of the The Game Awards event, or the efforts to establish a normative genre-based system of video game creation and evaluation by game developers, journalists, and emerging critics. Methodologically, the thesis will draw on the theory of the canon of other arts, with particular attention to the development of the film canon as an example of the establishment of a new art and its institutionalization during the 20th century.

IT infrastructure monitoring system using robotic process automation
Valíček, Matěj ; Mikulášek, Michal (referee) ; Sikora, Marek (advisor)
The goal of this bachelor’s thesis was to create a tool for categorizing elektronic mail using Robotic Process Automation (RPA). The categorization is based on a message with category „_TEMPLATE“ and the similarity of its subject with the subject of the incoming message. The robot further analyzes the punctuality of the messages and in case of delay, the administrator is notified about the situation. Finally, messages are moved to the archive folders so that only one message from each subject remains in the main folder at any time.
