Technological stage of the rough superstructure of an library in Veselí nad Moravou
Vančo, Lenny ; Průcha, Aleš (referee) ; Šlanhof, Jiří (advisor)
The aim of my bachelor's thesis is to develop a technological project for the technological stage of the rough upper structure. For this work, I chose the construction of a new library in the town of Veselí nad Moravou. The project was created by Ing. Katarína Božková as part of her diploma thesis at the Faculty of Civil Engineering at the Brno University of Technology. It is a public amenity building. The library also includes a bookstore and a café. The technological prescription is prepared for reinforced concrete monolithic ceilings. Additionally, I will address the logistics of transportation routes, the bill of quantities, the design of the construction site setup, the selection of machinery, work safety, the inspection and testing plan, and the schedule plan.

Nginx Web Server Security Weakness Detection Tool
Wagner, Michal ; Perešíni, Martin (referee) ; Křena, Bohuslav (advisor)
This thesis focuses on the security of the Nginx web server and its configuration options, with an emphasis on the reverse proxy server feature. It explores available alternatives to Nginx and security threats to reverse proxy servers. The thesis also delves into methods of detecting these security threats through penetration testing and conducts research on existing tools for detecting security vulnerabilities in reverse proxies. In the practical part, a tool is developed to demonstrate security attacks and detect vulnerabilities on the Nginx server. The functionality of the tool is validated in a suitable testing environment, and based on the gained experience, a technical specification is formulated for configuring the Nginx reverse proxy server to limit its susceptibility to attacks.

Privacy Preserving Smart-Contract Platforms and E-Voting
Žiška, Marek ; Homoliak, Ivan (referee) ; Perešíni, Martin (advisor)
Táto práca analyzuje platformy na ochranu súkromia ako Secret, Phala a Oasis Network, ktoré poskytujú nástroje pre vývoj smart kontraktov s možnosťou privátneho úložiska a dôverných výpočtových schopností. Platformy porovnávame na základe ich vlastností, ako je výkon, použiteľnosť a ďalšie faktory v kontexte prípadu použitia v elektronickom hlasovaní. Najprv predstavíme teoretické základy v oblasti volebných systémov, blockchainové technológie, smart kontrakty, technológie dôverného výpočtu a v neposlednom rade jednotlivé platformy na ochranu súkromia. Na základe zistení navrhneme volebný proces nášho smart kontraktu elektronického hlasovania, ktorý budeme implementovať na všetkých platformách. Následne analyzujeme možnosti a schopnosti vývoja každej z platforiem, najmä pokiaľ ide o definíciu štruktúry úložiska. Okrem toho navrhneme aj scenár hodnotenia, ktorý budeme vykonávať na každom z vyvinutých smart kontraktov. Po návrhu kľúčových častí smart kontraktov prechádzame k implementácií, kde diskutujeme o našich skúsenostiach, o použitých nástrojoch, o spôsobe zbere a vyhodnotenia štatistík a o metódach testovania. V rámci tejto fázy sme taktiež vyvinuli aj skripty, ktoré zbierajú štatistiky z navrhnutého scenára hodnotenia elektronického volebného systému, ktoré použijeme na vyhodnotenie a porovnanie týchto platforiem. Na záver zhrnieme dosiahnuté výsledky, kľúčové poznatky, úvahy a potenciálne oblasti pre budúce zlepšenia.

Performance Comparison of Libraries for Homomorphic Cryptography
Babjak, Pavol ; Tamaškovič, Marek (referee) ; Malinka, Kamil (advisor)
Kryptografia je neoddelitelnou súčasťou oblasti počítačovej bezpečnosti. Pri využívaní bežných kryptografických metód a operáciách nad nimi však nie sú jednotlivé dáta nijako chránené proti neoprávnenému prístupu alebo krádeži tretími stranami. Homomorfná kryptografia rieši presne daný problém, teda dokáže pracovať s dátami, ktorých obsah nepozná a súčasne vykonávať operácie nad nimi. Cieľom práce je vykonať sadu testov pre jednotlivé prostredia implementujúce homomorfnú kryptografiu rôznych schém a pomocou spúšťania rôznych typov operácií zmerať ich výkonnosť a ďalšie dôležité aspekty pri výbere najvýhodnejšieho prostredia pre riešenie daného konkrétneho problému.

Technological stage of the rough superstructure of the Horova Brno apartment building
Kadlec, Josef ; Kantová, Radka (referee) ; Doubek, Rostislav (advisor)
The bachelor's thesis deals with the construction-technological preparation of the rough superstructure of the Horova apartment building, which is located in Brno. The apartment building is planned in a gap and consists of three parts, the highest of which has 5 above-ground floors. The building has masonry made of brick blocks and the ceiling structures are monolithic. The construction-technological preparation of the building consists of a technical report for the Horova apartment building, the situation of the building with wider relations of transport routes, a list of dimensions, a technological regulation for the realization of monolithic ceiling and monolithic vertical structures, a solution to the construction organization, a time schedule, a design of a machine assembly, quality requirements and their provision for resolved processes, work safety for the implementation of monolithic constructions, itemized budget, contract for work between the main contractor and subcontractor and contract for renting a room for the construction manager.

Stress analysis of eye bolts
Kareš, Pavel ; Kubík, Petr (referee) ; Vaverka, Jiří (advisor)
The bachelor's thesis focuses on the calculation of stress arising from the loading of an open or closed eye bolts. The first part of the thesis provides an overview of eye bolts, their uses, and their differences. It also describes the theoretical background necessary for correctly solving the tasks in the second part of the thesis. The second part presents a total of four examples of stress calculations. The first two examples are solved for an open eye bolts, and the last two for a closed eye bolt. For each type of eye, two examples are solved: one task for axial loading and one task for loading perpendicular to the bolt's axis. Each task includes an analysis of the example and determination of the internal stress resultants (ISR). From the knowledge of the ISR, the critical point is found, and the maximum stress is determined, first using the theory of straight beams and then the theory of curved beams. Additionally, the safety factor is calculated using each maximum stress. At the end of each example, an analysis is also performed using the numerical method in the ANSYS Workbench software. Finally, a comparison is made between the results from the analytical calculation and those from the ANSYS software.

Deployment of new versions of GNOME project
Pekník, Štefan ; Kolář, Dušan (referee) ; Křivka, Zbyněk (advisor)
Cílem této práce je modernizovat a automatizovat proces vydávání nových verzí projektů a aplikací GNOME. Díky integraci GitLab Continuous Integration (CI) pipelines a dedikovaného API se výrazně snižuje potřeba manuálního zásahu do vydávacího procesu. Výsledkem je nový pracovní postup, který je efektivnější, rychlejší a méně náchylný k chybám. Práce analyzuje aktuální skript ftpadmin, identifikuje oblasti ke zlepšení a navrhuje řešení založené na API jako jeho náhradu, které umožňuje kontrolovaný a automatizovaný proces vydávání prostřednictvím GitLab CI. Navrhované řešení nejen připravuje půdu pro budoucí zlepšení řízení vydávání GNOME, ale také může sloužit jako model pro ostatní projekty, které usilují o zefektivnění svých vydávacích procesů.
