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.

Cloud-Native Single Sign-On with OpenID Connect and Keycloak
Koval, Maksym ; Pavela, Jiří (referee) ; Malinka, Kamil (advisor)
Cílem této práce je prozkoumat principy protokolů OAuth 2.0 a OpenID Connect a vysvětlit, jak by tyto protokoly měly být implementovány v architektuře mikroslužeb. Jako demonstrační aplikace byly navrhnuty dva webové klienty Angular a dva servery Spring Boot. Práce také vysvětluje připojení Keycloak jako poskytovatele identit pro výše uvedené aplikace. Výsledkem je centralizované autentizace všech aplikací a implementace mechanismu jednotného přihlašování v cloudovém prostředí.

Portal of the universal access control protocol
Čepelák, Tomáš ; Ležák, Petr (referee) ; Burda, Karel (advisor)
The paper focuses on the issue of access control. It presents an universal bilateral protocol of access control of ACP. The paper describes the messages and its sequences that AC portals uses for communication. It describes the functions and features of the modules from which the portal is composed. The paper suggests the concept of a modular AC portal solutions including the design of basic modules. It also outlines possible test scenarios. Under this proposal is generated functional AC portal on the .NET Framework platform using the C\# programming language. The portal provides access to local assets or to the assets on other computers in the local network. Created application is tested according to the scenarios proposed in both the network version and the local version of the AC portal. Test results are objectively evaluated and commented.

Browser Game with Artificial Intelligence
Moravec, Michal ; Volf, Tomáš (referee) ; Bartík, Vladimír (advisor)
Thesis describes design and implementation of a web browser game, which can be played by multiple players via the internet. The main goal is to manage the economy, although players can cooperate (trading) or play against each other (battles). NoSQL database is used for persistent storage of progress, which is also described in the thesis. Apart from human players there are also agents/bots, which play the game autonomously via state machines generated by genetic algorithms. Paper describes design and functionality of either the genetic algorithms, but also the state machines.

Remote data downloading from automotive digital tachograph
Matoušek, Vojtěch ; Macho, Tomáš (referee) ; Petyovský, Petr (advisor)
Thesis deals with device firmware design located in lorry, which provides remote access to vehicle digital tachograph data according to valid EU legislation. The result of this work is a system, which downloads digital data from digital tachograph and save them on remote server. The system for remote data downloading from automotive digital tachograph consists of three kinds of applications: server application, user application and firmware for communication device. Communication between applications uses encrypted TCP connection and own special designed messages.

Solution of the authentification and authorization for wireless local networks
Čížek, Michal ; Pust, Radim (referee) ; Burda, Karel (advisor)
This thesis is about available priciples and methods of authentication and authorization in wireless local area networks. First part is about available methods of authentication with short description each of them and usage analysis for small and middle-sized wireless networks. There is a project of authentication and authorization for school wireless network of three access points in the second part of the thesis, including description of Mikrotik RouterOS configuration and FreeRadius configuration. In the end of the thesis there is a project tests and usage analysis.

Study of the chemical profile of wine of Riesling variety
Šumberová, Michaela ; Trachtová, Štěpánka (referee) ; Vítová, Eva (advisor)
This diploma thesis focuses on the chemical profile and authentication of the geographical origin of varietal wine Rhine Riesling obtained from 4 Moravian wine regions. In the experiment, 20 wine samples were analysed with 5 instrumental analytical methods – aromatic compounds were determined by HS-SPME-GC-MS, phenolic compounds by HPLC-MS, total phenolic content by MAS, and elemental analysis by ICP-OES and ICP-MS. In total 36 aromatic compounds were detected, from which 7 were varietal terpenes and 2 of them C13 norisoprenoids. The total phenolic content for the Rhine Riesling wine was measured in the concentration range of 174,22–380,96 mg·l-1. Gallic acid (0,41–34,99 mg·l-1), catechin (0,05–7,44 mg·l-1), epicatechin (0,03–4,14 mg·l-1), caffeic acid (0,14–2,05 mg·l-1), and coumaric acid (0,30–4,04 mg·l-1) were the specific measured phenolics. In total 18 elements were measured in Rhine Riesling wine, macroelements K > P > Mg > Ca > Na with concentrations above 10 mg·l-1, microelements Al > Fe > Zn > Mn > Sr > Cu in the concentration range 0,1–10 mg·l-1, and trace elements Ni > Cr > V > Pb > Mo > Co > Cd in the concentration 0,0001–1 mg·l-1. Potassium was the most abundant element (386,37 mg·l-1). The results were used for the parametric and nonparametric univariate analysis of variance (ANOVA) and multivariate principal component analysis (PCA). Ni60 (p = 0,0029), ethyl benzoate (p = 0,0060), and diethyl succinate (p = 0,0247) were statistically the most significant parameters influenced by the wine region for the significance level = 0,05. Out of the 57 measured variables 7 parameters were identified as statistically significant and used for PCA graphic representation of the samples. PCA results show, that the varietal wine’s origin can be authenticated by chosen chemical compounds and chemometric methods.
