Operator for MariaDB Galera Cluster in OpenShift
Javorský, Lukáš ; Malinka, Kamil (referee) ; Januš, Filip (advisor)
Hlavným cieľom bakalárskej práce je vytvoriť riadený systém databázových serverov, ktorý je schopný sa adaptovať a reagovať na ich aktuálne zaťaženie. Riešenie tohto problému nachádzame práve v najnovšej platforme, určenej pre riadenie a nasadenie OpenShift 4 postavenej na základoch softwaru Kubernetes. Použitím operátora ako mysle celého OpenShift clustra, zodpovedného za nasadenie, vyvažovanie záťaže, detekciu zlyhaní a zotavenie po zlyhaní MariaDB kontajneroch, môžeme zabezpečiť, že bude databáza bezproblémovo fungovať, dokonca aj pri najvyšších špičkách záťaže počas dňa. Na replikáciu medzi databázovými servermi sa využíva softvér Galera vo vnútri každého MariaDB servera, ktorý zabezpečuje konzistentný obsah.

Modification of assembly line for production of electromagnetically controlled pneumatic valves
Palacka, Martin ; Ripel, Tomáš (referee) ; Krejsa, Jiří (advisor)
This thesis deals with proposal of assembly line modification for production of electromagnetically controlled pneumatic valves. The beginning of this thesis is dedicated to the theoretical study the most common Poka-Yoke systems, which are used for mistake avoiding in assembly process. There is described analytical analysis FMEA, which is used for detection of weak place in process. The next chapter is focused on description of valves manufactured on this assembly line. Main part of thesis is dedicated to proposal for process modification and design solution with choosing of appropriate sensors for some operations. There are created documents as a flow-chart for control algorithm, FMEA and process flow-chart for proposal according to automotive standard and estimated budget with counted payback period for whole project in last part.

Process Automation in Design Sprint
Farkašová, Martina ; Hypský, Roman (referee) ; Kreslíková, Jitka (advisor)
The topic of the thesis is an automation of the processes that are considered an integral part of the Design sprint methodology. The proposed solution is based on the knowledge gained by participating in one of the design sprints at Kentico Software s.r.o. After analyzing the individual processes, the evaluation of customer feedback on the given prototype was chosen for automation. The created JavaScript solution performs text analysis of the feedback to help speed up its processing.

Modern trends in technical measurements
Kollmann, Ladislav ; Vojáček, Zdeněk (referee) ; Vdoleček, František (advisor)
Bachelor thesis is focused on modern trends in technical measurements. The first part is devoted to the measurement status in the technical practice, the trends of its development and some selected analysis of these trends. An emphasis is put on the efforts of objectification of the measurement process to eliminate a man influence on its results. The final section shows new approaches to measuring with the example, which is a measurement of length – one of the oldest metrological tasks in human history.

Detection of Subjects Presence in Protected Area
Múdry, Adam ; Vašíček, Zdeněk (referee) ; Šimek, Václav (advisor)
The aim of this thesis was to design and implement a system for detecting the presence of the subject in the protected area using the embedded platform ESP32. The proposed system is able to use several different sensors, allowing the detection of motion, sound, allowing to take photos, etc. The solution was also implemented with the help of the Raspberry Pi platform as a control server and optionally uses cloud services for greater deployment flexibility.

Porting Tang to OpenWRT
Dudlák, Tibor ; Polčák, Libor (referee) ; Lichtner, Ondrej (advisor)
Hlavným cieľom tejto práce je naportovať a zdokumentovať tento proces sprístupnenia serveru Tang na vstavané zariadenia typu WiFi smerovač, s plne modulárnym operačným systémom OpenWrt. Tým dosiahneme anonymnú správu šifrovacích kľúčov pre zabezpečené domáce siete a siete malých firiem. Preto táto práca popisuje problematiku šifrovania a jeho využitie na zabezpečenie pevného disku počítača. Oboznámuje čitateľa so štruktúrou šifrovaného diskového oddielu podľa LUKS špecifikácie, na operačných systémoch typu Linux. Práca rozoberá možnosti automatizácie odomykania šifrovaných diskov použitím externého servera, ktorý vstupuje do procesu ako tretia strana. Sú v nej popísané princípy serverov Key Escrow a Tang. Dosiahnutie hlavného cieľa je možné vďaka procesu portovania a krížovej kompilácie na platforme Linux. Práca obsahuje zdokumentovaný postup prispievania zmien a novo vytvorených balíkov pre OpenWrt do príslušných Open Source projektov.

Automated Extraction of Information from Emails
Kanda, Rastislav ; Zbořil, František (referee) ; Vídeňský, František (advisor)
The purpose of this thesis is to familiarize oneself with methodology of information extraction from text. On the basis of acquired knowledge, propose a design and implement a system, which should be capable of gathering information from email messages. Proposed system should help Kiwi.com s.r.o. with processing of incoming email messages from travel companies. In current situation it is possible to process those email messages automatically. However, to process those messages automatically, it is necessary to manually create a template suitable for extraction. Possible alteration could be algorithm ROBULA+, which can generate more robust XPath locator from given XPath locator. These locators should be more resistant to changes in the HTML structure. ROBULA+ algorithm is a central point of automated creation of templates suitable for parsing email messages. Implemented system can be qualified with satisfactory successivity (approximately 75%). This means that system is able to find reference to created reservation in three out of four cases.

Cloud Computing Application Design Patterns
Kolesár, Matej ; Burget, Radek (referee) ; Rychlý, Marek (advisor)
This thesis aims to demonstrate available cloud patterns which solve existing problems that are experienced in the cloud environment. Various cloud patterns are first analysed from a high-level view and then further studied on a lower component level. These components and architectures provide certain solutions depending on the use case of the application. A demo application is designed to showcase these design patterns and how they behave. The implementation is done using kubernetes and it is deployed to AWS. The chosen architecture uses microservices. The application consists of 2 designs. The first one shows the AWS advantages and the second one can be deployed on private clouds but also on AWS. At the end, experiments are performed that verify whether the used patterns had the expected results.

Test Suite of the EAS Framework
Mazáková, Júlia ; Janoušek, Vladimír (referee) ; Smrčka, Aleš (advisor)
Toto dielo sa zameriava na softvérové testovanie systému s dôrazom na nižšie vrstvy testovania, ktoré zahŕňajú testovanie jednotlivých komponent a integráciu. Hlavným cieľom je demonštrovať proces testovania na EAS (Efektívny Agendový Systém), začínajúc plánovaním testov a následne vytvorením konečnej testovacej sady, ktorá vyhodnocuje výkon mikroslužieb systému. Táto testovacia sada pokrýva významnú časť funkcionality systému. Výsledky sú zobrazené a analyzované vo vygenerovanej testovacej správe. Analyzovanie systému a konečný report slúžia ako cenný nástroj v rámci testovania.
