Natural Language Processing: Analysis of Information Technology Students’ Spoken Language
Stanković, Aleksandar ; Šťastná, Dagmar (oponent) ; Ellederová, Eva (vedoucí práce)
This bachelor’s thesis deals with the issue of new artificial intelligence technologies in natural language processing. The thesis consists of a theoretical part and an analytical part. The theoretical part approaches the issue by dividing it into three chapters: artificial intelligence and statistics, natural language processing, and IBM Watson Natural Language Understanding. Each of these chapters is elaborated on by using at least one example from the real world. In the first chapter, the main aim is to frame the theoretical framework of artificial intelligence and its practices, while in the second chapter, natural language processing and its primary functions are explained as well as its relation to artificial intelligence itself. The aim of the third chapter is to introduce natural language understanding as the primary tool for analysis which is done in the analytical part. The analytical part deals with the analysis of students’ spoken language using various methods. Collected video samples are transcribed by means of a machine translator as a natural language processing application, while the textual output is analysed through a natural language understanding engine. The applied knowledge from the theoretical part is used in the analytical part that includes the description of research methodology, presentation and interpretation of research results.

Application for OpenShift Plaform for Testing of Students Projects
Országh, Marián ; Janoušek, Vladimír (oponent) ; Smrčka, Aleš (vedoucí práce)
The aim of this thesis is to design a service for automated requirements-based testing of student programming assignments, and thereafter implement this service using the OpenShift, Python and Git technologies. By creating such a service, a foundation is set for a unified testing process, which includes executing the test suites in separate Linux containers. Such a process is intended for simplification of the grading by teachers and teacher assistants, and at the same time improvement of student's performance in such tasks. This Master's thesis explains the basics of software testing, while focusing on requirements-based testing specifically. Furthermore, it provides insight into the container technology, as well as how these themes are applied in the project's design, and how they are reflected in the service's requirements. Afterwards, the implementation details of the service are put under examination in order to provide a reference material for any future extensions of the project. The implemented service allows for basic operations, including testing of multiple student projects in separate containers concurrently, creating a containerized debugging session, or automatically building a testing container image for a given assignment.

Real Time Data Processing with Strimzi Project
Orsák, Maroš ; Malík, Viktor (oponent) ; Rogalewicz, Adam (vedoucí práce)
Container technologies become broadly used in modern times. In prevailing, applications made on the micro-service architecture are rising. This thesis analyzes the design of an application that will process data in real-time. Further, the application will be built using state-of-the-art technologies used by world companies like Netflix, Uber. They are using the systems for real-time data processing such as Apache Kafka, and in recent times they raised it on a higher level by encapsulating this system in the container environment, which guaranteeing effortless scalability. Additionally, using the latest native Kubernetes technologies for processing dozens of data with Quarkus and Strimzi. The problem, which arises, is that these types of real-time data processing systems encapsulated in the containers are especially challenging to test. The main goal of this thesis is a proof-of-concept application based on Strimzi project and also show the designed long term test of the application also known as Marathon, which is the ideal demonstration of user conditions.

Platforma pro virtualizaci komunikační infrastruktury
Stodůlka, Tomáš ; Martinásek, Zdeněk (oponent) ; Uher, Václav (vedoucí práce)
Diplomová práce se zabývá výběrem platformy pro virtualizaci infrastruktury se zaměřením na kontejnerizaci s podporou sandboxingu a následným zkoumáním její náročnosti. Práce začíná vysvětlením základních technologií jako: virtualizace, cloud computing a kontejnerizace spolu s jejími zástupci, kteří danou technologii zprostředkovávají. Zvláštní prostor je vymezen právě pro platformy cloud computingu: Kubernetes, OpenStack a OpenShift. Nejvhodnější platforma je pak vybrána a vlastním způsobem nasazena tak, aby splňovala veškeré podmínky stanovené vedoucím práce. V rámci testování náročnosti vybrané platformy jsou vytvořeny skripty (převážně v jazyce Bash) určené ke skenování vytíženosti systému, vytváření scénářů, simulaci zátěže a automatizaci.

Security mechanisms of OS Android utilizing the Kotlin language
Balaževič, Lukáš ; Mašek, Pavel (oponent) ; Zeman, Kryštof (vedoucí práce)
Mobile devices are a novelty in technological history. With technology that is evolving at such a rapid pace and growth in use, it is necessary to pay attention to security. This diploma thesis deals with the analysis of the security mechanisms used in the Android OS and the communication between the Android OS and the remote server. The aim is to examine these mechanisms and test which cryptographic methods and procedures are most advantageous in terms of security with regard to efficiency. This knowledge was used to create a demonstration system that uses selected security mechanisms and cryptographic methods.

Platforma pro interaktivní výstavy založené na aktuální poloze
Čonka, Filip ; Kreslíková, Jitka (oponent) ; Bartík, Vladimír (vedoucí práce)
Táto práca sa zaoberá tvorbou webovej aplikácie na zobrazovanie interaktívnych výstav založených na aktuálnej polohe v interiéroch. V práci predstavujem aplikáciu neviazanú na konkrétnu implementáciu zdroju zobrazovaných dát. Aplikácia využíva moderné technológie pre tvorbu dynamických webových aplikácií. V práci sa zaoberám aj problematikou nasadenia aplikácie s využitím cloud computing. Samotná implementácia aplikácie zahŕňa využitie JavaScript frameworku Vue.js, ako zdroj dát sa využíva REST API naprogramované v PHP s využitím Laravel Framework a October CMS. Na polohovanie v interiéroch využívam RTLS platformu spoločnosti Sewio. Aplikácia beží v prostredí Docker kontajnerov s využitím technológie Kubernetes pre orchestráciu týchto kontajnerov. V práci som vytvoril platformu, ktorá prináša do prostredia výstav interaktivitu a možnosť zobrazenia dodatočných informácií k vystavovaným exponátom. Na základoch tejto práce je možné nasadiť aplikáciu vo vybranej výstave, galérii, či múzeu a tým zvýšiť atraktivitu daného miesta.

Kubernetes Canary Deployment Controller
Malina, Peter ; Burget, Radek (oponent) ; Rychlý, Marek (vedoucí práce)
The need to deliver value to users sooner rises each year in the competitive IT market. Agility and DevOps are becoming critical aspects of software engineering, seeking tools to enable and improve agile culture. Software projects in such culture tend to deal with new deployment strategies to reduce the risk of new changes breaking the existing system. However, staging and test environments almost always differ from the production. Using the appropriate deployment strategy, such as the canary, improves the overall stability of the system by first testing the new changes on a small subset of production traffic. Multiple experiments were made to prove that canaries can positively enhance deployment stability and reduce the risk that new changes bring.

Modul MMO pro nasazení mikroslužeb do clusteru
Kulich, Jakub ; Beran, Vítězslav (oponent) ; Herout, Adam (vedoucí práce)
Aplikácie s architektúrou typu "mikroslužby" je náročné orchestrovať. Dostupné nástroje neumožňujú užívateľom nasadenie aplikácie bez veľkej znalosti cieľovej platformy. Ďalším problémom je, že užívatelia pri nepozornosti robia chyby pri používaní týchto nástrojov. Vývoj aplikácií s architektúrou typu "mikroslužby" zjednodušuje open-source nástroj MMO - Monorepo Microservice Orchestrator. Rozšírením tohto nástroja o určité časti nám umožňuje vyhnúť sa spomínaným problémom. Jedna časť slúži na generovanie konfigurácií pre nasadenie aplikácie do Kubernetes clustera. Druhá časť umožňuje samotné nasade- nie aplikácie do Kubernetes clustera. Výsledkom používania rozšírenia nástroja MMO je uľahčenie vytvárania konfiguračných súborov u začiatočníckych používateľov nástroja Ku- bernetes, urýchlenie vytvorenia konfiguračných súborov u pokročilých užívateľov nástroja Kubernetes a zníženie počtu chýb ktoré užívatelia robia pri ručnom nasadení aplikácie.
