Voice-controlled app for capturing photos and clips
Jurčík, Adam Dalibor ; Španěl, Michal (referee) ; Herout, Adam (advisor)
The goal of this work is to create an application that solves the problems of video and photo recording while the same person is playing sports. These problems are, for example, the need to carry a remote control or the constant interruption of the activity due to manual activation. This is solvedby using voice control and keywords to trigger the taking of a photo. This paper discusses in detail how voice control can be implemented on Android operating system in Java programming language. It also includes an explanation of how to store these files and how to control hardware devices such as the camera. The thesis includes a more detailed description of two approaches to voice recognition and describes their functionality in different applications.

Application for managing FPGA cards
Ostrý, Pavel ; Ilgner, Petr (referee) ; Dobiáš, Patrik (advisor)
This bachelor's thesis focuses on the management of FPGA (Field Programmable Gate Array) cards within the context of the VUT FEKT school system. FPGA cards are devices that enable hardware programming using programmable logic circuits, which significantly enhances the efficiency of specific tasks that requires low latency and high data throughput. Despite the growing popularity of FPGA cards, there is no graphical applications, that would enable their management in school system enviroment. The aim of this thesis is to develop an application that enables configuration, monitoring, and control of FPGA cards through a graphical user interface. The thesis is divided into ten chapters, with the first five covering the theoretical part and the remaining five focusing on practical implementation. The theoretical part includes an introduction to FPGA cards, their comparison with other similar devices, a description of their programming, and an analysis of the requirements for the final application, followed by the selection of suitable tools. The practical part concentrates on the implementation of the user interface, code structure, and the description of individual program classes and functions. The result of the work is a graphical application that meets all specified requirements and enables configuration, monitoring, and control of FPGA cards within the VUT FEKT environment. The application was developed in the Java programming language, with the graphical interface implemented using JavaFX. Communication with the FPGA card is handled using the libnfb library, which is written in C, with its functions mapped through JNA. This bachelor's thesis delivers an FPGA card management application developed based on the needs of VUT FEKT.

Practical Aspects of Reducing Technical Debt in Software Products
Hricovová, Alžbeta ; Janoušek, Vladimír (referee) ; Kočí, Radek (advisor)
This thesis focuses on practical aspects of reducing technical debt in software products, focusing on testing, refactoring, and continuous integration. Technical debt arises from compromises made during software development and, if unaddressed, can negatively impact the product and the company developing it. One of the solutions to reduce technical debt is continuous refactoring and code maintenance. This work describes identified violations of good object-oriented programming principles in the selected product and procedures applied to the product to mitigate the impact of its technical debt.

Comparator of Test Results
Čerbák, Patrik ; Kozák, David (referee) ; Smrčka, Aleš (advisor)
Tato bakalářská práce se zaobírá tématem testování OpenJDK ve firmě Red Hat a jak toto testování zefektivnit. Jeden z hlavních problémů při testování je porovnání, zda určitý test spadl pouze na jedné variantě testovací sady nebo na více variantách (jedna testovací sada se stejnými testy má mnoho variant – liší se například v operačních systémech, běhové architektuře, atd.). Kvůli tomuto je v této práci navrhnut a implementován nástroj pro porovnávání výsledků testů právě na odlišných varintách jedné testovací sady. Tento nástroj je implementován v programovacím jazyce Java a může běžet samostatně jako CLI program nebo ve speciálním webovém prostředí. Tento komparátor je zároveň součástí takzvaného Jtreg pluginu, což je open source rozšíření do nástroje Jenkins, které se používá v OpenJDK QA týmu firmy Red Hat. Samotný nástroj umožňuje spoustu věcí, například filtrování testovacích sad pro porovnání, vytvoření porovnávací tabulky spadlých testů, tabulky s podobností stack trace spadlých testů nebo třeba tabulky porovnávající výsledek sestavení jednotlivých testovacích sad.

Controlling Mobile App by Voice
Cologna, Adam ; Szőke, Igor (referee) ; Herout, Adam (advisor)
The aim of this bachelor's thesis is to explore, analyze, and compare available libraries for controlling mobile applications with voice commands. According to the thesis requirements, I solved the problem primarily for the Android operating system. I have considered not only libraries for keyword detection but also those using the speech recognition technology. For the selected libraries, I conducted accuracy testing for voice command detection and performance testing. To facilitate the integration of the chosen libraries, an application was developed in the modern programming language Kotlin using Jetpack Compose. The main contribution of this work is the experiments carried out and the resulting recommendations regarding the examined libraries. Among the most effective solutions were those from Microsoft Azure and the Android Speech Recognizer class. The main obstacles for each library were the distance between the speaker and the microphone, as well as distracting background music.

Development and testing of a module for HTTP/2 in the Apache JMeter program
Szymutko, Roman ; Martinásek, Zdeněk (referee) ; Šeda, Pavel (advisor)
This thesis focuses on the development of new modules for the software Apache JMeter. These modules implement an HTTP/2 protocol, which is not yet globally adopted. This means that it is not supported on all applications and servers, including Apache JMeter. These new modules add options for testing the new version of HTTP and are meant for simulating traffic on a server targeted by a Denial of Service attack. These modules allow an execution of an HTTP/2 flood attack and a Slow Read attack. The theoretical chapter of this thesis describes technical details about HTTP, JMeter principles, its alternatives, and also classical DoS and slow DoS attacks. The main advantage of Slow DoS attacks is low usage of network capacity for their function. Lastly in this text, there are also described two main components in depth: the newly developed modules and the web server used for testing the modules' functionality.

Integration of Web Data Sources to Information Systems
Hrubý, Erik ; Zaklová, Kristýna (referee) ; Burget, Radek (advisor)
The goal of this work is to create a library for the integration of data from web resources, such as HTML document, into information systems. The library is implemented in the Java language and the programmer will be able to use it for quick and easy mapping of data from the HTML document to Java data structures (objects), which he will be able to freely use in his information system operating on the Java platform. The programmer will be required to supply the library with his own implementation, in which the annotations will describe how the given values should be searched using the CSS selector or the XPath expression. The Jsoup library is used to download the web document.
