Research and Development of Communication Infrastructure for Q Sorting
Krajňák, Sebastián ; Beran, Vítězslav (referee) ; Herout, Adam (advisor)
V dynamickom prostredí spolupráce pri vývoji softvéru sa požiadavky na interakciu v reálnom čase a zefektívnenie procesov nasadenia stala nevyhnutnosťou. Táto práca sa zameria na vylepšenie aplikácie nášho kolegu Michala Janu o funkciu spolupráce v reálnom čase prostredníctvom WebSocket spojenia. Táto funkcia umožní viacerým používateľom spolupracovať na jednom Q-sorte. Okrem toho na zefektívnenie procesu softvérového projektu pre viacerých vývojárov, ktorého je táto práca súčasťou, nastavíme CI/CD postup využívajúci Dokcer kontajnery, Jenkins a nakoniec webový server Nginx používaný na hostovanie aplikácií každého vývojára.

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.

Autonomous Beehive
Václavič, Jiří ; Nosko, Svetozár (referee) ; Smrž, Pavel (advisor)
The aim of this work was to construct an electronically controlled beehive. A crucial element of the project was to conduct thorough research on existing IoT and other electronic solutions used in beekeeping. It was essential to analyze the available hardware and software technologies that could be applied to the given issue and select those most suitable for this purpose. Based on the acquired knowledge, individual parts of the beehive were designed and manufactured using a 3D printer. These parts were specially modified to enable the integration of various sensors. An integral part of the solution is also the ventilation system and the custom design of motorized beekeeping frames, which allow for automatic honey collection. Sensor outputs and other data needed to inform the beekeeper about the colony's status are displayed on a web server, to which they are sent via MQTT communication.

Design and fabrication of a device controlling the important parameters of the aquarium based on the selected microcontroller
Cagáň, Adam ; Levek, Vladimír (referee) ; Háze, Jiří (advisor)
This master’s thesis describes design of the system, which automatically regulates water temperature in aquarium and measures water hardness. There is performed thermal analysis of specific model of aquarium, which defines required heat power. Based on this power Peltier module and heat exchangers are selected, that are part of designed heat pump. Thesis describes design of control unit based on ESP32-S3 microcontroller and complementary power supply circuit for Peltier module and uninterruptible power supply for microcontroller. Subsequently, there is designed web user interface running on Raspberry Pi 4B, which allows user to change desired water temperature, lighting interval and display measured water parameters.

Framework for a Web Internet Service
Hájek, Filip ; Smrčka, Aleš (referee) ; Hrubý, Martin (advisor)
The goal of this thesis is to design and implement a containerized web service, which provides the ability to create and run users' tasks. The task is only an abstraction over some particular implementation of computation. The task runs as a Docker container. The thesis also implements user management and the method of running task charging. The system architecture consists of a REST API web server and a user web environment. Worker applications are an essential component of the system. They start user tasks assigned by the server. The system was implemented using the .NET 6 framework in programming language C#. The run of the service has been simulated in a Docker environment. The service integrates existing Auth0 and Google Cloud Storage services. The result is an internet service deployed on a public cloud server.

Simulation scenarios in NS2 demonstrating knowledge obtained in the MPKT course
Mašek, Jan ; Mlýnek, Petr (referee) ; Jeřábek, Jan (advisor)
The aim of the bachelor´s thesis is to develop simulation tasks for modeling of data networks. The tasks will be used in the course Modern communication technique (MKPT). The networks are simulated in the environment of Network Simulator 2 (NS2). A brief description of program environment NS2, as well as basics of Tcl language is mentioned in the introduction. Described is the possibility of simulation HTTP protocol in NS2 using OTcl PagePool classes. Totally six proposed tasks form the core of the thesis. The first task uses PagePool/Math and displays the simplest communication between client, server and cache. Next task uses PagePool/CompMath and it shows the communication between client, cache, Web server, FTP server and FTP client. The task, that uses PagePool/WebTraf class, simulates communication between two clients and three servers. The last three tasks are of different topologies and course of communication using PagePool/ProxyTrace. The exercises of this class are the most complicated and their input files allow defining whole communication. The outputs of exercises are given in graphs, log files of HTTP communication and the last task contains detailed instructions.

iOS Application for Festival Visitors
Menšík, Jan ; Polášek, Tomáš (referee) ; Bobák, Petr (advisor)
The aim of this thesis is to implement iOS application aggregating information about festivals to one place. Application should provide general overview about individual festival events and help users with time planning. Thesis is describing process of creation from user interface design and system architecture to implementation with final testing. The result is client-server application providing web interface to organizers for any kind of festival registration which is later available in the mobile application. Server is implemented in Django framework, client application in framework SwiftUI.
