This bachelor thesis deals with the topic of smart flowerpots. The work analyzes supported plants and academic and market-based production solutions that are related to automation or some kind of improvement of the plant growing process. The analytical part describes the selection of production samples, which are selected for testing and collection of production data during experimental cultivation. The practical part describes not only the assembly of the measuring device, which performs data collection, but also the architecture of the backend and frontend of the web application, where the operational data from the measuring device is recorded. In the same part, the measured values are discussed and analyzed, and the values of two different production flowerpots are compared on the charts, which are a result of the frontend of the web application. The main benefit of this work is the created measuring software and hardware, which can be used in the future as a basis for a prototype of a faculty smart flower pot. Another benefit is the data itself, measured during the experiment, which determines the rate for future testing of the faculty prototype. Finally, the quality of the used production samples is discussed and the possibilities of reusing the measuring device are developed. In the appendix it is then possible to change the source codes of the application and images from the cultivation experiment.

This work aims to create a SMART security system for wine cellars, or other objects. The work is mainly focusing on wireless data transfer between the control unit and individual sensors. Furthermore, the for examines the ways of securing communication. The security system is expandable with additional sensors and provides a possibility with connection to a higher control unit. For this, Raspberry Pi 3B + is used as a control unit and ESP32 modules for wireless communication. Since control unit is Raspberry Pi, which also is capable handling higher programming languages, it is using a script written in Python. The reason is simple usage of this language and there are many public libraries. Furthermore, there will be sensors providing all the data like motion sensors, cameras or gas sensors. After this the control unit evaluates incoming messages and eventually alert the owner about system status. There are other examples of extending the system by SMART elements that are not primarily defined by the assignment. The work is mainly interested in data transfer. The result is robust SMART system that can monitor the premises using camera and inform the owner in the event of unauthorized intrusion. It is also able to monitor other potentially interesting data for system owner.

This bachelor thesis deals with the design and implementation of a functional prototype of a smart mirror. The analytical part of this work is devoted to a detailed analysis of already completed projects, whether by technology enthusiasts or products available on the market. The possible benefits or negatives of the investigated solutions are evaluated in this analytical part of work, either from the point of view of the materials used, technologies or the way of user control. In the next phase of the analytical part, possible SW platforms and HW products are considered, which could be used for the implementation of a smart mirror. Great attention is paid especially to the selection of suitable display components - various types of glasses and displays are discussed here. The practical part of this work deals with the creation of a functional prototype of a smart mirror. The construction of the mirror is unique, frameless and is designed to offer the user the largest possible display area for information and at the same time a modern design with voice control. The created prototype is based on the Raspberry Pi platform, and also are listed here expandable modules for light control. The steps for installing the individual SW platforms HomeAsistant, MagicMirror^2 and the voice assistant Kalliope are described. Part of the work is also a procedure how to configure individual platforms, solve possible problems and also it is indicated the way of possible expansion or use of the designed mirror in a smart home.

The goal of this work was to design a web application which would enable the development of Hierarchical Dependability Models (HDM). Although these models represent an efficient tool for system reliability prediction, they are still not supported enough. Our next task was to make a feasibility study of this application to appraise its benefits to technology-oriented companies and schools. It was carried out by evaluating the current state and comparing processes with our web application design. A good database and user roles design has been a crucial precondition for smooth teamwork which has led to higher efficiency. Well-designed and user-friendly GUI is another important aspect which makes working with the modeller easier and thus speeds up the process of development itself. Since the application is designed originally to develop HDM, unlike the others, it supports the automatization of many development processes. Combination of all these aspects provides a remarkable facilitation of HDM development, hence it fastens the system design.

The thesis focuses on the communication of the TPM security chip on the LPC bus. The aim is also to develop an FPGA design to capture this communication. In the theoretical part of the thesis, the structure of the TPM chip is described, and its most notable use cases are presented, along with basic information about the LPC bus. In the practical part, an FPGA design which filters only TPM related data from the LPC bus is developed. The data captured by tapping the LPC bus are then sent via the serial line and saved to a text file. Subsequently, the data are analyzed, and it is discovered that, when certain conditions are met, BitLocker Volume Master key can be found between the fetched data. This key can be used to decrypt the drive of the targeted machine. This way, an evil maid type attack is carried out. The attacker who got hold of a target machine can thus read previously encrypted data from the drive. The FPGA design is loaded into a physical board Basys3. Before connecting the FPGA to a real LPC bus, the design and implementation are tested, at first using simulation and after that, Arduino is utilized to mimic the behavior of an LPC bus.

This master's thesis provides a comprehensive analysis of the Robot Operating System (ROS) 2, including its architecture, communication patterns, concepts, and use of the Data Distribution Service (DDS) as a middleware for data sharing. Additionally, the thesis explores Micro-ROS, a lightweight version of ROS 2 designed to run on microcontrollers with limited resources. This work focuses on analyzing the Micro-ROS's architecture, features, and suitability for embedded systems use. Additionally, the thesis explores using PXROS-HR, a real-time operating system (RTOS), in the proposed solution. The proposed solution involves building a custom static library for Micro-ROS and implementing a mutex task for thread-safe data access. The project structure is presented, including configurations and linker files, and describes the implementation of custom allocators and custom transport for Micro-ROS. The thesis also includes demonstrations of multithread publisher-subscriber and multicore publisher-subscriber for Micro-ROS, showcasing the proposed solution's feasibility and effectiveness. Furthermore, the proposed solution is evaluated by conducting one test for each demo, including publishing and subscribing to a topic, creating a service server for remote procedures, and distributing work to multiple tasks or cores. The results demonstrate that the proposed solution achieves thread-safe data access and enables efficient communication in resource-constrained environments.

This work examines a newly developing industry in the Czech Republic called Agrivoltaics. The theoretical part of the thesis deals with the definition of terms related to the agrivoltaic industry. Furthermore, it describes the emergence of this phenomenon from the first idea to the current state (the State-of-the-Art), which is further analyzed in detail in this section from the point of view of usability, usefulness and, above all, the technological background that is needed for its realization. To narrow the scope, the work focuses only on agrivoltaic systems above vineyards, i.e. the collected metrics are set aside for this case. The practical part of the work includes the design and implementation of a simple monitoring system using modern IoT technologies in cooperation with cloud services. In the design part, the topology of the IoT network in the environment of the agrivoltaic system is solved. Possibilities of how to implement the network are stated and characterized in detail. Furthermore, suitable platforms for the monitoring system are determined here, including possible alternatives. The next step of the design is the selection of devices and modules that meet the requirements of the analysis of agrivoltaics over vineyards, for the implementation of the physical part of the monitoring system. Another practical part is the implementation of all the mentioned parts in the system design. The implementation describes the physical part of the monitoring system, its connection to cloud services and subsequently the configuration of individual services. All configurations are written in detail in the form of instructions that can be easily used. Part of the work is also the creation of a web interface for monitoring data, images and statistics of the monitored vineyard. The work ends with the implementation of the monitoring system prototype and the testing of functionalities in simulated conditions.
