Hypoglycaemia detection using smart devices
Stránský, Matyáš ; Vargová, Enikö (referee) ; Němcová, Andrea (advisor)
This work explores the possibility of using a smart device for hypoglycemia detection. Hypoglycemia is a dangerous condition in individuals with diabetes mellitus. The problem mainly occurs during sleep when a person is unable to react promptly. The aim of this study is to capture data to determine which symptoms (heart rate or electrodermal activity) are influenced by hypoglycemia. Data was collected during sleep using a smart device. Simultaneously, blood glucose levels were measured as a reference using a glucose monitoring sensor. The values were preprocessed, and subsequently, features were selected to identify hypoglycemia. Based on these selected features, a model for detecting hypoglycemia was created.

Intelligent Presence Detection
Kronika, Vojtěch ; Smrčka, Aleš (referee) ; Janoušek, Vladimír (advisor)
In this work I dealt with the solution of indoor localization, its design and implementation. We are at a time when the topic of smart home is a daily affair and the solution for indoor localization does not have a certain winner yet. The goal of this work is to create an intelligent presence detector, using Bluetooth technology, which recognizes in which room the device is located. And it estimates in which part of the room the device can be located. To achieve the goal, I use at least three sensors in each room and compare the signal strengths between the sensors and the localized device. A Kalman filter is used for a noise reduction on data signals from sensors. The result of the work is a functional solution for indoor localization. I have found that it is not easy to use rapidly changing signal strength within triangulation to obtain the exact position of the device. Further work could address what needs to be done to make triangulation possible and functional. One of possible directions is an exploration of Bluetooth Direction Finding technology.

Support for Codenames Game on Mobile Phone with OS Android
Grossmann, Jan ; Fajčík, Martin (referee) ; Smrž, Pavel (advisor)
This bachelor's thesis deals with creation of an application for support for the Codenames game on mobile phone with Android operating system. Application helps user with game strategy and simplify selection of the clue. First I discuss existing solutions and their imperfections. Based on this experience, I analyze designed solution and then, the very implementation with usage of Java programming language, involving storing data with database system or optical recognition. Finally, I undertake user testing, which I also describe in detail.

Energy Consumption of Smart Device in Smart Houses
Bína, Ondřej ; Pluskal, Jan (referee) ; Matoušek, Petr (advisor)
A large number of manufacturers are currently developing smart energy-saving devices, which should benefit not only with their available settings, but in many cases also save households on the consumption of water, gas, or electricity. This work focuses on verifying the electricity consumption of the most commonly used smart devices in the home that a person can purchase. The goal is to measure the consumption of these appliances in the home and subsequent analysis of the obtained data. As part of the analysis, the key findings are the comparison of the measured data with the data given by the manufacturer and with the consumption of their original "stupid" alternative. In addition to the mentioned analysis, the output of the work is also a recommendation of suitable device modes for specific use cases.

Mobile application for smart building components
Olenočin, Štefan ; Mikulášek, Michal (referee) ; Jablončík, Lukáš (advisor)
The bachelor thesis is devoted to the design of a mobile application for interaction with elements of smart buildings, focusing on biometric authentication. In the theoretical part, the thesis is devoted to general software design, specific platforms and software design using the Flutter framework are approached. Furthermore, the thesis focuses on REST API technology, biometric systems, their structure, advantages, disadvantages and discusses in more detail some biometric methods used in mobile applications. At the end of the theoretical part, the thesis is devoted to the analysis of available solutions and their comparison. At the beginning of the practical part, proposals are made for the principles of access rights using the Thingsboard service, which is also explained. The key processes in the application are explained below. At the end of the work there is a description of the application itself and its functionality.

Competitiveness based on the Internet of Things
SOVOVÁ, Kristýna
This Bachelor's thesis focuses on a new phenomenon, which is Internet of Things and its competitiveness in various fields, for instance health care, smart cities, smart homes etc. The aim of the thesis was to analyze the possibilities and use of IoT, its commercial use and the assessment of strong and weak points of this technology. The first part of the thesis focuses on Industry 4.0 and competitiveness, as well as Internet of Things, its history and relevant risks. The second part deals with the application of IoT in various areas, for instance industrial or consumer's IoT. The technology also focuses on European countries when it comes to commercial use. There will be an assessment of strong and weak points of this technology. The last part uses AHP method to analyze competitive advantage in four sectors, along with other methods, such as return on investments, net present value etc.

Arduino Based AC Wattmeter
Radvanský, Martin
This work deals with the design and manufacture of the AC wattmeter. It is controlled by the Arduino Nano and could be connected to 3 phase AC system. It is designed to be included in the DIN rail of the house central switchboard for monitoring of power consumption. Device contains build–in RS 485 interface for connection to the smart house control system. The device is designed to use separate current and voltage transformers for safety reason.
