From a Dumb Boiler to a Smart One Using a Smart Socket
Mitura, Jacek ; Zemčík, Pavel (referee) ; Materna, Zdeněk (advisor)
Nowadays, the world of smart devices is growing very fast. Nevertheless, it remains difficult to acquire smart device for water heating applications. The usual reasons complicating this fact include the lack of the possibility of connection to the central control unit, or the need to replace the entire boiler with a new smart model. In both cases, the additional disadvantage is the higher price of such a solution. Therefore, the aim of this bachelor's thesis is to create a comprehensive and affordable solution, ensuring the conversion of an existing boiler to smart using a smart socket and a central server controlling the household. The solution uses a daily consumption forecast based on an exponential moving average to save electricity.

Smart Home Solution Based on ESP Modules and Raspberry Pi
Bartoš, Martin ; Smrčka, Aleš (referee) ; Janoušek, Vladimír (advisor)
Nowadays, the world of smart devices in households is growing significantly, where the devices communicate with each other and make people's lives easier. However, a major problem with the purchase of these devices to common households is the high price and compatibility of those products from one vendor. The goal of this bachelor thesis is to create a comprehensive low-cost smart home solution that the user will be able to manage without much effort. This solution is implemented by the latest technologies and tools.

Web Visualization of Smart Devices Data in IoT
John, Petr ; Burget, Radek (referee) ; Hynek, Jiří (advisor)
Due to the constant growth in the count of smart devices the need to store, aggregate and process the data effectively rises. The gathered data needs to be displayed effectively to the user, who will be able to react to the current state of the monitored device. This master's thesis deals with storing the data and displaying them using dashboards. The goal of this thesis was the creation of a library composed of components intended for data visualization and a simple API application, that can store and query the data effectively. The library is introduced in a simple application that uses the API application. Some parts of this solution are currently used in the company Logimic, where the costs of the database system reduced to 15 % of the average cost of the previous database system in the last 2 months. The rest of the solution is currently being integrated into the existing systems of the company.

Spotřební chování v oblasti m-commerce
Křivák, Martin
Křivák, M. Consumer behaviour in m-commerce. Diploma thesis. Brno: Mendel University, 2023 The thesis deals with consumer behaviour in m-commerce (mobile com-merce). From primary research using a questionnaire survey, it is found that con-sumers perceive the biggest advantages of m-commerce as the ability to shop any-time, anywhere and convenience. On the other hand, they perceive difficult adapta-tion by older people and limited physical contact as the biggest disadvantages. The factors that most influence consumer behaviour are price, supply and availability and user-friendliness. It is also found that consumers mostly purchase goods or services from the following categories: food, beverages and pet food, clothing and accessories, and electronics. Using cluster analysis, consumers are divided into four segments and recommendations for retailers are identified for each segment.

Neinvazivní stanovení glykémie z fotopletysmografických signálů nasnímaných pomocí chytrých zařízení
Vargová, Enikö ; Němcová, Andrea
Tento příspěvek se zabývá možnostmi neinvazivního stanovení glykémie z fotopletysmografických (PPG) signálů nasnímaných pomocí chytrého náramku a chytrého telefonu. Byly navrženy a implementovány dvě metody pro klasifikaci glykémie do dvou skupin (nízká a vysoká glykémie). Byly také vytvořeny modely strojového učení pro predikci konkrétní hodnoty glykémie. Reference byla získána invazivním měřením glykémie pomocí glukometru. Nejlepších výsledků klasifikace PPG záznamů do dvou skupin dosahuje metoda náhodný les (RF) a metoda podpůrných vektorů (SVM) s rbf jádrem. Zmíněné modely dosahují přesnosti na testovací sadě dat z chytrého náramku Acc = 76 % (SVM) a Acc = 75 % (RF). Ověření funkčnosti navržených modelů bylo následně provedeno na testovací sadě dat z chytrého telefonu, kde oba modely dosahují obdobných výsledků: Acc = 74 % (SVM) a Acc = 75 % (RF). Konkrétní hodnotu glykémie nejlépe predikoval RF pro regresi, který dosahuje průměrné absolutní chyby MAE = 1,25 mmol/l na testovací sadě dat z chytrého náramku a MAE = 1,37 mmol/l na testovací sadě dat z chytrého telefonu.

Web Visualization of Quality Control Data from Industrial Devices
Kozhevnikov, Dmitrii ; Hynek, Jiří (referee) ; John, Petr (advisor)
Currently, each specialist is faced with a large amount of data, and his goal is to work with them as efficiently as possible, but there are not often platforms that are able to provide an effective display of information for each user and have the possibility of individual customization. This bachelor thesis deals with data storage and display using dashboards. The aim of the work was to design and create a dashboard for organizations focused on quality control, which will allow not only to effectively display the necessary data, but also provide the user with the opportunity to customize the displayed information depending on his requirements and tasks. Some parts of this solution were deployed by Sanezoo. The result of the work done is an application for data visualization, which provides the user with data in tables in a convenient form, and also allows you to create and edit charts that will be displayed on a special dashboard. The application has been tested both with the help of automatic tests and by real users. In the future, new options will be added according to the test feedback and the application will be integrated into the Sanezoo application.

Family house automation system
Heczko, Dominik ; Cejpek, Zdeněk (referee) ; Dosoudilová, Monika (advisor)
The thesis deals with the automation of a family house. After an introduction to different automation options, a system based on an open-source project Home Assistant is proposed. Commercially available devices are connected to this system to provide control of appropriate functions. For each device, the configuration procedure is described. Furthermore, a prototype of a smart lighting controller and a smart thermometer is designed and built.

Health assessment using smart devices
Vargová, Enikö ; Filipenská, Marina (referee) ; Němcová, Andrea (advisor)
This thesis deals with the possibilities of non-invasive determination of blood glucose from photoplethysmographic signals. Elevated blood sugar is often associated with disease called diabetes mellitus. Diabetes is one of the world’s major chronic diseases. Untreated diabetes is often a cause of death. The aim of the work is to propose methods for glycemic classification and prediction. Two datasets have been created by recording the PPG signals using two smart devices (a smart wristband and a smartphone), along with their blood glucose levels measured in an invasive way. The PPG signals were preprocessed, and suitable features were extracted from them. Various machine-learning models for glycemic classification and prediction were created.
