Using smart watches and their functions to measure health parameters
Uher, Vojtěch ; Křivánková, Markéta (advisor) ; Mahrová, Andrea (referee)
Title: Utilization and preferences of smartwatches and their features for measuring health parameters in the adult population Objectives: The aim of this master's thesis is to analyze the utilization and preferences of smartwatches in the adult population and to examine their potential for measuring health parameters through a questionnaire survey. Methods: The research was conducted through a questionnaire survey. A questionnaire of our own design was utilized. Results: The average age of the respondents who filled out the questionnaire for this diploma thesis was 31.2 years. 63 out of 103 probands use smartwatches to monitor their health status, with the most frequently measured parameter being heart rate. All 63 respondents follow here. The most used function associated with physical activity is tracking the number of steps. 91 respondents are interested in this data. Factors such as quality, accuracy, and design play a key role when choosing a smartwatch. According to the respondents, the most used smartwatches are from Apple and Garmin. Apple Watch is used by 42% of probands and the Garmin brand by 26% of probands. Respondents often prefer the Apple brand for its compatibility with other devices, and Garmin for its high accuracy. Smartwatches also provide motivation for users to engage in...

Peer Analysis in the Cryptocurrency Networks
Jeřábek, Vladimír ; Grégr, Matěj (referee) ; Veselý, Vladimír (advisor)
The aim of this thesis is to create a tool that will collect relevant information about active nodes in a Bitcoin peer-to-peer network. We are able to collect important data for more detailed analysis by monitoring the behavior of individual nodes on the network . The proposed solution uses unmodified Bitcoin Core client, which connects to all reachable nodes on the network. The platform has modular design, which offers good scaling as well. Created BiNMo tool (Bitcoin Network Monitor) also employs simple visualization of gathered data. The correct functionality of the monitoring platform was verified in the real operation, where it was monitoring Bitcoin network for more than two months. During that time, BiNMon parsed over 12 TiB of network data and stored over 270 GiB of metadata about active nodes. The entire platform can be deployed within a few minutes, thanks to Docker containerization.

Training tracking using NFC technology
Blažík, Vojtěch ; Zachariášová, Marcela (referee) ; Strnadel, Josef (advisor)
This bachelor thesis describes the development of mobile application which uses NFC technology for training tracking and monitoring of gym equipment usage. The work summarizes the basic motivation and approaches to training and equipment tracking as well as NFC technology and mobile app development focused on the multiplatform framework Flutter. The resulting app is based on the client-server architecture with offline mode support and uses the identifiers of deployed NFC tags to identify the machine and exercises. The goal of this work is to show a functional system, which incorporates this technology in an unconventional way to achieve a higher user comfort.

Design and optimization of device for characterization and recycling of plastic radioactive waste
Hrbáček, Tomáš ; Vojáčková, Jitka (referee) ; Katovský, Karel (advisor)
This thesis focuses on the generation, management and monitoring of radioactive waste in nuclear power plants in the Czech Republic. After the Second World War, with the development of nuclear power and armaments, radioactive waste management became an important field. The main sources of waste are the nuclear fuel cycle and a variety of industrial, research and medical activities. This work focuses on the detection of gamma radiation on plastic foils that are used as protection during reactor maintenance shutdowns. The objective is to contribute to more efficient waste management and to promote the recycling of materials in nuclear power plants with the collaboration with the company MIFRE s.r.o.

Drones (UAVs) Used in the Commercial Sector
Roman, Maroš ; Krhutová, Milena (referee) ; Rujbrová, Šárka (advisor)
Cílem této bakalářské práce je poskytnout krátký přehled typů dronů v běžném provozu spolu s několika typy dronů ve fázi vývoje prototypu. Práce následně pokračuje výčtem použití dronů ve čtyřech hlavních odvětvích, mezi něž patří zemědělský sektor, který se týká používání dronů v zemědělství a manipulaci se zvířaty. Druhý sektor je průmyslový. Zde jsou drony popsány pro použití jako monitorovací zařízení a práce jde do podrobností o tom, jak mohou být drony použity v dopravním průmyslu. Třetí sektor je vědecký a týká se využití dronů v geologii, lesnictví, archeologii, biologii a meteorologii. Posledním sektorem, který je analyzován, je sektor zábavního průmyslu, v němž je popsáno použití dronů voblasti zábavy a osobního použití. Práce také uvádí některé z dalších specifických použití dronů, jako je územní plánování a reakce na katastrofy. Posledním tématem, kterým se práce zabývá, jsou různé otázky spojené s používáním dronů vkomerční sféře. Konkrétně se jedná o obavy o soukromí, technická omezení apřípady vpádů do vzdušného prostoru v důsledku nedostatečné vládní regulace.
