Measuring and Data Logging of Air Parameters
Kaziměrčíková, Lada ; Králík, Martin (referee) ; Sekora, Jiří (advisor)
The goal of the Bachelor thesis is to design a device for measuring humidity, temperature and CO2 concentration with implemented data logging. The Raspberry Pi computer was chosen as the control unit for the design of the device with three sensors, DHT11 for measuring temperature and humidity, NDIR MH-Z16 for measuring the CO2 concentration and NOVA PM SDS011 for detection PM10 and PM2,5 particles. The measured data from the sensors are stored in the MySQL database and are displayed on the web using PHP scripts and active Javascript elements. The Bachelor thesis also focuses on the analysis of air quality and the substances contained in the air with presented research for sensors used for measuring the concentration of these substances.

Battery powered datalogger with CPU
Andrýs, Jiří ; Beran, Jan (referee) ; Bradáč, Zdeněk (advisor)
In this design are mentioned processes of power consumption reduction of battery-powered devices.Execution of a project is software SPI for MMC card and file system FAT16 without extension of VFAT (Virtual File Allocation Table) – LFN (Long File Names). Hardware design consists of boost power supply, linear stabilizer, external RTC (Real Time Clock), IRQ low power modul, interface for MMC (Multi Media Card) and circuits for RS-232, RS-485. There is either a design of analog measuring interface.

Data processing procedure applicable for visualisation of FM objects in GIS environment
Hájek, Filip ; Kolář, Jan (advisor) ; Štych, Přemysl (referee)
This diploma thesis deals with the use of geographic information systems in issue of facility management. Its purpose is to show the advantages of this connection, mostly the visualization and analytical capabilities of GIS. The general issues of facility management are described in the first part of the thesis - what it is about, what it brings, the most important definitions and standards are provided there. Then it continues with theory about connection with GIS and answers the question, why this cooperation is beneficial. It continues with description of importance of GIS during whole life circle of real estate. The chapter is concluded by definition of another powerful tool in FM - CAD/BIM. The fourth chapter discusses one of the important tasks of FM - passportization and its meaning. The last chapter before conclusion focuses on the practical part of thesis dealing with campus of the Czech Post in Malešice. Keywords: Facility management, GIS, passportization, visualization

Distributed P2P Data Backup System
Mészáros, István ; Herout, Adam (referee) ; Szőke, Igor (advisor)
Tato diplomová práce představuje model a prototyp kooperativního distributivního systému zálohování dat založeném na P2P komunikační síti. Návrh systému umožňuje uživatelům přispět svým lokálním volným místem na disku do systému výměnou za spolehlivé úložiště jejich dat u jiných uživatelů. Představené řešení se snaží splnit požadavky uživatelů na ukládání dat, zároveň však také řeší, jak se vypořádat s mírou nepředvídatelnosti uživatelů ohledně poskytování volného místa. To je prováděno dvěma způsoby - využitím Reed - Solomon kódů a zároveň také tím, že poskytuje možnost nastavení parametrů dostupnosti. Jedním z těchto parametrů je časový rozvrh, který značí, kdy uživatel může nabídnout předvídatelný přínos do systému. Druhý parametr se týká spolehlivosti konkrétního uživatele v rámci jeho slíbeného časového úseku. Systém je schopen najít synchronizaci ukládaných dat na základě těchto parametrů. Práce se zaměřuje rovněž na řešení zabezpečení systému proti širšímu spektru možných útoků. Hlavním cílem je publikovat koncept a prototyp. Jelikož se jedná o relativně nové řešení, je důležitá také zpětná vazba od široké veřejnosti, která může produkt používat. Právě jejich komentáře a připomínky jsou podnětem pro další vývoj systému.

Comparison of system capabilities of Teradata and Oracle
Mimra, Jonáš ; Palovská, Helena (advisor) ; Vedral, Jakub (referee)
In my work, I deal with two database systems, Oracle and Teradata. I compare differences in data storage and database architecture. My work examines the performance of both systems installed on one operating system. The analysis was based on the speed of data import and response on SQL queries such as SELECT, SELECT with JOIN and UPDATE. Based on the results of my measurements recommend which of these two systems suits best OLAP and which OLTP database data storage technology.
