Meassuring system for building constructions
Vladař, Martin ; Franek, Lešek (referee) ; Bradáč, Zdeněk (advisor)
This thesis deals with the measurement of physical quantities in building using decentralized system for data collecting. The system consists of Raspberry Pi as a master device of the system. There are three branches connected to this master device. Each branch consists of up to 32 modules for data-concentration from sensors of physical quantities. The Raspberry Pi has implemented web interface for displaying measured values and system administration.

Automatic calibration of inercial sensors
Hamada, Vladimír ; Vágner, Martin (referee) ; Macho, Tomáš (advisor)
The main aim of this thesis is to design and build automatic calibration system for inertial measurement sensors. The calibration system is intended to support the development of devices with inertial measurement sensors. The great emphasis is placed on the configurability of system and for this reason all calculations are realized by Matlab system, which is well known by engineers. There is also presented design of inertial measurement unit, which is used as a~model sensor unit for calibration system development.

Electronic geocaching
Pavel, Lukáš ; Babnič, Patrik (referee) ; Burda, Karel (advisor)
The goal is to design and implement a concept of electronic geocaching with contactless smart card and cell phone with NFC interface. In the first chapter I describe geocaching and try to familiarize the reader with this game. The second chapter deals with the issue of smart cards, I describe here the contact and contactless cards and their security. In the third chapter, I describe use and security of radio communication interface NFC. In the fourth chapter, I describe the principles of symmetric and asymmetric cryptography and selected cryptographic techniques. In the fifth chapter is description of proposed solution for electronic geocaching with digital signature. The last chapter describes all created applications.

Simulation model of waste collection for Network Simulator 3
Kolaja, Lukáš ; Mlýnek, Petr (referee) ; Fujdiak, Radek (advisor)
The goal of this diploma thesis is create an application for route optimalization for waste collection which is one of the technologies of smart cities. At first was described issue of smart cities focused to waste collection. The thesis describes the real deployment of smart waste collection using sensor network and was also designed its own model of smart waste collection. It is also described graph theory and related genetic algorithms which is suitable for waste collection optimalization. On that basics an application was made in C/C++ language which using a genetic algorithm to compute best possible path in graph which represents a map where waste is collected. By input data to application is vector image of evaluated graph in SVG data format.

Narrowband PLC communication based on G3-PLC, PRIME and IEEE-1901.2 standards
Skrášek, Tomáš ; Šilhavý, Pavel (referee) ; Mlýnek, Petr (advisor)
Diploma thesis is about narrowband PLC communication standards. The theoretical part describes details of all available OFDM standards including G3-PLC, PRIME, IEEE-1901.2 and G.hnem. The practical part deals with PRIME and G3-PLC standards. In this part is also compared OFDM technology with system of single carrier frequency in environment with real interferences. The last part describes developement of two firmwares for PLC modems Texas Instruments TMDSPLCKIT-V3, which allow UART communication and remote data collection. The thesis also includes Windows application developed to display and save collected data.

Methods for properties analysis of transmission lines
Žůrek, Dalibor ; Kočiš, Luboš (referee) ; Hadinec, Michal (advisor)
This work focuses on a search of available literature on the theory of transmission lines and verify the possibility of simulation processes on these lines using a suitable simulation program. Initially, for the introduction to the parameters and the phenomenon that characterize the line and are important for understanding the issue. These parameters are then measured and compared with traces from the simulation in program PSpice. In another part of the work, the reader is familiar with the basics of reflectometry and fault detection capabilities on transmission lines with the basic reflectometry methods TDR and FDR, as well as with other methods of OTDR, MSR, and PD-FDR. For the TDR, FDR and MSR methods were made experimental measurements with a view to determining the position of the various types of faults on the tested leadership.

Microcontroller programming in GNU/Linux
Jančík, Martin ; Frýza, Tomáš (referee) ; Fedra, Zbyněk (advisor)
This project is dealing with programming problems of the micro-controllers Atmel AVR in the system GNU/LINUX. It demonstrates wide programming possibilities micro-controllers of the system GNU/LINUX not only for the programming tasks, but for upload program to 8-bits controllers as well. The Project is aimed at the software, equipped with a graphic user´s interface, conceivably at a software enabling its control from a console. Further more, there are programming methods for the micro-controllers Atmel AVR described here, a survey of programs for micro-controllers AVR within the system LINUX is comprised there, as well as the proposal of some simple serviceable application using the micro-controller – displaying of the system information from a PC on an external LCD screen.

Design of Flow, Temperature and Pressure Measuring System
Macíček, Ondřej ; Čížek, Martin (referee) ; Sekora, Jiří (advisor)
This master’s thesis contains complete design of the complex measuring system for temperature, pressure and flow. Objects of measuring are pressure in rabbit’s heart ventricle, flow of the saline through the heart and the temperatures of physiological solution. Work is interested in programming of microcontroller and program for LabVIEW environment, which is used to view and export relevant data related to measuring. Text also contains technical documentation of functional sample of measuring system.
