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.

Universal measuring device for USB interface
Nosek, Petr ; Šilhavý, Pavel (referee) ; Krajsa, Ondřej (advisor)
This bachelor’s thesis deals with design and subsequent implementation of Universal measuring boards, cooperating with the PC via USB, representing the office of the oscilloscope and logic analyzer. It contains a proposal for a hardware measuring boards and the proposal of operating software for microcontroller mounted on the measuring board, as well as for personal computer operating system MS Windows. The work is complete chart measuring the preparation, design printed circuit and the final product photos. We are also diagrams of all development programmes and their source codes.

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.

Position system design
Balogh, Jaroslav ; Čížek, Martin (referee) ; Čech, Petr (advisor)
The purpose of this diploma thesis was to explore possibilities, design and build 2D position system driven by PC via USB. ATmega16 and FT232R were used as the most important parts of hardware solution. Software for control of the position system was designed in C++ Builder and it can run under MS Windows XP. This work is based on semestral thesis and in future can be used in other applications or modified. 2D position system will be later used by UBMI in education and scientific applications.

Biological Signal Generator
Kadeřábek, Jan ; Čech, Petr (referee) ; Sekora, Jiří (advisor)
This semestral thesis describes signal EKG, it’s origin, evaluation and device for his generation. After identification with standard course of EKG signal, was such as signal created in program language Matlab. It’s consisting of 10 sinus courses, where each of them has it’s own frequence, start phase and amplitude. Each of this part of EKG signal is beat frequence variant. Rates of it’s durations and sizes were fixed from medicin literature. Such as created program were rewritten to program language C and is basic of main program, which control signal processor. Finally was propoused preparation, which will be generated this signal. Outcome of this thesis is teoretic treatise about signal EKG, created program for generation of this course include part control and machine doing realization of biological courses.
