Altitude control of flying robot
Palacký, Tomáš ; Šembera, Jaroslav (referee) ; Baránek, Radek (advisor)
This bachelor’s thesis deals firstly with design and construction of a device for testing of altitude control algorithms of a flying robot. Secondly with creating and testing of an altitude control algorithm in order to apply findings while creating a copter control system. Provided is a selection and analysis of used hardware and software components – microcontroller AVR ATmega, ultrasonic sensor, motor controller and also communication interfaces IC, USART and SPI. Also design and realization of electrical wiring, circuit board and mechanical structure is being described here. The next section includes creation of software for microcontroller and PC application. The altitude control algorithm is developed using a simulation, furthermore tested and tuned for desired behavior.

Module for verification of rotational position sensors
Krolák, David ; Růžek, Václav (referee) ; Dřínovský, Jiří (advisor)
This master‘s thesis deals with design and realisation of a control module for automated measurements of the modern contactless inductive position sensors by a mechanical rotational system consisting of a DC motor and an incremental quadrature encoder. The thesis presents methods of driving DC motor and recording of measured data by a microcontroller. The thesis presents a communication protocol between the control module and personal computer via USB interface. A part of this thesis is also to develop a control software and firmware, including the measurement and evaluation of properties of the control module.

Tool for Designing Procedural Textures
Číž, Miloslav ; Polok, Lukáš (referee) ; Milet, Tomáš (advisor)
This thesis deals with implementation of a program library for designing and generating two-dimensional procedural textures and its GUI supportive tool. Attention was paid to common methods as well as to other computer graphics areas with effort for modifying the algorithms in order to achieve unique results. An effective way of texture representation and its concrete implementation is also presented.

On-line annotation editor with audio visualization
Dorotovič, Viktor ; Herout, Adam (referee) ; Szőke, Igor (advisor)
The aim of this thesis is to create a web-based annotation editor, which displays the audio waveform alongside the transcribed text. A waveform viewer library was developed, which uses HTML5 canvas elements for rendering. The library allows scrolling and zooming of the waveform. Annotations are directly marked in the audio and the position of the transcribed text is synchronised with their location. The end goal is to replace an existing editor with the one being created. Therefore, a usability test was conducted to compare the two. The time needed to learn to use the application and to transcribe a short recording was reduced by 20%. The waveform viewer library was released under an open-source license.

C Language Compiler Back-End for PicoBlaze-6
Bříza, Martin ; Ďurfina, Lukáš (referee) ; Křivka, Zbyněk (advisor)
Tato práce řeší konstrukci zadní části kompilátoru jazyka C pro soft-core procesor PicoBlaze-6 od firmy Xilinx. K řešení tohoto problému bylo zvoleno užití projektu Small Device C Compiler coby přední části překladače. Vytvořené řešení poskytuje podporu volání ukazatelů na funkce a užití struktur. Hlavním přínosem této práce je přenesení pokročilých konstrukcí jazyka C na procesor PicoBlaze.

Extension of the Code Listener Infrastructure Adding C++ Support
Kašpar, David ; Peringer, Petr (referee) ; Dudka, Kamil (advisor)
V této práci je popisováno rozšíření infrastruktury Code Listener, kterou lze použít pro tvorbu nástrojů pro statickou analýzu programů, o podporu zpracování programovacího jazyka C++. Řešení představuje rozšíření pluginu Code Listener bez nutnosti jakékoliv modifikace v již existujících statických analyzátorech, které jsou na této infrastruktuře postaveny. Výsledkem této práce je přidání podpory pro zpracování základních konstrukcí jazyka C++, jako například jmenných prostorů, L-hodnotových referencí nebo tříd.Přínosem této práce je možnost ji dále použít jako odrazový bod pro implementaci zbývající podpory jazyka C++ pro infrastrukturu Code Listener.

Server Component of a Web Application for Instant Messaging with AJAX
Švirga, Václav ; Burget, Radek (referee) ; Bartík, Vladimír (advisor)
The subject of this thesis is to create a server component to an instant messaging web application. The theoretical part of the thesis describes common instant messaging services and technologies used for building web applications. The practical part of the thesis focuses on the design of the application architecture, the implementation and the connections between the components of the application via the API. The conclusion of the thesis covers evaluation of the application.

64kB Graphics Intro Based on Ray-Tracing
Marek, Tomáš ; Polok, Lukáš (referee) ; Herout, Adam (advisor)
This paper deals with issues of creating graphic demo. There are shown some methods by which it is possible to fit large models, music and other important things to the program sized at most 64kB. It also seeks for the most robust design of a freamework for creating 64kB demos which could be used in the future and easily extended to provide other functions. The final demo shows the implementation of algorithms described in this thesis.
