Compact Antenna System for Satellite Signals Reception in UHF Band
Lukáč, Vladimír ; Pítra, Kamil (referee) ; Urbanec, Tomáš (advisor)
Táto práca popisuje návrh anténnej rady pre príjem družicových signálov v UHF pásmu. V práci sú uvedné metódy získania informácií o družici a ich štatistikcé vyhodnotenie. Na základe získaných informácií sa navrhne vybraná antenna. Navrnutá jednoprvková anténa je simulovaná v programu HFSS Ansys. V simulácií sa berie ohľad na maximálny zisk, činiteľ odrazu a šírka pásma antény. Základný model a výsledky sú potom použité pre tvorbu anténneho poľa. Rovnakým spôsobom, anténne pole je testované v simulátoru ako jednoprvková antenna. Na základe simulácií, jednoprvková anténa je fyzicky vyrobené a odmerané. Získané výsledky z jednoprvkovej antény poslúžia ako základ pri vytváraní anténneho poľa.

Design of urban area using advanced technologies
Nováček, Michal ; Apeltauer, Tomáš (referee) ; Remeš, Josef (advisor)
The subject of the thesis is to define sunlight illumination as a building-influencing physical factor from the perspective of the technical standards in the Czech Republic. It aims to optimize the draft making process, and a quality of selected technical standards for sunlight illumination in the Czech Republic. In conclusion there is an example of a sunlight illumination analysis in different ways.

Automatic elevation and azimuth measurement system
Večeřa, Jindřich ; Kasal, Miroslav (referee) ; Záplata, Filip (advisor)
This bachelor´s thesis deals with an automatic elevation and azimuth measurement system, which will be used for antenna positioning. It is realized by using magnetometer and accelerometer. Important part of the system is tilt compensation and calibration for selected location. This system will send data to PC and also display them on LCD display. This project contains theory of measured quantities, method choice, component choice, realization of wiring, PCB design, programming device, testing device and accuracy determination.

Motion measurement by inertial sensors
Junasová, Veronika ; Šteffan, Pavel (referee) ; Levek, Vladimír (advisor)
This work deals with measuring specific types of movement in space using inertial sensors. It focuses on accelerometer, gyroscope and magnetometer. There is basic introduction to mentioned sensors, description of means of filtration their measurements and related mathematical part. The work contains design of board with selected sensors, description of sensors calibration, measurement of inclination and azimuth, optimalization of measurement, implementation of chosen filter. Functionality of measurement, calibration and filtration is demonstrated by results of measurement.

Electronic Compass Based on Three-Axis Magnetometer
Okoun, Petr ; Povalač, Aleš (referee) ; Šebesta, Jiří (advisor)
This semestral thesis deals with development of electronic compass with three-axis magnetometer which eliminates deficiencies of magnetic compass and then the developed device is usable anywhere at Earth's surface around the world. A compass is able to measure the azimuth only if its position is horizontal. Bearing in mind that this condition cannot be satisfied in any case, the solution of compass tilt compensation using accelerometer is part of the project.

Acoustic Signal Recording and Processing Using B-Format Technology
Kurc, David ; Balík, Miroslav (referee) ; Schimmel, Jiří (advisor)
This bachelor’s thesis is focused on the system of recording and processing of acoustics signals called Ambisonics. It describes single sections of this system in the chain of acoustic signal processing. At most it is aimed at the B-format technology as the main ambisonic instrument, its encoding from the signals recorded with the special microphone capsule of the soundfield type or with help of encoding equations and its decoding into single speaker channels of various speaker arrays. The UHJ transmission format is also mentioned. The application B-format Decoder was created in the MATLAB programming environment. It consists of several functions and has friendly user interface, which provides the processing and decoding of B-format components for the speaker array with entered parameters. Among others this interface ensures loading, displaying, analysis and playback of source and resulting acoustic signals.

Servomechanical movement control of photovoltaic panel
Uher, Ondřej ; Voldán, Jiří (referee) ; Němec, Zdeněk (advisor)
Thesis deals with the introduction to the production of electricity using photovoltaic panels and the relative position between panels and the Sun. The project aim was to design equipment to ensure the vertical position of the solar panels towards the Sun during the day so as to achieve maximum energy gain from sunlight. Pointing mechanism will be governed by the date and time.
