RTP Protocol for Real-Time Data Distribution
Škarecký, Tomáš ; Kočí, Radek (referee) ; Hanáček, Petr (advisor)
This paper explores the potential of process data distribution in real time using the RTP protocol. Firstly, there is an evaluation of existing protocols that are used for this purpose. Secondly, there is a description of the trio of protocols RTP, RTCP, and RTSP, explained their functions and explored possibilities for their expansion. On the basis of this acquired knowledge, problems which may occur with the distribution of process data by means of RTP are identified and their possible solutions are proposed. To demonstrate the data distribution via RTP, the application, that collects GPS position from the PDA and then provides clients with them, has been designed and implemented. Clients can display these data on the map.

GPS Two-Stage Low Noise Amplifier
Šindler, Pavel ; Kasal, Miroslav (referee) ; Baran, Ondřej (advisor)
This work deals with a design of a low noise amplifier for the GPS band. The first part shortly describes properties of GPS signals and possible jamming sources. In the next chapter, basic parameters of low noise amplifiers, ways of the amplifier stability determination and stabilization are described. A summary of methods of a narrowband amplifier design follows. The next chapter contains a short description of filters usable in the designed amplifier. The next part deals with the design of the two-stage low noise amplifier with the help of Ansoft Designer software. The following part deals with the amplifier realization and its parameters measuring. At the end of this work, some experience with GPS signals reception with the realized low noise amplifier, a passive antenna and two different types of GPS receivers are mentioned.

Dualband Antenna for Global Navigation Satellite System
Mikulášek, Tomáš ; Lukeš, Zbyněk (referee) ; Láčík, Jaroslav (advisor)
This master’s thesis introduces to the reader with a modern antenna type the microstrip patch antennas. The most common types of microstrip antennas and their parameters and feeding methods are introduced in the theoretical section of this master’s thesis. This section deals with the circularly polarized microstrip antennas. Design of an active dual-band circularly polarized antenna for global navigation satellite application in the AWR Microwave Office is presented in the practical section. The proposed single-fed dual-band circularly polarized design is achieved using two stacked square microstrip patches. The antenna operates at the L1 + E1 and L5 + E5a frequency bands. Antenna preamplifier consists of a low-noise transistor and a dual-band band-pass filter. The thesis describes realization and measurement results of the dual-band antenna performance in the anechoic chamber. Measured results of the preamplifier performance are presented.

System for Management of Photographic Collections
Čermák, Pavel ; Juránková, Markéta (referee) ; Zemčík, Pavel (advisor)
This thesis deals with the management of digital photos by metadata contained in the photos. The thesis describes the structure of the formats JFIF, TIFF, RAW and EXIF format for storing metadata into photos. In the next part of this thesis is described the design and implementation of a simple photo management application. The main functionality of the application is focused on bulk editing EXIF metadata in the photos. In the conclusion of this thesis there's a proof of results and discussion about further extension options.

Augmented Reality for Mobile Devices for Local Visual Navigation for Android
Bezděk, Dušan ; Maršík, Lukáš (referee) ; Beran, Vítězslav (advisor)
This bachelor’s thesis deals with a proposal and implementation of application, that uses augmented reality and serves as a navigation for smartphones with the operating system Android. The navigation uses augmented reality for viewing virtual path into the canvas of the real world. This path is heading to the target destination. Map datas are provided by Google directions API and the location of device is fixed by GPS. This thesis describes a proposal and the realization of the application and writes about the solution of important problems in its implementation. The end of the thesis mentions the testing process and the final chapter evaluates the final results.

Search storage of fiber optic cables
Čučka, Milan ; Dostál, Otto (referee) ; Filka, Miloslav (advisor)
This work deals with the possibilities of laying and reverse lookup optical routes with the help of modern technology. Hereinafter, there are possibilities for documentation and registration of fiber optic lines. Speaking of thesis, it focuses on optical technology, advantages and disadvantages of this technology. Introduction focuses on fiber optic cable and related theoretical knowledge. Additionally, there are introduced comparisons with metallic lines. Another part is based on different searching methods for optical cables using metallic elements are analyzed in a detail. This section discusses galvanic and inductive methods. Subsequently, the thesis deals with searching for optical paths with the help of EMS (electronic marker system). Moreover, there are described individual types of electronic tags which are used in the installation of different kinds of lines. There are also briefly described seeker EMS markers, made by Dynatel. In addition to my work you can find the description of GPS (Global Positioning System) technology and routing the cable with the help of GPS system. Finally, possibility of documentation and evidence in the ArcGIS from ERSI and in the SPIDER-fiber from Gisoft is given. The overall functions of individual programs and their options are analyzed. The last section presents the implementation of laboratory tasks and programming burial markers, creating navigation in Urwigo and realisation with Openwing in Nokia phone. In the end of the work is map with markers positions.
