Measurement of spray characteristics using optical measurement methods
Ďurdina, Lukáš ; Otáhal, Jan (referee) ; Jedelský, Jan (advisor)
Diplomová práce se zabývá měřením charakteristik sprejů dvou tlakových vířivých trysek pro spalovací komoru malého turbínového motoru na zkušebním stavu za studena pomocí metod Particle Image Velocimetry (PIV) a fázové Dopplerovské anemometrie (PDA). Cílem měření bylo stanovit a porovnat charakteristiky sprejů obou trysek. Výsledky měření mají objasnit rozdílnost chování trysek za provozu a možný dopad na proces spalování. Úvodní teoretická část pojednává o základních fyzikálních principech atomizace kapalin, konstrukci a oblasti uplatnění tlakových vířivých trysek a o principech laserových diagnostických metod použitých při experimentálním měření. Nasledující část popisuje návrh a montáž zkušební trati a dalších zařízení navržených pro experimentální měření v této práci. Experimentální část se zabývá nastavením parametrů měřícího systému a zpracováním dat. Výsledky měření zahrnují vektorová rychlostní pole, axiální rychlostní profily a distribuce velikosti kapek pro různé provozní podmínky obou trysek.

Application for PDA for multimedia stream presentation and processing
Javorček, Martin ; Číka, Petr (referee) ; Müller, Jakub (advisor)
This thesis deals with creating application for PDA for multimedia stream presentation and processing. Introduction of the thesis is devoted to the theoretical explanation of terms such as PDA (Personal Digital Assistant) and Windows Mobile 6.0. Readers will be acquainted with the technology of .NET Framework and also with its version for mobile equipment .NET Compact Framework. Advantages as well as disadvantages of .NET technology are dealt with in this section together with the same phenomena of C# programming language, which is the basic language used for running our application. Next chapters of the thesis deal with my own design of multimedia application, especially from the point of view of classes. For better orientation and understanding UML diagram is used. UML (Unified Modeling Language) is a graphic language intended for visualization and documentation of programming systems. Except of general description of the classes there is also a detailed explanation of individual attributes and application methods. Their function and purpose are explained here as well. In the next part of the thesis attention is paid to the network communication of the application, both in terms of individual multimedia files transmission and stream transmission. Principles of connection and disconnection between client and server are analyzed in this part. Client’ s part of the application is designed for the mobile equipment with Microsoft Windows Mobile 6.0 operation system and server’s part of application is designed for computers, where Microsoft Windows XP operation system is installed. A concise manual for operating both the applications is included. This part also describes some exceptions which may occur in case of problems with connection. Last chapters describe synchronization of mobile equipment or emulator with a desktop computer and provide the reader with the summary of supported audio formats in multimedia application. All achieved results are summarized in the concluding part of the thesis.

PDA software for robot soccer
Uhlíř, Luděk ; Honzík, Petr (referee) ; Hrabec, Jakub (advisor)
Robotic soccer is a game like a real soccer but here the game is played by robots. The rules are the same, only there are few exceptions (foul, penalty kick, stalemate situation). Game is running without the human intervention. Just a human referee is supervising the game. Two teams are attending the game. Each of them has a control computer. The control computer is the brain of the game. It has a camera, it is making decisions for the next step of robots and sending them configuration data. The thesis deals with testing of communication interface and designs the new communication protocol for the next generation of the robots. The testing is provided by pocket pc Palm TX. It will send data over the Bluetooth interface to the control pc and will configure particular constants, like constants of PID regulator and an address of a robot. This will be provided by the IrDA interface.

Quality of fuel atomization from small pressure-swirl atomizers
Malý, Milan ; Broukal, Jakub (referee) ; Jedelský, Jan (advisor)
Tato bakalářská práce se zabývá měřením charakteristik spreje z tlakové vířívé trysky za použití fázového doplerovského analyzátoru. Cílem měření bylo stanovit a porovnat charakteristiky spreje za použití různých kapalin a různých režimů tlaků a rozhodnout, jestli je možné nahradit kerosin biopalivy z pohledu kvality atomizace. Teoretická část se zabývá základy rozpadu kapalin z tlakových vířivých trysek a principy laserové anemometrie. Experimentální část popisuje testovací trať, provozní podmínky a nastavení experimentu. Výsledy obsahují vizualizaci spreje, velikostní rozložení kapek uvnitř spreje, profily rychlosti a Sautrova středního průměru za použití různých provozních podmínek jako je různá vzdálenost od trysky, rozdílný vstupní tlak a různé kapaliny.

Mobile mapping via GPS, the data processing and visual processing in the OziExplorer programme.
LORENCOVÁ, Petra
The target of this thesis is data collection via pocket PC and GPS receiver, together with data processing and visualization in the OziExplorer programme. To the partial goals belongs the description of the specific parts of mobile mapping from the data collection to their visual processing in this programme. The mapping was done in the area of the national protected zone of the Boubín forest, located in the Bohemian Forest. Before the mapping, it was necessary to study the theory of the GPS system, pocket computer, OziExplorer programme and their practical usage including the operation of all the basic functions of the OziExplorer programme. The subsequent step was configuration of the measuring devices and preparation of the data for mapping. A very important part of the data preparation was a diligent calibration of scanned maps which was essential for reaching correct consecutive measurements. The data collection was done by a pocket computer ASUS A639 with an integrated GPS antenna, operation system Windows Mobile 5.0 CZ, and a PDA version of the programme OziExplorerCE. The data collected from the field work in the area of the national protected zone of the Boubín forest, where the measured route was the educational path called the Boubín forest, were processed in the PC programme OziExplorer. Some corrections were made and the final route was transformed to the 3D model via the programme OziExplorer3D. The result of the thesis is the description of the constituent stages of the mobile mapping from the preparation and the data collecting to the visual processing in the OziExplorer programme and 3D model of the relief of the Boubín forest.

PDA utilization
MÍKA, Roman
The focus of this thesis is concerns of "pocket computers" and thein use. Although pocket computers have become a standard and an Essentials part of daily life for many, many questions remain. Nearly everybody can probably imagine what they look like, however many are not sure as to how to use them and in what situations. This is exactly why I have chosen this topic for my thesis. Address the history and also description of pocket computers in the first chapter of my work. Additionally, I describe individual parts and their function in the second chapter and I discuss the "software" and related functions and use in the third. Furthermore,I have dedicated the fourth chapter to personal global positioning systems (GPS). Garmin products, including the use and functions of used software. In the last chapter I discuss specific examples of use of "pocket computers" in daily life as well as target populations using and benefiting from use of "pocket computers".
