Texturní analýza snímků sítnice se zaměřením na detekci nervových vláken / Texture analysis of retinal images oriented towards detection of neronal fibre layerGazárek, Jiří January 2008 (has links)
The thesis is focused on detection of local disappearance of the neural layer on retina in fundus-camera images. The first chapter describes the human eye physiology, the glaucoma disease and the analyzed data. The second chapter compares four different approaches that should enable automatic detection of a possible damage to the retinal neural layer. These four approaches have been tested and evaluated; three of them showed an acceptable correlation with the medical expert conclusions – the directional spectral approach, the edge based approach and the difference local brightness. The last approch via local co-occurrence matrices has not turned out to be informative with the respect to the issue concerned. Then a program for the automatic detection of the nerve fibre layer loss areas has been designed, realized and evaluated. This task is solved in the last chapter. A relatively good agreement between the medical expert conclusions and the conclusions detected automatically by this program has been reached.

Integrované telekomunikační prostředí / Integrated telecommunication environmentTomeček, Jan January 2009 (has links)
The thesis described the proposal for a wireless network problems. There are recorded and compared the characteristics of different wireless technologies. The possibility of voice communication securing is outlined and solutions implemented in the form of ZRTP protocol. The requirements for quality of service are discussed and the solutions to this issue are proposed. Other chapters are devoted to the actual design of specific equipment, including antennas and advance resource. The whole network is practically implemented in the mountainous countryside of eastern Wallachia. In conclusion, this work is network mate in terms of QoS (quality of service) and tested in terms of prioritization of voice communication.

Modelování dielektrických směrových odbočnic / Dielectric directional coupler modelingŠikl, Tomáš January 2011 (has links)
Dielectric High-frequency transmission lines are natural alternative to the lines made of metal in term of low loss. These lines are mainly used in microwave techniques of measuring. The main object is to describe basic parameters of metal and dielectric transmission lines and their comparison. Next point is a basic overview of the excitation the lines from metal and it's application on dielectric transmission lines. Then make the simulation of microstrip directional couplers and coupler made by dielectric waveguides. The last point of work is construction these directional couplers and measuring their most important parameters.

Druhá etapa přeložky I/9 Dubice – Dolní Libchava / The second phase shifting I/9 Dubice - Dolni LibchavaBelda, Miroslav January 2013 (has links)
Master's thesis will deal with the second phase of shifting I/9 Dubice - Dolni Libchava passing west of the Ceska Lipa with an approximate length of 3 km stretch. Estimated start-up of this section is in 2014. This project should build on in the future by-pass Ceska Lipa and Novy Bor, which is currently without funds for implementation by 2025. Traffic load after completion of the by-pass should be approximately 16500 vehicles / 24 hours in 2030. The section is designed in the category S 9.5 with optional solving two major intersections. This thesis will focus on reducing the cost of construction of the section.

Západní obchvat Pelhřimova / Bypass Pelhřimov westDočkal, Pavel January 2015 (has links)
Final thesis deals with relocation of road I/34, specifically bypass Pelhřimov west. The crossing with roads I/19 and I/112 is solved by interchange roundabout in nothern part of bypass. Reason of construction is unification road I/34, which is a part of the international route E551, to category S11,5/70. The principal tasks was to keep it in the land use plan and the effort to maximize the alignment of volumes of earthworks.

Řízení inteligentních pohonů IclA s využitím sběrnice CAN / Control Design of Intelligent Integrated closed loop Actuator by force of CANŠkranc, Martin January 2009 (has links)
This diploma thesis deals with automatization technology by B&R Automation Company. CANopen protocol is used for communication and control design of actuator part of omni-directional mobile robot. The control algorithms are implemented for compact PLC automata X20 series. The PLC X20 communicates with PC by means of Ethernet TCP/IP protocol. There are four motion control patterns implemented. The robot uses three IclA D065 actuators. This research has been supported by the Czech Ministry of Education in the frame of MSM 0021630529 Research Intention Inteligent Systems in Automation.

Řízená krystalizace odlitků z hliníkových slitin ve skořepinových formách / Controled crystallisation of aluminium alloys castings poured in shell mouldsMašková, Lenka January 2010 (has links)
The aim of this thesis is to verify a possibility of controlling the crystallisation of aluminium alloys poured in shell moulds in order to achieve directional solidification. For this purpose, new cooling plant has been designed and fabricated. Several sample castings were produced under different initial conditions. Based on the evaluation of measured temperatures, a numerical simulation of heat transfer was created using the ProCAST software. Finally, the sample castings were sectioned into specimens that were, subsequently, metallographically polished and the evaluation of their structure with respect to the amount and types of defects was performed.

Návrh řízení všesměrového mobilního robotu O3-X / Design of omni directional mobile robot (O3-X) controlOlša, Petr January 2010 (has links)
This thesis deals with the design of a three-wheeled omni-directional robot control. The model of control is designed for robot´s omni-directional platform driven by maxon motor with the intelligent positioning controller EPOS. The design of control contains: - installation of the coordinated systems and transformation from one of them into another - design of system´s kinematical model - creation of classes for control and communication with EPOS - creation of the simulative program - planning of the mobile robot´s path - verification that the system is working The solution was based on continuous accelerated motion and the maximal acceleration of wheels was concerned, so that the slip would be suppressed. The function of the model was partly verified.

Moderní techniky realistického osvětlení v reálném čase / Modern Methods of Realistic Lighting in Real TimeSzentandrási, István January 2011 (has links)
Fyzikálně přijatelné osvětlení v reálném čase je často dosaženo použitím aproximací. Současné metody často aproximují globální osvětlení v prostoru obrazu s využitím schopností moderních grafických karet. Dva techniky z této kategorie, screen-space ambient occlusion a screen-space directional occlusion jsou popsány detailněji v této práci. Screen-space directional occlusion je zobecněná verze screen-space ambient occlusion s podporou jednoho difúzního odrazu a závislostí na směrové informaci světla. Hlavním cílem projektu bylo experimentování s těmito metodami. Pro uniformní distribuci náhodných vzorek pro obě metody byla použita Halton sekvence. Pro potlačení šumu je použita bilaterální filtrace, která bere do úvahy geometrické vlastnosti scény. Metody jsou dál zrychleny použitím nižších rozlišení pro výpočet. Rekonstrukce výsledků do původní velikosti pro vytvoření konečného obrazu je realizována pomoci joint bilateral upsamplingu. Kromě metod globálního osvětlení byly v práci použity aj metody pro mapování stínů a HDR osvětlení.
