Mechanisms of QoS assurance in fixed, wireless and mobile data networks
Václavek, Radovan ; Novotný, Vít (referee) ; Molnár, Karol (advisor)
This bachelor´s thesis deals with mapping technologies and base parameters used to guarantee the quality of systems in the local area networks, including wireless and mobile ones. I have focused mainly on requests and classifications, which are typical for the types of networks on link layer. In Ethernet I focused on the gradual trends in the fore mentioned technologies and IEEE 802.1Q and connected IEEE 802.1p standards included. The next part describes the quality of systems in wireless nets in different types of environments and again uses given standards for quality of systems guarantee in 802.11e and connected 802.11a/b/g standards. The next part focuses on the latest generations of mobile nets, looking at the types and trends of the latest technologies. Here I draw from standard project 3GPP, which describes the problems with these technological developments. The next part focuses on WiMAX technologies. In the penultimate paragraph, the constituent network technologies are compared from the view of securing QoS and I propound possible ways of securing coversion of constituent technologies. The conclusion summarises all the technologies I have mentioned and the future trends including possible problems and challenges with these latest technologies.

Activation of retail centre
Šellongová, Slavka ; Matoušková, Petra (referee) ; Žalmanová, Petra (advisor)
(hyper- prefixoid? gr.? large, redundant, exaggerated) Shop fast. Shop efficiently. Close to. At the best price. Economically advantageous. Timesaving. Check-in and save time. Glory to the hypermarket. Finally, the effort to save time with shopping under one roof and the valuable idea of spending time with family or close friends somehow doesn't work. Trade and the market mean the movement of people, and it is not entirely possible for it to be marginalized. Because people are drawn where there are people, where there is business. Pulling from the city, the streets to closed worlds. To the boxes that are not interested in being part of the city. Except they still are. Even though they build a wall of parking spaces around them and operate on their island, they are still part of the city, although they do not want to see it. They are so looked at themselves that they also let people look only at themselves. Maybe they're just setting up a human mirror. What will be and what could be different in the future when looking for answers, what about empty spaces. How to answer it today. I come up with a specific example of a hyper-surplus-market in Bardejov, which remained after the departure of the Hypernova chain from the commercial market. The city lacks a hall that could be replaced by a sports hall deck. A hall where seniors would occasionally go to see their grandchildren's performances or where the petty bourgeoisie could enjoy and provoke the local amateur theatre. However, where teenagers would come to spend their free time even during a normal day, mothers would have a replacement for the park on cold days and people could find space to start their own business.

Audio D/A converter with external control using microcontroller
Špaček, Jan ; Stifter,, Jiří (referee) ; Kratochvíl, Tomáš (advisor)
This diploma thesis is devoted to the design of a laboratory measurement tool with DAC converter for audio and low frequency signals. In the introduction part a theoretical background of the ADC and DAC conversions are outlined. In the next chapters the technical solution of the laboratory converter is presented, including DAC with integrated circuit AD1852 and completed with digital audio receiver CS8416. This circuit secures compatibility with external audio devices with digital interfaces, like SPDIF or AES3. The digital receiver and audio DAC are added with serial communication interface for setup of the most audio and input parameters. This setup is operated by external microcontroller ATmega32 and original firmware. The thesis presents block diagram and schematic layout of the laboratory converter, including complete technical documentation for the construction and design.

Revitalization of Technical Museum Brno
Kinnert, Filip ; Zemánek, Václav (referee) ; Zemánková, Helena (advisor)
Museum is firstly a public building in the city. Although, most of the work of collection, conservation and restauration is being done behind a closed door, with the museum's significance and location it has a great importance by co-creating the city environment. Reviving of our defined project area is potentially a big step for reviving the whole suburb. Technical museum of Brno has relatively good position nearby the Technology park, but currently not using much of the potential. This project adsresses these posibilities and propose a urban solution for enrichment of the museum to become a full-blown place IN THE CITY, a place for meeting, passing through and stopping by.

Conversion of dormitory to hostel and new design of hotel, Tomioka Silk Mill, Japan
Brezovský, Jindřich ; Zemánek, Václav (referee) ; Zemánková, Helena (advisor)
Diploma thesis called “CONVERSION OF DORMITORY TO HOSTEL AND NEW DESIGN OF HOTEL, TOMIOKA SILK MILL JAPAN“ was elaborated according to the regulations in the form of architectural study. The topics of this thesis were two variants of possible conversion of accommodation for workwomen (dormitory). The partial assignment comprised solution to the arrangement of greenery in the atrium of the dormitory, and revitalization of plateau. The building is located in the premise of a former silk mill in the city Tomioka in the Gunma prefecture on the Honshu island in Japan. The conversion of the building for the novel purpose required replenishment of necessary facilities, and some building interventions to assure operation of the hostel. In both variants, partial adjustment of the original building was needed. However, all changes had to maintain proportions and volume of the building not to compromise the original concept of whole premise as well as the skyline of the city. The adjustments of the original building of dormitory consisted of a completion of the entrance portal including a foyer, and a reception with the base of operation. Large glass areas in combination with exposed concrete were used as construction materials. These materials were selected so that the new structures (monolithic ferroconcrete) are clearly distinguishable from original ones (wood). The Internal atrium was designed in the style of modern japan garden with various types of surfaces (vegetation – moss; mineral – gravel and stones). Variant 1 – the new constructions of the two facility buildings. Building A is washroom building, and building B is catering building with toilets. The volumes of individual objects were formed by simple prisms rotated by 30° a 60° against axis of dormitory. These volumes complied with dimensions of the original building. The building A protruded on the edge of the slope, and it was paneled with glass plates. The building B was glassed-in from the south, while the northern side was constructed from exposed concrete in a compact way. The building A was divided to two symmetric parts by a central wall for both structural and functional purposes. At the end of the building, there was an ofuro (swimming pool) providing views of the surrounding mountains. Typological solution of the building B included separate toilets with a mixed washroom, which were located in the northern part of the building. In the southern part, the space for catering was divided to an operational space, and a space for visitors by a dispensing counter. The building A was from reinforced concrete and was founded on the base plate. The central wall represented the main load-bearing structural element that prevents transverse breakage. The central wall was anchored into the ground with piles. The building B was also from reinforced concrete and was based on the strip foundations. Variant 2 – the extension was formed as a simple prism that complied with the rectangular system of the premise and dimensions of the original dormitory building. Employed materials of the new constructions were concrete and glass similarly to the other new extensions. To ensure intimate environment, the glass part of a façade was enclosed by a bamboo fence. This space was also used as a viewable green garden. The building was typologically divided to the parts for women and men. Both parts were equipped with ofuro. The building was monolithic ferroconcrete skeleton based on the footings.

Technology Power to X
Řezník, Dominik ; Baláš, Marek (referee) ; Kracík, Petr (advisor)
The bachelor thesis deals with technologies for the electricity storage based on its conversion into another form of energy ("Power to X"). It considers the possibility of their use for the storage of electricity generated by renewable energy sources, which should gradually replace conventional electricity production in coal-fired power plants. The first chapter of the thesis is devoted to the current and possible future state of the electricity sector in the Czech Republic and a description of selected electricity generation technologies. The second chapter contains a classification and description of technologies suitable for electricity storage – their functional principles, advantages and disadvantages or e.g. possibilities of further use of products obtained by means of conversions are included. In the third chapter, selected parameters of these technologies are illustratively compared in created graphs, each containing two parameters. The results of the comparison are then continuously discussed.
