To Dvur Kralove by train - Transfer Terminal in Dvur Kralove nad Labem
Juránek, Marek ; Svojanovský, Viktor (referee) ; Žalmanová, Petra (advisor)
The terminal is becoming a heart of traffic in Dvur Kralove nad Labem. Linking of train and bus transport is inspired by a shape of a “courtyard” - open space, that is surrounded by buildings. This is a stage where acts of transportation, meetings, happiness and worries take place every day. Space has been designed so people don’t only use it for a purpose of transport, but also to enjoy moments of free time. The appearance gives a futuristic impression, however respects city’s history and tries to enrich its surroundings, so it doesn’t become just another place where people like to spend their time. Although trains and buses enter terminal from 21st century, design respects also its history as well as surroundings and use a form and function to promote them. “courtyard” terminal is a place for meetings and goodbyes, where a time flows and journey to adventure begins.

Water world - spa Krnov
Janák, Lukáš ; Svatošová, Ivana (referee) ; Boháč, Ivo (advisor)
Diploma thesis is proposing a new desing of Baths for the city of Krnov. This task comes from official architectural competition and it was chosen because of previous experience with simillar projects in bachelor´s study program. The main goal is to create a whole new year-round area not only with swimming pool services, but also for entertainment, relaxation, and summer sport activities. The design respects the meander of the Opavice River and is using the current outside swimming pool as a starting compositional element. The basic idea is to create perspective axes which would connect the Krnov historical architecture landmarks of the city (Svatý Kopeček, the Pilgrimage Church of Our Lady of the Seven Sorrows in Civilina, Krnov Town Hall, Evangelical Church, St. Martin's Church and the Church of the Nativity of the Virgin Mary) with the proposal area. The fundumental idea is to guide these axes in such a way that they would line the mass of the existing healthy greenery, and simultaneously they are shaping the form of a new bath building. Bathing facilities are designed to communicate as much as possible with the waterfront and the adjacent land for sports and physical education. The shape of the wave allows for maximum supply of sunlight from the outside, while inside it helps to orientate within the space naturally and create optimal space for individual operations. The internal operation of the baths is divided into three basic zones - sports zone (swimming pool), sports and recreation zone (aquapark) and recreation and relaxation zone (SPA and wellness). The basic principle is the balance of mind and body, which, thanks to the structure of bathing operations is calming the mind and simultaneously physically burden the body in one direction and vice versa in the other. The result is a bathing complex focused mainly on swimming and sports activities which is reaction to its history. Other activities are indoor/outdoor sauna, whirlpool, massage, gym, aquapark, restaurant, accommodation, which serve visitors as one open compact space that they can walk through.

Acoustic Holography
Vacula, Jan ; Janoušek, Michal (referee) ; Prokop, Aleš (advisor)
This bachelor´s thesis is focused on description and process during contactless identification of sound source for near and far field. Principles of individual methods of acoustic holography are relatively shortly described and for details of this problem (on the level of algorithm of software equipment) you can see the references below thesis, which were the basic theory of my study. The introduction was conceived like description of “acoustics world”. You can find the basic information and principles about sound propagation in space and their mathematical contain at time. For this it was essential to define quantity and their units. Subsequently there is inventory of used sensors and their own construction for this measurement. Next chapter point to some techniques of acoustic holography used in practice. It includes mainly a method NAH (Nearfield Acoustical Holography) and SONAH (Statistically Optimised Nearfield Acoustical Holography) used for near-field. For reconstruction of far-field is shown principle of a method of Beamforming and manual measurement by intensity probe. The ending is focused on a concrete application these methods on combustion engines of cars.

WATER+TOWN AQUADOMOS river story
Toman, Ondřej ; Vágnerová, Lenka (referee) ; Poslušná, Iva (advisor)
The result of design is architectural and urban design of unused area in Brno - Pisárky. This area was own by Water works company Brno. The area is situated next to the river Svratka. New research, information and exhibition center is designed on this place. The whole design was created in the context of river Svratka. The building which was designed there is called Aquadomos. This building consists of free pavilions. Each has a different use. The middle one contains main entrance, multipurpose recture halls, exhibitions areas, cash desk, information point and cafe. The largest pavilion contains exhibition area which is devided into six parts. The smallest pavilion which is situated close to the river contains administration department and laboratories. The external form, shape of building, is inspirated by river, waves, shape of landscape. Park is designed in the rest of parcel. In the park there are terraces to the river for easy access closer to the river Svratka. One of the main idea was to bring life closer to the river, to rediscover river in the structure of Brno.

This thesis is devoted to study the possibility of solving a hardware MISO emulator for fading channels and design of experimental device. The theoretical part starts with the theory of propagation of electromagnetic waves in a different types of environment, follows the principles and phenomena describing the radiocommunication channels and gradually gets up to specific channel models used for planning radio links. The actual design study of emulator is based on theoretical knowledge mentioned in this thesis. The basic principle of each channel model and thus so the emulator for fading channels is Tapped Delay Line model. From the point of view of the peripheral emulator solutions are designed with two topology circuits, parallel and serial-parallel. Emulator control method, mechanical arrangement, selection of topology circuit, components selection, desing of the PCB and software design is also analyzed. The results of this thesis is prototype production of experimental device and final discussion about achieved requirements and tasks.
