Sound emission directivity model
Zdvyhal, Marian ; Hájek, Roman (referee) ; Hejčík, Jiří (advisor)
This diploma thesis solves creation of a computing model of sound propagation for determination of acoustic pressure level around multiple point sound source with consideration of sound directivity of each source (compresor and fan). Thesis contains neccesary theoretical knowledge for creation of computing model and basics of sound measuring, theoretical computing model, measurement data of real unit and model configuration for real measured values. Computing code of the model in Visual Basic for MS Excel is a part of the thesis.

Gathering Wool
Švecová, Jana ; Petříček,, Miroslav (referee) ; Artamonov, Vasil (advisor)
The diploma thesis called "The Woolgathering" is connected with the idea of gather a wave. It is the image of vanishing moment, effort for hold something that escapes us. Practical part is represented by installation of text, image and audio based on experience, reflection and reverie.

Google Wave Technology
Michlík, Pavel ; Krček, Petr (referee) ; Poliščuk, Radek (advisor)
The Master’s thesis explains API and features of Google Wave technology, which was designed for flexible real-time collaboration of defined participants. The project aim was description of Google Wave basic elements and creation of sample Wave extensions, demonstrating capabilities of the communication protocol. The first extension (robot) was developed using client libraries in Java. The second extension (gadget) shows another approach of Google Wave extensions, based on XML, HTML, CSS and JavaScript.

Leisure time centre Brno - Brno reservoir
Novotný, Lukáš ; Velek, Jan (referee) ; Dulenčín, Juraj (advisor)
The proposed leisure center building Rowing Club bellows is located in southern part of the Brněnské přehrady between section Rakovec and Kozí horka. The building stands on existing club Lodní sporty Brno in the parcel čp. 1236. The idea of building is a ship sailing on the mainland, whose sails it look like waves. Student accommodation is designed to the second, third and fourth floor. Restaurant and administrative facilities connected to the terrace is designed in the basement. In the first underground floors are designed locker rooms, athletic facilities, kitchen and in the second underground floors is designed rowing pools and rowing boatyards connected to the ground. On the eastern side is a wooden rack tribune. Roads and pavements around the building are designed with simplicity and function.

Design of Communication system among Moving Vehicles
Klampár, Marián ; Polívka, Michal (referee) ; Škorpil, Vladislav (advisor)
The purpose of this thesis is to show up possibilities of inter-vehicle communication and to introduce new approaches in communication for the purpose of enhancing the security and the fluency of vehicle transportation. This thesis also highlights vulnerabilities in communication. The main goal is the analysis of existing technology and the design of protocol for data transfer with focus on minimizing handover time of informations. Part of the design is a simulation of communication based on acquired information.

Suppression of powerline interference in ECG signals
Lacko, Michal ; Hrubeš, Jan (referee) ; Kozumplík, Jiří (advisor)
This project includes survey of various methods ECG signal filtering, to suppress of powerline interference. It is specialized especially on properties which affecting the quality of filtration. The main essence of project is evaluation of the proposed methods in terms of quality and the least possible distortion of the resulting ECG signal. The work is focused on linear, adaptive filtering and filtering using discrete wavelet trans-form. Signal processing and evaluation of descriptive parameters are transferred using the graphical interface GUI in the program Matlab 7.7.0 ( R2008b ).

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.

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.
