Solar cooling system
Klusák, Jan ; Fortelný, Zdeněk (referee) ; Pospíšil, Jiří (advisor)
The work is focused on the issue of cold production using absorbent circulation driven by thermal energy solar collectors recovered. The work can be divided into several main parts. In the first part of this work is given an overview of the possible principles of solar cooling system. In the next section followed by a description of the principle of absorption cycles. In the practical part is solved design proposal absorption refrigeration units with a cooling power of 6 kW. This is followed by a proposal to link solar cooling system with the absorption unit. Final section is made of basic technical-economic comparison of solar refrigeration unit with the compressor refrigeration units.

Apartment building with cafe
Oujezdská, Lenka ; Pobucká, Slávka (referee) ; Utíkalová, Ivana (advisor)
The subject of the bachelor's thesis is the processing of documents and project documentation in the scope of PCB for an apartment building with a cafe with almost zero energy consumption. The apartment building will be located in the town of Slavkov u Brna, in the Zelnice II district. The project will address the layout of the apartment building, individual apartments and storage space for these apartments. Furthermore, the design of the foundation structure and ceiling structure of individual floors and the calculation of the staircase of individual floors will be processed. The design will also include a flat roof solution, structural composition and fire safety solutions.

Plagiarism Detection
Kobath, Martin ; Petyovský, Petr (referee) ; Honzík, Petr (advisor)
The Bachelor‘s thesis concentrates on plagiarism detection in written text, mainly final theses in author’s Alma mater. The current situation of automatic plagiarism detection of text in czech language is evaluated and a theoretic analysis directed on classic detection by finding matches in a text with use of external sources, mainly the internet, is made. Project ends with custom concept of automatic plagiarism detection system and with an experiment made on 100 randomly chosen theses from The Faculty of Electrical Engineering and Communication.

SLAVKOV - REVITALISATION OF BONAPARTE CENTER
Kousalová, Barbora ; Plášil, Jiří (referee) ; Boháč, Ivo (advisor)
The bachelor thesis deals with the design of a multifunctional complex consisting of the existing Bonaparte restaurant building and new outbuildings on the neighboring parcel located in Slavkov u Brna in the urban conservation area in the immediate vicinity of the castle grounds. The newly created complex provides the necessary missing public functions at the level of contemporary standards. It offers an answer to the concept of neoplasm in the historical environment and its interaction in the context of the second part - a reconstructed historical building. The multifunctional complex of both buildings should provide classrooms for elementary art school, restaurant, social hall, library, information center, public toilet, seniors / youth club or maternity center, polyfunctional spaces for rent, spaces for dental surgery.

Jaroslavice – place in the landscape
Dočekalová, Veronika ; Eichlerová, Eva (referee) ; Ponešová, Barbora (advisor)
The aim of this thesis is to design improvements to increase the quality of the living in the territory of Jaroslavice and its surroundings. This South Moravian rural area located near the Austria–Czech Republic border may currently be considered as a No man's land. Given the subject of the thesis, the author suggests the conceptual solution of this problem. Focusing on the life in a border region analyses offer of the local development, amenities and opportunities, not forgetting about the education. The work suggests an entirely new local education system from the very beginning - from kindergartens to secondary education. The missing high school forces students to travel or to move to nearby towns such as Znojmo. what usually leads to their breakaway from the local environment. This could be avoided by building a new secondary school in Jaroslavice. It would link to the rich history of this village from the pre-war period, when it was considered an important transition point between the cities of Brno and Vienna. Besides, Czech-German school can re-establish mutual cooperation between both countries. Designated school is based on a current education needs, e.g. practical training experiences in local businesses, which is costs saving and immediately applicable. The subject of this thesis is placed into the area of the ruined mansion under the local castle. Besides school, there is also Food Center and Research Institute. All three institutions cooperate together, similarly to the concept of manor court (meierhof) in the past. Educational facilities are arranged in U-shape form with the inner courtyard and the large greenhouse on one side. Each wing of the building is self-sufficient and has a different character. The west wing is two-storey, on the ground floor there is a library with classrooms for social sciences and the heart of the house - room for theatre and performances. On the second floor there is a school headquarters facing the courtyard with the ability to check the daily routine. The central wing with entrance consists of classrooms of natural sciences and another social science classrooms located towards the courtyard for eventual outdoor lessons. Last part consists of computer classrooms made for the technical sciences. This wing leads to the lower floor with side entrance to a parking lot. Greenhouse, designed for both the public and the students, is an inseparable part of the school.

Bucket hoist for food grain transport
Šustek, David ; Pokorný, Prokop (referee) ; Škopán, Miroslav (advisor)
The aim of this thesis is a construction solution of a bucket elevator for transportation of grain with specifiedtransport quantity and specified transport height. In the first part of the thesis, a brief overview of individual parts of the bucket elevator and their influence on the function of the devicewas performed. The conveyor parameters are then determined based on the overview. The second part of this work focuses on the theoretical calculations. Using these calculations, the individual components of the bucket elevator are selected or designed. This part includes a control of the safety of the drive shaft, together with the subsequent calculation of the bearing durability. This thesis further comprisesa relevant drawing documentation of the whole bucket elevator assembly and the subassembly of the driving station.

Analysis of model operation of multi-degree-of-freedom energy harvester
Witassek, Tomáš ; Rubeš, Ondřej (referee) ; Hadaš, Zdeněk (advisor)
The first part of this bachelor’s thesis is an overview of vibration energy harversters with multiple degrees of freedom. Several options of broadening the usefull frequency bandwidth thanks to multiple degrees of freedom are described in the overview. The following part is a model in Matlab & Simulink analyzing behaviour of a vibration-powered generator with a harmonic excitation and another one with a real excitation. The main focus is on the output electrical power and energy in relation to geometrical parameters and electromagnetic damping.

Design of metasurfaces for advanced optical elements
Březina, Tomáš ; Kvapil, Michal (referee) ; Hrtoň, Martin (advisor)
Metasurfaces represent an intriguing class of materials with a wide range of promising applications, one of them being advanced planar optical elements for industrial production and imaging. The main goal of this thesis is to design such an optical element, namely a beam-shaper consisting of dielectric anostructures in HCTA (high constrast transmitarray) arrangement. The first part of this work introduces a simplified theoretical model of the optical response of building blocks that facilitates understanding of the basic functional mechanism behind the phase metasurfaces. To quantify the optical response of dielectric building blocks with enough precision, numerical FDTD simulations were employed. As a result, a database compatible with lithographic fabrication procedures was created. To find the phase distribution ensuring the desired beam-shaping function, two approaches were investigated and implemented: the semi-analytical method of geometric transformation and the iterative Gerchberg-Saxton algorithm. The final output of this work is then the distribution of building blocks within the metasurface that imprints into the impinging beam the previously calculated phase profile.
