Socio-cultural centre with townhall for the district Brno-Kohoutovice
Olivíková, Barbora ; Joura, Ivo (referee) ; Mikulášek, David (advisor)
The main goal of the proposal was to solve the problem of combining socio-cultural centre with town hall. To use flexibility and mix-use and connect all functions so they work together. The main idea about function of the building was how the people feels when they go to such a building as town hall. The goal was to propose the space which is transparent and remove the barriers between bureaucrats and public, so you can already see from outside what is happening inside. The concept was to design long building with the foyer along the side oriented towards the square. All is based on transparency which supports democracy and trust, removes weird feelings about solid walls and closed doors. The fasade is made from long thin wooden pieces with glass between, the appearence of the building is jumped and sloped and pointed shape which relates with the functions and break the stereotype of the estate urban structure.

Optimization of optical and transport properties of PVA based hydrogels
Zahrádka, Jan ; Kalina, Michal (referee) ; Sedláček, Petr (advisor)
The main goal of this bachelor thesis is to design and optimize a suitable method for preparation of transparent physically crosslinked hydrogels with manipulable transport properties. Polyvinyl alcohol (PVA) crosslinked by cyclic freezing and thawing was chosen as the model gel-forming material. From the originally proposed three mechanisms of influencing optical properties of thus prepared PVA gels, the influence of freezing rate was selected on the basis of pilot screening experiments for a deeper follow-up analysis. The mechanical properties of prepared hydrogels were analyzed by rheology using strain sweep test. The internal structure was visualized by scanning electron microscopy (SEM). The optimized technique for preparation of transparent PVA gels was subsequently used for preparation of gels with an interpenetrated polyelectrolyte component (poly (styrene sulfonate)). It was then experimentally verified by diffusion pair method with methylene blue as diffusion probe that the hybrid hydrogel network has modified transport properties.

Processing of compact polycrystalline YAG ceramics
Kaplan, Lukáš ; Pouchlý, Václav (referee) ; Kachlík, Martin (advisor)
In the literary part of this master thesis a research on various methods of preparation of dense polycrystalline YAG ceramics and the effects of sintering on the densification and other desired properties of such prepared YAG ceramics was carried out, the transparency after addition of dopant elements was also discussed. In the experimental part of the thesis, samples of dense polycrystalline YAG ceramics were prepared by SSR method and the effect of sintering on the densification and porosity of the YAG ceramic samples was studied. Relative density, porosity, phase purity and transparency were measured on the sintered samples. These measurements were compared with the results of the works reported in the literature section.

Archive+
Domiňáková, Michaela ; Ponešová, Barbora (referee) ; Kristek, Jan (advisor)
The design theme is not just the archive as a repository of past, but primarily center of architecture as a platform for sharing ideas and shifting boarders in architecture. This makes an institution with overlapping contradictory programs at different levels. It is both closed and open. These two counterparts are solved in spatial and material „spiral“. On the one hand, there is the notion of absolute closeness that of archive, on the other there is also the idea of the maximum openness of public space. Closeness and openness are transcribed in mass, materiality as well as programmatic solutions of space. The aim is to modulate the degree of social interaction in each of the spaces according to its function.

Sprayable elastic biopolymer hydrogels for wound healing
Waclawiková, Petra ; Nedomová, Eva (referee) ; Vojtová, Lucy (advisor)
Cíle prezentované bakalářské práce jsou zamšřeny na přípravu a charakteristiku sprejovatelných hydrogelů z vhodných netoxických látek, za účelem vyvinutí gelů aplikovatelných pro řízené hojení ran. Teoretická část se zabývá obecnými vlastnostmi hydrogelů, způsoby jejich síťování, a uvádí vybrané přírodní a syntetické materiály používané pro přípravu hydrogelů. Obsahuje také krátký přehled již připravených sprejovatelných hydrogelů, které ale zatím nejsou komerčně využívány. Experimentální část popisuje výběr a použití lehce dostupných netoxických materiálů a měření chemicko-fyzikálních vlastností z nich připravených gelů. Jako strukturní polymery byly zvoleny gum Karaya, poly(vinyl alcohol) a alginát sodný společně s různými fyzikálními síťovadly a aditivy. Polymery včetně aditiv byly podrobeny zkouškám rozpustnosti, a v určitých poměrech byly smíchány a následně síťovány za tvorby přednostně transparentních hydrogelů. Poté byly vyhodnoceny jejich optické a reologické vlastnosti. Z měření optických vlastností vyplývá, že gum Karaya ovlivňuje růst jak žlutosti, tak i transparentnosti připravených hydrogelů. Reologické měření prokázalo že vyšší obsah polysacharidu gum Karaya snižuje mechanickou odolnost připravených hydrogelů. Tuhost hydrogelů byla ovlivněna jak nízkou tak i vysokou koncentrací síťovadla, kde optimální množství vykázalo nejlepší výsledky. Správný poměr a dávkování použitých látek jsou tedy hlavními parametry pro získání nejvhodnějších vlastností hydrogelů pro sprejovatelné obvazy na hojení ran.

Twenty Eighty-Four
Truncová, Eva ; Sotelo, MArch Verónica Gallego (referee) ; Kristek, Jan (advisor)
The project follows up on the undergraduate work on the issue of control and surveillance in public space. Tendencies of absolute transparency, well-arranged and controllable public premises, supposedly implying security, are present in most of the newly emerging complexes of buildings and urban planning strategies. Whether it is done consciously or as a result of current “trends” and requirements, which only a few question, the space is built to meet these demands for easy controllability. The second method of control, which has also emerged during the era of modernism, is the control of the indoor climate through "mechanical environmental management" or through the use of fossil fuel energy for heating, cooling and ventilation. Current requirements for the comfort of the indoor environment presuppose a constantly, fully and homogeneously tempered environment, regardless of the outdoor climate or the time of year. Both control regimes permeate all measures of the urban environment and have a direct impact on its organization, form and, above all, on the regimes of its usage. Developers and their commissioned architects repeat well-proven business models and forms, without any major focus on the context of the place, and incorporate this "logic of control" into their buildings and surroundings. Housing complexes are planned and built up as one unit with a rigid structure and only a minimal possibility of their later alteration. The domain of control through transparency penetrates from the public space to the entrance door of the apartment unit. Indoor, social control changes to total control of the interior climate of the apartment, where the boundaries between seasons and day and night are blurred. The proposal is investigating alternative ways of urban planning and architecture. The project deals with the relationship between building, its surroundings and applicable regulations, standards and energy efficiency, along with the idea of adaptive living.

Realistic Visualisation of Alcoholic Beverages
Bartl, Vojtěch ; Kučiš, Michal (referee) ; Polok, Lukáš (advisor)
The object of thesis was to make a simple program for visualisation of alcoholic beverages. There was used a global illumination method raytracing, which serve the purpose to visualize 3D scene in photorealistic quality. The rays sent to the scene reflects and refracts on the interfaces and getting information about color of materials. Finally the ray determine the color of pixel. It's a very complicated process where it is necessary to solve passing rays through different interfaces.

Socio-cultural centre with townhall for the district Brno-Kohoutovice
Valošková, Tereza ; Pechman, Tomáš (referee) ; Sochor, Jan (advisor)
From a theoretical perspective, concept of City Hall building is built on three values: openness, transparency and community support. I understand these values at two perspektive: literally, as access to buildings not only in the opening hours of the town hall, and figuratively, as openness to other than bureaucratic functions. Town Hall should also promote cohesion and dynamism of the local community. Not just a casual setting where people spend just a neccesary time, but a space where people will want to delay a meeting. The value of transparency in my political and social environment is essential. Town Hall can, and should, give citizens view into the working space officials, as well they should not be cut off from events in the city. Flow of information to and perceptions can be beneficial for both sides.

Accountability of international NGOs
Staša, Michal ; Skovajsa, Marek (advisor) ; Muhič Dizdarevič, Selma (referee)
Diploma thesis concerns two current issues filling scholarly magazines in recent years. The first one is a discourse about the global civil society, its existence, definition and scope. Thesis maps the basic approaches and creates three groups of authors: globalists, skeptics and empiricists. The second issue is about the need of better accountability which arises after few scandals of global institutions in the early years of new century. The scandals didn't avoid the international non-governmental organizations. The diploma thesis summarizes few types of typologies of accountability and introduces the basic areas divided into the two groups: moral and political accountability and procedural and internal accountability. The research part of thesis comprises the accountability assessment of three branches of international non-governmental organizations: Amnesty International, Greenpeace and Hnutí DUHA - The Friends of the Earth. The goal was to find the appropriate methodology for assessing the national branches and verify it. The main result is the modification of an existing methodology of One World Trust organization and the finding that the organizations have the low rate of accountability.
