ZOO BUILDINGS – HERALDIC ZOO
Valchová, Jana ; Pospíšil, Zdeněk (referee) ; Boháč, Ivo (advisor)
The main idea of project is to design heraldic zoo in the area of old castle park Horní Hrad, which is located few kilometers next to the Karlovy Vary. Heraldry is science of knowledge of family symbols. Concretely it will be zoo, which will be focused on animals, which can be found on the old czech signs. The idea comes from surrounding relations of dramatic terrain and it's affected by context of the historic monument. Castle is the huge dominant of the all views to the surrounding countryside.
Science and Technology in Media
Gellnerová, Zuzana ; Haupt, Jaromír (referee) ; Smutný, Milan (advisor)
Tato práce se zabývá vlivem médií, především nových médií, na oblast vědy a techniky. Definuje základní mediální pojmy a upozorňuje na to, že média mohou být výborným prostředkem k propagaci vědy a techniky, ale mají také obrovskou moc a mohou zkreslovat realitu a manipulovat s lidmi. V práci je také rozebráno několik konkrétních příkladů. V závěru práce je nastíněn možný pohled do budoucna propojení vědy, techniky a médií.
Methods of deep learning in image processing tasks
Polášková, Lenka ; Marcoň, Petr (referee) ; Mikulka, Jan (advisor)
The clue of learning to recognize objects using neural network lies in imitation of animal neural network's behavior. In spite the details of how brain works is not known yet, the teams consisting of scientists from various medical or technical professions are trying to search for them. Thanks to giants like Geoffrey Hinton science made a big progress in this domain. The convolutional networks which are based on animal model of optical system can be advantageously used for image segmentation and therefore they ware chosen for segmentation of tumor and edema from images of magnetic resonance. The models of artificial neural networks used in this work had achieved the 41\% of success in edema segmentation and 79\% in segmentation of tumor from brain issue.
Metal Matrix Composites Prepared by Powder Metallurgy Route
Moravčík, Igor ; Lapin, Juraj (referee) ; Skotnicová, Kateřina (referee) ; Dlouhý, Ivo (advisor)
Ve všeobecnosti, poznatky o design slitin, jejich výrobě a výběru legujúcich prvků sú omezené na slitiny s jedním základním prvkem. Tento fakt ale výrazně limituje možnosti a volnost výběru prvků pro dosáhnuti speciálních vlastností a mikrostruktur. V poslední dekádě se ukázalo, že materiálová věda a inženýrství nejsou ještě zdaleka prozkoumané v důsledku objevu nové třídy materiálů nazvané vysoko entropické slitiny (HEA high entropy alloys). Jejich objev upoutal pozornost vědecké komunity. Základní koncept pro jejich design je, že namísto jednoho, nebo dvou základních prvků obsahují minimálně 5 prvků v podobných atomových koncentracích. V posledních letech se objevila skupina materiálů odvozená od HEA, nazvaná slitiny so střednou entropii (MEA medium entropy alloys). Na rozdíl od HEA ale obsahují 3, nebo 4 prvky. Táto práce je věnovaná studiu přípravy a charakterizaci HEA, MEA a jejich kompozitů s pomocí metod práškové metalurgie. V této práci byli dohromady zkoumány tři kompozice: AlCoCrFeNiTi0.5, Co1.5Ni1.5CrFeTi0.5 a CoCrNi, kompozity s kovovou matricí (MMC metal matrix composites) vyztužené částicemi B4C s CoCrNi jako matricí. Hloubková mikrostrukturní a mechanická analýza těchto materiálů byla provedena pomoví metod rastrovací a transmisní elektronové mikroskopie spojené s tahovými a ohybovými zkouškami. V průběhu celé studie se objevovaly problémy s kontaminací kyslíkem, co se projevilo vznikem značného množství oxidů v připravených materiálech. U Slitiny AlCoCrFeNiTi0.5 byla naměřena tvrdost přesahující 800 HV. Její houževnatost ale byla velice omezena. V její mikrostruktuře byly identifikovány částice in-situ TiC v důsledku přítomnosti organického, anti-aglomeračního činidla (metanolu) v mlecí misce. Tato reakce může být použita v budoucnu k přípravě MMC se záměrnou disperzí TiC. Na druhé straně, slitina CoCrNi ukázala vysoké hodnoty tažnosti (26%) a meze pevnosti přes 1000 MPa. Mikrostruktura obsahovala majoritní FCC fázi s BCC precipitáty. Tahle slitina byla z důvodu vysoké tažnosti zvolena pro přípravu kompozitu s výztuží B4C. V průběhu slinování ale došlo k reakci mezi přítomným Cr a B4C, které výsledkem byl Cr5B3 borid. Tento kompozit mel pevnost v tahu 1400 MP a extrémne jemnozrnnou strukturu. Celková tažnost ale klesla na 1.9 %. Slitina AlCoCrFeNiTi0.5, která mela strukturu složenou jen z FCC tuhého roztoku dosáhla nejlepší kombinaci mechanických vlastností s pevností přesahující 1300 MPa a dostatečnou tažností 4%. Prášková metalurgie se ukázala jako vhodná metoda pro přípravu HEA a MEA slitin a jejich kompozitů, s dobrou kombinací pevnosti a tažnosti. Tato metoda dovoluje měnit mikrostrukturní parametry připravených materiálů jednoduchou úpravou parametrů procesu.

Analysis of the impact of the baffle placement in the supersonic flow in the differentially pumped chamber
Vlasáková, Martina ; Bílek, Michal (referee) ; Maxa, Jiří (advisor)
This thesis deals with the area of the differential pumping chamber of an environmental scanning electron microscope, engaging the pressure limiting apertures and the influence of the enclosure inside the chamber. In the theoretical part, it is first called Microscopy as science, information about microscopes (division of microscopes) and electrons. Afterwards, the theory deals directly with environmental scanning electron microscopy and its problems and vacuum system, mathematical models and computational areas, basic information about the comparative study from, which the thesis is based. In the experimental part there are presented the objectives of the work and the chapter dealing with the processing of results, which are compared with the initial study using the program Ansys Fluent.
The object of metropolitan significance on the street Benesova Brno
Střeštíková, Vendula ; Pospíšil, Zdeněk (referee) ; Boháč, Ivo (advisor)
This paper is focused on proposal object or group objects of metropolitan purpose on the specified ground. Character of this object should fit the other current objects along Ringstrasse. My task is react on the system of parks and urban vegetation which is part of this ringstrasse. I also have to design new ground of urban vegetation which will react on the city needs. New object will be multipurpose science-educational center which reflect the quality of science and research in Brno that is valued like scientific metropolis and the most important center of science over all republic. The most important idea of this draft is give the whole city an object which will be a new dominant of this Ringstrasse. The main effort was create building a multi-purpose utilization like a core of all project. Final design is multi-purpose object of science-educational center which can reflect Brno as scientific metropolis and react of the fact that there are about 90 000 university’s students. The main concept is the beginning of life and it was created as a response to the analyze and research and is the entire design philosophy. This was reflected to the all phases of project and details.

Nanotechnology educational and research center (NanoArch)
Hamdanieh, Livine ; Boleslavská, Yvona (referee) ; Žalmanová, Petra (advisor)
„Science, the Never-Ending Quest.“ The diploma thesis deals with a proposal of science center aimed at promoting science and education in the field of nanotechnology. The aim of the project is to design a science center that will complement the existing building complex of CEITEC Nano BUT but also through its architectural expression represent the value of such institution and enable it to stand out among the existing buildings, allowing it to become the new center „brain“ of the complex. Nanotechnology represents a significant sphere of the scientific world that holds big potential for the future in various industries including architecture and building construction. The aim of the diploma thesis is thus not only to design new science center but also to raise awarness of nanotechnolgy. The design proposal is based on simple geometric shape - circle which is segmented into three parts. Logical shape of circle complements the already existing complex and becomes the new center point "brain" of the whole complex. The symbol of infinity that circle and Mobius strip represent is associated with the never ending scientific research as the science itself is at the end nothing but a "never ending quest".
