The Case
Svobodová, Hana ; Šrek Bromová, Veronika (referee) ; Gabriel, Michal (advisor)
I assume huddled topic that I put into my past work as well as in final work. Casting my body, which is covered with feathers and create a cocoon of him, husk without the interior. Sculpture has two sides, the principle of duality, femininity and counterpart. Outer packaging evokes pleasant birdlike body surface and in the inner part aggressively squeeze ends of the wicks feathers.

Negative
Videmanová, Marie ; Žáková, Radka (referee) ; Gabriel, Michal (advisor)
The inspiration for this sculpture has gradually arisen from the experience of the previous work. I used to be in the sleeping people, in the statues of life-sized human bodies. These sculptures deformed, transformed and manipulated by various manipulations, thus getting them into unrealistic positions. These changes made it possible to see the statues, to look at their dreams. The sculptures then acted as holy scenes from the churches. The normal position of a sleeping man turned into a kind of gesture when turning. With this creation of a series of sleeping people, I cast negative shapes of castings while casting live models. Unfortunately, these negatives are one-off and are destroyed and not treated in the next process. At this time, I began to understand these negatives not only as an intermediate but also as a sculpture output that had the same function and value for me as a classic statue. Like a print, like a dream, depicting reality. This dream allows the audience to enter the figures, into their dreams. In my bachelor thesis I therefore continue to deal with human forms but in their opposite form, and I can say that I am creating a game of forms and playing with them. I did not stay with the classic forms of the bas-relief, so with the classic negative relief, but I embedded my negatives into cubes, which act as a game of cubes, which can be arranged, rotated, tossed. In my bachelor thesis I create a small group of three dice that allow this game. Cubes have only one possibility where two human characters, two human fingerprints of men and women follow. All the other possibilities of arranging the dice with the prints of these two figures are no longer logically unrelated - they follow unreasonably. Just as it is in dreams. In most cases, we have something logical in our dreams, such as characters and / or nature, but then it becomes always unrealistic in the dreams that we start flying. And these dice are like dreams - sometimes real, but mostly chaotic. That's why I gave my work a subtitle: "Negative Dreams" The word "negative" comes from the form of the statue I chose and the "dreams" of my idea, the inspiration I want to see for the viewer. Analyzing dreams, how they work, and how it enters our subconscious mind, I can not do it, I just create my own game inspired by dreaming into dreams. Dreams that seem to these two people in particular and which are diverse. I just built this work on my vision of looking into these dreams and how these dreams work. When the dream seems to me, it has a real background and then goes into something abnormal, unrealistic. Thanks to manipulation with dice I have the ability to change the real in unreal. I play dice with these two prints of people, the prints of their dreams. In my work, it represents the real basis of the dream arrangement of the cubes, in which the imprints of the two characters are anatomically linked. And then the dream comes and the dice regroup. The author or viewer has the ability to swap, change, and dice. Reality will change into a dream. The characters in a dream can be unnaturally linked or not at all. From one particular happening, a number of other, chaotic stories are developing. For the presentation of my bachelor thesis I chose the very "real" position where the characters follow on, they work. The cubes are built in a column to allow them to walk around and look at both figures. I photographed some other possibilities in various variants, lying, turned, shu

Segregation during solidification in austenitic-ferritic stainless steels
Kejha, Richard ; Čech, Jan (referee) ; Pernica, Vítězslav (advisor)
The master thesis deals with processes of segregation in austenitic-ferritic stainless steels. The introductory part consists of characteristics features of austenitic-ferritic steels and theoretical analysis of segregation processes. The second part shows practical measurements of segregation in experimental casting. Macrosegregation was measured on a spectrometric analyzer and simultaneously solved in the simulation program MAGMA. The aim of this thesis is to verify the effect of solidification time and dwell time between liquidus and solidus temperature on the chemical heterogeneity of duplex stainless steel casting of about 500 [mm]. Chemical heterogeneity was solved for selected alloying and accompanying elements such as C, Mo, Ni, Mn, Cr. The microsegregation was not addressed. Comparison of the mechanical properties of cast and heat treated duplex steel was done by tensile testing of samples cut from the center of the casting.
