Centre for Prevention, Masaryk Oncology Institute in Brno
Buzová, Magdaléna ; Kraus, David (referee) ; Galeová, Nicol (advisor)
The objective of the diploma thesis is the new building of Cancer Prevention Centre, first of its kind in the Czech Republic. The site is located on steep terrain of the south hillside of Žlutý kopec in Brno, which is a part of Masaryk Oncological Hospital complex. The aim of the Cancer Prevention Centre is to attract the citizens’ attention and invite them to undergo a preventive medical check-up with the potential to save hundreds of lives every year. The project takes this fact in consideration and strives to find ways leading not only towards establishing new relationship between the building and the public, but also towards connecting the city centre and nearby by residential area with the hospital complex. The three volumes of the buildings create a dynamic composition and therefore complete the characteristic development of Masaryk Oncological Centre. The main concept however revolves around the motive of instability, balance and journey which are all linked to tumour diseases.

Teaching-space paradigm
Vašička, Pavel ; Müller, Rudolf (referee) ; Rozwalka, Szymon (advisor)
The aim of the bachelor's thesis is to create a new Faculty of Architecture in close proximity to the Faculty of Fine Arts on the BUT campus. The aim was to achieve a dignified environment for teaching future architects. In the complex there is a building designed for the Faculty of Architecture. However, it does not have sufficient capacity to cover teaching needs. Therefore, both the existing building and the extension and their interconnection were solved within the project. The main goal of the project was to create an environment that reflects today. The architect in particular should have a more general overview. The premises are as open and shared as possible, so that the students themselves enrich each other as much as possible. Emphasis is placed on the open layout of the interior, into which the exterior blends in selected places, the floors are enriched with atriums and elevated floors, which allow greater social contact.

The subject of the experiment is to determine the effect of the temperature in the tempering furnace and the effect of the used slats on the dimensions of the polycarbonate molding. 3D measurements are used to evaluace dimensionality. The influence of the slats is examined with free types of slats.
Corrosion resistance of PA and PC components
Mikel, David ; Pospíšil, Ladislav (referee) ; Jančář, Josef (advisor)
The influence of two lubricating and cleaning agents and diesel fuel on environmental stress cracking of polyamide reinforced by glass fibers and polycarbonate was studied in this master thesis. Testing of environmental stress cracking was performed by the method of critical bending deformation. Bergen elliptical strain jig was used for testing. The test liquids caused varying levels of environmental stress cracking of amorphous polycarbonate, but they did not cause environmental stress cracking of glass fiber reinforced polyamide. The test method used allows testing the resistance of both materials against environmental stress cracking of any liquid. The results can be used to design products that are expected to be exposed to corrosive liquids. Quantification of the influence of stress free corrosion on the static and impact properties of polycarbonate and glass fiber reinforced polyamide was performed by accelerated test. Specimens were exposed to test liquid and an elevated temperature of 70 °C. The mechanical properties of the tested materials were significantly affected by elevated temperature exposure. The yield strength of the polycarbonate has increased and the toughness has decreased due to physical aging. The tensile strength of glass fiber reinforced polyamide has increased due to a decrease of the moisture content of the material.
