Replacement of headlamp parts screw fixation by a plastic nail
Lysa, Bohuslav ; Píška, Miroslav (referee) ; Polzer, Aleš (advisor)
The master thesis covers several issues linked to a substitution of headlamp screw fixation by a plastic nail. The thesis includes an analysis of the headlamp technology, including description of the prescribed durability tests. On the basis of the analysis some new designs of plastic nails are proposed, consistent with characteristics of plastic materials. Selected outcomes of the analysis have been tested as prototypes and verified with Finite Elements Method in SimDesigner including 3D modeling capabilities provided by the Catia V5. The feasibility study regarding a casting form of the new design of plastic nails and technical economic valuation for contingent assembly mounting is included in the thesis.

Composite printing for 3D FDM printer
Műller, Jakub ; Sliwková, Petra (referee) ; Zemčík, Oskar (advisor)
This diploma thesis deals with the study of 3D printing based on the FDM method. This method focuses on the possibility of using two extruders it means that the composite parts can be printed. This diploma thesis describes the available variants of composite printing currently on the market. Based on the gained knowledge and the availability of 3D printers and software, individual variants of composite parts were printed. A tensile test was performed on these samples to determine the strength characteristics. Additionally, compatibility and adhesion of two selected materials were tested. Based on the testing is made an evaluation of the achieved results, effectiveness and feasibility.

Elimination of internal stress in the polycarbonate moldings
Selucký, Jaroslav ; Hrbáček, Jan (referee) ; Chladil, Josef (advisor)
This diploma theses raises the issue of internal tension in two-component outer lense, which are made by injection of polycarbonate. The theses gives a more detail view on treatment of the lenses in heating ovens. Heating ovens have been used for decreasing the internal tension in lenses. The subject of the experiment is to determine the influences of the adjustable parameters of the heating oven. The Experiment will be taken by DoE method. The influence of the adjustable parameters is researched and compared among the two types of outer lense with different type of design.

Polyethylenterepthalate Copper Plating for Conductive Structures Realisation
Chmela, Ondřej ; Zatloukal, Miroslav (referee) ; Starý, Jiří (advisor)
The content of this master’s thesis are methods of pretreatment and coating of the surface of PET to produce conductive copper structure and quality control. Thesis also includes theoretical analysis of these methods. Physical and chemical techniques of surface pretreatment methods are discussed in the theoretical part as well as methods making surface of substrate conductive, the subsequent galvanic copper plating and quality control of coating and testing of the adhesion between layers. The experimental part focuses on two methods of the polymer material surface pretreatments. The properties of these pretreatments were evaluated by using the atomic force microscopy and detection of surface energy by wetting and contact angle measurements. The surface is making conductive with cathode sputtering and electrochemical coating of copper. Adhesion of layers is tested mainly with scratch test and other methods. The results of these sub-operations are used for the realization of multi-layer conductive structures.

Advanced PC/ABS blends
Siudová, Alena ; Lepcio, Petr (referee) ; Ondreáš, František (advisor)
This diploma thesis studies mixtures of polycarbonate and acrylonitryl-butadiene-styrene. It deals with optimization of their production on laboratory scale and characterization of their properties. It compares the results with a sample prepared by a commercial partner in normal production. It tries to improve the properties of the prepared mixtures by means of nanofillers, compatibilizers and toughness modifiers. It compares and discusses the results of individual recipes, namely the relationships between microstructure, rheological properties and mechanical properties.

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.

Influences on the Creation and Size of Interpenetration Layers During Lacquering of Polycarbonate Moldings
Svobodová, Hana ; Dočekalová, Julie (referee) ; Sedlák, Josef (advisor)
Diploma thesis is focused on influences on the creation and size of interpenetration layers during lacquering of polycarbonate mouldings. In the diploma thesis there is a complete description of the production of the external lens for the automobile headlight. The experimental part consists of five experiments. The subject of the experiment is to find the most optimal process settings or other solutions that would lead to positive results of chemical tests. During the tests the individual phases of the production process are examined. After each experiment follows execution and evaluation of chemical tests in the reliability laboratory.

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.
