Advanced techniques of micromachining
Šalomoun, Vojtěch ; Prášek, Jan (referee) ; Pekárek, Jan (advisor)
Fabrication of micro-electro-mechanical systems (MEMS) requires advanced level of miniaturization, which is not achievable by technology used in microeletronics. Socalled micromachining covers many unique techniques of material processing to get microstructures with possible dimensions below 1 m. This bachelor’s thesis gives a general introduce to micromachining of MEMS. Its focus is on bulk and surface micromachining by wet and dry etching. The practical part contains design of microstructures, their manufacturing process and creation of computer models in CoventorWare suite.

Processing of data from 3D scanner
Ječmínek, Tomáš ; Janda, Marcel (referee) ; Kuchyňková, Hana (advisor)
This work deals with the particular case of 3D scanning applications ZScanner 800. In bachelor work there was measured an fan geometry of induction engine. This geometry was subsequently adjusted using Geomagics. In parallel of these operations there were created 3D models of fan in SolidWorks program. The scanned surfaces and 3D fan model were used for dimensional analysis program in Geomagics.

Attraction
Kojetská, Monika ; Trnková, Barbora (referee) ; Kohoutková, Karolína (advisor)
In my thesis the focus is on the attraction with which I work in multiple planes. I focus on the essence of the material and its predictive value. I place emphasis on the significance of the use of specific material and use the category of its surface, superficies, fashion, luxury, kitsch, goodliness, atracction,object and desire. I work with visual, physical and sensual attraction.

Lilith
Šerý, Vítězslav ; Pinkava, Ivan (referee) ; Gabriel, Michal (advisor)
Statue The Lilith is figural sculpture that combines elements of hyperrealism with purely abstract element. Female figure sitting on a throne is wrapped and draped in unrelated elements and their relationships. That make her imaginary clothes. The statue is the result of interest in the topic of mystery and its sculptural representation. The statue is a combination of materials, mostly it consists of fiberglass and polyester.

Design of education board
Hadáček, Milan ; Buganská, Tamara (referee) ; Karásek, David (advisor)
The aim of my diploma thesis is to blueprint a design of multi-functional educational console. The dissertation contains several variant studies, color drawings and concrete shape execution. It entails a certain development in the area of positioning and multi-functional appliances. The thesis itself deals with the concrete shape execution of multi-touch educational console as well as seat in the form of gym ball. Short video cut from the area of interactive media forms a part of my work too.

ML PCB with Microvia - Production Line Design
Libich, Jiří ; Blansko, Jiří Zouhar, ČEMEBO (referee) ; Starý, Jiří (advisor)
This Bachelor thesis deals with the production of Printed Circuit Boards(PCBs), especially of the High Density Interconnection(HDI) type with microconnections. The aim of my thesis is to design and implement an technology equipments for the production of multilayer PCBs, more precisely four-layer PCBs, with the use of modern technology. The design was carried out for the company dealing with the production of PCBs. The Bachelor thesis was done in cooperation with ČEMEBO BLASNKO s.r.o.

Chemical modifications of polypropylene surfaces
Pospíšek, Marek ; Petrůj, Jaroslav (referee) ; Kučera, František (advisor)
Diploma thesis is focused on modification and characterization of polypropylene (PP) products surfaces by the chemical way. In theoretical part of thesis are summarized the current knowledge of this topic including characterization methods. Polypropylene surfaces were modified by acrylic monomers (acrylic acid, acrylic acid with 20 mol% content of sodium acrylate and acryl amide). Modified surfaces were characterized by infrared spectroscopy with ATR technique. The comparative parameter was carbonyl index determined from absorption peaks of functional methyl groups (2950 cm-1 ) and functional carbonyl groups (1700-1750 cm-1) of FTIR-ATR spectra. Determination of effect of initiator concentration on the modification process was done for acetophenone and benzophenone. There were determined the time dependence of carbonyl index for time from 0 to 600 s of mentioned monomers. In the same condition were modified test specimens designed for preparation of adhesive joints. Joints were bonded by cyanoacrylate adhesive that provide reaction with surface of polyacrylic acid. There were founded conditions of modification that provided strength of adhesive joints higher than strength of original PP. There were identified changes of surface roughness by using of confocal microscopy.
