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.

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.

Surface casting defects
Rašek, Ondřej ; Pernica, Vítězslav (referee) ; Tomek, Ladislav (advisor)
Surface defects in casting include after decades of research on current problems of metal cast. They mean significant losses for foundries. Thesis includes a review of kinds of defects, their origins and their examinations, the effects on the mechanical properties and their machinability.

Special surface finish architectural concrete
Gajdoš, Jan ; Ťažký, Tomáš (referee) ; Hela, Rudolf (advisor)
The aim of this work is to describe modern methods of finishing concrete with architectural division of the surfaces created in fresh and hardened state. In this work describes the various influences and their effects on the resulting surface such as concrete composition, method of storage or production and compaction of concrete. In the practical part of the thesis focuses on the technology of graphic concrete and its application to vertical monolithic wall.

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.

Surface integrity after waterjet cutting process
Pešata, Jan ; Slaný, Martin (referee) ; Dvořák, Jaromír (advisor)
is thesis on subject "Surface integrity after waterjet cutting process" describes problem of the progressive advanced technology, unconventional hydroabrasive jet cutting, examines the integrity of the surface after cutting AWJ and discusses selected factors on the outcome of the cutting process. Also, there are mentioned accompany effects of cutting process and the various applications of AWJ. A special attention is devoted to the surface integrity evaluation in terms of its quality. Next was attention to factors entering into the process of division and affecting the surface topography.

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.

Surface Modification of Ferrous Materials
Jakubčíková, Lucie ; Tulka, Jaromír (referee) ; Molliková, Eva (advisor)
The bachelor´s thesis is about surface treatments. There are mentioned iron-based materials and their marking. The process of corrosion and wear of materials is described. Then is analyzed the main topic of surface pretreatments, metal, inorganic non-metallic and organic coatings. The basic properties of the coatings and their testing is described. At the end are mentioned the negative effects of the surface treatments.
