New Areas of the Ultrasonic Application in Microelectronics Technology
Buršík, Martin ; Pietriková, Alena (referee) ; Králová,, Iva (referee) ; Szendiuch, Ivan (advisor)
Doctoral thesis deals with the deposition of special thixotropic materials for microelectronic technology. The aim of the work is the development of the new method optimizing the dosing process in order to achieve a print resolution of better than 100 microns. The work includes the development of a special dispensing head (UZD) using the influence of ultrasonic energy. These results demonstrate the possibility of a newly developed method that is able to print thixotropic materials with a resolution of 65 microns. Compared to other methods achieves these results with the commonly used materials for thick film technology with particle size up to 5 microns.

Diploma work
Němec, Jakub ; Magid, Václav (referee) ; Mikyta, Svätopluk (advisor)
The aim of my work is to reflect expression coincidence that reflects the theoretical basis of cellular automata and quantum mechanics. I think that art should point to examples of accurate knowledge and in this way spread among potential viewers. This is how I try to get closer to the subjective utopian society WERP-VEGA. I am not entirely convinced that fine arts can change the political situation or address fundamental civilization complications, but I believe that art is able to predict freely one of the possible scenarios of the future because one is only able to do what he can imagine.

Polygrafic production PROGRAF
Ptáčková, Eva ; Burianová, Lenka (referee) ; Kacálek, Petr (advisor)
The aim of this Diploma thesis is the elaboration of the project documentation of a construction part for realization of the new building of the production hall and administrative building in a city of Slavkov u Brna. According to the local zoning plan, both buildings are designed on a plot in the development part of the city. The selected plot is conveniently located due to good accessibility to the D1 motorway. The office building will consist of two above-ground floors. On the first floor there will be the management of the company and the head of the press, the economic and commercial department, hygienic facilities. On the second floor there wil be a graphic studio, a day room and a spacious terrace. The construction system of an office building will be a wall longitudinal. The ground plan of the object is rectangular. the roof is designed as a mono-pitched roof. The factory is a single-storey building. Inside the factory hall there will be a polygraphical technological equipment. The location of the machines is only indicative as well as their choice. The hall will have its own equipment equipped with air conditioning and heating. It is designed as a precast concrete frame. The system is designed longitudinal. The object is a rectangular ground plan with a saddle roof.

Photocatalytic Activity of Titanium Dioxide Printed Layers
Novotná, Michaela ; Jančovičová, Viera (referee) ; Veselý, Michal (advisor)
This diploma thesis was focused on the preparation of self-cleaning and photocatalyticaly active titanium dioxide thin films. Transparent and porous thin layers of titanium dioxide were prepared from sol-gel containing titanium tetraisopropoxide (TTIP) as precursor with addition polyethylene glycol (PEG). Transparent thin layers of titanium dioxide were also prepared from colloidal solution titanium dioxide. The immobilization of thin titanium dioxide layers was performed by a sol-gel process on the soda lime glasses. Diffusion of sodium cation from soda lime glasses into titanium dioxide layer were blocked. Sol was deposited by printig method – micropiezo deposition. Sol and thin titanium dioxide layers were characterised by the physical-chemical method. For prepared sol viscosity, density and surface tension were measured. Thickness and hydrophilicity of titanium dioxide layers also were studied. The photocatalytic activity of the printed titanium layers were tested via the photocatalytic degradation of the 2,6-dichlorindophenol. The influence of addition PEG into the sol and influence of sol loading was studied. It was found that the addition of PEG into the sol significantly increased the photocatalytic activity of titanium dioxide layers.

Business Cards Generator
Šerý, Radek ; Švub, Miroslav (referee) ; Chudý, Peter (advisor)
Business cards belong to common daily communication tool mainly due to the ease of the exchange of basic information. This bachelor thesis deals with the creation of a web application that will allow a preparation of a card corresponding to the proper typographical rules. The output of this application is a PDF file, which contains the user designed business cards and the crop marks, and is thus ready to print and cut into individual cards.

Preparation of Stuctured Thin Layers of Titanium Dioxide
Lukešová, Magdalena ; Jančovičová, Viera (referee) ; Veselý, Michal (advisor)
Cílem práce bylo seznámit se s dostupnými zdroji popisujícími zkoumanou tématiku tenkých vrstev oxidu titaničitého. Na připravených tenkých filmech byla studována fotokatalytická aktivita a indukované hydrofilní vlastnosti. Transparentní filmy oxidu titaničitého byly připraveny na sodnovápenatém skle metodou sol-gel. Na přípravu TiO2 solu byl použit tetraisopropoxid titaničitý (TTIP) jako prekurzor. Přidaný polyethylen glykol (PEG) sloužil jako strukturu-řídící složka, acetyl aceton zase ovlivňoval hydrolyzační a kondenzační reakce. Pro nanášení solu na skleněné destičky byla použita technika mikropiezo depozice. Na získaných filmech byla studována fotokatalytická aktivita prostřednictvím degradace 2,6-dichlorindofenolu (DCIP). Rychlost odbourávání DCIP byla vyjádřena pomocí formální rychlostní konstanty reakce prvního řádu. Měřením kontaktního úhlu byla zkoumána smáčecí schopnost vrstev. Filmy, které byly vystaveny ultrafialovému záření, se chovaly superhydrofilně.

Proposal of E-shop Designing for AREAL SYSTEMS s.r.o.
Parimucha, Petr ; Skoumal, Stanislav (referee) ; Skoumal, Stanislav (referee) ; Luhan, Jan (advisor)
This bachelor’s thesis deals with the proposal of a new e-shop for AREAL SYSTEMS s.r.o. The e-shop will sell individually manufactured wall stickers. The proposal is divided into two parts - technical and marketing. The technical part reviews the investment of buying a plotter and programming the e-shop. In the second part I will discuss the promotion possibilities on the internet and suggest their most appropriate combination. Finally I review the financial angle.
