Study of sewerage in village Nasavrky
Sedláček, Ondřej ; Beránek, Josef (referee) ; Raclavský, Jaroslav (advisor)
The author of master's thesis submit study of alternative solution sewerage in Nasarvky. He made passportization and he design gravity, pressure and vacuum sewerage for the area of interest. He deals with the problems about storm sewerage and he design suitable solution. The study content issues technical and economic variants valorization. Object of study is recommendation the best alternative sewerage in Nasavrky.

Block of flats, Újezd u Brna
Sedláček, Ondřej ; Macků, Michal (referee) ; Müller, Jan (advisor)
This work deals with a new building – block of flats on land no. 1799/1, 1800/1 cadastral Újezd u Brna, region Brno - venkov. This building contains 15 individual flats. The object is geometrically divided on central part with gabled roof and 2 side parts with hip roof. Slopes of roofs 10°. Building is designed as three-storey object without a cellarage, whence all three storeys are residential . The building is accessible from local road and it is possible to park a car next to the object in new-build parking place. Residential rooms are positively rotated to south and ventilated naturally. All the residential rooms are exposed to direct day light. Sidewalk and hard surface are treated as concrete and scrubbed pavement. Construction peripheral bearing masonry, interior bearing masonry and cross buntons effected from ceramic breeze-block POROTHERM. Ceilings plates are made of reinforced concrete. Staircase are made of reinforced concrete as well.

Multilayer barrier coatings
Sedláček, Ondřej ; Mazánková, Věra (referee) ; Přikryl, Radek (advisor)
The theme of this work is the preparation and characterization of multilayer barrier coatings to polymer and metal substrates based on SiOx and organic molecules. It deals with the determination of their properties in terms of oxygen permeability and corrosion protection. The starting materials for the preparation of these layers are hexamethyldisiloxane, octafluorocyclobutane and 4,12-dichloro[2.2]paracyclophane. These layers have been prepared with regard to their use as barrier coatings for use in archeology, with the focus on corrosion protection of coated items and other specific requirements museums. For these samples was realized characteristic of both in terms of their physical properties – the ability to resist permeation of oxygen and in terms of their chemical composition. The fourier transformation infrared spectroscopy (FTIR), scanning elektron microscopy (SEM), oxygen transmission rate (OTR), contac angle measurement and corrosion testing were used for the above-mentioned characterisations.

SiOx based barrier coatings
Sedláček, Ondřej ; Dzik, Petr (referee) ; Přikryl, Radek (advisor)
The theme of this thesis is based on the preparation and characterization thin films prepared by methods like a Physical Vapor Deposition, Plasma Assisted Vapor Deposition and Plasma Enhanced Chemical Vapor Deposition. The elementary materials for the preparation of these layers are silicon monooxide powder, melamine and hexamethyldisiloxane. These layers have been prepared with regards to their usage like a barrier coatings with emphasis on poisonous organic substances resistance.. We made a characterization of these films. This characterization is consist of researching of their physical properties (the ability to resist permeation of certain organic compounds), and their chemical composition too. We used to some specific method for these characteristics, for example: FTIR, OTR, ellipsometry, SEM and measuring of the permeation of selected industrial pollutants resistance.

Natural drop structure on Morávka river after 4 years functioning
Sedláček, Ondřej ; Veselý,, Jaroslav (referee) ; Zachoval, Zbyněk (advisor)
The author of bachelor’s thesis deals construction local river widening. For a better understanding of the text he perform search retrieval basis of hydraulics and result research dealing with the local river widening. The next section he deals with facility to processing and evaluation data. In the practical part he describe nature drop structure on the Morávka river, where he compare original state with actual state after four years functioning and he recommend changes and repairs.
