Deduplication methods in databases
Vávra, Petr ; Kyjonka, Vladimír (advisor) ; Skopal, Tomáš (referee)
In the present work we study the record deduplication problem as an issue of data quality. We define duplicates as records having different syntax and the same semantics and which are representing the same real-world entity. The main goal of this work is to provide the overview of existing deduplication methods according to their requirements, results and usability. We focus on the comparison of two groups of record deduplication methods - with and without the domain knowledge. Therefore, the second part of this work is dedicated to the implementation of our method which does not utilize any domain knowledge and compare its results with the results of commercial tool deeply utilizing the domain knowledge.

WebDAV client with automatic synchronization
Vávra, Petr ; Dokulil, Jiří (referee) ; Trčka, Martin (advisor)
The aim of this work is to design "dual panel" file manager with WebDAV protocol support which extends well-known HTTP. The application is an alternative to FTP clients. That brings some benefits such as ability to work behind firewall or cooperation support. The application provides well arranged graphical user interface to manage either local or webdav files. Users can run basic file operations like copy, move, rename, delete within local and webdav directories or between them. Furthermore, the application offers sophisticated synchronizaction support. It allows users to run oneshot synchronization of two directories especially the local and webdav one. What is more, the automatic synchronization checks every changes in source directory and carry out the appropriate file operations in destination directory. The other features of the application are the ability to lock webdav files and directories, saving connections profiles and secure communication over HTTPS.

Air tightness of building structures and critical details
Vávra, Petr ; Tichomirov,, Vladimír (referee) ; Bečkovský, David (advisor)
In thesis is dealt with problematic of how the value of air permeability may be affected by properties for water vapour diffusion with regard to OSB material There were chosen two main brands of OSB at Czech trade market Two specimens of OSB with different thickness were chosen for each brand. As a first the specimens were tested for air tightness to work out a value of air permeability for each specimen. Afterwords, the testing was conducted for gaining properties of water vapour diffusion on each specimen. As a final assessment was analysed the impact of properties of water vapour diffusion on the air tightness for each specimen. The general meaning of gaining higher air tightness with higher water vapour resistance was proved . It was shown that with raising thickness is usually gotten higher value of water vapour diffusion resistance. However it could not mean getting high air tightness. The crucial parameter is the quality of the material for gaining higher resistance against water vapour diffusion as well as for higher airtightness.

Family house with a brewery T: O: P in Jevíčko
Němeček, Pavel ; Vávra, Petr (referee) ; Brzoň, Roman (advisor)
Bachelor´s thesis is focused on a project of a detached family house with a brewery T:O:P on a site 88/13 and 88/14 in a Jevíčko. Bachelor´s thesis is drawn in a project documentation for the realization of building. The house has two floors without cellarage, rectangular plan with flat roof, based on strip foundations made of a simple concrete. Vertical frameworks are devised from masonry type therm from Porotherm. Horizontal frameworks are from ceiling panels Spiroll. External wals are warmed by a contact system from polystyrene. Entry into the brewery premises and residential units, located on the second floor, is oriented to the southeast, entrance to the brasserie on the southwest. 1.NP is divided into two service. The service brewery with his technological background and administrative background brewer. The second service is brasserie brewery with his social service and visitors. Housing unit is separated from the brewery and brasserie ceiling constructions and has its own entrance from the open air.

Detached Family Residence
Mikuš, Martin ; Vávra, Petr (referee) ; Vajkay, František (advisor)
The subject of this work is the design of a detached family house in area Nove Domky near Jihlava in which natural construction materials were used. Instead of concrete or bricks, this building is designed with materials such as straw, rock, timber, clay, hemp or sheep's wool. Furthermore, the work deals with methods of plumbing, electrical installations and heating. The possible utilization of natural energy resources or ecological processing of waste were also taken into account. The conclusion contains the financial comparison with a building where traditional and industrially produced materials are used.
