Parsing Based on Automata with Deep Pushdowns
Pločicová, Dominika ; Dvořák, Tomáš (referee) ; Meduna, Alexandr (advisor)
Language is a basic means of communication. Formal languages provide the basis for human-computer communication. The aim of this work is to contribute to this area and analyze the possibility of processing the context-sensitive elements of formal languages. The work includes the theoretical description of state grammar and deep pushdown automaton, which is a model of a parser for languages including context-sensitive elements. It describes an algorithm that can convert the state grammar to the said deep pushdown automaton. The work further describes parsing, its methods and the use of the created automaton in performing the syntax analysis. For a better understanding, the work also includes examples of the creation and operation of the automaton. Finally, the work describes the implementation of a program that performs theoretically described activities. The functionality of the program was verified on examples, whose inputs and outputs are also part of the text of the work.

Automation of measurement of disturbance influence on DSL modem transmission
Dvořák, Tomáš ; Šedý, Jakub (referee) ; Šilhavý, Pavel (advisor)
Goal of this work was to develop software to control noise injector DLS-5410DC and noise generator DLS-5800 and be able to perform automatized measurement of tranmission parameters of DSL line.The first part describes different noises on DSL line. In second part is described the software, how it was designed and developed. Software allows user to remote control devices, edit and apply noise profiles and perform automatized measurement of transfer characteristics. Software was programmed in C\# programming language on .NET Framework 4.0 platform. For programming was used Microsoft Visual Studio 2012.

BRIDGE ON D1 (LIETAVSKÁ LÚČKA - VIŠŇOVÉ) OVER VALLEY AT km 4.313
Hudyma, Nazar ; Dvořák, Tomáš (referee) ; Zich, Miloš (advisor)
The subject of this Master's thesis is the design of a road bridge on the D1 in the section Lietavská Lúčka - Višňové in the Žilina Region, Žilina District, Slovak Republic. The bridge is used to cross the valley in KM 4,313 and the road in KM 4,410. Three variants of bridging were proposed, but further in the work an assessment is made on one of the variants. The total length of the superstructure is 354.00 m, the theoretical total span of the structure is 352.00 m. The bridge has 4 spans and is constructed by free cantilever method .The locations of the supports were limited by unsuitable geological conditions at the construction site (active shear area in Quaternary sediments), especially in span No. 3 (span lenght 104.00 m) and span No. 4 (span lenght 75.00 m). The monolithic part of the bridge structure will be concreted by free cantilever method with the largest length of the cantilever 52.00 m. The outermost parts of fields No. 1 and No. 4 will be cast-in-place using fixed scaffolding.

Revitalization Program of Floral Garden in Kromeriz
Dvořáková, Vendula ; Dvořák, Tomáš (referee) ; Mikulášek, David (advisor)
Floral Gardens Kromeriz – a landmark of transnational importance. It is an example which has influenced architectural development in Europe. This Libosad, which has evolved since the 17th century, was used for art loving guests’ delectation. At the present time this world full of antique gods’ sculptures, figures from history or myths; this world formed by espalier walls and blooming flower beds being it all underlined with the work of plasterers, sculptors and fresco painters; this Libosad world is not able to offer to a present person what she/he expects. Since the reason why people visit these gardens has partly changed. The majority of people come to see the landmark, which in 1998 got registered in the UNESCO World Cultural Heritage list, in the first place and they come to learn something about it. Once on this tourist occasion, they also have a rest and spend pleasant times in the gardens. As a result of that there comes a new space for gaining information and relaxation in one into being.

Dilatancy of soils as a factor influencing the bearing capacity and load - displacement response of deep foundations
Dvořák, Tomáš ; Koudela, Pavel (referee) ; Chalmovský, Juraj (advisor)
In theory of soil mechanic the dilatancy has a significant influence, which may fundamentally affect bearing capacity and behavior of geotechnical constructions. In the past it was difficult to include influence of dilatancy directly in to calculation, but now with development of numerical analysis and growth of computer performance it is much easier. In this work there are introduced fundamental dilatancy models and phenomen called constraint dilatancy, which causes stress changes in soil or at soil – construction interface. This stress changes may lead to higher bearing capacity. In this work, the effect of constraint dilatancy is focused on bored pile’s shaft. Next target of this work is including dilatancy to calculation. By empirical methods, by direct application with theory of cylindrical cavity expansion and last by numerical calculation with finite element method in software Plaxis with using the Hardening Soil model.
