Syntactic Analyzer for Czech Language
Beneš, Vojtěch ; Otrusina, Lubomír (referee) ; Kouřil, Jan (advisor)
Master’s thesis describes theoretical basics, solution design, and implementation of constituency (phrasal) parser for Czech language, which is based on a part of speech association into phrases. Created program works with manually built and annotated Czech sample corpus to generate probabilistic context free grammar within runtime machine learning. Parser implementation, based on extended CKY algorithm, then for the input Czech sentence decides if the sentence can be generated by the created grammar and for the positive cases constructs the most probable derivation tree. This result is then compared with the expected parse to evaluate constituency parser success rate.

Gravity and magnetic survey of the east tectonic boundary of Cheb sedimentary basin
Buřičová, Pavla ; Blecha, Vratislav (advisor) ; Beneš, Vojtěch (referee)
Region of West Bohemia and the neighbouring German area Vogtland is characterized by its recent seismic activity. For better understanding of the distribution and origin of earthquake swarms it is necessary to know in detail the shallow as well as deeper geological structure of this area. This thesis deals with the geological and tectonic situation between villages Kopanina and Nový Kostel. In this area Mariánské Lázně Fault, which represents - from our point of view - the eastern marginal fault of the Cheb basin, is crossed with the fault zone Počátky - Plesná. The greatest amount of earthquakes hypocenters on the territory of Czech Republic have been registered in this region. The aim of this thesis is not only to find the eastern marginal fault of the Cheb basin, but also to define its course in the terrain and to determine its slope. Geophysical methods gravimetry, magnetometry and conductometry have been applied to identify these fault parameters. Geophysical methods were measured on three paralel profiles in August 2010 and in June 2011. The data from these profiles were consequently processed and geologically interpreted. During interpretation it was shown that contribution of magnetometry to recognition of different rock types and to identification of tectonic features was poor. On the...

Gravity survey and modeling of geological structures
Beránek, Roman ; Blecha, Vratislav (advisor) ; Beneš, Vojtěch (referee)
This thesis deals with the application of gravity survey to detect and delineate geological structures. The thesis further deals with various processing and interpretation methods, which include the creation of computer-generated models. To meet these goals, the gravity measurement was carried at the locality with the expected presence of abandoned historical mineshaft of known orientation. The goal is therefore to clarify and scrutinize information gained from various historical sources. Different models of survey area were made during the interpretation phase of the survey including 2D and 3D models according to the unknown recent state of the mineshaft. The result of this study is a comparison of several different approaches used in gravity surveys such as methods of elevation measurements, residual drift approximation, regional-residual field separation, source depth estimation, and modelling.

Automation of the cultivation process in term of program control of temperature and moisture
Beneš, Vojtěch ; Papežová, Stanislava (advisor) ; Neděla, René (referee)
Theoretical part of this thesis describes different kinds of sensors used for measuring temperature and humidity of air. These sensors are categorized according to the principle on which they operate. It also describes their characteristics like range, accuracy and other aspects important for determining suitability for a glasshouse automation system.
Practical part of this work covers design of this system which can be used for auto-mated controll over temperature and humidity. It reasons about suitability of different kinds of sensors and materials. It also describes a software system capable of maintaining and changing humidity and temperature based on user input. Results of different mea-surements done during the system's operation in a variable environment are evaluated to draw conclusions about the system's ability to maintain constant temperature and humidi-ty levels inside the glasshouse.

Czech Electronic Toll System
Beneš, Vojtěch ; Zelený, Lubomír (advisor) ; Černohorský, Jan (referee)
The goal of the thesis is to give reader a detailed description of the Czech electronic toll system with emphasis to the potential future system development and infrastructure toll extension. The National Transportation Policy, legislative framework concerning the infrastructure tolling, and particular European toll systems are described in the first part of the thesis. Within the other part of the thesis, the reader is given a simplified cost-profit model of future toll extension efficiency to evaluate the optimal outcome of the toll extension.
