Parsing Based on Several Methods
Dolíhal, Luděk ; Goldefus, Filip (referee) ; Meduna, Alexandr (advisor)
p, li { white-space: pre-wrap; } The main goal of this work is to analyze the creation of the composite compiler. Composite compiler is in this case a szstem, which consists of more cooperating parts. My compiler is special, because its syntactic analyser consists of two parts. The work is focused on the construction of the parsers parts, on its cooperation and comunication. I will trys to scatch the teoretical backgroun of this solution. This is to be done by gramatical systems. Then I~will try to justify whether or not it is neccesary and suitable to create such a kind of parser. Last but not least I~will analyse the language, whose syntactic analyser is to be implemented by the chosen method.

EU-wide CVE Programmes: Exploring the Gap between Theory and Practice
Kaishauri, Giorgi ; Kocmanová, Markéta (advisor) ; Střítecký, Vít (referee)
Author: Giorgi Kaishauri Study programme: International Security Studies Master's thesis: EU-wide CVE Programs: Exploring the Gap between Theory and Practice Abstract The aim of this research was to determine congruence between the EU-initiated P/CVE program, CT MORSE, and prominent theoretical and empirical insights present in the academic literature on P/CVE. This research presents an exploratory qualitative study which employs a deductive approach to explore a potential gap between counter-radicalization theory and counter- radicalization practice as observed in a major EU project. The data collected and analyzed in this research suggests a partial correlation between academic insights and project's activities. Three out of eight determinants of effective P/CVE strategy discussed in the literature - community engagement, community resilience, and the role of women, are fully accounted for by the project, while the other three - dialogue, identity formation, and personnel expertise are partially present in the form of their constituting elements. Individual resilience and inclusion of former radicals receive neither implicit, nor explicit focus in the project's undertakings across the globe. Moreover, the data suggests that existing congruence is not completely arbitrary, however, a substantially deeper...

Changes of biogeochemistry in headwater areas. Aplication in experimental upper Rolava River basin.
Kočárková, Tereza ; Matoušková, Milada (advisor) ; Kujanová, Kateřina (referee)
The present bachelor thesis discusses biochemistry changes in headwater areas. The main object of the thesis is to analyze the hydro-climate factors of selected parameters of water quality monitoring in order to detect their trends and interconnections. In the first part of the thesis the literature research of the topic is presented. A short characterization of the area follows as well as the crucial gathered input data, homogenization and the data files analysis. The study is the interdependence of selected biogeochemical parameters and changes in rainfall-runnof. I have conducted my own monitoring of the selected parameters of water quality. The experimental upper Rolava River basin is located in the northwest part of the Ore Mountains in the Czech Republic. Key words: Biogeochemistry, pH, conductivity, organic substances, N, P

The ratio of second to fourth digit length and sport performance in recreational and top snowboarders
Švehla, Jakub ; Pivoňková, Věra (advisor) ; Lindová, Jitka (referee)
The second (index finger) to fourth (ring finger) digit length ratio (2D:4D) is known to be a putative marker of prenatal exposure to the testosterone. It has been reported that fetal testosterone may be critical for development of morphological and psychological traits such as quality of the cardiovascular system, visuo-spatial ability, risk-taking behavior and behavioral masculinity. Testosterone-driven attributes are associated with success in male-to- male physical competition, which may be proxied by ability in sports. Many studies have found that 2D:4D is sexually dimorphic and low (male-typical) 2D:4D ratio is associated with athletic performance. This study aims to investigate possible associations of performance in sport with 2D:4D ratio, personality characteristics (Big Five model), willing to take risks and training habits, in a sample of 57 top and 57 recreational snowboard racers. We did not find any associations between 2D:4D ratio and sport performance, no significant differences were found in 2D:4D ratio between samples. We found negative associations between agreeableness and sport performance; individuals with low agreeableness achieved higher results in the real competition of freestyle snowboarding. Low agreeableness used to be associated with aggressiveness, emulation and...

Effect of long-term fertilizer application on content of risk elements in grassland soil
Jungová, Michaela ; Hejcman, Michal (advisor) ; Pavlů, Vilém (referee)
The long-term Steinach Grassland Experiment is probably one of the oldest still-running fertilised grass experiments in continental Europe. The experiment was established on an alluvial meadow Alopecurus pratensis in southeastern Germany in 1933. The meadow was divided into 75 plots and fertilised with both mineral and organic fertilisers of differing compositions and amounts.
The aim of this study was to provide more detailed information about the effects of long-term fertilisation by natrium (N), phosphorus (P) and potassium (K) on the contents of risk elements in soil.
The effects of long-term fertilisation were investigated in the extracts of a) plant-available elements (extraction of CaCl2), b) easily mobilised elements (extraction of EDTA), c) potentially mobilisable elements (extraction of HNO3), the total concentration of elements (extraction of Aqua regia).
Concentrations of risk elements As, Cr, Cu, Fe, Mn, Ni and Zn in the soil profile has increased substantially due to the phosphorus fertilisation; however, the limits for total trace elements concentration as set by the Czech legislation have been exceeded only twice, namely in the case of As and Cd. The total concentration of As (AsT) has been exceeded only once, on the plot fertilised only by nitrogen. The assumption is that that the increased level of AsT fraction in soil was probably caused in the past by fertilising with Thomas slag which is known to contain elevated concentrations of As. However, fertilising with the phosphorus-containing fertilisers has had the opposite effect on concentrations of Mn, Ni and Zn that are easily available to plants; concentrations of these elements in the soil extraction were substantially higher. In spite of the overall concentrations of Cd being lower than the Czech legislative standards, the results on several plots fertilised by mineral and organic fertilisers containing N, P and K showed higher concentrations of Cd and in one case reached the limit value. Plots fertilised by mineral fertilisers N160P44K174 (NH4)2SO4 recorded higher Cr concentrations.
In overview, it could be stated that under various types of fertilising no substantial effects of long-term fertiliser applications on a higher content of risk elements in soil has been detected. Only two plots have exceeded the limits set by Notice 13/1994 Sb., in one case it was a total concentration of As and in another one that of Cd.
