Webová aplikace pro analýzu a vizualizaci legislativního procesu postavená na principech Linked Data
Vondra, Vojtěch ; Nečaský, Martin (advisor) ; Knap, Tomáš (referee)
The aim of this thesis is to create a new dataset containing bills being passed in the Czech Parliament. It creates an ontology describing the legislative process and the individual stages of passing the bill. Both the dataset and ontology will use RDF to semanticize public exports provided by the Czech Chamber of Deputies. To create the ontology, it is attempted to specialize existing ontologies such as FRBR to describe data with a narrower domain. Resources representing bills are linked to other ontologies to connect the dataset into the Linked Data cloud. For practical presentation of the created dataset, new visualization plugins are programmed into Payola, an open-source Linked Data management tool, using HTML5 technologies.

Evaluation of indicators of performance and longevity in dairy herd of red Holstein cattle
VONDRA, Vojtěch
The aim of the study was to evaluate the effects selected for milk production, fertility and longevity in dairy herd of Holstein cattle (RED). Data processing for the thesis was collected from cows that ended the lactation period from 1 October 2012 to 30 September 2013, ie during the previous inspection year. From the reports were selected information on lactation, genotype, milk yield, meantime, service period, due to retirement, days of lactation and age at first calving for each cow separately. By tracking and a total of 274 cows Holstein cattle (RED) genotypes R1 (R88% or more), R2 (R76% - 87%) and R3 (R51% - 75%). There were statistically significant differences (P <0,05) milk yield of dairy cows with genotype R3, divided by lactation. When the third lactation had the highest yields (8,520 kg of milk). In the thesis was relationship between age at first calving and lifetime performance (rxy = -0,21). The relationship between age at first calving and age at retirement wasn´t demonstrated. Other differences were not statistically significant (P>0.05). The highest yield of dairy cows in the investigated group reached the second lactation (7571 kg of milk). The average time of insemination interval was 71 days, best service period amounted to dairy cows on the third and higher lactation (107 days). The average length of the interim reporting for dairy herd does not exceed the limit of 400 days. Shortest age at first calving cows reached genotype R1 and R2 (777 days). Longevity culled dairy cows in lactation was 2,8.
