Utilization of inverse reliability analysis tools for probability based design of selected structural parameters
Lipowczan, Martin ; Novák, Drahomír (referee) ; Lehký, David (advisor)
This bachelor thesis deals with the application of methodology and tools of inverse analysis in regards to probabilistic design of selected design parameters of structure. The first step was to get familiar with the probabilistic design and analysis, then understanding of the inverse analysis methodology itself which is based on artificial neural networks. After researching the topic we could get to the actual issue. To put the theory in practice easier examples were used at first. These were mathematical functions and one practical-based example, whereas the results were known in advance. This simplified a process of checking achieved values. Using software tools and especially DLNNET software allowed us to take on practical exercises. Used exercises are chosen from earlier undergraduate studies at the Faculty of Civil Engineering, Brno. The first of these was a design of reinforced concrete slab, where desired parameters were slab’s height and area of reinforcement. The second one was a design of a diagonal truss screw connection, aimed to size the screw diameter and its quantity.

Vyhodnocení variabilní aplikace hnojiv ve vybraném zemědělském podniku
Necid, Václav
Precision agriculture with a focus on variable fertilization offers a sustainable approach to optimizing crop yields and minimizing environmental impact. This study aims to explore and evaluate the effectiveness of variable fertilizer application, assess its potential impacts on future agriculture, and guide sustainable and profitable agricultural practices. The objectives of this work include an extensive literature review on precision agriculture, plant nutrition with phosphorus and potassium, as well as an evaluation of the benefits of variable application of phosphate and potassium fertilizers. Field trials conducted between 2019 and 2021 on selected agricultural land with a total area of 103.09 hectares involved soil sample collection and the processing of results using the IDW interpolation method. In 2019 and 2020, variable application of stock fertilizers TSP (Triple Superphosphate) and DS (Potassium Salt) was carried out according to the created application maps and the given nutrient recommendation for the main cultivated crop, with a correction of the nutrient supply dose in the soil. The application was carried out using a Terra-Gator 8203 machine and an AirMax 2000 pneumatic spreader. Thanks to the RTK system and RAVEN GPS navigation, it was possible to achieve precise and uniform fertilizer application. The thesis includes an evaluation and determination of the value of spatial unevenness (coefficient of variation) of the land, indicating that targeted variable fertilizer application leads to a leveling of agrochemical properties of the soil. The economic evaluation of variable application showed that the yields of harvested crops were higher than the company's average, indicating efficient fertilizer use. The conclusion of the work compares the differences in costs between uniform and variable application.

Personal characteristics of speech rhythm in Russian newsreading
Čížková, Irena ; Volín, Jan (advisor) ; Veroňková, Jitka (referee)
Personal characteristics of speech rhythm in Russian newsreading Bc. Irena Čížková Abstract An issue of individual rhythmic characteristics of particular 5 native speakers of the Russian language, newsreaders from the BBC, is described in this thesis. A research of the given 5 speech recordings was conducted based on the academic concepts created by Ramus, Mehler and Nespor, and by Low and Grabe and also by Dellwo, so through a speech rhythm research based on rhythm correlates that are related to vocalic and intervocalic intervals. The recordings were processed in an analyting program called Praat and the extracted results were then evaluated in a statistical processor called STATISTICA. These materials were used for further analysis. The recordings were analysed based on several parameters: %V (proportion of vocalic intervals in one breath group), ∆C and ∆V (standard deviation of the vocalic and consonantal interval duration), PVI-V, PVI-C (Pairwise Variability Index of the vocalic and consonantal interval duration), Varco V and Varco C (variation coefficient of the vocalic and consonantal interval duration) and the difference between duration of stressed and unstressed vowels. Three parameters that were the most successful from the speakers' ability to differentiate point of view were selected through an...

Vývoj regionálních disparit České republiky v období 2007-2016
Košárková, Petra
The main goal of the bachelor thesis is to evaluate the level of regional disparities in the Czech Republic in the period 2007-2016. Specifically, the bachelor thesis is focused on czech regions. The theoretical part deals with the issue of regional disparities with the outline of their solutions. For the purpose of the thesis, the point method is chosen in the practical part, which formulates the individual order of the regions based on the index of economic disparities. In order to determine the degree of convergence of individual regions over time, the thesis also uses the coefficient of variation of economic disparities indices. The best rated region is Jihomoravský, Ústecký is the worst. In czech regions, there was considerable convergence only in 2008-2001, this convergence could have been affected by the economic crisis.

Changes in the tax mix in EU Member States
BERANOVÁ, Monika
Diploma thesis deals with the tax mix development in member states of the European Union. One of the EU goals is to harmonize tax system of individual member states to ensure better functioning of united market inside the European Union. Due to this reason changes in tax mixes of member states happen. The main aim of this thesis is to ascertain changes on the share of revenues of individual taxes on total tax revenue during the given time period in member states of the EU, to identify groups of similar states and try to explain the results using chosen economical indicators. A cluster analysis was used to analyse the development of Member states' tax mixes in 1995, 2002 and 2015. The cluster analysis resulted in a definition of groups of states where the composition of the tax mix is most similar. Using the variation coefficient, a change in the share of selected taxes in total tax revenue between 1995, 2002 and 2015 was subsequently described. Source data were taken from the Eurostat database. Analysis of variation coefficients did not confirm the convergence of tax mix across the European Union. Only after the breakdown of the Member States into the original 15 Member States and those that have joined the EU since 2004 convergence has emerged. But these trends are not so marked.

Political Aspeckts of Local Government – Comunal Elections and Preferential Voting
Čermáková, Kristýna ; Kopřiva, Radek (advisor) ; Lenka, Lenka (referee)
The thesis is divided into two parts, theoretical and practical. Theoretical part introduces and explains basic concepts of local politics, with detail characteristic of municipalities, municipal elections and preferential voting. This part is also concerned with research of local politics by published expert articles. This part is researched through the legislation and political expert literature.
The practical part is focused on demographicaland socioeconomical description of district Benešov. The main part of thesis is the analysis of the voting results in the local elections of the municipalities in the district Benešov in 2014, particularly the preferred votes of candidates aspiring to gain a political seat with a mandate .
