Customer segmentation by flavours of RedBull energy drinks
Doubková, Laura ; Voráček, Josef (advisor) ; Opelík, Daniel (referee)
Author: Laura Doubková Title: Customer segmentation by flavour of Red Bull energy drinks Objectives: The main objective of this bachelor thesis is to identify customer segments based on their preferences for different flavours of Red Bull energy drinks. Methods: This thesis uses a quantitative research method. Data collection was conducted through an online questionnaire survey. The questionnaire was developed based on literature search and professional studies. The data analysis was first conducted using the elbow method to determine the optimal number of clusters for each beverage flavour. Subsequently, the clusters were identified and characterized using the K-modes clustering algorithm, which is optimized to work with categorical data. Results: The analysis showed that the choice of specific flavours of Red Bull energy drinks is influenced by various demographic, psychographic and behavioural factors. This suggests the need for a differentiated approach to each customer segment. These findings demonstrate that adequate market segmentation and targeted marketing can significantly help the Red Bull brand to meet customer needs and strengthen its competitiveness in the energy drink market. Conclusion: By analysing the differentiating factors in the choice of Red Bull energy drink flavours,...

Geographical aspects of electoral support for the populist radical right in Czechia
Cihlář, Pavel ; Lepič, Martin (advisor) ; Suchánek, Jonáš (referee)
The populist radical right parties, along with their political successes in the 21st century, have also gained considerable academic interest. Given the significant geographic variation in support of these parties, the attention is also turning to the geographical aspects of this phenomenon. These aspects are the focus of this thesis. It aims to map the intensity and shape of the clustering of electoral support for the Freedom and Direct Democracy (SPD) movement in the 2017 and 2021 parliamentary elections and to further examine geographical differences in the explanatory factors of this electoral support. The thesis uses the method of spatial autocorrelation and multiscale geographically weighted regression to achieve these objectives. The statistical units are the municipalities of the Czech Republic, and the explanatory variables are socio-demographic indicators, conceptualized according to three categories of explanatory support for the populist radical right: economic grievances, cultural grievances, and anomie. Particular attention is paid to the theory of anomie, based on theories of mass society and social capital. Earlier analyses of this theory have led to ambivalent results and this thesis tests a potential explanation for this in terms of the geographical non-stationarity of the...

Application of Mathematical and Statistical Methods in Company Management
Zezula, Lukáš ; Šustrová, Tereza (referee) ; Novotná, Veronika (advisor)
This thesis discusses the analysis of logistics costs for a company operating a network of vending machines and the subsequent minimization of the established costs by changing the locations and number of supply depots. A function reflecting the dependence of transport, warehousing, and inventory holding costs on the number and locations of depots is derived. The coefficients of this objective function are identified based on data provided by the analyzed company. Optimization of the locations and number of supply depots is performed using the Nelder and Mead iterative algorithm in combination with agglomerative clustering. The proposed approach to optimizing the logistics network is described from a mathematical-statistical and implementation perspective. Special attention is paid to finding optimal routes between supply depots and vending machines using geographic software, which also allows for measuring the route length and the time required to cover the obtained distance. The thesis then presents six proposals for reorganizing the logistics network, reflecting the optimal distribution of supply depots at their different numbers. Various shapes of the inventory holding costs are also considered, and their impact on the optimal number and locations of supply depots is discussed.

Comparison of road tax regulations in the Czech Republic and neighboring countries
PRÁŠKOVÁ, Vendula
The work focuses on comparing the adjustment of road and similar taxes in the Czech Republic and neighbouring states respectively. It describes the road tax treatment in the Czech Republic, the reasons for its introduction and the development of this tax since 1992, through relevant tax laws and regulations. Furthermore, adjustments to similar taxes on Germany, Poland, Austria and Slovakia are described in detail here. In the next part of the thesis, the criteria for cluster analysis are discussed, namely the share of road tax in the tax mix, the share of road tax in GDP and the tax burden of road tax per capita, for lower risk, all these data are taken from EUROSTAT and OECD In US dollars (USD), data on the number of motor vehicles in the region is added to expand the issue. A clustered analysis was carried out on the basis of the values of these indicators for 2012, 2021 and 2022. The result of this analysis is three dendrograms, each representing one of the years studied. Dendrograms provide a visual representation of the cluster structure and allow for the interpretation of relationships.

Analysis of AVG signals
Musil, Václav ; Sekora, Jiří (referee) ; Rozman, Jiří (advisor)
The presented thesis discusses the basic analysis methods of arteriovelocitograms. The core of this work rests in classification of signals and contribution to possibilities of noninvasive diagnostic methods for evaluation patients with peripheral ischemic occlusive arterial disease. The classification employs multivariate statistical methods and principles of neural networks. The data processing works with an angiographic verified set of arteriovelocitogram dates. The digital subtraction angiography classified them into 3 separable classes in dependence on degree of vascular stenosis. Classification AVG signals are represented in the program by the 6 parameters that are measured on 3 different places on each patient’s leg. Evaluation of disease appeared to be a comprehensive approach at signals acquired from whole patient’s leg. The sensitivity of clustering method compared with angiography is between 82.75 % and 90.90 %, specificity between 80.66 % and 88.88 %. Using neural networks sensitivity is in range of 79.06 % and 96.87 %, specificity is in range of 73.07 % and 91.30 %.
