Chocholouš, Vojtěch ; Šíma, Jan (advisor) ; Krause, Veronika (referee)
Title: Dynamic competitive balance of the highest football leagues in selected European countries. Objectives: The main objective of the thesis is to identify the dynamic competitive balance in the first and second leagues in selected European countries and to outline their development trend. The first sub-objective of the thesis is to compare the dynamic competitive balance of the investigated competitions with each other. The second sub-objective of the thesis is to compare the results of dynamic competitive balance with those obtained by the static method of competitive balance. Methods: This thesis calculates dynamic competiitve balance using the Pearson correlation coefficient. Results: The results show that the first leagues are usually less balanced than the second highest leagues. The result also shows that the first leagues reports an increasing tendency of competitive imbalance. The only exception is the top Polish league. On the other hand, most of the second leagues reports a decreasing tendency of competitive imbalance. The exceptions are the second Spanish and Polish leagues. The Portuguese second league appears to be the most evenly balanced competition, followed by the Spanish second league. The least balanced leagues are the First Dutch League and the First English League....
Blood pressure estimation using smartphone
Šíma, Jan ; Vítek, Martin (referee) ; Němcová, Andrea (advisor)
This diploma thesis describes an experimental cuffless measurement of systolic and diastolic blood pressure (SBP and DBP) using only a smartphone. Photoplethysmographic signal (PPG), which was measured by the smartphone camera and phonocardiographic signal (PCG), which was captured by an external microphone in the mitral valve area, were used to estimate blood pressure (BP). The BP estimate was divided into 2 parts. The first was the regression estimation of BP and comparison of several machine learning (MLR) and convolutional neural network (CNN) methods according to the use of the color channel to extract PPG from the video. The second objective was the classification of BP into the category of normotension or hypertension. The PPG signal was filtered for extraction using a bandpass filter with finite impulse response (FIR) (0,5–5 Hz) followed by feature extraction. For estimation of vascular transit time (VTT) and cardiac ejection time (ET), two main cardiac echoes S1 and S2 were detected in the PCG signal. Furthermore, raw sections of PPG signals (RGB video channels) and PCG signals of different time lengths were used for the CNN models. Among the regression approaches, the most accurate algorithm was the support vector regression (SVR) method, which achieved acceptable error according to the standards of the Association for the Advancement of Medical Instrumentation (AAMI) and the British Hypertension Society (BHS) in experimental work. The mean absolute error (MAE) was determined to be 7.64±6.87 mmHg for SBP and 5.07±4.88 mmHg for DBP. The red channel was evaluated as the most appropriate color channel for extracting PPG from the video recordings for regression estimation. For classification, the AdaBoost algorithm with weak random forest (RF) classifiers proved to be the most reliable. It achieved an F1 score of almost 80 % on the PPG features extracted from the combination of red and green color channels of the video.
UV-photochemical generation of volatile species of tellurium and other transition metals
Jeníková, Eva ; Hraníček, Jakub (advisor) ; Šíma, Jan (referee) ; Kanický, Viktor (referee)
This dissertation thesis is focused on UV-photochemical generation of volatile species of tellurium, ruthenium, rhenium and iridium coupled to methods of atomic spectrometry. In the first part, attention was paid to the optimization of parameters of UV-photochemical generation of volatile tellurium species and its application for speciation analysis of Te(IV) and Te(VI) in water samples. UV-photochemical generation was carried out in a UV-photoreactor, which consisted of a low-pressure mercury lamp wrapped with a polytetrafluoroethylene reaction coil that served as a reactor. Atomic absorption spectrometry with a continuum source of radiation and high resolution and atomization in a miniature diffusion flame were used to optimize the conditions of generation, which included the composition of the reaction medium, irradiation time and the addition of transition metals as modifiers. In order to achieve a higher sensitivity of determination, the generator was coupled to a triple quadrupole inductively coupled plasma mass spectrometer. Since efficient UV-photochemical generation of volatile species was achieved only from Te(IV), with no response from Te(VI), the feasibility of this technique for simple "non-chromatographic" speciation analysis was tested and a method for determination of Te(IV) and...
Change of market value of foreign players in selected European competetions
Do, Thanh Tung ; Šíma, Jan (advisor) ; Ruda, Tomáš (referee)
Title: Changes in the size of market values of foreign players in selected European competitions. Objectives: The changes in the market values of foreign players will be observed in ten consecutive seasons starting from 2011/12. The top football competitions from the Czech Republic, Slovakia, Austria, Poland and Hungary will be examined. Based on the results obtained, the best transfer station, or environment in which a player can prove his qualities and then move up in his career, will be determined. Method: The unit difference of all players in thousands of euros was calculated. Then the average changes of all players in each season were calculated for each country separately. The same procedure was repeated in percentages to determine the real change. For a better idea, both these values were graphically recorded. Results: The values achieved by the players in this competition were many times higher than in the other competitions. Compared to the Czech Republic on average across seasons, the result in unit terms is more than six times higher. In terms of percentage change across seasons, the measured values are more than three times higher. Poland recorded the second largest unit average growth across seasons. However, the Czech Republic is better in percentage growth across seasons. For the...

Author: Adam Štěpán Title: Business plan - competition analysis Objectives: The main objective of the bachelor thesis is to establish a strategy that will serve as the basis for the establishment of a massage centre in Liberec in the context of competition analysis. The massage centre will be newly established and therefore it is important to thoroughly analyse the competitive environment in the massage industry in Liberec. Methods: Qualitative research methods are used in this work. First there was a literature search dealing with the business plan and competition analysis, followed by a semi-structured interview. The semi-structured interview was validated by an expert. The study was carried out in Liberec on a sample of two massage centres. Porter's model of five competing forces was used to measure the competitive environment, which was modified for the massage service environment. The centres SAREMA Liberec s.r.o. and SPORT PARK MEDICAL were analyzed in detail. The results of the survey were processed into Porter's model. Based on these results, a strategy for the possible establishment of a massage centre was drawn up. Results: The investigation shows that there is competition in the massage industry in Liberec, but individual massage centres do not perceive it as a threat. The competition...

Karas, Daniel ; Šíma, Jan (advisor) ; Štědroň, Jakub (referee)
Title: Testing of model for predicting the outcome of professional tennis matches Objectives: The aim of this work is to create a simple and easy to understand model to predict tennis matches. Methods: In this thesis it was used secondary analysis of the data for gaining a relevant and current information. In this work it was emphasized on valid data, which should come from the reliable sources. Further, mathematic and statistical methods were used to obtain calculation for determination correct predictions. The obtained data were processed a then they were presented within tables. Results: The modified model based on the Low-point model, which was simplified so the general public could understand it and which used easily searchable and immediately available data, successfully predicted the tournament Australian Open 2021. At the end of the tournament we had more money on the fictitious account than at the beginning. The model was able to correctly predict 5 out of 7 matches and it was in profit when betting on the predicted winner as well as betting on the advantage of the odds. However, when the model was validated at the next two Grand Slams, this model was at loss, so we cannot designate it as long-term profitable. Keywords: tennis, prediction, bet, Australian Open, Grand Slam

Title: Quality of Sport Services at Relax active club Teplice Objectives: The aim of this work is to evaluate the quality of sport services offered by Relax sport club Teplice. The secondary aim is to figure out the problematic points of service, which can lead to improving services offered to the clients and therefore improving their satisfaction. Methods: This thesis used a written form of inquiry, using the Likert scale to evaluate the fifth gap in the Gap model of service quality. A modified version of the SERVQUAL method for measuring quality of services was used, which was expanded from the original 5 dimensions into seven. The added dimensions were used because of the clubs focus on extensive options of service and a wide range of customers. Results: The survey identified the gaps between customer expectations and actual perceived value, which were used to determine problematic areas of the quality of services provided by Relax sport club Teplice. The results were positive. Tangibles, reliability, and responsible approach were the dimensions with the worst score. The SERV-score for tangibles was -2,85, for reliability -3,88 and for responsible approach -3,25. The survey revealed a problem in communication between the club and its clients. Positively evaluated was the wide range of services...

Zelinka, David ; Šíma, Jan (advisor) ; Krause, Veronika (referee)
Title: The impact of the Covid-19 pandemic on the budgets of selected clubs in the Premier League Objectives: The aim of this thesis is to determine the impact of the Covid-19 pandemic on the budgets and management of selected clubs in the Premier League. Methods: Qualitative methods of data collection were used in the thesis. Specifically, the method of document analysis (examination) and the method of data envelopment analysis DEA were used. The results were captured using graphs and tables. Results: The collected data revealed the disparate impact of the pandemic on the budgets of selected clubs in the Premier League. In absolute terms, the pandemic has hit the big six clubs hardest. The loss of revenue from ticket sales represented the biggest blow to the clubs' budgets. The largest revenue component: TV rights, was not significantly affected. The commercial revenue as the third main revenue item showed overwhelmingly an upward trend despite the pandemic. The expenditure component, consisting mainly of wages and operating expenses, has generally increased for the former and decreased for the latter, notwithstanding the pandemic. The DEA analysis found out that the least efficient teams (Everton FC, Crystal Palace FC) often recorded the loss in the seasons prior to the pandemic. This indicates...
