The purpose of this diploma thesis is to describe an application of data envelopment analysis to the performance assessment of bank branches. The bank has used, in the first half of the year 2007, two DEA models: DEA model with the purchasing power as an implicit parameter and DEA model with the economic potential as an explicit parameter. I have used for the calculations different models, which are stated in the literature, (i.e. CCR model or BCC model), because in data received from the bank was the influence of the purchasing power already involved. Next purpose of this thesis is to summarize theoretical basis of DEA models and also this theoretical basis put together with existing foreign studies.

OpenStreetMap (OSM) is the largest and objectively the most successful project from all attempts to open-source alternative to commercial map databases and projects of the official agencies. OSM is widely popular in Czech Republic, but the quality of this VGI (volunteered geographic information) dataset has not yet been studied. This master thesis evaluates several aspects of quantifiable characteristics of buildings in Prague. The objective was to primarily evaluate completeness, semantic accuracy and shape accuracy of building footprints. Data from OSM were compared with Digital map of Prague by Geoportal Prague, which is the official map resource covering the area of the city Prague. The data processing was done in ArcGIS by the ESRI company. The results show that OSM in Prague have high semantic accuracy and almost 100% completeness in terms of total area, but more than 50% of buildings are missing basic descriptive data. In terms of shape accuracy the footprints were identified by smaller amount of vertices than the footprints from Geoportal Prague and in some cases certain architectural details were missing.

This Diploma work is focused on evaluation options of quality of inquirer work in marketing research. Assigned task was founding proper indicators, which will help the agencies to assess if and how much the inquirers fulfill the requirements laid on them. First part contains the description of known standards and biases, which occur during marketing research. Bias indicators, which were the main goal to identify and formalize, are described in the second part. These indicators can serve as a guide to expose low quality inquirers. The constituent part of this work is an example of data analysis of real project, where the construction of some of these indicators has been described. This analysis confirmed the assumption that the data analysis should be inseparable part of every marketing research project, because low quality and cheating inquirers can be exposed on its base. Results presentation and suggestions for better checking of the data obtained by the inquirers in the field can help agencies to obtain more quality data and therefore make better and more trustable conclusions of market research projects.

The aim of this study is evaluation of using multi-dimensional statistical analyses methods as a tool for simulations of reliability of distribution network. Prefered methods are a cluster analysis (CLU) and a principal component analysis (PCA). CLU is used for a division of objects on the basis of their signs and a calculation of the distance between objects into groups whose characteristics should be similar. The readout can reveal a secret structure in data. PCA is used for a location of a structure in signs of multi-dimensional matrix data. Signs present separate quantities describing the given object. PCA uses a dissolution of a primary matrix data to structural and noise matrix data. It concerns the transformation of primary matrix data into new grid system of principal components. New conversion data are called a score. Principal components generating orthogonal system of new position. Distribution network from the aspect of reliability can be characterized by a number of new statistical quantities. Reliability indicators might be: interruption numbers, interruption time. Integral reliability indicators might be: system average interruption frequency index (SAIFI) and system average interruption duration index (SAIDI). In conclusion, there is a comparison of performed SAIFI simulation according to negatively binomial division and provided values from a distribution company. It is performed a test at description of sign dependences and outlet divisions.

Diplomovou práci věnuji problematice statistických metod a jejich využití při hodnocení uchazečů o zaměstnání. Konkrétně se bude jednat o aplikaci faktorové analýzy a jednofaktorové analýzy rozptylu. Diplomovou práci rozdělím na 4 části. První tři části zasvětím pouze faktorové analýze, poslední část se bude týkat výhradně analýzy rozptylu. V první části se zaměřím na průzkumovou analýzu dat, s cílem ověřit předpoklady faktorové analýzy. Nejdříve vyhledám vybočující a extrémní hodnoty jednotlivých proměnných. Následovat bude výpočet základních charakteristik proměnných, testování heteroskedasticity a vysvětlení smyslu každé z proměnných. Hlavní důraz bude kladen na testování normality jednotlivých proměnných, a to jak pomocí statistických testů, tak s využitím grafických nástrojů. Druhá část bude věnována matematickému modelu faktorové analýzy. Ve třetí části se zaměřím na samotné provedení faktorové analýzy. Jako první budu testovat předpoklady vztahující se na korelační matici. Následovat bude kompletní provedení faktorové analýzy v SPSS popř. NCSS. Nejdříve použiji metodu faktorové rotace Varimax. Pro odhady parametrů faktorového modelu použiji metodu hlavních komponent (pro výchozí řešení) a metodu hlavních os. Pro srovnání faktorové rotace Varimax provedu rovněž ortogonální faktorovou rotaci Quartimax při metodě hlavních os. Ve čtvrté části se zaměřím na jednofaktorovou analýzu rozptylu, vzhledem k tomu, že mám k dispozici proměnné věk a národnost, které jsem nevyužila ve faktorové analýze. Nejdříve opět provedu průzkumovou analýzu dat, popíšu jednofaktorový model analýzy rozptylu a posléze analýzu provedu v SPSS popř. NCSS. Pokud prokážu vliv alespoň jednoho z faktorů, budu pokračovat v hlubší analýze mnohonásobného porovnávání.

This doctoral thesis is focused on value based management. The basic principle of value based management states that the main object in an organization is value enhancement. Within an organization the concept of value based management connects activities and people participating in business processes to maintain that the resources the owners put into the business are evaluated. The essential task of value based management is to find and identify factors which contribute increasing performance and creating the value of a company, known as value drivers. The purpose of this thesis is to identify the factors which by significant amount affect the value of the mechanical engineering enterprises in the Czech Republic. In the first part of the thesis an analysis of current academic knowledge in area of value drivers is made. The base of the analysis is created by foreign resources because there is only limited amount of information in domestic literature. Besides the determination of value approach and its benefits attention is mainly paid to organizing results from value generators area. Findings of secondary resources analysis are used for own research problem. The second part of the thesis includes determination of the main objects and the research problem as well as formulation of the research questions and tested hypotheses. The third part is focused on describing methods which were used in the thesis. In the thesis was applied logical (induction – deduction, analysis – synthesis, generalization – concretaization) and empirical methods (comparsion method, quantitative research methods). Primary data was collected by using a questionnaire. Obtained data was analyzed using logarithmic decomposition of the return on equity, Boosted Trees and descriptive statistics (for example measures of location, measures of variability) and more statistical methods for analysis of statistical hypothesis (Kolmogorov-Smirnov test, Lilliefors test for normality, F-test, Student’s t-test, Chi-squared test, Fisher’s exact test, Spearman’s rank correlation coefficient). In the fourth part of the thesis the branch of manufacturing industry is characterized and the identification of performance factors is accomplished applying logarithmic decomposition of the return on equity. The other subjects of research were companies in a branch called “Manufacturing of machines and devices”. The fifth part of the thesis includes summary of findings of the prime research and its discussion. Primary data was obtained by a questionnaire survey and completed with accounting information of respondents. The findings of the research show that main determinants affecting the value of engineering companies in the Czech Republic are return on assets, profit margin, consumption, sales profitability, personnel costs and value added. The qualitative value drivers are good reputation, human resources (employees) and its characteristics, business and flexibility, performance and productivity, assets, competency responsible staff, attentiveness to requirement of customers, innovation and quality.

The main goal of this theses is to create useful methodology for data migration assessment, especially assess the quality of execution. Data migration projects are often mentioned topic but the way of assessment in the literature is missing. Methodology is based on existing information, methodologies and processes and the expert experience is included. As a part of the methodology was the tool for the evaluation which is universally applicable for various projects. Data migration process was for this purpose divided into individual activities that contain processes and their criteria, which help assess the fulfillment of the processes. This tool works by assigning weights to each criteria according which are all the processes evaluated. All the criteria should be scored by expert evaluator, who should have knowledge in the data migration area. Part of this work is also an application of methodology for the real project Implementation of new Core banking system (CBS). Based on the results and their interpretation some recommendations were made. These recommendation should improve quality of data migration.

The thesis examines impact of online user reviews, expressed in 5-star rating system, on demand for PC and video games. Used weekly data are collected from www.amazon.co.uk for period 2000 - 2012. The thesis contributes to discussion which takes place between supporters of superstar theory and supporters of long tail theory. Panel structure of the dataset referred to application of fixed effects model for estimation of basic and extended model. Both estimates proved negative influence of assigned number of stars on sales rank. Basic model estimated influence of one unit change of stars on rank by 9 positions, extended model estimated this change to be 10 positions. Quantile estimate also proved negative influence of stars on sales rank. The influence is strongest for the lowest quantile of dependent variable (tau = 0,05) representing 5 % best-selling titles, where one unit change of stars causes change of 35 positions in opposite direction. With increasing quantiles this influence decreases to zero. It proves that within the market for PC and video games online user reviews contribute to superstar effect.

The diploma thesis deals with an application of partial reliability coefficients of reliability in assessing the safety of water works. The reliability factors are the quantitative condition of the marginal equilibrium. A more detailed study of the methods of the marginal equilibrium method led to an assessment of the overall and local stability of the Vranov Dam. The baseline for the evaluation were the data provided by the Technical Surveillance (TBD) and available literature. The GeoStudio 2018 was used to calculate the loads on the Vranov waterworks. The model of the groundwater flow in the subsoil was calculated by the Seep/W module and the Sigma/W module was used to determine the local stresses. Subsequently, the selection of partial reliability coefficients and theirs subsequent application to the limit equilibrium conditions were performed. Stability assessments were complemented by calculations of safety factors. The results were compared with each other.

The traditional radiation testing of space electronics has been used for more than fifty years to support the radiation hardness assurance. Its typical goal is to ensure reliable operation of the spacecraft in the harsh environment of space. This PhD research looks into the radiation testing from a different perspective; the goal is to develop radiation testing methods that are focused not only on the reliability of the components but also on a continuous radiation-induced degradation of their performance. Such data are crucial for the understanding of the impact of radiation on the measurement uncertainty of data acquisition systems onboard research space missions.

This diploma thesis deals with the large water dams realization and their impact on the adjacent region and its development. The aim of thesis is to identify the most important effects associated with the construction of dams and analyze them. The theoretical part defines basic terms, categories of dams and the impacts of their construction, included the planning proces too. The problem is practically solved on the example of the Orlik Dam. The methods that has been used on this topic were literature review, data and available resources analysis and also there were used microhistorical approach. It can be assumed that dams have great impact on the surrounding environment, but the volume of the impact is always determined by many factors. Due to the amount of planned infrastructure projects is needed to pay extra attention for consequences of their realization considerable.

The main purpose of the diploma thesis is to determine the willingness of people visiting the Eastern Slovak dam Ružín to pay for improving water quality, namely for the environmental good. Willingness to pay is determined by questionnaire investigation the contingent valuation method. Dam is a public good, which has no owner. We all use it without someone to care for it. This use is not positive, but negative in terms of pollution, clogging of toxic sediments. The theoretical part is devoted to construction and the need to build dam as well as environmental problems, which occur at the dam. This is related to the problem of public good and "the tragedy of the commons." There are the contingent valuation method and development of the questionnaire described at the end of theoretical part. The practical part consists of the evaluation questionnaire investigation and the linear regression model in terms of the parameters under which they were created identifiers variables and point estimates. Finally, it is converted by statistical analysis of the impact of variables on the amount that people are willing to pay.

Statistical machine translation is an approach dependent particularly on huge amount of parallel bilingual data. It is used to train a translation model. The translation model works instead of a rule-based transfer; in some systems even lexical. It is believed that quality of the translation may be improved with more data for training. I have tried contrary to give less data and watch how the score of the translation changes. I selected sentence pairs to stay a part of the corpus with some key fi rst randomly, then according to sentence length ratio and finaly according to the number of word couples that a dictionary knows as translation pairs. I show that selection according to an advisable criteria slows down falling of NIST and BLEU score with decreasing size of the corpus and in some cases may tend even to better score. Decreasing the corpus size also lead to faster evaluation and less need of space. It may be useful in an implementation of the machine translation system in small devices with limited system resources.

Title: Evaluating of efficiency of Football Clubs in Premier League by Data Envelopment Analysis. Goals: The aim of the thesis is to identify the effectiveness of football clubs in the Premier League in the season 2016/2017. In the post optimization analysis evaluate, which observed clubs have been effective in transforming inputs into outputs, and which clubs have some deficiencies in this transformation. Methods: In the thesis for efficiency research, the Data Envelopment Analysis (DEA) data analysis method is used to evaluate the effectiveness of individual clubs in the Premier League. DEA determines which units are effective and what are the deviations from the effective frontier for the units that are inefficient. The measurements are made by an input- oriented CCR model and a BCC model. The CCR model assumes constant returns to scale and BCC considers variable returns to scale. Results: The result section identifies the productive efficiency of individual football clubs in the Premier League in the season 2016/2017. The effective frontier reached a total of 7 clubs in both CCR and BCC models. The average efficiency in the CCR model is 87 %. In the BCC model, the average efficiency is 91 %. As a result, the Premier League as a competition is highly efficient. Key words: data envelopment...

Thesis themed "Efficiency evaluation models and their applications" deals with mathematical models for the efficiency evaluation of comparable production units and targets the utilization of Data Envelopment Analysis (DEA) for this purpose. The thesis aims first to describe DEA models and mention possibilities of their application and then to practise the theoretical knowledge by using proper software in a factual instance. To reach this aim the thesis is composed of two parts {--} theoretical abstract and practical application. The abstract contains basic theory of DEA: fundamental principles, input data and results and description of primary, alternate and modified models. A summary of software applications that can evaluate efficiency using DEA follows. The abstract is closed with some real examples of DEA applications in practice. The second part of the thesis arose from cooperation with a fire department of a factual region of the Czech Republic. The efficiency of its 16 fire stations is compared by using a proper DEA model. A number of actions (output) and a number of employees, a level of fire equipment and an inside area (inputs) are established for each fire station on the strength of the fire department{\crq}s statistics, databases and estimations. The efficiency calculation is performed through the use of the Frontier Analyst Professional, software application specially made for the DEA analysis. Regarding the outputs uncontrollable character an input-oriented DEA model is chosen for the calculation of the fire stations efficiency. A result of the DEA efficiency analysis consists in separating the effective and ineffective fire stations of the surveyed fire department. The potential improvement (inputs decrease), necessary to reach the maximal efficiency, is proposed to each ineffective fire station. This suggestion is further adapted with respect to the real feasibility and the Czech legislative order. The practical part of the thesis is concluded with appreciation to what degree the stated targets were reached and to what degree the application of the DEA method to comparing the factual fire stations efficiency was rewarding.

The conditioning preparation of a modern player in top football is an essential part for his excellent sporting performance. The theoretical part of the thesis is focused on conditioning preparation of the player in football, his motor skills and abilities. The thesis focuses in detail on very important skills in this sport, such as speed and speed endurance. The practical part will deal with collecting the speed data of the football player. These data will be processed in both factual and statistical terms. The aim of the research will be the evaluation of the measured data. The results will be compared between the autumn and spring parts of the league, depending on the player's performance. Player data will also be compared with another player on the same position. The conclusion of the thesis is to point out that speed is often a decisive factor in many football situations, and to confirm that while improving the speed abilities, the performance of the player will also increase parallelly.
