Big Data Processing from Large IoT Networks
Benkő, Krisztián ; Podivínský, Jakub (referee) ; Krčma, Martin (advisor)
The goal of this diploma thesis is to design and develop a system for collecting, processing and storing data from large IoT networks. The developed system introduces a complex solution able to process data from various IoT networks using Apache Hadoop ecosystem. The data are real-time processed and stored in a NoSQL database, but the data are also stored in the file system for a potential later processing. The system is optimized and tested using data from IQRF network. The data stored in the NoSQL database are visualized and the system periodically generates derived predictions. Users are connected to this system via an information system, which is able to automatically generate notifications when monitored values are out of range.

Assessing Selected Indicators Using Statistical Methods
Maulová, Kristýna ; Součková, Markéta (referee) ; Doubravský, Karel (advisor)
This bachelor thesis deals with an evaluation of the financial situation of the company 2G - spol. s r.o. - Přikrývky a polštáře using statistical methods. The first part contains theoretical starting points of the thesis, which define the necessary terms of financial analysis and statistical methods, such as the method of regression analysis and time series. In the second part of the thesis, this theory is applied in practice to the mentioned company, where selected financial indicators are analyzed and prediction of future development of these indicators is determined.

The relationship between the Development of Macroeconomic Indicators and the Capital Market in CR
KLIMEŠOVÁ, Pavla
This Master's thesis is focused on an assessment of development on the capital market in the Czech Republic in the context of development of macroeconomic indicators. There are used correlation and regression analyses which indicate power of relation between variables and determine regression models. These regression models are used to predict future values. There are a gross domestic product, an unemployment rate, a consumer price index, a national deficit, an exchange rate CZK/EUR and interest rates (2W repo rate, a discount, a Lombard rate and PRIBOR) used as independent variables. Representatives of the capital market are a stock market index PX and a 10-Years Bond Yield, which are dependent variables. There is also a mention of the existence of relation between the Czech and foreign development because of globalization.

Can the stock markets predict changes in macroeconomic variables?
Vařeka, Marek ; Krištoufek, Ladislav (advisor) ; Hayat, Arshad (referee)
A bstract There is a consensus in the literature, that the stock market can predict the Gross domestic product on quarterly base or the industrial production, which is good proxy for GDP, on monthly basis and that the causal rela tionship between stock market and GDP should work both ways. However, using Vector autoregression model on US data since 1950, model shows that the stock market can not only predict the Industrial production on monthly basis, but also ISM non-manufacturing index, which is a good proxy for services in the economy. Furthermore I have managed to prove, that the unemployment can be predicted by past realizations of the stock market and managed to explain almost one third of all variations in change in un employment using S&P500 and oil prices during last 20 years. The Granger causality test concluded that stock market does cause the unemployment but not vice versa, at least during last 20 years.

China in Global and Regional policy in the 21st Century- Geopolitical Clash with Japan, India, USA, Russia, and Europe
Petrtýl, Martin ; Hnízdo, Bořivoj (advisor) ; Kofroň, Jan (referee) ; Andělová, Petra (referee)
CHINA IN GLOBAL AND REGIONAL POLITICS IN THE 21ST CENTURY - GEOPOLITICAL CLASH WITH JAPAN, INDIA, USA, RUSSIA AND EUROPE Mgr. Martin Petrtýl Supervisor: Doc. Dr. Bořivoj Hnízdo, PhD. Institute of Political Studies, Faculty of Social Sciences This dissertation discusses the current and future role of China in the 21st century. I worked with the idea to prepare a systematically detailed analytical study of the country in relation to its surroundings as well as its internal environment for more than 8 years, including many interruptions. I, above all, contemplated about the way how to truly scientifically, i.e. credibly, it means in the maximum possible the limits of verifiability, develop a full work that could hold up to the colleagues from the scientific community and myself. It is logical it was and is my attempt to allow minimal possibility of any criticism of this work for its formal, content, or other deficiencies. First, I decided to analyse in some detail the currently known theoretical approaches and methods of study, not only in political sciences, especially those used by political geographers, but also in other related fields, especially in the field of study of international relations, sociology, political science or general security studies. I did not want to study the issue is the...

Forecasting Capability of the GDP Components: Granger Causality Approach
Michalec, Jan ; Cahlík, Tomáš (advisor) ; Vozková, Karolína (referee)
This work aims to provide with the procedure of bivariate causality testing based on Granger (1969). We focused on exploration of forecasting capability of GDP components on output itself. We examine, which of five components defined in accordance with the expenditure approach can be useful in forecasting economic growth. Overall, the causal relationship is examined on national accounts data from three member states of the European Union: Austria, France and Germany. For the sake of general inference, the Granger causality tests are executed on panel data, too. We concluded, that consumption and investment possess ability to forecast economic growth. In contrast, GDP was found to be useful in forecasting government expenditures.

Fossil energy sources: prospects and environmental impacts
Klimov, Andrey ; Matějíček, Luboš (advisor) ; Přibil, Rudolf (referee)
The aim of the bachelor thesis was to describe the system of fossil fuels as non-renewable energy sources, their overall supply in the World, predictions to the future, and namely their impact on the environment. The work is a literature review, with graphic and map examples. The work focused mainly on sources of petroleum, coal, and natural gas, their total supply, and the time before depletion. From environmental aspects, the work deals with the impact of these energy sources on ecosystems. Problems and risks of the survey, extraction, and transport of fuels are mentioned, and solutions for the future, with regard to environmental protection, discussed. Key words: Fossil fuels, petroleum, coal, natural gas, predictions, environmental impacts.
