The design of an accurate rain gauge with the ability of real-time reading
Jílek, Jiří ; Mašek, Pavel (referee) ; Možný, Radek (advisor)
Rainfall estimation using point-to-point microwave links is a promising way to expand the rain gauge network in the future. However, this opportunistic measurement method is still in the research phase and faces several problems. This paper focuses on one of the problems of this research area, namely the insufficient number of existing rain gauges on the path of the microwave link for the correlation of measured data, by designing a portable rain gauge using data transmission to a remote server using narrowband internet of things (NB-IoT ) technology. To expand its capabilities, the device is also equipped with temperature sensors and a light level sensor. The device is designed with an emphasis on desirable low energy consumption, as it should be able to measure data even without the reach of the electrical network. The outcome of this work is the verification of the functionality of the device in a real environment and the evaluation of its suitability for the intended use case.

European Real Estate Investment Trusts: Analyzing Correlation with a DCC-GARCH Model
Jílek, Jiří ; Jandík, Tomáš (advisor) ; Vácha, Lukáš (referee)
Bibliographic Record JÍLEK, Jiří. European Real Estate Investment Trusts: Analyzing Correlation with a DCC- GARCH Model. Prague, 2012. 50 p. Master thesis (Mgr.) Charles University in Prague, Faculty of Social Sciences, Institute of Economic Studies. Supervisor: Tomáš Jandík MA MSc MRICS. Abstract The main goal of this thesis is to study the interdependencies between returns of European real estate investment trusts (REITs) and other investment asset classes such as European equities, government bonds and commodities. The thesis is divided into two parts: in the first part, we describe the necessary background that led to the emergence of first REIT structures and also provide an overview of the European REITs market. In the second part, we apply the Dynamic Conditional Correlation GARCH (DCC-GARCH) model to examine correlations between the above mentioned asset classes. The general understanding of real estate is that it provides diversification benefits to a diversified portfolio. However, our results suggest that returns of European REITs and stocks show a relatively high correlation and more importantly, the correlation increases in time. These findings have significant implications for investors and portfolio managers who seek protection for their portfolios in time of market downturns. Our results...

Evaluating monetary policy : the case of Ghana
Jílek, Jiří ; Hlaváček, Michal (advisor) ; Švarcová, Natálie (referee)
This thesis provides an overview of monetary policy in Ghana during the past two decades. A special focus is placed on assessment of inflation-targeting regime that the Bank of Ghana adopted in 2002 and became the first developing country to do so. After detecting the sources of inflation and a thorough description of monetary policy pursuit before 2002, the inflation-targeting regime is scrutinized. Despite the initial inability of the Bank of Ghana to meet its inflation targets, I consider the disinflationary process as well set. Optimistic expectations about the future success of inflation targeting, that the author of this thesis has, stems from the legislative changes that were made in 2002. Finally the credibility of the Bank of Ghana is identified as the main area for improvement.
