Detection of Dynamic Network Applications
 Juránek, Michal ; Kaštil, Jan (referee) ; Tobola, Jiří (advisor)
This thesis describes methods of detection of simple voice communications of encrypted VoIP calls between two Skype clients. The elements of network and its communication principles are described. Three approaches to classification are analyzed. The first approach performs the classification by content of network packets using Pearson's chi2 test of goodness of fit, the second approach by characteristics of network flows by means of naive Bayesian classification. The third approach describes ways of detecting signaling messages. The detector application is implemented on the basis of chosen methods.

The central bank and its function in the economy
 Guth, Karel ; Kopecká, Lenka (advisor) ; Soukup, Alexandr (referee)
The following thesis describes the importance of the central bank in the states economy and its position in the structure of the banking and financial system. It deals with its monetary policy and functions such as the role of the state bank, issuance activity or the regulation and supervision of commercial banks. The theoretical part is concluded by describing the Maastricht convergence criteria, which is built on in a questionnaire survey of the practical part. The practical part is divided into two sections. The first is focused on the exchange rate as a monetary tool of the Czech National Bank. It attempts to compare how successfully CNB has achieved its predictions from 2014 (the year when the foreign exchange interventions were initiated). The second section contains an interpretation of the results from the survey, with the aim of identifying the attitudes of Czech citizens towards adopting the euro currency. Subsequently, testing of a statistical hypothesis for contingency between selected issues was performed and connections within the columnar frequency of the contingency tables were observed and picked out.
