Treasure islands: the economic analysis of tax havens
Filip, Ondřej ; Janský, Petr (advisor) ; Adam, Tomáš (referee)
Bachelor Thesis Abstract This thesis strives to introduce a wider notion of tax havens. We alter a traditional paradigm by investigating tax havens' influence on economic performance of other countries. The first part of the thesis copes with issues implied by the absence of a suitable tax haven's definition which results in compiling an inclusive list of havens. Subsequently, we present a data-based description of the identified tax havens with an emphasis on several widely-held assertions. The second part delivers an empirical analysis. It illustrates the role of tax havens as financial intermediaries. We examined whether the volumes of capital flows between non-havens and tax havens correspond to the sizes of the counterpart economies and to their mutual distance. Foremost, we found intensified capital flows between tax havens and large non-haven countries in their close proximity. The thesis concludes by a discussion of results.

Princip bezpečného vzdáleného ovládání zařízení pomocí mobilní aplikace
FILIP, Ondřej
The bachelor thesis deals with designing and describing the principle of secure wireless communication assembled system of heterogeneous devices with developed user mobile application in the context of the use in independent home automation environment. This system device consists of a modular executive unit, which is implemented by using devices from Texas Instruments. It also consists of a server unit, which is used for local communication with executive unit and for external communication with mobile application. Mobile application has basic functions for controlling and monitoring status of the executive unit.

Compact directed acyclic word graph in a sliding window
Filip, Ondřej ; Dvořák, Tomáš (advisor) ; Senft, Martin (referee)
Compact directed acyclic word graph (CDAWG) is the space-efficient version of a text-indexing data structure called suffix tree. The goal of this work is an implementation and comparison of algorithms constructing CDAWG for text in a sliding window. Sliding window is favorable in cases when the index structure cannot be kept in memory for the whole indexed data. One exact move of the sliding window may be performed in linear time with respect to the length of the window. An approximative algorithm requiring only amortized constant time per one move has been developed, too. However, in this thesis, the correctness of this algorithm has been disproved.

Food vs. Fuel: The Role of Bioenergy
Filip, Ondřej ; Janda, Karel (advisor) ; Pertold-Gebicka, Barbara (referee)
Bibliographic entry Filip, O. (2015): "Food vs. Fuel: The Role of Bioenergy." (Unpublished master's thesis). Charles University in Prague. Supervisor: prof. Ing. Karel Janda M.A., Dr., Ph. D. Length: 121,976 characters Abstract This thesis studies the relationship between the first generation biofuels and selected commodities and assets in the USA, Europe, and Brazil. It is the first attempt to combine the taxonomy and wavelet analyses in a single research application. Our unique dataset comprises 32 weekly price series covering the 2003-2015 time period. First, we employ a method of minimum spanning trees and hierarchical trees to model a biofuel-related price network. We demonstrate a development phase shift between Brazilian and the US/EU biofuel industries. We reveal a strong and stable connection between Brazilian ethanol and its main production factor, local sugarcane. We further find that US ethanol is closely linked to corn. In the contrary, European biodiesel exhibits only moderate ties to its production factors. Subsequent wavelet analysis scrutinizes the identified price connections both in time and frequency domains. Both Brazilian and US ethanols are found to be positively related to their respective feedstock commodities. In particular, feedstock proves to lead the price of the biofuel and not...

An analysis of the international mobile digital distribution platforms market
Štěpánek, Jaroslav ; Sedláček, Jiří (advisor) ; Filip, Ondřej (referee)
The main subject of this diploma thesis is the mobile digital distribution market. The first chapter defines important terms and describes the area comprehensively. The second chapter lists examples of some platforms, shows statistical data and introduces common business models. The third chapter compares the Apple App Store and Google Play based on selected criteria. The fourth chapter deals with conducted survey data in order to test the hypothesis that czech consumers in general do not show a difference in attitude towards mobile distribution storefronts compared to their foreign peers. The fifth and last chapter tries to analyze technical backgrounds of varying content availability across different countries. Also, it deals with selected legal issues.
