IT GOVERNANACE AT THE MINISTRY OF FOREIGN AFFAIRES OF THE CZECH REPUBLIC: SYSTEMIC APPROACH AND FIELD IMPLEMENTATION
Protiva, Tomáš ; Pour, Jan (advisor) ; Pilař, Luboš (referee)
The diploma thesis reacts on the interest of the Czech foreign ministry IT department to get an overview of ITIL 2 and COBIT 4.1 world-wide acknowledged IS/IT management best practice libraries. Both libraries are put in the framework of IT Governance theory and practice. COBIT is presented as world ITG standard, meaning the alignment of organization's strategic goals and IT goals. It is focused on organizations, where the shift of IT perception towards a strategic partnership with the business is driven by top-down board initiative. On the other hand, the ITIL core texts Service Support and Service Delivery are treated as a standard of IT service management, suitable as a framework to establish processes within the foreign ministry's IT department. Three alternative implementations of the two libraries are shown, in a situation of non-existent process management and information architecture. Moreover, the IT Governance initiative has a bottom-up character. The first variant connects ITIL and COBIT process models to the goals and projects outlaid in the 2008-2010 IT Strategy draft (IT BSC was used in the strategy to set up goals). The COBIT processes are aligned to the IT BSC domains and projects; further on, more detailed ITIL tools are assigned to the COBIT processes using the toolbox [IT GOVERNANCE INSTITUTE; OFFICE OF GOVERNMENT COMMERCE. Aligning COBIT, ITIL and ISO 17799 for Business Benefit]. As the projects formulated in the IT Strategy don't focus on the fundaments of process management, a stepwise approach to document the current processes using the ITIL: Service Support and Service Delivery framework is suggested. The second variant came into reality in mid 2008: COBIT has been used without success to estimate users' preferences. The reasons of the failure are discussed. Czech translation of COBIT 4.1 maturity models by the author intended to use as one of the tools in the opinion poll is attached as Annex 2. The last variant is not directly aligned to the problems of foreign ministry's IT/IS, but it is the most pragmatic guide to the implementation of the libraries. As an external help desk has been already launched, I suggest the establishment of ITIL Incident Management and Problem Management processes, supported with a CMDB configuration database.

On-line learning in real-time environments
Pacovský, Ondřej ; Spier, Emmet (advisor) ; Mrázová, Iveta (referee)
In this work, a novel reinforcement learning algorithm, Stimulus Action Reward Network (SARN), is developed. It is targeted for application in real-time domainswhere the inputs are usually continuous and adaptation must proceed on-line, without separate training periods. Another objective is to minimise the amount of problem-specific teacher(human) input needed for successful application of the algorithm. The SARN architecture combines a connectionist network and scalar reinforcement feedback by employing Hebbian principles. By adapting the network weights, connections are established between stimuli and actions that lead to positive feedback. Since the links between the input stimuli and the actions are formed quite rapidly, it is possible to use a large number of stimuli. This leads to the idea of using recurrent random network (Echo State Network) as a pre-processing layer. Prototype implementation is tested in Unreal 2004 game environment. The comparison with Q-learning shows that on the time scale of tens of seconds to minutes, SARN typically achieves better performance. When coupled with an Echo State Network, SARN requires a uniquely low amount of problem-specific information supplied by the teacher. These features make SARN useful for domains such as autonomous robot control and game AI.

Nanopatterning of Silicon Nitride Membranes
Matějka, Milan ; Krátký, Stanislav ; Řiháček, Tomáš ; Kolařík, Vladimír ; Chlumská, Jana ; Urbánek, Michal
Membranes are typically created by a thin silicon nitride (SIN) layer deposited on a silicon wafer. Both, top and bottom side of the wafer is covered by a thin layer of the silicon nitride. The principle of silicon nitride membranes preparation is based on the wet anisotropic etching of the bottom side of the silicon wafer with crystallographic orientation (100). While the basic procedure for the preparation of such membranes is well known, the nano patterning of thin membranes presents quite important challenges. This is partially due to the mechanical stress which is typically presented within such membranes. The resolution requirements of the membrane patterning have gradually increased. Advanced lithographic techniques and etching procedures had to be developed. This paper summarizes theoretical aspects, technological issues and achieved results. The application potential of silicon nitride membranes as a base for multifunctional micro system (MMS) is also\ndiscussed.

Analysis of specific instruments applied in the financial management of TNC with a focus on transfer pricing
Baluchová, Daniela ; Taušer, Josef (advisor) ; Sato, Alexej (referee) ; Baláž, Peter (referee)
Transfer pricing plays a crucial role in the financial management of TNC as it significantly influences revenues and costs allocation among affiliates of TNC that are located in countries with different tax regimes, interest rates, political situation and economic environment. Recently, transfer pricing is scrutinized in respect of tax minimisation strategies adopted by TNC which raises various conflicts of interest with tax authorities in some countries of their presence. The main objective of the dissertation thesis is to provide a comprehensive empirical study on international transfer pricing in the Czech Republic from the perspectives of both taxpayer and the tax authority. With regard to the complexity of transfer pricing, manufacturing afiliates of TNC located in the Czech Republic were selected to be examined in more detail. The thesis is structured into five chapters. The first chapter defines theoretical framework based on which the analytical part of the thesis is elaborated. The strategies applied by TNC in setting transfer prices are strongly affected by the transfer pricing regulation and interpretative experience of the particular countries in which they operate. In this context, the Czech transfer pricing legislation as well as selected case law is analyzed in the second chapter. Given the complexity of the issue of transfer pricing, the third chapter deals with selected aspects that are considered critical when setting transfer prices. The fourth chapter presents key findings regarding transfer pricing strategies applied by TNC located in the Czech Republic to transfer pricing issues. The fifth chapter summarizes the approach of the Czech tax authorities to the transfer pricing audits and at the same time evaluates related risks borne for taxpayers in this respect. The thesis reveals that manufacturing afiliates of TNC located in the Czech Republic generally prefer non market (cost based) transfer pricing methods when setting transfer prices, whereby there are several factors influencing their decision making, out of which internal economic conditions and foreign exchange risk management are deemed the most important factors, while tax optimisation as well as restrictions on profit repatriation are considered relatively less important factors. The study further indicates certain inconsistency between declared functional and risk profiles and decision making competences. In this connection, it was found out that the Czech afiliates in which the foreign parent company is involved in transfer pricing set-up incur tax losses. In response to the increasing importance of transfer pricing and international initiative Action Plan BEPS (Base Erosion and Profit Shifting) it can be stated that the approach of the Czech tax authorities has become more intensified and sophisticated. The Czech tax authorities challenge declared and actual functional and risk profile of taxpayers as well as economic substance of realized intercompany transactions. Furthermore, number of transfer pricing audits has increased and become targeted on risky taxpayers such as companies granting investment incentives or incurring tax losses etc. As a result, additional tax assessment due to incorrect transfer pricing significantly increases over recent years.

Regulation of financial markets in international context
Nistorenco, Taisia ; Žamberský, Pavel (advisor) ; Jiránková, Martina (referee)
This diploma thesis comprises a theoretical, descriptive, comparative and econometric analysis of financial markets regulation in international context. In the first chapter I describe and analyse characteristics of modern financial markets, reasons for their regulation and institutional models of financial regulation and supervision. The second chapter offers an overview of the historical development of financial regulation and evaluates the role of regulatory factor in the outburst of the world financial crisis of 2008. In the third chapter I carry out a comparison of regulatory response to financial crisis in the USA and the EU. Forth chapter deals with regression analysis of the relation between Financial Soundness Indicators of three selected countries. The conclusions driven from this diploma thesis demonstrate that regulation is generally effective as a remedy for market failures, but in other aspects its effects are ambiguous. Intensity of regulation is a secondary impact factor in the formation of financial crises, in fact it is more reasonable to state that crises occur because of the failure of supervision rather than regulation. Due to the international attempts to harmonise the process of remediation of the consequences of the financial crisis, the regulatory response in the USA and the EU was very similar. Statistical analysis did not confirm the common idea that regulation represents a significant barrier for increasing the profitability of credit institutions.

Kajzar, Vlastimil ; Kukutsch, Radovan ; Koníček, Petr ; Waclawik, Petr ; Šňupárek, Richard
Although the deformation measurements are in mining practice routine activities, the development of information and surveying technology shows, that it is possible to approach this problematics in a new way. One of the options is the application of terrestrial 3D laser scanning technology, which can be successfully used both for purposes of monitoring - deformations of objects on undermined area and mine workings at all.\nSubmited parametric study presents the use of laser technology in the research activities of the Institute of Geonics, v.v.i., within the ICT-PU project. This study deals with technical and theoretical aspects of laser scanning, which verification in situ has been a precondition for the subsequent successful application of this technology both on the surface and in the mining environment. The main scope of the study is dedicated to the deployment of selected technology in solving specific tasks. In the undermined areas were achieved knowledge used in solving the problems of monitoring the stability of slopes and rock faces of mining chasm. In the underground mine workings, this technology has been successfully deployed for the purposes of the spatial deformation monitoring of selected longwall corridor at mine Karvina and also for the long-term monitoring of coal pillars in Room and Pillar pilot project at ČSM coal mine.\nAt the end of a parametric study is special space devoted to the limiting factors of 3D laser scanning and also to the summary of best practices of scanning in such highly exposed conditions.\n
