Side current channel of microprocessors
Obručník, Ondřej ; Hanák, Pavel (referee) ; Martinásek, Zdeněk (advisor)
In this masters's thesis is closely studied questins of current (power) side channel. It deals with attack upon this type of side channels and methods, which can this channel analyse. Also two methods of measurements, which make possible successfully attack, are presented here. Below the work describes progress, which was used for analyse current side channel of chip PIC16F84A. This chip, which was plugged in the circuit in agreement with diagram introduced here, processes step by step variety of programs implementing always other operation, which matches concrete used instruction. In corresponding chapters are introduced resulting values and graphs, which was obtained by measurement.

Financial analysis of European companies in electroenergetic industry
Sura, David ; Marek, Petr (advisor) ; Jakoubek, Jiří (referee)
This diploma thesis focuses on providing complete characteristics of European electroenergetic industry by sample of 28 most important companies from 28 countries. Analyzing these companies, their financial results and relations to surroundings during terms from 2001 to 2010 is made by means of financial analysis, then output analysis and statistical analysis to prove relations between companies' financial results and macroeconomic and microeconomic factors. As a result of partial analyses there are several findings, of which the most interesting ones are following. Financial results were getting better during observating period, indebtedness was decreased in spite of low level of indebtedness at the beginning, however companies didn't show high profitability of their capital. Companies from southeastern part of Europe had worse results than the others. By statistical analysis there wasn't observed significant influence of prices of input commodities necessary for electricity production. On the other side the positive connection between domestic product with price index and development of these companies was found significant. During this period the decrease of portion of these companies in electricity production in domestic economies was found with average partial privatization.
