Hamiltonian cycles in cubic graphs
Melka, Jakub ; Pergel, Martin (referee) ; Kratochvíl, Jan (advisor)
In this work we study the complextity of Thomasson's algorithm over a special class of cubic graphs. This algorithm nds another hamiltonian circuit, if it starts with a rst one. An open problem is the complexity of this algorithm, but a class of cubic graphs has been found, where for each graph in this class, there exists a hamiltonian circuit and an edge on it, for which Thomasson's algorithm needs exponential number of steps. The goal of this work was to gure out, if Thomasson's algorithm needs exponential number of steps for any hamiltonian circuit and any edge on graphs from this class. We succeeded in proving, that indeed is so.

True Money Supply
Dufek, Michal ; Písař, Pavel (advisor) ; Czesaný, Slavoj (referee)
This thesis deals with the real money supply (True Money Supply). Monetary aggregates (M1, M2, M3) used in mainstream economics is that, in many respects inaccurate and therefore unsuitable. TMS monetary aggregates are preferable aggregates M1, M2, M3, because it counted some of the cash items twice, unlike M1, M2, M3, and therefore more accurately reflects the evolution in monetary economics. The aim of this work is based on established theory of money, count the real money supply (TMS1, TMS2) and investigate its characteristics and relationship with respect to selected economic indicators, which are: the monetary aggregate M2, the consumer price index (CPI), industrial producer price index (PPI), the discount rate, two-week repo rate, index of the Prague Stock Exchange (PX), the total volume of loans. Confrontation between TMS1 and TMS2 with selected economic indicators, can lead to a more accurate understanding of the causes of changes in the economy over the economic cycle. The theoretical part is to define the concept of money, creation, development, development of the banking system; commodity mode and paper (FIAT) money. The analytical part will try to uncover hidden phenomena and causal relationships between the real money supply and the development of the economy. The work is based on the methodology of the Austrian School of Economics, whose praxeologie seems to me the most because of its clarity and consistency. Without this theory, we could not understand the question: What else is money and what is not?

Thermal analysis of interaction of epidermal lipids IV
Komárková, Radka ; Musilová, Marie (advisor) ; Doležal, Pavel (referee)
Thermal analysis of interaction of epidermal lipids IV Radka Komárková, diploma paper, June 2009 Abstract Main function of skin is protect organism in face of chemical and mechanical damage. Skin is composed of several layers, and most considerable barrier of which forges most upper part stratum corneum. Stratum corneum contains cells fill in with keratin, which are surrounded lipid matrix. Main components of lipid matrix are ceramides (50%), cholesterol (25%) and fatty acids (10%). At present are many experimental works specialized up to preperation in vitro lipid membrane and aim of our work is find out, whether concentration of water can influence hydration lipophilic components of lipid membrane. We used samples, which had constant composition lipid mixture (cholesterol : ceramid 14S24, 1:5) and they differentiated content of water (75%, 50% and 25%). This samples were remit to several cycles of cool down and warming up by the help of DSC, where was establishment only one mixed peak of lipid mixture. All samples showed out interaction with water, however sample with 25% substantiality, it was rather on limits of analytic mistake.

Biomechanics of pedaling as a determinant for the performance in the cycling part in the triathlon
Svatoš, Václav ; Kovářová, Lenka (advisor) ; Horčic, Josef (referee)
Tittle: Biomechanics of pedaling as a determinant for the performance in the cycling part in the triathlon Objective: Prove that mastering pedaling technique, means higher performance in triathlon. Method: For the analysis of measured data use software SPSS, in which we use the test for two independent (paired) files. Due to the characteristics of the file, we used the Mann- Whitney test, we set the significance level at 0.05. Then we set standards for the selected test using T-points. Results: On the basis of the hypotheses, we conclude that there satisticky significant difference between groups (selection, other) the test results in the men's category (sig. 0.019). The opposite results were observed in the women's category (sig. 0.683). Performance comparison groups of men and women were different and statistically highly significant (sig. 0.000). Another result of this work is to establish standards by T - points for members of the youth sports center (YSC) in the triathlon for the assessment test at maximum cadence bicycle ergometer test in Cyclus 2. Keywords: pedaling cadence, YSC, diagnostics, maximum pedaling cadence test, Mann- Whitney test

Which factors limit the distribution of the hemiparasitic plant \kur{Rhinanthus minor}?
BLAŽEK, Petr
Populations of the hemiparasitic plant Rhinanthus minor are declining recently. The decline is probably caused by changing agricultural practices. Using a seed sowing experiment, I tried to demonstrate the dispersal limitation of this species, and at the same time, I examined several possible factors that could limit the Rhinanthus minor distribution. I found that seedlings of Rhinanthus minor can establish well in quite wet sites with low amount of litter and nutrients. This corresponds to meadows that are regularly mown. However, due to its annual life cycle and lack of persistent seed bank, mowing at the time of flowering could be detrimental for Rhinanthus minor populations.

Performance in Software Development Cycle: Regression Benchmarking
Kalibera, Tomáš ; Tůma, Petr (advisor) ; Hauswirth, Matthias (referee) ; Eeckhout, Lieven (referee)
The development cycle of large software is necessarily prone to introducing software errors that are hard to find and fix. Automated regular testing (regression testing) is a popular method used to reduce the cost of finding and fixing functionality errors, but it neglects software performance. The thesis focuses on performance errors, enabling automated detection of performance changes during software development (regression benchmarking). The key investigated problem is non-determinism in computer systems, which causes performance fluctuations. The problem is addressed by a novel benchmarking methodology based on statistical methods. The methodology is evaluated on a large open-source project Mono, detecting daily performance changes since August 2004, and on open-source CORBA implementations omniORB and TAO. The benchmark automation is a complex task in itself. As suggested by experience with compilation of weather forecast model Arpege/Aladin and implementation of component model SOFA, large systems place distinguishing demands on tasks such as automated compilation or execution. Complemented by experience from Mono benchmarking, the thesis proposes an architecture of a generic environment for automated regression benchmarking. The environment is being implemented by master students under supervision of...

Pyramid causeway in the Old Kingdom: evolution of the architecture and definition of the relief decoration program
El - Awadí, Tárek Mohamed ; Verner, Miroslav (advisor) ; Bárta, Miroslav (referee) ; Charvát, Petr (referee)
In the spring of 1994, an unexpected discovery to the North of the upper part of Sahure's causeway changed the long established belief that the mortuary complex of Sahure was excavated completely by L. Borchardt.1 Four huge limestone blocks decorated in basrelief of the highest quality bearing unique polychrome scenes were discovered during that spring, proving Borchardt's excavations of Sahure's complex were incomplete. These four blocks were evidence that more decorated blocks and fragments were still under the masses of sand surrounding the upper part of the causeway which had never been investigated by Borchardt? This surprising discovery was the result of cleaning being done in the area in preparation to open the Abusir necropolis for tourists. The work was under the supervision of Zahi Hawass. Hawass stopped the work at Abusir and reburied the blocks after they were photographed and drawn with the help of the Czech mission working at Abusir. Only a preliminary report was published by Zahi Hawass and Miroslav Verner to present the discovery to scholars.3 In their report, a survey of the causeways from royal funerary complexes was performed to alert scholars that many causeways are partially or completely unexcavated and need to be given more attention.4 In 2002, the present author was trusted by Hawass...

Maturity mismatching and its impact on the yield curve
Němec, Petr ; Potužák, Pavel (advisor) ; Janíčko, Martin (referee)
This diploma thesis deals with a new discord in the Austrian economic theory about the effects of maturity mismatching practiced by banks on the shape of the yield curve and defines the not yet established concept of the natural yield curve. The conflicting contributions of Austrian authors are compared for that purpose. Based on this comparison, a coherent theory of the effects of maturity mismatching is presented in a framework of the loanable funds market. A definition of the natural yield curve is then produced by a synthesis of the above-mentioned findings and the Austrian theory of the natural rate of interest. Theoretical research leads to the conclusion that one form of maturity mismatching inevitably results in an Austrian business cycle. The empirical section examines the question of yield curve´s behavior under the influence of maturity mismatching. An explanation concerning the selected hypotheses and their lack of confirmation is given.
