Jílek, Petr ; Toth, Petr (advisor) ; Peková, Jitka (referee) ; Luňák, Josef (referee)
Abstract Dissertation deals with theoretical concepts and providing the basis for the use of forms of financing and acquisition of public goods and services through partnerships between the public and private sectors, as well as PPP (Public Private Partnership). Suitability PPP project in this work is assessed primarily in terms of developing a new methodology for evaluating projects. The theoretical part of the thesis aims to clarify the issue of PPPs in the context of regional and local regional development theories, principles and mechanisms of PPP legislative and institutional backing of the PPP, clarify the distinction between PPP and public procurement procedures and current assessment of PPP projects. The practical part focuses on the development of a methodology using a selection of qualitative and quantitative methods for evaluating investments and to form a complex output that will clearly and distinctly testify about the appropriateness of using the PPP method. For this purpose it is used in work processes, which are normally used for business valuation-generators values, property valuation, yield valuation, valuation based on market analysis, combining technologies and their incorporation / recast in the current assessment methodology, which is based on a Public Sector Comparator and determinants of value for money

Influence of water erosion parameters choice stand establishment in relation to the location and arrangement of the land
Faltejsková, Michaela ; Novák, Petr (advisor) ; Kumhálová, Jitka (referee)
The aim of the diploma thesis was to evaluate and assess the crop stand establishment in terms of resistance the soil to water erosion. For this purpose, a field experiment was set up in Nespeská Lhota, which consists of six different crops and methods of treatment and one control variant maintained without vegetation. Measured variables for evaluating were the surface runoff and soil washes away. There was used the rainfall simulator for measurement.
Based on the results presented in the diploma thesis a positive impact of reduced tillage on measured values of water erosion can be confirmed. The consequence is especially a reduction of erosive washes of soil and surface runoff. Also the positive effect of ground cover with organic matter was confirmed, which contributes to the better soil qualities and the soil is less prone to water erosion.

The use of fungi and their products in organic farming
Krupičková, Karolína ; Dvořák, Petr (advisor) ; Král, Martin (referee)
Current excessive use of chemicals in plant protection raises problems. Two of these problems are increased resistance of pest populations and penetration of residues of these substances in the food chain. In recent years, there is an effort to reduce the use of chemicals and replace them with biological products that are friendly to the environment.
This thesis deals with the possibility of using of fungi and preparations containing them to protect plants, instead of using chemicals. This bachelor thesis summarizes literature and studies dealing with this problem. Firstly, it deals with mycoparasitic and entomophatogenic fungi. It mentions their representatives, which are important for biological plant protection. For mycoparzitic fungi are representatives Trichoderma harzianum, Clonostachysrosea and Pythium oligandrum. There are mentioned their life cycles and bio-preparations made from them, which are used for plants protection. From entomopathogenic fungi thesis deals mainly about genera Beauveria, Hirsutella, Lecanicillium, Metarhizium, Nomuraea, Paecilomyces, Tolypocladium and Aschersonia. Beauveria, Hirsutella, Lecanicillium, Metarhizium, Nomuraea, Paecilomyces, Tolypocladium and Aschersonia. For all representatives are listed bio-preparations and their use for protecting crops against pathogens. In the bachelor thesis are mentioned products based on fungi for protecting potatoes. Most of these products are not registered in the Czech Republic, except Polyversum which contains spores of Pythium oligandrum and is used to protect the potatoes against potato late blight (Phytophthora infestans).
The majority of biological products is highly effective against crops diseases, but some biological products are effective only in laboratory conditions at optimum conditions for the given species (eg. Tolypocladium cylindrosporum).

The central banks' non-standard monetary policy: quantitative easing
Čáp, Daniel ; Koderová, Jitka (advisor) ; Osička, Štěpán (referee)
The thesis deals with non-standard monetary policies of three central banks throughout the global financial crisis. The reason for using non-standard measures was also liquidity trap when monetary policy becomes ineffective. An important milestone was collapse of investment bank Lehman Brothers in September 2008. The central banks carried out some non-standard measures before the collapse such as the emergence of new or expanding existing facilities. However, after the collapse there was panic at the financial and capital markets and market interest rate spreads rose. Central banks were forced to respond to expanding its balance sheet and reducing the monetary policy rate to zero. The main reason for increasing total assets was securities purchases by central banks. The measure, which is expanding the balance sheet is called quantitative easing. In the thesis I try to describe and compare the non-standard measures (with a focus on quantitative easing) taken by the three central banks (Bank of England, the Fed and the ECB) and answer the question whether the measures are effective and whether they can replace the standard monetary policy.

Use of hemp and its products in cosmetics and pharmacy
Žáčková, Kristýna ; Skoumalová, Petra (referee) ; Němcová, Andrea (advisor)
Hemp is a versatile usable plant which can be found in almost all branches of industry, but also in medicine. The subject of this thesis is the determination of selected active compounds of technical hemp and its products and their possible applications in cosmetics and pharmacy. In the theoretical part is worked out the summary of active compounds including their effects in cosmetics and within medical use. In the experimental part were determined certain metabolites of hemp products, while as samples were used hemp flower, leaf, seed, flour, protein and two different hemp oils. There were also prepared creams with the addition of hemp oil in which the effects on the skin were assessed. In the analyzed samples was according to the character of the material determined the content of antioxidants, saccharides, proteins, lipids including the profile of fatty acids, vitamins and chlorophylls. It was proved that hemp flower is a better antioxidant than the leaf and contains higher amounts of all of the determined active compounds with this effect. Flour and protein which are made from the seeds have different percentages of individual studied compounds, because there is a different process for their production. The highest amount of saccharides is in the flour, hemp protein preparative consists of a 50 % of protein and in the seed was the highest lipid content. In the prepared hemp creams the moisturizing effects and the ability to prevent transepidermal water loss were observed.

IP Address Activity Monitoring
Pilátová, Kateřina ; Krobot, Pavel (referee) ; Bartoš, Václav (advisor)
Poslední dobou se objem přenášených dat po síti neustále zvyšuje. K urychlení prohledávání dat je potřeba mít způsob jejich vhodné indexace. Tato bakalářská práce se zabývá tímto problémem, konkrétně ukládáním a vyhledáváním dat za účelem zjištění aktivity komunikujících IP adres. Cílem této práce je navrhnout a implementovat systém pro efektivní dlouhodobé ukládání a vizualizaci aktivity IP adres. Aktivitou je myšleno, zda daná adresa generovala provoz v daném intervalu či ne, tedy lze ji reprezentovat jediným bitem, což redukuje objem prohledávaných dat. Výsledný systém se skládá z backendu monitorujícího provoz a ukládajícího záznamy o aktivitě do uložiště a jejich parametry do konfiguračního souboru. Dále obsahuje webový server, který na základě požadavků uživatele data čte a vizualizuje ve formě obrázků. Uživatel může specifikovat oblast dat, kterou chce zkoumat podrobněji, pomocí interaktivního webového rozhraní.

Slepá separace signálů pomocí fuzzy maskování
Čermák, Jan
Paper deals with separation of source signals from their mixtures without any information about mixing environment. This problem is known as blind source separation. We focus on improving a multichannel method called time-frequency binary masking. The proposed approach is based on using a fuzzy mask instead of a binary mask. We show that the separation performance increases by employing fuzzy mask. Moreover our method reduces musical noise introduced by binary masking.

Hydrodynamic analysis of basic equipment in units for the thermal processing of wastes
Říha, Kamil ; Kilkovský, Bohuslav (referee) ; Pařízek, Tomáš (advisor)
Thermal processing of wastes is a metod, when during combustion occur reduction of wastes till 10% previous volume. The main advantage of this method is possibility to heat utilization for heat and electric production. Through thermic process develops range of pollutants (NOx, CO, SO2, HCl, HF, PCDD/F) that had to be remove from off-gas or reduced to enviromental values in agreement with laws in force [16]. For this purpose are combustion units equip with range of devices for removing this pollutans. The main task of this diploma thesis is selectoin of ctirical device in term of pressure drops. The value of pressure drop stands significant part in proposition of efficiecy off-gas fan. In increase or decrease total pressure drop consumption of electrical energy of off-gas fan is rising or going down. Change of consumption in total classification is projecting in energy utilization rate of waste where is determinate if it stands of energy utilizatoin or just incineration. In first part of diploma thesis are described in detail availability methods of off-gas cleaning where is described their principle, advanteges, disadvatages and comparison of effectivity. In second part of diploma thesis is made example model about influnce technology on value of total pressure drop. There were chosen two technologies for removing dioxins (technology of catalytic filtration REMEDIA and DeNox/DeDiox). For both technologies were made detailed analysis of pressure drops single components of these technologies. Attainment results were compared and rated with one another. For analysis these two methods were designed mathematical process in software Maple 9.5.

Barriers of rationality influencing decision making
Ječmen, Michal ; Vrbová, Lucie (advisor) ; Hájek, Jiří (referee)
The aim of this thesis is thanks to an executed experiment among students of Economical University in Prague identify barriers of rationality influencing decision making. For this purpose we executed a quantitative research in the form of a questionnaire specially created for this experiment that helped us test barriers of rationality in students' decision making. We examined three types of barriers: an anchor, an influence of "FOR FREE" and adding a decoy among other choices. For data evaluation we had used methods of descriptive statistics, such as mode, median and measures of variability that we subsequently used for the evaluation of data by tests of hypotheses to compare their outcome with our assumptions. We have proved the validity of the influence of the "FOR FREE", the effect of the anchor and the decoy we have not proved in this research. We also suggested the improvement of the research and options how to reduce the influence of barriers of rationality.
