Main Flaws of The Collateralized Debt Obligation‘s: Valuation Before And During The 2008/2009 Global Turmoil

As a result of the 2008 financial crisis, the world credit markets stalled significantly and raised the doubts of market participants and policymakers about the proper and fair valuation of financial derivatives and structured products such as collateralized debt obligations (CDOs). The aim of the paper is to contribute to the understanding of CDOs and shed light on CDO valuation based on data before and during the current financial upheaval. We present the One Factor Model based on a Gaussian Copula and test five hypothesizes. Based on the results we discovered four main deficiencies of the CDO market. For our modelling we used data of the CDX NA IG 5Y V3 index from 20 September 2007 until 27 February 2009 and its quotes we appropriately transform into CDO quotes. Based on the results we discovered four main deficiencies of the CDO market: i) an insufficient analysis of underlying assets by both investors and rating agencies; ii) the valuation model was usually based only on expected cash-flows when neglecting other factors such mark-to-market losses or correlation risk; iii) mispriced correlation; and finally iv) the mark-to-market valuation obligation for financial institutions should be reviewed. Based on the mentioned recommendations we conclude that the CDO market has a chance to be regenerated. However, the future CDO market would then be more conscious, driven by smarter motives rather than by poor understanding of risks involved in CDOs.collateralized debt obligations, Gaussian Copula, valuation, securitization

Media education at 2nd grade of Elementary School with a view to Civics and English language

katedra: KPP; přílohy: CD ROM; rozsah: 121This thesis deals with a new field in education and one of the cross-cutting issues, which is a media education. The thesis is divided into two main parts. In the theoretical part, the basic theories, concepts and terms such as media education are explained, its development, included in general educational programs and the expected objectives, which should meet. Also ways of implementation of media education are compared in the Czech educational system to foreign countries - with a focus on English-speaking countries. The practical part deals with the implementation of the research on media education in secondary schools and compares the implementation of media education in general educational programs.Diplomová práce se zabývá novým oborem ve vzdělávání a jedním z průřezových témat, kterým je mediální výchova. Diplomová práce je rozdělena do dvou základních částí. V teoretické části je vysvětlena základní teorie, koncepty a pojmy jako je mediální výchova, její vývoj, zařazení do Rámcových vzdělávacích programů a očekávané cíle, jaké by měla splňovat. Porovnány jsou rovněž způsoby realizace mediální výchovy v českém vzdělávacím systému se zahraničím - se zaměřením na anglicky mluvící země. Praktická část se zabývá výzkumem realizace mediální výchovy na druhém stupni základních škol a komparací realizace mediální výchovy v Rámcových vzdělávacích programech

Determination of the most suitable ratio of cathode materials for the lithium-sulfur battery system

Tématem diplomové práce jsou akumulátory lithium-síra se zaměřením na stanovení nejvhodnějšího poměru složek katodového materiálu. První dvě kapitoly poskytují úvod do problematiky elektrochemických zdrojů energie a stručný přehled nejčastěji používaných primárních a sekundárních baterií. Bližší pozornost je následně věnována lithno-iontovým akumulátorům a akumulátorům lithium-síra, v práci jsou popsány jejich principy funkce, nejčastěji používané materiály a výhody/nevýhody daných technologií. Další kapitola je zaměřena na měřicí metody, jejich principy a účel. Experimentální část práce je věnována volbě vhodného postupu přípravy elektrodové pasty a poté zejména vyhodnocení a srovnání elektrochemických vlastností vzorků s pěti rozdílnými poměry složek aktivního materiálu. Procentuální poměr síry v těchto připravených vzorcích je v rozmezí 64-88 hm. % s cílem prozkoumat vliv zvyšování obsahu aktivního materiálu na vlastnosti článků.This master's thesis deals with a topic of determination of the most suitable ratio of cathode materials for the lithium-sulfur systems. The first two chapters provide a general introduction to the topic of electrochemical energy sources and present the commonly used primary and secondary battery systems with emphasis on their characteristics and applications. The core of the theoretical part is dedicated to lithium-ion and lithium-sulfur batteries, their working principles along with the benefits or drawbacks related to the particular systems, and widely used materials. The experimental part briefly comments on determining the suitable electrode paste preparation method, the subsequent main part is focused on evaluation of electrochemical performance of cells using different ratios of cathode materials. Five samples of cathode materials were prepared, where the sulfur ratio is in range from 64 to 88 wt. %. Finally, the comparison of all prepared ratios in terms of their electrochemical properties is provided.

Electrode Materials And Electrolytes For Aluminum-Ion Accumulators

This article presents the topic of aluminum-ion batteries, which may become an available alternative to commercially used lithium-ion batteries. Theoretical part of the paper focuses on the basic principles of aluminum-ion accumulators, their advantages in comparison with lithium-ion batteries, and the current state of research on electrode materials and electrolytes for Al-ion batteries. The experimental part deals with preparation of carbon based cathode material, ionic liquid electrolyte and subsequent assembly of the electrode cell. Basic measurements were made to verify the electrochemical activity of the assembled cell. Eventually, the obtained results and following procedures or process modifications are discussed

Comparison of temperature and oxygen concentration driven aeration methods for biodrying of municipal solid waste

In this study, we used a model bio drying reactor to optimize the drying of municipal solid waste (MSW). Two methods of aeration were used: one involved controlling the concentration of oxygen (16–20%) and the other the temperature in the upper part of the reactor (temperature 42–45 °C, oxygen concentration 16– 20%). In terms of moisture content, the highest increase recorded was 0.94% and the highest decrease was 27.54%. The highest decrease in lower calorific value recorded was 9.23% and the highest increase was 41.12%. The energy balance in all the trial runs was positive. We noted that aeration using different concentrations of oxygen is strongly influenced by organic content. Thus, it is suitable only for drying wastes with known and stable compositions. The outcomes of the different methods used were influenced by ambient relative air humidity. Moisture gradients, which are often described in the literature, were not consistently reproduced in this study
