Biology-inspired control of a walking robot
Žák, Marek ; Musílek, Petr (referee) ; Ondráček, Tomáš (referee) ; Zbořil, František (advisor)
Mobilní roboti se stávají součástí každodenního života. Jsou konstruováni nejrůznější roboti, kteří dokáží provádět celou řadů různých úkolů nebo se pohybovat i v místech, kam lidé nemohou. Jejich využití lze najít při záchranných operacích nebo při průzkumu těžko dostupných míst na Zemi nebo ve vesmíru. Kráčiví roboti tvoří speciální kategorii mobilních robotů, protože se svými vlastnostmi výrazně odlišují od jiných typů robotů. Dokáží se pohybovat v členitém terénu, překonávat různé překážky a mohou využívat svoje končetiny k manipulaci s okolními předměty. Přestože jsou kráčiví roboti skvěle vybaveni pro pohyb v náročném terénu, jejich běžnějšímu užívání zatím brání řada faktorů. Jejich pohyb je relativně pomalý a energeticky náročný, unesou poměrně málo nákladu a jejich konstrukce je mnohem složitější v porovnání s kolovými nebo pásovými roboty. Kráčiví roboti často disponují desítkami kloubů, a jejich řízení je proto velmi složité. Tato dizertační práce popisuje návrh, konstrukci a řízením nového biologií inspirovaného šestinohého robota WHexaR (z anglického Wheeled Hexapod Robot, kolový šestinohý robot), kterého jsem postavil. Tento robot je schopen energeticky úsporného pohybu ve členitém terénu. Struktura jeho končetin je inspirována stavbou končetiny hmyzu. Robot dokáže přizpůsobit svůj pohyb okolnímu terénu. Speciální trochanterový kloub umožňuje natočení celé končetiny robota rovnoběžně s gravitačním zrychlením, což vede ke snížení spotřeby energie, zvýšení stability robota a schopnosti překonávat strmější svahy. Pro pohyb na rovné terénu je robot vybaven natočitelnými koly, díky kterým se robot může pohybovat vyšší rychlostí s nižší energetickou spotřebou než při pohybu pomocí chůze. Navržený kontrolér robota disponuje řadou reflexů, které byly pozorovány u hmyzu. Tyto reflexy zvyšují efektivitu pohybu robota ve členitém terénu a umožňují mu překonávat různé překážky. Robot byl podroben řadě experimentů, které prokázaly jeho schopnosti pohybu ve členitém a svažitém terénu.

Models of EU financial market supervision
Šťastný, Evžen ; Tichý, Luboš (advisor) ; Kohajda, Michael (referee) ; Musílek, Petr (referee)
Models of EU financial market supervision Author: JUDr. Evžen Šťastný, LL.M. This paper seeks the optimal way of supervision of a single EU financial market. The reason for my research is that, based on the development of financial markets in recent years, the interconnection of markets, modern investment instruments and the strengthening of multinational financial groups allow for quick and easy transfer of capital and risk between countries and financial sectors. This forces us to reconsider the appropriateness of the currently used supervisory model. The paper analyzes models of home state supervisor in connection with supervision on a consolidated basis and supervision of financial conglomerates, the model of a lead supervisor and a single supervisor model with the unified structure and dual structure with the Union and national supervisory authorities. As the evaluation criteria were chosen costs for financial institutions, supervisory effectiveness, consumer confidence and political acceptability. The analysis concludes that the most appropriate model of supervision of a single financial market of the European Union is the model of a single supervisory authority with the unified structure. The work is divided into eight chapters to present reasons why the issue should be examined, analyzed...

Stock Market Manipulation
Průša, Ivo ; Dědič, Jan (advisor) ; Musílek, Petr (referee) ; Kotásek, Josef (referee)
The disertation thesis deals with the market abuse through the market manipulation. Its focuses, in particular, to the merits of the regulation itself and specific regimentation. Manipulation is one of two pillars which creates the subject of the area of law dealing with market abuse. The thesis is divided into five basic parts, which are further divided into seventeen chapters. We proceed from the general definition of basic concepts, categories, and economic context to clarify a particular concept of manipulation and its operation in practice to particular subject matters of manipulation. The conclusion is then added to the list of negative description and liability arising from manipulation. The first five chapters, which are contained in Part A deals with general introductory remarks (Chapter 1), including notes dealing with the concept and methodology of the thesis, its objectives and determination of verified hypotheses (Chapters 3, 4 and 5). Chapter 2 of this part is partially devoted to the issue of terminology used in the thesis. We note here the fact the existing regulation limiting ratio of the concepts and conclude that this thesis will use principally general terms, i.e the market (instead of the concept of capital or regulated market) and instrument (instead of the term financial...

Portfolio Optimization in the German Stock Market
Bastin, Jan ; Musílek, Petr (advisor) ; Witzany, Jiří (referee) ; Budinský, Petr (referee)
The thesis focuses on the equity portfolio management with quantitative methods. We present 3 types of optimization objectives: One tries to find minimum variance portfolios, tangency portfolios and portfolios with maximized expected returns in the German stock market. It is possible to compare those investment opportunities with a market-cap weighted benchmark and an equal weighted portfolio. Expected returns of stocks are estimated with fundamental factor models. Risks of portfolios are estimated with 5 types of covariance matrices: the matrix calculated with historical returns, estimations with the single index model, Fama-French three factors model, fundamental factor model and the shrinkage method. Our results are doubled because of the demonstration of the impact of turnover constraint on portfolio performance measures (transaction costs are included in our calculations). One can see that optimized portfolios had attractive risk-return measures in the period 2005 - 2015. Benchmark and equal weighted portfolios were dominated and we consider them to be inefficient investments in our test.

Investing in technology companies
Panáček, Martin ; Musílek, Petr (advisor) ; Fleischmann, Luboš (referee)
The diploma thesis is focused on the issue of investing in information technology companies solely on the American capital market. It is divided into two parts. The first part deals with the private market. It compares the situation with the financial bubble in 2000 and with recent developments. It describes the current situation from a legal and financial point of view. It works with the term "Unicorn" for companies with valuations exceeding $ 1 billion. The second part focuses on the stock market and describes the change in the market capitalization of technology companies in relation to fundaments that are created in the private market. The diploma thesis is suitable for investors who want to invest in this type of companies, but they do not have access to the private market and therefore their only investment option is with the entry of the technology company into the stock market. The author's contribution lies in describing the current situation in the technology companies market.

Analysis and development of US and UK investment banking
Jurčišin, Rastislav ; Musílek, Petr (advisor) ; Kábrt, Tomáš (referee)
The aim of the bachelor thesis "Analysis and development of US and UK investment banking" is primarily to provide a unified view of the issue of investment banking in the global notion and then to compare its developments in England and the USA. The thesis will gradually follow the historic development of investment banking and what regulation and legislative changes has gone through until the present. The main focus of this bachelor thesis will be on the situation in the USA and England before the fall of Lehman Brothers and during the financial crisis in 2008 along with the situation that followed. At the end of this work, there is comparation of four selected banks, two from the USA and two from England, describing their different behaviors during the crisis or the bank itself, looking at different aspects, such as the country of origin.
