Soukup, Filip ; Malý, Tomáš (advisor) ; Mahrová, Andrea (referee)
Title: Application of new trends beneath the neurophysiological patterns in sports training footballers. Objectives: The main objective of this work is the application of intervention programs based on the neurophysiological patterns of motion and determine their effectiveness. Methods: It is a methodical work, respecting the individual needs of soccer players in sports training. Players club FK Dukla Praha U16 were chosen on the basis of orthopedic disorders followed by a recommendation intervention programs into the training process. Results: We found that soccer players selected after the application of intervention programs in the training process achieved a significant improvement, especially on the muscles, on which the program was targeted . We have verified that the intervention programs in football practice could be applied. On the basis of subjective feelings footballers can say that the players perceive intervention largely as beneficial. Powered by TCPDF (www.tcpdf.org)

Electrical machines fault simulator
Krátký, Michal ; Krbal, Michal (referee) ; Šlezingr, Jan (advisor)
The goal of this bachelor’s thesis is the laboratory task focused on vibrodiagnostics of rotating electrical machines. The thesis is divided into theoretical and practical part. The theoretical part is made of information related to rotating electrical machine mainly its faults and technical diagnostics. Besides that the vibrodiagnostics is involved into the theoretical part as well. The practical part deals with the design of laboratory task focused on vibrodiagnostics of rotating electrical machines. There is shown how vibrations influence the machine during the operation. There is used asynchronous machine 1LA7080 and vibrometer MV-5L and noncontact tachometer UNI-T UT372 for this experiment. The second task is the starting current diagnostics. The starting current ofthe engine with the rotor asymmetry 1LA7080 and rotor symmetry 1LA7090 is going to be analyzed here. On these engines will be shown, how current flicks affectthe magnetic field of the engine in the air gap.

The construction of the risk surcharges for the imbalances trading on OTE market
Maštalíř, Jakub ; Brada, Jaroslav (advisor) ; Blaheta, Petr (referee)
This master thesis approaches the energy markets from the point of view of an electricity trader acting on the retail markets, in particular an electricity supplier to the end customers. The first part introduces the reader into the basic practices applied in the management process of the portfolio of end customers, which includes metering and evaluation of the real take-off, planning and prediction and, of course, final evaluation of the imbalances. Second part explains the principles of balance management in case of the entire ČEPS electrical grid, mechanics of the imbalances settlement and describes its actual setting with focus on the way it motivates the market participants for minimization of their own imbalances and therefore improvement of the overall electrical grid balance. The final part describes the basic construction of the risk surcharges, which the supplier adds to the commodity price to cover the costs caused by the existence of his end customers' imbalances. Furthermore, it is shown how the dependence on the system imbalance influences the size of the risk surcharge and the basic model is extended to include even this factor. Because the supplier does not set the surcharge at the level of individual end customer but for the entire portfolio, the functioning and power of the portfolio effect, which brings an extra savings in the imbalances settlement costs, is also explored in the final part. The possibility of dependence presence in the imbalances of individual end customers is also accounted for. For the first time in the Czech academic literature the economic problems that are faced by the electricity supplier to the end customers are examined and the analysis and solution of one important problem is provided in the full picture. However, the most important contribution of this master thesis lays in the opening of this topic to further examination on the academic ground.

Euro Area and its imbalances
Veselý, Miloslav ; Rybáček, Václav (advisor) ; Ševčíková, Michaela (referee)
This thesis deals with economical development of Euro Area and related structural imbalances and systemic weaknesses. As a region with common monetary policy Euro Area serves as a prime example of consequences of not fulfilling theoretical conditions which are needed for proper functioning of Optimal Currency Area concept. Current economical crisis fully revealed these imperfections and divergence process which deepened dtrucvtural differences between core and peripheral countries. My thesis will describe concept of Optimal Currency Area and international adjustment processes. Cardinal part of thesis will contain description and analysis of economical development of core and peripheral countries within Euro Area since its establishment to present with focus on revealed macroeconomical imbalances. Main aim is to show and analyze major economical causes of present crisis. In the end of thesis possible solutions and reforms designed to prevent similar development in the future will be presented.

Sino-american economic relations at the begining of the 21st century and their impact on the world economy.
Hanák, Jiří ; Neumann, Pavel (advisor) ; Němcová, Ingeborg (referee)
The thesis deals with sino-american economic cooperation with the emphasis on the period after 2000 and the current situation. The objective was to evaluate these relations and to analyse selected problems associated with the international trade. The thesis is dividend into six chapters. First two deal with general description of both economies and short summary of up to date relations. The third chapter concentrates on the structure of mutual trade and investment, with the emphasis on the concentration of foreign exchange in present China and its role in the U.S. federal debt. The fourth chapter targets three selected problems -- mutual cooperation within the WTO and the existing trade barriers, current Chinese exchange rate policy and the problem of unemployment and open economy. The fifth chapter targets the international trade theory, especially sustainability of long term deficit in the current account, problem of foreign debt and international investment position. The last chapter is handling with the impact of USA and China on the imbalance in the world economy and changes associated with the rise of China as the second-largest world economy.

Electricity market model of the Czech Republic
Kubát, Jan ; Pelikán, Jan (advisor) ; Kodera, Jan (referee) ; Marvan, Miroslav (referee)
A competitive electricity market has been established in many European countries including the Czech Republic. The electricity market includes a limited number of significant producers and traders, which can be described by oligopoly model. Since the electricity transmission and distribution are regulated, I consider two types of players performing in the electricity market: producers of electricity and traders, who buy electricity from producers and sell it to final customers. I derive oligopoly model with producers and traders "a la Cournot" and calculate a formula of equilibrium strategies. I use these theoretical findings to build a dynamic oligopoly model Ele. Ele is formulated as a mixed complementary problem and calibrated on data for the Czech Republic and neighbor states for several scenarios. The model was specified and calculated in GAMS software by the PATH solver. The results represent a Nash equilibrium. That means for individual producers: electricity generation, investment in new power plants construction and emission permits purchases. For traders the results are: equilibrium purchases, sales and cross-border transfers of electricity in each particular time period. Ele derives also equilibrium regional wholesale and retail electricity prices, emission permit prices and prices of cross-border auctions. Ele results point to an economic profitability of new nuclear power plants constructions. Further, I formulate a game in short-term electricity market, where I advise to Czech market participants, subjects of settlement, how much and in which circumstances to buy or sell electricity. Equilibrium results obtained through simulations based on the principle of a fictive game show that the current payment system of imbalance in the Czech Republic does not increase the risk of instability of electricity networks.

Meta-analysis of methodological artifacts of the phylogenetic imbalance.
SMRČKOVÁ, Jana
The influence of possible methodological artifacts (e.g. type of data or tree construction methods) on the tree topology was evaluated. A total of 413 phylogenetic trees was downloaded from the tree repository TreeBASE. Three indices of topology imbalance were employed, namely, Fusco & Cronk index, weighted average, and Colless index. The study reveals that methodological artifacts have probably a weak influence on the tree shape. Therefore, patterns in tree balance could reflect macroevolutionary processess, not a methodological bias.
