Analysis, features and applications of available current mode multipliers
Miksl, Jan ; Jeřábek, Jan (referee) ; Šotner, Roman (advisor)
The diploma thesis deals with analysis, validation, measurement of parameters of the commercially available current multiplies (namely the EL2082 and EL4083) and their applications in practice. Control analysis are carried out in OrCAD PSpice program and compared with values from datasheets. Control analysis are focused on AC and DC characteristics of these active blocks. There are discusses the input impedance, the output impedance, the current gain and the possibility of electronic adjusting. The parameters of the elements were verified by measurements. Proposals for circuit applications (selective circuit, oscillator, frequency filter) with EL2082 and EL4083 are presented and analyzed in the program OrCAD. Three oscillator circuit designs are experimentally tested and the results are compared with the theoretical expectations and simulations in OrCAD. The possibility of electronic control for oscillators is examined. Also the sensitivity and the tolerance analysis are carried out. The constructional details of oscillators are presented at the end of this work.

Sensitivity analysis of costs on power outages resulting from nonadherence of custom - tailored standards of the continuity of power supply
Polák, Jiří ; Skala, Petr (referee) ; Blažek, Vladimír (advisor)
The goal of the thesis is to describe the approaches used for the regulation of the continuous supply of electric power in the selected countries of European Union and to determine the power outages costs in the specific distribution network, resulting from non-observance of the customer standards used in Great Britain, Sweden and Finland. The costs have been calculated for the entire network, as well as for the individual outputs. The thesis carries out the sensitivity analysis of the power outages costs, resulting from the breaching the supply restoration standards and the multiple interruptions standard used in the Great Britain. The costs of the individual limits are shown in the tables and the graphs. The comparison of the individual outputs according to the height of the penalty costs have been carried out on the selected set of limits. The comparison of the order of the individual outputs is then carried out for the customer standards used in Great Britain, Sweden and Finland.

Synthetic immittance dipoles using active current elements
Mráka, Michal ; Jeřábek, Jan (referee) ; Koton, Jaroslav (advisor)
This master thesis discusses the design of Synthetic immittance dipoles using active current elements. The introduction presents aktive current elemetns MO-CF and DACA as buildings blocks for analog filters that are able to process signals with frequencies up to ten megahertz. Methods of synthetic elements using active current elements design is described in this thesis.Is resulted from full addmitances net which contains one active current element Subsequently there are designed various types of frequency filters working in current mode. The functionality of designed filters was verified by computer simulation. Selected designed filter were practically verified with commercially available elelments and active element MO-CF. Measurements in the frequency domain were carried on. On all of types of filters are made sensitivity analysis.

Economic analysis of the project of a biogas power plant in the Czech Republic
Havlová, Kristýna ; Špička, Jindřich (advisor) ; Krause, Josef (referee)
In recent years, the society is more interested in the use of renewable source of energy, which is related to the establishment of biogas power plants. The aim of this thesis is to evaluate the economic benefits of investing in a particular project of biogas power plant where social impacts will not be the main indicator. In the methodological part is defined methodology (static and dynamic methods of investment decision making, sensitivity analysis). Followed by the introduction of the investor and the project. In the analytical part is evaluated the project from an economic point of view and ways of sales compared with use of biogas feed-in tariffs and green bonuses. The thesis also includes assessment of the impacts of investment from the economic, social and environmental point of view.

Analysis of correlation and sensitivity of Human development index
Staněk, Tomáš ; Mazouch, Petr (advisor) ; Vltavská, Kristýna (referee)
The Human development index is a well known composite indicator which is used worldwide to compare human development between the states and which is published every year by the United Nations Development Programme. The first part of this thesis describes the origin, dimensions and calculation of HDI, subsequently it will focuses on the sensitivity analysis and its various methods. The second part of the thesis contains the analysis of correlation of the all the HDI dimensions and of the impact of the changes of each HDI component on the final output.

Evaluation of investment project – student housing
Vecán, Viktor ; Scholleová, Hana (advisor) ; Habrnal, Marek (referee)
The aim of the thesis is to evaluate an investment in refurbishment and subsequent maintenance of the property as accommodation facilities for students, and to give investors a recommendation on whether to implement the project. A market analysis in the thesis is used to identify a suitable area for the project implementation. Next part of the thesis introduces the investment project and its parameters in line with the investor's strategy. Last part of the thesis is dedicated to the evaluation of the financial plan and a sensitivity analysis.

Business Valuation Using Simulation
Gavrylyuk, Zinayida ; Mařík, Miloš (advisor) ; Luxemburk, Patrik (referee)
The following thesis is focused on the use of Monte Carlo simulation in business valuation. It examines the theoretical context of the valuation process and simulation techniques and subsequently applies these to the valuation of Plzeňský Prazdroj, a. s. as of 31.3.2008. The aim was to explore the potential of application of Monte Carlo simulation and to interpret obtained information. There was created the valuation model and performed sensitivity analysis based on which there were identified factors which have significant impact on the value. These were further investigated and characterized in terms of probability. Following the extension of the model to include uncertainty factors there was simulated business value in relation to the variability of uncertainty factors and the result was subsequently interpreted. It was concluded that Monte Carlo simulation may be useful predominantly in search for subjective value for investor due to additional information obtained.

Investment project analysis of a biogas power plant
Halama, Adam ; Machek, Ondřej (advisor) ; Krause, Josef (referee)
The goal of this master thesis is to evaluate an investment project to a biogas power plant. The first part of the master thesis defined the essential theory needed for the capital investment decisions. There is overview of the most important investment criteria like net present value and methods and sources of project financing. In the analytical part I calculate the necessary values like revenues, operational costs and depreciation in order to find out projects cash flow. The investment is then evaluated by investment criteria. In order to make the analysis more accurate the sensitivity analysis is made. In the last part of the thesis there is an overview of results and a investment recommendation.
