The thesis is focused on valuation of ABC a.s. with the help of the yield method. The thesis is divided into three main parts - theoretical, analytical and empirical. The objective of the theoretical part is to define basic terms used in the valuation, description of the basic procedure used in valuation and the outline of procedures of valuation. In the analytical part is at first introduced the chosen company, followed by strategic analysis, financial analysis, and financial plan. At last, in the empirical part, the valuation of the company itself is done, based on previous findings. The value of the company may then serve to company's owners as a basis to determine the selling price of the company in the future.

The work evaluated on the basis of commonly available data some of the implications of collection toll of highway D1 and D5. It focuses on identifying potential alternative routes by using statistics of national traffic census. On these routes it evaluates the changes of traffic safety, which can show the change of traffic intensity of trucks. Next part evaluates potential economic benefits of bypassing toll routes. In the end it notes possible scenarios of impacts extended toll zones to the above fact findings.

This doctoral thesis is focused into the area of multicarrier radio communications systems. These systems are perspective for current and incoming mobile communications and wireless networks. Advantages of multicarrier systems like better multipath propagation resistivity are redeemed by some disadvantages. The high peak to average power ratio of transmitted signal belongs to these disadvantages, for its inconvenience for high efficient power amplification. The thesis concerns with peak to average power ratio reduction methods for OFDM systems, that belongs to the most used multicarrier systems. One of the main objectives is the modification of the existing methods with the intention of complexity reduction. Following subject of interest is the analysis of suitable methods combinations possibilities for more significant peak to average power ratio reduction. One part of this thesis is research of influence of these methods on the OFDM signals with different parameters.

Master´s thesis deals with valuation of the KPS Metal a. s. company and uses income methods of business valuation. Thesis consists of two key parts. The first part describes aspects related to business valuation theoretically. In the second part all theoretic methods are applied to selected company by using strategic analysis, financial analysis and value drivers’ analysis and prognosis. According to all analysis, discounted cash flow method and economic value added method a company´s value is established to a date 1st January 2015.

This thesis deals with complex analysis of fine-grained magnesium alloy AZ91 prepared by ECAP process. Mechanical properties of investigated alloy in different states at various external conditions are compared. The structure of this material is inherently unstable therefore changes on microstructural and sub-microstructural level occur during thermal exposure and/or mechanical loading. These changes are analysed and quantified for investigated alloy in selected states in this thesis.

This diploma thesis deals with analysis of multifunctional building efficiency investment. The theoretical part describes investments and investment space, building life cycle, financing options and evaluation methods of efficiency investment. The practical part is focused on specific contract efficiency realized in Prague. Cash flow is created and payback time is counted for the individual scenarios. Net present value and internal rate of return serve as alternative indicators of efficiency investment.

This diploma thesis is focused on determining the value of the J.P.N. Cars s.r.o. company by using income-based methods at 31. 12. 2015. The value of the company is determined using the Discounted Cash Flow and Economic Value Added method.

Orthogonal frequency division multiplexing (OFDM) has become a very popular method for high-data-rate communication. However, it is well known that OFDM is plagued by a large peak-to-average power ratio (PAPR) problem. This high PAPR results in overdesigned power amplifiers, which amongst other things leads to inefficient amplifier usage, which is undesirable. Various methods have been recommended to reduce the PAPR of an OFDM transmission; however, all these methods result in a number of drawbacks. In this thesis, a novel method called offset modulation (OM-OFDM) is proposed to control the PAPR of an OFDM signal. The proposed OM-OFDM method does not result in a number of the drawbacks being experienced by current methods in the field. The theoretical bandwidth occupancy and theoretical bit error rate (BER) expression for an OM-OFDM transmission is derived. A newly applied power performance decision metric is also introduced, which can be utilised throughout the PAPR field, in order to compare various methods. The proposed OM-OFDM method appears to be similar to a well-known constant envelope OFDM (CE-OFDM) transmission. The modulation, structural and performance differences between an OM-OFDM and a CE-OFDM method are discussed. By applying the power performance decision metric, the OM-OFDM method is shown to offer significant performance gains when compared to CE-OFDM and traditional OFDM transmissions. In addition, the OM-OFDM method is able to accurately control the PAPR of a transmission for a targeted BER. By applying the power performance decision metric and complementary cumulative distribution function (CCDF), the proposed OM-OFDM method is shown to offer further performance gains when compared to existing PAPR methods, under frequency selective fading conditions. In this thesis, the OM-OFDM method has been combined with an existing active constellation extended (ACE) PAPR reduction method. To introduce a novel method called offset modulation with active constellation extension (OM-ACE), to control the PAPR of an OFDM signal. The theoretical BER expression for an OM-ACE transmission is presented and validated. Thereafter, by applying the decision metric and CCDF, the OM-ACE method is shown to offer performance improvements when compared to various PAPR methods. The use of OM-OFDM for cognitive radio applications is also investigated. Cognitive radio applications require transmissions that are easily detectable. The detection characteristics of an OM-OFDM and OFDM transmission are studied by using receiver operating characteristic curves. A derivation of a simplified theoretical closed-form expression, which relates the probability of a missed detection to the probability of a false alarm, for an unknown deterministic signal, at various signal-to-noise ratio (SNR) values is derived and validated. Previous expressions have been derived, which relate the probability of a missed detection to the probability of a false alarm. However, they have not been presented in such a generic closed-form expression that can be used for any unknown deterministic signal (for instance OFDM and OM-OFDM). Thereafter, an examination of the spectrum characteristics of an OM-OFDM transmission indicates its attractive detection characteristics. The proposed OM-OFDM method is further shown to operate at a significantly lower SNR value than an OFDM transmission, while still offering better detection characteristics than that of an OFDM transmission under Rician, Rayleigh and frequency selective fading channel conditions. In addition to its attractive PAPR properties, OM-OFDM also offers good detection characteristics for cognitive radio applications. These aspects make OM-OFDM a promising candidate for future deployment. / Thesis (PhD)--University of Pretoria, 2012. / Electrical, Electronic and Computer Engineering / unrestricted
