Linear prediciton and cepstral synthesis of speech signal in the TTS system
Mekyska, Jiří ; Stejskal, Vojtěch (referee) ; Smékal, Zdeněk (advisor)
This work deals with a linear prediction and cepstral synthesis of speech signal in the TTS (Text-to-Speech) systems with the opportunity of modeling the prosody. The work contains a description of speech signal in acoustic and phonetic plane, the principle of speech production and the way we can figure the speech signal in time and frequency domain. Next, there is the TTS block structure mentioned, whereas each block has its own detailed description. In the work, the modeling of prosody using the three most important suprasegmental features (fundamental tone, continuation and speech intensity) is also described. At the end of this work, there is a design and realization of universal Czech TTS system which is based on the speech synthesis in frequency domain. This system is implemented in program MATLAB.

System engineering innovation with patent search
Mrkvan, Pavel ; Huzlík, Rostislav (referee) ; Bušov, Bohuslav (advisor)
The diploma thesis deals with engineering system innovation using TRIZ methodology. This methodology uses algorithmic approach to problem solving and divides innovation into two parts, the analysis and synthesis part. The analytical part consists of steps to help find the problem and its essence, by contrast, offers a part of synthetic procedures to deal with them. The general aim is the utilization of steps and procedures contained in the analysis and synthesis part of the TRIZ methodology to a specific engineering system innovation.

Remote Nature
Richtr, Pavel ; Suchánek, Jiří (referee) ; Krekovič, Slavomír (advisor)
In my thesis I deal with the interactivity between the weather and the virtual model, whose main output is sound. I'm trying to create generative installation where reacts virtua oraganism with real environment and generates signals that can be interpreted in a sound to explore the aesthetic relations of that connection.

Lanthanocene Catalysts for Synthesis of Polymers Applicable in Medicine
Slanina, Ondřej ; Kábelová, Božena (referee) ; Richtera, Lukáš (advisor)
The theoretic part of the thesis focuses on materials used in medicine. The metallic, ceramic, glass-ceramic and polymer materials are systematically described. The biocompatibility of the materials and possible threads of their usage for manufacturing of medicinal devices and implants are emphasized in the discussion. The work is focused especially on polymer materials. Different types of polymerizations are summarized with the accent on the preparation of biodegradable materials. In the practical part the synthesis of two organometallic bis(pentamethylcyclopentadienyl) sandwich complexes with holmium and gadolinium as a central atom designed for preparation of materials suitable for biomedicine is proposed.

Synthesis of Lanthanidocene Based Compounds
Pospíšek, Marek ; Zmrzlý, Martin (referee) ; Richtera, Lukáš (advisor)
The aim of this bachelor thesis is to summarize the issues of the polymerization catalytic systems based on lanthanidocene complexes. These complexes are subsequently divided by the structure into four basic groups. One part of this work deals with an overview of the most interesting results of the catalytic systems, which are then analyzed and assessed either in its entirety or point of view of catalytic activity, living mechanism of polymerisation and stereo or regioselectivity. The focus is also placed on type of monomers or the conditions of polymerization. In this part of thesis are also described general methods for their synthesis. Found analogies and generalization are commented from the point of view of the design of the catalytic systems for the purpose of choosing the stereo or regioselectivity, molar mass and its distribution. This gives significance to these complexes as catalytic systems for obtaining the required polymer properties. The acquired knowledge is used for the theoretical design of the catalytic system for controlled polymerization.

Modification of polyurethane by biodegradable poly(hydroxybutyrate)
Kupka, Vojtěch ; Žídek, Jan (referee) ; Vojtová, Lucy (advisor)
Cílem předložené bakalářské práce byla syntéza elastomerního polyuretanu plněného biodegradabilním polyhydroxybutyrátem. Vzorky byly podrobeny analýze morfologie pomocí rastrovací elektronové mikroskopie, mechanické vlastnosti byly testovány jednoosou tahovou zkouškou. Práce se taktéž zabývá předpovědí mechanických vlastností na základě teorií kaučukové elasticity. Bylo zjištěno, že výsledný materiál je částicový kompozit, kde se vzrůstajícím hmotnostním obsahem plniva v materiálu vzrůstá modul pružnosti. Predikce tahových křivek pomocí softwaru SEC.exe ukazovala pro reálný průběh křivky nereálné hodnoty hustot polymerních řetězců. U modelů, které vykazovaly reálné hodnoty hustot, byly naopak hodnoty napětí vyšší, než ve skutečnosti naměřené.

Synthesis of [n]Phenacenes
Jakubík, Pavel ; Církva, Vladimír ; Storch, Jan
The goal of this work was to develop a multigram scale photochemical syntesis of [n]phenacenes and their derivatives from stilbene-type precursors. Vast effort was made to examine [n]phenacenes-based organic P-type semicondutors in the past. This work is also focused on an introduction of electron-acceptor substituents (fluorine, nitrogen) into or onto phenacene skeleton. The proper choice of substitutions can lead to change in semiconductivity of [n]phenacenes so their properties could be easily modulated.

Strategic Analysis of an Enterprise
Pevný, Robert ; Kovář, František (advisor) ; Martínek, Zdeněk (referee)
This diploma thesis deals with the strategic analysis of Skoda Auto a. s. and its current strategy. Also, it deals with verifying of given hypotheses to effectively determine the future operational strategy. The first part is the theoretical and methodological, which explains the key concepts of strategic analysis of a company. It's followed by the practical part, which translates the theory of strategic analysis into the practice, analyzes modern trends and via the synthesis method it achieves the objective of this thesis: to specify strategic recommendations for Skoda Auto and to verify the hypotheses specified in the beginning.
