Full textAbstract:
Spinové vlny mají potenciál být použity jako nová platforma pro přenos a zpracování dat, protože mohou dosáhnout vlnových délek v rozsahu nanometrů a frekvencí v rozsahu terahertzů. K tomu, aby bylo možné navrhnout zařízení a logické obvody založené na spinových vlnách, je zapotřebí získat informace o prostorovém rozložení intenzity spinové vlny a pokud je to možné, také o jejich fázi. To lze měřit pomocí fázově rozlišeného fokuso-vaného Brillouinova rozptylu světla (µ -BLS). Předložená práce se zabývá rozšířením stávající optické sestavy o možnost měření fáze, kde doposud bylo možné měřit pouze intenzitu. Toto rozšíření sestavy je důkladně popsáno a charakterizováno. Schopnosti optické sestavy jsou demonstrovány ve studii šíření spinových vln skrz Néelovu doménovou stěnu. Získané 2D mapy intenzity spinových vln ukazují, že propagace přes doménovou stěnu je ovlivněna topologicky vynucenou kruhovou Blochovou čarou ve středu doménové stěny a že režim propagace závisí na frekvenci spinových vln. V prvním režimu propagace se vytvoří dva svazky spinových vlny šířící se kolem kruhové Blochovy čáry, zatímco ve druhém režimu se spinové vlny šíří pouze středem. Fázově rozlišené µ-BLS měření odhaluje fázový po- sun spinových vln pro oba režimy. Mikromagnetické modelování spinových vln ukazuje rozrušení jejich fázových vlnoploch, které je třeba brát v úvahu při interpretaci měření a navrhování potenciálních zařízení. Mikromagnetické simulace ukazují, že vnější magnetické pole může být použito k pohybu kruhové Blochovy čáry ve stěně domény, a tedy k manipulaci spinových vln.

This thesis concerns the technological processes of machining of thin-walled parts and the modification of said processes in dependence on the following interopera-tive measurement of the real dimensions of these parts. Within the theoretical part a research study of technological possibilities of measuring thin-walled parts and principles of probe programming are presented. In the main practical part of the the-sis a proposal of an experiment is described, which tests the individual technologi-cal steps and their influence on the quality of a prototype of the produced thin-walled part. Numerical (NC) codes are created using parametric programming, which are then used during the realization of the experiment itself. In the conclusi-on there are presented and discussed the results of measuring of the machined surfaces and the influence of correction paths, which should help to achieve a mo-re accurate production according to given dimensions. This experiment, however, has not met the expected results. That is why new procedures have been designed in order to create said paths, which can be used in a future realization of this expe-riment.

Full textAbstract:
One of the important parameters observed during extruded fibre fabrication is its diameter. The diameter can be measured with a single scanning camera assuming that the fibre section has a circular shape. As proved in practice, another important parameter is ovality, that is the rate of fibre flattening. This paper assumes that the fibre section shape is elliptical. In such a case, at least three different views on examined fibre are needed. Mathematical part of this paper is concerned with analytical description of fibre ovality measurement using two different approaches based on the knowledge of linear algebra, projective geometry and conic sections theory. Main goal of this paper is thus to use both mathematical theory and image analysis methods for ovality and diameter determination. Precise calcluation of such quantities is, however, conditioned on precise camera system calibration, which is described in the paper as well. Additionally, the work contains a brief mention of technical realization of ovality measurement and its possible difficulties.

Doctoral thesis deals with combustion engine cranktrain vibrations and vibration analysis methods. The work applies new computational models aimed at powertrain vibration decrease. The computational models can be used in the first stages of powertrain development. Temperature dependences of the rubber shear modulus and loss factor characteristic are found by response analysis of the free damped vibrations in the first part of the thesis. Viscoelastic model parameters of two dampers with different rubber hardness are calculated using optimization methods. Temperature distribution inside the rubber part during the harmonic oscillation is calculated with the knowledge of previous values. Computational models together with a user interface are assembled in Matlab/Simulink software tool. Computational model results of the viscoelastic rubber damper are verified by measurements on a prototype diesel engine in the whole operating engine speed range. Torsional vibrations of the crankshaft with torsional damper are measured by POLYTEC laser rotational tools. The temperature distribution on the damper surface is obtained by Infratec VarioCAM thermographic system. Combustion pressures in the cylinder are measured by SMETEC Combi indication tools. Both the temperature distributions and combustion pressures are used for computational purposes. All the measurement procedures are described also in the thesis.

Full textAbstract:
Vzduchem izolované vysokonapěťové rozváděče jsou nedílnou součástí energetického distribučního řetězce a to jak v průmyslovém, tak ve veřejném sektoru. Hlavní funkcí rozváděče je ochrana pracovního personálu, rozpojování/odpojování a spínání, izolování, měření proudů a napětí, chránění a ovládání zatížení a komunikace dat do řídících systémů. V každé z výše zmíněných funkcí probíhal technologický vývoj v průběhu posledních 40 let. Dnešní rozváděče jsou spolehlivé a elektrickému oblouku odolné zařízení, zoptimalizované téměř k fyzikálním limitům dielektrických, elektromagnetických a termodynamických polí. Vakuové vypínače zajišťují stálou a spolehlivou vypínací funkci. Taktéž v oblasti chránění, řízení a komunikace došlo k mnoha technologickým proměnám. Od elektromechanických relé přes zařízení založená na tranzistorech, později na jednoúčelových mikroprocesorech, až po dnešní multifunkční vysoce výkonná mikroprocesorová inteligentní elektronická zařízení. Pouze oblast měření proudů a napětí setrvala z technologického hlediska posledních 40 let beze změny. K dominujícím měřícím technologiím dneška stále ještě patří indukčně založené transformátory proudu a napětí. Byly sice provedeny některé pokusy k obměně technologie měření jako takové, nicméně bez dosažení úspěchu. Tato dizertační práce je zaměřena na poskytnutí nového náhledu na alternativní technologii měření v elektrických sítích a ve vzduchem izolovaných vysokonapěťových rozváděčích, kterou lze využít jak pro měření proudu, tak i napětí. Tato práce vysvětluje, proč Rogowského cívky, odporové a kapacitní děliče jsou tou správnou volbou a měly by být použity ve vysokonapěťových rozváděčích a podrobně analyzuje přesnost měření a jejich příslušné meze. Dále tato práce popisuje, že pro nasazování nových měřících technologií musí být postupováno systematicky. Senzory připojené k inteligentním elektronickým přístrojům a schopností komunikace založené na IEC 61850 spolu s vysokorychlostní komunikační sběrnicí Ethernetu vytvoří systém, který zjednoduší a sjednotí konstrukci rozváděčů a umožní oddělit aspekty projektování měření od studie zkratových selektivit. V práci je také uveden příklad, jak tento nový systém může přinést změny a zjednodušení do oblastí projektování a řízení. V této práci jsou popsány výsledky několikaletého úsilí při stanovení nových měřících a digitalizovaných přístupů ve vysokonapěťových rozváděčích pod autorovým vedením. Toto úsilí také vedlo k uvedení nového produktu – UniGear Digital - konceptu od ABB. Závěrečná část práce demonstruje praktické nasazení všech výsledků v této práci při skutečných aplikacích.

Full textAbstract:
The exact mechanism of the discharge in liquids ignition is not sufficiently known up to now. Although during the last years was achieved the great progress and overloading which some of them are written in this theoretical part of thesis. This thesis is divided into two experimental parts. When the first part deals with diagnostics of diaphragm discharge in electrolyte solutions and the second part is focused on its use for uncoiling (higher homogenization) of carbon nanotubes in solutions. In experiment 1, three different sized (4 l, 100 ml, 50 ml) diaphragm discharge configurations were used to diagnose diaphragm discharge in electrolyte solutions. Diagnostics is done through current and voltage waveforms with the addition of synchronized ICCD camera images that have been connected to a four-channel oscilloscope. The V-A characteristic can be described by three events occurring in the electrolyte solution with a gradual increase in voltage. Slowly increasing of the voltage in the solution leads first to electrolysis. The next phase is the formation of microbubbles or bubbles, which is characteristic of the curve by a slight decrease in the increase of the current passing between electrodes. The sudden increase in the current flow is characteristic of the last phase, namely the discharge phase. The distance of the electrodes from the diaphragm does not significantly affect the V-A characteristic. The higher diameter of the pin hole, therefore, has a higher voltage, but this does not affect the origin of bubble generation or breakdown. The higher thickness of diaphragm, the higher voltage is needed to the beginning of the bubbles generation, and consequently the discharge breakdown. Comparison of the voltage of the start generation of the bubbles and breakdown for PET diaphragms and diaphragms from the ceramic there was no mark able difference. One of the most important parameters is the conductivity of the electrolyte solution. The lower voltage is needed for the start generation of the bubbles at the higher solution conductivity, and also the discharge generation is observed at a lower breakdown voltage. The second experimental part is focused on the study of the diaphragm discharge effect on carbon nanotubes. A specially designed U-shaped reactor is used to modify carbon nanoparticles. Tap water and aqueous solutions of organic compounds are used as the electrolytic solutions. The discharge is generated by a non-pulsed DC high source with a voltage in the range of 0-2.8 kV supplied to platinum electrodes located in the electrolyte solution. The experimental results have shown that the diaphragm discharge has positive effects on the disintegration of clusters and agglomerates of carbon nanotubes. The primary effect on disintegration is probably the shock waves generated by the discharge. It turned out that it depends on the electrode configuration, where the treatment in anode space has far greater effects than the treatment in cathode half of the reactor. Effects of carbon nanotubes disintegration in solution are long-lasting and the treatment effect is not loosed after several months. There were detected no significant changes in the structure of plasma-treated nanotubes by Infra-red spectroscopy.

Increasing volume of research shows that both theoretical assumptions and empirical fit of traditional mean-variance and CAPM frameworks are flawed. Hence, other risk measures are gaining popularity. Downside risk measures not only represent the theory well, they are also significant in explaining variations of stock returns. Most importantly, the definition of risk they provide is more in line with perspectives of investors. We have carried out extensive testing on a sample of companies from the Czech Republic, Germany and Poland. Our results show that Semivariance with respect to zero is the most significant risk measure while CAPM beta by itself has little use. Finally, we also analysed importance of idiosyncratic risk on CEE shares and found out that it is indeed priced on the Czech and Polish stock markets but not in Germany.

Monika Kuchařová, Ph.D. Title of diploma thesis: Measurement of changes in mechanical properties of human skin after application of therapeutic laser This diploma thesis describes in the theoretical part the properties of human skin, the properties of laser radiation and the nature of interaction of laser radiation with human skin. The practical part deals with an in vivo measurement of changes in mechanical parameters of human skin after application of therapeutic laser radiation. The mechanical parameters of human skin were measured in ten volunteers before the application of laser radiation and then after the application. Used energy density of the laser radiation increased from 30 to 90 J·cm-2 . The observed parameters were Hooke's coefficient, Newton's coefficient and the time constant. Hooke's coefficient describes the stiffness of the skin as a whole, Newton's coefficient characterises the viscosity of the skin, the time constant is the time in which skin returns to the original state after deformation. For measurement of those parameters was used dynamic elastometer. It was found out that the changes of Hooke's and Newton's...
