The presented thesis deals with theoretical modeling of the X-ray emission from active galactic nuclei. It studies spectral and polarisation properties of local radiation reflected from the surrounding accretion disc, which is being illuminated by a hot corona above, as well as global observational perspectives at infinity for unobscured radio-quiet sources. Modeling of this kind could then serve for observational fitting of spin of the central supermassive black hole, constraining the accretion disc's or coronal properties, or de- termining observer's inclination towards the systems. A radiative transfer Monte Carlo simulation code STOKES [Goosmann and Gaskell, 2007, Marin et al., 2012, 2015, Marin, 2018] is used for local computations. Its performance is compared to results of other attempts already existing in literature and analytical approximations. The local scheme is discussed mostly in terms of emergent polarisation that has been for the first time simulated for these types of objects with high accuracy. Integration over the accretion disc and superposition with the primary radiation in the so-called lamp-post or extended coronal model, including all general relativistic effects in the vicinity of the central super- massive black hole, is then performed on the basis of already existing routine...

This thesis studies the possibilities of education in the field of Czech cubism in museum and school environment. Czech cubism is a phenomenon that cannot be found in any other place in the world. The aim of this thesis is to bring this cultural monument and its basics to the primary and secondary schools and to the public. An educational programme is presented, that contains the theory, visual art assignments and an assignment booklet. The project is focused on realisation of our cultural tradition and visual art originality. KEY WORDS Czech cubism, architecture, applied arts, House of the Black Madonna, education, educational programme

The aim of this thesis is to analyze the major themes of female suicide bombers in Chechen widows and Tamil Tigers. For my thesis I chose empirical- analytical methodology and methodology of comparative case studies. In both cases, the first studies dealing with the historical circumstances under which the group is established, the status and role of women in society there, leading motivation to attack their targets and then mention the most important examples of attacks perpetrated by members of the terrorist group. Research suggests that in neither case is not only one motive, but rather a multi-causal phenomenon. Black widows are predominantly motivated by religious and secular motives, specifically the personal motivation because of the death of a loved one, they want revenge. In Tamil Tigers is the main motive separatist when trying to get the rights for the Tamil minority and achieve an independent state of Eelam. Despite the geographical distance and differences in religion can be proportioned to find the same in both groups. Both groups can be seen as a gender dimension - women's efforts to deal with men.

In my master thesis I realize the set of pictures and painterly objects, which should imitate principles of augmented reality by analogial form. From technical standpoint Im interested in question of bidirectional remediation of new media and painting and how its evolution supports ilussion and imagination. In ontologiacal way im looking for mystical nature of picture. Final exhibition is an metaphor composed in hybryd picture based on technological and theoretical experiences in Painting. The result is little synthetic reality.

In this work we study properties of spacetimes with a high degree of symme- try. Particularly, we focus on geometries related to higher-dimensional rotating black-hole spacetimes described by the Kerr-NUT-(A)dS metric. In the first part, we examine spacetimes admitting a separable Klein-Gordon equation. Motivated by Carter's work in four dimensions, we introduce a separable met- ric ansatz in higher dimensions. Analyzing Einstein's equations, we obtain the Kerr-NUT-(A)dS and specific Einstein-K¨ahler metrics. Then we consider a metric ansatz in the form of warped geometries of two Klein-Gordon separable metrics and classify the corresponding solutions. In the second part, we in- vestigate a class of limits of the Kerr-NUT-(A)dS spacetimes where particular roots of metric functions degenerate. Our limiting procedure results in various NUT-like and near-horizon geometries such as the higher-dimensional Taub- NUT-(A)dS spacetime. We demonstrate that the symmetries of the resulting geometries are enhanced, which is manifested by decomposition of Killing ten- sors into Killing vectors. The third part of this work deals with generalized symmetry axes of the Kerr-NUT-(A)dS spacetimes that are formed by fixed points of isometries. We show that some parts of the symmetry axes are sin- gular for nonzero NUT charges....

The subject of study of this thesis is the Kerr-Newman-(anti-)de Sitter space- time, a rotating and charged exact black-hole solution of the Einstein-Maxwell equations with a non-zero cosmological constant. In the first part of the thesis we examine admissible extremal configurations, present the corresponding Penrose diagrams, and investigate the effects of frame-dragging. In the second part, we follow the motion of charged particles via the Lagrangian formalism, focusing on the equatorial plane and the axis where we arrived at some analytic results con- cerning the trajectories. Static particles, effective potentials and - in the case of the equatorial plane - stationary circular orbits are examined. We also perform numerical simulations of particle motion to be able to check our analytic results and also to foster our intuition regarding the behaviour of the test particles. The last part concerns quantum tunnelling of particles through the space-time's hori- zons, specifically the null geodesic method. The main goal of these computations is to obtain horizon temperatures, in which we succeed up to a constant multi- plicative factor. We discuss various pitfalls of the method and stake out a possible approach when applying it to the extreme horizons present in KN(a)dS. 1

The main goal of diploma thesis is to analyse the marketing strategy of Black Light Theatre of Jiri Srnec and to suggest its future improvements. The thesis itself contains six chapters, divided into theoretical and practical parts. First three theoretical chapters are devoted to marketing, marketing mix, situation analysis and marketing and commercial communications and strategies. Following chapters create the practical part of the thesis and contain information about Black Ligh Theatre, analysis of its marketing mix, evaluation of recent marketing and communication strategy and interpretation of field research results. Based on these analyses, the last chapter brings suggestions and recommendations for improvements in future marketing strategy.

Diploma thesis deals with basic physical quantities and laws relating to non-contact temperature measurement and emissivity determination of solids. It describes the design and implementation of the IR (Infra-Red) thermometer often missed with automatic emissivity correction. The first chapter explains the concept of temperature and basic principles of temperature measuring . The second chapter focuses on the history and theory of non-contact temperature measurement. Gradually are explained the concepts related to non-contact temperature measurement and the problem of determining the emissivity of the body.

Šimon Knoška The spherically symmetric spacetimes represent one of the most important classes of solutions in general relativity. Therefore, it is very natural to study them also in the context of modified theories of gravity. We directly continue in the previous works in quadratic gravity, where the generalised solutions with the constant Ricci scalar were found in the form of power series expansion in the conformal coordinates. In this work, we have found an alternative expression of this solution in the Robinson-Trautman-like coordinates analogously in the form of power series expansion around the horizon. Al- though the prescribed recurrent power series solution is more complicated than that in the conformal-to-Kundt coordinates, it posses numerous advantages. Namely, the trans- formation to the Schwarzschild-like coordinates is considerable simple and the physical interpretation of the coordinates is more evident. These properties are demonstrated in the preliminary investigation of the geodesic motion of the test particles near the black hole with analysis of the effect of the so-called Bach parameter. In particular, we have observed that the Bach parameter together with the positive cosmological constant Λ > 0 has a significant impact on the global structure of the spacetime.
