Graph immersions are a natural counterpart to the widely studied concepts of graph minors and topological graph minors, and yet their theory is much less developed. In the present work we search for sufficient conditions for the existence of the immersions and the properties of the graphs avoiding an immersion of a fixed graph. We prove that large tree-with of 4-edge-connected graph implies the existence of immersion of any 4-regular graph on small number of vertices and that large maximum degree of 3-edge-connected graph implies existence of immersion of any 3-regular graph on small number of vertices.

Immersion is a notion of graph inclusion related to the notion of graph minors. While the structural theory of graph minors is extensive, there are still numerous open problems in the structural theory of graph immersions. Kuratowski's theorem claims that the class of graphs that do not contain a subdivision of the graphs K3,3 and K5 is exactly the class of planar graphs. The main goal of this thesis is to describe the structure of the graphs that do not contain an immersion of K3,3. Such graphs can be separated by small edge cuts into small graphs or planar 3-regular graphs. 1

anglicky The aim of the diploma thesis Character of A Journalist in the Danish Series Borgen is to analyze the role and development of the journalist's character in terms of his professional life. At the same time, the aim is to create a representative typology of situations the journalist often gets into. The thesis deals with myths and stereotypes that surround the journalist profession and finds out how are these stereotypes reflected in the audiovisual work. The basis of the analysis and narrative approach is book Narrative as Virtual Reality: Immersion and Interactivity in Literature and Electronic Media by Marie-Laure Ryan. It takes a narrative as a mental image or construct, which consists of a world inhabited by beings who, by their actions, change the world. To create a situation typology the thesis works with set of diagrams. The diagrams visualise relationships and events between the characters. These diagrams are created by a visualisation program that makes it easy to understand the relationships between individual subjects, highlights the repeating situations and the characters at the heart of the action. It also allows more effective analysis through the overal view of the series and their systematic and complete description.

This work focuses on the experience of the first-time user in virtual reality. It explores the psychological and pedagogical aspect of this experience and learning in virtual reality. The theoretical part explains immersion, presence, suspense of disbelief and cognitive presence in order to better explain the users' experience. The process of experiencing VR is compared with a more traditional experiential pedagogy and with its two models. The empirical part is based on data from observations and in-depth semi-structural interviews. 3 years worth of practice by working in the field of research, the VR Dimension gaming centre, is also included in the interpretation of results. The thesis explores the feelings of participants, the perceived depth of their immersion and what might break it in different situations; and their experience in different games, where they felt discomfort, fear or excitement and awe. It also tries to detect the problems that a teacher might encounter when using this technology for educative purposes and offers the solutions based on literature or the researcher's own experience of using this technology. This thesis is meant for anyone who wishes to teach others using VR or for anyone interested in some of the obstruction that may arise.

This diploma thesis deals with the fantasy saga A Song of Ice and Fire written by American author G. R. R. Martin and the analysis of its fictional world. It explores saga's genre classification and focuses on elements that depart from its genre and which enrich it. Through the narratological analysis of the work, it focuses on the main principles of the construction of the fictional world and its specific characteristics. The basic theoretical framework for the analysis of the saga consists of contemporary fictional worlds that are not called fictional in the sense that they would form a fictional narrative but create a new narrative universe. It is designed to help construct further sequels or narrative turns. The diploma thesis also refers to the phenomenon of transmediality, thanks to which the narrative universe continues to expand and the fictional world becomes more realistic.
