Borders and their delineating in medieval Central Europe
Marková, Markéta ; Bláhová, Marie (advisor) ; Žemlička, Josef (referee) ; Lukačka, Ján (referee)
This doctoral thesis deals with the border as a geographical phenomenon in medieval Central Europe. It seeks to answer questions about what is a border, why and how it was created and how its understanding has developed. It deals with ways of delineating an area, boundary signs and rituals. It also explores the course and the concept of borders especially in Central Europe in the Middle Ages but also takes into account the situation of the both earlier and younger periods. It pays attention to the land border of Bohemia and Moravia but also to the borders within the Czech Lands in comparison with similar examples from Central Europe. The work is based on an evaluation of written and material sources concerning the border and combines methods and practices of multiple disciplines: it is based on the results of studies in archaeology, legal history, settlement history, historical geography, general history and auxiliary historical sciences.

Boundaries of the labyrinth. Literary Space in the Italian Postmodern Novels
Čaplyginová, Olga ; Flemrová, Alice (advisor) ; Pelán, Jiří (referee) ; Pechar, Jiří (referee)
The Phd thesis titled Boundaries of the labyrinth and subtitled Literary space in the Italian postmodern novels strives for specification and closer definition of the genre of post-modern novel through the analysis of literary space. Formally, the thesis is divided into three parts. The first part aims to provide a theoretical introduction into the problems of three areas related to the given topic, namely the definition of postmodernity and postmodernism, the genre of the novel itself and last but not least the study of space in literature. The content of the second part is the actual literary and scientific analysis of the selected novels (Città invisibili and Se una notte d'inverno un viaggiatore by Italo Calvino, Notturno indiano by Antonio Tabucchi, Comici spaventati guerrieri by Stefano Benni and Oceano mare and City by Alessandro Baricco) which follows three basic and most frequent spacial topoi occurring in these novels, namely the topos of the city, the house-hotel and the road. The third and final section sums up the observed aspects and characteristics and strives to use them as a basis for determining a certain and generalizing spacial and temporal principle which would facilitate at least a partial characterization of the postmodern novel as an independent genre.

Mushrooms and Slag Heaps: Symbolic Processes and Practices of Group Boundaries Defining in Kukolice
Hrčková, Jana ; Grygar, Jakub (advisor) ; Frantová, Veronika (referee)
Presented paper is concerned with the issue of symbolic processes and practices used for creation of group boundaries of Kukolice community. The village inhabitants use various images and narratives in order to enact the boundaries in relation to the neighbouring Polish group. The main objective of the work is to analyze and understand the aforementioned practices. The paper uses theoretical background based on Cohen's Symbolic Construction of Community, Said's Orientalism and Elias's foreword to the Established and the Outsiders to interpret and analyze the empirical data. The research was carried out in a village inhabited by 390 people, located on the border with Poland in Frydlant area. Unstructured interviews, participant observations and analyses of media and official documents were mostly used during the research. Over the course of the analysis, Poles seem to merge with the images of mine and power plant, dirt, poverty and lesser degree of civilization that are all ascribed to the Polish territory behind the border, following Taussig's concept of mimetic faculty.

Calculation and optimization of synchronous servomotor reluctance torque.
Kroupa, Martin ; Hájek, Vítězslav (referee) ; Ondrůšek, Čestmír (advisor)
This work is mainly focused on construction and design simulation of synchronous servomotor. This motor is built by 30 permanent magnets which are attached to rotor and solved in Ansoft Maxwell 14 software. The main purpose was to calculate reluctance torque, which is significant during the motor operational mode and its optimization. Ansoft Maxwell 14 can analyze in 2D mode as well as in 3D mode, for analysis it uses method of finite elements. Subjects can be analyzed in static conditions, or in any way of transient movement. Optimization in 2D, where we will change the shape in the area of air gap, will only be used as revision that the reluctance torque is bounded with this factor. The main simulations were supposed to be done in 3D model, where the role of rotation should have been taken in account to the final result. These simulations were replaced by alternative calculation. On behalf of achieved results, the optional rotation is stated in the end of my work.

Why Deal With Modern Logistic and Production Premises?
Štěpánek, Martin
Logistic boom in Czech republic brought 3.61 milion square meters of modern storage space. They are facilities for the functioning of our contemporary global society. They are also a burden on the landscape, which we are trying to protect. How to deal with this paradox? It concerns us, architects and urban planners, the issue of logistics and industrial areas, which quickly surrounded our cities?

Light (Magic of Light)
Horák, Ondřej ; Hayek, Pavel (referee) ; Artamonov, Vasil (advisor)
The present work deals in one level with the issue of work and laboriousness in the arts and in the second plane perception of reality and its illusion. Here, briefly explains the function of the visual system, leading to the formation of the image, perception of light phenomena and to create visual illusions (ie. Phenomena, when our perception completely does not match with reality), which served as the basis for dealing with the formal aspects of the work.

Simulation of toroid coils in Ansoft Maxwell 3D
Daněk, Michal ; Pfeifer, Václav (referee) ; Hanák, Pavel (advisor)
The master thesis is focused on the simulation of the toroid coils in Ansoft Maxwell 3D software, which uses finite element method for electromagnetic field simulation. Firstly the process creation of the geometric model toroid coil with seventy-five threaded is presented. It is necessary to debug this model and prepare it for the mesh generation. Physical properties are assign to this model and it gives rise to the physical model. We will set boundaries, excitation current, core material, winding material and the parameters for the mesh generations. New material Kashke K4000 will be created in the materials library and subsequently we will define its BH curve on the basis of datasheet. Analysis is made in two modes. Direct currents (7,5A; 10A; 15A; 20A; 25A) and (non)linear materials are used in magnetostatic solution. Toroid coil is excited by current pulse in transient solution. In Ansoft Maxwell Circuit editor a source which generates current pulse will be created. This excitation will be assigned to the toroid coil as an extern source through a terminal. Core material is linear in the case of transient analysis, because Ansoft Maxwell 3D doesn´t allow to use nonlinear material in this solution. Settings are different in transient and in magnetostatic analysis. End time and time step are entered to solve this task in transient analysis. Time points are entered too. Flux density and electromagnetic field strength are calculated in these time points and later it will be possible to view the results. Calculated fields are shown as the pictures in this thesis. The procedure how to use a field calculator in the postprocessing is given as well. The achievements are summarized in the conclusion.

Grain boundaries in Ni3Ga as paths of rapid diffusion
Čermák, Jiří ; Růžičková, Jana ; Konecny, M. ; Ipser, H.
Grain boundary diffusivity P (P is a triple product of diffusion coefficient in grain boundary D, grain boundary width .delta. and segregation coefficient s) of nickel was measured by serial sectioning and residual activity methods in temperature interval 973-1373 K. Measurements are compared with our previous results on Ni grain boundary diffusivity in Ni3Al. It was obtained that the values of P for nickel in Ni3Ga are slightly higher than those for nickel in Ni3Al. The observed relation between Ps was interpreted by different affinity of diffusing Ni to different components X in the two Ni3X alloys.
