Analysis of temperature profile of 3D printer hot bed and hot end by using CAE
Severa, Tomáš ; Maxa, Jiří (referee) ; Vyroubal, Petr (advisor)
This master‘s thesis deals with 3D printing for non-commercial RepRap 3D printer type and materials used in printing. The outcome of this work is a brief introduction to 3D printing, the theory of heat transfer and analysis of the two most important parts of the printer hot bed and hot end. To analyze and optimize the temperature profile of the hot bed and hot end are used Computer Aided Engineering systems CAD and CAE, SolidWorks and SolidWorks Flow Simulation.

Optimization of location specimens in temperature chamber
Severa, Tomáš ; Pulec, Jiří (referee) ; Šandera, Josef (advisor)
This work is focused on the temperature distribution in thermal chamber CTS. The temperature in the chamber is measured using thermocouples. The measured values are graphically plotted and evaluated. The temperature distribution in the chamber is simulated in ANSYS Workbench. After optimization of the thermal decomposition, is carried out simulations with DPS. It describes the temperature chamber CTS module Omega TC - 08 and software for the thermal simulation ANSYS Workbench.

Testing of the digital levelling instrument DiNi 22 and possibilities of its applications.
SEVERA, Tomáš
The aim of this diploma work was to test, to judge the accuracy and possibilities of applications of the digital level Trimble DiNi 22. It is a precise digital compensatory nivelating appliance, whitch together with a code invare rod answers the requirements for nivelation measuring with 0,7mm/km exactness of both - way nivelation. The exactness of measuring is always influenced by the conditions when the measuring is carried out. Atmospheric conditions infuence the measurement of all geodetic instruments and that is why the major part of this diploma work is dedicated to verifying the influence of atmospheric conditions on the accuracy of the digital level DiNi 22 measuring. For this purpose from September 06 to February 07 were repeatedly measured in different weather conditions separate points of different heights of the nivelation level line Mg 02 České Budějovice - Hluboká n. Vltavou line, which is a part of the nivelation net of IV. line.

Interaktivita v prostředích s prostorovým zobrazováním
SEVERA, Tomáš
This paper deals with the phenomena of spatial visualization and interaction of different ways. Thesis definition of interactivity and individual specifications of different technologies. In this work the terms empirically verified. Practical part is trying to find specifics requirements for interaction in different types of spatial visualization.

The Borders of Fiction
SEVERA, Tomáš
The submitted master's thesis focuses on issues of fiction. First, it pursues the competing definitions of the term itself in order to define it as non-referential sign afterwards. In chapters two to four it presents and comments three traditional approaches to fiction formal, semantic and pragmatic. In chapter five, which is the largest one of the entire work, it addresses in the writings of theorists who largely try to move around the presumed border between fictional and factual narration, usually represented by historiographical works. And finally in chapter six it deals with insights brought to the traditional theories of fiction by two versions of relatively new discipline the simulation theory.

Multi-comparing multimedia live Linux distribution
SEVERA, Tomáš
The goal of this bachelor thesis was to handle a list of current live Linux distributions, and then choose the distributions that are designed to work with multimedia. Then next steps were set of tasks for teaching and working with multimedia and to establish of criteria for evaluating specifically selected live distributions and to choose the best of them. After performing tasks advice which set of applications should be included in the live distribution. Chosen distributions were tested on samples of users, which performed few tasks on selected distributions. All results were statistically evaluated.

Character and its representation in literature
SEVERA, Tomáš
The submitted bachelor thesis focuses on issues of literary character. First, it pursues the individual axis of research of a literary characters ? in their relation to the plot and its superiority or subordination, its way of existence as a textualized human being or as a text function inseparable from a literary work, in the final chapter then, it deals with the comparative study of literary characters and resulting various typologies formed by Edward Morgan Forster, Joseph Ewen and Daniela Hodrová. Before that, the thesis presents concepts of literary character of some significant authors, from Aristotle through Russian formalists, French structuralists and Seymour Chatman to linguistically inspired narrative grammars of Vladimir Jakovlevič Propp and Julien Greimas. Afterwards, the contributions of Tzvetan Todorov, Gérard Genette, Franz Karl Stanzel and Seymour Chatman to the problem of focalization are concerned. In chapter seven the thesis deals with the ways of characterization of characters in literary works or art. Finally, in the last chapter it sees the literary character at background of theory of fictional worlds.
