High Voltage Switchgear Thermal Distribution Analysis
Bílek, Tomáš ; Rudolf, Pavel (referee) ; Hrabovský, Jozef (advisor)
Cílem této práce je analýza teplotního pole vysokonapěťového rozvaděče. Tato analýza je založena na kombinaci experimentálního měření a CFD simulace proudění vzduchu v prostoru rozvaděče. Na základě výsledků pro referenční geometrii jsou předloženy návrhy na úpravu topologie rozvaděče, které mají za cíl snížení teploty kritických komponent rozvaděče během jeho provozu. Druhá část práce je spojena s problematikou oteplení plošných spojů, jakožto hlavních zdrojů tepla v prostoru rozvaděče. Pro popis závislosti oteplení plošného spoje na jeho charakteru byla použita statistická metoda design experimentu. Výsledky z experimentálního měření jsou podpořeny konečně prvkovým modelem kontaktu spoje.

The multistorey office building
Bílek, Tomáš ; Sýkora, Karel (referee) ; Šmak, Milan (advisor)
Design of a new steel structure administrative building in Zlín. Structure is consist of three parts. The part A is designed of three fields in the transverse direction and five fields in the longitudinal direction. This part is two-storey. The part B is designed of two fields in the transverse direction and three fields in the longitudinal direction. This part is six-storey (five-storey). The part C is designed of two fields in the transverse direction and five fields in the longitudinal direction. This part is four-storey (three, two-storey). In both directions in all parts of the building is the distance between the columns in all fields of 6,0 meters. Structural elevation of all floors is 3,5 meters. Shape and dimension design. Fixed, utility, climatic load. The purpose is confrontation of inner forces and dimensioning of main supporting elements in three variations of structure. Comparsion of variations. More detailed static calculation, drawings for the selected variant. Detailed drawings for part of building.

Algorithm for Calculation of Radiation View Factors
Bílek, Tomáš ; Hlavička, Rudolf (referee) ; Čermák, Libor (advisor)
This thesis deals with a calculation of radiation view factors. The thesis includes mathematical model of the problem and its numerical solution. The main aim of the thesis is the creation of an algorithm for calculation of radiation view factors for given 3D geometries and its application for the heat flux analysis. CAD models of geometries, specified by a NASTRAN file format, are used as an input of the algorithm. Matrix of radiation view factors serves then as an output of the algorithm. The algorithm is programmed in MATLAB, but STAR-CCM+ is used for the NASTRAN specification of separate models. The algorithm is also designed for a computation on a computer cluster for cases of intricate geometries with consideration of shading areas.

Project management of information system implementation
Bílek, Tomáš ; Maryška, Miloš (advisor) ; Mezerová, Lubica (referee)
The main theme of this thesis is a project management methodology applied to the imple-mentation of an information system. A nonprofit organization in the state administration of the Czech Republic is implementing a new system supporting processes of inventory gov-ernance and revenue in form of ticket sales. The management procedures and methods are analytically processed and evaluated. The aim of the thesis is to choose the appropriate standard of project management. Use this knowledge to analyze the completed project and subsequently find a recommendation to enhance the effectiveness of the project management in the organization Muzeum v Brun-tále. The theoretical part is focused on the expert knowledge from literature on the selected top-ic. In the thesis there are mentioned internationally recognized project management stand-ards. One of them is selected as an optimal methodology for the practical example. The paper describes project management using PRINCE2, it captures applicable methods and procedures, which are then applied to the selected project. Analytical part introduces organization Muzeum v Bruntále. The organization decided to modernize one of their key information systems last year, specifically the system for reser-vations. The main functionality of the system is printing and management of tickets, e-governance by electronic inventory control. The main part of the paper focuses the process of planning, decision making and implementation of the system itself to analyze the costs and benefits for the company. Achieved findings and recommendations can help the management of the museum to check the completed project or the management can improve the internal corporate meth-odology of project management.
