Optical spectrometer designing
Dohnal, Marek ; Křivák, Petr (referee) ; Hudcová, Lucie (advisor)
This project focuses the problems of projection and design of optical instruments being instrumental to determination of elements in various material compounds. There are described here the structures of fundamental optical instruments and their possible variants, one of which has been chosen and further entered into details. The work specifically refers to an optical spectrometer, which by its nature, ranges the bands both of visible and near-infrared radiation. The work presents basic principles of particular parts, which the existent instrument can consist of, the advantages and disadvantages brought by the single parts. For specifically proposed configuration, intentionally set in such a way it uses state-of-the art measurement methods obtaining the best possible measurement results, the work analyzes in details the method of operation and solves numerically the theoretical assumptions for correct operation of the spectrometer. A constituent of the project is an experimental measurement testifying, with certain errors, to the theoretical solutions. The measurement errors that could result from chosen arrangement and chosen measurement method are numerically expressed in a separate sub-chapter. Further various calibration methods are mentioned, based on which the calibration method used during the experimental measurement was selected. The last part of project is focused on circumferential design of the optical spectrometer, where series of suitable circumferential elements was scrutinized. For basic elements there are presented their parameters and possible troubles related to the implementation. Furthermore the realisation of project was carried out and the spectrometer was assembled with the parts available in laboratory. The results were elaborated with a computer programme created specially for this application and then compared to a professional spectrometer.
The Evolution of Space Telescopes
Bátorová, Silvia ; Sučková, Magda (referee) ; Froehling, Kenneth (advisor)
Tato bakalářská práce se zaměřuje na popis historie dalekohledu, počínaje refrakčními a reflexními verzemi optického dalekohledu a pokračuje stručným nástinem historie radioteleskopu a vesmírných dalekohledů obecně. Poté jsou specifikovány základní vlastnosti kosmických dalekohledů a jejich pozitivní a negativní vlastnosti jsou porovnány. Na závěr jsou popsány tři nejdůležitější vesmírné dalekohledy a jejich přínosy pro vědu jsou objasněny.

Czech mobile providers market through the eyes of Ronald Coase
Benešová, Tereza ; Šíma, Josef (advisor) ; Munzi, Tomáš (referee)
The diploma work is focused on situation and function of Czech mobile providers market. The theoretical background is based on Ronald Coase's findings. The functionality of theoretical hypothesis is verified and further discussed on the basis of foreign telecommunication markets. Different real economics provide valuable experience concerning identification of possible assets and problems. The acquired information is consequently used for analysis of Czech mobile market. Next to the evaluation of the current situation the focus is given to the planned auction of frequencies. Conditions of this auction are described and the potential influence to future Czech mobile providers market is monitored.
