Solar cell non-destructive analysis
Černý, Michal ; Škarvada, Pavel (referee) ; Macků, Robert (advisor)
This thesis briefly analyse contemporary situation of photovoltaic systems and their actual developemenet. It shows a typical properties of most produced up-to-date types. Decision point of this thesis consist in nondestructive analyse of monocristalic unijunction solar cells. It describes two main diagnostic aproaches. First – through the use of measuring of VA characteristics, second – through the use of measuring noise characteristics. With selected samples are performed experimental measurements and estabilished basic parameters. In case of drone analysis considerably attention is devoted to experimental equipment for automatized measuring of spectral power density. This experimental equipment is consequently used for measuring some samples where we can observe microplazmatic noise.

Optimization and parameter measurement of PON network FTTX
Černý, Michal ; Křepelka, Václav (referee) ; Filka, Miloslav (advisor)
Práce rozebírá současný vývoj na poli pasivních optických sítí a jednotlivé generace přenosových standardů. Podrobněji se zabývá parametry ODN, metodami jejich měření a volbou potřebných měření v praxi. Hlavní část práce je zaměřena na měření pasivního WDM prvku, kde je provedena analýza vstupů a výstupů, měření vložného útlumu a přelechů podle ORL na provozních vlnových délkách.

Price Comparison of an Apartment Building in the Bučovice Cadastral Area According to the Valid Valuation Regulations
Černý, Michal ; Hlavinková, Vítězslava (referee) ; Karabec, Jiří (advisor)
Diploma thesis introduces two different options for property valuation. With an emphasis on the different ownership of the apartment building. In the first case, the building seen as a whole and used the combination of yield and cost method of valuation. In the second case, a building is divided into individual residential units and valued method of comparison. Both methods are conducted in accordance with Decree No. 3 / 2008 digest Implement certain provisions of Act No. 151/1997 digest., Valuation of property and amending certain laws, as amended (Decree valuation), as follows of the changes made by Decree No. 456/2008 digest. and No. 460/2009 digest. In conclusion, the following derived values were compared and evaluated.
