Primary testing of the protection relays
Macek, Vratislav ; Topolánek, David (referee) ; Toman, Petr (advisor)
The main subject of this bachelor’s thesis is the creation of laboratory task on the issue of primary injection testing of the protection relays. The thesis is made up of two parts: theoretical and practical. In theoretical part there are information concerning the issue of protecting. One of them the meaning and relay function, requirements applicable on them, failure states, which may arise on the device operation, description of instrument transformers and methods of testing relays. In practical part is created laboratory task on the issue of primary injection testing of overcurrent relay, of which will demonstrate the influence of load current transformer to its function. In task are used Overcurrent and Earth-fault protection REJ 525A and measuring instrument Omicron CPC 100.

Source for heat production in the Czech Republic
Macek, Robin ; Kracík, Petr (referee) ; Baláš, Marek (advisor)
This bachelor’s thesis deals with sources for heat production in the Czech Republic. The first part is a research part and is about used heating technology in our country. The second part is again research part and describes individually in more detail parts of the heat sources, as boils, turbines, heat exchangers a heat distribution. The next chapter compares advantages and disadvantages of central heat supply and local source of heat, first theoretically and then practically. The last part balances production of the heat and electricity from the point of view of the fuel used and the amount of production over the past 15 years.

Mobile applications development for remote control of instrumentation
Macek, Michal ; Křivík, Petr (referee) ; Frk, Martin (advisor)
The presented work describes the growing trend of using mobile devices to control laboratory instruments and displaying of measured data. The main objective is the application development for mobile devices, which will allow to remotely control and measure with laboratory instruments. The practical part is focused to programming mobile application which will be able by using the local network to connect multiple laboratory instruments, setting them for different types of measurements and then display measured data.

Partial discharge
Macek, Vratislav ; Krbal, Michal (referee) ; Toman, Petr (advisor)
The main subject of this diploma’s thesis is the creation of laboratory task on the partial discharge. The thesis is made up of two parts: theoretical and practical. In the theoretical part there are information about partial discharge. One of them is classification partial discharge by type, effects of partial discharge in insulation systems, parameters to assess the quality of electrical insulation of power systems and measurement techniques. Further part is user’s manual for measurement instrument. In practical part is created laboratory task on problematic of the partial discharge measurement. It is demonstrative measure of partial discharge with the aim of understanding problematic of partial discharge, calibration and noise.

Smečno, and Art of the Late Gothic Era in the Service of the Martinitz Family.
Havránek, Pavel Jaroslav ; Ottová, Michaela (advisor) ; Macek, Petr (referee)
(EN) The Bachelor Thesis will map the fond of the Late Gothic Era made up of the works connected to the Martinitz's residential city of Smečno. The fond includes: the castle chaple of St. Anne and its furniture, the Ledce Altarpiece, the Smečno Madonna etc. The aim is to base the core of the thesis on archival research and the stylistic analysis of the artworks. Space will be further given to a survey of the artworks' further fates before and after the year 1918, in which the influence of the Martinitz family, or, since 1792, the Clam-Martinitz family, was interrupted in Bohemia and therefore also at Smečno. Due to historical events some of the artworks from Smečno found their way to other places and institutions, like the National Museum or the National Galery in Prague, by which their coonnection to Smečno was often severed. I will try to connect the artworks with specific locations at Smečno, the Church of the Holy Trinity and the castle chapel of St. Anne, and with the commissioning activities of the Martinitz family. Keywords: Smečno, Late Gothic era, Sculpture, Wood carving, the Martinitz, the Clam- Martinitz, Master of Doksany Altarpiece.

Baba housing estate - history and present
Varyšová, Eliška ; Biegel, Richard (advisor) ; Macek, Petr (referee)
Baba housing estate - history and present Eliška Varyšová Abstract (english version) Abstract The work Baba housing estate - history and present deals with a phenomenon of functionalist exhibition colony in Prague district Dejvice. The history and European context were compiled in two monography publications, in that reason autor tries to research an afterwar progression and especially a present state of individual houses from the view of monument preservation. The work is divided to three parts. The first part focuses on European context and formation of housing estate, the circumstances of construction and results. The second chapter describes destinies of houses and place from 1948 to the present and issue of the preservation of the colony. The third part is a catalog of 10 houses that represent different approach to maintenance and preservation of housing estate. In the conclusion autor summarizes knowledge and tries to answer the question how to preserve a historic identity of place and an autenticity of houses and colony.

Species diversity of vascular plants in alpine vegetation of the Western Carpathian mountains on different spatial scales and its connection to soil pH
Anderlová, Nikoleta ; Sklenář, Petr (advisor) ; Macek, Martin (referee)
Alpine regions are hotspots of species diversity and are therefore at focal center of scientific interest. The research aiming to understand the influences and patterns that shape this unique environment, is complicated by mulitple metodological issues stemming from unclear definitions of used terms as well as the existence of various methodological approaches and their constrains/limitations. The breadth of the topic of species diversity, which can be viewed from multitude of perspectives, is also adding to complications. This work summarizes the most important information in available literature and addresses important correlations and trends in environmental variables and species diversity of alpine meadows in the areas of Malá Fatra, Nízke Tatry, Roháče, and Belianske Tatry. At the center of attention is the widely accepted theory of higher species richness in areas with basic, calcareous substrates compared to areas with acidic, silicate substrates in Europe. To confirm this theory at different spatial scales in alpine environment, hierarchical sampling was chosen. A total of 96 samples containing data on the presence/absence of plants and relevant environmental factors, including pH measurements, were obtained. The structure of these data was visualized using ordination techniques such as PCA...
