The comparison of classic AlFe line with ACCC technologies
Hrachiar, Róbert ; Jelínek, Ing Milan (referee) ; Orságová, Jaroslava (advisor)
The diploma thesis deals with the comparison of the conduction with the classic "AlFe" ropes (ACSR technology - aluminium conductor steel reinforced) and the line with the ACCC technology (aluminum core composite core). The first part describes the development of the transmission and distribution network in the Czech Republic. Subsequently types of conductors are described, its construction and main characteristics. The theoretical part also consists of theoretical knowledge about compared types of conductors and knowledge from the field of external lines. During the creation of the theoretical part of the thesis, we gained experience in the advanced functions of Excel, which are later used in practical part. The practical part of the thesis consists of creation of the calculation program itself, instructions and calculation methodology. Included is also an example of use of the program that compars two types of conductors of the same diameter, the same transmitted current and the same weight per unit length.

Solar Applications with Concentrator Elements
Hrachiar, Róbert ; Radil, Lukáš (referee) ; Baxant, Petr (advisor)
The subject of this bachelor thesis are solar applications with concentrator elements. In the thesis are described theoretical knowledges of various types of concetrator systems, development history, separation, system description, economy and usage of concentrator systems. Basic information about solar irradiation, which is useful for concentrator systems, it's separation and the possibilities of using in our enviroment are also described in the thesis. In practical part is designed model of solar concentrator, a description of realization and following measurements on constructed model.
