Influence of Wind Farm Integration to Power System
Pospíšil, Petr ; Belatka, Martin (referee) ; Malý, Jiří (advisor)
This bachelor’s thesis is divided into four main parts. The first point includes a characterization of the origin of wind, a principle and a division of the wind – mill motors and a characterization of a wind power plant. The second part analyses effects which the wind power plans have on the power system and also analyses grid problems with large amount of installed wind – mill motors. In the other point national grid codes are analysed (such as Germany, Denmark, Ireland). On the bases of these analyses the suggestions of the modifications of the Czech distribution grid code are summarized.

Distribution Network Development and Configuration
Pospíšil, Petr ; Beneš, Jan (referee) ; Topolánek, David (advisor)
The theme of this master‘s thesis is distribution network development and configuration in the part of Brno – Trnitá. There is expected to be investments there in the next few years. The thesis consists of two parts. For better understanding of this problem, the first theoretical part concerns with the description of electrical network (subdivision in accordance with voltage levels, conductor types, network types and other electrical network parts), solution of grid’s steady state (as a linear task and also non-linear task, elimination of the balancing node, the iterative method) and Brno distribution network characteristics. The second part concerns with distribution network development and configuration depending on anticipated load development in Trnitá. The result is proposal for transformer station construction Opuštěná fitted with three transformers of nominal output SN = 40 MVA and network configuration change required both for providing new consumption supply as well as sustaining current one.

3D triangulation technique for object reconstruction
Pospíšil, Petr ; Richter, Miloslav (referee) ; Janáková, Ilona (advisor)
My paper work deals with the 3D active triangular method of building reconstruction. First, there was a measuring triangular system created. Then the way of its automatic calibration was proposed and consequently also performed. Also algorithms for the automatic detection of the sample projected were proposed. Algoriths were presented with several sample buildings. The result of these algorithms are 3D models of individual buildings. In the end achieved results nd restrictions of the system proposed were assessed.

Optimization of network position prediction
Pospíšil, Petr ; Pfeifer, Václav (referee) ; Burget, Radim (advisor)
This work is about position prediction in network, it is focused to find Landmark closest to the Host in the network (with lowest distance vector). The algorithm is based on GNP system. In terms of GNP system simulation was selected method for mathematical part of position prediction. The method was Simplex Downhill. The designed algorithm was implemented in Java. In the first step chose Host continent by meassuring the distance vector. In next step is selected nearest part in the continent. In conclusion estimate Host its position and then closest Landmark. Results from this work is important for designing TTP protocol. The verdict is that the GNP can be used for TTP, but Landmarks must be located in uniform density.

Price analysis of building with changes of construction materials
Pospíšil, Petr ; Vovesný, Jan (referee) ; Aigel, Petr (advisor)
The following bachelor thesis concentrates on the analysis of construction expenditures dutiny the process of introducing material and construction changes. We have selected four variant of the given construction systems supplied by four different providers. This has been conducted under the following condition: all the four variants has a common heat transfer coefficient. U= 0,14 [W/m2K]. Among the selected systems we have included Heluz, Velox, Porotherm and Ytong. Under Heluz system we have chosen Heluz Family, ground surface, thickness 500 mm. This system does not involved contact insulation. As for Porotherm, we have decided for ceramic breeze blocks Porotherm 30, thickness 300 mm, to follow the obligatory common heat transfer coefficient, therefore we have also suggested contact insulation as of 220 mm. The third system, Velox permanent boarding, VELOX WS EPS PLUS thickness 420 [mm]. This system fully complies with the heat transfer coefficient requirements. Finally, we have used Ytong breeze blocks 300 mm in thickness. For this solution there also arose a need to design the contact insulation to follow the heat transfer coefficient requirements. For ech project variant we have designed project documuntation as a the basis for further budget item calculations pertinent to each single project variant. The item budget calculation was made using KROS PLUS programme. The overall budget prices and variables in each project variant have been comapred with each other, the data processed into several graphs accordingly. Among the variables we have included ground works, founding, vertical and complete constructions, horizontal constructions, surfaře finishing works, flooring and filling works, thermal insulations. Furthermore, purchasing prices for each invividual type of material, based on provider prices list, have been compared with prices as given by KROS PLUS programme.

Easy Money Policy of the Federal Reserve System in the 1990s
Pospíšil, Petr ; Johnson, Zdenka (advisor) ; Tajovský, Ladislav (referee)
This thesis focuses on monetary policy of the Federal Reserve System in United States in the 1990s. The emphasis during the analysis is put on recession of 1990-1991 and occasions which lead to market speculation, followed by US economy stagnation after its burst. I deeply analyzed the issue and contradictory opinions of renowned economists I conclude that American central bank's decisions during 1995-2000 contributed to the increase of stock market speculation. Nevertheless, these decisions were made in consistency with then crises of domestic and global economy with the aim of ensuring price stability and economic growth. Hence, my conclusion is that monetary policy of American central bank did not exactly cause the crisis, it was mainly investor's exuberance due to wave of new technologies emerging in the 1990s.

Shifts in Perception of Melchizedeks Figure in the Old Testament, Intertestamental Literature and the New Testament
POSPÍŠIL, Petr
This work concerns the shifts in the perception of the figure of Melchizedek in the Old Testament, Intertestamental sources and the New Testament. It explicates three central biblical texts which are speaking about Melchizedek. These texts are: the book of Genesis 14, Psalm 110 and the Epistle to the Hebrews. The work also aims to notice perceiving Melchizedek{\crq}s figure in non-biblical sources, like Qumran texts, Targums, apocryphs or the testimonies of church fathers. The findings coming from these sources are compared together in the conclusion of the work. Each of traditions is different, so we can not make unambiguous conclusion about figure of Melchizedek. Some non-biblical Melchizedekian traditions still continue, some others have disappeared entirely.
