Porovnání různých metod izolace genomové DNA hmyzu
Novák, Vojtěch
This thesis deals with description and verification of different methods of DNA isolation from insect tissue of order Lepidoptera -- butterflies with an emphasis on family Sphingidae -- hawk moths and subsequent amplification of COI gene by PCR method. All tested methods were compared and evaluated in terms of efficiency, yield and purity of the DNA isolation, duration and financial costs. We selected to establish a methodology which is sufficient for obtaining COI gene sequences using genetic analyzer, its application in the system BoldSystems and subsequent determination of the sample. This is important in effort to map the species diversity.

MV netwok design for 75 new houses in Damborice
Makuta, Peter ; Novák, Vojtěch (referee) ; Ptáček, Michal (advisor)
Content of this thesis is medium voltage network design for seventy five houses in Damborice. At the beginning author discuss about history of transmission network and distribution network. Next topic is about steady state of network. In theoretic part are different solving methods of linear and non-linear simultaneous equations discussed. Author describes four methods – method of node voltages, elimination of balance node, Gauss-Seidel and Newton method. The electric properties of both the overhead transmission lines and cable lines and their variety are part of this work too. There is purpose, forms and parameters of transformers described. Simplicity of author’s design should reduce the usage of many electrical elements visible to residents.

Design of the distribution network branch for new family and apartment houses in Újezd u Brna
Frechová, Lucie ; Novák, Vojtěch (referee) ; Ptáček, Michal (advisor)
The work mentions the concept of present electricity networks in the Czech Republic and based on voltage levels it also describes distribution networks in more detail. Furthermore it brings the analysis of legislative conditions and technical aspects, under the rules of the distribution network operation, for new customers who require new connection to electricity network. Because of the steady-state network evaluation represents very important issue of the power system calculations, therefore it is explained in theoretical part of this work. Nowadays, Gauss-Seidel method and Newton iterative method are generally used for the steady-state analysis. Mentioned ones are also described and compared together in theoretical part. Furthermore methods are applied in practical part which solves specific configuration of the network in a given area. Moreover there are the basics of the conductor sizing in terms of the warming, both during normal operation and during a short circuit. However, it is necessary to respect other aspects of the conductor sizing, therefore issues of mechanical and electrical strength, the voltage drop and the sizing economy are also shown. There is also the characteristic of proposed and the description of the individual components which are used for the network i.e. transformation station, HV and LV switchgear, transformer, HV and LV cabling. It also concludes the characteristics of the design opportunity with their power and economical comparison.

A Price Map of Vacation Property Sales in the Eagle Mountains and its Use
Novák, Vojtěch ; Jachan, Tomáš (referee) ; Kosová, Jaroslava (advisor)
The master's thesis is divided into two parts. The term „property“ and also terms dealing with segment of the vacation properties are defined in the theoretical part. Then there are defined different types of prices and valuation. This part also deals with the fact, that affect the selling price. Price maps and their importace at present are discussed in the last chapter. The practical part deals with procedure of creation of the price map, whose byproduct is creation a form for the estimation of the usual price. The region is defined here, including charakteristics of individual location, followed by a description of the property market in the region and analysis of the data base for creating price maps. The price map in text and graphic vision and the form are output. Estimation of the selling price of the property is generated after filling the form. The applicability of the form is verified by determination of the selling price of farm house in Slatina nad Zdobnicí. This property is also being valued according to price regulation in parallel. The practical part is completed by comparing of both achieved prices.

Proposal of the reconstruction of the distribution network in a specific area
Novák, Vojtěch ; Mrvová, Dana (referee) ; Blažek, Vladimír (advisor)
This diploma thesis is concerned with reconstruction of distribution network in Hruba Vrbka. The diploma thesis is divided in two parts. For better understanding to this issue, the first theoretical part is shortly dedicated to the history of electrical power system, to the several types of distribution network of low voltage and high voltage and their utilization in the area, considering the reliability and the quality of delivery of the electric energy. In this thesis there is mentioned division of distribution grids according to placing of cable lines, according to voltage and according to type of grid connection. Next part of this work is dedicated to the description of overhead lines and cable lines and their characteristics. For the proper concept of the grid we should know some characteristics of the electric line’s proposal: mechanical strength, warming, voltage drop, efficiency, degree of safety and provision of delivery. In the end of the theoretical part there are described methods for calculation of grid’s steady state as a linear task and also non-linear task, elimination of the balancing node, the iterative method, the reduction of external power take-off nodes and the solution of the steady state of the network through the direct current model. The second part of the diploma thesis is concerned with the calculation of the steady state in the village Hruba Vrbka. In this part is also described the KASI program which was used for the calculation of the grid’s steady state. Firstly low voltage grid’s balance in Hruba Vrbka was found out and evaluated and then there were proposed some solutions of the reconstruction for the grid improving. The suggested options of the reconstruction are considered from technical and economical point of view and the best solution is chosen. For this solution there is suggested the protection through program SICHR 9. In the end of this diploma thesis there is checked the load of the high voltage line.
