Short-circuit resistance of the disconnector KBE, 38 kV, 3150 A
Šťastná, Antonie ; Šimek, David (referee) ; Bušov, Bohuslav (advisor)
The bachelor's thesis is focused on the calculations of electrodynamic forces and short-term warming for the disconnector of the company IVEP a.s. within the framework of the issue of short-circuit resistance. The first part contains a theoretical summary of high voltage switching devices, their division and functions. The next part describes the problem of short-circuit currents, and the third part contains an introduction to IVEP devices. In the fourth part, essential information affecting the short-circuit resistance test of the KBE disconnector, 38 kV, 3150 A, is selected and described from the relevant standards related to the topic of the thesis. The main part of the thesis is devoted to calculations of electrodynamic forces affecting on the relevant disconnector and calculation of short-term heating in critical places of the current-carrying path. In the thesis, the achieved results are commented on and possible adjustments are suggested in case of inequality with the standards.

Belt conveyor for brick rubble
Roušavý, Filip ; Pokorný, Přemysl (referee) ; Malášek, Jiří (advisor)
This bachelor's thesis deals with the design of a belt conveyor for transporting brick rubble. The main objective of the thesis is to create an efficient conveyor system that meets the specific requirements of the brick industry. The work includes the classification of belt conveyors, analysis of structural elements, and selection of suitable components. Furthermore, detailed calculations are performed concerning the supporting stations, required motor power, and belt dimensions. The thesis also provides an overview of major belt conveyor manufacturers and describes various types of tensioning and cleaning devices. The result is a design of a belt conveyor that ensures reliable and efficient transportation of brick rubble.

Realization of supercomputer using graphic card
Jasovský, Filip ; Karásek, Jan (referee) ; Mašek, Jan (advisor)
This master´s thesis deals with realization of supercomputer using graphic card with CUDA technology. The theoretical part of this thesis describes the function and the possibility of graphic cards and desktop computers and processes taking place in the proces sof calculations on them. The practical part deals with creation system for calculations on the graphic card using the algorithm of artificial intelligence, more specifically artificial neural networks. Subsequently is the generated program used for data classification of large input data file. Finally the results are compared.

The Calculation Of The Amount Of Material Injury Caused By The Forests In The Areas Of Implementation Of Water Management Structures
Bureš, Petr ; Čermák, Jan (referee) ; Vala,, Vlastimil (referee) ; Alexandr, Pavel (advisor)
Problem situations in damage to forests as a result of construction activities is the total of its quantification, because of not only to damage to the forest and the land intended for the performance of the function of the forest, but also to damage to the water feature of the forest. The emergence of the crop damage and forest grounds occurs at the same time damage to the management. Broken water conditions on the forest grounds, inter alia, that the environmental damage (or one of its components), are also material injury for the owner of the forest, because it directly affect the amount of the additional costs linked to its management in the forest. The existing decree MZe ČR no. 55/1999 Coll. on the method of calculating the amount of loss or damage caused to forests assesses only the injury or damage to the forest and the land intended for the performance of the functions of the forest, but does the forest and its other non-production function as a forest ecosystem. The damage (the material injury) on the water feature of the forest is not the above mentioned decree dealt with. Initially formulated the problem lies in finding the right way of solving how to objectively quantify the financial damage to the forest, inc. damage to the water feature of the forest and thus closer to the actual damage to the exaktnosti forest, resulting in direct connection with the location and the realisation of the buildings.

General purpose analog signal converter
Strážnický, Martin ; Povalač, Aleš (referee) ; Kubíček, Michal (advisor)
This work deals with the design of a galvanically isolated converter of continuous analog signals and the design of a galvanically separated converter of digital TTL signals to HTL signals. The device is complemented by a STM32 microprocessor, which ensures the connection of analog input and output. The result of the work is the circuit structure of individual units, the results of simulations of important units, complete data for the production of device and measured values of individual units.

Signal processing using parallel mathematical operations
Polášek, Jaromír ; Ležák, Petr (referee) ; Mžourek, Zdeněk (advisor)
This Bachelor thesis deals with the acceleration of function calculations, using parallel computing mediated by NVDIA graphics cards via CUDA technology. The theoretical part describes the general principles of parallel computing and the basic characteristics and parameters of graphics cards NVDIA. The theoretical part also deals with basic principles of CUDA technology. End of the theoretical part focuses on FFTW and cuFFT libraries. The practical part deals with the comparison of the performance between GPU and CPU functions filter2D and Canny and practical possibilities of accelerating fast convolution calculation. The practical part also describes sample code that was used to compare the performance between GPU and CPU. The results of this program are then plotted and evaluated.

Estimation of Comercial Property
KLIMENDOVÁ, Lucie
This bachelor thesis is focused on methods and principles of property estimation. These methods and principles are discussed. The paper also provides an explanation of their key parameters and working principles. The thesis also deals with the determination of the value which depends on several factors, like the disposition and age of the property, orientation of the windows, and its location. We face many situations when it is necessary to estimate a property. The most frequent reason for it is applying for a loan. Other situations requesting a property estimate is in case of divorce, sale of the property, or for tax purposes. Further the includes a detailed description of estimation of the particular commercial property in the region of South Bohemia. Finally an evaluation of obtained figures is provided and commented on.
