Determination of Variation Components from Geodetic Micronetwork Adjustment
Váchová, Hana
This paper deals with the design of a procedure to determine the accuracy of a total station. It is based on the surveying of a geodetic micronetwork and subsequent evaluation of the measured data using the created software tool. The calculation works on the principle of least squares adjustment with the application of the Förstner method of estimation of variation components. In addition, the calculation is enriched by the possibility of determining residual errors of the prism constants.

Railway track deformation measurement
Leischner, Ludvík ; Bureš, Jiří (referee) ; Švábenský, Otakar (advisor)
This bachelor thesis is about measuring deformations on railway bridge in Znojmo. The horizontal and vertical changes of railway track on the bridge and newly renovated bridge construction were measured by using two independent methods, namely 3D polar method and kinematic GNSS Stop & Go method. The assessment of the longitudinal shifts depending on atmospheric conditions especially the temperature changes is an essential goal of this work. Another key aim is the determination of precision of both independ-ent measuring methods.

Portfolio Diversification through Investment in Stock Indices
Křižka, Adam ; Ryndová, Jitka (referee) ; Rejnuš, Oldřich (advisor)
The diploma thesis focuses on the design of suitable stock exchange indices for portfolio diversification. The essence and principle of functioning of financial markets and investment funds is presented. According to suitable indicators, stock exchange indices are analyzed and compared with the market. Suitable indices are verified by means of correlation analysis and subsequently recommended to diversify the portfolios of investment funds managed through the investment company.

The Use of Means of Artificial Intelligence for the Decision Making Support on Stock Market
Vaško, Jan ; Kříž, Jiří (referee) ; Dostál, Petr (advisor)
Diploma thesis deals with analyzing the possibility of using artificial intelligence, specifically artificial neural networks and fuzzy logic, on the capital markets as a tool to support decision making in business. The Matlab software is used for this purpose. The work is divided into three parts. The first part deals with theoretical knowledge, brief description of the current situationin is covered in a second part and the theoretical solutions are applied to the system in the third section.

Securities portfolio optimization
Pinkava, Ondřej ; Bartošek, Vladimír (referee) ; Sojka, Zdeněk (advisor)
This dissertation deals with the securities portfolio optimization. After introducing the definitions, I try to explain the particular investment instruments with regard to returns and risks. The following part provides a theory which tells more about different market risks and returns on the final securities portfolio. Concerning these models the effective portfolio has been set up.

Preprocessing of 1D gel electrophoresis image
Svozilová, Veronika ; Škutková, Helena (referee) ; Vítek, Martin (advisor)
The aim of this work is to propose an algorithm in MATLAB, allowing image processing and evaluation of one-dimensional gel electrophoresis. At first describes the detection of samples based on the horizontal segmentation of electrophoresis gel image, followed by detection of the minimum intensity values of the image, a vertical segmentation and determination of the sample boundaries in the image. The final phase involves testing of the method on publicly available images and evaluation of the results.

Optimalization of the die cast process of high-voltage transformers.
Borunský, Tomáš ; Fiala, Alois (referee) ; Maroš, Bohumil (advisor)
This thesis deals with choises of using mathematical statistics when optimising the compression casting process of high-voltage device transformer. There is a theoretical consideration to be found in the introduction which concerns the compression casting itself and all necessary information connected with it. Then there is a key numerical analysis part following. In the first instance there are variability problems of individual casting device discussed and then a regression analysis made to demonstrate and prove a link between the partial discharge and the key parameters of casting process. Finally an “optimal” casting sequence is suggested and alternative attitude problems with the assistance of Design of Experiments (DOE) are discussed.

Quality of The Track Geometry Progress
Nejezchlebová, Jitka ; Kulich, Pavel (referee) ; Svoboda, Richard (advisor)
The bachelor ’s thesis deals with the development of track geometry over time. The theoretical part describes the methodology for measuring and evaluating of track geometry. The practical part deals with the section evaluation on the double-track line Brno Maloměřice - Adamov. The MATLAB system was used for evaluation. For chosen sections, the graphs were regressed to determine the quality development for all parameters. Regressions were also used to determine which parameter deteriorates the fastest over time, in which track the parameters deteriorate faster and whether it can be said that the increase is faster before or after the repair.
