Application of kriging in engineering problems with uncertainties
Tvrzník, Jakub ; Lehký, David (referee) ; Vořechovský, Miroslav (advisor)
The presented bachelor thesis aims at interpolation method called kriging, which is based on regression of values measured in the surroundings. Kriging is based on the idea that interpolated function is one realization of a random field. Using this method we can quantify the estimates of functional values at the surrounding points, including estimation errors at each point. At the same tame, kriging respects the exact measured values and the interpolation passes through them. The practical part demonstrates the application of method to engineering tasks, where the measured values are distributed randomly. In other examples, the measured values are distributed by using a grid.

Proposal measures at upper reaches Svratka River
Klepárníková, Radka ; Smelík, Lukáš (referee) ; Uhmannová, Hana (advisor)
The diploma thesis deals with the proposal of measures on the Svratka stream in the cadastral area Český Herálec and Herálec na Moravě. The aim of the diploma thesis is to propose appropriate flood protection in the Herálec urban area and to elaborate proposals of nature friendly measures outside the municipality’s built up area, which will enable the renewal of the ecological functions of Svratka in the spring area. In the diploma thesis the assessment of the current state of the watercourse in the analyzed locality was caried out and also the assessment of the capacity of the watercourse and the objects on there. Furthermore, the flood levels and its areas were determined. Hydraulic water flow calculations were performed using the 1D and 1D/2D numerical model. For calculation, HEC-RAS 5.0.3 was used. When processing a 1D/2D numerical model, a manual describing the progress of work in the HEC-RAS 5.0.3 program was also created. On the basis of the results from the numerical model, a proposal for flood protection measures in the urban area and nature friendly measures in the extravilan was carried out.

efficiency of the bottom elements on the supercritical flow energy dissipation
Knoflíček, Jakub ; Haluza,, Miloslav (referee) ; Šulc, Jan (advisor)
The thesis is dealing with comparing dissipation of the kinetic energy water flow using various bottom elements based on model research. There is missing information about efficiency of different kinds of bottom elements. This absence does not allow to compare different modification of the bottom of stilling basins. Within experimental research were measured depths in different variants. Based on the results of model tests are evaluated and tabulated sorted variants of the combat efficiency of the kinetic energy water flow. The results will be used for the efficient and economic design of additional alterations of stilling basins.

Strategie učení
FOUROVÁ, Lucie
My diploma thesis deals with using learning strategies when learning the English language. To research the learning strategies of students I will carry out a case study in one particular class of lower level of an eight ? year grammar school. The theoretical part is focused on the evaluation of the current knowledge and description and characterization of particular learning strategies. It stresses the importance of learning strategies in the context of the contemporary educational system. I also refer to the role of teachers and students with regard to using learning strategies. The practical part of the diploma thesis deals with the determination of measures in which the students of one particular class use learning strategies. To find out about learning strategies of the students I will use an existing questionnaire called Strategy Inventory for Language Learning (SILL) for my case study. On the basis of the gained data I will determine the measure of using learning strategies of particular students and the whole group. After that I will suggest a set of exercises which support mainly the development and use of the direct learning strategies.
