Aim of this diploma thesis was to study the protective effect of vegetation from the point of view of the two most common types of erosion in the Czech Republic, water and wind. The theoretical part of the thesis is focused on the degradation processes occurring in the soil, the threat of agricultural land by water and wind erosion, with a focus on wind erosion. Based on the analysis of data from the selected stations, changes in phenological occurrence of selected crops, sugar beet and corn were examined. The issue of changing climate and its influence on the course of wind erosion was characterized. On the other hand, soil erosion control was described based on the rules of GAEC (Good Agricultural and Environmental Conditions) where critical periods of growth of field crops are limited. In the practical part, the Mann-Kendall test was performed; based on this test changes in the onset of phenological phases and agrotechnical operations were found. Furthermore, the areas which are most endangered by wind erosion (Tvrdonice, district Břeclav) were defined, where based on the identification of critical periods field measurements were performed with deflameter and monitoring of erosion occurrence. Subsequently, qualitative parameters of soil particles were found on the basis of the spectral analysis of the deflametric record in the period of dangerous erosion episodes.

The master thesis deals with the problematics of machine guard. The first part of the thesis is focused on the analysis of machine guards, legislative safety requirements and noise issues. The second part of the thesis describes design and construction of the machine guard in case of the vertical turning centre, TOSHULIN - POWERTURN 2000, including the calculation of noise reduction.

Lenka Soukupová, Zvětrávání arsenopyritu v lesních půdách v acidifikovaném prostředí SUMMARY The weathering of arsenopyrite (FeAsS) has been studied at the experimental site Načetín in the Ore Mountains, Czech Republic. There were chosen three areas with different vegetation (beech, spruce a unforested areas) at this site. The arsenopyrite samples were placed in all soil horizons (litter, horizons A, B and C for forest areas; horizons A, B and C for unforested area), where they were exposed to ambient conditions for one year. After one-year weathering, the newly formed secondary minerals were identified and the rate of surface oxidation was determined, both depending on the environment of oxidation. Although physical-chemical parameters and content of main and trace elements of the studied soils varied, the only detected crystalline secondary mineral of arsenic was scorodite (FeAsO4∙2H2O). Nevertheless, this differences affected amount of formed scorodite. The highest concentrations were determined on the surface of the arsenopyrite grains that oxidized in the beech stand, conversely the lowest concentrations were determined on the arsenopyrite grains from the unforested area.

This thesis deals with the design and testing of the acoustic enclosure for the Inova hydraulic actuator. The purpose of this enclosure is the acoustic insulation of the actuator and its parts, to achieve better acoustic conditions when performing acoustic diagnostics on this device. The first part deals with the theoretical basis of acoustic enclosures, the possibilities of modelling of acoustic problems and market research in materials usable for enclosure construction. The second part deals with the analysis of actuator noise and the localization of noise sources in the laboratory. Subsequently, the choice of material and concepts of the acoustic enclosure was made. Then, the final design solution was selected. The final design solution was subjected to acoustic simulations to predict insertion loss and determine the dimensions of the enclosure. The manufactured enclosure was tested in a semi-anechoic chamber and finally on the Inova actuator. Finally, the measurement results and simulation results are compared with each other.

This master's thesis is focused on the modeling and tracks of thin-walled components. Used softwares are CATIA V5R20 from Dassault Systemes for Experimental Component Modeling and PowerMILL 2018 from Autodesk for Draw and NC Programming. The production efficiency between the precision casting and the workpiece of the cube blank based on the material utilization factor and machining time is compared in this work.

The thesis deals with measurements of the atherosclerothic carotid plaques mechanical properties with wiew towards the improvements of their constitutive models and then towards the impact of application of those constitutive models in fibrous cap. The introductory part provides a brief summary of medical knowledge needed to understand atheroma formation and the risks involved. Next, there's a survey of plaque mechanical testing methods and the obtained results on tissue properties. The previously used constitutive models of atherosclerothic tissues are listed as well. Main body of the thesis describes the preparation of testing samples from obtained atheroma, methodology and course of experiments execution and subsequent processing of the experimental data to evaluate the behavior of the atheromatous tissue individual parts. Then the discussion and evaluation of our results and findings is given. Along with the evaluated mechanical properties, experimental data fitted to models are presented with respect to their predictive abilities. The final part is dedvoted to the finite element analysis of an idealized 2D model with emphasis on the effect of necrotic core and fibrous tissue properties on von Mises equivalent stress in the fibrous cap.

The subject of the thesis is a transformation of the anti-nuclear shelter situated in the city center, which no longer fulfils its original function. The main goal of the project is to integrate the shelter to surrounding public spaces. The proposal uses the potential of the suitable location on the edge of the historical center of Brno by inclusion of public facilities with cultural functions that are able to use the uniqueness of the underground space. The aim of the study is to point out this unused building, initiate discussion. My quest is to bring new impulse to the city, to enhance the site with a new feature, make a pleasant urban space to residents of the city and also bring life to the place.

The thesis titled "Cost analysis of engineering structures" presents a comparison of the life cycle costs of linear structures with an asphalt surface against the life cycle cost of linear structures with a concrete surface. The thesis deals with prices, costs, calculations and budgets in its theoretical part. The following chapters present history and current status, road constructions, life cycle of the construction and differences between concrete and asphalt covering. Practical part of the thesis is divided into three parts. In each sub-section, there is a practical example of comparing the costs of the life cycle of linear structure with the asphalt surface against the costs of the life cycle of linear structure with the concrete surface. Everything is expressed in graphs.

Diploma thesis deals with the design of producing the cover drain. The cover serves to catch impurities while draining liquids. The part is made of 1.4301 stainless steel, using 1-mm thick sheet metal. The size of the annual production series is 30,000 units. As an optimal method of production, progressive cutting and shallow drawing were selected in a combined and a one-purpose tool. Technological and design calculations were performed according to which tools were designed. The LENP 100 press was selected considering the total required pressing force. The cost of one piece production was calculated at 18.91 CZK and the production becomes profitable with annual production higher than 19,478 units per year.
