The thesis is focused on analysis of damage extent of dry floors in case of a flood. In the first part it deals with problems of buildings´ stress factors in the point of view of building physics, floor composition and its connection to constructions of timber houses. In the second part it describes testing of three experimental floor samples during simulated flood. It examines and evaluates the behavior and the way of spreading of the leaking water and the effect of moisture on the materials.

The aim of this thesis was to describe the use of debarking head of one grip harvester in the salvage logging. For this purpose, a time study was chosen in which debarking heads with usual tools were compared with debarking heads with debarking sets on five research plots with two machines. The manufacturing process was divided into several operations, which were evaluated separately. Specifically, it was divided into operations: searching, felling, fall of the tree, manipulation, delimbing, and ascertainment. In the next step the quality of debarking was observed, depending on the moisture and on the diameter of logs. Debarking heads were measured during the growing season. It was discovered that the debarking head with debarking set needed twice as much time to process the whole tree as a head with usual tools. Delimbing contributes more than half to this difference. Furthermore, it was discovered that debarking quality does not dependent on the log's moisture at the time of harvest but on the hydraulic pressure of knives and feed rollers. Considering dimensions, the central parts of logs were debarked the best. Following these evaluations, recommendations were made for the practice of using machinery with debarking heads and improving debarking quality.

This thesis deals with soil tillage and its effect on volume and mass moisture of soil. Theoretical part therefore contains information about soil and its properties that affect soil humidity, information about importance of water and water dynamics and characteristic of basic soil treatment operations. Practical part is based on parcel field trial realized at the experimental field station of Mendel University in Žabčice during years 2015, 2016 and 2017. Two basic variants of soil tillage were established: moldboard plowing and reduce tillage to a depth of 15 cm. These two variants of tillage were applied to two types of crop rotation: Norfolk crop rotation system and repetition of monoculture of spring barley. The soil samples were always taken in the barley in two terms: BBCH 30 and BBCH 61 in five depth of the soil profile up to 30 cm. In direct comparsion of tillage variants there was no statistically significant diference. Slightly higher values were measured in plowing variant, especialy in 2016. In the first term of soil sampling had plowing variant significantly higher (p <0,05) volume moisture 15,70 % compared to minimization 14,63 %. In second term had minimization higher volume moisture 10,13 % than plowing variant 10,01 %. When compared individual depths of soil sampling, the lowest moisture content was detected in depth 0–5 cm. There was also difference between tillage variants. Values of mass moisture of minimization variant was 12,87 % and plowing variant 15,78 %. Moisture differences depending on soil tillage and crop rotation was not statistically significant. Mass moisture in barely monoculture was higher in minimization 17,18 % than plowing variant 16,94 %. In norfolk crop rotation system was higher mass moisture 17,16 % in plowing variant compared with minimization 16,50 %.

The aim of this work was to solve problems with excessive humidity in buildings using data analysis. The theoretical part of the work deals with impacts of excessive humidity on the health of building occupants and also the condition of the building structure. Data mining methods including classification, prediction, and clustering are described together with model evaluation and selection. The practical part focuses on hardware platform description and measurement scenarios. Key parameters affecting indoor relative humidity are indoor and outdoor temperature and outdoor relative humidity. The long-term measurement of the mentioned parameters was performed using the set of sensors and BeeeOn system. Measured data was used to design a system for event detection related to a humidity change. The approach to air change regulation in the room was based on natural ventilation.

Soil moisture estimation using Sentinel-1 radar data The main aim of this diploma thesis was to find and quantify the relationship between the intensity of backscatter from the Sentinel-1 radar data and the volume soil moisture at the level of agricultural fields. The research was conducted in three areas, in the first part there were two vegetation-free fields near the Thessaloniki (Greece), and information about soil moisture was obtained from own measurements using a thermogravimetric method. The second part drew data from the freely available ISMN database and the research was carried out on agricultural fields during the vegetation season in northwest Germany. The third part used soil moisture data from the Czech Hydrometeorological Institute (ČHMÚ) and the area of interest was two grassed areas of the airport and one agricultural field. Correlation was measured by calculating the determination coefficient and by using the linear regression an equation for calculating the soil moisture from the radar backscatter was compiled. High dependence has been confirmed when VV polarization with constant surface roughness were examined. In the case of surfaces with varying roughness and vegetation cover, only low correlation was found, similarly with using VH polarization. Key words: radar, SAR, Sentinel-1, soil...
