Bc. Marek Budiš Comparison of X-ray microtomography possibilities of application in metrology with conventional approaches Master thesis, Institute of production machines, systems and robotics, BUT FME Brno This master thesis is focused on the analysis of metrological possibilities of using computer X-ray microtomography methods in the industry. The work contains a description of the methods, equipment and measurement. Listed are the main advantages of using X-ray tomography in metrology in comparison with coordinate measuring machine. The work deals with the measurement accuracy of microtomography machine GE V|tome|x L 240, analyzing sources of instrument uncertainty and its quantification. The work was also devised a practical table for the calculation of uncertainty of measurement. The practical part was also measuring on real samples of the industry.

This diploma thesis describes realization and testing on-the-fly measurement using tracking interferometer. This measurement enables to achieve higher amount of measured points and decrease time of machine tool calibration. Calibration and verification values of machine parameters, as well as time of measurement and other details of this method are compared with results of conventional method called trigger. To evaluate the quality of volumetric compensation created from calibration values, we use verification measurement of circular interpolation.

The formulated study is focused on the analysis and quantification of the accuracy–parameters related to the abrasive process. The scope of the mentioned study deals with the identification of the abrasive process, technological influence and accuracy–parameters of abrading surfaces. In the final part of this study, there is a practical sample described with respect to the technological influence on the resulting accuracy–parameters of the abrasive process.

Title: Accuracy in throwing on the vertical target depending on combination of crossed and identical hand - eye laterality in selected population of FTVS students. Objectives: The aim of this study is determination of any disparity in success rate and darts distribution among selected strongly right-handed and left- handed population of male and female students of FTVS in throwing on the vertically positioned target. Methods: The main research method was used descriptive association method. A total of 60 individuals were enrolled in the study. We used Musalek's test battery (2013) containing questionnaire part, preferential tasks and proficiency tests to define particular sidedness of individual probands. Further a specific task of the throw at the target was employed. For data analysis we used descriptive statistics methods, chi-squared test goodness of fit, analysis of variance, tetrachoric correlation and level of substantive significance expressed by Cohen's d. Results: The results indicated that left-handed individuals did not show a significantly better accuracy in throwing at the vertically positioned target compared with right-handed individuals. It seems that gender is an important factor that affects the level of accuracy in the throws on target because male showed significantly better...

Title: History of skydiving - precision landing Objectives of work: The aim of this work is to map complexly and integraly the history of skydiving with a focus on racing discipline of precision landing. Due to insufficient number of relevant compact resources and web sites, so the work becomes the first file that holds the issue in a comprehensive manner and develop a unified overview of the analysis problem. Method: This is a theoretical work, the kernel of the work will be at tracing specialized publications and websites, collecting information, filtering the relevant data in their comprehensive use. Results: Objective of thesis was largely achieved. It turned out that the topic is very broad to draw up a detailed summery of the entire history of the research question. The topic was therefore processed generally and is more like a preview than a perfect description. Intended overview was given. Key words: Skydiving, parachute, competitive discipline, precision landing, history.

Title: Progress of discipline precision landing based on the development of a circular parachute Objectives of work: The aim of this work is to map the history of skydiving with a focus on racing discipline of precision landing and on the development of a circular parachute.

The thesis deals with the question of using available sources of elevation data for the evaluation of topographic factor in estimating the amount of water erosion in the area. Work compares the results with consideration to the origin of the data, the accuracy and resolution of the digital terrain model, which is interpolated from the source data. The calculation of topographic factor in ArcGIS will be confronted with the results of the Universal Soil Loss Equation (USLE). The frequency of compliance will tell us which data source and digital terrain model resolution is the most suitable for determining the topographic factor.

This diploma thesis titled ?Application of the geodetical method and GNSS method for land location? deals with the topic of laying reference points of lands using the traditional geodetical method and the method integrating the GNSS technology. The comparison of the used methods focuses mainly on the productivity, efficiency and accuracy of the geodetical work. The initial preparatory works included reference points evaluation and recognition. After that a coordinate frame of reference points was established for the use of the geodetical method. The final layout of the reference points was performed by means of the geodetical method as well as the GNSS method employing the permanent measuring station Czepos. The average coordinates fault was taken into account when the accuracy of the coordinates position was analyzed. The laid reference points were used to maintain the actual land cadastration.

The goal of the submitted thesis was setting out newly proposed borders of land with GNSS technology in the context of the land consolidation. For a locality was selected cadastral area Kamenný Újezd near the České Budějovice. The procedure of each activity was related to the demarcation of the total of 78 points with GNSS method. The thesis revealed a time demands and a lower accuracy and while showed reduced effectiveness of using. The accuracy was related to the mean value coordinate error. The comparison was carried out with the geodetic method. At the same time to be solved a question of usefulness and meaningfulness stake out work for the purpose of land consolidation and the relationship of new owners to the new borders of land.
