Testing of the accuracy of the heights determined by GNSS
Kordasová, Klára ; Drápela, Zdeněk (referee) ; Kuruc, Michal (advisor)
The aim of this thesis is to test the accuracy of the heights measured by GNSS RTK with service providers CZEPOS and Trimble VRS Now. The thesis deals with precise of height measurement with the influence of surrounded obstacles, such as multipath, fading with the tall buildings, presence of high-voltage lines, limited shadow horizons at the edge of the forest, and measurement under the ideal conditions. The work also deals with the comparison of the period initialization of these monitored conditions. In the locations mentioned a network of test points was built. For measuring GNSS Leica System 1200 apparatus was used. It was measured always five times in five-second epochs and three times twenty-second epochs for each provider in five locations and thirty points during the mornings and afternoons. For independent height comparison the technical levelling was used. The outcome can be applied in practical use.

Surface depressions of the bony pelvis in relation to childbirth and pregnancy
Medvedevová, Elina ; Rmoutilová, Rebeka (advisor) ; Brůžek, Jaroslav (referee)
This bachelor's thesis describes the depressions of the pelvic bony surface, which are described in the literature as "indicators of childbirth", and summarizes the data on whether pelvic bony depressions can be associated with pregnancy and childbirth, and what other factors may be involved in the formation of these depressions. The "birth indicators" include the preauricular grooves and the dorsal fossa of the pubic bone. Historically, they have been attributed to the course of pregnancy and childbirth when physiological and hormonal changes occur. However, more recent studies and new research methods have attributed the development of these depressions not only to pregnancy but also to pelvic shape, age, increased BMI of the person, physical activity, or medical complications. A variety of factors can contribute to the development of bone surface depression in both women and men. For this reason, so-called "birth indicators" cannot be considered a reliable indicator of completed pregnancy and childbirth, and secondary use of knowledge of these depressions in sex estimation, especially by application in forensic sciences. However, it should be noted that the difference in the frequency of depression between the sexes is significant, as the incidence of such depression is more frequent and marked...

Standing Tall Pays Off: A Meta-Analysis of Height Premium
Juračková, Martina ; Havránková, Zuzana (advisor) ; Polák, Petr (referee)
As has been demonstrated by empirical research, height is an important physical feature impacting various aspects of the life of an individual. This thesis deals with the relationship between height and income, also referred to as height premium. With the help of modern meta-analytic methods, we aim to quantitatively summarize the empirical evidence on the impact of height on income. After introducing the topic of height premium, data collection and methodological framework, we test for publication bias. The analysis is conducted on 1084 height premium estimates collected from 67 studies. The results of publication bias testing indicate that height premium literature contains positive publication bias which persists even after we control for additional variables capturing study characteristics or, in other words, the heterogeneity of collected estimates. Based on Bayesian Model Averaging results, we conclude that geographical factors, the longitudinal nature of the dataset, restriction of the dataset with respect to gender, or adding a gender control variable into the regression are the most important factors explaining the variability of height premium effects.

Dendrologické hodnocení biomasy v biokoridoru Vracov
Procházka, Martin
This thesis is dealing with dendrological assessment of biomass in biocorridor Vracov. This thesis contains data from the period 2013 - 2015. The data was measured on permanent research plots, and later the data was compared with the previous data. The target of this thesis was the detection of the growth the trees and shrubs on agricultural soil. This thesis includes the measurements of circumference and heights dimensions. The number of trees and shrubs was counted on all permanent research plots and health conditions were determined. Graphs, tables and pictures are components of this thesis.

Biomechanical characteristics in Axel Paulsen jump variations in figure skating
Hrdličková, Kristýna ; Sedláčková, Marie (advisor) ; Šteffl, Michal (referee)
Title: Biomechanical characteristics in Axel Paulsen jump variations in figure skating Objectives: The aim of this thesis was to measure the biomechanical characteristics (height and length) of the single Axel Paulsen jump. The jump was measured from two inputs, namely from a standing position (from zero initial velocity) and from a running position (from a single backward translation). Methods: For the thesis, a quantitative research method was used, namely the measurement of selected parameters of the Axel Paulsen single jump. The measurements were performed on a sample of 16 female figure skaters, in the age range of 10 -16 years. Bar graphs were created for each variable as part of the analysis. The best trials were always selected for quantitative analysis. Furthermore, means and standard deviations were calculated. Due to the size of the measured sample, non-parametric methods were used to test the hypotheses. The Wilcoxon matched pairs test was used, and error plots were generated. Data analysis and graphs were created using IBM SPSS Statistics 24 statistical software. Results: It was found that the single Axel Paulsen jump length values are longer in the run-up version. For the Axel Paulsen single jump height values, it was found that the jump height on the average is 0.5 cm higher in the...

Demands of the Teacher's Proffesion on the Teachers' Voice
Králová, Michaela ; Tichá, Alena (advisor) ; Koverdynský, Luděk (referee)
This dissertation thesis deals with the demands on teachers' voice and proper use of voice in the teacher's profession. The whole thesis consists of two parts: theoretical and practical. The theoretical part is divided into nine sections: the anatomy and physiology of the vocal tract, voice developement, comparison of spoken and singing voice, psychological impact on voice, voice defects and hygiene, voice reeducation, methods of voice diagnostics and voice acoustics. The research part presents the findings of acoustic voice measurement. Students (only women) of Faculty of Education in Prague participed in the research. The objective of this part was to asses the quality of students' voice and their voice readiness for future teaching.

Comparison of bodytypes, weight, hight and It's relationship to performance
Pecha, Marek ; Jebavý, Radim (advisor) ; Hojka, Vladimír (referee)
Topic: Comparison of bodytypes, weight, hight and It'srelationship to performance Goal: The goal is to compare body types of world elite athletes from past and present in athletict hrows. Second goal is to compare weight and height in different disciplines. Methods: Research in specialized sources, analyse and comparison athletes body types. Comparison of body types with performances in disciplines. Results: Wecreated a dokument which contain if body proportions are affecting on a throwers performance in short and long therm. From our results is obvious that hight and weight are really matters in some disciplines. We found a strong dependence in javelin throw and in shot put. In disciplines where prevails rotation moves is dependence much lowor there is practicaly none. In the second part we foundout differences in hight and weight in throws through the time. Keywords: bodytype, long performance, athletic throws, body composition,height, weight, BMI

Relations among elements of a triangle
Machovcová, Lucie ; Zhouf, Jaroslav (advisor) ; Dvořák, Petr (referee)
This thesis summarizes not only most of the basic components and qualities of a triangle but it also brings pieces of information about triangles which are not usually taught at elementary and high schools. The aim of the thesis is to make readers acquainted with those components and to show differences between them. There are solved constructional and arithmetical problems in the last chapter. These problems utilize relations described in the thesis. The topic of these relations goes beyond mathematical curriculum of high schools. A part of the thesis is made of pictures to imagine better the terms described and the relations of components. All of the pictures are designed in a geometrical program called GeoGebra. Key words: triangle, side, angle, altitude, median, area, perimeter.
