Internet nodes localization using synthetic coordinate systems
Švéda, Jaroslav ; Jelínek, Mojmír (referee) ; Komosný, Dan (advisor)
This thesis deals with predicting the latency between two network nodes, such as the two stations, two servers or server and station. The main reason for adoption of effective latency prediction techniques is the elimination of network load caused by unnecessary repeated transmissios or by direct measurement of the latency. Of the many proposed methods of latency estimation, this thesis is focused on methods using artificial coordinate systems with primary focus on the Vivaldi algorithm. Characteristics of the latency prediction methods and properties of various coordinate systems used in practice are evaluated. The issue of the number of dimensions of space defined only by the latency matrix between nodes is also mentioned. Furthermore, some other systems, based on logical clustering of nearby nodes, are mentioned. Description of simulation software VivaldiMonitor developed as part of the thesis is included. The primary purpose is analysis of the behavior of overlay networks implementing Vivaldi algorithm with less than a few hundred nodes. The Vivaldi algorithm is assessed by several simulations carried out using the aforementioned software.

Development of Test Batteries for Diagnostics of Motor Laterality Manifestation - Link between Cerebellar Dominance and Hand Performance
Musálek, Martin ; Chytráčková, Jitka (advisor) ; Tichý, Jiří (referee) ; Bryden, Pamela (referee)
The aim of this study is to contribute to the standardization of the new diagnostic tools assessing the motor manifestations of laterality in adults and children aged 8 to 10 years, both in terms of determining the theoretical concept and the selection of appropriate items, and the verification of structural hypotheses concerning the design of acceptable models, including the diagnostic quality of individual parts of the test battery. Moreover in this study we try to suggest new approach in assessing of motor laterality manifestation by means of relationship between cerebellar dominance and hand performance. The first part of this thesis deals with the concept of laterality, its manifestations and meaning in non-living systems and living organisms. As a human characteristic, laterality is manifested in a variety of functional and structural asymmetries. This part also discusses ways of diagnosing motor manifestations of laterality and the issue of cerebellar dominance, including its reflection in the form of asymmetry of the extinction physiological syndrome of upper limbs. The second part focuses on the process of the standardization study, the statistical method of structural equation modelling, and the actual design of test battery construction. The last part of this thesis presents the results...

New Ecological Paradigm as a research approach in the Czech Republic: An analysis of environmental attitudes of Czechs
Vaněk, Jiří ; Ščasný, Milan (advisor) ; Soukup, Petr (referee)
This thesis focus on the New Ecological Paradigm (NEP) and its measurement instrument New Ecological Paradigm scale. Thesis introduces the New Ecological Paradigm as opposite type of thinking to the Human Exemptionalism Paradigm and provides historical context of the creation of the revised version of the New Ecological Paradigm scale. We carried out a secondary analysis of the data from survey about the European climate change policy acceptance conducted by Ščasný et al in year 2015. Thesis then examined the extent to which people from the Czech Republic, the Great Britain and the Poland endorse the New Ecological Paradigm and found out that the Czechs have the higher environmental concern than people from the Great Britain and the Poland. Furthermore, this thesis use Cronbach`s and factor analysis to discover, that the New ecological paradigm scale is internally consistent yet multidimensional instrument in case of the three surveyed countries. Regression analysis discovered that not only gender and age are significant socio-demographic predictors for the NEP results as income, education, size of municipality and current occupation are also relevant across the three surveyed countries. Lastly, regression analysis verified that the direct correlation between the general environmental values measured by the...
