Node localization on the Internet using artificial coordinate systems
Škvor, Martin ; Molnár, Karol (referee) ; Komosný, Dan (advisor)
This thesis is focused on methods for nodes localization in Internet using latency prediction in synthetic coordinates systems. Thesis also deal with methods, which latency prediction between nodes is based on other systems. Among such a methods particularly belongs King, which uses DNS (domain name service). Furthermore, thesis deal with relevance of overlay networks in latency prediction and their use for different services. Practical part of this thesis concentrates on method for latency prediction in synthetic coordinate system Global Network positioning. There were made two programs for counting coordinates of landmarks and hosts in this system. Measurements and calculations made in this thesis, are focused to determine accuracy of latency prediction of this method and their evaluation is made at the end of thesis.

Meterology of air ions
Škvor, Martin ; Steinbauer, Miloslav (referee) ; Bartušek, Karel (advisor)
This thesis is focus on measuring of air ions concentration, which produce home ionizers. Aspiration condenser has been used for it, because it is able to measure small currents in the order to pA. Spectrum charakteristic has been employed for comparison of measurement results and has been obtained by grafic method from measured saturation charakteristic. Subjects, which the most affect accuracy of measurment air ions concentration and also having impact of air ions concentration at all, are the result of my thesis.
