Measurement and diagnosis of vibration induction machines
Hlaváček, Tomáš ; Hájek, Vítězslav (referee) ; Janda, Marcel (advisor)
This thesis deals with noise and vibration in induction machines. First is focused introduction to noise and vibration. Another part is the introduction to electrical machines and vibrations and noise in induction motors. Introduction to the methods of measurement, instruments for measuring and laboratory. Followed by measurement of 3 mass-produced motors. The first sample is to measure vibrations in school labs and compared with measurements at Siemens.

Routing policies and real paths in the Internet
Hlaváček, Tomáš ; Peterka, Jiří (advisor) ; Kruliš, Martin (referee)
Routing policies are now represented by RPSL and by its evolutionary extension called RPSLng. These languages can be used for describing unique routing policy of each autonomous system. Experience shows that even though there are translation tools from RPSL and RPSLng to configuration formats of commonly used routers, the actual network configuration is rarely generated from RPSL sources and routing policy is then perceived as marginal paperwork, which often does not reflect the real network settings. There will be most likely a need for RPSL format change in order to remedy the discrepancies. To support this I present long-term measurements of inaccuracies in routing policies compared to real paths in the Internet. I also present a list of the most frequent problems, and I offer suggestions, how to reform RPSL to improve situation in the long term. Powered by TCPDF (www.tcpdf.org)

Analysis of the popularly educational broadcast by internet television Stream: Gebrian Vs and its comparison with similar tv shows on the same topic on other tv platforms
Hlaváček, Tomáš ; Lokšík, Martin (advisor) ; Šobr, Michal (referee)
The diploma thesis is devoted to freshly emerging TV shows about architecture and public space on the platforms of the two biggest internet TVs in the Czech Republic: Stream.cz and MALL.TV. The work specifically analyzes the following broadcasts: Gebrian VS, Gebrian: Surprising Buildings, Gebrian: PLUS/MINUS, in terms of their distinctive formats. The main purpose of the thesis is to point out the existence of these programs and to identify the formal and genre aspects that shape their unique form. The important part of the research is carried out by comparing the shows based on the platforms on which they are created and which provide different conditions for production. The following theoretical foundations were used: genre theory, presentation of specific genres related to the examined programs, media convergence and internet TVs and their recent production. The qualitative elements, including the visual communication means, which lead to the recognition of the genre construction of a specific TV show, are examined by combined visual and semiotic analysis. Quantitative elements such as tone and footage are analyzed by content analysis. The research reveals some significant differences in the examined TV shows based on a platform they are made on. These are identified as different approaches to...

Směrovací politiky
Hlaváček, Tomáš ; Peterka, Jiří (advisor) ; Spousta, Miroslav (referee)
Routing policies are important aspects of Internet routing. Routing policies can be interpreted or translated in order to help with router configuration and troubleshooting of large scale routing. In this bachelor's thesis I am discussing aspects of writing and interpreting routing policies in RPSL language. The thesis is based on my previous software project BGF, which is a RPSL interpreter and translator written in Perl 5.
