Dualband circularly polarized antenna for VHF and UHF band
Urbánek, Tomáš ; Šebesta, Jiří (referee) ; Lukeš, Zbyněk (advisor)
The project is focused on the dualband circularly polarized antenna, which is designed for receiving amateur radio frequencies income 145 and 435 MHz. First the work describes the principles of the antennas, then it focuses on the design and simulation. The antenna is simulated in the program 4nec2 and CST MICROWAVE STUDIO.

Possibilities of improvement of fire properties of insulation materials based on organic fibers
Urbánek, Tomáš ; Třísko, Pavel (referee) ; Zach, Jiří (advisor)
This work is focuses on the modification of organic fiber insulating materials in terms of their reaction to fire after installation into the construction. The target is to find a way to improve the reaction to fire and to at least reach the reaction to fire D.
Study of possibilities of modification of insulators based on natural fibers for improvement of their fire reaction
Urbánek, Tomáš ; Sedlmajer, Martin (referee) ; Zach, Jiří (advisor)
This paper deals with new possibilities of modification of organic (including natural) fibers to improve their reaction to fire used in the production of thermal and acoustic insulators. The aim of the thesis is to achieve a minimum reaction class to fire D in final insulators.
Application of the Simatic control system for the packaging machine control
Urbánek, Tomáš ; Mišinger, Lukáš (referee) ; Knobloch, Jan (advisor)
Masters thesis deals with the SIMATIC, which is the process control system from Siemens. Simatic belongs to the group of so-called programmable logic controllers (English Programmable Logic Controller). It is a microcomputer that processes the instructions in real time. I have designed a control algorithm and HMI visualization in my Masterś thesis. Moreover,my attention is focused on PLC S7 - 300. The S7-313C is used for implementations. The proposed solution has been tested and operated in real conditions
Factors for reoffending and the process of desistance in the context of conditional release

A report based on sociological, criminological, and psychological perspectives, utilizing both qualitative and quantitative data, describing the life trajectories of clients under the supervision of Probation and Mediation Service. The report analyzes the role of individual and social factors in terminating clients´ criminal careers.\n\n
Measurement equivalence of well-being in the European Social Survey (ESS)
Hanzlová, Radka ; Raudenská, Petra (advisor) ; Soukup, Petr (referee) ; Urbánek, Tomáš (referee)
This thesis focuses on measurement invariance of well-being as an important societal topic in large international comparative surveys, but also over time on national data from the Czech Republic. To be able to reliably compare the results of any research, the research must meet certain qualitative criteria, namely reliability, validity and, in the case of international research, comparability (equivalence), which is also the most neglected. Equivalence is most often compromised in attitudinal questions and scales, which is why this thesis focuses on one such concept - well-being. It focuses specifically on testing the multidimensional model of well- being from the 6th Round of the European Social Survey (ESS), and more precisely the "overall model of well-being" developed from it in the process of modification, as the analysis reveals that the ESS model is not appropriate. The equivalence of the overall model of well-being composed of 22 items divided into five dimensions across countries and over time, is tested using two methods: the traditional Multigroup Confirmatory Factor Analysis (MGCFA) as an example for testing exact measurement invariance (EMI) and the more recent alignment method for testing approximate measurement invariance (AMI). The results demonstrate the difficulty of achieving the...
Exploring the Contribution of Isochrony-based Features to Computerized Assessment of Handwriting Disabilities
Gavenčiak, M. ; Zvončák, V. ; Mekyska, J. ; Šafárová, Katarína ; Čunek, Lukáš ; Urbánek, Tomáš ; Havigerová, Jana Marie ; Bednářová, Jiřina ; Galáž, Z. ; Mucha, J.
Approximately 30–60 % of the time children spend in school is associated with handwriting. However, up to 30 % of them experience handwriting disabilities (HD), which lead to a decrease in their academic performance. Current HD assessment methods are not unified and show signs of subjectivity which can lead to misdiagnosis. The aim of this paper is to propose a new approach to objective HD assessment based on the principle of movement isochrony. For this purpose, we used a database of 137 children attending a primary school, who performed a transcription and dictation task, and who were associated with a BHK (Concise Evaluation Scale for Children's Handwriting) score. Employing a machine learning model, we were able to estimate this score with 18 % error. An interpretation of the model suggests that the isochrony-based features could bring new benefits to the objective assessment of HD.
