Secure Transport of NetFlow and IPFIX Records
Štěpánek, Adam ; Grégr, Matěj (referee) ; Podermański, Tomáš (advisor)
This bachelor thesis deals with an IP flow based data network monitoring system. It presents the architecture of the NetFlow based monitoring, explains the basic terms, the NetFlow protocol and its alternatives. Further, weak spots of the monitoring systems are determined and a conceptual solution is proposed. This solution is implemented and described in detail. Finally, testing methods and results are discussed and the possibilities of further development and optimization are proposed.

Design of EMC optical converter
Štěpánek, Adam ; Hruboš, Zdeněk (referee) ; Krutílek, David (advisor)
Master's thesis is focused on designing optical converter for EMC measurement transfering signal through noisy enviroment. First part contains analysis of electromagnetic interference and its coupling and measurement, especially types of probes for interference maesurement. Next part passing through designing of optoelectric and electrooptic converter with digital intensity modulation. Last part is about realization of optical converter.

Libraries for MSP430G2 microcontrollers
Štěpánek, Adam ; Fedra, Zbyněk (referee) ; Štohanzl, Milan (advisor)
This thesis solves a issue with libraries for microcontrollers MSP430 using them for interfacing internal peripheries such as serial buses or ADC convertor. And also external devices with support of this communication protocols, for example EEPROM memories and expander, or with other interfaces including real time circuit and 8x8 LED matrix display.

Space filling curves
Štěpánek, Adam ; Hencl, Stanislav (advisor) ; Pyrih, Pavel (referee)
Peano curves are continuous mappings from the unit interval [0, 1] onto the n- dimensional square [0, 1]n , n ∈ N. There are many such curves and therefore we focuses especially on the Hilbert curve. We informally outline its geometrical interpretation and then we describe the construction in R2 by writing a number in a quaternary form. For such defined mapping we prove that it is a Peano curve and that it is 1/2 - Hölder con- tinuous. In conclusion, using the Haussdorf dimension, we show that there is no Peano curve in Rn that is also α - Hölder continuous for α > 1/n. 1

Representation of opponents in first-person shooter video games
Štěpánek, Adam ; Švelch, Jaroslav (advisor) ; Švelch, Jan (referee)
Work focuses on representation of opponents in first-person shooter video games. It aims to discover tools, which developers of video games use to choose specific enemies for their games and in which way they present them. First-person shooters are used for this purposes because players have closest visual contact with opponents in this genre. The aim of this work is to describe most typical opponents in video games and to find out why this exact enemies are usualyy the most portrayed. Special attention is paid to video games which used original attitude for creating enemies. Work than focuses on most frequent stereotypes in opponents presentation, mostly racial and national, which are used by developers and what function they have. Than it gives room for critics of such stereotypes and tries to estimate if these critics can result in some changes in the future. Video games which created controversy by representation of specific enemies are subject of next topic. These games often put players in position of moral dilemma. On the base of research from literature and analysis of video games this work focuses on main reasons of representation of concrete enemies and what emotional impact it can have on players.

Portyal of Barack Obama in ČTK agency in 2009
Štěpánek, Adam ; Trunečková, Ludmila (advisor) ; Osvaldová, Barbora (referee)
The aim of this bachelor thesis is to analyze the portrayal of American President Barack Obama in his first year in the office by Czech press agency ČTK. The road of Barack Obama as first Afro-American ever to become President of the USA is described in the first chapter. The second chapter describes ČTK as institution with focus on forms of production. The third chapter discourses about how ČTK informed about personality of Barack Obama during 2009 with emphasis on key moments, such as his visit to the Czech Republic. Special attention is dedicated to public researches which explored popularity of Barack Obama. His popularity at the beginning of 2009 was very high. From the previous cases, the popularity usually dropped down significantly. This was confirmed also in this case. The reason for this was in high expectations by public and also by first presidential moves of Barack Obama.
