Wheel rotation in external aerodynamics computations
Páleš, Patrik ; Vančura, Jan (referee) ; Čavoj, Ondřej (advisor)
The aim of the master’s thesis is an investigation of volume mesh quality, turbulent models and models of rotation and their influence on aerodynamic coefficients of rotating wheels. Mesh independence study and near-wall prism layer modelling are also of high importance. Subsequently, the appropriate turbulent model is used for research of wheel rotation on drag and lift on a front and rear axle of the vehicle compared to the stationary case.

Analysis of T wave alternations in programming language C - Radek Poul
Poul, Radek ; Vítek, Martin (referee) ; Rychtárik, Milan (advisor)
The thesis deals with detection of T-wave alternans. The presence of T-wave in surface ECG is recognized as a marker of electrical instability of heart in stage his repolarization, arise increased risk of emergence ventricular fibrillation and sudden cardiac death. The goal of our project is familiarize with methods of detection T-wave alternans. In particular spectral method and spectral method which was realized in variant for running reading values in time (“sliding window”). To suggest a QRS complex detector, localize the T-wave and to make TWA detection using spectral method and modified spectral method. This project is to be made in C language in appropriate user interface.

Search for Axion-Like Particles at the NA62 experiment
Jerhot, Jan ; Kampf, Karol (advisor) ; Hořejší, Jiří (referee)
The thesis instructively presents axions and axion-like particles as a plau- sible extension of the Standard Model of particle physics and discusses also the cosmological implications in the case of their existence as they present one of the most favourable dark matter candidates at given circumstances. The main part of the thesis is concerned with a search for axion-like particles at the NA62 experiment at CERN and a study of the gathered data and its impact on the data analysis.

Hierarchy and human behavior. BDSM as an alternative sexual behaviour.
Jozífková, Eva ; Weiss, Petr (advisor) ; Bob, Petr (referee) ; Zvěřina, Jaroslav (referee)
Preferences for sexual arousal by overstated dominance and submission in sex is categorized as F65.5, sadomasochism, according to ICD, but this behaviour is called BDSM among the general public. The ground of these preferences could be ultimately biological. These preferences reflect behavioural strategy which enables to gain higher reproductive success. Men and women who were sexually aroused by a submissive partner had more male relatives than men and women with other preferences. Contrary to the women, the dominant men reported themselves as more attractive. Women who were aroused by a higher-ranking partner considered themselves more attractive. Sons of couples in which was hierarchical disparity had more siblings than sons of "equal" couples or couples with no hierarchical disparity. Daughters of hierarchically disparate couples had more brothers than daughters of "both dominant" partners. Concurrently, number and gender of offspring as well as self- reported attractiveness are likely to be criteria of the reproductive success in humans. It is also interesting that hierarchically disparate couples, without regard to gender of higher-ranking partner, reached higher reproductive success than "equal" couples. Individuals who preferred higher- or lower-ranking partner were also aroused by...
