Wireless transmission interference modeling (AWGN, Rayleigh, Rice fading channels)
Hloušek, Tomáš ; Gleissner, Filip (referee) ; Mikulka, Jan (advisor)
This thesis describes and models wirelesss transmission intereferences in real communication channels. A signal received on a fading channel is subjected to a multiplicative distortion and to the usual additive noise. Real channel adds to the signal noise and fadings. Gaussian noise is a result of channel awgn. Fadings is implicated by multipath propagation of signal in Rayleigh and Rician channels. Main goal of this project is to program BERsolve, which is created in tool GUIDE in Matlab. User program BERsolve makes it possible to analyse bit error rate and symbol error rate for some types of channel models, which are defined by standard COST207. BERsolve offers some other functions i.e. display time behaviour, constellation diagram and spectrum. This program provides us with an overview representation of problem by multipath interferences in communication channels.

Sázení na loterie a sportovní události z pohledu behaviorální ekonomie
Mikulka, Jakub ; Koblovský, Petr (advisor) ; van Koten, Silvester (referee)
This thesis deals with the relationship between mood and behavior of bettors using a dataset provided by a betting company, Chance a.s., which operates in the Czech Republic. We consider three types of proxies for the mood: weather in regions, sport successes and the results of elections, and we build a fixed effect model to estimate the effect of mood on betting behavior. We provide strong evidence that the weather proxy has a significant effect on daily turnovers of the betting company and there also seems to be an effect of sport optimism. On the contrary, we failed to find any impact of elections. The results show that better mood tend to discourage clients from sports and lottery betting which is consistent with the increase in risk aversion or the depletion of a common self-control resource due to active mood regulation attempts. Additionally, we provide an evidence that the intra-month cycle in turnovers corresponds to liquidity constraint of bettors which disproves the permanent income hypothesis.

Statistics-based classification on tissues in the mandibular region
Marcon, P. ; Bartušek, Karel ; Mikulka, J. ; Gescheidtová, E.
The authors present a statistical evaluation of T1-weighted and T2-weighted images of healthy and diseased human tissues. In each patient, the statistical data were evaluated from several tissues, namely the bone, bone marrow, muscle, fat, white matter and gray matter tissue types. Based on the acquired statistical data, we compiled new statistics. In the given tissue samples, we evaluated the following statistical quantities: standard deviation (s.d.), skewness, and kurtosis. The box plots and a small statistical database were created. This database is currently used to determine the tissues.

Processes of real and nominal convergence in enlarged EU
Mikulka, Jakub ; Bič, Josef (advisor) ; Abrhám, Josef (referee)
This bachelor thesis deals with real and nominal convergence in the European Union. Particular attention is devoted to differences in convergence processes between New and Old Member States of the European Union. Beta and sigma convergence is tested at the levels of states, regions NUTS 1 and NUTS 2 during period 1995-2006. The results are put in theoretical background of Solow-Swan model and New Economic Geography. Furthermore, Balass-Samuelson effect and his incidence is presented.
