Comparison of scan patterns in dynamic tasks
Děchtěrenko, Filip ; Lukavský, Jiří (advisor) ; Nyström, Marcus (referee) ; Paluš, Milan (referee)
Eye tracking is commonly used in many scientific fields (experimental psychology, neuroscience, behavioral economics, etc.) and can provide us with rigorous data about current allocation of attention. Due to the complexity of data processing and missing methodology, experimental designs are often limited to static stimuli; eye tracking data is analyzed only with respect to basic types of eye movements - fixation and saccades. In dynamic tasks (e.g. with dynamic stimuli, such as showing movies or Multiple Object Tracking task), another type of eye movement is commonly present: smooth pursuit. Importantly, eye tracking data from dynamic tasks is often represented as raw data samples. It requires a different approach to analyze the data, and there are a lot of methodological gaps in analytical tools. This thesis is divided into three parts. In the first part, we gave an overview of current methods for analyzing scan patterns, followed by four simulations, in which we systematically distort scan patterns and measure the similarity using several commonly used metrics. In the second part, we presented the current approaches to statistical testing of differences between groups of scan patterns. We present two novel strategies for analyzing statistically significant differences between groups of scan patterns and...

Spatial and temporal scales of atmospheric dynamics
Jajcay, Nikola ; Paluš, Milan (advisor) ; Masoller, Christina (referee) ; Dijkstra, H.A. (referee)
DOCTORAL THESIS Nikola Jajcay Spatial and temporal scales of atmospheric dynamics Abstract Earth climate, in general, varies on many temporal and spatial scales. In particular, climate observables exhibit recurring patterns and quasi- oscillatory phenomena with different periods. Although these oscillations might be weak in amplitude, they might have a non-negligible influence on variability on shorter time-scales due to cross-scale interactions, recently observed by Paluš[1]. This thesis supplies an introductory material for inferring the cross-scale information transfer from observational data, where the time series of interest are obtained using wavelet transform, and possible information transfer is studied using the tools from information theory. Finally, cross- scale interactions are studied in two climate phenomena: air temperature variability in Europe, in which we study phase-amplitude coupling from a slower oscillatory mode with an 8-year period on faster variability and its effects, and El Niño/ Southern Oscillation where we observe a causal chain of phase-phase and phase-amplitude couplings among distinct oscillatory modes.

Tick-borne encephalitis - from pathogenesis to therapy
PALUS, Martin
The proposed thesis contributes to the knowledge about tick-borne encephalitis and its pathogenesis. The thesis describes pathogenesis and immunopathogenesis of tick-borne encephalitis, impact of host's genotype in clinical course determination, immune response of patients with acute tick-borne encephalitis, the mechanism of tick-borne encephalitis virus migration into central nervous system and virus interaction with cells of neurovascular unit as well as potential medical interventions.

Data boxes and their impact on processes in commercial companies
Paluš, Matej ; Pour, Jan (advisor) ; Basl, Josef (referee)
Data boxes and eGovernment have become a very important part of communication with the public administration recently. I dedicated my thesis to problem of data boxes in Czech Republic. I focused on period after 2011, because the period before I described in my bachelor thesis. The practical part consists of task of effective implementation data boxes to enterprise (small firm up to 20 employees). The important part of thesis is description of key processes associated with data boxes and evaluating their efficiency. The solution of practical task should serve as a guide for anyone who wants to implement data boxes into company. The procedure described in practical part of this diploma thesis helps companies in proper using of electronic documents.

The role of genetic background of the host on the pathogenesis of tick-borne encephalitis
PALUS, Martin
We examined the influence of the host genetic background on the pathogenesis of tick-borne encephalitis. We determined virus titers in organs and serum in different time intervals post-infection for different ways of inoculation. We also stated mean survival times and antibody production in different strains of mice infected with tick-borne encephalitis virus. Moreover, differences in expression of immunologicaly important genes in brains of infected mice were compared.

ICT in public administration
Paluš, Matej ; Voříšek, Jiří (advisor) ; Stiegler, Petr (referee)
This bachelor thesis is devoted to eGovernment in Czech Republic with a major focus on project of data boxes. In the first part I compare some of the selected electronic services of eGovernment in EU countries with analysis of level that was reached. This includes clarification of the Czech Republic's position in the ranking of EU countries in meeting of computerization services. The second part is already dedicated to the situation of implementing data boxes in Czech Republic. My purpose is to introduce large and significant project for the computerization of public administration. I want to refer the legal aspects and risks associated with data boxes, problems with their implementation but also evaluate the benefits of this project. The last part is about the situation in the Slovak eGovernment and possible visions for the future. The most important of this part will be the analysis of every possible risks that could jeopardize the implementation of data boxes in Slovakia. I want to focus on legislative aspects of the eGovernment and also the situation after that act was applied.
