Causal interaction analysis of cardiovascular signals
Tiurina, Mariia ; Kolářová, Jana (referee) ; Svačinová, Jana (advisor)
Application of the non-invasive methods to detection of the baroreflex sensitivity is a correct way to evaluate the functions of cardiovascular system. This master’s thesis describes the theoretical informations about the problem of baroreflex sensitivity from anatomical, patalogical and clinical views. Theoretical knowledges are foundation for mathematical description of some methods to detection of baroreflx sensitivity in time, frequency and information dimensions. In the practical part of the master’s theses are presented two methods of BRS detection – sequence method based on finding the specific sequences of time series signals and method of application bivariante autoregressive model. Both of methods are implemented in MATLAB. The results of testing data on real data are discussed.

The Naturalization of Consciousness and the Meaning of Subjectivity
Toráčová, Pavla ; Moural, Josef (advisor) ; Hill, James (referee) ; Marvan, Tomáš (referee)
The thesis deals with the problem of the existence of consciousness in the physical world. It denies the approach that is prevailing in the contemporary philosophy of mind that treats the phenomenal consciousness and intentionality separately. The position held in this thesis is to claim that the phenomenal character of consciousness and intentionality are inseparable and that it is impossible to understand the former without understanding the latter, and vice versa. The problem of the existence of consciousness in the physical world is viewed as the problem of the existence of (conscious) intentionality in the physical world. With the aim to achieve an analysis of intentionality that would keep its phenomenal character and the first person point of view, and, at the same time, shed light on its realization in the physical world, thoughts of Peter Strawson, G. E. M. Anscombe, Tim Crane, Colin McGinn and John Searle are discussed. The result is an outline of intentionality that allows to explain the fundamental level of intentionality as a physical process and the higher levels of intentionality as a development of the fundamental level. Two principles are crucial for this approach: the development of intentionality from the fundamental level to the higher level is comprehensible only if we keep the...

Lex Aquilia and delict damnum iniuria datum of roman law
Svátek, Jan ; Falada, David (advisor) ; Šejdl, Jan (referee)
I Lex Aquilia and delict damnum iniuria datum of roman law Abstract The subject of this thesis is the Lex Aquilia and the delict of unlawfully caused damage (damnum iniuria datum) contained in this law. The aim of the thesis is a comprehensive analysis of the Lex Aquilia as one of the most important Roman laws and the introduction of damnum iniuria datum contained in it as a universal delict for cases of damage claims in a wide range of cases of killing animals or slaves, cases of damaged things or complete destruction of property. The first part of the thesis serves as an explanation of key concepts from a general point of view, which are necessary to grasp the subject. The concepts of obligation and delictual liability, Roman categorisation of delicts into delicta privata and crimens, and the role of lawsuits (actio) and standing in Roman law are introduced. Furthermore, the sources of the regulation of delict law, primary sources including the Corpus Iuris Civilis, and also various authors most notably Roman lawyer Ulpian, are presented in a brief manner. The aim of the work is achieved in the second part of the thesis by analysis of interrelated institutes, whether they are specific lawsuits of the Lex Aquilia, or introduction of diverse ways of committing this delict by killing (occidere), damaging the...

David Hume's analysis of causality
Pakandl, Martin ; Rybák, David (advisor) ; Hauser, Michael (referee)
This diploma thesis is focused on David Hume's analysis of causality. The two major philosophical works about this topic are A Treatise of Human Nature and Enquiries concerning Human Understanding. The first chapter is about intellectual background which Hume came from when he is dealing with cause-effect problem. At that time there were two main epistemological theories: rationalism and empirism. Both will be discuss there. The next chapter is about Hume's way of thinking about human understanding. This chapter is important for us beacuse there are many terms which will be useful for understanding causality. Crucial role plays The Theory of Ideas, according to each content of a mind has a source in experience. The first perceptions are called impresions and their copies are called ideas. Ideas are processed by memory and imagination. There are two categories of contents of human understanding: relations of ideas and matters of facts. We will focus on matters of facts because they are based on causality. Hume as a empirist is searching for a source of idea of causality in our experience. He finds out that we cant find it in objects of our minds themselves, but is based on relations among them. These relations are: contiguity, constant conjunction, priority of time in the cause before the effect 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.

Causes of Effects and Effects of Causes
Zemánková, Lucie ; Maciak, Matúš (advisor) ; Antoch, Jaromír (referee)
The thesis deals with an associative and causal relationship between two different random phenomena and presents basic statistical methods for investigation of these relationships. Firstly it focuses on demonstrating the association between phenomena and shows that finding a causal relation between phenomena requires appropriate randomization of the system or intervention in the system. After intervening in the system, it is no longer possible to observe all situations, so-called counterfactual observation, but the causal relationship can still be demonstrated using appropriate technical procedures and theoretical assumptions. The thesis further summarizes different ways of representation of causal structures, first by means of graphs, where basic methods of estimating the causal structure are presented, and later by structural equations that already capture the quantitative measure of causal relations.
