Quantum key distribution test polygon
Širjov, Jakub ; Horváth, Tomáš (referee) ; Látal, Michal (advisor)
The aim of this masters thesis is to explain quantum key distribution (QKD) and principle of signal transmission in the quantum channel. Further this thesis complains commercial distributors of QKD technologies and their individual appliances. Practical part of the thesis is separated to 3 parts. First part handles transmission of quantum keys in QKDNetsim simulator. Second part takes care of design and creation of a test polygon that allows for testing of many optical network configurations with quantum signal and normal data traffic being transmitted in a single fiber. Multiple simulations of use of various filter types to supress the signal noise in the program VPIphotonics and tested by QKDNetsim are shown in the last part of this thesis.

Quantum and tempo of population ageing process in the twelve countries of the former Soviet Union: Challenges, opportunities and public policies
Mustafina, Marta ; Kučera, Tomáš (advisor) ; Kalibová, Květa (referee) ; Sidorenko, Alexandre (referee)
Quantum and tempo of population ageing process in the twelve countries of the former Soviet Union: Challenges, opportunities and public policies Abstract Population ageing is an omnipresent phenomenon which brings along unprecedented challenges to socio-economic development, especially to employment, social security and public health sectors. The broad goal of this doctoral thesis was to demonstrate that it is time to recognize the importance of population ageing and its dynamics even in the countries with relatively young population structures and to take urgent action through implementation of corresponding policy interventions in order to mitigate and eliminate the upcoming negative consequences and utilize potential opportunities. Research on population ageing in both more and less developed countries is abundant. However, amidst numerous studies, countries of the former Soviet Union remain largely overlooked. Besides, the quantum and tempo of population ageing have not been adequately addressed in the existing literature worldwide. This research addresses, to the best of our knowledge for the first time, those issues. Holistic approach to gap analysis was adopted to guide this study. The analysis was performed in three steps. The first step incorporated the identification and analysis of the observed...

Testing Polygon For Quantum Key Distribution
Širjov, Jakub
The article explains issues in QKD and their sources. It next describes principle of QKDoperation and its individual parts that are required for its function. Part of the article includes simulationsfrom QKDNetsim and NS-3 that show possibilities of the simulation, that were used to createexemplary simulations for future check of QKD traffic on the test polygon.

Ontology of Interaction
Machová, Světlana ; Semrádová, Ilona (advisor) ; Kalábová, Helena (referee) ; Hogenová, Anna (referee)
In this dissertation we propose a novel ontological point of view representing inner dimension of being and its interaction based on the phenomenology, quantum physics, psychoanalytic methodology and cognitive metaphor theories. Empirical findings about the phenomenology of interaction, gained from the associative experiment, open a new dimension of scientific research and interreligious discussion. Comprehension system of inner semantics leads us to a deeper understanding of the world of being. Essential Self interaction. described by cognitive metaphor and allows us identification of universal structure hidden beyond the language. Acquired linguistic data suggest that mind's metaphoric self-reflection semantics closely correlate with a concept of entangled quantum particles and light binding phenomena. This theory gave us a unique opportunity to visualize the probabilistic picture of mind itself within an interdisciplinary approach of cognitive and philosophical studies. In this work, we combine theory of physics and philosophy of language. Language, as a bridge between the two worlds: quantum and material, offers us the possibility of insight into inner reality and approach our awareness of being in a clear and undistorted form. Speech as a speech of being is woven into the context of...

Tempo and quantum of population ageing in the world: development opportunities and challenges
Mustafina, Marta ; Kučera, Tomáš (advisor) ; Sokol, Daniel (referee)
Tempo and quantum of population ageing in the world: development opportunities and challenges Abstract This diploma thesis aims to identify and describe the differentiation of the scale and dynamics of the ageing process in the world at sub-regional level and to develop a typology of those sub-regions and selected countries in terms of mentioned characteristics of population ageing. Furthermore, relatively homogenous groups of countries have been distinguished based on the cluster analysis of social conditions in the context of ageing in order to access their readiness to face further development of the phenomenon. Major development opportunities and imminent challenges associated with population ageing have been evaluated in the end. The results show that the timing and extent of age structure changes are very closely related. Countries that have undergone longer demographic transitions experienced longer demographic windows of opportunity that allowed them to reap the benefits of demographic dividends and to develop better social conditions as a result. Rapidly ageing societies from developing regions, on the contrary, have less time and resources to counteract the challenges resulting from the demographic changes where timely measures and policies have to be prioritized by policymakers.

Comprehension system of inner semantics leads us to a deeper understanding of the world of being.
