Determining Stress Level from Heart Rate Monitoring
Hodulík, Hynek ; Strnadel, Josef (referee) ; Bidlo, Michal (advisor)
This thesis outlines the development of a prototype wearable embedded device intended for stress detection via physiological measurements utilizing an EKG sensor. Communication for the device is facilitated through Bluetooth LE. Accompanying the device is an algorithm designed to estimate stress levels locally based on collected heart rate variability data. Following a comparison of various methods, a multilayer perceptron was selected for stress detection. The proposed solution demonstrates an 85% accuracy rate in stress detection on WESAD dataset.

Design and implementation of wireless charging for embedded systems
Bednařík, Josef ; Bastl, Michal (referee) ; Krejsa, Jiří (advisor)
This thesis deals with the design and realization of wireless power charging circuit for embedded systems. The research section focuses on the various ways and technologies used in applications of wireless power transfer. The theoretical part also briefly characterizes resonant inductive coupling and critical parameters of the transfer. This is followed by realization of various variants of transfer coils and electromagnetic oscillators. Wireless power charging prototype system is created and used for testing purposes to find optimal configuration of resonator. The hardware unit presented in the final part of the thesis exploits microcontroller and implemented software is extended by foreign object detection algorithm along with method to monitor battery charging state.

Journalistic Perspectives on Nordic Identity in Estonia
Niiler, James Viking ; Shavit, Anna (advisor) ; Turková, Kateřina (referee)
Since its restoration of independence in 1991, Estonia has sought to include itself in the Nordic region (Norden) to boost its international reputation and promote its geopolitical interests. However, Estonia's inclusion within Norden is questionable and controversial despite its historical and cultural links to the region. For this Thesis, I conduct a qualitative case study, performing semi-structured interviews with six leading Estonian journalists to ascertain the state of Estonia's national identity vis-à-vis the Nordic region. Contextualizing these interviews by drawing on contemporary history and theories of nation branding, agenda-setting, and constructionism, I conclude that, due to current social and economic factors, Estonia cannot be considered a "Nordic country" at this time. However, Estonia undoubtedly lies within the Nordic region's sphere of influence and is on track for further integration with Norden, due to both internally generated reforms and external geopolitical pressures. Keywords Estonia, national identity, Nordic, journalism, agenda-setting, constructionism, nation branding

Change in retirement policy within the Nordic welfare state
Šmídová, Michaela ; Angelovská, Olga (advisor) ; Šojdrová, Michaela (referee)
My thesis deals with the change of retirement policy in the Nordic welfare state. It focus on the period between years 1990 - 2014, during which the Nordic countries Finland, Norway, Sweden and Denmark were forced to respond to demographic challenges, such as population aging, decrease of economically active population, the increase of old - age dependency ratio and other problems. The main aim of my thesis is to find out if it is possible to observe a markedly different response and acceptance of different changes in the period 1990 - 2014 in the context of pension policy in these countries, or whether the countries responded similarly. The second objective of my work is to undertake a comparison of pension policy within the Nordic countries. As an aspect of comparison, I chose the financial sustainability of pension systems (expected future pension expenditure as % of GDP), the adequacy of pensions (according to the replacement ratio) and the possibility of drawing pensions (ordinary, early) and delay drawing pensions. In my work, I use the method of secondary analysis (especially statistics issued by the OECD and the Eurostat, legal documents and publications). Furthermore, I use comparative method for comparing the situation in different countries according to selected criteria and method of...
