Influence of stress on pilot abilities
Procházková, Hana ; Chlebek, Jiří (referee) ; Šplíchal, Miroslav (advisor)
The diploma thesis focuses on measuring the pilot´s stress during real flights. The general methodology is established. This methodology should be followed when measuring stress. This methodology is applied on students and pilots during a real flight. Results show that with the gradual data collection, this methodology could contribute to the long-term goal of setting the tolerable level of stress and help streamline flight training.

The Sensor Systems Design and Optimization for Energy Harvesting Applications
Žák, Jaromír ; Husák, Miroslav (referee) ; Bajer, Arnošt (referee) ; Hubálek, Jaromír (advisor)
Dissertation thesis is focused on using alternative energy sources called energy harvesting. This thesis offers a solution to problems with autonomous powering of sensor networks if primary power source recovery is impossible. In these cases, energy of the external power (e.g. temperature, light, motion) should be used. Proposed solution should be especially used in the field of medical applications (e.g. cochlear implants, pacemakers, insulin pumps). Long time monitoring of the personal health status is also possible when employing automated sensor systems. In this work, there is state of art review relating to the low power energy sources for an alternative powering of sensor systems. It was observed that existing systems are almost prepared for the implementation of energy harvesting power sources. The energy harvesting power sources have been developed by numerous researcher teams around the world, but there are only a few variants of power management circuits for effective energy gaining, storing and using. This area has a huge potential for the next research. The issues regarding to the distribution of gained energy are solved on the complex level in the thesis. For these purposes, a new simulation model of the whole system (fully implantable artificial cochlea) including its subcircuits was developed in the SPICE environment. It connects independent subcircuits into a single comprehensive model. Using this model, a few novel principles for energy distribution (e.g. Charge Push Through technique) was developed. In the near future, these techniques are also applicable to the design of versatile sensor systems.

Influence of wearable electronics on the healthy lifestyle of students of the University of South Bohemia in the field of Health education
JEŽKOVÁ, Štěpánka
The aim of the presented bachelor thesis is to map the current state of use of wearable electronics by students of the University of South Bohemia in the field of Health Education, to analyze the impact of these devices on the healthy lifestyle of students. Answer the questions of whether students are more motivated to use regular electronics in connection with the use of this electronics and whether they have acquired new knowledge. In the theoretical part of the thesis, I deal with the topic of the current lifestyle, then define in more detail the important factors of a healthy lifestyle and characterize the study field of Health Education. The last chapter is focused on individual devices of wearable electronics. In the empirical part, I use a questionnaire survey to analyze the impact of ownership and use of wearable electronics on the healthy lifestyle of students and from the obtained, statistically evaluated data I subsequently interpret the results of the research itself. The processed data revealed that wearable electronics, which are used to monitor and record data on physical activity, are used by students of Health Education. Out of the total number of 63 students studying Health Education, 45 students participated in the research. In the area of this electronics, 80% of respondents use some of the devices. 7% of respondents are at least prospectively considering buying equipment. Of these active users, more than 2/3 of the respondents were shown to be motivated by wearable electronics for more frequent and regular physical activity. 81% of users confirmed the expansion of knowledge and the acquisition of new information in the field of a healthy lifestyle. It is undoubtedly clear from the answers that wearable electronics had a positive effect on the lifestyle of many respondents.
