Eco-design in electronics - directives and tools for optimizing
Chlup, Marian ; Brzobohatý, Jaromír (referee) ; Szendiuch, Ivan (advisor)
This diploma thesis deals with the problem of ecological design and optimization of electrical products. The theoretical part describes the ecodesign legislation and assessment tools. The practical part is deals with created software for evaluation and comparison of electrical products. I analyzed three flash drives, which are commonly used. In these flash drives analyze packages and these packages were evaluated and compared with software. The last section describes the problems of availability of the necessary information.

Energy cost of slacklining
Klaus, Jan ; Baláš, Jiří (advisor) ; Hráský, Pavel (referee)
Title Energy expenditure of slackline walking Objectives The aim of this study was to investigate the energy expenditure of slacklining in intermediate and advanced slackliners. Methods In this observatory study, 19 slackliners (10 intermediate, of which 7 men and 3 women, 9 advanced, of which 7 men and 2 women) completed experimental energy expenditure measurement of slacklining using indirect colorimetry. The MetaMax 3B metabolic analyzer (Cortex Biophysik, Germany) was used to determine respiratory parameters and the heart rate monitor (Polar Electro OY, Finland) was used to determine the heart rate (HR). Comparative statistical tools were used in the data analysis. Results Relative energy expenditure of 0,471 kJ·min-1 ·kg-1 was found in intermediate slackliners and 0,377 kJ·min-1 ·kg-1 in advanced slackliners in walking on a 10 m long slackline at a constant speed of 15 m·min-1 . In the static standing on slackline, the relative energy expenditure was found to be 0.368 kJ·min-1 ·kg-1 in intermediate slackliners and 0.289 kJ·min-1 ·kg-1 in advanced slackliners. The weighted arithmetic mean for HR in men and women walking on the slackline at 15 m·min-1 was at 67.3% of the predicted HRmax (220 - age for men, 226 - age for women). The MET value in the advanced group (n = 10) was set at 5.15, and in...

The possibility of measuring the intensity of physical activity based on the number of steps and heart rate data in adults, school and preschool children
Jarco, Michal ; Buchtelová, Aneta (advisor) ; Musálek, Martin (referee)
The number of people suffering from overweight or obesity is growing worldwide. One of the most important factors contributing to weight gain is the lack of exercise, which is nowadays caused mainly by a sedentary lifestyle. Exercise is therefore very important for our health and in children it also significantly contributes to the proper development of their cognitive functions. This thesis is focused on the possibility of using data about total number of steps for a certain time unit (per minute or throughout the day) to classify the intensity of physical activity (especially moderate and vigorous) it also marginally deals with the possibility of evaluating the intensity of physical activity using heart rate data. According to internationally recognized standards, an adult should spend at least 30 minutes (60 minutes is recommended for children) a day in moderate intensity physical activity, or 15 minutes (30 minutes for children) in vigorous intensity physical activity. Many studies focused on adults agreed that the cadence of around 90-110 steps per minute is optimal for achieving moderate intensity of physical activity, but the height, age and gender of individuals also play an important role. For children, this value is around 120 steps per minute, but age is much more important than gender....
