Software for analysis of body surface temperature changes before and after exercise
Remenárová, Veronika ; Bernard, Vladan (referee) ; Vlk, Daniel (advisor)
This thesis focuses on creating an application software for monitoring and analyzing changes in body surface temperature before and after exercise test by the means of contactless thermography. Initial, theoretical part of this thesis talks about principles and possible scenarios, in which one could employ infrared thermography followed by physiology of the exercise load and concludes with an observation of the changes in body surface temperature while focusing on the actions that take place during the exercise test. Practical part of the thesis comprises of the exercise test and building of the application software for the analysis of the acquired thermographic visual output. The application software offers 2 kinds of analyses: general and under-load, while it aims to provide evaluation in both cases based on user-selected areas of interest. Last chapter of this thesis includes final output with commentary and eventual usage of the under-load experiment and application software in practical use.

Comparison of selected hemodynamic parameters and body surface temperature between athletes and normal population after exercise
Remenárová, Veronika ; Forýtková, Lenka (referee) ; Vlk, Daniel (advisor)
The thesis deals with monitoring of hemodynamic parameters, body surface temperature of population and changes in these physical parameters caused by physical exercise. This thesis includes literary research from mentioned area, focusing mainly on pulse, blood pressure, blood flow, its velocity and body surface temperature, in meaning of their resting values, methods of measurement and their changes caused by exercise. Twenty women, 10 sportswomen and 10 women from normal population will undergo two types of exercise test to monitor changes in chosen hemodynamic parameters and to compare different groups of women. This part is followed by quantitative and statistical analysis of the measured data.

Iinfrared thermography and handheld ultrasound doppler during exercise test
Urbanová, Lucia ; Vlk, Daniel (referee) ; Staffa,, Erik (advisor)
Semester project elaborates theoretical part of bachelor thesis, which is going to process results of measurements performed by infrared thermography and Doppler ultrasonography during physical tests on volunteers. The theoretical part contains basics of infrared thermography, where physical quantities, laws and principles are explained. The basic of Doppler ultrasonography are explained as well. In practical part will be statistically analyzed data measured by a thermal imager and Doppler ultrasonography. Study group of people will form students aged from 18 to 25 years. Thermographic and Doppler measurements will be performed before exercise and after exercise. The aim is to find a correlation between processed data.

The possibilities of water quality improvement in small catchments by landscape planning from the viewpoint of nutrients
VLK, Daniel
This bachelor thesisis is focused on the issue of increasing concentration of nutrients in the watershed, and subsequently in other natural ingredients, especially water . This thesis dealt with the most problematic nutrients that have affected the water quality such as nitrogen and phosphorus. Subsequently, there is cycle of both the above-mentioned substances described in detail. Particularly those elements get into the environment in excessive amount due to human activities. Therefore their natural cycles are distorted, and that can lead to natural habitats impairment.

Measurement and analysis of the blood flow in peripheral vessels by ultrasound Doppler methods
Lepš, Milan ; Sedlář, Martin (referee) ; Vlk, Daniel (advisor)
Nowadays, the Doppler ultrasonography is an essential part in medicine. With it, we can observe acoustic showoff some tissue associated with Doppler measurement of blood flow parameters. It is still using Doppler devices with a continuous signal which are although structurally and technically simpler, but they are suitable for measuring the speed and volume of blood flow in peripheral blood vessels of the upper and lower limbs. There are calculated physiological parameters from the flow curves that are clinically used for assessing the state of blood supply to the body part. We can determine many values from the flow curves, like peripheral resistance, blood flow in systole and diastole, medium speed, etc. Study group of people are male and female students from 18 to 20 years. Doppler measurements have been performed before physical exercise and after physical exercise.
