Signal of heartbeats – laboratory tool
Vyplel, Vojtěch ; Vychodil, Josef (referee) ; Sigmund, Milan (advisor)
This work deals with the development of a laboratory device for measuring heart rate. The work will describe the basic anatomy of the heart and the origin of heartbeats. There are also methods for measuring heart rate. A sensor for sensing a heart rate in a laboratory device is described in detail. The work presents the circuit solution of the laboratory device and measurement of its functionality. Furthermore, the work describes the application for the evaluation of heart rate and written instructions for laboratory exercises.

Plethysmography for retinal video processing
Plavcová, Daniela ; Valterová, Eva (referee) ; Kolář, Radim (advisor)
Sight is one of the five human senses and is very important for exploring near and far surroundings. However, this is prevented by various eye defects, which may be related to the vascular system of the retina and the pulsations that are observable on it. This work deals with the study of the relationship between the mentioned pulsations and glaucoma. To search for connections between these two aspects, video recordings from the retina are used, the pulsation of which is further worked in the form of a 1D signal, especially in the spectral region.

Comparison of methods of basal metabolism determination
Kosková, Martina ; Coufalová, Klára (advisor) ; Hráský, Pavel (referee)
Title: Comparison of individual methods of basal metabolism determination Objectives: The aim of the work is to compare the individual methods of basal metabolism. These values were measured by indirect calorimetry, plethysmography, bioelectric impedance and predictive equations. Methods: The research was attended by 31 people, including eight men and twenty-three women. All participants of my research were aged 21-30 years. None of the participants was a professional athlete, they were all healthy and none of the women were pregnant or had menstruation. The indirect calorimetry, bioelectronics impedance device Tanita MC - 980 and BOD POD were used to collect the data. Basal metabolic rates were calculated from the prediction equations by Harris & Benedict, Fleisch's equation and Schofield's equation using measured anthropometric values. Results: The results of the methods that have been used for this group of people vary, but the difference is not significant. If we choose as a reference method indirect calorimetry, we can't replace it by any other method. The results for other methods are not significantly different, so we can replace one method with another, except indirect calorimetry. From calculations, we also found out that fat free mass greatly influences the results of basal metabolic rate...
