Pulse Oxymeter in LabVIEW
Synek, Josef ; Chmelař, Milan (referee) ; Čmiel, Vratislav (advisor)
One of the most important vital functions of the human body is providing sufficient oxygen to all its parts. Oxygen in the blood binds to hemoglobin and it is transported to tissues. Oxymetry is non-invasive method for measuring the amount of oxygen bound to hemoglobin. Oxygenated hemoglobin and deoxygenated have different absorption characteristics for light of different wavelengths. Therefore, pulse oxymetry transmits tissue with red and infrared light. Signal passing through the tissue is affected by the absorption properties of hemoglobin and heart pulse. These signals are measured and the ratio of their size allows us to calculate blood oxygen saturation.

System for measurement of aerobic stability of forage
Synek, Josef ; Sekora, Jiří (referee) ; Harabiš, Vratislav (advisor)
Aerobic stability is a term which nutritionists use to define the length of time that forage remains stabil and don‘t degrade. Once fermentation is completed and the forage is exposed to air during feeding or during storage (leaky silos, poor packaging) increases the temperature of the forage initiated by yeasts or lesser extent by the action of some bacterias. This temperature is measured using temperature sensors and it is compared with the ambient temperature of the surroundings. Aerobic stability is given as the time, for which the forage temperature rises by 3°C above ambient temperature.
