Multiplatform Application for Speaker Verification
Görig, Jan ; Matějka, Pavel (referee) ; Glembek, Ondřej (advisor)
Bachelor thesis considers speaker recognition without knowledge of spoken message. There are described current feature extraction methods and their evaluation using Gaussian mixture model. The practical output of this work is application for visualization of the recognition process. Developed application is cross platform and it uses Qt and BSAPI libraries.

Biopřístupnost rtuti z ryb a rybích výrobků
Ventrubová, Iva
The work is aimed at determining bioaccessible mercury content of fish and fish products. In the theoretical part is described mercury, health risk, levels of mercury in food, descriptions of each species, fish consumption, chemical composition and nutritional importance of fish consumption, UBM method and methods for the determination of mercury. Firstly, in the practical part the total mercury contents were measured, then there was carried out the UBM test and finally, bioaccessible levels of mercury were analyzed. Analyzed samples of fish and fish products were purchased in the markets of Czech Republic. The analysis of mercury was performed by atomic absorption spectrometer AMA 254. Limits established by legislation (Commission Regulation (EC) No. 1881/2006 as amended) were exceeded in 11 samples. The lowest percentage of mercury bioaccessibility has been found in samples of frozen marlin and the highest percentage were measured at a sample of bigeye smoked tuna.

Biodosažitelné formy vybraných nutrientů v luštěninách
Landauf, Lukáš
This thesis deals with the quantitative determination of bioaccessible contents of selected elements (Cu, Fe, Zn) in legumes: chickpeas, pea, lentil, soybean, bean. The UBM in-vitro test was used for the study of bioaccessible forms. This method simulates human digestion using synthetic gastric juices. Atomic absorption spectrometry was used for the determination of the total content of selected elements in legumes and their bioaccessible contents in gastric and gastro-intestinal human tract. The results showed that copper was the most bioaccessible from green lentils and chickpeas. The lowest bioaccessibility of copper was from soybean. The highest bioaccessibility of zinc was from green lentil, soybean, yellow pea and color bean, but the lowest bioaccessibility was from the black lentils. The best bioaccessibility was from all lentils whereas the lowest iron bioaccessibility was from soybean, yellow pea and color bean. The biggest differences between the gastric and gastro-intestinal phases were in green lentils, yellow peas and chickpeas, while the closest contents in phases were in both types of beans.
