Alpha activity monitor
Kašpar, Blahoslav ; Sekora, Jiří (referee) ; Chmelař, Milan (advisor)
This work deals with problems of EEG biofeedback and possibilities of its use in therapy. The method of EEG biofeedback helps patients to achieve the state of relaxation. It is a noninvasive treatment modality. The paper also discussed the requirements for each component unit. The main point of a design and construction of Alpha activity monitor, a device implementing EEG biofeedback focused on sensing electrical activity of the brain, specifically alpha waves. Alpha activity is specific and their parameters are taken into account when selecting components and construction equipment. Custom feedback is then for the appearance of alpha activity mediated by the headphones in acoustic form. The work also includes design of electrical circuits and electrical diagram of the overall apparatus including a list of used parts. Electrical diagrams are formed in the EAGLE 6.1.0.

Explantation and analysis of plants
Kašpar, Blahoslav ; Babula,, Petr (referee) ; Valla, Martin (advisor)
The bachelor thesis is focused on the study of antioxidants and detection methods of their antioxidant activity. Antioxidants are substances able to scavenge the activity of oxygen radicals. This ability protects critical cellular structures from oxidation. In nature, plants belong to the important sources of antioxidants. In this thesis we are specifically focused on the detection of antioxidant activity of Japanese knotweed extracts using FRAP (“Ferric Reducing Antioxidant Power”) with automatic UV-Vis spectrometer. The data obtained were treated with the mathematical program developed in MATLAB.
