Evaluation of pulse wave velocity in the human body
Mezuláníková, Radka ; Viščor,, Ivo (referee) ; Jurák, Pavel (advisor)
This Mater's thesis deals with the evaluation of pulse wave velocity using multi-channel whole-body impedance cardiography. Data were taken from the group of healthy volunteers whose impedance changes were measured during rest, respiratory maneuvers, tilt and stress exercise. The result of this measurement are values of peaks of pulse wave time shifts towards R-wave. The velocity values towards the thorax electrodes were recalculated on the basis of knowledge about the pulse wave time shifts and the distances from the heart to the scanned locations, which were measured using the arterial segment's lengths.

Distance Practical Education of Electric Machines
Šelepa, Jan ; Huzlík, Rostislav (referee) ; Hájek, Vítězslav (advisor)
This work contains scheme of practical point of distance training in the field of electric machines. It consits of three parts nessesary for consistence of entire work. In first part we have a description of data networks used to communication with virtual laboratory. Further there is a list and description of software fit for our study. These are programs capable of controling measurements, e.g. . LabView, Control Web, TestPoint, ScopeWin etc. In second part we have selection of measurment experiment. As experiment i measured the effectivness of three-phase transformer. The values archieved during the experiment where recorded and processed into form of graph and tables. In last part i used processed results to create functional simulation of measurement using MS Excel software. Further i calculated characteristics for equivalent circuit diagram of the transformer, that where equivalent to the real values measured in laboratory.
