Non destructive sensors for measurement of the very slow change of the biological structure dimensions
Kostka, Filip ; Kubásek, Radek (referee) ; Friedl, Martin (advisor)
The aim of this thesis is to record a very small increment of the perimeter trees in one day using dendrometr. As the sensor is used tensometer strain gauge, which the deformation of its shape also changes its resistance and it is used subsequently to monitor the recording of growth. Data from dendrometr are handles by digital multimeter, which is synchronized with the PC, where further processing occurs date. This semester project also deals with the thermal expansion of metal parts of dendrometr and ambient conditions during the experiment.
