Measurement of ultrasound speed using transmission tomography
Pop, Tomáš ; Kolář, Radim (referee) ; Jiřík, Radovan (advisor)
The study deals with the image reconstructions using the ultrasound propagation speed measuring and it extends the project of the ultrasound transmission tomography organised in cooperation with the research centre Forschungszentrum Karlsruhe (Germany). There were data processed which had been gained with the 3D ultrasound transmission tomography system (3D USCT). The ultrasound propagation speed was measured using the detection of ultrasound ray travelling time from a transmitter to a receiver. There were three new algorithms developed for the detection of an ultrasound impulse and the software generating suitable testing data. The developed algorithms were consequently tried with these data and, then, included into the existing software. All software was developed within the Matlab programming environment.

Non-destructive inspection methods of aircraft selected parts
Kníř, Jakub ; Třetina, Karel (referee) ; Trefilová, Helena (advisor)
Non-destructive testing (NDT) is a broad scientific field. This bachelor thesis provides an insight into NDT’s methods. It can’t embrace the whole field in any case because it’s needed to have knowledge from variety of other scientific fields in order to understand NDT completely. This thesis outlines basic testing methods and their usage for particular components of aircrafts. The thesis also includes a list of Czech and European standards relevant to the topic.
