Development of Non-invasive Ultrasound Inspection Techniques through Steel
Rommetveit, Tarjei (Doktoravhandlinger ved NTNU, 1503-8181; 2011:254, Doctoral thesis, 2011)Using normal incident, pulse-echo ultrasound is a well-established approach in the non destructive testing and evaluation community for measuring wall thickness and detecting defects. If the sensors are permanently installed, ... -
On the Efficiency of Data Communication for the Ultramonit Corrosion Monitoring System
Rommetveit, Tarjei (Master thesis, 2006)Ultramonit is a system under development for permanent installation on critical parts of the subsea oil- and gas pipelines in order to monitor the corrosion continuously by using ultrasound. The communication link which ... -
