Measurement of non-linear acoustoelastic effect in steel using acoustic resonance
(Doctoral thesis, 2014-09-25)Non-destructive stress measurements of structures are increasingly valued by the industry. Ultrasonic methods have the advantage that acoustic waves propagate with ease through materials, making it possible to probe the ... -
The application of CW and FM sonar technology to detect a decrease in air in the swim bladder of Atlantic salmon, measurements and modeling
(Master thesis, 2022-06-01)Salmon lice and poor surface conditions are challenging for salmon aquaculture. A new innovative preventative solution is to submerge the cages below the sea surface to avoid the surface-dwelling infestation of lice larvae. ... -
Underwater Ultrasonic Transducer Technology. Construction, Characterization and Finite-Element Modelling.
(Master thesis, 2022-03-30)The main objective of this thesis is to construct and characterize ultrasonic transducers. The transducers are constructed to get the information needed for finite element simulations with the wanted accuracy since commercial ...
