    • High-Q bulk acoustic wave resonators for RF filter applications 

      Nguyen, Ngoc Thi Bich (Doctoral dissertations at the University of South-Eastern Norway;24, Doctoral thesis, 2019)
      This thesis proposes a novel design method for optimizing bulk acoustic wave (BAW) resonators, including film bulk acoustic resonators (FBAR) and solidly mounted res-onators (SMR). The purpose is to enhance their quality ...
    • Flexible electrochemical sensor platform 

      Søpstad, Sindre (Doctoral dissertations at the University of South-Eastern Norway;54, Doctoral thesis, 2019)
      Bringing an electroanalytical assay from the laboratory to the level of a commercially or clinically viable product often requires substantial cost, effort and time. While the real value may lie in the assay and sensor ...
    • Die-attach for high-temperature electronics 

      Larsson, Andreas (Doctoral thesis, 2019)
      Applications in harsh environments push the boundaries for electronic systems. High temperatures put great stress on electronic components. The die-attach is an enabling component that makes the system work. It needs to ...
    • Heat generation in underwater transducers 

      Wild, Marcus Sebastian (Doctoral dissertations at the University of South-Eastern Norway;38, Doctoral thesis, 2019)
      Acoustic transducers are used for a variety of applications, ranging from medical to maritime uses. In the maritime sector, underwater transducers can be used for appli- cations such as seabed mapping, fishing and ...
    • Evaluation of resolution enhancement in shifted superimposed projection displays: Simulations and experiments 

      Hansen, Svein Arne Jervell (Doctoral dissertations at the University of South-Eastern Norway;60, Doctoral thesis, 2020)
      Spatial resolution is one of the key performance parameters of a projected display, and the projector industry continuously aims to increase it. Projector resolution is traditionally based on the resolution of the spatial ...
    • Layer-specific strain and strain rate : Estimation using miniature transducers attached to the epicardium 

      Nguyen, Thuy Thu (Doctoral dissertations at the University of South-Eastern Norway;68, Doctoral thesis, 2020)
