  • Interpolation in wavelet spaces and the HRT-conjecture 

    Berge, Eirik (Peer reviewed; Journal article, 2021)
    We investigate the wavelet spaces Wg(Hπ)⊂L2(G) arising from square integrable representations π:G→U(Hπ) of a locally compact group G. We show that the wavelet spaces are rigid in the sense that non-trivial intersection ...

    Rouhani, Majid; Lillebo, Miriam Størseth; Farshchian, Veronica; Divitini, Monica (Peer reviewed; Journal article, 2021)
    Professional Development (PD) organizations provide training programs for computer science teachers through teacher PD. Programming as part of a teacher’s PD has grown in importance in K-12 education. As a result, an ...
  • Code Reuse and Formative Assessment in Secondary Education 

    Nystad, Niklas Joakim; Rouhani, Majid; Divitini, Monica (Peer reviewed; Journal article, 2021)
    Code reuse is a widely accepted practice in software engineering. Not surprisingly, the practice is becoming more and more widespread also in the context of computing education. This paper explores the use of code reuse ...
  • Efficient Mixing of Arbitrary Ballots with Everlasting Privacy: How to Verifiably Mix the PPATC Scheme 

    Gjøsteen, Kristian; Haines, Thomas Edmund; Solberg, Morten Rotvold (Peer reviewed; Journal article, 2021)
    The long term privacy of voting systems is of increasing concern as quantum computers come closer to reality. Everlasting privacy schemes offer the best way to manage these risks at present. While homomorphic tallying ...
  • Probabilistic fatigue model for design and life extension of mooring chains, including mean load and corrosion effects 

    Lone, Erling Neerland; Sauder, Thomas Michel; Larsen, Kjell; Leira, Bernt Johan (Peer reviewed; Journal article, 2022)
    A probabilistic model for mooring chain fatigue damage is developed based on the S–N approach. The effects of mean load and corrosion condition on the fatigue capacity of the chains are included by adopting a parameterized ...
  • Artificial Intelligence and Business Value: a Literature Review

  • In-Service Teachers’ Attitude Towards Programming for All 

    Rouhani, Majid; Jørgensen, Victor (Peer reviewed; Journal article, 2021)
    Coding instruction has increased widely throughout primary and secondary education in many countries, and educators are just beginning to understand the complexities of teaching students to code. A question raised is whether ...
  • Inverse response behaviour in the bright ring radius measurement of the Czochralski process II: Mitigation by control 

    Bukhari, Syeda Halima Zahra; Hovd, Morten; Winkler, Jan (Peer reviewed; Journal article, 2021)
    This is the second part of a two-article series investigating the presence of an inverse response in the measurement of the ingot radius in the Czochralski process for monocrystalline silicon production, when the ingot ...
  • Quality is in the Salient Region of the Image 

    Jamshidi Seikavandi, Meisam; Amirshahi, Seyed Ali (Peer reviewed; Journal article, 2021)
    The ultimate goal in any proposed Image Quality Metrics (IQMs) is to accurately predict the subjective quality scores given by observers. In the case of most IQMs the quality score is calculated by pooling the quality ...
  • How Good is Too Good? A Subjective Study on Over Enhancement of Images 

    Azimian, Sahar; Torkamani-Azar, Farah; Amirshahi, Seyed Ali (Peer reviewed; Journal article, 2021)
    For a long time different studies have focused on introducing new image enhancement techniques. While these techniques show a good performance and are able to increase the quality of images, little attention has been paid ...
  • Combination of Backstepping and Reduced Indirect FCS-MPC for Modular Multilevel Converters 

    Hamayoon, Saad; Hovd, Morten; Suul, Jon Are Wold (Chapter, 2021)
