    • A Simple Browser-based 3D-Sketching Framework for Novice and Infrequent Users 

      Sandnes, Frode Eika; Lianguzov, Yuriy (Chapter; Peer reviewed, 2017)
      Modelling in 3D is considered time-consuming and difficult, requiring special training. There are currently no 3D modelling user interface conventions. This paper thus presents a framework for simple 3D modelling based ...
    • A Simple MVC-Framework for Local Management of Online Course Material 

      Sandnes, Frode Eika; Eika, Evelyn (Journal article; Peer reviewed, 2017)
      Managing online materials for large classes can be time-consuming and error prone. In particular, it can be challenging to manage long lists of students, lecture progress, and auditorium schedules as these often change on ...
    • A solution of the Mitra Paradox 

      Grøn, Øyvind (Journal article; Peer reviewed, 2016)
      The “Mitra paradox” refers to the fact that while the de Sitter spacetime appears non-static in a freely falling reference frame, it looks static with reference to a fixed reference frame. The coordinate-independent nature ...
    • Absence and Presence of Faces in Videos during the COVID19 Lockdown 

      Sandnes, Frode Eika (DSAI: Development and Technologies for Enhancing Accessibility and Fighting Info-exclusion;DSAI 2020 - The 9th International Conference on Software Development and Technologies for Enhancing Accessibility and Fighting Info-exclusion, Conference object, 2021-12-02)
      The COVID-19 outbreak forced the educators to deploy digital online learning giving rise to a range of new situations. The phenomenon of undergraduate students not activating their cameras during video lectures has been ...
    • Absorbers as detectors for unbound quantum systems 

      Selstø, Sølve (Physical Review A (PRA);Vol. 106, Iss. 4, Peer reviewed; Journal article, 2022-10-19)
      Complex absorbing potentials are frequently employed in quantum calculations. One of the advantages that such absorbers provide is the ability to attenuate outgoing waves in simulations of unbound systems, thus allowing ...
    • The Accessibility of MOOCs for Blind Learners 

      Krolak, Aleksandra; Chen, Weiqin; Sanderson, Norun Christine; Kessel, Siri (Association for Computing Machinery (ACM);, Chapter; Peer reviewed, 2017)
      The development of Massive Open Online Courses (MOOCs) has provided unique learning opportunities for many people. In the meantime, the lack of accessibility in some MOOCs has also created barriers for ...
    • Accessibility of MOOCs for Blind People in Developing Non-English Speaking Countries 

      Ferati, Mexhid; Mripa, Njomza; Bunjaku, Ridvan (Chapter; Peer reviewed; Chapter, 2016-07-08)
      Besides the globally popular MOOCs, localized MOOCs specific to a region or language are also emerging. These specialized MOOCs often aim to address specific needs that are typically unaddressed by the ...
    • Accessible Driver Announcement in Public Transportation: A Solution based on Speech-to-Text and Display
