  • Spagnol, Simone; Hoffmann, Rebekka; Herrera Martínez, Marcelo; Unnthorsson, Runar (Elsevier BV, 2018-07)
    Translating visual representations of real environments into auditory feedback is one of the key challenges in the design of an electronic travel aid for visually impaired persons. Although the solutions currently available in the literature can lead ...
  • Balan, Oana; Moldoveanu, Alin; Moldoveanu, Florica; Nagy, Hunor; Wersenyi, Gyorgy; Unnthorsson, Runar (American Foundation for the Blind., 2017-03)
    As the number of people with visual impairments (that is, those who are blind or have low vision) is continuously increasing, rehabilitation and engineering researchers have identified the need to design sensorysubstitution devices that would offer ...
  • Helgadottir, Asdis; Lalot, Sylvain; Beaubert, Francois; Pálsson, Halldór (MDPI AG, 2018-10-10)
    Swirling flow has been shown to increase heat transfer in heat exchangers. However, producing swirl while not presenting a severe pressure drop can be a challenge. In this paper, a desired shape of guidance blades for laminar swirl flow is determined ...
  • Skúlason Kaldal, Gunnar (University of Iceland, School of Engineering and Natural Sciences, Faculty of Industrial Engineering, Mechanical Engineering and Computer Science, 2019-05-20)
    High-temperature geothermal wells are drilled in stages and constructed of several concentric steel casings that are cemented over their entire external surface for sealing and structural support purposes. The structural integrity of such casings is ...
  • Jóhannesson, Ómar I.; Balan, Oana; Unnthorsson, Runar; Moldoveanu, Alin; Kristjánsson, Árni (MDPI AG, 2016-06-27)
    The Sound of Vision project involves developing a sensory substitution device that is aimed at creating and conveying a rich auditory representation of the surrounding environment to the visually impaired. However, the feasibility of such an approach ...
