      The rapid development of deep learning has given rise to new and improved ways of performing image segmentation. However, there are not much work done specifically for the task of segmenting remotely sensed imagery. The ...
    • Airplane braking friction on dry snow, wet snow or slush contaminated runways 

      Klein-Paste, Alex (Journal article; Peer reviewed, 2018)
      Airplanes need tire-pavement friction during taxiing, take-off and landing. The presence of snow reduces the friction and therefore there is need to understand how much friction can be expected on the different types of ...
    • Airtightness Development in Large Timber Buildings: Case Study of a Zero-Emission Building in Norway 

      Svenning, Lise; Moschetti, Roberta; Kvande, Tore; Gullbrekken, Lars; Time, Berit (Peer reviewed; Journal article, 2023)
      Large timber buildings are increasingly used in the Nordic countries because of low greenhouse gas emissions and good access to timber. There is however uncertainty about the airtightness of the envelope of such buildings ...
    • Airtightness estimation – a state of the art review and an en route upper limit evaluation principle to increase the chances that wood-frame houses with a vapour- and wind-barrier comply with the airtightness requirements 

      Relander, Thor-Oskar; Holøs, Sverre Bjørn; Thue, Jan Vincent (Peer reviewed; Journal article, 2012)
      High airtightness is particularly important in order to achieve energy efficient buildings. Of this reason airtightness estimation is of interest. Over the past 30 years researchers have worked on airtightness estimation. ...
