  • Sutherland, Graig J.; Rabault, Jean; Christensen, Kai Håkon; Jensen, Atle (Journal article / Tidsskriftartikkel / AcceptedVersion; Peer reviewed, 2019)
    Sea ice is highly complex due to the inhomogeneity of the physical properties (e.g. temperature and salinity) as well as the permeability and mixture of water and a matrix of sea ice and/or sea ice crystals. Such complexity ...
  • Rabault, Jean (Doctoral thesis / Doktoravhandling, 2018)
    The polar regions are the focus of increased attention due to a combination of environmental, political and economic reasons. In order to help support human activities in the arctic and monitor the state of the ecosystem, ...
  • Rabault, Jean; Kuchta, Miroslav; Jensen, Atle; Reglade, Ulysse; Cerardi, Nicolas (Journal article / Tidsskriftartikkel / AcceptedVersion; Peer reviewed, 2019)
    We present the first application of an Artificial Neural Network trained through a Deep Reinforcement Learning agent to perform active flow control. It is shown that, in a 2D simulation of the Kármán vortex street at ...
  • Sutherland, Graigory John; Halsne, Trygve; Rabault, Jean; Jensen, Atle (Journal article / Tidsskriftartikkel / SubmittedVersion, 2017)
    The attenuation of surface gravity waves is an important process associated with air–sea and wave–current interactions. Here we investigate experimentally the attenuation of monochromatic surface gravity waves due to the ...
  • Rabault, Jean; Fauli, Richard Andre; Carlson, Andreas (Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2019)
    Appendages of seeds, fruits and other diaspores (dispersal units) are essential for their wind dispersal, as they act as wings and enable them to fly. Whirling fruits generate an auto-gyrating motion from their sepals, a ...
  • Rabault, Jean; Sutherland, Graig J.; Jensen, Atle; Christensen, Kai Håkon; Marchenko, Aleksey (Journal article / Tidsskriftartikkel / AcceptedVersion; Peer reviewed, 2019)
    Water wave attenuation by grease ice is a key mechanism for the polar regions, as waves in ice influence many phenomena such as ice drift, ice breaking and ice formation. However, the models presented so far in the literature ...
  • Marchenko, Aleksey; Rabault, Jean; Sutherland, Graig; Collins, Clarence O.; Wadhams, Peter; Chumakov, Mikhail (Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2017)
    Waves propagating below drift ice were observed in the North-West Barents Sea. In-situ measurements of ice and water characteristics were performed with the equipment deployed on the ice and in the water below the ice ...
  • Rabault, Jean; Sutherland, Graigory John; Gundersen, Olav; Jensen, Atle (Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2017)
    Versatile instruments assembled from off-the-shelf sensors and open-source electronics are used to record wave propagation and damping measured by Inertial Motion Units (IMUs) in a grease ice slick near the shore in ...
  • Sutherland, Graigory John; Rabault, Jean; Jensen, Atle (Journal article / Tidsskriftartikkel / SubmittedVersion, 2017)
    The directional wave spectra in sea ice are an important aspect of wave evolution and can provide insights into the dominant components of wave dissipation, that is, dissipation due to scattering or dissipation due to ...
  • Sutherland, Graigory John; Rabault, Jean (Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2016)
    Observations of wave propagation in landfast ice were obtained in Tempelfjorden, Svalbard during March 2015. Wave motion was measured near the ice edge using inertial motion units and consisted of a combination of swell ...
  • Rabault, Jean; Kolaas, Jostein; Jensen, Atle (Journal article / Tidsskriftartikkel / SubmittedVersion, 2017)
    Traditional programs based on feature engineering are under performing on a steadily increasing number of tasks compared with Artificial Neural Networks (ANNs), in particular for image analysis. Image analysis is widely ...
  • Rabault, Jean; Vernet, Julie A; Lindgren, Björn; Alfredsson, P Henrik (Journal article / Tidsskriftartikkel / SubmittedVersion, 2016)
    The admission flow generated by a parallel valve diesel engine cylinder head was investigated by planar and stereoscopic Particle Image Velocimetry in a steady flow test bench through measurements in the swirl and tumble ...
