• An estimation-forecast set-up for iceberg drift prediction 

      Andersson, Leif Erik; Scibilia, Francesco; Imsland, Lars Struen (Journal article; Preprint, 2016)
      Iceberg drift forecasting is challenging. Large uncertainties in iceberg geometry and in iceberg driving forces – current, wind and waves – make accurate forecasts difficult. In this work, a new estimation-forecast scheme ...

      Nikoofard, Amirhossein; Johansen, Tor Arne; Mahdianfar, Hessam; Pavlov, A (Journal article; Preprint, 2014)
      This paper presents a constrained finite horizon model predictive control (MPC) scheme for regulation of the annular pressure in a well during managed pressure drilling from a floating vessel subject ...
    • On small satellites for oceanography: A survey 

      Guerra, Andre G.C.; Francisco, Frederico; Villate, Jaime; Agelet, Fernando; Bertolami, Orfeu; Rajan, Kanna (Journal article; Preprint, 2016)
      The recent explosive growth of small satellite operations driven primarily from an academic or pedagogical need, has demonstrated the viability of commercial-off-the-shelf technologies in space. They have also leveraged ...
    • Past, Present and Future Challenges of the Marine Vessel's Electrical Power System 

      Skjong, Espen; Volden, Rune; Rødskar, Egil; Molinas Cabrera, Maria Marta; Johansen, Tor Arne; Cunningham, Joseph (Journal article; Preprint; Peer reviewed, 2016)
      The evolution of the use of electricity in marine vessels is presented and discussed in this article in an historical perspective. The historical account starts with its first commercial use in the form of light bulbs on ...
