      Jakobsen, Jasna Bogunovic; Cheynet, Etienne; Snæbjörnsson, Jonas Thor; Mikkelsen, Torben; Sjøholm, Mikael; Angelou, Nicolas; Hansen, Per; Mann, Jakob; Svardal, Benny; Kumer, Valerie-Marie; Reuder, Joachim (Peer reviewed; Journal article, 2015-12-02)
      Wind velocity measurement devices based on the remote optical sensing, lidars, are extensively applied in wind energy research and wind farm operation. The present paper demonstrates the relevance and potential of lidar ...
    • The COTUR project: remote sensing of offshore turbulence for wind energy application 

      Cheynet, Etienne; Flügge, Martin; Reuder, Joachim; Jakobsen, Jasna Bogunovic; Heggelund, Yngve; Svardal, Benny; Saavedra Garfias, Pablo Andres; Obhrai, Charlotte; Daniotti, Nicolo; Berge, Jarle; Duscha, Christiane Anabell; Wildmann, Norman; Onarheim, Ingrid Husøy; Godvik, Marte (Journal article; Peer reviewed, 2021)
      The paper presents the measurement strategy and data set collected during the COTUR (COherence of TURbulence with lidars) campaign. This field experiment took place from February 2019 to April 2020 on the southwestern coast ...
    • Improved long-span bridge modeling using data-driven identification of vehicle-induced vibrations 

      Cheynet, Etienne; Daniotti, Nicolo; Jakobsen, Jasna Bogunovic; Snæbjörnsson, Jonas Thor (Journal article; Peer reviewed, 2020)
      The paper introduces a procedure to automatically identify key vehicle characteristics from vibrations data collected on a suspension bridge. The primary goal is to apply a model of the dynamic displacement response of a ...
    • The influence of terrain on the mean wind flow characteristics in a fjord 

      Cheynet, Etienne; Liu, Shengnan; Ong, Muk Chen; Jakobsen, Jasna Bogunovic; Snæbjörnsson, Jonas Thor; Gatin, Inno (Journal article; Peer reviewed, 2020)
      Flow conditions in complex terrains such as fjords are highly three-dimensional and thus not properly captured by the wind flow models developed for homogenous terrains. In the present study, we explore the potential of ...
    • Observations of bridge stay cable vibrations in dry and wet conditions: A case study 

      Daniotti, Nicolo; Jakobsen, Jasna Bogunovic; Snæbjørnsson, Jonas Thor; Cheynet, Etienne; Wang, Jungao (Journal article; Peer reviewed, 2021-04-01)
      The characteristics of wind- and rain-wind-induced vibrations of bridge stay cables are studied by using ambient vibrations records acquired on a cable-stayed bridge. Mean wind speed and wind-cable angle, as well as the ...
    • Potential and challenges of wind measurements using met-masts in complex topography for bridge design: Part I - Integral flow characteristics 

      Midjiyawa, zakari; Cheynet, Etienne; Reuder, Heinrich Joachim; Ágústsson, Hálfdán; Kvamsdal, Trond (Journal article; Peer reviewed, 2021-03-10)
      The paper investigates the local topographic effect on the mean and integral flow characteristics recorded by sonic anemometers mounted on tall masts near the shoreline of three different Norwegian fjords. Two years of ...
    • Potential and challenges of wind measurements using met-masts in complex topography for bridge design: Part II – Spectral flow characteristics 

      Zakari, Aoudou Midjiyawa; Cheynet, Etienne; Reuder, Joachim; Ágústsson, Hálfdán; Kvamsdal, Trond (Journal article; Peer reviewed, 2021)
      This study quantifies the influence of the local topography on sonic anemometer measurements mounted on tall met-masts deployed in Norwegian fjords. This assessment is done by analysing the second-order structure of ...
    • Recommendation on use of wind lidars 

      Reuder, Joachim; Cheynet, Etienne; Clifton, Andrew; van Dooren, Marijn Floris; Gottschall, Julia; Jakobsen, Jasna Bogunovic; Mann, Jakob; Palma, Jose; Schlipf, David; Sjøholm, Mikael; Trujillo, Juan-Jose; Thobois, Ludovic; Würth, Ines; Zasso, Alberto (Research report, 2021)
