    Battery systems are increasingly being used for powering ocean going ships, and the number of fully electric or hybrid ships relying on battery power for propulsion and manoeuvring is growing. In order to ensure the safety ...
  • Rabault, Jean; Müller, Malte; Voermans, Joey; Brazhnikov, Dmitry; Turnbull, Ian; Marchenko, Aleksey; Biuw, Martin; Nose, Takehiko; Waseda, Takuji; Johansson, Malin; Breivik, Øyvind; Sutherland, Graig; Hole, Lars Robert; Johnson, Mark; Jensen, Atle; Gundersen, Olav; Kristoffersen, Yngve; Babanin, Alexander; Tedesco, Paulina Souza; Christensen, Kai Håkon; Kristiansen, Martin; Hope, Gaute; Kodaira, Tsubasa; Martins de Aguiar, Victor Cesar; Taelman, Catherine Cecilia A; Quigley, Cornelius Patrick; Filchuk, Kirill; Mahoney, Andrew R. (Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2023)
    Variability in sea ice conditions, combined with strong couplings to the atmosphere and the ocean, lead to a broad range of complex sea ice dynamics. More in-situ measurements are needed to better identify the phenomena ...
  • Midtfjord, Alise Danielle; De Bin, Riccardo; Huseby, Arne Bang (Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2022)
    The presence of snow and ice on runway surfaces reduces the available tire-pavement friction needed for retardation and directional control and causes potential economic and safety threats for the aviation industry during ...
  • Coclite, Giuseppe Maria; Risebro, Nils Henrik (Journal article / Tidsskriftartikkel / AcceptedVersion; Peer reviewed, 2019)
    We analyze a model equation arising in option pricing. This model equation takes the form of a nonlinear, nonlocal diffusion equation. We prove the well posedness of the Cauchy problem for this equation. Furthermore, we ...
  • Christiansen, Snorre H; Gopalakrishnan, Jay; Guzmán, Johnny; Hu, Kaibo (Journal article / Tidsskriftartikkel / AcceptedVersion; Peer reviewed, 2024)
    We construct conforming finite element elasticity complexes on the Alfeld splits of tetrahedra. The complex consists of vector fields and symmetric tensor fields, interlinked via the linearized deformation operator, the ...
  • Ayati, Anis Awal; Steiros, Konstantinos; Miller, A Mark; Duvvuri, Subrahmanyam; Hultmark, Marcus (Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2019)
    Abstract. We introduce an improved formulation of the double-multiple streamtube (DMST) model for the prediction of the flow quantities of vertical axis wind turbines (VAWT). The improvement of the new formulation lies in ...
  • Dahl, Kristina Rognlien; Stokkereit, Espen (Journal article / Tidsskriftartikkel / AcceptedVersion; Peer reviewed, 2019)
    This paper studies a duopoly investment model with uncertainty. There are two alternative irreversible investments. The first firm to invest gets a monopoly benefit for a specified period of time. The second firm to invest ...
  • Truong, Trung Tuyen; To, Tat Dat; Nguyen, Hang-Tuan; Nguyen, Thu Hang; Nguyen, Hoang Phuong; Helmy, Maged (Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2023)
    We propose in this paper New Q-Newton’s method. The update rule is conceptually very simple, using the projections to the vector subspaces generated by eigenvectors of positive (correspondingly negative) eigenvalues of the ...
  • Neshveyev, Sergey; Yamashita, Makoto (Journal article / Tidsskriftartikkel / AcceptedVersion; Peer reviewed, 2018)
    We prove two results on the tube algebras of rigid C*-tensor categories. The first is that the tube algebra of the representation category of a compact quantum group G is a full corner of the Drinfeld double of G. As an ...
  • Ciardo, Lorenzo (Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2019)
    This work introduces a general concept of center for graphs, built on the model of the characteristic set ([12], [14]) of trees. We define it as the set of cycles in a specific directed graph associated with the original ...
  • Agram, Nacira; Øksendal, Bernt (Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2020)
    We study a financial market where the risky asset is modelled by a geometric Itô-Lévy process, with a singular drift term. This can for example model a situation where the asset price is partially controlled by a company ...
  • Weishaupt, Kilian; Koch, Timo; Helmig, Rainer (Journal article / Tidsskriftartikkel / AcceptedVersion; Peer reviewed, 2021)
    We present a fully coupled pore-network/free-flow model providing pore-scale insight into drying processes. We solve the Navier–Stokes equations with component transport in the free-flow region, coupled to a dynamic ...
  • Mortensen, Mikael (Journal article / Tidsskriftartikkel / AcceptedVersion; Peer reviewed, 2023)
    In this paper we describe a generic spectral Petrov–Galerkin method that is sparse and strictly banded for any linear ordinary differential equation with polynomial coefficients. The method applies to all subdivisions of ...
  • Piterskaya, Anna; Miloch, Wojciech Jacek; Mortensen, Mikael (Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2023)
    This paper presents a new efficient algorithm based on the spectral-Galerkin numerical approximations complemented by a magnetohydrodynamics–Boussinesq model and a new solver for studying the development of a Rayleigh–Taylor ...
  • Tseng, Hsian-Hua; Fenglong, You (Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2023)
    We define a new Gromov–Witten theory relative to simple normal crossing divisors as a limit of Gromov–Witten theory of multi-root stacks. Several structural properties are proved including relative quantum cohomology, ...
  • Ravi, Charanya (Journal article / Tidsskriftartikkel / AcceptedVersion; Peer reviewed, 2018)
    We prove a Grothendieck–Lefschetz theorem for equivariant Picard groups of non-singular varieties with finite group actions.
