• An experimental analysis of the impact of thermal protective immersion suit and angle of heel on individual walking speeds 

      Azizpour, Hooshyar; Galea, Edwin R.; Erland, Sveinung; Batalden, Bjørn-Morten; Deere, Steven; Oltedal, Helle Asgjerd (Peer reviewed; Journal article, 2022)
      The cold environment of Polar Regions introduces additional challenges to maritime safety in situations where it becomes necessary to abandon a vessel. The Polar Code requires all vessels operating in Polar Regions to be ...
    • Induced drag in two dimensions in ideal fluids 

      Meyer, Runald Walter; Erland, Sveinung (Peer reviewed; Journal article, 2019)
      In this paper we suggest a model for how a significant part of the drag forces on two-dimensional objects can be derived using the circulation that is naturally maintained around the objects. We assume incompressible and ...
    • Lorentzian geometry and variability reduction in airplane boarding: Slow passengers first outperforms random boarding 

      Erland, Sveinung; Kaupužs, Jevgenijs; Steiner, Albert; Bachmat, Eitan (Peer reviewed; Journal article, 2021)
      Airlines use different boarding policies to organize the queue of passengers waiting to enter the airplane. We analyze three policies in the many-passenger limit by a geometric representation of the queue position and row ...
    • Lorentzian-geometry-based analysis of airplane boarding policies highlights “slow passengers first” as better 

      Erland, Sveinung; Kaupužs, Jevgenijs; Frette, Vidar; Pugatch, Rami; Bachmat, Eitan (Peer reviewed; Journal article, 2019)
      We study airplane boarding in the limit of a large number of passengers using geometric optics in a Lorentzian metric. The airplane boarding problem is naturally embedded in a (1+1)-dimensional space-time with a flat ...
    • The mesoscale order of nacreous pearls 

      Gim, Jiseok; Koch, Alden; Otter, Laura M.; Savitzky, Benjamin H.; Erland, Sveinung; Estroff, Lara A.; Jacob, Dorrit E.; Hovden, Robert (Peer reviewed; Journal article, 2021)
      A pearl’s distinguished beauty and toughness are attributable to the periodic stacking of aragonite tablets known as nacre. Nacre has naturally occurring mesoscale periodicity that remarkably arises in the absence of ...
    • Onset of smoldering fires in storage silos: Susceptibility to design, scenario, and material parameters 

      Villacorta, Edmundo; Haraldseid, Ingunn; Mikalsen, Ragni Fjellgaard; Hagen, Bjarne Christian; Erland, Sveinung; Kleppe, Gisle Yngvar Romslo; Krause, Ulrich; Frette, Vidar (Peer reviewed; Journal article, 2021)
      Biomass fuels in large storage units are prone to self-heating and ignition causing smoldering fires. Here, the susceptibility of such ignition processes to parameters is explored through small-scale experiments. In a silo ...
