• Development of a browser based python IDE for use under exams 

      Fidjestøl, Marcello (Bachelor thesis, 2024)
      Denne bacheloroppgaven utforsker utviklingen av et Python integrert utviklingsmiljø (IDE) tilpasset eksamensformål. Tradisjonelle programmeringsmiljøer følger ofte ikke sikkerhets- og ytelseskravene som er nødvendige for ...
    • On local isometric immersions into complex and quaternionic projective spaces 

      Rivertz, Hans Jakob (Peer reviewed; Journal article, 2011)
      We will prove that if an open subset of CPn is isometrically immersed into CPm, with m < (4/3)n−2/3, then the image is totally geodesic.We will also prove that if an open subset of HPn isometrically immersed into HPm, with ...
    • On those ordinary differential equations that are solved exactly by the improved Euler method 

      Rivertz, Hans Jakob (Journal article; Peer reviewed, 2013)
      As a numerical method for solving ordinary differential equations y'=f(x,y), the improved Euler method is not assumed to give exact solutions. In this paper we classify all cases where this method gives the exact solution ...
    • Spherical sampling methods for the calculation of metamer mismatch volumes 

      Mackiewicz, Michal; Rivertz, Hans Jakob; Finlayson, Graham (Journal article; Peer reviewed, 2019)
      In this paper, we propose two methods of calculating theoretically maximal metamer mismatch volumes. Unlike prior art techniques, our methods do not make any assumptions on the shape of spectra on the boundary of the ...
    • Three dimensional surface preserving smoothing 

      Alsam, Ali; Rivertz, Hans Jakob (Chapter, 2022)
      We propose a new anisotropic diffusion process for removing noise from MRI images without distorting the edges. The method is based on a simple principle: any diffusion that increases a gradient at neighbouring pixels ...
