      Gulbrandsen, Jonas Holmberg (Master thesis; Mastergradsoppgave, 2017-06-22)
      Fotballstadioner har ved flere anledninger vært utsatt for uønskede hendelser der fravær av sikkerhetskultur har blitt omtalt som en hovedårsak til hvordan hendelsen kunne oppstå. Denne oppgaven undersøker sikkerhetskulturen ved en stor europeisk fotballklubb som spiller på en stadion med en kapasitet på over 35 000 mennesker. På bakgrunn av at flere tusen mennesker er samlet på et lite avgrenset ...
    • Improving mechanical grip on winter tires. Finite element analysis on pressure profile of airless tire compared to conventional tire using ANSYS workbench 

      Ludvigsen, Sondre (Master thesis; Mastergradsoppgave, 2017-06-22)
      The harsh climate of the arctic has always been one of the most difficult areas to drive cars in. The severe loss in traction due to snow and icing on the roads, has led to an increased risk of collisions. The winter tires for cars has developed through the years after their introduction in the 1930’s. There have been three revolutionary changes made since then; implement of studs, changing in tread ...
    • Removal of methane through hydrological, microbial, and geochemical processes in the shallow sediments of pockmarks along eastern Vestnesa Ridge (Svalbard) 

      Hong, Wei-Li; Sauer, Simone; Panieri, Giuliana; Ambrose, William; James, Rachel; Plaza-Faverola, Andreia; Schneider, Andrea (Journal article; Tidsskriftartikkel; Peer reviewed, 2016)
      The recent discovery of methane seeps in the Arctic region requires a better understanding of the fate of methane in marine sediments if we are to understand the contributions of methane to Arctic ecosystems and climate change. To further this goal, we analyze pore water data from five pockmarks along eastern Vestnesa Ridge, a sediment drift northwest of Svalbard, to quantify the consumption ...
    • Structural and metamorphic implications of the final emplacement of the Lyngen Nappe 

      Schiffer, William Joel (Master thesis; Mastergradsoppgave, 2017-06-15)
      The Lyngen Nappe, an allochthonous unit of the Northern Norwegian Caledonides, consists of Greenschist-facies rocks overlying Amphibolite- to Granulite-facies rocks in the Nordmannvik Nappe. The lower-grade metamorphism seen in the Lyngen rocks juxtaposes higher-grade rocks both above and below. The nature and origin of this metamorphic break is investigated, specifically in the sheared rock units ...

    • Almost affine codes and matroids 

      Diachkov, Konstantin (Master thesis; Mastergradsoppgave, 2017-05-15)
      In this thesis we study various types of block codes, like linear, mutlti-linear, almost affine codes. We also look at how these codes can be described by associated matroids. In addition we look at flags (chains) of codes and see how their behavior can be described using demi-matroids. We also introduce weight polynomials for almost affine codes.

Among other things, it addressed the question of the variability in mesosphere/lower thermosphere (MLT) turbulence, both in time and space. A unique feature of the WADIS project was multi-point turbulence sounding applying different measurement techniques including ...
    • A Framework for Mellin Kind Series Expansion Methods 

      Brenn, Torgeir; Anfinsen, Stian Normann (Journal article; Tidsskriftartikkel, 2017-07-31)
      Mellin kind statistics (MKS) is the framework which arises if the Fourier transform is replaced with the Mellin transform when computing the characteristic function from the probability density function. We may then proceed to retrieve logarithmic moments and cumulants, that have important applications in the analysis of heavy-tailed distribution models for nonnegative random variables. In this paper ...

We also introduce a reformulation of the Edgeworth series ...
    • Automated Lung Sound Analysis 

      Grønnesby, Morten (Master thesis; Mastergradsoppgave, 2016-06-01)
      Lungs sounds has been used as a diagnostic tool for centuries. The usefulness of listening to lung sounds, or pulmonary auscultation, as a definite diagnostic method has been diminished by advances in medical imaging such as chest X-Ray, but these advanced methods also bring a higher monetary and time cost. In addition, when the severity of pulmonary conditions changes, audible symptoms change ...
    • What similarities can municipalities experience in crisis management? 

      Nilsen, Aud Solveig (Conference object; Konferansebidrag, 2017-06)
      Municipalities have an important role in crisis management. The Norwegian emergency principles of responsibility, parity and proximity are central, and the government expects municipalities to take care of crises in their area in accordance with the civil protection law. Due to the varying natures of different crises, one can expect crisis management to take different paths. This paper challenges ...
