    • Arctic tipping points 

      Smolkova, Valentina (Master thesis; Mastergradsoppgave, 2015-05-15)
      The Arctic is warming much faster than the entire planet, and this causes severe melting of sea ice. However, the climate of different regions of the Earth is interconnected, and changes in the amount of ice in the Arctic can dramatically affect the climate across the whole planet. Some scientists claim that a possible tipping point is the event of the ice-free Arctic Ocean in summer. Certain ...
    • Tipping points and crises in financial markets 

      Shemyakina, Polina (Master thesis; Mastergradsoppgave, 2015-05-15)
      Electricity spot markets and other financial markets are complex systems, and it is difficult to forecast their behaviour, especially uncontrolled and unmanageable situations, such as power crises and deflation of financial bubbles. An energy crisis is any price rise in the supply of energy resources to an economy. It has undesirable consequences, occasionally irreversible. The most known of these ...

    • Geomorphological study of the rock-slope failure at Adjet, Storfjord, Troms 

      Nopper, Hannah (Master thesis; Mastergradsoppgave, 2015-06-06)
      Norway is known for its steep mountains and many fjords. This landscape provides the potential for large rock-slope failures (RSFs) which, in turn, can cause other catastrophic hazards, e.g. tsunamis. In Troms County, northern Norway, many RSFs are found east and west of the Lyngen peninsula, within an area of discontinuous permafrost. The RSF at Adjet is located southeast of the Lyngen peninsula. ...

    • Simplicial complexes, Demi-matroids, Flag of linear codes and pair of matroids. 

      Zubair, Ali (Master thesis; Mastergradsoppgave, 2015-05-15)
      We first describe linear error-correcting codes, and show how many of their most important properties are determined by their associated matroids . We also introduce the simplicial complex of the independent sets of a matroid. We then proceed to study flags of linear codes, and recall the definition of demi-matroids, and how such demi-matroids associated to flags can describe important properties ...
    • Homological methods applied to theory of codes and matroids 

      Karpova, Anna (Master thesis; Mastergradsoppgave, 2015-05-15)
      In this thesis we first give a survey of linear error-correcting codes, and how many of their most important properties only depend on the matroids derived from their parity check matrices. We also introduce the Stanley-Reisner ring associated to the simplicial complex of the independent sets of a matroid. We then recall in particular how some important properties of linear codes, including their ...
    • Towers of Betti Numbers of Matroids and Weight Distribution of Linear Codes and their Duals 

      Huerga Represa, Violeta (Master thesis; Mastergradsoppgave, 2015-05-15)
      The main notion behind the study of matroids is linear dependence. In this thesis, we give a survey of the concepts and properties of linear error-correcting codes over finite fields being dependent only on the matroids derived from these codes. In particular, the weight distributions of linear codes, and their extensions, over bigger fields are only dependent on the N-graded Betti numbers of these ...
