    • Sammenhenger mellom koder, matroider, grafer og simplisielle komplekser 

      Heiseldal, Bård (The University of Bergen, 2008)
      Denne masteroppgaven handler hovedsakelig om å studere sammenhenger mellom ulike em- ner innen algebra og kombinatorikk. De matematiske konseptene som studeres, er lineære koder, matroider, grafer og simplisielle komplekser, ...

    • Sampling error distribution for the ensemble Kalman filter update step 

      Kovalenko, Andrey; Mannseth, Trond; Nævdal, Geir (Springer, 2011-07-06)
      In recent years, data assimilation techniques have been applied to an increasingly wider specter of problems. Monte Carlo variants of the Kalman filter, in particular, the ensemble Kalman filter (EnKF), have gained ...

    • Scroll codes over curves of higher genus 

      Johnsen, Trygve; Rasmussen, Nils Henry (Springer, 2010)
      We construct linear codes from scrolls over curves of high genus and study the higher support weights di of these codes. We embed the scroll into projective space Pk-1 and calculate bounds for the di by considering the ...

    • Semiparametric model selection for copulas 

      Jordanger, Lars Arne (The University of Bergen, 2013-06-03)
      This thesis will consider the performance of the cross-validation copula information criterion, xv-CIC, in the realm of finite samples. The theory leading to the xv-CIC will be outlined, and an analysis will be conducted ...

    • Sequential Data Assimilation in High Dimensional Nonlinear Systems 

      Stordal, Andreas Størksen (The University of Bergen, 2011-10-21)
      Since its introduction in 1994, the ensemble Kalman filter (EnKF) has gained a lot of attention as a tool for sequential data assimilation in many scientific areas. Due to its computationally fast and easy to implement ...

    • Sequestration of Carbon in Saline Aquifers Mathematical and Numerical Analysis 

      Nordbotten, Jan Martin (The University of Bergen, 2004-04-30)
      The work in this thesis focuses equally on two main topics. The first of these subjects deals with development of criteria for monotonicity of con- trol volume methods. These methods are important and frequently used ...

    • Sigma coordinate pressure gradient errors and the basin problem 

      Ness, Borghild (The University of Bergen, 2010-04-15)
      This work will focus on how the internal pressure gradient errors affect the numerical instability in idealised ocean basins. The nature of the errors will be investigated and discussed. First, in Chapter 1, the ocean model ...

    • Simulating spatial and temporal varying CO2 signals from sources at the seafloor to help designing risk-based monitoring programs 

      Ali, Alfatih Omer Mohammed Ahmed; Frøysa, Håvard G; Avlesen, Helge; Alendal, Guttorm (Wiley, 2016-01)
      Risk-based monitoring requires quantification of the probability of the design to detect the potentially adverse events. A component in designing the monitoring program will be to predict the varying signal caused by an ...

    • Simulations of multi-beam sonar echos from schooling individual fish in a quiet environment 

      Holmin, Arne Johannes; Handegard, Nils Olav; Korneliussen, Rolf J.; Tjøstheim, Dag (Acoustical Society of America, 2012-12)
      A model is developed and demonstrated for simulating echosounder and sonar observations of fish schools with specified shapes and composed of individuals having specified target strengths and behaviors. The model emulates ...

    • Skadebeløpsmodellering i skadeforsikring 

      Holmedal, Hege Kristine Kristvik (The University of Bergen, 2009-06-01)
      I oppgaven modelleres skadegrader for skip med lognormalfordeling og Paretofordeling. I tillegg tar den for seg en ny sammenlått lognormal-Paretofordeling, og tilpasser de samme dataene til denne fordelingen. Skadegradene ...

    • Skipped spawning in Northeast Arctic haddock Melanogrammus aeglefinus 

      Skjæraasen, Jon Egil; Korsbrekke, Knut; Nilsen, Trygve; Fonn, Merete; Kjesbu, Olav Sigurd; Dingsør, Gjert Endre; Nash, Richard David Marriott (Inter-Research, 2015-04-22)
      Large interannual fluctuations in the numbers of offspring joining a teleost population are common, yet factors affecting offspring production, a key driver of fish population size and demography, are often poorly understood. ...

    • Solute transport in aquifers with evolving scale heterogeneity 

      Suciu, Nicolae; Attinger, Sabine; Radu, Adrian Florin; Vamo̧s, Cǎlin; Vanderborght, Jan; Vereecken, Harry; Knabner, Peter (Tipografia Universitatii Ovidius, 2015)
      Transport processes in groundwater systems with spatially heterogeneous properties often exhibit anomalous behavior. Using first-order approximations in velocity fluctuations we show that anomalous superdiffusive behavior ...

    • Solution strategies for nonlinear conservation laws 

      Skogestad, Jan Ole (The University of Bergen, 2015-08-21)
      Nonlinear conservation laws form the basis for models for a wide range of physical phenomena. Finding an optimal strategy for solving these problems can be challenging, and a good strategy for one problem may fail spectacularly ...
