    • Fast Method for Maximum-Flow Problem with Minimum-Lot Sizes 

      Ganeshan, Vithya (The University of Bergen, 2015-03-03)
      In transportation networks, such as pipeline networks for transporting natural gas, it is often impractical to send across amounts of flow below a certain threshold. Such lower threshold is referred as the minimum-lot size. ...

    • Investigating Streamless Sets 

      Parmann, Erik (Dagstuhl Publishing, 2015)
      In this paper we look at streamless sets, recently investigated by Coquand and Spiwack. A set is streamless if every stream over that set contain a duplicate. It is an open question in constructive mathematics whether the ...

    • Non-Constructivity in Kan Simplicial Sets 

      Bezem, Marc; Coquand, Thierry; Parmann, Erik (Dagstuhl Publishing, 2015)
      We give an analysis of the non-constructivity of the following basic result: if X and Y are simplicial sets and Y has the Kan extension property, then Y X also has the Kan extension property. By means of Kripke countermodels ...

    • Managing spatial selections with contextual snapshots 

      Mindek, Peter; Gröller, Eduard; Bruckner, Stefan (Wiley, 2014-12)
      Spatial selections are a ubiquitous concept in visualization. By localizing particular features, they can be analysed and compared in different views. However, the semantics of such selections often depend on specific ...

    • The index tracking problem with a limit on portfolio size 

      Mutunge, Purity Kamene (The University of Bergen, 2014-11-19)
      For a passive fund manager tracking a benchmark, it is not uncommon to select some, and not all the assets in the index to his portfolio. In this thesis, we consider the problem of minimizing the tracking error under the ...
