    • Improving Efficiency in Parameter Estimation Using the Hamiltonian Monte Carlo Algorithm 

      Alfaki, Mohammed (The University of Bergen, 2008)
      This thesis investigates three approaches to improve the performance of the Hamiltonian Monte Carlo algorithm. The first approach enhances the Hamiltonian Monte Carlo by suppressing random walk in the Gibbs sampling using ...

    • Improving Parallel Sparse Matrix-vector Multiplication 

      Tessem, Torbjørn Johnsen (The University of Bergen, 2013-12-19)
      Sparse Matrix-vector Multiplication (SMvM) is a mathematical technique encountered in many programs and computations and is often heavily used. Solving SMvM in parallel allows for bigger instances to be solved, and problems ...

    • The Inclusion Problem for Regular Expressions 

      Hovland, Dag (Springer, 2010)
      This paper presents a new polynomial-time algorithm for the inclusion problem for certain pairs of regular expressions. The algorithm is not based on construction of finite automata, and can therefore be faster than the ...

    • Incompleteness of the Inference System BNeg 

      Golid, Kjetil Midtgarden (The University of Bergen, 2016-05-31)
      Any propositional discourse can be represented as a propositional theory in a specific form in such a way that the theory is inconsistent if and only if the discourse is paradoxical. Propositional theories in this form ...

    • Independent Set on P5-free graphs, an empirical study 

      Haug, Håvard Karim (The University of Bergen, 2015-11-20)
      We implement the recent polynomial time algorithm for the independent set problem on P5-free graphs, and study the performance of this algorithm on graphs of size up to 50. Our empirical results show that the algorithm ...

    • 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 ...

    • Inexact Solution of the Schur Complement Equation in a Primal-Dual Interior-Point Method for Semidefinite Programming 

      Frimannslund, Lennart (The University of Bergen, 2002)
      Master thesis

    • Inferring Required Permissions for Statically Composed Programs 

      Hasu, Tero; Bagge, Anya Helene; Haveraaen, Magne (Springer, 2013)
      Permission-based security models are common in smartphone operating systems. Such models implement access control for sensitive APIs, introducing an additional concern for application developers. It is important for the ...

    • Integral Cryptanalysis 

      Moen, Vebjørn (The University of Bergen, 2002)
      Master thesis

    • Integrated Multi-aspect Visualization of 3D Fluid Flows 

      Brambilla, Andrea; Andreassen, Øyvind; Hauser, Helwig (The Eurographics Association, 2013)
      The motion of a fluid is affected by several intertwined flow aspects. Analyzing one aspect at a time can only yield partial information about the flow behavior. More details can be revealed by studying their interactions. ...

    • Interactive visual analysis of multi-faceted scientific data 

      Kehrer, Johannes (The University of Bergen, 2011-05-27)
      Visualization plays an important role in exploring, analyzing and presenting large and heterogeneous scientific data that arise in many disciplines of medicine, research, engineering, and others. We can see that model ...
      Doctoral thesis

    • Interactive Visual Analysis of Process Data 

      Lampe, Ove Daae (The University of Bergen, 2011-11-30)
      Data gathered from processes, or process data, contains many different aspects that a visualization system should also convey. Aspects such as, temporal coherence, spatial connectivity, streaming data, and the need for ...
      Doctoral thesis

    • Interactive Visual Analysis of Streaming Data 

      Smestad, Geir (Universitetet i Bergen (UiB), 2014-09-23)
      Interactive Visual Analysis (IVA) has proven to be a robust set of methods for visually exploring complex data sets and generating hypotheses from data. Datasets and techniques where the temporal aspect is central has been ...

    • Interactive Visual Analysis of Time-dependent Flows: Physics- and Statistics-based Semantics 

      Pobitzer, Armin (The University of Bergen, 2012-06-22)
      With the increasing use of numerical simulations in the fluid mechanics community in recent years flow visualization increasingly gains importance as an advanced analysis tool for the simulation output. Up to now, ...

    • Interactive Visualization of Streaming Data with Kernel Density Estimation 

      Lampe, Ove Daae; Hauser, Helwig (IEEE, 2011)
      In this paper, we discuss the extension and integration of the statistical concept of Kernel Density Estimation (KDE) in a scatterplotlike visualization for dynamic data at interactive rates. We present a line kernel ...
