  • Sequences and Linear Codes from Highly Nonlinear Functions 

    Li, Chunlei (The University of Bergen, 2014-06-16)
    Due to optimal nonlinearity and differential uniformity, perfect nonlinear (PN) and almost perfect nonlinear (APN) functions are of great importance in cryptography. It is interesting that they also define optimal objects ...

  • A polynomial-time solvable case for the NP-hard problem Cutwidth 

    Lilleeng, Simen (The University of Bergen, 2014-06-02)
    The Cutwidth problem is a notoriously hard problem, and its complexity is open on several interesting graph classes. Motivated by this fact we investigate the problem on superfragile graphs, a graph class on which the ...

  • Fast methods to solve the pooling problem 

    Kejriwal, Anisha (The University of Bergen, 2014-05-31)
    In pipeline transportation of natural gas, simple network flow problems are replaced by hard ones when bounds on the flow quality are imposed. The sources, typically represented by gas wells, provide flow of unequal ...

  • Linear dependencies between non-uniform distributions in DES 

    Fauskanger, Stian (The University of Bergen, 2014-05-30)
    Davies and Murphy explained some non-uniform distributions of the output from pairs and triplets of S-boxes in DES, and how they are completely dependent on some key bits. There are linear dependencies between these ...

  • Perceptually Uniform Motion Space 

    Birkeland, Åsmund; Turkay, Cagatay; Viola, Ivan (IEEE, 2014-05-07)
    Flow data is often visualized by animated particles inserted into a flow field. The velocity of a particle on the screen is typically linearly scaled by the velocities in the data. However, the perception of velocity ...
