  • Exploring MultiPath TCP Through Discrete Event Simulation 

    Hexeberg, Henrik Libeck (Master thesis, 2021-06-01)
    Global internet usage is rapidly becoming more mobile. Devices are, as a consequence, equipped with multiple network interfaces to meet the demand for mobility. With the emergence of 5G-technology, this trend will most ...
  • Structural parameterizations of clique coloring 

    Jaffke, Lars; Lima, Paloma T.; Philip, Geevarghese (Journal article; Peer reviewed, 2020)
    A clique coloring of a graph is an assignment of colors to its vertices such that no maximal clique is monochromatic. We initiate the study of structural parameterizations of the Clique Coloring problem which asks whether ...
  • The unsuitable neighbourhood inequalities for the fixed cardinality stable set polytope 

    Lallo Dias, Phillippe Samer; Haugland, Dag (Chapter, 2021)

    For a graph H, a graph G is an H-graph if it is an intersection graph of connected subgraphs of some subdivision of H. H-graphs naturally generalize several important graph classes like interval graphs or circular-arc ...
  • Compressing permutation groups into grammars and polytopes. A graph embedding approach 

    Jaffke, Lars; De Oliveira Oliveira, Mateus; Tiwary, Hans Raj (Journal article; Peer reviewed, 2020)
    It can be shown that each permutation group G ⊑ 𝕊_n can be embedded, in a well defined sense, in a connected graph with O(n+|G|) vertices. Some groups, however, require much fewer vertices. For instance, 𝕊_n itself can ...

    Next-generation sequencing (NGS) is replacing other molecular techniques to become the de facto gene diagnostics approach, transforming the speed of diagnosis for patients and expanding opportunities for precision medicine. ...
  • Visception: An Interactive Visual Framework for Nested Visualization Design 

    Kristiansen, Yngve Sekse; Bruckner, Stefan (Journal article; Peer reviewed, 2020)
    Nesting is the embedding of charts into the marks of another chart. Related to principles such as Tufte’s rule of utilizing micro/macro readings, nested visualizations have been employed to increase information density, ...
  • A Bit-Vector Differential Model for the Modular Addition by a Constant 

    Azimi, Seyyed Arash; Ranea, Adrián; Salmasizadeh, Mahmoud; Mohajeri, Javad; Aref, Mohammad Reza; Rijmen, Vincent Stefaan (Journal article; Peer reviewed, 2020)
    ARX algorithms are a class of symmetric-key algorithms constructed by Addition, Rotation, and XOR, which achieve the best software performances in low-end microcontrollers. To evaluate the resistance of an ARX cipher against ...
  • Transversals of longest paths 

    Cerioli, Marcia R.; Fernandes, Cristina G.; Gómez, Renzo; Gutiérrez, Juan; Lima, Paloma T. (Journal article; Peer reviewed, 2020-03)
    Let lpt(G) be the minimum cardinality of a transversal of longest paths in G, that is, a set of vertices that intersects all longest paths in a graph G. There are several results in the literature bounding the value of ...
  • A Polynomial Kernel for Line Graph Deletion 

    Lochet, William; Eiben, Eduard (Journal article; Peer reviewed, 2020)
    The line graph of a graph G is the graph L(G) whose vertex set is the edge set of G and there is an edge between e,f ∈ E(G) if e and f share an endpoint in G. A graph is called line graph if it is a line graph of some ...
  • Reconstructing ribosomal genes from large scale total RNA meta-transcriptomic data 

    Xue, Yaxin; Lanzén, Anders; Jonassen, Inge (Journal article; Peer reviewed, 2020-03-13)
    Motivation Technological advances in meta-transcriptomics have enabled a deeper understanding of the structure and function of microbial communities. ‘Total RNA’ meta-transcriptomics, sequencing of total reverse transcribed ...
  • Algorithms for the Rainbow Vertex Coloring Problem on Graph Classes 

    Lima, Paloma T.; van Leeuwen, Erik Jan; van der Wegen, Marieke (Journal article; Peer reviewed, 2020)
    Given a vertex-colored graph, we say a path is a rainbow vertex path if all its internal vertices have distinct colors. The graph is rainbow vertex-connected if there is a rainbow vertex path between every pair of its ...
  • A complexity dichotomy for critical values of the b-chromatic number of graphs 

    Lima, Paloma T.; Jaffke, Lars (Journal article; Peer reviewed, 2020)
    A b-coloring of a graph G is a proper coloring of its vertices such that each color class contains a vertex that has at least one neighbor in all the other color classes. The b-Coloring problem asks whether a graph G has ...
  • Reducing Graph Transversals via Edge Contractions 

    Lima, Paloma T.; dos Santos, Vinicius F.; Sau, Ignasi; Souza, Uéverton S. (Journal article; Peer reviewed, 2020)
    For a graph parameter π, the Contraction(π) problem consists in, given a graph G and two positive integers k,d, deciding whether one can contract at most k edges of G to obtain a graph in which π has dropped by at least ...
  • Statistical considerations for the design and interpretation of proteomics experiments 

    Burger, Bram (Doctoral thesis, 2021-06-10)
