  1. 1. Exploring the Impact of Centrality Measures on Stock Market Performance in Stockholm Market: A Comparative Study

    University essay from Mälardalens universitet/Utbildningsvetenskap och Matematik

    Author : Tarek Hasna; [2023]
    Keywords : Centrality measures; Degree centrality; Eigenvector centrality; Betweenness centrality; Closeness centrality;

    Abstract : Centrality measures in network analysis have become a popular measurement tool for identifying coherent nodes within a network. In the context of stock markets, the centrality measure helps to identify key performing ele- ments and strengths for specific stocks and determine their impact on disrupting market value and performance.

  4. 3. Hide and Seek in a Social Network

    University essay from Linköpings universitet/Kommunikationssystem

    Author : Olle Abrahamsson; [2017]
    Keywords : terrorists; hiding; network theory; social network; graph theory; eigenvector centrality; game theory; cooperative game; Shapley value; Myerson value;

    Abstract : In this thesis a known heuristic for decreasing a node's centrality scores while maintaining influence, called ROAM, is compared to a modified version specifically designed to decrease eigenvector centrality. The performances of these heuristics are also tested against the Shapley values of a cooperative game played over the considered network, where the game is such that influential nodes receive higher Shapley values.

  5. 4. Computing network centrality measures on fMRI data using fully weighted adjacency matrices

    University essay from Umeå universitet/Institutionen för datavetenskap

    Author : Stefan Bränberg; [2016]
    Keywords : ;

    Abstract : A lot of interesting research is currently being done in the field of neuroscience, a recent subject being the effort to analyse the the human brain connectome and its functional connectivity. One way this is done is by applying graph-theory based network analysis, such as centrality, on data from fMRI measurements. READ MORE
