  1. 1. Influencers in Confinement : Measuring Covid-19’s Impact on Leadership in Pro- Eating Disorder Twitter Communities

    Master-uppsats, Linköpings universitet/Institutet för analytisk sociologi, IAS

    Författare :Jacquelynn Ennis; [2024]
    Nyckelord :Social Network Analysis; Twitter; Pro-eating Disorder; Eating Disorders; Covid-19; Topic Modelling; Online Communities;

    Sammanfattning : The Covid-19 pandemic presented unprecedented challenges, with global lockdowns impacting individuals on a profound scale. Many took to social media to cope with feelings of anxiety and isolation. LÄS MER

  3. 2. An alternative explanation for scale-free speed correlations in starling flocks: coarse-graining in time

    Master-uppsats, Linnéuniversitetet/Institutionen för fysik och elektroteknik (IFE)

    Författare :Mate Jagnjic; [2023]
    Nyckelord :scale-free correlations; active matter; starling flocks; coarse-graining;

    Sammanfattning : In a celebrated series of experimental observations, starling flocks have been shown to be characterized by scale-free, long-ranged spatial correlations in their velocity fluctuations. While this is expected for velocity orientation correlations on the basis of simple symmetry-breaking arguments, the same scaling-free behaviour for speed (i.e. LÄS MER

  4. 3. Storskalig nätverksestimering Utvärdering av en ny metod för glesa nätverk

    Kandidat-uppsats, Göteborgs universitet/Institutionen för matematiska vetenskaper

    Författare :Jenny Andersson; Rebecka Bertilsson; Helena Foogde; Lovisa Köllerström; Robin Lindström; [2019-06-18]
    Nyckelord :;

    Sammanfattning : Partiell korrelation mellan variabler kan implicit erhållas genom precisionsmatrisen. För att estimera denna kan den empiriska kovariansmatrisen inverteras. Problem uppstår när antalet variabler p är större än antalet observationer n, eftersom kovariansmatrisen då får låg rang och inte kan inverteras. LÄS MER

  5. 4. Examining network properties using breadth-first sampling : A case study of the network spanned by the kth.se domain

    Kandidat-uppsats, KTH/Skolan för datavetenskap och kommunikation (CSC)

    Författare :Johannes Westlund; Jakob Svenningsson; [2017]
    Nyckelord :network science; KTH domain; sampling; scale-free; small-world; community structure;

    Sammanfattning : Many real life complex networks consists of a tremendous amount of nodes and edges which make them difficult to extract and analyze. This thesis aims to examine what network prop- erties that can be deduced when considering small samples of a complex network and how well they correspond to the characteristics of the complete network.

  7. 5. Examining the structure of the KTH web

    Kandidat-uppsats, KTH/Skolan för datavetenskap och kommunikation (CSC)

    Författare :Alexander Janson; Snickare Erik; [2016]
    Nyckelord :Netwok science; scale-free; WWW;

    Sammanfattning : This thesis studies the characteristics of the network structure extracted from the public KTH web. The network structure was extracted with a crawler and consisted of 671,013 nodes and 23,515,683 links. LÄS MER
