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, IASSammanfattning : 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
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)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
3. Storskalig nätverksestimering Utvärdering av en ny metod för glesa nätverk
Kandidat-uppsats, Göteborgs universitet/Institutionen för matematiska vetenskaperSammanfattning : 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
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)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.

5. Examining the structure of the KTH web
Kandidat-uppsats, KTH/Skolan för datavetenskap och kommunikation (CSC)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
