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

   Kandidat-uppsats, Mälardalens universitet/Utbildningsvetenskap och Matematik

   Författare :Tarek Hasna; [2023]
   Nyckelord :Centrality measures; Degree centrality; Eigenvector centrality; Betweenness centrality; Closeness centrality;

   Sammanfattning : 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.

3. 2. Impact of the autoencoder-based FINTA tractogram filtering method on brain networks in subjects with Mild Cognitive Impairment

   Master-uppsats, KTH/Skolan för kemi, bioteknologi och hälsa (CBH)

   Författare :Teodor Pstrusiński; [2023]
   Nyckelord :Tractography; Autoencoder; diffusion MRI; Filtering; Graph; Connectome; Traktografi; Autoencoder; diffusions MRT; Filtrering; Graf; Konnektom;

   Sammanfattning : Diffusion Magnetic Resonance Imaging (dMRI) is a method for measuring molecular diffusion in biological tissue microstructure. This information can be used to predict the location and orientation of white matter fibers in the brain, a process known as tractography. LÄS MER

4. 3. Strengthening green infrastructure : modelling connectivity between continuity forests with high nature conservation values at the Sveaskog forest holding in northern Sweden

   Master-uppsats, SLU/Dept. of Wildlife, Fish and Environmental Studies

   Författare :Simon Mattsson; [2022]
   Nyckelord :betweenness centrality; connectivity; forest biodiversity; graphab; graph modelling; high conservation value forest; proxy continuity forest; qgis;

   Sammanfattning : The continuity forests of the Swedish boreal landscape have become very sparse due to intensive rotation forestry and human land-use, and the remaining forests are very fragmented. These forests have a high conservational importance as they hold nature values that relies on a long forest continuity. LÄS MER

5. 4. Modelling of Social Networks, Analysis of CommunityStructures and Disease Simulation on Dairy Cattle : The aim of this study is to model a social network of dairy cows, detectcommunities and analyse the influence of these substructures on the spread of acontagious disease. By using this network, the transmission of a contagiousdisease will be simulated through a theoretical simulation function.

   Master-uppsats, Högskolan Dalarna/Institutionen för information och teknik

   Författare :Juliana Macedo; Mira Czarnetzki; [2022]
   Nyckelord :Community Detection Dairy cattle Disease simulation Social Network;

   Sammanfattning : Past research has demonstrated that social networks and community structures have a strong effecton the dynamics of how an infectious disease spreads, although many have focused moreintensively on the impact of the number of connections an individual has. This thesis investigatedhow disease transmission is affected by the social networks’ structures such as communities,centrality measures, cliques, and diameter. LÄS MER

7. 5. Invasive species in Weddell Sea : Effects on food web structure

   Master-uppsats, Linköpings universitet/Institutionen för fysik, kemi och biologi

   Författare :Inger-Marie Wohlfarth; [2020]
   Nyckelord :Centrality; Climate change; Food webs; Google PageRank; Invasive species; Structure; Weddell Sea;

   Sammanfattning : The cold water of Antarctica has a unique endemic fauna, where durophagous predators are rare or absent. Due to climate change the water is heating up and the predators have begun to return to the Southern Ocean, which could bring a lot of changes to the food web. There is a high risk it will lead to losses in the unique marine fauna of Antarctica. LÄS MER
