1. 1. Identifying Graph Characteristics in Growing Vascular Networks

   University essay from Uppsala universitet/Tillämpad beräkningsvetenskap

   Author : Christopher Finn Plummer; [2024]
   Keywords : Anigogenesis; Vascular Networks; Network Science;

   Abstract : One of the ways that a vascular network grows is through the process of angiogenesis, wherebya new blood vessel forms as a branch from an existing vessel towards an area which isstimulating vascular growth. Due to the demands for nutrients and waste transport, growingtumour cells will access the surrounding vascular network by inducing angiogenesis. READ MORE

3. 2. 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. A Continuous-time ODE Framework to Centrality in Dynamic Networks

   University essay from Lunds universitet/Matematikcentrum; Lunds universitet/Matematik (naturvetenskapliga fakulteten)

   Author : Francisco Garcia Atienza; [2023]
   Keywords : networks; centrality; continuous-time; matrix logarithm; ode framework; katz; resolvent; Mathematics and Statistics;

   Abstract : The present study discusses and evaluates a novel continuous-time approach to network centrality, a fundamental concept in network analysis. Static methods based on discrete snapshots or time slices for measuring node interaction in networks that change over time do not fully capture the dynamical nature of network evolution. READ MORE

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

   University essay from KTH/Skolan för kemi, bioteknologi och hälsa (CBH)

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

   Abstract : 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. READ MORE

6. 5. 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.

   University essay from Högskolan Dalarna/Institutionen för information och teknik

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

   Abstract : 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. READ MORE
