  2. 1. Quantitative vulnerability analysis of electric power networks

    Author : Åke J. Holmgren; Torbjörn Thedéen; Lars-Göran Mattsson; Terje Aven; KTH; []
    Keywords : Safety Analysis; vulnerability; homeland security; risk analysis; network; electric power system; blackout; power law; statistical analysis; graph theory; branching process; game theory; Säkerhetsanalys; TECHNOLOGY; TEKNIKVETENSKAP;

    Abstract : Disturbances in the supply of electric power can have serious implications for everyday life as well as for national (homeland) security. A power outage can be initiated by natural disasters, adverse weather, technical failures, human errors, sabotage, terrorism, and acts of war. READ MORE

  4. 2. Random geometric graphs and their applications in neuronal modelling

    Author : Fioralba Ajazi; Matematisk statistik; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; random graph; Neural Network; Probability; Inhomogeneous random graph; random distance graph; random grown networks;

    Abstract : Random graph theory is an important tool to study different problems arising from real world.In this thesis we study how to model connections between neurons (nodes) and synaptic connections (edges) in the brain using inhomogeneous random distance graph models. READ MORE

  5. 3. Random graph models and their applications

    Author : Thomas Vallier; Matematisk statistik; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; contact process; phase transition; classical random graphs; degree sequence; preferential attachment; percolation; random graphs;

    Abstract : This thesis explores different models of random graphs. The first part treats a change from the preferential attachment model where the network incorporates new vertices and attach them preferentially to the previous vertices with a large number of connections. READ MORE

    Abstract : Land use change constitutes a primary driving force in shaping social-ecological systems world wide, and its effects reach far beyond the directly impacted areas. Graph based landscape ecological tools have become established as a promising way to efficiently explore and analyze the complex, spatial systems dynamics of ecological networks in physical landscapes.

  7. 5. Random Graphs: Dynamic and Multi-type Extensions

    Author : Sebastian Rosengren; Maria Deijfen; Olle Nerman; Stockholms universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES;

    Abstract : Random graphs is a well-studied field of probability theory, and have proven very useful in a range of applications. However, most random graphs are \textit{static} in the sense that the network structure does not change over time; they also tend to consist of \textit{single-type} objects. This puts restrictions on possible applications. READ MORE
