  1. 1. Switched Bond Graphs : Simulation and Analysis

    Författare :Krister Edström; Linköpings universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Bond graphs; Hybrid systems; Modeling; Simulation; Causality; Discontinuities;

    Sammanfattning : In this thesis an approach to modeling and simulation of mode switching systems is investigated. This approach, switched bond graphs, is an extension of the bond graph language in the sense that it allows modeling of mode switching phenomena.The classical bond graph language as well as the switched bond graph language are presented.

  7. 5. Random graph models and their applications

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

    Sammanfattning : 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. LÄS MER
