    Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Epidemics; Reproduction number; Final size; Large outbreak; Weighted network; Undirected; Partially directed; Configuration model; Copula; Mathematical Statistics; matematisk statistik;

    Abstract : Networks, consisting of nodes and of edges, can be used to model numerous phenomena, e.g, web pages linking to each other or interactions between people in a population. READ MORE

  4. 2. Epidemics with heterogeneous mixing : stochastic models and statistical tests

  5. 3. Stochastic epidemics on random networks and competition in growth

    Author : Carolina Fransson; Pieter Trapman; Daniel Ahlberg; Julia Komjathy; Stockholms universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; random graphs; branching processes; SIR epidemics; malthusian parameter; urn model; matematisk statistik; Mathematical Statistics;

    Abstract : The COVID-19 pandemic has dramatically demonstrated the importance of epidemic models in understanding and predicting disease spread and in assessing the effectiveness of interventions. The overarching topic of this thesis is stochastic epidemic modelling, with the main focus on the role of the underlying social structure in infectious disease spread. READ MORE

    Keywords : NATURVETENSKAP; NATURAL SCIENCES; SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; complex systems; complex networks; network analysis; empirical networks; air transportation; consumer complaints; information technology; sexual contacts; epidemics; vaccination; Statistical physics; Statistisk fysik; Computational physics; Beräkningsfysik; Technology and social change; Teknik och social förändring; Epidemiology; Epidemiologi; Information technology; Informationsteknik; fysik; Physics; Statistics; statistik; Epidemiology; epidemiologi; Economics; nationalekonomi;

    Abstract : We are constantly struggling to understand how nature works, trying to identify recurrent events and looking for analogies and relations between objects or individuals. Knowing patterns of behavior is powerful and fundamental for survival of any species. READ MORE

  7. 5. Stochastic epidemics on random networks

    Author : Abid Ali Lashari; Pieter Trapman; Filip Lindskog; Peter Neal; Stockholms universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Branching process; Configuration model; Random graph; Epidemic process; Final size; Threshold behaviour; Duration of an epidemic; Vaccination; Mathematical Statistics; matematisk statistik;

    Abstract : This thesis considers stochastic epidemic models for the spread of epidemics in structured populations. The asymptotic behaviour of the models is analysed by using branching process approximations. The thesis contains four manuscripts. READ MORE
