  4. 12. Mathematical Models of Molecular Evolution

    Author : Martin Nilsson; Chalmers tekniska högskola; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; dynamic fitness landscapes; quasispecies; error thresholds; evolved mutation rates; evolution in dynamic environments;

    Abstract : This thesis deals with mathematical models of Darwinian evolution in populations of simple living organisms. We study models which describe how the representation of different gene sequences in the population is affected by the fundamental forces of evolutionary processes, such as selection pressure, the mutation rate and the time dynamics of the underlying fitness landscape.

  5. 13. Mathematical models of biological interactions

    Author : Linnéa Gyllingberg; David J.T. Sumpter; Kolbjörn Tunström; Uppsala universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Mathematics with specialization in Applied Mathematics; Matematik med inriktning mot tillämpad matematik;

    Abstract : Mathematical models are used to describe and analyse different types of biological interactions.  From self-propelled particle models capturing the collective motion of fish schools to models in mathematical neuroscience describing the interactions between neurons to individual-based models of ecological interactions.

  6. 14. Models for coupled active-passive population dynamics : Mathematical analysis and simulation

    Author : Thi Kim Thoa Thieu; Adrian Muntean; Matteo Colangeli; Grigorios A. Pavliotis; Karlstads universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; pedestrian dynamics; simple exclusion process; Forchheimer flows; Skorohod equations; nonlinear coupling; heterogenous domain; homogenization; drafting; evacuation; Matematik; Mathematics;

    Abstract : In this dissertation, we study models for coupled active--passive pedestrian dynamics from mathematical analysis and simulation perspectives. The general aim is to contribute to a better understanding of complex pedestrian flows. READ MORE

  7. 15. Modelling and inference of relative collision safety in cars

    Author : Anna Vadeby; Linköpings universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Collision; Mathematical model; Head on collision; Injury; Risk; Car; 91 Road: Vehicle design and construction; 91 Road: Vehicle design and construction; 85 Road: Personal injuries; 85 Road: Personal injuries;

    Abstract : We propose a new mathematical model for relative collision safety in cars. Our present research is restricted to head-on crashes between two cars and we try to determine how much of the injury risk in a crash that depends on car model. The relative risks include the driver populations of the different car models. READ MORE
