  1. 16. Computational Modeling, Parameterization, and Evaluation of the Spread of Diseases

    Författare :Robin Marin; Stefan Engblom; Trevelyan J. McKinley; Uppsala universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Parameter estimation; Bayesian modeling; Stochastic epidemiological models; simulation-based inference; approximate bayesian computations; Scientific Computing; Beräkningsvetenskap;

    Sammanfattning : Computer simulations play a vital role in the modeling of infectious diseases. Different modeling regimes fit specific purposes, from ordinary differential equations to probabilistic formulations. LÄS MER

  3. 17. Fundamental studies of non-premixed combustion in turbulent wall jets using direct numerical simulation

    Författare :Zeinab Pouransari; V. Arne Johansson; Christer Fureby; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Turbulence; non-premixed combustion; global reaction; direct numerical simulation; wall-jet; heat release; mixing scales; heat transfer; Other engineering mechanics; Övrig teknisk mekanik;

    Sammanfattning : The present thesis deals with the fundamental aspects of turbulent mixingand non-premixed combustion in wall-jet flows. Direct numerical simulations(DNS) of compressible turbulent flows are performed in a wall-jet configura-tion, which has a close resemblance to many industrial combustion applica-tions. LÄS MER

  4. 18. Numerical simulation of well stirred biochemical reaction networks governed by the master equation

    Författare :Andreas Hellander; Per Lötstedt; Uppsala universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Scientific Computing; Beräkningsvetenskap;

    Sammanfattning : Numerical simulation of stochastic biochemical reaction networks has received much attention in the growing field of computational systems biology. Systems are frequently modeled as a continuous-time discrete space Markov chain, and the governing equation for the probability density of the system is the (chemical) master equation. LÄS MER

  5. 19. Molecular beam study of non-adiabatic electron transfer in the Cl2+Ksurf surface reaction

    Författare :Lars Hellberg; Chalmers tekniska högskola; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; harpooning; electron transfer; Cl2; surface; exo-electrons; sticking; halogen; non-adiabatic; chemiluminescence;

    Sammanfattning : Halogen molecules impinging on alkali metal surfaces constitute model systems for studies of charge transfer, dissociation dynamics and non-adiabatic energy dissipation in molecule-surface reactions. This thesis reports emission of exo-electrons and photons from the surface as a result of strong non-adabaticity in the Cl2 gas on K$^{solid}$ reaction. LÄS MER

  7. 20. Numerical Methods for Stochastic Modeling of Genes and Proteins

    Författare :Paul Sjöberg; Per Lötstedt; Måns Ehrenberg; Achim Schroll; Uppsala universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; master equation; Fokker-Planck equation; stochastic models; biochemical reaction networks; Scientific Computing; Beräkningsvetenskap;

    Sammanfattning : Stochastic models of biochemical reaction networks are used for understanding the properties of molecular regulatory circuits in living cells. The state of the cell is defined by the number of copies of each molecular species in the model. LÄS MER
