  1. 1. Quantifying Phagocytosis – studies on the antibody response during invasive streptococcal infections

    Författare :Therese de Neergaard; Infektionsmedicin; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Phagocytosis; Hill equation; Streptococcus pyogenes GAS ; Streptococcus dysgalactiae; Antibodies; invasive infection; Phagocytosis; Hill equation; Streptococcus pyogenes; Group A Streptococcus; Streptococcus dysgalactiae; Antibodies; Invasive infection;

    Sammanfattning : The interaction between our immune system and pathogens encompasses a complex spectrum from symbiosis to potentially life-threatening diseases. Throughout evolution, our immune system has evolved numerous strategies such as phagocytosis to combat infections and protect us from diseases. LÄS MER

  3. 2. Aspects of adaptive mesh refinement in the spectral element method

    Författare :Nicolas Offermans; Philipp Schlatter; Ananias Tomboulides; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Error estimators; mesh refinement; adaptivity; spectral element method; algebraic multigrid method; NACA4412; periodic hill case.; Engineering Mechanics; Teknisk mekanik;

    Sammanfattning : This thesis deals with the improvement of the efficiency of numerical simulations in computational fluid dynamics. Some of the limitations of current algorithms on future exascale supercomputers are addressed with the main goal of using adaptive mesh refinement for the simulation of turbulent and three-dimensional flows.

  4. 3. Numerical Simulation of High Reynolds Number Wall Bounded Flow

    Författare :Tobias Persson; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; subgrid model; DES; high; validation; LES; numerical simulation; near-wall;

    Sammanfattning : In this thesis, four different numerical methods are used for predictions of high Reynoldsnumber (Re), wall bounded flows; Large Eddy Simulation (LES) with two different subgrid(turbulence) models, the One Equation Eddy Viscosity model (OEEVM) and the MixedModel (MM), Monotone Integrated LES (MILES), Detached Eddy Simulation (DES) andReynolds Averaged Navier Stokes (RANS). The LES calculations are combined with a wallmodel based on the law-of-the-wall and in DES a hybrid RANS/LES method is used forhandling the near wall region. LÄS MER

  5. 4. Large eddy simulation of cavitating and non-cavitating flow

    Författare :Tobias Huuva; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; high Reynolds number; Cavitation; turbulence; RANS; hydrodynamics; numerical simulation; modelling; DES; LES;

    Sammanfattning : Most marine configurations are subject to a number of complex and important hydrodynamic phenomena affecting the overall performance of the vessel, both regarding resistance and propulsive efficiency. In this thesis, the possibility of numerically simulating some of these phenomena is investigated. LÄS MER

  7. 5. Models of the metabolism of the pancreatic beta-cell

    Författare :Pål Westermark; Anders Lansner; Jean-Pierre Mazat; KTH; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Computer science; Computer science; Datalogi;

    Sammanfattning : The pancreatic β-cell secretes insulin in response to a raised blood glucose level. Deficiencies in this control system are an important part of the etiology of diabetes. LÄS MER
