  2. 6. Radial Basis Function generated Finite Difference Methods for Pricing of Financial Derivatives

    Author : Slobodan Milovanović; Lina von Sydow; Bertram Düring; Uppsala universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Radial basis function; Finite difference; Computational finance; Pricing of financial derivatives; Option pricing; Partial differential equation; Beräkningsvetenskap med inriktning mot numerisk analys; Scientific Computing with specialization in Numerical Analysis;

    Abstract : The purpose of this thesis is to present state of the art in radial basis function generated finite difference (RBF-FD) methods for pricing of financial derivatives. This work provides a detailed overview of RBF-FD properties and challenges that arise when the RBF-FD methods are used in financial applications. READ MORE

  4. 7. Global radial basis function collocation methods for PDEs

    Author : Ulrika Sundin; Elisabeth Larsson; Simon Hubbert; Uppsala universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Scientific Computing; Beräkningsvetenskap;

    Abstract : Radial basis function (RBF) methods are meshfree, i.e., they can operate on unstructured node sets. Because the only geometric information required is the pairwise distance between the node points, these methods are highly flexible with respect to the geometry of the computational domain.

  5. 8. Cardiac surgery and the kidney - studies on the effects of pharmacological interventions on renal perfusion, filtration and oxygenation

    Author : Gudrun Bragadottir; Göteborgs universitet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Kidney failure; acute; glomerular filtration rate; renal circulation; oxygen consumption; cardiac surgery; vasopressin; mannitol; levosimendan; estimating equations;

    Abstract : Acute kidney injury (AKI) commonly complicates cardiac surgery and is associated with high mortality. Renal ischemia is considered to be the major cause. There is a close association between glomerular filtration rate (GFR), tubular sodium reabsorption and renal oxygen consumption (RVO2) in humans. READ MORE

  6. 9. High Order Local Radial Basis Function Methods for Atmospheric Flow Simulations

    Author : Erik Lehto; Elisabeth Larsson; Natasha Flyer; Tobin Driscoll; Uppsala universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Radial basis function; meshless method; high order finite difference; atmospheric flow; hyper-viscosity; stable algorithm; Scientific Computing; Beräkningsvetenskap;

    Abstract : Since the introduction of modern computers, numerical methods for atmospheric simulations have routinely been applied for weather prediction, and in the last fifty years, there has been a steady improvement in the accuracy of forecasts. Accurate numerical models of the atmosphere are also becoming more important as researchers rely on global climate simulations to assess and understand the impact of global warming. READ MORE

  7. 10. Prevention and treatment of acute kidney injury after cardiac surgery

    Author : Bengt Redfors; Göteborgs universitet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Kidney failure; acute glomerular filtration rate renal circulation oxygen consumption cardiac surgery mannitol dopamine norepinephrine autoregulation;

    Abstract : Acute kidney injury (AKI) occurs frequently after cardiac surgery and is independently associated with increased mortality. The main cause of AKI in these patients is renal ischemia. READ MORE
