  1. 1. Localised Radial Basis Function Methods for Partial Differential Equations

    University dissertation from Uppsala : Acta Universitatis Upsaliensis

    Author : Victor Shcherbakov; Uppsala universitet.; Uppsala universitet.; [2018]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Radial basis function; Partition of unity; Computational finance; Option pricing; Credit default swap; Glaciology; Fluid dynamics; Non-Newtonian flow; Anisotropic RBF; Beräkningsvetenskap med inriktning mot numerisk analys; Scientific Computing with specialization in Numerical Analysis;

    Abstract : Radial basis function methods exhibit several very attractive properties such as a high order convergence of the approximated solution and flexibility to the domain geometry. However the method in its classical formulation becomes impractical for problems with relatively large numbers of degrees of freedom due to the ill-conditioning and dense structure of coefficient matrix.

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

    University dissertation from Uppsala : Acta Universitatis Upsaliensis

    Author : Erik Lehto; Uppsala universitet.; Uppsala universitet.; [2012]
    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

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

    University dissertation from Uppsala : Acta Universitatis Upsaliensis

    Author : Slobodan Milovanović; Uppsala universitet.; Uppsala universitet.; [2018]
    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. 4. Acute Achilles tendon rupture - The impact of calf muscle performance on function and recovery

    University dissertation from Göteborg : Göteborgs universitet

    Author : Annelie Brorsson; Göteborgs universitet.; Gothenburg University.; [2017]
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Achilles tendon rupture; Rehabilitation; Heel-rise; Function; Recovery; Calf muscle; Ankle biomechanics; Endurance; Jump; Sex differences;

    Abstract : There is an ongoing debate about the optimal treatment for patients with an acute Achilles tendon rupture. The overall purpose of this thesis was to acquire a greater knowledge of the way patients recover at different time points after the injury when treated with the currently recommended treatment protocols.

  5. 5. Stem cell function and organ development analysis of Lhx2 function in hematopoietic stem cells and eye development

    University dissertation from Umeå : Umeå university

    Author : Lina Dahl; Umeå universitet.; [2010]
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Lhx2; hematopoietic system; hematopoietic stem cell; progenitor; embryonic stem cell; embryoid body; eye development; forebrain; eye field transcription factor; MEDICINE Dermatology and venerology; clinical genetics; internal medicine Internal medicine Molecular medicine genetics and pathology ; MEDICIN Dermatologi och venerologi; klinisk genetik; invärtesmedicin Invärtesmedicin Molekylär medicin genetik och patologi ; molekylär medicin genetik och patologi ; Molecular Medicine;

    Abstract : When a multicellular organism suffers damages to tissues/organs it heals itself by either substituting the lost cellular matrix by scar formation or by regenerating the lost tissue. Regeneration likely occurs by a recapitulation of the developmental process that formed the organ. READ MORE
