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

    University dissertation from Uppsala : Acta Universitatis Upsaliensis

    Author : Victor Shcherbakov; Elisabeth Larsson; Grady B. Wright; [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. Basal boundary conditions, stability and verification in glaciological numerical models

    University dissertation from Uppsala : Acta Universitatis Upsaliensis

    Author : Christian Helanow; Peter Jansson; Brian Hanson; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Glaciology; subglacial hydrology; ice sheet modeling; basal boundary conditions; non-linear Stokes flow; naturgeografi; Physical Geography;

    Abstract : To increase our understanding of how ice sheets and glaciers interact with the climate system, numerical models have become an indispensable tool. However, the complexity of these systems and the natural limitation in computational power is reflected in the simplifications of the represented processes and the spatial and temporal resolution of the models.

    Abstract : This thesis presents a palaeoglaciological study aimed to determine the location, geometry and temporal evolution of palaeo-ice streams of the north-easternmost Laurentide Ice Sheet. The work was accomplished through the geomorphological interpretation of satellite imagery over 3. READ MORE

  4. 4. Studies in Glacier Mass Balance Measurement and its errors

    University dissertation from Stockholm : Department of Physical Geography, Stockholm University

    Author : Andrew Mercer; Peter Jansson; Gunhild Rosqvist; Ian Brown; Jonathan Carrivick; [2018]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Glaciology; Mass Balance; Measurement Errors; naturgeografi; Physical Geography;

    Abstract : The study of the surface mass balance of valley glaciers has a long history but one that is dogged by uncertainty and errors, and uncertainty about those errors. These problems are acknowledged by the glaciological community and have been examined and formalised in several publications. READ MORE
