  4. 2. Towards an adaptive solver for high-dimensional PDE problems on clusters of multicore processors

    Author : Magnus Gustafsson; Sverker Holmgren; Uppsala universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Scientific Computing; Beräkningsvetenskap;

    Abstract : Accurate numerical simulation of time-dependent phenomena in many spatial dimensions is a challenging computational task apparent in a vast range of application areas, for instance quantum dynamics, financial mathematics, systems biology and plasma physics. Particularly problematic is that the number of unknowns in the governing equations (the number of grid points) grows exponentially with the number of spatial dimensions introduced, often referred to as the curse of dimensionality.

  5. 3. Adaptive Solvers for High-Dimensional PDE Problems on Clusters of Multicore Processors

    Author : Magnus Grandin; Sverker Holmgren; Michael Thuné; Michael Bader; Uppsala universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; adaptive mesh refinement; anisotropic refinement; exponential integrators; Lanczos algorithm; hybrid parallelization; time-dependent Schrödinger equation; Scientific Computing; Beräkningsvetenskap;

    Abstract : Accurate numerical solution of time-dependent, high-dimensional partial differential equations (PDEs) usually requires efficient numerical techniques and massive-scale parallel computing. In this thesis, we implement and evaluate discretization schemes suited for PDEs of higher dimensionality, focusing on high order of accuracy and low computational cost. READ MORE

  6. 4. Margaret Atwood's Environmentalism : Apocalypse and Satire in the MaddAddam Trilogy

    Author : Marinette Grimbeek; Maria Holmgren Troy; Magnus Ullén; Sylvia Mayer; Örebro universitet; []
    Keywords : HUMANIORA; HUMANITIES; Margaret Atwood; MaddAddam Trilogy; environmentalism; apocalypse; satire; celebrity activism; metalepsis; commodity aesthetics; storytelling; English; Engelska;

    Abstract : This study considers the way in which Margaret Atwood’s post-apocalyptic MaddAddam Trilogy functions as an environmental project. The main focus is on how the three novels, Oryx and Crake (2003), The Year of the Flood (2009), and MaddAddam (2013), simultaneously draw on and destabilise the apocalypticism inherent in so much environmental discourse, primarily through the use of satire.

  7. 5. High Order Finite Difference Methods with Artificial Boundary Treatment in Quantum Dynamics

    Author : Anna Nissen; Gunilla Kreiss; Sverker Holmgren; Magnus Svärd; Uppsala universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Schrödinger equation; finite difference methods; perfectly matched layer; summation-by-parts operators; adaptive discretization; stability; Beräkningsvetenskap med inriktning mot numerisk analys; Scientific Computing with specialization in Numerical Analysis;

    Abstract : The investigation of the dynamics of chemical reactions, both from the theoretical and experimental side, has drawn an increasing interest since Ahmed H. Zewail was awarded the 1999 Nobel Prize in Chemistry for his work on femtochemistry. READ MORE
