  1. 1. Comparative Analysis of Adaptive Domain Decomposition Algorithms for a Time-Spectral Method

    University essay from KTH/Skolan för elektroteknik och datavetenskap (EECS)

    Author : Vilhelm Dinevik; [2020]
    Keywords : ;

    Abstract : Time-spectral solvers for partial differential equations (PDE) have been explored in various forms during the last few decades. The generalized weighted residual method (GWRM) is one such method with a high accuracy and efficiency. The GWRM has so far been implemented almost exclusively with a uniform grid of subdomains in the spatial domain. READ MORE

  3. 2. On two-component Bose-Einstein condensates in a ring

    University essay from Lunds universitet/Matematik (naturvetenskapliga fakulteten)

    Author : Marcus Sköld; [2019]
    Keywords : Mathematics and Statistics;

    Abstract : A Bose-Einstein condensate is a type of gas consisting of one or more types of particles called bosons which are cooled to a temperature very close the absolute zero. Under these conditions the particles all start to occupy their lowest quantum state. READ MORE

  4. 3. Pedestrian Evacuation Modelled by a Conservation Law with a Two-inflection-point Flux Function

    University essay from Lunds universitet/Matematik LTH

    Author : Henrik Lindell; [2019]
    Keywords : Numerical analysis; Applied mathematics; Hyperbolic conservation laws; Finite volume methods; Partial differential equations; Pedestrian dynamics; Modeling; Mathematics and Statistics;

    Abstract : When designing a building one must consider safety aspects. One such aspect is that in the case of an emergency people should be able to efficiently evacuate the building. In this paper we investigate how the width-profile of a corridor leading to an exit might affect the efficiency of evacuation. READ MORE

  5. 4. Constant mean curvature surfaces in hyperbolic 3-space

    University essay from Uppsala universitet/Institutionen för fysik och astronomi

    Author : Erik Raab; [2014]
    Keywords : String theory; hyperbolic 3-space; DPW-method;

    Abstract : The aim of this bachelor's thesis has been to investigate surfaces that are the main contributions to scattering amplitudes in a type of string theory. These are constant mean curvature surfaces in hyperbolic 3-space. Classically the way to find such surfaces has been to solve a non-linear partial differential equation. READ MORE

  6. 5. Efficient Quadrature Settings for Elliptic PDE’s using a Coupled FEM and BEM Solver in COMSOL Multiphysics

    University essay from KTH/Numerisk analys, NA

    Author : Gustav Friberg; [2014]
    Keywords : ;

    Abstract : By using singular integral kernels based on the fundamental solution, a partial differential equation (PDE) can be rewritten as a boundary integral defined at the boundary of a domain. This requires a linear differential operator with coefficients that are isotropic and homogeneous in space. READ MORE
