  1. 1. A Cut Finite Element Method for Partial Differential Equations on Evolving Surfaces

    University essay from KTH/Numerisk analys, NA

    Author : Johan Wärnegård; [2016]
    Keywords : ;

    Abstract : This thesis deals with cut finite element methods (CutFEM) for solving partial differential equations (PDEs) on evolving interfaces. Such PDEs arise for example in the study of insoluble surfactants in multiphase flow. In CutFEM, the interface is embedded in a larger mesh which need not respect the geometry of the interface.

  3. 2. Rotational Diffusion of Cellulose Nanofibrils.

    University essay from KTH/Mekanik

    Author : Johan Wärnegård; William Hedén; [2014]
    Keywords : ;

    Abstract : Cellulose nanofibrils, CNF, is a technical term for the smallest crystalline constituents of wood. Namely particles of cylindrical shape measuring 20-40 nm in diameter and 1-2 um in length. These fibrils display high ultimate tensile strength and a Young's modulus comparable to Kevlar. READ MORE
