  5. 3. On the Finite Element Method for the Time-Dependent Ginzburg-Landau Equations

    Author : Johan Ivarsson; Göteborgs universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; discontinuous Galerkin method; a posteriori error estimate; adaptive finite element method; duality; residual; Ginzburg-Landau equations; superconductivity; residual;

    Abstract : This thesis is primarily concerned with various issues regarding finite element approximation of the time-dependent Ginzburg-Landau equations. The time-dependent Ginzburg-Landau equations is a macroscopic, phenomenological model of superconductivity, consisting of a system of nonlinear, parabolic partial differential equations. READ MORE

  6. 4. Physical Modeling of Brain and Head Kinematics

    Author : Johan Ivarsson; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; brain injury; skull base; rotational acceleration; physical models; lateral ventricles; head kinematics; padding materials; sulci; free motion headform; brain kinematics;

    Abstract : The development of head injury criteria and countermeasures for head protection requires understanding of how different factors affect brain and head kinematics. In this thesis, 2D physical models of the human head were developed and used to evaluate how various factors affect brain kinematics during angular head kinematics. READ MORE

  7. 5. The role of implementation science in healthcare improvement efforts : investigating three complex interventions

    Author : Anna Westerlund; Monica Nyström; Anneli Ivarsson; Rickard Garvare; Eva Eurenius; Johan Thor; Umeå universitet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; healthcare improvement; knowledge-practice gap; implementation science; complex interventions; implementation strategy; change facilitation; case studies; folkhälsa; Public health; hälso- och sjukvårdsforskning; health services research;

    Abstract : For decades, scholars have found significant gaps between the knowledge available and the knowledge applied in healthcare. Many potential benefits of adequate knowledge based interventions are therefore never achieved. A considerable body of knowledge has evolved on how to promote a better uptake of evidence-based knowledge into routine use. READ MORE
