  2. 1. Adaptive time-integration for goal-oriented and coupled problems

    Author : Peter Meisrimel; Numerisk analys; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; time-adaptivity; goal-oriented problems; error estimation; coupled problems; waveform relaxation; asynchronous methods; conjugate heat transfer;

    Abstract : We consider efficient methods for the partitioned time-integration of multiphysics problems, which commonly exhibit a multiscale behavior, requiring independent time-grids. Examples are fluid structure interaction in e.g., the simulation of blood-flow or cooling of rocket engines, or ocean-atmosphere-vegetation interaction. READ MORE

  4. 2. Strategic raw material supply for the particleboard-producing industry in Europe : Problems and challenges

    Author : Johann Trischler; Johan Bergh; Rupert Wimmer; Linnéuniversitetet; []
    Keywords : LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Biomass production; Lignocellulosic raw material; Non-wood plants; Particleboard; Pulp and paper; Recycling; Thermal energy recovery; Wood plants; Forestry and Wood Technology; Skog och träteknik;

    Abstract : Particleboard was invented to increase the utilization of wood and it soon became an important core material for furniture production. Nowadays, other industries such as the pulp and papermaking industry and the thermal energy recovery industry claim the same type of raw material. READ MORE

  5. 3. Computational Techniques for Coupled Flow-Transport Problems

    Author : Martin Kronbichler; Gunilla Kreiss; Jean-Luc Guermond; Uppsala universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Finite element method; saddle point systems; two-phase flow; level set method; phase field method; stabilization; contact line dynamics; Beräkningsvetenskap med inriktning mot numerisk analys; Scientific Computing with specialization in Numerical Analysis;

    Abstract : This thesis presents numerical techniques for solving problems of incompressible flow coupled to scalar transport equations using finite element discretizations in space. The two applications considered in this thesis are multi-phase flow, modeled by level set or phase field methods, and planetary mantle convection based on the Boussinesq approximation. READ MORE

  6. 4. Surface Modified Capillaries in Capillary Electrophoresis Coupled to Mass Spectrometry : Method Development and Exploration of the Potential of Capillary Electrophoresis as a Proteomic Tool

    Author : Aida Zuberovic; Jonas Bergquist; Ziad El Rassi; Uppsala universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Topology optimization; Design optimization; Material distribution; Wave propagation problems; Inverse problems; Acoustic devices; Medical microwave tomography; High performance computing; Analytical chemistry; Analytisk kemi;

    Abstract : The increased knowledge about the complexity of the physiological processes increases the demand on the analytical techniques employed to explore them. A comprehensive analysis of the entire sample content is today the most common approach to investigate the molecular interplay behind a physiological deviation. READ MORE

  7. 5. Seaweed in the tropical seascape : Importance, problems and potential

    Author : Stina Tano; Christina Halling; Sofia Wikström; Stockholms universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Seaweed; Macroalgae; Eucheumoids; Non-indigenous; Haplotype; Fish; Nursery; Epifauna; Diversity; Seaweed farming; Zanzibar; East Africa; Tropical; marin ekotoxikologi; Marine Ecotoxicology;

    Abstract : The increasing demand for seaweed extracts has led to the introduction of non-native seaweeds for farming purposes in many tropical regions. Such intentional introductions can lead to spread of non-native seaweeds from farming areas, which can become established in and alter the dynamics of the recipient ecosystems. READ MORE
