  1. 1. Multiphase Contamination in Rock Fractures : Fluid Displacement and Interphase Mass Transfer

    Författare :Zhibing Yang; Auli Niemi; Fritjof Fagerlund; Tissa Illangasekare; Insa Neuweiler; Uppsala universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; multiphase flow; dissolution; mass transfer; invasion percolation; immiscible displacement; fractured media; groundwater contamination; non-aqueous phase liquid; curvature; Hydrology; Hydrologi;

    Sammanfattning : Multiphase flow and transport in fractured rock is of importance to many practical and engineering applications. In the field of groundwater hydrology an issue of significant environmental concern is the release of dense non-aqueous phase liquids (DNAPLs) which can cause long-term groundwater contamination in fractured aquifers.

  3. 2. Dualities, Symmetries and Unbroken Phases in String Theory : Probing the Composite Nature of the String

    Författare :Johan Engquist; Joseph Minahan; Charlotte Kristjansen; Uppsala universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Physics; Theoretical Physics; String Theory; M-Theory; Higher Spin Gauge Theory; Super Yang-Mills Theory; Anti-de Sitter Spacetime; Singletons; Massless Higher Spin Gauge Fields; AdS CFT Correspondence; Spin Chains; Semiclassical Strings; Tensionless Limits; Conformal Symmetry; Supersymmetry; Higher Spin Gauge Symmetry; Integrability; Fysik; Physics; Fysik;

    Sammanfattning : The thesis treats aspects of string/M-theory in anti-de Sitter spacetimes and their supersymmetric completions. By applying the AdS/CFT correspondence, as well as models of spin chains and singletons, we try to attain a better understanding of the underlying symmetries and the unbroken phases of string/M-theory.

  4. 3. Reliability prediction at early functional product development stages

    Författare :Jonas Pavasson; Rikard Mäki; Luleå tekniska universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Datorstödd maskinkonstruktion; Computer Aided Design;

    Sammanfattning : A trend among industrial companies is to change business strategies from hardware-oriented to more service-oriented solutions, e.g. functional product business models. Functional products are typically constituted by hardware together with a service support system. LÄS MER

  5. 4. Semi-solid Al-7Si-Mg castings – Microstructure and mechanical properties

    Författare :Jorge Santos; Anders E.W. Jarfors; Arne Dahle; Hongbiao Dong; Jönköping University; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Rheometal™ process; semi-solid casting; aluminium alloys; dissolution; grain refinement; segregation; intermetallic phases; heat treatment; mechanical properties; fatigue properties; Rheometal™ processen; semi-solid gjutgarna; aluminiumlegeringar; upplösning; kornförfining; segregering; intermetalliska faser; värmebehandling; mekaniska egenskaper; utmattningsegenskaper;

    Sammanfattning : The use of lightweight parts by the vehicle industry produces immediate benefits on the reduction of emissions because less energy is consumed during the production, service, and recycle stages of a product life cycle. Therefore, the development of processes that allow high design freedom for topology optimisation and materials with high specific strength is a great need. LÄS MER

  7. 5. Platformization : Co-Designing Digital Platforms in Practice

    Författare :Anna Sigridur Islind; Ulrika Lundh Snis; Lena Pareto; Benjamin David Eaton; Högskolan Väst; []
    Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; Platforms; Platformization; Co-design; Practice-based platforms; Healthcare; Care sector; Home care; Cancer rehabilitation; Nascent phases of platformization; Action research; Boundary resources; Boundary objects; Boundary practice; Platformization principles; Plattformar; Plattformisering; Co-design; Praktikplattformar; hälso- och sjukvård; Hemtjänst; Cancer rehabilitering; Tidiga faser av plattformisering; Aktionsforskning; Gränsresurser; Gränsobjekt; Gränspraktik; Plattformiseringsprinciper; Work Integrated Learning; Arbetsintegrerat lärande; Informatik; Informatics;

    Sammanfattning : Digital platforms are slowly becoming an important part of both research and everyday work. However, much of the research focus has been on platforms that are already established. Little focus has been on platformization (i.e. LÄS MER
