  1. 6. A Novel Immersed-Boundary Method for Multiple Moving and Interacting Bodies

    Författare :Andreas Mark; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; fluid-structure interaction; DNS; immersed-boundary method;

    Sammanfattning : This thesis describes the development, implementation and validation of an implicit, second order accurate, finite-volume and instationary immersed-boundary method for simulating the detailed flow around multiple arbitrary moving and interacting bodies. The potential for flows including moving bodies or boundaries, such as multiphase flows still has to be fully realized. LÄS MER

  3. 7. The Mirroring Immersed Boundary Method - Modeling Fluids with Moving and Interacting Bodies

    Författare :Andreas Mark; Chalmers tekniska högskola; []
    Nyckelord :LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Fiber; DNS; Fluid-structure interaction; Mirroring immersed boundary method;

    Sammanfattning : The detailed fluid flow around arbitrary, moving, interacting and deforming bodies is both complex and poorly understood and the commercial simulation tools simulating such flows are computationally to demanding. Hence, a new fast and accurate method for simulating complex multi-body flows is required. LÄS MER

  4. 8. Increasing uptake of long-acting reversible contraception : LARC

    Författare :Niklas Envall; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :;

    Sammanfattning : BACKGROUND: Unintended pregnancies are an inexhaustible source to life-changing decisions and events for individuals and result in enormous costs for societies having to deal with maternal health services, deliveries, hospital care and abortions. Unmet need of contraception is a contributing factor to unintended pregnancies. LÄS MER

  5. 9. Long-acting reversible contraception (LARC) after pregnancy and childbirth

    Författare :Karin Lichtenstein Liljeblad; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :;

    Sammanfattning : Background and aims: Unmet need of contraception is a global challenge. The need of additional visits to initiate contraception is found to be a barrier for postpartum and postabortion contraceptive care. The IUDs and the implant are called long-acting reversible contraception (LARC). LÄS MER

  7. 10. Reliability-based design of rock tunnel support

    Författare :William Bjureland; Fredrik Johansson; Stefan Larsson; Johan Spross; Lars Rosén; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Rock engineering; reliability-based design; Eurocode 7; observational method; tunnel engineering; Bergmekanik; sannolikhetsbaserad dimensionering; Eurokod 7; observationsmetoden; tunnelbyggnad; Jord- och bergmekanik; Soil and Rock Mechanics;

    Sammanfattning : Since 2009, design of rock tunnels can be performed in accordance with the Eurocodes, which allows that different design methodologies are applied, such as design by calculation or design using the observational method. To account for uncertainties in design, the Eurocode states that design by calculation should primarily be performed using the partial factor method or reliability-based methods. LÄS MER
