    Sammanfattning : Popular Abstract in Swedish Cancer i levern kan vara av två typer - antingen kan den ha sitt ursprung från levern och kallas primär levercancer eller också är den en spridning av tumör till levern från en annan plats i kroppen, s k dottersvulst eller metastas. Idag är kirurgi av tumörer i levern förstahandsbehandling, men tyvärr är det bara 1/10 patienter som har tumör i levern som kan bli aktuella för kirurgisk behandling, s k resektion. LÄS MER

    Sammanfattning : This thesis concerns the prediction of the fluid mechanical conditions in some specific large vessels in the human body. Large vessels are special in the way that the Reynolds number is relatively high and in the case of arteries the flow is pulsatile. LÄS MER

  4. 4. Additively Manufactured Inconel 718 Microstructures and Mechanical Properties

    Detta är en avhandling från Linköping : Linköping University Electronic Press

    Författare :Dunyong Deng; Linköpings universitet.; Linköpings universitet.; [2018]
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

    Sammanfattning : Additive manufacturing (AM), also known as 3D printing, has gained significant interest in aerospace, energy, automotive and medical industries due to its capabilities of manufacturing components that are either prohibitively costly or impossible to manufacture by conventional processes. Among the various additive manufacturing processes for metallic components, electron beam melting (EBM) and selective laser melting (SLM) are two of the most widely used powder bed based processes, and have shown great potential for manufacturing high-end critical components, such as turbine blades and customized medical implants.

  5. 5. On the Microstructures and Anisotropic Mechanical Behaviours of Additively Manufactured IN718

    Detta är en avhandling från Linköping : Linköping University Electronic Press

    Författare :Dunyong Deng; Linköpings universitet.; Linköpings universitet.; [2019]
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

    Sammanfattning : Additive manufacturing (AM), also known as 3D printing, offers great design flexibility for manufacturing components with complex geometries, and has attracted significant interest in the aero and energy industries in the past decades. Among the commercial AM processes, selective laser melting (SLM) and electron beam melting (EBM) are the two most widely used ones for metallic materials. LÄS MER
