  2. 16. Measurement of Tumor Extent and Effects of Breast Compression in Digital Mammography and Breast Tomosynthesis

    Author : Daniel Förnvik; Malmö Medicinsk strålningsfysik; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; digital mammography; breast tomosynthesis; breast compression; pressure distribution; breast cancer; circulating tumor cell;

    Abstract : Breast cancer is the most common form of cancer affecting women in the western countries. Today x-ray digital mammography (DM) of the breast is commonly used for early detection of breast cancer. However, the sensitivity of mammography is limited, mainly due to the fact that a 3D volume is projected down to a 2D image. READ MORE

  4. 17. The Jovian Plasma Dynamics and Composition Analyzer (JDC) for ESA's JUICE Mission

    Author : Philipp Wittmann; Martin Wieser; Stas Barabash; Krister Wiklund; Frédéric Allegrini; Umeå universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; JUICE mission; positive ions; negative ions; electrons; time-of-flight; time-of-arrival; PEP; JDC; CEM; channel electron multiplier; pressure; instrument development; calibration; TOF; TOA; fysik; Physics; rymd- och plasmafysik; Space and Plasma Physics;

    Abstract : This dissertation covers the development and calibration of the Jovian plasma Dynamics and Composition analyzer (JDC). JDC is together with five other sensors a part of the Particle Environment Package (PEP), one of the payloads of the European Space Agency's JUpiter ICy moons Explorer (JUICE) mission. READ MORE

  5. 18. Effects of deep excavations in soft clay on the immediate sourroundings-Analysis of the possibility to predict deformations and reactions against the retaining system

    Author : Anders Kullingsjö; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; MIT-S1; Sheet pile wall; Soil-structure interaction; Strain; Stress; Ground surface settlement; Finite element method; Case history; Shear test; Shear strength; Pore pressure; Analysis; Constitutive models; Plane strain; Elastoplasticity; Laboratory tests; Factor of safety; Stiffness; e-ADP; Earth pressure; Anisotropy; Soft Clay; Deep excavation; Retaining wall; Shear stress; Deformation;

    Abstract : When excavating in an urban environment, the evaluation of the magnitude and distribution of ground movements is an important part of the design process, since excessive movements can damage adjacent buildings and utilities. In order to minimize movement of the surrounding soil, a retaining wall support system is used for deep excavations to provide lateral support. READ MORE

  6. 19. Mechanical modelling of blade forming and drainage of flocculated suspensions

    Author : Claes Holmqvist; Anders Dahlkild; Douglas Bousfield; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Applied mechanics; blade forming; pressure distribution; interaction; suction; drainage; Teknisk mekanik; Engineering mechanics; Teknisk mekanik;

    Abstract : A method has been developed for flexible modelling of multi-component twin-wire blade formers. Features such as suction devices, loadable blades, curved blades, and partial contact between the blades and the forming fabrics are easily incorporated. READ MORE

  7. 20. Ventilation System Design - A Fluid Dynamical Study with Focus on Demand Control

    Author : Andreas Karlsson; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; variable airflows; pressure level; ventilation system design; HVAC design; variable air volume; pressure loss; VAV; demand control ventilation;

    Abstract : Ventilation corresponds to a large part of the total energy use of a building and a lot of attention has been paid to how to reduce this energy use. However, much of this work on saving energy has been focused on reduction of the airflows and how this in turn reduces the energy use. READ MORE
