  3. 7. Improving fatigue properties of welded high strength steels

    Författare :Ebrahim Harati; Lars-Erik Svensson; Leif Karlsson; Norbert Enzinger; Högskolan Väst; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Fatigue strength; Residual stress; Welds; Weld toe geometry; High strength steel; High frequency mechanical impact treatment; Low Transformation Temperature welding consumable; Manufacturing and materials engineering; Produktions- och materialteknik; Production Technology; Produktionsteknik;

    Sammanfattning : In recent years a strong interest has been expressed to produce lighter structures.One possible solution to reduce the weight is to utilize high strength steels and use welding as the joining method. LÄS MER

  4. 8. Sound Generation and Propagation in the Human Upper Airways

    Författare :Lukas Schickhofer; Mihai Mihaescu; Anders Dahlkild; Mats Karlsson; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Engineering Mechanics; Teknisk mekanik;

    Sammanfattning : The human upper airways embrace the source of phonation and affect the modulation of the voice, which is of vital importance for communication. Moreover, unwanted sounds may be generated in the upper airways due to elastic, collapsible parts that are susceptible to flow-induced vibration and resonance. LÄS MER

  5. 9. Surfactant metabolism in the newborn : the impact of ventilation strategy and lung disease

    Författare :Kajsa Bohlin; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :Surface active agents; pulmonary surfactant; respiratory distress syndrome; stable isotope; artificial respiration; continuous positive airway pressure; metabolism; rabbit; compliance; preterm; newborn;

    Sammanfattning : Developmental deficiency in pulmonary surfactant leads to respiratory distress syndrome (RDS) in preterm infants, but all newborns may have impaired surfactant metabolism secondary to lung disease or ventilator induced lung injury. Exogenous surfactant treatment is usually administered in conjunction with mechanical ventilation. LÄS MER

  7. 10. Quantum theory of time-dependent transport in graphene

    Författare :Yevgeniy Korniyenko; Chalmers tekniska högskola; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; graphene; ballistic quantum transport; Landauer-Büttiker theory; Fano resonance; Floquet scattering matrix;

    Sammanfattning : High-quality ballistic electronic devices made from graphene are becoming an experimental reality. Carbon-based electronics is heralded if not to succeed or surpass then to complement the existing semiconducting technology. LÄS MER
