  4. 3. Tracing pathways in the ocean circulation : A temperature and salinity perspective

    Författare :Sara Berglund; Kristofer Döös; Jonas Nycander; Göran Broström; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Lagrangian trajectories; Climate modelling; Atlantic Ocean; Southern Ocean; Ocean circulation; heat; atmosfärvetenskap och oceanografi; Atmospheric Sciences and Oceanography;

    Sammanfattning : The ocean circulation plays an essential role in our climate system. It redistributes heat, salt, carbon and other tracers across the globe, making the climate of Earth more moderate. This thesis targets density differences that are driving the ocean circulation. These differences are caused by changes in temperature and salinity. LÄS MER

  5. 4. High volumetric machining strategies for superalloy gasturbine components : Comparing conventional and nonconventional machining methods for efficient manufacturing

    Författare :Jonas Holmberg; Johan Berglund; Anders Wretland; Tomas Beno; Joel Andersson; Sten Johansson; RISE; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Alloy 718; High volumetric machining; Conventional and Nonconventional machining; Material removal rate; Post processing; surface integrity; Residual stress; Microstructure; Deformation; Manufacturing; Surface and Joining Technology; Bearbetnings-; yt- och fogningsteknik; Production Technology;

    Sammanfattning : There is a strong industrial driving force to find alternative manufacturing technologies in order to make the production of aero engine components of superalloys even more efficient than it is today. Introducing new and nonconventional machining technologies, as well as enhanced utilisation of today's high volumetric manufacturing, allows taking a leap to increase the material removal rate and the productivity.
