  2. 16. Phase field modeling of precipitation reactions in miscibility gap systems

    Author : Deepjyoti Mukherjee; Joakim Odqvist; Henrik Larsson; Benoît Appolaire; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Precipitation; Discontinuous; Diffusion; Boundary; Phase-field; Miscibility-gap; Cemented carbides; Binary alloys; Materials Science and Engineering; Teknisk materialvetenskap;

    Abstract : As a backbone to the cutting tools and rock drilling industry, cemented carbides have been used widely due to their high hardness and wear resistance. Most commercially used cemented carbides contain a hard phase made of Tungsten carbide (WC) and a binder phase which is generally ductile. READ MORE

  4. 17. Towards an improved understanding of precipitation variations over the Tibetan Plateau

    Author : Hui-Wen Lai; Göteborgs universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Third Pole; Tibetan Plateau; precipitation; Asian summer monsoon; westerly jets; Regional Climate Model; satellite observation;

    Abstract : The Tibetan Plateau (TP) and surrounding regions are known as the ``Third Pole'' because of their polar-like environment and large reservoirs of fresh water. Due to the latter aspect, the TP is also considered the ``Water Tower of Asia'', providing essential water resources to the surrounding regions. READ MORE

  5. 18. On the representation of precipitation in high-resolution regional climate models

    Author : Petter Lind; Erik Kjellström; Michael Tjernström; Jan Erik Haugen; Anna Rutgersson; Abdel Hannachi; Stockholms universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Regional climate modeling; high-resolution; convection parameterization; precipitation; extremes; statistical analysis; atmosfärvetenskap och oceanografi; Atmospheric Sciences and Oceanography; meteorologi; Meteorology;

    Abstract : Weather and climate models applied with sufficiently fine mesh grids to enable a large part of atmospheric deep convection to be explicitly resolved have shown a significantly improved representation of local, short-duration and intense precipitation events compared to coarser scale models. In this thesis, two studies are presented aimed at exploring the dependence of horizontal resolution and of parameterization of convection on the simulation of precipitation. READ MORE

  6. 19. Understanding the Role of Molybdenum on the Precipitation in PH Stainless Steels

    Author : MARCUS ANDERSSON; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; silicon; Precipitation; ageing; EFTEM; molybdenum; atom probe.; martensitic PH stainless steel;

    Abstract : The main part of the present work concerns studies of the influence of molybdenum on the microstructure of martensitic PH stainless steels, during ageing at 475°C. A short investigation of the silicon impact has also been conducted. READ MORE

  7. 20. Remote sensing of clouds and precipitation using active and passive microwave observations

    Author : Simon Pfreundschuh; Chalmers tekniska högskola; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Microwave remote sensing; precipitation; clouds; hydrometeors;

    Abstract : Global observations of clouds and precipitation are of great importance for weather prediction and the monitoring of the climate. Nonetheless, the currently available record of global observations does not constrain the properties of clouds very well owing to the inherent limitations of the observation systems used to produce them.
