  2. 21. Total Energy Calculations for Predictive Modeling of Crystalline Materials Strength

    Author : Jan Hartford; Chalmers tekniska högskola; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES;

    Abstract : Materials properties depend on phenomena in a hierarchical order from atomic to macroscopic scales. This thesis studies possibilities for electron-structure and total-energy calculations to provide results that are valuable for the modeling of crystalline materials strength. READ MORE

  4. 22. Phase-field modeling of surface-energy driven processes

    Author : Klara Asp Grönhagen; John Ågren; Suzana Fries; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Phase-field method; surface energy; solute drag; solid-state sintering; multicomponent multiphase flow; wetting; liquid-phase sintering; spinodal decomposition; CALPHAD; Materials science; Teknisk materialvetenskap;

    Abstract : Surface energy plays a major role in many phenomena that are important in technological and industrial processes, for example in wetting, grain growth and sintering. In this thesis, such surface-energy driven processes are studied by means of the phase-field method. READ MORE

  5. 23. Sea Ice and Ocean Environmental Applications of Spaceborn SAR

    Author : Sverre Thune Dokken; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Radarsat; SSM I; ERS-1 2; ocean applications; sea ice applications; numerical models; SAR; Arctic Ocean; Envisat; climate change;

    Abstract : The worldwide focus on our changing environment has led to an increased need to observe and characterise a range of environmental phenomena. The Arctic Ocean is particularly sensitive to climate variations. READ MORE

  6. 24. Wind and atmospheric stability characteristics over the Baltic Sea

    Author : Nina Svensson; Erik Sahlée; Hans Bergström; Anna Rutgersson; Xiaoli Guo Larsén; Uppsala universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; coastal transition; stable conditions; boundary layer rolls; low level jet; WRF; Baltic Sea; Meteorology; Meteorologi;

    Abstract : In recent years there has been an increase in offshore wind energy, which poses the need for accurate wind speed estimates in the marine environment, especially in coastal areas where most wind turbines will be placed. This thesis is focused on the Baltic Sea, which is a small, semi-enclosed sea where land-sea interaction play an important role in explaining the wind patterns. READ MORE

  7. 25. The self-spreading double bilayer/Advances in lipid membrane nanotechnology

    Author : Irep Gözen; Chalmers tekniska högskola; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; nanotechnology; pore; lipid double bilayer; rupture; crackling noise; tension; self-spreading; vesicle; flat giant unilamellar vesicle; viscous fingering.;

    Abstract : In my thesis I describe the generation, characterization and uses of self-spreading double bilayers. This new type of solid-supported model membrane combines features and properties of the 2D lipid bilayer membrane, and the 3D phospholiposome. The double bilayer membrane, i.e. READ MORE
