  2. 1. Degenerate Geometries, Supersymmetry and Duality

    Author : Henrik Gustafsson; Marcus Grisary; Stockholms universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Physics; fysik;

    Abstract : String theory is a theory attempting to unify gravity with the electro-weak and strong interactions so successfully described by Quantum Field Theory. The implications of String Theory is not fully understood since it is still not a complete theory. READ MORE

  4. 2. Lagrangian Particles in Turbulence and Complex Geometries

    Author : Azad Noorani; Philipp Schlatter; Johan Revstedt; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Direct numerical simulation; wall turbulence; secondary motion; Teknisk mekanik; Engineering Mechanics;

    Abstract : Wall-dominated turbulent dispersed multiphase flows occur in a variety of industrial, biological and environmental applications. The complex nature of the  arrier and the dispersed phase is elevated to a higher level introducing geometrical complexities such as curved walls. READ MORE

  5. 3. Supersymmetric Geometries in Type IIA Supergravity

    Author : Christian von Schultz; Chalmers tekniska högskola; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Flux compactifications; Supergravity; Supersymmetry; Superstring vacua;

    Abstract : Supergravity theory is any supersymmetric theory with a local supersymmetry parameter. This thesis undertakes the study of type IIA supergravity, a supergravity theory in ten dimensions associated with type IIA string theory. READ MORE

  6. 4. Phase Separation and Gelation of Biopolymers in Confined Geometries

    Author : Sophia Wassén; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; gelation; gelatin–maltodextrin; whey protein isolate–gellan gum; structure evolution; confinement; biopolymer mixture; image analysis.; spinodal decomposition; phase separation; confocal laser scanning microscopy; microstructure;

    Abstract : Many biopolymer mixtures exhibit segregative phase separation that generates regions enriched in one polymer and depleted in the other. Today, much is known of how phase separating biopolymer systems behaves in bulk phase, and the final morphology can be controlled and tailored with high precision. READ MORE

  7. 5. Energy Savings by Using Daylight for Basic Urban Shapes : With a Case Study of Three Different Street Types

    Author : Bengt Sundborg; Tigran Haas; Jan Ejhed; Ulf Ranhagen; Barbara Matusiak; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; daylight; energy; climate; urban design principles; urban pattern; street grid; Arkitektur; Architecture;

    Abstract : During winter the sun is in short supply. But research at KTH shows that solar radiation can be facilitated while energy consumption for lighting is reduced. This provided that the buildings are appropriately designed. But, unfortunately, the sunlight is often not taken into account and the results are the opposite. READ MORE
