  2. 6. Experimental studies of tearing mode and resistive wall mode dynamics in the reversed field pinch configuration

    Author : Jenny-Ann Malmberg; KTH; []
    Keywords : Nuclear fusion; reversed field pinch; resistive wall instabilities; wall locked modes; tearing modes; resistive shell modes; field errors; Extrap T2; Extrap T2R; TPE-RX;

    Abstract : It is relatively straightforward to establish equilibrium inmagnetically confined plasmas, but the plasma is frequentlysucceptible to a variety of instabilities that are driven bythe free energy in the magnetic field or in the pressuregradient. These unstable modes exhibit effects that affect theparticle, momentum and heat confinement properties of theconfiguration. READ MORE

  5. 8. Holographic descriptions of collective modes in strongly correlated media

    Author : Marcus Tornsö; Chalmers tekniska högskola; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; plasmonics; strongly correlated media; holography; gauge gravity duality; graphene; strong coupling; quasinormal modes;

    Abstract : Solving the puzzle of high temperature superconductivity may be one of the most desired scientific breakthroughs of our time, as access to room temperature superconductivity could revolutionize society as we know it. In this thesis, we strive to increase the theoretical understanding of such matter, by studying the phase above, in temperature, the superconducting phase - the "strange metal". READ MORE

  6. 9. Investigations of Optical Properties and Photo-Alignment in Bistable Nematic Liquid Crystal Displays

    Author : Jesper Osterman; Claes-Göran Granqvist; Kent Skarp; Peter Raynes; Uppsala universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Engineering physics; LCD; liquid crystal; bistable; nematic; optical; modes; photo-alignment; Teknisk fysik; Engineering physics; Teknisk fysik;

    Abstract : In recent years portable electronic devices, such as mobile phones and personal digital assistants, have increased the demand for high performance displays with low power consumption. An interesting candidate with the potential of fulfilling these demands is the reflective single-polarizer surface controlled bistable twisted nematic liquid crystal display. READ MORE

  7. 10. Uncertainty in risk assessment : contents and modes of communication

    Author : Rikard Levin; Sven Ove Hansson; Erik Olsson; KTH; []
    Keywords : HUMANIORA; HUMANITIES; uncertainty; scientific uncertainty; characterization of uncertainty; decision-making under uncertainty; risk assessment; risk management; Philosophy subjects; Filosofiämnen;

    Abstract : Assessments of chemical health risks are performed by scientific experts. Their intended use is as bases for decisions. This thesis tries to answer the questions of how uncertainty is, and should be, communicated in such risk assessments. The thesis consists of two articles and an introductory essay. READ MORE
