  3. 3. Numerical studies of current profile control in the reversed-field pinch

    Author : Jon-Erik Dahlin; Jan Scheffel; Roberto Paccagnella; KTH; []
    Keywords : NATURAL SCIENCES; NATURVETENSKAP; NATURVETENSKAP; NATURAL SCIENCES; Reversed-Field Pinch; RFP; Current Profile Control; CPC; DEBS; DEBSP; active control; feedback; MHD.; Fusion; Fusion;

    Abstract : The Reversed-Field Pinch (RFP) is one of the major alternatives for realizing energy production from thermonuclear fusion. Compared to alternative configurations (such as the tokamak and the stellarator) it has some advantages that suggest that an RFP reactor may be more economic. READ MORE

  4. 4. Multicomponent superconductivity : Vortex matter and phase transitions

    Author : Johan Carlström; Egor Babaev; Leo Radzihovsky; KTH; []
    Keywords : NATURAL SCIENCES; NATURVETENSKAP; Superconductivity; Ginzburg Landau; field theory; Iron pnictide;

    Abstract : The topic of this thesis is vortex-physics in multi component Ginzburg- Landau models. These models describe a newly discovered class of super- conductors with multiple superconducting gaps, and possess many properties that set them apart from single component models. READ MORE

  5. 5. Brain morphology and behaviour in the guppy (Poecilia reticulata) : Effects of plasticity and mosaic brain evolution

    Author : Stephanie Fong; Niclas Kolm; Björn Rogell; Stephen Montgomery; Stockholms universitet; []
    Keywords : NATURAL SCIENCES; NATURVETENSKAP; NATURVETENSKAP; NATURAL SCIENCES; brain plasticity; cognition; reversal learning; spatial learning; directed selection; mosaic brain; heritability; brain morphology; boldness; relative telencephalon size; inhibitory control; detour task; Poecilia reticulata; etologi; Ethology;

    Abstract : Understanding how brains have evolved and subsequently culminated in the huge variation in brain morphology among contemporary vertebrate species has fascinated researchers for many decades. It has been recognized that brain morphology is both genetically and environmentally determined. READ MORE
