  1. 1. Weak Atomic Interactions

    Author : Peter Schef; Sven Mannervik; Juliet C. Pickering; Stockholms universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; metastable states; forbidden transitions; laser probing; hyperfine structure; LRDR; Atomic physics; Atomfysik;

    Abstract : An atom or ion can change quantum state, usually through emission or absorption of a photon. The photon has the same energy as the energy difference between the states of the transition. The states, or energy levels, of an atom are quantized and light emitted, or absorbed, from the atom is therefore of specific wavelengths, giving spectral lines. READ MORE

  2. 2. Insights into weak affinity antibody-antigen interactionsStudies using affinity chromatography and optical biosensor

    Author : Magnus Strandh; Institutionen för immunteknologi; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Bioteknik; Biotechnology; immunosensor; biosensor; weak affinity chromatography; cross-reactivity; antibody-antigen interaction; weak affinity; biomolecular recognition; Immunology; serology; transplantation; Immunologi; serologi;

    Abstract : Molecular recognition and interaction is fundamental for the function of biological systems. The properties of the interacting biomolecules dictate the type of forces involved and the strength and dynamics of the interaction. Many interactions are very strong whereas others exhibit weak affinity. READ MORE

  3. 3. Isospin Breaking in Kaon Decays to Pions

    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Elementary particle physics; termodynamik; statistisk fysik; gravitation; relativitet; kvantmekanik; thermodynamics; Matematisk och allmän teoretisk fysik; Pseudo-scalar meson; Isospin Breaking; Chiral Perturbation Theory; Mathematical and general theoretical physics; classical mechanics; quantum mechanics; relativity; statistical physics; Weak Interaction; Strong Interaction; kvantfältteori; High energy interactions; Kärnfysik; Nuclear physics; klassisk mekanik; quantum field theory; cosmic rays; Kosmisk strålning; högenergi; Elementarpartikelfysik;

    Abstract : The five different K -> 3 Pi and the three K -> 2 Pi decays are calculated in Chiral Perturbation Theory. The calculation is done using different approximations, to study whether this changes the result significantly. First the isospin approximation is used. Discrepancies are then found between theory and experiment. READ MORE

  4. 4. Older People Meet Robots : Three Case Studies on the Domestication of Robots in Everyday Life

    Author : Susanne Frennert; Certec - Rehabiliteringsteknik och Design; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Older people; social robots; gerotranscendence; domestication theory; Participatory Design; social robotics;

    Abstract : This thesis explores how older people construct meaning, use and make sense of three kinds of robots in their homes. The exploration is undertaken in empirical studies of an assistive robot, an eHealth system, and robotic vacuum cleaners. READ MORE

  5. 5. Finite Element Procedures for Fluid-structure Interaction

    Author : Joakim Hermansson; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Nitsche s method; stabilized Crouzeix-Raviart; Winslow s method; Raviart-Thomas; space-time FE; stretched elements; FSI; FEM; weak coupling; mesh smoothing; acoustic FSI; ALE;

    Abstract : This thesis concerns finite element (FE) methods for solving fluid-structure interaction (FSI) problems. Two types of fluid-structure interaction are considered. A finite element method for solving the interaction between a flowing incompressible fluid and a linear elastic structure is proposed. The flow is assumed to be laminar. READ MORE
