  2. 1. Footbridge Dynamics : Human-Structure Interaction

    Author : Emma Zäll; Raid Karoumi; Mahir Ülker-Kaustell; Andreas Andersson; Peter Van den Broeck; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Dynamics; vibration; footbridge; pedestrian bridge; human-structure interaction; runner; running loads; simplified models; Dynamik; vibration; gångbro; människa-bro-interaktion; löpare; löparlaster; förenklade modeller; Civil and Architectural Engineering; Byggvetenskap;

    Abstract : For aesthetic reasons and due to an increased demand for cost-effective and environmentally friendly civil engineering structures, there is a trend in designing light and slender structures. Consequently, many modern footbridges are susceptible to excessive vibrations caused by human-induced loads. READ MORE

  4. 2. Groupthink : An inquiry into the vicissitudes of regressive group processes

    Author : Michael Rosander; Linköpings universitet; []
    Keywords : SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; groupthink; group dynamics; group cohesiveness; group processes; decision-making;

    Abstract : The aim of this thesis was to examine and further develop an expanded groupthink model (Granstrom & Stiwne, 1998), and also to develop methods to capture the phenomenon in ordinary, authentic working groups. The groupthink model was first proposed by Janis (1972, 1982) and incorporates an omnipotent stance as something highly cohesive groups use handle difficult situations. READ MORE

  5. 3. Dynamics in meetings : on leadership and followership in ordinary meetings in different organizations

    Author : Kjell Granström; Karin Aronsson-Ottosson; Per Linell; Linköpings universitet; []
    Keywords : group processes; leadership; followership; decision-making; the school as an organization; SOCIAL SCIENCES; SAMHÄLLSVETENSKAP;

    Abstract : A method for analyzing interactional dynamics in regular meetings and sessions was developed on the basis of Bion's (1961) basic-assumption model. This model postulates that members in groups frequently take part in collective defence activities which prevent the group from carrying out the tasks assigned to them. READ MORE

  6. 4. Polymer and Protein Physics : Simulations of Interactions and Dynamics

    Author : Anna Sinelnikova; Johan Nilsson; Carl Caleman; Erik Lindahl; Uppsala universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; polymers; proteins; Monte Carlo; molecular dynamics; phase diagram; renormalisation group; SPI; polymer effective model; coarse-graining; Physics with specialization in Biophysics; Fysik med inriktning mot biofysik;

    Abstract : Proteins can, without any exaggeration, be called the "building blocks of life". Their physical properties depend not only on the chemical structure but also on their geometric shape. In this thesis, I investigate protein geometry using several different methods.We start with a coarse-graining model to study the general behavior of polymers. READ MORE

  7. 5. Dynamics of biological membranes and associated water

    Author : Peter Berntsen; Chalmers tekniska högskola; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; dielectric spectroscopy; phase transition; glass transition; DSC; lipid bilayers; lipid dynamics; water dynamics; purple membrane; diffusion; polarisation; QENS.; relaxation; long-range conductivity;

    Abstract : An ingenious assembly of biomolecules and water constitute what we call biological tissue. The presence of water in this assembly is fundamental for the physiological processes and can make the difference between life and death. READ MORE
