  2. 21. Space in the Space : Designing Sound Environments for the Shared Indoor Workspace

    Author : Martin Ljungdahl Eriksson; Lena Pareto; Davide Rocchesso; Högskolan Väst; []
    Keywords : SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Sound Environment Design; 4E Cognition; Research through Design; Design program; Sound Users; Ljudmiljö; utformning; arbetsplats; medarbetare; Work Integrated Learning; Arbetsintegrerat lärande;

    Abstract : The sound environment in shared indoor workspaces emerges through the interplay of physical layout, materials, technology, and social dynamics. These spaces are designed with specific purposes in mind, taking acoustics into account during construction. READ MORE

  4. 22. Diving Deep into Saturn's Equatorial Ionosphere with Cassini : Insights from the Grand Finale

    Author : Joshua Dreyer; Erik Vigren; Michiko Morooka; Jan-Erik Wahlund; Ingo Müller-Wodarg; Uppsala universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Saturn; Cassini; Grand Finale; Ionosphere; Photochemistry; Planetary Rings; Planetary Science; Space Plasma; Space Physics; Fysik med inriktning mot rymd- och plasmafysik; Physics with specialization in Space and Plasma Physics;

    Abstract : In the summer of 2017, the Cassini mission concluded its nearly 13 years orbiting Saturn with a series of daring dives between the rings and the upper reaches of Saturn's atmosphere. This last phase of the mission, called the Grand Finale, revealed a highly variable equatorial ionosphere dominated by a large influx of ring material from Saturn's D ring. READ MORE

  5. 23. Solitary waves and enhanced incoherent scatter ion lines

    Author : Jonas Ekeberg; Lars Eliasson; Kristof Stasiewicz; Jan Trulsen; Umeå universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; plasma waves and instabilities; nonlinear phenomena; solitons and solitary waves; ionosphere; Sun: corona; incoherent scatter radar; MHD; plasmavågor och instabiliteter; ickelinjära fenomen; solitoner och solitära vågor; jonosfär; solen: korona; inkoherent spridningsradar; MHD; Geocosmophysics and plasma physics; Geokosmofysik och plasmafysik; Space physics; Rymdfysik; Plasma physics; Plasmafysik; Non-linear dynamics; chaos; Icke-linjär dynamik; kaos; fysik; Physics; rymd- och plasmafysik; Space and Plasma Physics;

    Abstract : This thesis addresses solitary waves and their significance for auroral particle acceleration, coronal heating and incoherent scatter radar spectra. Solitary waves are formed due to a balance of nonlinear and dispersive effects. READ MORE

  6. 24. Quantum dynamical effects in complex chemical systems

    Author : S. Karl-Mikael Svensson; Göteborgs universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Quantum dynamics; Radiative association; Classical Wigner method; Feynman path integral; Reaction rate constants; Wigner phase space;

    Abstract : When using mathematical models to computationally investigate a chemical system it is important that the methods used are accurate enough to account for the relevant properties of the system and at the same time simple enough to be computationally affordable. This thesis presents research that so far has resulted in three published papers and one unpublished manuscript. READ MORE

  7. 25. Nonlinear dynamics of frequency sweeping energetic particle modes in tokamaks

    Author : Frida Eriksson; Chalmers tekniska högskola; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; wave-particle interaction; Fusion plasma physics; bump-on-tail; toroidal Alfvén eigenmode; holes and clumps;

    Abstract : In a burning plasma, such as the next generation tokamak experiment ITER, significant numbers of highly energetic particles will be produced via nuclear reactions. The presence of energetic particles, be it fusion born alpha particles or ions accelerated by auxiliary heating schemes, may excite kinetic instabilities and thereby affect the heating and transport of all particles in the plasma.
