  2. 1. Adaptive Bounding Volume Hierarchies for Efficient Collision Queries

    Author : Thomas Larsson; Björn Lisper; Tomas Akenine-Möller; Stefane Redon; Mälardalens högskola; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Bounding volume hierarchies; Collision detection; Rigid bodies; Deformable models; Data structures; Simulation; Animation; Three-dimensional graphics and realism; Computer science; Datavetenskap; Datavetenskap;

    Abstract : The need for efficient interference detection frequently arises in computer graphics, robotics, virtual prototyping, surgery simulation, computer games, and visualization. To prevent bodies passing directly through each other, the simulation system must be able to track touching or intersecting geometric primitives. READ MORE

  4. 2. A methodology for operations-based safety appraisal of two-lane rural highways : Application in Uganda

    Author : Godfrey Mwesige; Harilaos Koutsopoulos; Basil Psarianos; KTH; []
    Keywords : passing zones; passing rate; collision risk; accepted gap; time-to-collision; passing sight distance; two-lane rural highways; Uganda; Transportvetenskap; Transport Science;

    Abstract : The majority of the road infrastructure in developing countries consists oftwo-lane highways with one lane in each travel direction. Operational efficiency of these highways is derived fromintermittent passing zones where fast vehicles are permitted by design to pass slow vehicles using the opposite traffic lane. READ MORE

  5. 3. Fluorescence Studies of Membranes -- Proteins and Lipids, their Dynamics and Interactions

    Author : Johan Strömqvist; Jerker Widengren; Thorsten Wohland; KTH; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Fluorescence correlation spectroscopy; cytokinesis; collision theory; protein-protein interactions; lipid dynamics; single-molecule experiment; Biological physics; Biologisk fysik;

    Abstract : In this thesis, fluorescence spectroscopy was utilized to probe protein and lipid dynamics and interactions in their native, or close to native, environments. Thereby insight could be gained into the fundamentals of bacterial cell division and the innateimmune system. A particular focus has been devoted to fluorescence fluctuations. READ MORE

  6. 4. On Prism-based Motion Blur and Locking-proof Tetrahedra

    Author : Mads Rönnow; Chalmers tekniska högskola; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; continuous collision detection; locking; GPU; parallel; real time; FEM; motion blur; prism;

    Abstract : Motion blur is an important visual effect in computer graphics for both real-time, interactive, and offline applications. Current methods offer either slow and accurate solutions for offline ray tracing applications, or fast and inaccurate solutions for real-time applications. READ MORE

  7. 5. Ions colliding with Polycyclic Aromatic Hydrocarbons and Fullerenes

    Author : Fabian Seitz; Henning Schmidt; John Tanis; Stockholms universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; fysik; Physics;

    Abstract : In this thesis a series of experiments on collisions between atomic projectile ions at keV energies and target vapors of either isolated molecules or van der Waals clusters is presented and analyzed. The atomic ions are produced in an Electron Cyclotron Resonance (ECR) ion source, accelerated and guided into the target volume. READ MORE
