1. 1. Inertial collisions in random flows

   Författare :Kristian Gustafsson; Göteborgs universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Collisions; nonlinear dynamical systems; particles and aerosols; random processes; suspensions; turbulent diffusion; turbulent flows;

   Sammanfattning : In nature, suspensions of small particles in fluids are common. An important example are rain droplets suspended in turbulent clouds. Such clouds can start to rain very quickly and the reason for this is still not fully explained, but it is believed that the turbulent motion in the cloud plays an important role. LÄS MER

3. 2. Energy transfer in collisions between metal clusters and rare gas atoms

   Författare :Jan Westergren; Chalmers tekniska högskola; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; palladium cluster; density of states; heat capasity; caloric equation of states; collisions; energy transfer; MD simulation;

   Sammanfattning : .... LÄS MER

4. 3. On Threat Assessment and Decision-Making for Avoiding Automotive Vehicle Collisions

   Författare :Mattias Brännström; Chalmers tekniska högskola; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; collision avoidance; decision-making; active safety; intersection collisions; rear-end collisions; collision mitigation; threat assessment; autonomous braking; automotive safety;

   Sammanfattning : Road traffic accidents are one of the world’s largest public health problems. In the EU alone, traffic accidents cause approximately 1.8 million injuries and 43.000 fatalities each year. LÄS MER

5. 4. Diffraction in high-energy collisions

   Författare :Christine Rasmussen; Teoretisk partikelfysik - Geonomgår omorganisation; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; QCD; Soft QCD; phenomenology; Diffraction; Multiparton Interactions; Dipole model; Initial state evolution; BFKL evolution.; Fysicumarkivet A:2019:Overgaard;

   Sammanfattning : This thesis concerns itself with low-momentum-transfer processes in high-energy particle collisions. These processes cannot be described in the framework of the fundamental theory of quantum chromodynamics (QCD), but rely on a pre-QCD approach, the Regge theory. LÄS MER
