  1. 1. Collision Avoidance Theory : with Application to Automotive Collision Mitigation

    Författare :Jonas Jansson; Fredrik Gustafsson; Jonas Ekmark; Linköpings universitet; []
    Nyckelord :;

    Sammanfattning : Avoiding collisions is a crucial issue in most transportation systems as well as in many other applications. The task of a collision avoidance system is to track objects of potential collision risk and determine any action to avoid or mitigate a collision. This thesis presents theory for tracking and decision making in collision avoidance systems. LÄS MER

    Sammanfattning : Full deployment of Autonomous Vehicles (AVs) on public roads is challenging for organizations in the automotive domain in terms of developing safety standards and methods while taking legacy assumptions related to having a human driver and increased complexity and complexity handling into account. Specifically, the safety of AVs in the presence of other road users must be guaranteed as far as possible for different traffic scenarios. LÄS MER

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

    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. Kinetic modelling of runaways in plasmas

    Författare :Ola Embréus; Chalmers tekniska högskola; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; runaway; Fokker-Planck equation; tokamak; Boltzmann equation; positrons; bremsstrahlung; plasma; synchrotron radiation;

    Sammanfattning : The phenomenon of runaway occurs in plasmas in the presence of a strong electric field, when the accelerating force overcomes the collisional friction acting on the charged particles moving through the plasma. Electron runaway is observed in both laboratory and space plasmas, and is of great importance in fusion-energy research, where the energetic electrons can damage the plasma-facing components of fusion reactors.
