3. 2. Particularly harmful particles? A study of airborne particles with a focus on genotoxicity and oxidative stress

   Författare :Hanna Karlsson; Karolinska Institutet; Karolinska Institutet; []
   Nyckelord :particulate matter; particles; genotoxicity; oxidative stress; DNA damage; inflammation; subway; tire-road; wood;

   Sammanfattning : Today it is well established that particulate matter (PM) cause a wide range of health effects. The underlying mechanisms likely include inflammation, oxidative stress and genotoxicity. There is however a lack of knowledge regarding how particles from different sources contribute to these effects. LÄS MER

4. 3. Autonomous Vehicle Maneuvering at the Limit of Friction

   Författare :Victor Fors; Lars Nielsen; Björn Olofsson; Jan Åslund; Christian Gerdes; Linköpings universitet; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

   Sammanfattning : Without a driver to fall back on, a fully self-driving car needs to be able to handle any situation it can encounter. With the perspective of future safety systems, this research studies autonomous maneuvering at the tire-road friction limit. In these situations, the dynamics is highly nonlinear, and the tire-road parameters are uncertain. LÄS MER

5. 4. Particle Filtering and Optimal Control for Vehicles and Robots

   Författare :Karl Berntorp; Institutionen för reglerteknik; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; particle filtering; optimal control; automotive systems; out-of-sequence measurement; autonomy; model predictive control; sensor fusion; wheel slip; dynamic optimization;

   Sammanfattning : This thesis covers areas within estimation and optimal control of vehicles, in particular four-wheeled vehicles. One topic is how to handle delayed and out-of-sequence measurements (OOSMs) in tracking systems. LÄS MER
