  2. 6. Developing and evaluating dose calculation models for verification of advanced radiotherapy

    Author : Jörgen Olofsson; Mikael Karlsson; Anders Ahnesjö; Crister Ceberg; Umeå universitet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Radiation therapy; high-energy photons; dose calculation; multi-source model; pencil kernel; uncertainties; action levels; Radiological physics; Radiofysik;

    Abstract : A prerequisite for modern radiotherapy is the ability to accurately determine the absorbed dose (D) that is given to the patient. The subject of this thesis has been to develop and evaluate efficient dose calculation models for high-energy photon beams delivered by linear accelerators. READ MORE

  4. 7. Particle emissions from car brakes : The influence of contact conditions on the pad-to-rotor interface

    Author : Mattia Alemani; Ulf Olofsson; Jens Wahlström; Anders Söderberg; Staffan Jacobson; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Car brakes emissions; transition temperature; working conditions; environmental design; pin-on-disc; Bilbromsutsläpp; övergångstemperatur; arbetsförhållanden; miljödesign; pinne-på-skiva; Machine Design; Maskinkonstruktion;

    Abstract : Due to their adverse health effects emissions have been regulated for over three decades. Brake wear particulate matter is the most important non-exhaust source, however current knowledge is mainly limited to observational studies. READ MORE
