  1. 1. Predictive model of perceived driving stability at high speeds under aerodynamic excitations

    Författare :Arun Kumar; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; driver-vehicle interaction; unsteady aerodynamics; Driving simulator; on-road tests; predictive model; vehicle stability; subjective evaluation;

    Sammanfattning : The automotive industry is continuously advancing towards more energy-efficient vehicle designs.  Streamlined vehicles have low aerodynamic drag but have the potential to be unstable when  exposed to external excitations such as unsteady aerodynamic forces created by the flow of air  around them.

  3. 2. Driving assessment and driving behaviour

    Författare :Helena Selander; Torbjörn Falkmer; Jönköping University; []
    Nyckelord :;

    Sammanfattning : IntroductionDriving is an important part of everyday life and represents independence. Activities, both productive and social, may be affected if a person can no longer drive. Older drivers, as a group, have a low crash rate. LÄS MER

  4. 3. Cerebral complications after cardiac surgery

    Författare :Ewa Ahlgren; Jan van der Linden; Östergötlands Läns Landsting; []
    Nyckelord :MEDICINE; MEDICIN;

    Sammanfattning : Cerebral injuty remains a major cause of morbidity and mortality after cardiac surgery. Previous studies have mainly focused on preoperative risk factors and intraoperative events but cerebral complications may also occur in the postoperative period. LÄS MER

  5. 4. Subjective perception and prediction model of vehicle stability under aerodynamic excitations

    Författare :Arun Kumar; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; human-vehicle interaction; prediction model; drivability; unsteady aerodynamics; Driving simulator; driver perception.; vehicle stability;

    Sammanfattning : The current automotive era is moving towards electrified vehicle propulsion. As a result, an energy efficient vehicle design becomes one of the top priorities. From an aerodynamics point of view, the vehicle should be more streamlined for minimal aerodynamic drag. LÄS MER

  7. 5. Modelling and experimental testing of truck tyre rolling resistance

    Författare :Jukka Hyttinen; Lars Drugge; Jenny Jerrelind; James Busfield; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Truck tyre; PRF; filler-reinforced rubber; ambient temperature; rubber testing; constitutive modelling; parametrisation; rolling resistance; load cell; Fletcher-Gent effect; Payne effect; Lastbilsdäck; PRF; förstärkande fyllmedel; gummi; omgivningstemperatur; gummiprovning; konstitutiv modellering; parametrisering; rullmotstånd; lastcell; Fletcher-Gent effekt; Payne effekt; Teknisk mekanik; Engineering Mechanics;

    Sammanfattning : Truck transport offers a versatile way to ship goods in regional, long haulage and urban applications. However, the heavy truck sector accounts for 6 % of total greenhouse gas emissions in the European Union. Therefore, there is a need for a substantial reduction of these emissions to secure the sustainability of Earth for future generations. LÄS MER
