  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. Development of a Test Environment for Air Intake Aerodynamics of Road Vehicles

    Författare :Lasse Malmkjaer Christoffersen; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; radiator model.; wind tunnel; erodynamics; reynolds effects;

    Sammanfattning : In the past years work on aerodynamics of road vehicles, the focus has mainly been on shaping the exterior. Recently, however, the focus has shifted towards an optimization of details. One such detail is the air intake for the cooling system. LÄS MER

  4. 3. 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

  5. 4. Driving ability among people with stroke : developing assessments and exploring the lived experience

    Författare :Ann-Helen Patomella; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :Occupational therapy; automobile driving; stroke; awareness of disability; rasch; phenomenology;

    Sammanfattning : The overall aim of this thesis was to explore and describe methods for assessing driving ability and awareness of driving disability following stroke, and to explore and describe the lived-experience of driving ability in the process of a driving evaluation. The thesis included four studies. LÄS MER

  7. 5. 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
