  1. 16. Child Safety in Car Crashes

    Författare :Marianne Johansson; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Numerical modelling; Factorial DOE; Stochastic simulation; Accident reconstruction; MADYMO; Child Safety; Restraint system; Anthropometry; Q3;

    Sammanfattning : Traffic related trauma is the main cause of child fatality and injury in Europe and North America, with the large majority of fatalities and injuries occurring to children in cars. Specifically, head injury is a common outcome in injury causing car accidents. LÄS MER

  3. 17. Observation strategies for current and future geodetic very long baseline interferometry

    Författare :Niko Petteri Kareinen; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; VLBI; automated analysis; Intensives; Earth rotation; VGOS; GGOS;

    Sammanfattning : Geodetic Very Long Baseline Interferometry (VLBI) is an essential technique for space geodesy. It is uniquely capable of simultaneously observing all Earth Orientation Parameters (EOP) and directly giving access to the Earth’s rotation angle (related to Universal Time, UT1). LÄS MER

  4. 18. Modeling and Optimal Control of Heavy-Duty Powertrains

    Författare :Vaheed Nezhadali; Lars Eriksson; Giorgio Rizzoni; Linköpings universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Powertrain; transmission system; optimal control; modeling for control;

    Sammanfattning : Heavy duty powertrains are complex systems with components from various domains, different response times during transient operations and different efficient operating ranges. To ensure efficient transient operation of a powertrain, e.g. LÄS MER

  5. 19. Development and Application of Laser Diagnostics for Studies of Phenomena Related to IC Engine Combustion

    Författare :Greger Juhlin; Förbränningsfysik; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Motors and propulsion systems; framdrivningssystem; Motorer; Laser technology; Laserteknik; Fysicumarkivet A:2003:Juhlin;

    Sammanfattning : Various laser diagnostic techniques have been developed and demonstrated for engine, or engine-related measurements. The experimental work is presented in Chapter 3 and in Papers I-VII. In Chapter 3, imaging of soot in a running compression-ignition (CI) is described. LÄS MER

  7. 20. Interaction between humans and car seats : studies of occupant seat adjustment, posture, position, and real world neck injuries in rear-end impacts

    Författare :Bertil Jonsson; Ulf Björnstig; Mats Svensson; Anders Kullgren; Umeå universitet; []
    Nyckelord :Surgery; backset; Whiplash; rear-end impact; seated posture; seated position; bioRID; Kirurgi; Surgery; kirurgi;

    Sammanfattning : Background: The latest generation of rear-end whiplash protection systems, as found in the WHIPS Volvo and SAHR Saab, have reduced injury rates by almost 50% in comparison with the previous generation of seat/head restraint systems. Occupant behaviour, such as seated posture and seat adjustment settings, may affect the injury risk. LÄS MER
