  1. 1. Mathematical Simulation of Vehicle-Pedestrian Collisions: Influence of Vehicle Impact Speed and Front-End Structure on the Dynamic Responses of Child and Adult Pedestrians

    Detta är en avhandling från Chalmers University of Technology

    Författare :Xuejun Liu; Chalmers tekniska högskola.; Chalmers University of Technology.; [2003]
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Teknisk mekanik; Engineering mechanics; child pedestrian; mathematical model; scaling method; parametric study; impact speed; vehicle front-end structure; impact biomechanics; safety countermeasure;

    Sammanfattning : The development of effective countermeasures for pedestrian protection requires an understanding of how the impact speed and front-end design of the vehicle influence the injury risks of pedestrians. Because of the high involvement of children in pedestrian accidents, there is also a need for child pedestrian mathematical models. LÄS MER

  2. 2. Injury Biomechanics in Car-Pedestrian Collisions: Development, Validation and Application of Human-Body Mathematical Models

    Detta är en avhandling från Chalmers University of Technology

    Författare :Jikuang Yang; Chalmers tekniska högskola.; Chalmers University of Technology.; [1997]
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Teknisk mekanik; Engineering mechanics; mathematical dynamic model; pedestrian; car; impact biomechanics; safety countermeasure;

    Sammanfattning : The aim of this study was to develop and validate human-body mathematical models which can be used to simulate the dynamic responses of pedestrians in a car impact. The main focus has been on simulations of bumper impact to the lower extremities, since lower extremity injuries most frequently occur in car-pedestrian accidents and result in long-term consequences and high social costs.

  5. 5. Effects of unloading and resistance exercise on skeletal muscle function, size and composition in man : OBS! FEL DATUM ANGIVET TIDIGARE

    Detta är en avhandling från Stockholm : Karolinska Institutet, Department of Physiology and Pharmacology

    Författare :Björn Alkner; Karolinska Institutet.; Karolinska Institutet.; [2005]
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Atrophy; bed rest; confinement; countermeasure; electromyography; human; knee extensors; magnetic resonance imaging; microgravity; muscle function; myosin heavy chains; plantar flexors; resistance exercise; skeletal muscle; spaceflight; strength; training specificity; unloading;

    Sammanfattning : Exposure to microgravity, i.e., spaceflight, causes muscle unloading leading to muscle atrophy and dysfunction. Thus, there is a need for effective countermeasures to combat these effects. LÄS MER
