  1. 1. Head Injuries in Car-to-Pedestrian Accidents - Investigation of Head Impact Dynamics, Injury Mechanisms and Countermeasures

    University dissertation from Chalmers University of Technology

    Author : Jianfeng Yao; Chalmers tekniska högskola.; Chalmers University of Technology.; [2010]
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Farkostteknik; Vehicle engineering; Pedestrian accident; head injury; injury mechanism; head protection; accident analysis; accident reconstruction; mathematical simulation;

    Abstract : The aim of this study was to investigate head impact dynamics and to establish risk functions for head injuries by mathematical reconstructions of real-world car-to-pedestrian accidents. Furthermore, an attempt was made to develop an approach for the design and evaluation of head-protective devices. READ MORE

  2. 2. Mild head injury Relation to cognition, dementia, fatigue & genetics

    University dissertation from Umeå : Psykologi

    Author : Anna Sundström; Umeå universitet.; [2006]
    Keywords : SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; Neuropsychology; mild head injury; mild brain injury; apolipoprotein E; SOCIAL SCIENCES Social sciences Psychology; SAMHÄLLSVETENSKAP Socialvetenskap Psykologi;

    Abstract : Following a mild head injury (MHI), a person may report a variety of symptoms such as headache, memory disturbance, dizziness, and concentration difficulties. For most persons the symptoms are transient, but some suffer persistent symptoms that can have a major impact on everyday life. READ MORE

    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Road: Components of the vehicle; Road: Components of the vehicle; Neck; Injury; Anthropometric dummy; Severity; Impact test; Rear end collision; Seat; Mathematical model; Velocity; Thesis; Optimization; Mathematical neck models; Rear impact tests; Biomechanics; Teknisk mekanik; Engineering mechanics; BioRID; consumer test; dummy neck; impact severity; low-velocity; mathematical model; neck injuries; rear impact; seat design; whiplash;

    Abstract : The objective of the work underlying this thesis was firstly to develop a neck for a new rear impact dummy, to evaluate the complete dummy and to specify test conditions for a consumer test with attention to AIS 1 neck injuries in rear impacts. In the development of the dummy neck, a mathematical neck model was developed and evaluated. READ MORE

  4. 4. Finite Element Modeling of the Human Head

    University dissertation from Stockholm : KTH

    Author : Svein Kleiven; KTH.; [2002]
    Keywords : Finite element method FEM ; Human head; brain; head injury; epidemiology; statistics; simulations.;

    Abstract : The main objectives of the present thesis were to define the dimension of head injuries in Sweden over a longer period and to present a Finite Element (FE) model of the human head which can be used for preventive strategies in the future. The annual incidence of head injuries in Sweden between 1987 and 2000 was defined at over 22 000, cases most of which were mild head injuries. READ MORE
