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

    Författare :Jianfeng Yao; Chalmers University of Technology; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; accident analysis; head injury; head protection; mathematical simulation; accident reconstruction; injury mechanism; Pedestrian accident;

    Sammanfattning : 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. LÄS MER

  2. 2. Numerical Accident Reconstructions : A Biomechanical Tool to Understand and Prevent Head Injuries

    Författare :Madelen Fahlstedt; Svein Kleiven; Peter Halldin; Michael Gilchrist; KTH; []
    Nyckelord :MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; Head injuries; Accident Reconstruction; Finite element analysis; Injury prevention; Helmet; Cyclist; Pedestrian; Epidemiology; Applied Medical Technology; Tillämpad medicinsk teknik;

    Sammanfattning : Traumatic brain injuries (TBIs) are a major health and socioeconomic problem throughout the world, with an estimated 10 million deaths and instances of hospitalization annually. Numerical methods such as finite element (FE) methods can be used to study head injuries and optimize the protection, which can lead to a decrease in the number of injuries. LÄS MER

  3. 3. Assessment of mobile radiometry data in radiological emergencies using Bayesian statistical methods

    Författare :Antanas Bukartas; Malmö Medicinsk strålningsfysik; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Mobile gamma spectrometry; Gamma spectrometry; Orphan source; lost source; Ionizing radiation; Bayesian; Activity; position; activity density; reconstruction; UAV; car-borne;

    Sammanfattning : Nuclear technology and the use of radiation sources have been extensively adopted in the modern world. Despite that, a number of radiological accidents, significantly affecting population and the environment, has happened. Few of the most known are accidents in Chernobyl and Fukushima nuclear power plants. LÄS MER
