  2. 1. Car-To-Car Side Impacts: Development and Validation of Mathematical Models and their Usability for Protective System Design

    Author : Bengt Pipkorn; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; dummy; injury criteria; padding; mathematical simulations; barrier; side impact; car; occupant; airbag;

    Abstract : The objective of the present work was to develop and use mathematical models to establish principles for protective systems for occupants in car-to-car side impacts. The efforts in this work have concentrated on the protection of the thorax and abdomen since these body parts are most frequently injured in side impacts. READ MORE

  4. 2. Physical Modeling of Brain and Head Kinematics

    Author : Johan Ivarsson; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; brain injury; skull base; rotational acceleration; physical models; lateral ventricles; head kinematics; padding materials; sulci; free motion headform; brain kinematics;

    Abstract : The development of head injury criteria and countermeasures for head protection requires understanding of how different factors affect brain and head kinematics. In this thesis, 2D physical models of the human head were developed and used to evaluate how various factors affect brain kinematics during angular head kinematics. READ MORE

  5. 3. Car-to-Car Side Impacts: Occupant Injuries, Test Methods, and the Development and Evaluation of Protective Systems

    Author : Yngve Håland; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

    Abstract : The present work addresses the problem of injuries following car-to-car side collisions. The injuries in this type of impact have been evaluated to form the basis for the development of test methods and for the principles of protective systems. Side impacts give rise to relatively more severe injuries than frontal impacts. READ MORE

  6. 4. Innovating Recycling of End-of-Life Cars

    Author : Magnus Andersson; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; End-of-Life; Scarce Metal; Material Flow Analysis; Vehicle; Technological Innovation System; Car; Critical Material; Recycling;

    Abstract : There are currently a billion cars in use worldwide, and car design trends point at increasing variety in material utilisation. Cars today contain several types of steel and aluminium, an assortment of textiles and padding materials, and an increasing amount of polymers and scarce metals. READ MORE

  7. 5. Burial textiles : Textile bits and pieces in central Sweden, AD 500–800

    Author : Anita Malmius; Birgit Arrhenius; Kerstin Lidén; Gunilla Eriksson; Eva Andersson Strand; Stockholms universitet; []
    Keywords : HUMANIORA; HUMANITIES; textiles; boat-graves; Merovingian Period; Vendel; Valsgärde; Birka; elite burials; archaeology; Sweden; Migration Period; Archaeological Science; laborativ arkeologi;

    Abstract : This thesis concerns the role and use of archaeological textiles (AT) deposited in inhumation and cremation burials in Sweden dating from 500–800 AD. The AT are studied in their burial context, including all other grave goods, emphasizing that they were as important as a source for understanding society in prehistory as they are today. READ MORE
