  1. 16. Neck-Injuries in Rear-End Car Collisions: Sites and Biomechanical Causes of the Injuries, Test Methods and Preventive Measures

    Författare :Mats Svensson; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

    Sammanfattning : The present work addresses the problem of neck injuries following rear-end car collisions. Biomechanics and sites of the injuries have been investigated. A new dummy neck has been developed and used to study the influence of different seat properties on occupant kinematics. LÄS MER

  3. 17. Studies on structural and biomechanical responses in seat integrated safety belt configurations

    Författare :Anders Gavelin; Luleå tekniska universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Hållfasthetslära; Solid Mechanics;

    Sammanfattning : The common 3-point safety belt usually has some anchor points on the car body. However, it is also possible to mount all anchor points on the seat structure. In general, different studies show some advantages with seat integrated safety belts. Thus, further investigations are motivated. LÄS MER

  4. 18. Energy Absorbing Material Concepts for Automotive Accident Injury Prevention

    Författare :Rickard Juntikka; KTH; []
    Nyckelord :Head impact; energy absorption; cellular materials; automotive; dynamic; pedestrian; interior; compression; shear; finite element analysis; optimisation;

    Sammanfattning : Although automotive safety has experienced a rapiddevelopment during the last decades, traffic related accidentsrank very high in many countries in terms of cause of death.Statistics show that the head is the body region mostfrequently injured in motor vehicle accidents and the primarycause of death is head injuries.

  5. 19. A tailored biocompatible neural interface for long term monitoring in neural networks

    Författare :Per Köhler; Neuronano Research Center (NRC); []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Brain-machine interfaces; neuroinflammation; somatosensory cortex; hyperalgesia; allodynia;

    Sammanfattning : Neural interface electrodes that can record from neurons in the brain for long periods of time will be of great importance to unravel how the brain accomplishes its functions. However, current electrodes usually cause significant glia reactions and loss of neurons within the adjacent brain parenchyma. LÄS MER

  7. 20. Study of a Large Deformable Mirror Concept

    Författare :Rikard Heimsten; Astronomi - Genomgår omorganisation; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Large deformable mirror - Adaptive optics - Distributed Control - Local control: actuator family - Faceplate: vibration modes - Faceplate: Dimensionless modal analysis;

    Sammanfattning : It is attractive to integrate a large deformable mirror for adaptive optics into an astronomical telescope rather than using relay optics within an auxiliary instrument. However, the resulting large deformable mirror can be expensive, particularly for extremely large telescopes. LÄS MER
