  1. 21. A New Shoulder for the THOR Dummy Intended for Oblique Collisions

    Författare :Fredrik Törnvall; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Shoulder; Shoulder range-of-motion; Volunteers; Kinematics; Biofidelity; Post Mortem Human Subjects; THOR; Crash test dummy; Oblique collision;

    Sammanfattning : Offset and oblique frontal car collisions represent a type of crash in which severe and fatal injuries frequently occur. This indicates the importance of having protective systems in vehicles for these types of collisions. LÄS MER

  3. 22. Integration of database technology and multibody system analysis

    Författare :Claes Tisell; KTH; []
    Nyckelord :machine element; dynamic systems; multibody system kanes equations of motion; simulation; submodel; functional assembly;

    Sammanfattning : The design process includes many different activities inwhich various computational mechanics tools are used forbehaviour modelling of mechanical systems and their buildingblocks, e.g. machine elements. These tools usually supportlarge and complex models and they produce large quantities ofdata with a high degree of complexity. LÄS MER

  4. 23. Analysis of body motions based on optical markers. Accuracy, error analysis and clinical applications

    Författare :Roy Tranberg; Göteborgs universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Instrumented gait analysis Motion analysis Skin markers Optical tracking system;

    Sammanfattning : This thesis aims to evaluate the influence of soft-tissue artefacts on analyses of body motions based on optical markers. A second aim is to apply instrumented gait analysis in clinical situations. Introduction: Instrumented gait analysis has been used since 1960 as a clinical evaluation/investigative tool at orthopaedic clinics. LÄS MER

  5. 24. Movement artifact reduction in laser Doppler blood flowmetry : myocardial perfusion applications

    Författare :MG Daniel Karlsson; Karin Wårdell; Knut Kvernebo; Linköpings universitet; []
    Nyckelord :MEDICINE; MEDICIN;

    Sammanfattning : Laser Doppler perfusion monitoring (LDPM) and imaging (LDPI) enable assessment of tissue microvascular perfusion. The techniques are based on the Doppler broadening of the optical spectrum occurring when coherent laser light is scattered by moving red blood cells (RBC). LÄS MER

  7. 25. Combined speckle interferometry and speckle correlation for non-destructive testing

    Författare :Angelica Andersson; Luleå tekniska universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Experimental Mechanics; Experimentell mekanik;

    Sammanfattning : When a sample is studied during loading in a tensile test machine, the sample is often exposed to rigid body motions during loading at the same time as it deforms due to tension. Therefore, the small deformation field is hard, or impossible, to measure when it is overlaid by a large motion. LÄS MER
