  1. 16. Clinical and arthroscopic assessment of wrist ligament injuries and instability

    Författare :Jonny K Andersson; Göteborgs universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; wrist; wrist arthroscopy; carpal ligaments; scapholunate ligament; lunotriquetral ligament; triangular fibrocartilage complex; distal radio-ulnar joint; instability; magnetic resonance imaging; forearm rotation torque; children; adolescents;

    Sammanfattning : Wrist ligament injuries are common after trauma, especially when concomitant dislocated radius fractures are present. The diagnostics of scapholunate (SL), lunotriquetral (LT) and triangular fibrocartilage complex (TFCC) injuries are challenging and most often dependent on magnetic resonance imaging (MRI) examination or invasive arthroscopy.

  3. 17. Titled and graded anisotropy FePt and FePtCu thin films for the application of hard disk drive and spin torque oscillators

    Författare :Yeyu Fang; Johan Åkerman; Anna Delin; KTH; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Physics; Fysik;

    Sammanfattning :  The FePt and FePtCu thin films with graded anisotropy and titled anisotropy are utilized to solve both the magnetic recording ‘‘trilemma’’ of the hard disk drives (HDDs) and the large field operation problem of spin torque oscillators (STOs). We have successfully realized the FePtCu thin films with graded anisotropy. LÄS MER

  4. 18. Distal radioulnar joint: arthroplasty and strength assessments

    Författare :Peter Axelsson; Göteborgs universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Distal Radioulnar joint arthroplasty; Forearm torque and lifting strength measurements; Normative data; Reliability; Validity; Responsiveness;

    Sammanfattning : The growing interest in distal radioulnar (DRUJ) disorders underlines the need for further improved evaluations of treatment outcome. Load-bearing and optimising torque are important features of the DRUJ, but they are rarely measured when assessing DRUJ interventions. LÄS MER

  5. 19. Velocity controlled dynamometry and gait analysis : development of methods and applications

    Författare :Lennart Gransberg; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :Dynamometry; torque; measurement error; overshoot; isokinetic; concentric; eccentric; gait analysis; three-dimensional; electrogoniometer; electromagnetic tracking;

    Sammanfattning : The isokinetic systems developed in the present study can measure torque in maximal voluntary and passive movements. The torque recordings may be combined with surface EMG recordings from pairs of antagonistic muscles involved in the movement. Healthy subjects and patients with spastic paresis have been examined.

  7. 20. Dry Clutch Modeling, Estimation, and Control

    Författare :Andreas Myklebust; Lars Eriksson; Joško Deur; Linköpings universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

    Sammanfattning : Increasing demands on comfort, performance, and fuel efficiency in vehicles lead to more complex transmission solutions. One such solution is the Automated Manual Transmission (AMT). It works just like an ordinary manual transmission but the clutch and the gear selection are computer controlled. LÄS MER
