  1. 6. Inductive measurement of narrow gaps for high precision welding of square butt joints

    Författare :Edvard Svenman; Anna-Karin Christiansson; Högskolan Väst; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Eddy current; Seam tracking; Measurement; Laser beam welding; Production Technology; Produktionsteknik; Manufacturing and materials engineering; Produktions- och materialteknik;

    Sammanfattning : A recent method in aero engine production is to fabricate components from smaller pieces, rather than machining them from large castings. This has made laser beam welding popular, offering high precision with low heat input and distortion, but also high productivity. LÄS MER

  3. 7. Measurement and Application of Multidirectional Mobilities

    Författare :Michael A. Sanderson; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; source signal filtering; mass loading; rotational mobility; rotational inertia loading; multidirectional mechanical mobility; moment mobility; structural intensity; measurement techniques; vibration isolation;

    Sammanfattning : The direct measurement of moment mobility, employing a twin exciter technique, is theoretically and experimentally examined. This is continued by a theoretical and experimental analysis of an improved technique using source signal filtering, for two degrees of freedom, for the measurement of multidirectional mobilities.

  4. 8. Measurement and prediction of outcome. Application in fusion surgery for chronic low backpain. The Swedish lumbar spine study

    Författare :Olle Hägg; Göteborgs universitet; []
    Nyckelord :Chronic low back pain; clinical outcome; global assessment; measurement; ; minimal clinically important difference; pain drawing; physical disability; predictors.;

    Sammanfattning : Background: Outcome of surgery for chronic low back pain should be documented ina standardised and reproducible fashion to establish evidence of its benefit. Measurement of outcome requires validated instruments, which have the ability to detect functionalchanges perceived as beneficial by the patient. LÄS MER

  5. 9. Multidirectional Mobilities - Advanced Measurement Techniques and Applications

    Författare :Lars H. Ivarsson; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; R-DOFs; substructuring; measurement techniques; rotational mobility; multidirectional mechanical mobility; hybrid coupling; coupling; moment mobility; impedance coupling; consistency;

    Sammanfattning : Today high noise-and-vibration comfort has become a quality sign of products in sectors such as the automotive industry, aircraft, components, households and manufacturing. Consequently, already in the design phase of products, tools are required to predict the final vibration and noise levels. LÄS MER

  7. 10. Measurement, Modeling, and Characterization for Power-Aware Computing

    Författare :Bhavishya Goel; Chalmers tekniska högskola; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; transactional memory; power management; energy characterization; power measurement; power estimation; power-aware scheduling;

    Sammanfattning : Society’s increasing dependence on information technology has resulted in the deployment of vast compute resources. The energy costs of operating these resources coupled with environmental concerns have made power-aware computingone of the primary challenges for the IT sector. LÄS MER
