  1. 1. Aspects on measuring electrical current utilizing magnetic zero-flux technique

    Författare :Maria Hammarqvist; Chalmers University of Technology; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Current Transformer; AC Current; Frequency Response; Measurement Uncertainty; Traceability; Zero-Flux Measurement Technique; Zero-Flux;

    Sammanfattning : The utilization of high accuracy measurements of electrical quantities is a prerequisite for the development of modern society. Generally, measurements serve different purposes and hence the criteria for the measurement equipment and method are different. LÄS MER

  3. 2. Inductive measurement of narrow gaps for high precision welding of square butt joints

    Författare :Edvard Svenman; Anna-Karin Christiansson; Högskolan Väst; []
    Nyckelord :ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; 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

  4. 3. Health care need : Meaning and measurement

    Författare :Per-Erik Liss; Lennart Nordenfelt; Linköpings universitet; []
    Nyckelord :SOCIAL SCIENCES; SAMHÄLLSVETENSKAP; SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; Concept of needs; health needs and health care needs. Needs assessment; resource allocation; setting health priorities; INTERDISCIPLINARY RESEARCH AREAS; TVÄRVETENSKAPLIGA FORSKNINGSOMRÅDEN;

    Sammanfattning : Determining how the health services are to be, and allocating health care, are basic issues in health policy. Need is a frequent criterion for an ethical or rational allocation of health service resources. The primary aim of this study is to analyse and explicate the concept of health care need. Methods for measuring health care need are examined. LÄS MER

  5. 4. In the eyes of the beholder: On innovation metrics : A study on innovation metrics in changing strategic contexts

    Författare :Ilse Svensson De Jong; Innovationsteknik; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Innovation; Metrics; Measurement; performance measurement; Systematic Literature Review; Case study; Participatory action research PAR ;

    Sammanfattning : Innovation measurement and metrics have fascinated scholars from several disciplines over the last decade. Allthese diverse contributions, however, have resulted in a current state of knowledge that is signified by largenumbers of articles without clear integration and synthesis. LÄS MER

  7. 5. Resource characterization and variability studies for marine current power

    Författare :Nicole Carpman; Karin Thomas; Mats Leijon; Sandra Eriksson; AbuBakr S. Bahaj; Uppsala universitet; []
    Nyckelord :ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Marine current energy; tidal currents; wake; variability; renewable energy; ADCP; flow measurement; Engineering Science with specialization in Science of Electricity; Teknisk fysik med inriktning mot elektricitetslära;

    Sammanfattning : Producing electricity from marine renewable resources is a research area that develops continuously. The field of tidal energy is on the edge to progress from the prototype stage to the commercial stage. LÄS MER
