    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; reumatologi; Organizational science; Organisationsteori; Production technology; Produktionsteknik; muskelsystem; Skelett; rheumatology locomotion; muscle system; Skeleton; Risk Assessment; Manufacturing; Musculoskeletal disorders; Human Factors; Organisational Development; Production System Design; Strategy;

    Sammanfattning : Poor ergonomics in production systems can compromise performance and cause musculoskeletal disorders (MSDs), which pose a huge cost to society, companies, and afflicted individuals. This thesis presents a research trajectory through the problem space by: 1) Identifying and quantifying workplace risk factors for MSDs, 2) Identifying how these risks may relate to production strategies, and 3) Developing an approach to integrating ergonomics into a companies’ regular development work.

  4. 3. Characterization of Conduction and Polarization Properties of HVDC Cable XLPE Insulation Materials

    Författare :Hossein Ghorbani; Hans Edin; Erling Ildstad; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; HVDC insulation; power cable insulation; cross-linked polyethylene insulation; conductivity; dielectric losses; space charge; HVDC isolation; kraftkabel isolation; tvärbunden polyeten isolationsmaterial; elektrisk ledningsförmåga; dielektriska förluster; rymdladdning; Electrical Engineering; Elektro- och systemteknik;

    Sammanfattning : Since its first introduction in 1998, extruded direct current (DC) cable technology has been growing rapidly leading to many cable system installations with operation voltages up to 320 kV. Cable manufacturers invest heavily on technology development in this field and today extruded DC cable systems for operation voltages as high as 525 kV are commercially available. LÄS MER
