  1. 16. Complicated vacuum extraction : focus on traction force

    Författare :Kristina Pettersson; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :;

    Sammanfattning : Introduction: Vacuum extraction is a common operative vaginal delivery in the final stage of labor, and generally considered a safe alternative to emergency cesarean section. However, there is insufficient evidence regarding the causes of the rare but severe perinatal complications that may occur, such as intracranial or subgaleal hemorrhage, and possibly also asphyxia related encephalopathy.

  3. 17. Automation and traction control of articulated vehicles

    Författare :Ulf Andersson; Vladimir Vantsevich; Luleå tekniska universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Reglerteknik; Control Engineering;

    Sammanfattning : Articulated machines such as load-haul-dump machines, wheel loaders and haulers operate in many different environments and driving conditions. In particular they need to be able to perform well with road conditions and loads that can change drastically, setting hard requirements on performances and robustness. LÄS MER

  4. 18. A Permanent Magnet Traction Motor for Electric Forklifts : Design and Iron Loss Analysis with Experimental Verifications

    Författare :Yung-Kang Robert Chin; Chandur Sadarangani; Fabio Crescimbini; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Electrical engineering; Elektroteknik;

    Sammanfattning : This thesis presents the design analysis of a permanent magnet synchronous motor (PMSM) for the traction application in electric forklifts. Within the scope of the study, an existing induction traction motor for electric forklifts benchmarks the expected performances of the proposed PMSM designs, as design specifications. LÄS MER
