  1. 1. Input Estimation for Teleoperation Using Minimum Jerk Human Motion Models to Improve Telerobotic Performance

    Detta är en avhandling från Stockholm, Sweden : KTH

    Författare :Christian Smith; KTH.; [2009]
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Robot; Teleoperation; Human Motion Models; TECHNOLOGY Information technology Computer science; TEKNIKVETENSKAP Informationsteknik Datavetenskap;

    Sammanfattning : This thesis treats the subject of applying human motion models to create estimators for the input signals of human operators controlling a telerobotic system.In telerobotic systems, the control signal input by the operator is often treated as a known quantity. However, there are instances where this is not the case. LÄS MER

    Detta är en avhandling från Göteborg : Institute of Medicine at Sahlgrenska Academy, University of Gothenburg

    Författare :Per Jonsson; Göteborgs universitet.; Gothenburg University.; [2009]
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Wrist joint; Finger joint; Electromyography; Accuracy; Electrogoniometry; Input device; Information and communication technology; Mobile phone; Muscle activity; Posture; Thumb; Wrist;

    Sammanfattning : Correct measurements of the joints’ extreme postures, velocity and repetitiveness are important for studies of the origin of musculoskeletal disorders. Posture measurements of wrist and thumb joints may also provide insights into input device designs that may reduce effort and/or facilitate productivity. LÄS MER

  4. 4. Physical exposure, musculoskeletal symptoms and attitudes related to ICT use

    Detta är en avhandling från Göteborg : Institute of Medicine at Sahlgrenska Academy, University of Gothenburg

    Författare :Ewa Gustafsson; Göteborgs universitet.; Gothenburg University.; [2009]
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Input device; Wrist movements; Electrogoniometry; EMG; Muscle activity; Thumb movements; Working technique; Information and communication technology; Computer mouse; Mobile phone;

    Sammanfattning : High prevalence of musculoskeletal symptoms/disorders in neck and upper extremities are reported among computer users. Considering the widespread use of information and communication technology (ICT) and mobile phones becoming more and more like computers with small keyboards it is of importance to identify the factors and conditions related to this use, that influence our health.

  5. 5. EMI from Switched Converters – Simulation Methods and Reduction Techniques

    Detta är en avhandling från Chalmers University of Technology

    Författare :Andreas Karvonen; Chalmers tekniska högskola.; Chalmers University of Technology.; [2011]
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Elektronik; Electronics; Elektroteknik; Electrical engineering; Elkraftteknik; Electric power engineering; Semiconductor device measurements; semiconductor device modeling; diode modeling; diode reverse recovery; EMI; conducted emissions; DC DC converters; state space methods;

    Sammanfattning : In this thesis, the conducted EMI from switched power converters has been analyzed using various existing models, own-derived models as well as measurements. The ingoing passive components in a switching converter have been modeled with respect to their high frequency behavior and the static and dynamic behavior of the active semiconductors has been analyzed.
