  1. 6. Touching on elements for a non-invasive sensory feedback system for use in a prosthetic hand

    Författare :Pamela Svensson; Avdelningen för Biomedicinsk teknik; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; sensory feedback; amputation; referred sensation; non-invasive feedback; upper limb prosthetics; body ownership;

    Sammanfattning : Hand amputation results in the loss of motor and sensory functions, impacting activities of daily life and quality of life. Commercially available prosthetic hands restore the motor function but lack sensory feedback, which is crucial to receive information about the prosthesis state in real-time when interacting with the external environment.

  3. 7. Faster. Stronger. Better? : designing for enhanced engagement of extreme sports

    Författare :Rouien Zarin; Andreas Lund; Johan Redström; Ambra Trotto; Tom Djajadiningrat; Umeå universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; HUMANIORA; HUMANITIES; constructive design research; design prototypes; prototypes; design research; research through design; embodiment; sports; interaction; technology; user experience; human computer interaction; tactile; feedback; design; design;

    Sammanfattning : The human body is capable of very rich and complex movements and gestures which we use in everyday life to manipulate, navigate and negotiate the world around us—it is our interface for human experience. However, as technology advances it simultaneously shrinks, moving closer to our bodies, intertwining with the many facets of our lives and positions itself between our experiences of the physical environments around us.

  4. 8. Neuronal mechanisms of feedback postural control

    Författare :Li-Ju Hsu; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :postural control; equilibrium; body configuration; reticulospinal neurons; stretch receptor neurons; galvanic vestibular stimulation; artificial feedback; locomotion; spinalization; rabbit; lamprey;

    Sammanfattning : Different species maintain a basic body posture due to the activity of the postural control system. An efficient control of the body orientation, as well as the body configuration, is important for standing and during locomotion. LÄS MER

  5. 9. Towards clinically viable neuromuscular control of bone-anchored prosthetic arms with sensory feedback

    Författare :Enzo Mastinu; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Electromyography; prosthetics; sensory feedback; closed-loop; osseointegration; embedded system; pattern recognition; neurostimulation;

    Sammanfattning : Promising developments are currently ongoing worldwide in the field of neuroprosthetics and artificial limb control. It is now possible to chronically connect a robotic limb to bone, nerves, and muscles of a human being, and to use the signals sourced from these connections to enable movements of the artificial limb.

  7. 10. Efficient Online Learning under Bandit Feedback

    Författare :Stefan Magureanu; Alexandre Proutiere; Odalric-Ambrym Maillard; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; multi-armed bandits; reinforcement learning; learning to rank; Electrical Engineering; Elektro- och systemteknik;

    Sammanfattning : In this thesis we address the multi-armed bandit (MAB) problem with stochastic rewards and correlated arms. Particularly, we investigate the case when the expected rewards are a Lipschitz function of the arm and extend these results to bandits with arbitrary structure that is known to the decision maker.
