  1. 1. Early Physiotherapy in the Neurointensive Care Unit - Passive Physiotherapy Interventions

    Författare :Annelie Thelandersson; Göteborgs universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Physiotherapy; Brain injury; Stroke; Intensive care unit; Prone position; Range of motion; Continuous passive motion; Intra cranial pressure; Cerebral perfuison pressure; Haemodynamics;

    Sammanfattning : Background: In critically ill patients, treated in the neurointensive care unit (NICU) because of severe brain injury or stroke, physical activities have been restricted to a minimum due to the potential risks of complications and adverse events. Nevertheless, passive physiotherapy treatments are widely used without conclusive evidence for their safety. LÄS MER

  3. 2. Nature-inspired passive flow control using various coatings and appendages

    Författare :Ugis Lacis; Shervin Bagheri; Christophe Eloy; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; flow control; passive appendage; surface coating; pressure drag; friction drag; Flödeskontroll; passiva bihang; ytbeläggning; tryckmotstånd; friktionsmotstånd;

    Sammanfattning : There is a wide variety of tails, fins, scales, riblets and surface coatings, which are used by motile animals in nature. Since organisms currently living on earth have gone through millions of years of evolution, one can expect that their design is optimal for their tasks, including locomotion. LÄS MER

  4. 3. Principles for planning and analyzing motions of underactuated mechanical systems and redundant manipulators

    Författare :Uwe Mettin; Anton Shiriaev; Alin Albu-Schäffer; Umeå universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Motion Planning; Underactuated Mechanical Systems; Redundant Manipulators; Virtual Holonomic Constraints; Orbital Stabilization; Human Movement; Walking Robots; Hydraulic Manipulators; Electrical engineering; Elektroteknik; Automatic Control; reglerteknik;

    Sammanfattning : Motion planning and control synthesis are challenging problems for underactuated mechanical systems due to the presence of passive (non-actuated) degrees of freedom. For those systems that are additionally not feedback linearizable and with unstable internal dynamics there are no generic methods for planning trajectories and their feedback stabilization. LÄS MER

  5. 4. Underactuated mechanical systems : Contributions to trajectory planning, analysis, and control

    Författare :Pedro La Hera; Anton Shiriaev; Ambarish Goswami; Umeå universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Underactuated mechanical systems; mechanical systems with impacts; trajectory planning; periodic trajectories; orbital stabilization; walking robots; virtual holonomic constraints; transverse linearization; Automatic control; Reglerteknik; Automatic Control; reglerteknik;

    Sammanfattning : Nature and its variety of motion forms have inspired new robot designs with inherentunderactuated dynamics. The fundamental characteristic of these controlled mechanicalsystems, called underactuated, is to have the number of actuators less than the number ofdegrees of freedom. LÄS MER

  7. 5. Prosthetic Foot Control for Ground Adaptation

    Författare :Wolfgang Svensson; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; autonomous systems; kinematical sensors; Foot prosthesis; embedded computing; sensor fusion;

    Sammanfattning : Wearers of prosthetic feet find walking on inclined ground difficult or uncomfortable. A major reason for this is a limitation in ankle motion in existing prostheses. LÄS MER
