  1. 6. Design of a Bistable Origami Stent with Pneumatic Actuation

    Uppsats för yrkesexamina på avancerad nivå, Luleå tekniska universitet/Institutionen för system- och rymdteknik

    Författare :Michelle von Rosen; [2023]
    Nyckelord :;

    Sammanfattning : What if stents could be easier removed when complications arise or removed once theirjob has been done? No matter how perfect a stent design becomes, the fundamental issueis that a foreign object in the body under extended periods eventually will cause devicedegradation and complications. So instead of making a long-term solution of a perfectstent, the focus in this paper is redirected from expensive materials to a simple design,with simple materials. LÄS MER

  3. 7. New process for leak detection in truck pneumatic systems during production using an ultrasound camera

    Master-uppsats, Uppsala universitet/Industriell teknik

    Författare :Henrik Gustafsson; Malva von Schenck; [2023]
    Nyckelord :industry; leak detection; leak positioning; pneumatic system; pressure drop test; production; quality assurance; ultrasound camera;

    Sammanfattning : The process of producing compressed air in the industry today is highly energy inefficient. Up to 75 % of the energy spent on producing compressed air to the compressed air systems (CASs) is wasted. Out of the produced air, 24 % is wasted due to air leaks. LÄS MER

  4. 8. Dynamic Modelling of a Fluidic Muscle with a Comparison of Hysteresis Approaches

    Master-uppsats, KTH/Skolan för industriell teknik och management (ITM)

    Författare :Tess Antonsson; [2023]
    Nyckelord :Mechatronics; Soft Actuators; Pneumatic Artificial Muscles; Dynamic Modelling; Hysteresis; Maxwell-Slip Model; Generalised Bouc-Wen Model; Mekatronik; Mjuka Ställdon; Pneumatiska Artificiella Muskler; Dynamisk Modellering; Hysteres; Maxwell-Slip Modell; Generaliserad Bouc-Wen Modell;

    Sammanfattning : n recent years, there has been a surge in interest and research into the utilisation of soft actuators within the field of robotics, driven by the novel capabilities of their inherently compliant material. One such actuator is the Pneumatic Artificial Muscle (PAM) which offers a high power-to-mass ratio, compliance, safety, and biological mimicry when compared to their traditional counterparts.

  5. 9. Rörtransportmetodens inverkan på hemolys och plasmakalium

    Kandidat-uppsats, Örebro universitet/Institutionen för hälsovetenskaper

    Författare :Shamira Kasajja; [2023]
    Nyckelord :Hemolysis; tube transport; potassium; ion-selective electrode method; Hemolys; Rörpost; Kalium och Jonselektiv elektrodmetod;

    Sammanfattning : Interferenser i klinisk kemi uppstår när en substans stör mätningen av olika komponenter i urin, cerebrospinalvätska och blod, vilket påverkar mätresultatet. Exempel på interferenser inkluderar hemolys, lipemi och ikterus. Hemolys kan orsakas både in vivo och in vitro, men in vitro är betydligt vanligare. LÄS MER

  7. 10. Prototyping of an automated cyclic Neutron Activation Analysis setup

    Master-uppsats, Lunds universitet/Kärnfysik; Lunds universitet/Fysiska institutionen

    Författare :Cornelius Maurer; [2022]
    Nyckelord :Nuclear Physics; Neutron activation analysis; cyclic-NAA; Physics and Astronomy;

    Sammanfattning : A prototype Neutron Activation Analysis (NAA) setup based on a Deuterium-Tritium (DT) neutron generator is under development at Lund University. It serves as proof-of-principle for NAA based on a Compact Accelerator-driven Neutron Source. LÄS MER
