  1. 16. Application of Lamb waves using piezoelectric technique for structure health monitoring

    M1-uppsats, KTH/Hälsoinformatik och logistik

    Författare :Simon Mauritz; [2023]
    Nyckelord :Structural health monitoring SHM ; damage detection; Lamb waves; piezoelectric PZT ; printed circuit board PCB ; circuit simulation; Strukturell hälsoövervakning SHM ; skadedetektering; Lambvågor; piezoelektrisk PZT ; printed circuit board PCB ; kretssimulering;

    Sammanfattning : Structural health monitoring (SHM) is damage detection strategy for aerospace, civiland mechanical infrastructure. This project tries to show that Lamb waves, that are being generated and sensed with piezoelectric transducers, can be used for damage detection in a SHM system. LÄS MER

  3. 17. A Feasibility Analysis of Natural Composite Alternatives in High Performance Sailing Vessels

    Master-uppsats, KTH/Lättkonstruktioner, marina system, flyg- och rymdteknik, rörelsemekanik

    Författare :Sabrina Smith; [2023]
    Nyckelord :F50 catamaran; sustainable materials; marine applications; flax laminates; mechanical testing; environmental analysis; weight distribution; yacht performance;

    Sammanfattning : The construction of high-performance vessels like the F50 catamaran has traditionally prioritized advanced composite materials and performance-driven design. However, there is a growing need to incorporate sustainable materials and practices, with their performance in marine applications remaining relatively unknown. LÄS MER

  4. 18. Investigation of new refrigerants for a large-scale heat pump and evaluation of system performance

    Master-uppsats, Linköpings universitet/Mekanisk värmeteori och strömningslära

    Författare :Hanna Grahn; Matilda Eriksson; [2023]
    Nyckelord :Large-scale heat pump; refrigerant; COP;

    Sammanfattning : Heat production accounted in 2021 for 50 % of the energy end use globally, where a strongconnection to fossil sources still exists. Large-scale electrical heat pumps can therefore have akey role in the energy system to enable a decreased reliance on fossil fuels and at the same timecontribute to stable system when incorporating more intermittent renewable sources.

  5. 19. Brotthållfastheten på långtids-vattenförvarade monolitiska 3-leds-broar i flerskiktad zirkonia med olika konnektordimensioner och placering i disk.

    Kandidat-uppsats, Malmö universitet/Odontologiska fakulteten (OD)

    Författare :Chab Mina; Moradi Mostafa; [2023]
    Nyckelord :Ceramics; Zirconia FDPs; multilayered zirconia; keram; 3-ledbro; Fler skiktad Zirconia;

    Sammanfattning : Aim: The aim is to evaluate the fracture strength and fracture type of long-term water-stored monolithic 3-unit multilayered zirconia fixed dental prostheses (FDPs) depending on connector dimension and placement in disc. Material and method: Thirty-two 3-unit FDPs (212223) of KATANATM Zirconia Yttria Multilayered (YML) were divided into four groups (n=8/group). LÄS MER

  7. 20. A final drive device for torque vectoring in small racing cars

    Master-uppsats, Lunds universitet/Institutionen för energivetenskaper

    Författare :Sven Kalkan; [2023]
    Nyckelord :Torque vectoring; differential; formula student; racecar; racing; BorgWarner; product development; Technology and Engineering;

    Sammanfattning : The agility of the car can be improved by distributing the longitudinal tire forces unevenly between the wheels. The resulting yaw moment helps the car to steer in transient driving scenarios, like on a slalom course. The available grip in steady state cornering can also be increased along with stability.
