  1. 1. Analysis of a shape morphing structural battery: manufacturing, analytical modeling and numerical simulation

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

    Författare :Alfredo Bici; [2023]
    Nyckelord :;

    Sammanfattning : A reduction in the global use of fossil fuels is necessary when striving for a more sustainable future. One key strategy in the transition from fossil fuels is electrification. This strategy is particularly prominent within the transport sector, where more efficient ways to store electric energy are being pursued. LÄS MER

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

    Författare :WULLSCHLEGER LÉA; [2023]
    Nyckelord :Liquefaction cycle; multi-streams heat exchanger; Matlab; PROOSIS; AMESIM; ArianeGroup;

    Sammanfattning : This paper presents the master thesis work done at ArianeGroup on the development and characterization of multi-streams heat exchangers for liquefaction cycle analysis in the context of hydrogen mobility. In 2015, the Paris Agreements aimed at strengthening the global response to the threat of climate change by keeping the temperature rise below 1. LÄS MER

  4. 3. 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

    Sammanfattning : The electric vehicle segments of companies have broadened, and their sales have increased in the past decade. The electric motorcycle sector is growing fast, with improved technology on electric powertrains, increased ranges, charging speeds, and infrastructure. LÄS MER

  7. 5. Climbing to new heights : The importance of considering passengers on the flight towards more sustainable forms of aviation

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

    Författare :Eleanor Dowds; [2023]
    Nyckelord :Sustainable aviation; passengers; attitudes; SAF; biofuels; Diffusion of Innovation; Hållbart flyg; passagerare; attityder; SAF; biobränsle; Diffusion of Innovation;

    Sammanfattning : Within the commercial aviation industry, with its ever increasing global carbon footprint rising with consumer demand, the need for more sustainable forms of aviation has become more necessary than ever. With growing demands for emission reductions and better energy management practices across all industries in initiatives such as the Paris Agreement, there has never been a more pressing time to explore the existing and potential pathways towards more sustainable forms of aviation.
