  1. 1. Influence of current harmonics on the degradation of the catalyst coated membrane in PEMFC

    University essay from KTH/Kemiteknik

    Author : Evelina Ahlén Norberg; [2022]
    Keywords : Proton Exchange Membrane Fuel Cell; Ripple Current; Current Harmonics; Degradation; Marine transportation; Polymerelektrolytbränslecell; Rippelström; Strömoscillation; Åldring; Sjötransport;

    Abstract : Sjöfarten är idag dominerad av förbränningsmotorer som är beroende av fossila drivmedel. Elektrifiering är en av huvudstrategierna för att möjliggöra fossilfri energiförsörjning inom internationell sjöfart. READ MORE

  3. 2. Assessment of optimal suspension systems with regards to ride under different road profiles

    University essay from KTH/Fordonsdynamik

    Author : Adithya Murali; Pratik Hindraj Vaje; [2021]
    Keywords : Ride comfort; Handling; Road profiles; ADAMS; Shaping filter method; Sinusoidal approximation method; Coherence; ISO 8608; Acceleration PSD s; Genetic Algorithm optimisation; ISO 2631.; åkkomfort; Kurvkörningsegenskaper; Vägprofiler; ADAMS; Formningsfiltermetod; Sinusformad approximationsmetod; Koherens; ISO 8608; Acceleration PSDs; Genetisk algoritmoptimering.;

    Abstract : Passenger ride vibration comfort is a critical aspect to consider while developing any vehicle and there is a need to understand how the occupants would be affected when driving on different road profile roughness. Hence, road profile generation is critical as road profiles are used as inputs to simulation tools to investigate vehicle dynamic behaviour in depth. READ MORE

  4. 3. 3D-Printed Geodesic Reflective Luneburg Lens Antenna for X-Band

    University essay from KTH/Skolan för elektroteknik och datavetenskap (EECS)

    Author : David Oxelmark; Lukas Jonasson; [2021]

  5. 4. The Inclusion of Stratification in Wind Analysis; A New Linearized Code

    University essay from KTH/Strömningsmekanik och Teknisk Akustik

    Author : Roland Nyberg; [2020]
    Keywords : Wind Energy; Stratification; Speed-up effect; Monin-Obukhov similarity theory; Vindenergy; Stratifikation; Speed-up effekt; Monin-Obukhov teori;

    Abstract : Wind energy is rapidly growing around the world as non-renewable energy sources are being phased out. To maximize the energy production, it is crucial to construct new wind turbines at locations where the average wind speed is high. An accurate wind assessment of a new potential site is thus essential in the development of new wind farms. READ MORE

  6. 5. Calculating Center of Mass Using List Mode Data from PET Biograph128 mCT-1104

    University essay from KTH/Medicinteknik och hälsosystem

    Author : Lukas Rane; Henrik Runeskog; [2019]
    Keywords : PET; List Mode; Image Reconstruction; e7-tools; Siemens; Center of Mass; PET; List Mode; Bildrekonstruktion; e7-tools; Siemens; Masscentrum;

    Abstract : A common problem within positron emission tomography examinations of the brain is the motion of the patient. If the patients ́ head moves during an examination all the data acquired after the movement will not be suited for clinical use. This means that a lot of data recovered from PET is not used at all.
