Objective: Find out how airlines can reduce their emissions and become more sustainable. LÄS MER

  3. 2. Aircraft Contrail Prediction for Commercial Flights

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

    Författare :Chirag Kundgol; [2022]
    Nyckelord :Contrail prediction; Aircraft trajectory optimisation; Kondensstrimmor; förutsägelse; optimering;

    Sammanfattning : The prediction of contrails have been studied since the 1930s primarily for militaryapplications. In present times, contrail avoidance strategies are gaining popularity insustainable aviation. In this project, the theory behind their formation, persistenceand the mitigation strategies are explored, studied and implemented. LÄS MER

  4. 3. Design setup for haptic devices for surgery applications

    Master-uppsats, KTH/Maskinkonstruktion (Inst.)

    Författare :Khaled El Musleh; [2016]
    Nyckelord :Medical Simulator; haptic device; Setup; hardware platform; surgery; Medicinsk simulator; hatiska enheter; setup; kirurgi;

    Sammanfattning : In a way to help doctors and medical students train on performing difficult surgeries before entering the stressful operating room, DevinSense is developing a generic hardware platform for medical simulation. The system is used together with specific simulation software derived from real patient data and optimized towards the user specifications. LÄS MER

  5. 4. Do contrails seek clear skies?

    Kandidat-uppsats, Lunds universitet/Fysiska institutionen; Lunds universitet/Förbränningsfysik

    Författare :Cecilia Heldmann; [2014]
    Nyckelord :Contrails; condensation trails; clouds; meteorology; convective areas; clear skies; wind field; radiative forcing; Physics and Astronomy;

    Sammanfattning : Contrails are the visible line-shaped clouds that can be seen to form behind aircrafts if the air is saturated with respect to liquid. Furthermore, if the air is supersaturated with respect to ice, the contrails can develop into contrail-cirrus that affect the radiative forcing, locally up to an annual average of 1000 mWm-2 over Europe.

  7. 5. Observed Ice Supersaturated Layers over Sweden and Implications for Aviation Induced Contrails over the Baltic Sea

    Magister-uppsats, Uppsala universitet/Luft-, vatten- och landskapslära

    Författare :Elin Björklund; [2011]
    Nyckelord :-;

    Sammanfattning : In the atmosphere vertical extended layers that are in the state of super saturation with respect to ice can appear; these layers have been termed ice-supersaturated layers (ISSL). If an aircraft passes through an ISSL, persistent condensation trails can form. LÄS MER
