  1. 1. Electrical Propulsion System Design of a Blended Wing Body UAV

    Kandidat-uppsats, KTH/Skolan för teknikvetenskap (SCI)

    Författare :Kevin Azad; Felix Fungula; [2022]
    Nyckelord :Aerospace; Aviation; Blended Wing Body; Electrical; Green Raven; Propeller; Propulsion; UAV;

    Sammanfattning : The conventional tube-and-wing aircraft has been around since the 1950s, with little to no innovative progress being made towards redesigning the conventional aircraft. The blended wing body (BWB) shape fuses the wing of the aircraft with the fuselage increasing structural strength while also increasing potential surface area to create lift, making it more efficient than conventional wing shapes.

  3. 2. Global Cultures – Critical Zone Observatories of Everyday Objects : (A Global Environmental History of Yogurt)

    Master-uppsats, Uppsala universitet/Institutionen för arkeologi och antik historia

    Författare :Leni Charbonneau; [2022]
    Nyckelord :yogurt; biofilm; critical zone observatory; microbiopolitics; probiotic; microbial biodiversity; new materialism; OOO;

    Sammanfattning : This study turns to what is for many an everyday item – yogurt – as a critical zone observatory, a synergistic, place-based laboratory which aims to integrate heterogenous representations of planetary phenomena as they are registered at a common surface. Yogurt has an impressive cultural endurance largely derived from its prominence in various paradigms of health. LÄS MER

  4. 3. Development and tests of SONAR array for underwater communication

    Master-uppsats, KTH/Marina system

    Författare :Marcus Hellman; [2020]
    Nyckelord :;

    Sammanfattning : Water covers about 70 % of Earth’s surface. Most of the water is located in the ocean’s, which have an average depth of almost 3700 meters. This implies that there is a multitude of phenomena to investigate and discover. But due to human limitations other methods and tools need to be considered in order to investigate the depths.

  5. 4. Continuous Time Fatigue Modelling for Non-proportional Loading

    Master-uppsats, Linköpings universitet/Mekanik och hållfasthetslära

    Författare :Sajjan Gundmi Satish; [2019]
    Nyckelord :Multiaxial Fatigue Loading; Fatigue Analysis; Continuous Time fatigue model; Endurance Surface; Rainflow Counting; Cyclic loading; Cycle Counting; Damage Evolution; High-cycle fatigue; Non-proportional loading;

    Sammanfattning : Fatigue analysis is a critical stage in the design of any structural component. Typically fatigue is analysed during post-processing, but as the size of the analysed component increases, the amount of data stored for the analysis increases simultaneously. LÄS MER

  7. 5. Neuron cell survival on positively charged surface bound gold nanoparticles over gold and silicon substrate

    Master-uppsats, KTH/Skolan för informations- och kommunikationsteknik (ICT)

    Författare :Nabeel Aslam; [2011]
    Nyckelord :;

    Sammanfattning : The attachment of cells onto solid surfaces is a fundamental pedestal in the field of biosensors and biochips development. In this work we investigate the adhesion and survival of rat cortical neurons on positively charged surface. LÄS MER
