  1. 41. Motion tracking for virtual reality using inertial motion sensors

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

    Författare :Max Lindgren; Marcus Olsson; [2023]
    Nyckelord :;

    Sammanfattning : Human motion capture has until recently been dominated by camera-based solutions. With advancements within Micro Electro-Mechanical Systems (MEMS) technology new Inertial Measurement Unit (IMU) based solutions are being explored. This thesis explores the possibility of using IMUs for augmenting motion tracking for Virtual Reality (VR). LÄS MER

  3. 42. Atmospheric Gravity Waves revisited with the EISCAT radar

    Master-uppsats, Uppsala universitet/Institutet för rymdfysik, Uppsalaavdelningen; Uppsala universitet/Institutionen för fysik och astronomi

    Författare :Tatsuya Hirabayashi; [2023]
    Nyckelord :;

    Sammanfattning : It is known that AGWs strongly interact with Traveling Ionospheric Disturbancescalled TIDs (e.g. Kirchengast et al., 1996). LÄS MER

  4. 43. Trajectory Optimisation of a Spacecraft Swarm Maximising Gravitational Signal

    Master-uppsats, KTH/Optimeringslära och systemteori

    Författare :Rasmus Maråk; [2023]
    Nyckelord :Spacecraft Swarms; Trajectory Optimisation; Impulsive Manoeuvres; Evolutionary Algorithms; Polyhedral Gravity Model; Small Body Exploration; Discrete Spherical Grids; Svärmande rymdfarkoster; Banoptimering; Impulsiva manövrar; Evolutionära Algoritmer; Polyhedral gravitationsmodell; Utforksning av små kroppar i solsystemet; Diskreta sfäriska rutnät;

    Sammanfattning : Proper modelling of the gravitational fields of irregularly shaped asteroids and comets is an essential yet challenging part of any spacecraft visit and flyby to these bodies. Accurate density representations provide crucial information for proximity missions, which rely heavily on it to design safe and efficient trajectories. LÄS MER

  5. 44. Gravitational Decoherence in Macroscopic Quantum Systems

    Kandidat-uppsats, Uppsala universitet/Teoretisk fysik

    Författare :Niklas Engelhardt Önne; [2023]
    Nyckelord :decoherence; gravitational decoherence; quantum mechanics; quantum physics; macroscopic quantum mechanics; macroscopic quantum physics; gravity; general relativity; gravitational time dilation; quantum-to-classical transition; nonrelativistic quantum mechanics; quantum gravity; dekoherens; gravitationell dekoherens; kvantmekanik; kvantfysik; makroskopisk kvantmekanik; makroskopisk kvantfysik; gravitation; allmän relativitetsteori; gravitationell tidsdilatation; övergången från kvantfysik till klassisk fysik; ickerelativistisk kvantmekanik; kvantgravitation;

    Sammanfattning : The problem of how quantum mechanics gives rise to classicality has been debated for more than a century. A commonly proposed solution is decoherence, i.e. the gradual decay of superpositions in open quantum systems due to their inevitable interaction with their environment. LÄS MER

  7. 45. Digitalised Combats and Their Impact on Social Sustainability in Kenya and Nigeria

    Master-uppsats, Försvarshögskolan

    Författare :Roland Aszalós; [2023]
    Nyckelord :Africa; digitalisation; digital transformation; combats; social sustainability; terrorism; al-Shabaab; Boko Haram; peacekeeping; securitisation; Centre of Gravity; cyber warfare; cryptocurrency; dark web; social media;

    Sammanfattning : In our era, digital technology is one of the fastest-changing areas. It impacts our private life, well-being, economics, politics and warfare. This essay intends to answer how digital transformation affects combats and state and non-state actors and also how these digitalised combats compromise social sustainability. LÄS MER
