  1. 16. Attitude Dynamics and Control for the Task Scheduling of Agile Earth Observation Satellites

    University essay from KTH/Lättkonstruktioner, marina system, flyg- och rymdteknik, rörelsemekanik

    Author : Renato Franze; [2023]
    Keywords : Attitude Dynamics; Attitude Control; Earth Observation; Scheduling; Attityddynamik; Attitydkontroll; Jordobservation; Uppgiftsschemaläggning;

    Abstract : This thesis deals with the scheduling problem for a constellation of Earth observation satellites, focusing on modelling the attitude dynamics to assess the tasking capabilities. A target selection algorithm is developed considering the time dependent manoeuvres between targets and the time-dependent value of the observed targets. READ MORE

  3. 17. Blockchain-based delivery command system for satellites

    University essay from Luleå tekniska universitet/Institutionen för system- och rymdteknik

    Author : Catalin Daniel Neagu; [2023]
    Keywords : blockchain; space; satellites; space engineering; blockchain in space industry;

    Abstract : As the commercialization of space continues on a global scale, it is increasingly common to see companies, as well as space agencies, become more and more interested in developing constellations of satellites, mainly for telecommunication and remote sensing missions. While there are multiple issues that arise when operating constellations of medium to large scales, one of the most challenging issue is the distribution of commands and control among satellites.

  4. 18. Identifying Fundamental Characteristics of Shock Nonstationarity using MMS Measurements : Identifying and Distinguishing Non-stationary Behaviour Through the Magnetic Field Gradient in Quasi-perpendicular Shocks

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

    Author : Hannah Wik; [2023]
    Keywords : Space; Space Plasma Physics; Collisionless Shocks; MMS; Non-stationarity; Shock Reformation; Rippling; Bow Shock; Solar Wind; Rymd; Rymdfysik; Kollisionsfria chocker; MMS; Icke-stationär; Reformation; Bogchock; Solvind;

    Abstract : Collisionless shocks are widespread phenomena in the universe, and understanding the mechanisms behind their energy dissipation, with a rare number of collisions between particles, remains a significant unresolved question. The Earth’s bow shock provides an excellent opportunity to study this phenomena in situ. READ MORE

  5. 19. Neuromorphic Medical Image Analysis at the Edge : On-Edge training with the Akida Brainchip

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

    Author : Ebba Bråtman; Lucas Dow; [2023]
    Keywords : ;

    Abstract : Computed Tomography (CT) scans play a crucial role in medical imaging, allowing neuroscientists to identify intracranial pathologies such as haemorrhages and malignant tumours in the brain. This thesis explores the potential of deep learning models as an aid in intracranial pathology detection through medical imaging. READ MORE

  6. 20. Sårskador hos grupphållna gyltor och suggor : en observationsstudie av kommersiella besättningar

    University essay from SLU/Dept. of Animal Environment and Health

    Author : Elvira Chivers Palmqvist; [2023]
    Keywords : gris; grupphållning; agonistiska beteenden; aggressiva beteenden; sår;

    Abstract : Skin lesions are a common problem within group-housed gilts and sows. Since 2013, all EU member states are required to ensure that all gilts and sows are kept in group housing. Pigs used in production in Sweden today originate from the wild boar. Wild boars and production pigs still share many traits. READ MORE
