  1. 1. Risk Assessment for Space Debris Collisions

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

    Author : Kenny Andersson; [2023]
    Keywords : space debris; NASA standard breakup model; satellite fragmentations; satellite fragmentation modelling; space surveillance and tracking; ESA MASTER; collision risk; risk assessment; space situational awareness; rymdskrot; NASA standard breakup model; satellitfragmentering; modellering av satellitfragmentering; inmätning och övervakning av rymdobjekt; ESA MASTER; kollisionsrisk; riskbedömning; rymdlägesbild;

    Abstract : The increasing reliance on space infrastructure and its rapid expansion necessitate the development and enhancement of tools for space debris and fragmentation research. Accurate prediction of the risks associated with satellite fragmentation requires comprehensive understanding of the dynamics involved. READ MORE

  3. 2. Using satellite data to calculate entropy of electrons at collisionless shocks

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

    Author : Sofie Berglund; Alice Wallner; [2022]
    Keywords : entropy; electrons; plasma; Earth’s bow shock; magnetic field; collisionless shock; plasma beta; Alfv´en Mach number; MMS; NASA; satellite; IRF;

    Abstract : The solar wind is a supersonic flow of protons and electrons emitted in all directions from the sun. As the supersonic solar wind encounters Earth’s magnetic field, it creates the Earth’s bow shock, which increases the kinetic entropy of electrons passing through it. READ MORE

  4. 3. Critical perspectives: North Sea offshore wind farms. : Oral histories, aesthetics and selected legal frameworks relating to the North Sea.

    University essay from Uppsala universitet/Institutionen för arkeologi och antik historia

    Author : Joanne Moss; [2021]
    Keywords : Aesthetics; Coastal; Decay; Decommission; Development permission; European Landscape Convention; Fluid dynamics; Horizon; Industrial; Judicial review; Marine management; Maunsell; Monopile; NASA; North Sea; Offshore; Oral history; OSPAR; Scotland; Scour; Sealand; Sea plumes; Seascape; Sediment; SPM; Suspended particulate matter; Transience; Trawler; Turbine; United Kingdom; Wind farm.;

    Abstract : The study is developed from five in-depth interviews with individuals from different walks of life who have interacted significantly with the North Sea. The study discusses change in the North Sea specifically in the development of fixed turbine wind farms and their physical and aesthetic effects. READ MORE

  5. 4. Analysis of the Stratospheric Aerosol Load After the 2019 Raikoke Eruption

    University essay from Lunds universitet/Kärnfysik; Lunds universitet/Fysiska institutionen

    Author : Felicia Carlborg; [2021]
    Keywords : Volcanic Climate Impact; Raikoke; CALIPSO; Satellite; Stratospheric Aerosols; Radiative Forcing; Aerosol Optical Depth; Physics and Astronomy;

    Abstract : The stratospheric aerosol load after the eruption of Raikoke in 2019 have been analysed with satellite data from the CALIPSO satellite. The goal was to see how much the stratospheric aerosol load increased due to the Brewer Dobson circulation, and further, how this affected the stratospheric aerosol optical depth (AOD), and the corresponding radiative forcing (RF).

  6. 5. A remote-sensing approach to studying drought resistance in Swedish old-growth and production forests

    University essay from Lunds universitet/Institutionen för naturgeografi och ekosystemvetenskap

    Author : Julika Wolf; [2020]
    Keywords : Physical Geography and Ecosystem Analysis; drought impacts; old-growth forests; forest management; remote sensing; Earth and Environmental Sciences;

    Abstract : Boreal forest ecosystems are predicted to experience hotter and drier summers due to climate change, leading to more frequently reduced soil water availability and an increased risk of droughts, as was already the case in Northern Europe during the severe summer drought of 2018. Prolonged water stress in forest ecosystems can lead to impacts ranging from reduced photosynthesis to forest dieback. READ MORE
