  1. 1. Ageing process analysis of solar panels in graveyard geostationaryorbit for reusability potential

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

    Author : Robin Drevet; [2024]
    Keywords : space debris; Spacecraft Materials; satellite; Space Sustainability; Space Circularity; Space Manufacturing;

    Abstract : The constant growth of space debris and the associated risks force the space community to find solutions to mitigate them. Today the most advanced solutions to dispose of satellites and rocket stages after the end of mission consists of moving them either into a graveyard orbit or towards an atmospheric re-entry ending in the demise of both spacecraft and its materials.

  3. 2. Riparian plant biodiversity and community composition of ditches and straightened streams : identifying key environmental drivers in a boreal forest setting

    University essay from SLU/Dept. of Forest Ecology and Management

    Author : Rasmus Staaf; [2024]
    Keywords : artificial waterways; riparian zone; novel ecosystems; ; forestry; ditch network maintenance; species richness; hill-diversity; drainage ditches; coarse woody debris; ditch cleaning; ecology;

    Abstract : Modified ecosystems are typically seen as degraded and having no ecological value. In many cases, the modification of the ecosystem was done more than 100 years ago and may have had time to recover and become a refugia for species that were once more common in the landscape.

  4. 3. Trädplantering i den hårdgjorda staden : utmaningar och lösningsalternativ

    University essay from SLU/Dept. of Landscape Architecture, Planning and Management (from 130101)

    Author : Ingela Carlgren; [2024]
    Keywords : gatuträd; urbana träd; trädplantering; gatumiljö; urban jord; kompaktering; skelettjord; makadamsubstrat; rotceller; suspended pavement;

    Abstract : Träd är viktiga delar av våra städer. De bidrar med många ekosystemtjänster, som klimatreglering, dagvattenhantering och positiva hälsoeffekter. De är också viktiga identitetsskapande element. READ MORE

  5. 4. Mängden död ved i värdekärnor i Söderåsens nationalpark

    University essay from SLU/Southern Swedish Forest Research Centre

    Author : Gustav Thurell; [2024]
    Keywords : volym död ved; stående död ved; liggande död ved; bokskog; nedbrytningsgrad; värdekärna;

    Abstract : There is a lack of knowledge about the development of the dead wood in former production beech (Fagus sylvatica) forests that have been protected. The present study has been carried out in Söderåsen National Park to compare the distribution of dead wood in relatively unaffected beech forests that have been protected for a long time (A-value cores) and older, previously managed beech forest that has only been protected for 20-30 years (B-value cores).

  6. 5. Deep Learning Model Deployment for Spaceborne Reconfigurable Hardware : A flexible acceleration approach

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

    Author : Javier Ferre Martin; [2023]
    Keywords : Space Situational Awareness; Deep Learning; Convolutional Neural Networks; FieldProgrammable Gate Arrays; System-On-Chip; Computer Vision; Dynamic Partial Reconfiguration; High-Level Synthesis; Rymdsituationstänksamhet; Djupinlärning; Konvolutionsnätverk; Omkonfigurerbara Field-Programmable Gate Arrays FPGAs ; System-On-Chip SoC ; Datorseende; Dynamisk partiell omkonfigurering; Högnivåsyntes.;

    Abstract : Space debris and space situational awareness (SSA) have become growing concerns for national security and the sustainability of space operations, where timely detection and tracking of space objects is critical in preventing collision events. Traditional computer-vision algorithms have been used extensively to solve detection and tracking problems in flight, but recently deep learning approaches have seen widespread adoption in non-space related applications for their high accuracy.
