  1. 1. Predictive Controllers for Load Transportation in Microgravity Environments

    Master-uppsats, KTH/Skolan för elektroteknik och datavetenskap (EECS)

    Författare :Sujet Phodapol; [2023]
    Nyckelord :Model Predictive Control; Decentralized control; Multi-robot systems; Space technology; Modell-prediktiv reglering; Decentraliserad reglering; Multirobotsystem; Rymdteknologi;

    Sammanfattning : Space activities have been increasing dramatically in the past decades. As a result, the number of space debris has also increased significantly. Therefore, it is necessary to clean up and remove them to prevent a collision between space debris and spacecraft. LÄS MER

  3. 2. Chromatin accessibility analysis of spaceflight mouse brains using ArchR

    Master-uppsats, KTH/Genteknologi

    Författare :Raphaël Mauron; [2023]
    Nyckelord :Single nuclei ATAC-sequencing; Space Biology; DNA Chromatin accessibility; Neurodegenerative; ArchR; ATAC-sekvensering av enskilda kärnor; rymdbiologi; tillgänglighet av DNA kromatin ; neurodegenerativa sjukdomar; ArchR;

    Sammanfattning : Mänsklig utforskning av månen och Mars innebär stora utmaningar för människans fysiologi och hälsa på grund av de unika miljöfaktorer som följer av långvariga rymduppdrag. Rymdbiologiska experiment har blivit ett viktigt verktyg för att studera effekterna som mikrogravitation och rymdstrålning har på levande organismer, i syfte att förstå och minska dessa utmaningar.

  4. 3. Analysis and Design of a Microgravity Drop Tower

    Master-uppsats, Luleå tekniska universitet/Rymdteknik

    Författare :Tristan Edwards; [2023]
    Nyckelord :drop tower; microgravity;

    Sammanfattning : A drop tower is a device that produces a microgravity environment by allowing an experiment to free fall for a short period of time, usually less than 10 seconds. Certain types of drop towers are also capable of reproducing the gravitational conditions of other celestial bodies, such as Lunar and Martian gravity. LÄS MER

  5. 4. Preparation of Pancreatic EndoCβH1 cells alone and together with Boundary Cap Neural Crest Stem cells for a microgravity experiment

    Master-uppsats, Uppsala universitet/Institutionen för biologisk grundutbildning

    Författare :SRINIVASAPRASAD RANGASWAMY; [2022]
    Nyckelord :Pancreatic Islets; Neural crest stem cells; space chamber; Survival test for EndoCβH1 cells; 3-D print;

    Sammanfattning : Migrating to Mars is the next exploration of human space missions and adapting to the extreme environment for a long period of time needs to be studied in-prior. Studies on cells in space may promote advancements in our understanding of the human body. LÄS MER

  7. 5. Spatially resolved gene expression profiling of mouse brain tissue to study the impact of spaceflights

    Master-uppsats, KTH/Proteinvetenskap

    Författare :Paula Frieberg; [2021]
    Nyckelord :spaceflight; space biologu; Spatial Transcriptomics; mouse brain tissue; mitochondria;

    Sammanfattning : Since the first human spaceflight in 1961, hundreds of humans have been in space. Microgravity and high radiation are the main spaceflight hazards. The space environment is known to impact several aspects of human health, such as bone density and cognitive performance. LÄS MER
