  1. 1. The OpenXO. 3D Printed Modular Exoskeleton Segment

    Master-uppsats, Luleå tekniska universitet/Rymdteknik

    Författare :Árni Þór Þorgerirsson; [2023]
    Nyckelord :Exoskeleton; Open-Source; Fused Filament Fabrication FFF ; Cycloidal Drive; OpenXO; precision fabrication;

    Sammanfattning : Exoskeletons are wearable devices that enhance or supplement the user’s natural abilities. They have been demonstrated to be efective in alleviating pain, reducing work related injuries, improving working conditions, and can play a pivotal role in improving recovery times and recovery outcomes.

  3. 2. Beyond Traditional Tomography: X-ray Multi-projection Imaging for Additive Manufacturing

    Kandidat-uppsats, Lunds universitet/Synkrotronljusfysik; Lunds universitet/Fysiska institutionen

    Författare :Maria Esther Vilar Alvarez; [2023]
    Nyckelord :X-ray tomography; X-ray multiprojection-imaging; deep learning; additive manufacturing; synchrotron radiation; Physics and Astronomy;

    Sammanfattning : The main aim of this bachelor thesis is to push the limits of 3D X-ray imaging by studying the minimum number of projections required to retrieve high-quality reconstructions for additive manufacturing processes. This project first focuses on understanding how X-ray tomography works, by reconstructing additive manufacturing data already obtained (from PSI, TOMCAT beamline) using two standard reconstruction algorithms, GRIDREC and SIRT.

  4. 3. Convection in a spherical shell under rapid rotation: numerical simulations

    Master-uppsats, KTH/Teknisk mekanik

    Författare :Camille Rambert; [2022]
    Nyckelord :convection; rapid rotation; spectral methods; spherical geometry;

    Sammanfattning : A numerical method for solving the buoyancy-driven magneto-convection equations in a rapidly rotating spherical shell is presented. The method is implemented through a FORTRAN 90 program, based on a FORTRAN 66 code written by Hollerbach [International Journal for Numerical Methods in Fluids, 32 (2000)] and partially translated in FORTRAN 90 by Riquier.

  5. 4. Cropping systems with leys : analysis of a long-term experiment in Northern Sweden

    Master-uppsats, SLU/Dept. of Crop Production Ecology

    Författare :Elin Lindén; [2021]
    Nyckelord :yield; yield stability; crop rotation; cropping systems; ley; barley; long-term experiments;

    Sammanfattning : Climate change affects agriculture all over the world and in the Northern hemisphere the change towards warmer temperatures is more rapid than other parts on the planet. As this progresses the need to produce food in a sustainable way and stabilize or increase yields is essential. LÄS MER

  7. 5. Evaluation of the possibility of phytoremediation (using Salix) as a management tool for abandoned sites moderately contaminated with arsenic : a literature review

    Master-uppsats, SLU/Dept. of Soil and Environment

    Författare :Victor Akinwale; [2020]
    Nyckelord :phytostabilization; leaching; solubility and mobility; economic benefits;

    Sammanfattning : The presence of arsenic in soil and water has become an increasing problem in many countries around the world. The exposure of high concentration of arsenic in its inorganic form in natural environment such as soil and water makes it harmful to both humans, wildlife and plants. LÄS MER
