  1. 1. Juice/JDC ion measurement perturbations caused by spacecraft charging in the solar wind and Earth’s magnetosheath

    Master-uppsats, Uppsala universitet/Institutionen för fysik och astronomi

    Författare :Derek van Winden; [2024]
    Nyckelord :Juice; Jupiter Icy Moons Explorer; JDC; Jovian plasma Dynamics and Composition analyzer; Particle Environment Package; PEP; Jupiter; Ganymede; Callisto; Europa; solar wind; magnetosheath; spacecraft charging; Spacecraft Plasma Interaction Software; SPIS; charging; plasma; measurement perturbations; perturbation; distortion; particle detector; Institutet för Rymdfysik; IRF; Dublin Institute for Advanced Studies; DIAS; European Space Agency; ESA;

    Sammanfattning :  In July 2031, a new chapter in the exploration of the Jovian system will begin with the arrival of the Jupiter Icy Moons Explorer (Juice) at Jupiter. Launched on April 14 2024 as part of ESA’s Cosmic Vision programme, the mission aims to study Jupiter and its icy Galilean moons Callisto, Europa, and Ganymede. LÄS MER

  3. 2. Oscillations in a complex sunspot: From theory to data

    Master-uppsats, Luleå tekniska universitet/Institutionen för system- och rymdteknik

    Författare :Femke Kranenbarg; [2024]
    Nyckelord :;

    Sammanfattning : Sunspot oscillations, intricate three-dimensional wave-like motions in the solar atmosphere, result from the complex interplay between plasma and magnetic fields. This study delves into the behaviour of these oscillations, exploring their simultaneous excitation and evaluating their impact on solar phenomena like coronal heating, energy transport, and solar flares.

  4. 3. N-body simulations of exoplanets and their moons

    Master-uppsats, Lunds universitet/Astrofysik; Lunds universitet/Fysiska institutionen

    Författare :Lydia Schollmeier; [2024]
    Nyckelord :Physics and Astronomy;

    Sammanfattning : The planet-planet interactions in a many-planet system cannot be analytically calculated. Instead, they have to be investigated by using an N-body simulation. I discuss three questions about the N-body interactions in planetary systems: The first two are on the system 55 Cnc, a system with five known planets around a K-type star. LÄS MER

  5. 4. Direct solar dryer

    Kandidat-uppsats, Lunds universitet/Institutionen för energivetenskaper

    Författare :Jamyang Dorji; Lungten Lungten; [2023]
    Nyckelord :Open air drying; Thermocouple; Air circulation; Sustainable farming; Drying Efficiency; Drying Chamber; Airflow; Technology and Engineering;

    Sammanfattning : The study presents the design, construction, and performance evaluation of a direct solar dryer with a focus on enhancing the post-harvest preservation of fruits. The increasing demand for the dry fruits in both the local and export markets demand effective and environmentally friendly drying methods. LÄS MER

  7. 5. SHADING ANALYSIS OF AGRIVOLTAIC SYSTEMS : The shading’s effect on lettuce and potato from elevated agrivoltaic system in Sweden

    Master-uppsats, Mälardalens högskola/Framtidens energi

    Författare :Komail Farid; Ahmad Guleed; [2023]
    Nyckelord :photosynthetically active radiation; agrivoltaic system; elevated system; crop yield; agriculture; shade tolerance crop; shading factor; PVsyst;

    Sammanfattning : The world is progressing towards a more sustainable society, where renewable energy sources, including solar energy, play a crucial role. This study aims to address the conflict between agriculture and energy production by exploring the installation of solar panels on farmland. LÄS MER
