  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. Design Investigation of Passive Radiators in Loudspeakers

    Master-uppsats, Lunds universitet/Innovation

    Författare :Fabrice Dufberg; Valter Hamberger; [2024]
    Nyckelord :passive radiator; loudspeaker; speaker tuning; Thiele Small parameters; frequency response; Technology and Engineering;

    Sammanfattning : Passive radiators are components that can be integrated into loudspeakers to amplify the bass frequencies. To ensure good sound quality, the passive radiator, the speaker driver, and the loudspeaker enclosure must all be well-dimensioned and fine-tuned in relation to each other. LÄS MER

  4. 3. Solving the incompressible Navier-Stokes equations in 3-D to model gas flow in a room

    Uppsats för yrkesexamina på avancerad nivå, Uppsala universitet/Avdelningen för beräkningsvetenskap

    Författare :Fredrik Malmström; [2024]
    Nyckelord :;

    Sammanfattning : The thesis proposes to model the flow of gases in a room by solving the incompressible Navier-Stokes equations in three dimensions. The transportationof scalars such as temperature and concentration of CO2 is modeled by solving the advection-diffusion equation, and the effects of temperature on thevelocity is accounted for by employing the Boussinesq approximation.

  5. 4. Integrating Waste Heat from Hydrogen Production Into District Heating

    Master-uppsats, Lunds universitet/Institutionen för energivetenskaper

    Författare :Fawzi Kayali; [2023]
    Nyckelord :Hydrogen; Electrolysis; Waste Heat Recovery; Combined Heat and Power Plant; District Heating; Simulation; Sustainable Heating Systems; Technology and Engineering;

    Sammanfattning : The aim of this research is to explore the feasibility of the integration of waste heat from electrolyzers within a Combined Heat and Power (CHP) plant and district heating (DH) network and suggest a practical setup for integration. With the escalating emphasis on the development of green hydrogen through electrolysis powered by renewable energy, a substantial amount of waste heat is generated, typically left unused. LÄS MER

  7. 5. Elektromagnetisk modellering av Grimeton Radiostations VLF-antenn

    M1-uppsats, Högskolan i Halmstad/Akademin för informationsteknologi

    Författare :Lukas Lindqvist; Shaven Guli; [2023]
    Nyckelord :;

    Sammanfattning : Vid konstruktion av antenner idag används datorbaserade verktyg för att görasimuleringar i utvecklingsskedet för att se till att antennen uppnår eftersträvadprestanda. Denna teknik var inte möjlig att använda under de första årtiondenaav 1900-talet då multipelantennen utvecklades, vilket är antenntypen somanvänds vid Radiostationen i Grimeton. LÄS MER
