  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. Wildfire growth modelling in Sweden - a suitability assessment of available data

    Master-uppsats, Lunds universitet/Institutionen för naturgeografi och ekosystemvetenskap

    Författare :Henrik Hagelin; [2023]
    Nyckelord :Geography; GIS; Geographic Information Science; Physical geography; Prometheus; WiSE-FASS; The 2014 Västmanland wildfire; Wildfire growth modelling; Wildfire suppression support; Wildfire behaviour; MESAN; Earth and Environmental Sciences;

    Sammanfattning : Wildfires are worldwide problems that stress societies by damaging their economies and they cause serious, sometimes fatal, health implications among the populations. In recent years, the rate of wildfire occurrence has increased as the global average temperature has risen. Because of global climate change, this rate is expected to continue rising. LÄS MER

  5. 4. Penetration testing of current smart thermostats : Threat modeling and security evaluation of Shelly TRV and Meross Smart Thermostat

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

    Författare :Adam Lindberg; [2023]
    Nyckelord :IoT penetration testing; Smart thermostat; Ethical hacking; PatrIoT; Cybersecurity; IoT penetrationstestning; Smart termostat; Etisk hackning; PatrIoT; Cybersäkerhet;

    Sammanfattning : As smart homes become increasingly common and concerns over Internet of Things (IoT) security grow, this study delves into the vulnerabilities of smart thermostats. These devices offer convenience but also comes with increased risk of cyber attacks. LÄS MER

  7. 5. Enhancing Comfort and Robustness in Hydronic Radiator Systems through Integration of Body Heat Predictions : A Study on a Novel LPV Controller

    Master-uppsats, KTH/Skolan för industriell teknik och management (ITM)

    Författare :Fahim Pirmohamed; [2023]
    Nyckelord :Energy Efficiency; Hydronic Radiators; Linear Parameter-Varying Control; Gain-Scheduling; Occupancy Detection; Radiated Energy Estimation; Thermostatic Radiator Valves; Smart Heating Systems; Robustness; Energieffektivitet; Vattenburna Element; Linjär Parameterberoende Reglering; Gain-Scheduling; Detektering av Närvaro; Beräkning av Utstrålad Energi; Termostatiska Radiatorventiler; Smarta Värmesystem; Robusthet;

    Sammanfattning : The quest to balance occupant comfort with energy efficiency is a key challenge in the field of heating systems, particularly for hydronic radiators. This study addresses this issue by investigating the integration of body heat predictions into a gain-scheduling controller for a hydronic radiator system. LÄS MER
