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

    University essay from Uppsala universitet/Institutionen för fysik och astronomi

    Author : Derek van Winden; [2024]
    Keywords : 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;

    Abstract :  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. READ MORE

  3. 2. FPGA Based Control of Multiple Electric Machines for Marine Propulsion Systems

    University essay from KTH/Skolan för elektroteknik och datavetenskap (EECS)

    Author : Simon Weideskog; [2024]
    Keywords : FPGA; Field Oriented Control; BLDC; SVPWM; SMO; Electric Drives; Electric Machines; Sliding Mode Observer; Marine Propulsion; Multiple Machines; Boat Motor; Fältorienterad styrning; marin framdrivning; elektriska drivsystem; elmaskiner; flertal maskiner; båtmotor;

    Abstract : This master thesis addresses the control of electric propulsion motors in a marine context. The focus lies mainly on the implementation of field oriented control (FOC) in a field programmable gate array (FPGA). The hypothesis is that FPGAs provide performance advantages over microcontroller-based control solutions by enabling parallel processing. READ MORE

  4. 3. Towards Sustainable Transport: A case study on modal shift for temperature-controlled goods between northern Norway and central Europe

    University essay from Göteborgs universitet/Graduate School

    Author : Love Kristoffersson; Etienne Skowronski; [2023-07-03]
    Keywords : road-rail transport; temperature-controlled goods; cross-border; modal shift; transportation network;

    Abstract : In line with the ambitious sustainability goals set by the European Union to reduce transport emissions, there is a growing interest for sustainable freight transport across Europe. Rail transportation has emerged as a preferred mode of choice for shippers and freight forwarders, given its sustainability advantage of transporting larger volumes on longer distances. READ MORE

  5. 4. Can an alternative cosmovision challenge the market hegemony? : an analysis of article 6.8 in the Paris agreement

    University essay from SLU/Dept. of Urban and Rural Development

    Author : Amanda Björksell; [2023]
    Keywords : climate negotiations; Paris agreement; Buen Vivir; ; Vivir Bien; article 6.8; climate justice; Bolivia; non-market approaches;

    Abstract : A rising global temperature and increased emissions, in combination with the slow progress of the yearly climate negotiations shows that there is something hindering the radical improvement needed to protect both the planet and humanity. The outset for this thesis is to study the UN climate negotiations and the alternative discourse that can question the hegemony. READ MORE

  6. 5. Tribological characterization of a ball bearing subjected to an electric field : Electric drivetrain tribology

    University essay from Luleå tekniska universitet/Institutionen för teknikvetenskap och matematik
