    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. Kvalitetsutmaningar i produktionsberedning : En grundorsaksanalys hos Siemens Energy AB

    Kandidat-uppsats, Högskolan Väst/Institutionen för ingenjörsvetenskap

    Sammanfattning : A successful company is characterized by shared values, a clear vision, continuous improvements and everyone’s commitment. By consistently striving to achieve and exceed needs and expectations, quality becomes a cornerstone of long term success. LÄS MER

  4. 3. Circular economy of spare parts and data-driven analytics - “Unlocking Sustainable Value: Analyzing Buyback Policy Circularity Performance in Volvo Group’s Reverse Supply Chain - A Renault Trucks Case Study”

    Master-uppsats, Göteborgs universitet/Graduate School

    Författare :Vladyslav Zahladko; [2023-07-20]
    Nyckelord :closed-loop supply chain; reverse logistics; buyback policy; circular economy; performance measurement; supply chain analytics;

    Sammanfattning : To address the current environmental challenges, companies are steadily shifting from a linear to a circular model in their daily operations. This process implies supplementing the traditional forward logistics with a reverse flow, enabling the reuse, remanufacturing, and recycling of existing products. LÄS MER

  5. 4. Utredning av leveransprecisionen hos Företag X : En analys av in- och utgående logistik, inköp och produktion

    Magister-uppsats, Linnéuniversitetet/Institutionen för management (MAN)

    Författare :Oskar Siggesson; Mattias Hedendahl; [2023]
    Nyckelord :Delivery precision; production planning; ABC XYZ-analysis; classification; cause and effect diagram; Leveransprecision; produktionsplanering; ABC XYZ-analys; klassificering; orsak och verkan-diagram;

    Sammanfattning : Background: The company has had a low outgoing delivery precision for a prolonged period. This creates problems as orders must be prioritized in order to be produced on time and partial deliveries are used to satisfy customers. The origin of the problem is unknown to the company, but there are suspicions that the problems arise in production. LÄS MER

  7. 5. Off-State Stress Effects in AlGaN/GaN HEMTs : Investigation of high-voltage off-state stress impact on performance of and its retention in hybrid-drain ohmic gate AlGaN/GaN HEMTs

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

    Författare :Ivan Krsic; [2023]
    Nyckelord :HEMT; GaN; off-state stress; memory effects; drain leakage current; dynamic RDSon; threshold voltage instabilities; charge redistribution; HEMT; GaN; stress i avslaget tillstånd; minneseffekter; läckströmmen; dynamisk RDSon; instabiliteten hos styrets tröskelspänning; omfördelningen av laddningar;

    Sammanfattning : High electron mobility transistors (HEMTs) realized using AlxGa1-xN/GaN are relatively new technology which is prominent for high-speed and high-power applications. Some of the main problems with this technology were identified as dynamic RDSon, current collapse and threshold voltage instabilities due to the off-state stress. LÄS MER
