  1. 1. 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

  3. 2. Traduire la mémoire : La mémoire du Chambon-sur-Lignon entre 'foreignization' & 'domestication'

    Magister-uppsats, Linnéuniversitetet/Institutionen för språk (SPR)

    Författare :Julia Lindholm; [2023]
    Nyckelord :historical memory; translation strategies; world war two; translation of historical memory; mémoire historique; stratégies de traduction; seconde guerre mondiale; traduction de mémoire historique;

    Sammanfattning : This paper examines how to translate the historical memory of Chambon-sur-Lignon in France, by analyzing the translation procedures used to transfer proper nouns (personal names, place names, names of organizations) and cultural references (historical, theological) from French to Swedish, on a scale between the strategies foreignization and domestication. The analysis is based on our own translation of three source texts from the book La Montagne refuge. LÄS MER

  4. 3. Virtual power lines in the future Swedish power system

    Uppsats för yrkesexamina på avancerad nivå, Lunds universitet/Industriell elektroteknik och automation

    Författare :Simon Hessman; Frida Lundberg; [2023]
    Nyckelord :VPL Virtual Power Line Nordic44 Nordic46 BESS Energy Storage; Technology and Engineering;

    Sammanfattning : The transition towards renewable energy and electrification is expected to accelerate in the coming decades. This change is being studied by several actors, in Sweden most notably by Svenska kraft- nät, the Swedish TSO. LÄS MER

  5. 4. Velocity Control of a Mobile Charger in a Wireless Rechargeable Sensor Network

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

    Författare :Emilia Haltorp; [2023]
    Nyckelord :Wireless Sensor Networks; Mobile Charger; Wireless Energy Transfer; Traveling Salesman Problem; Trådlösa Sensornätverk; Mobil laddare; Trådlös strömöverföring; Handelsresandeprobleme;

    Sammanfattning : Wireless sensor networks (WSN) are one of the most rapidly evolving technical areas right now. They can be used in a lot of different applications, environmental monitoring and health applications being two examples. The sensors can be placed in hazardous and remote environments since there is no need for cabling or manual maintenance. LÄS MER

  7. 5. Model-Observation Comparisons of O+ Concentrations in the Martian Ionosphere

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

    Författare :Chinmaya Nagar; [2023]
    Nyckelord :MAVEN; NGIMS; Martian; Ionosphere; Fehsenfeld; Tenewitz;

    Sammanfattning : A few years ago, the charge-transfer reaction CO2+  +  O ⟶ O+ + CO2 was investigated experimentally for the first time since the study by Fehsenfeld et al., (1970). This new investigation was conducted by Tenewitz et al., (2018). LÄS MER
