  1. 1. Establishing High-Temperature Models for Leakage Current in Gated Lateral Bipolar Junction Transistors

    Uppsats för yrkesexamina på avancerad nivå, Luleå tekniska universitet/Institutionen för teknikvetenskap och matematik

    Författare :Jimmy Atterstig; [2024]
    Nyckelord :Electronics; leakage current; brokaw bandgap; semiconductor physics; gauss-newton;

    Sammanfattning : Power-efficient circuits are a vital step in moving towards a greener future. Battery life can get substantially improved by decreasing the amount of power a circuit needs. Lower power also leads to less excess heat generated. LÄS MER

  3. 2. Study case: The water-cooling effect on floating photovoltaic plants performance

    Master-uppsats, KTH/Energiteknik

    Författare :Alice Dragon; [2024]
    Nyckelord :Solar photovoltaic; Floating photovoltaic; Performance analysis; Thermal loss; Panel Efficiency; Cooling effect; Solceller; Flytande solceller; Prestandaanalys; Termisk förlust; Panelens effektivitet; Kylande effekt;

    Sammanfattning : Floating solar technology is relatively new, and it comes with its own set of challenges and opportunities. This master thesis focuses on understanding how Floating Photovoltaic (FPV) projects perform compared to Ground-Based Photovoltaic (GPV) projects, in specific weather conditions. LÄS MER

  4. 3. Structural analysis of HZO thin film and electrode using X-ray diffraction

    Kandidat-uppsats, Lunds universitet/Synkrotronljusfysik; Lunds universitet/Fysiska institutionen

    Författare :Elliot Winsnes; [2024]
    Nyckelord :HZO; hafnia; hafnium dioxide; zirconium dioxide; ferroelectricity; ferroelectric; synchrotron radiation; X-ray diffraction; Physics and Astronomy;

    Sammanfattning : Since its discovery in 2011, the ferroelectricity of thin films based on HfO2 has been studied intensively. In particular, thin films with a 1:1 ratio of HfO2 and ZrO2 (HZO) has been of great interest. The ferroelectricity arises from a non-centrosymmetric orthorhombic (o) phase of HZO whose prevalence is dependent on the processing conditions. LÄS MER

  5. 4. Predicting inflow and infiltration to wastewater networks based on temperature measurements

    Uppsats för yrkesexamina på avancerad nivå, Uppsala universitet/Institutionen för informationsteknologi

    Författare :Martin Åsell; [2024]
    Nyckelord :Inflow and Infiltration; I I; CNN; Linear regression;

    Sammanfattning : Sewer pipelines are deteriorating due to aging and sub optimal material selections, leading to the infiltration of clean ground and rainfall water into the pipes. It is estimated that a significant portion (up to 40-50%) of the water entering wastewater treatment plants is actually clean infiltrated water. LÄS MER

  7. 5. Greenhouse gas emissions from peat soil thawing in spring : a comparison between fertilized and unfertilized soil

    Master-uppsats, SLU/Dept. of Soil and Environment

    Författare :Fanny Otterlin Karlsson; [2024]
    Nyckelord :agricultural soil; carbon dioxide; freeze-thaw cycles; nitrous oxide; soil temperature; water content;

    Sammanfattning : Peat soils drained for agriculture and forestry contribute to a significant amount of greenhouse gas emissions. Nitrous oxide is a greenhouse gas with high warming potential and agriculture in general accounts for about 70 % of nitrous oxide emissions. LÄS MER
