  1. 16. Comparison of Magnetic-Susceptibility Models From UAV-borne and Ground Measurements in Enåsen Area, Sweden

    Kandidat-uppsats, Uppsala universitet/Institutionen för geovetenskaper

    Författare :Clara Sjödin; [2022]
    Nyckelord :magnetic susceptibility; Enåsen area; UAV survey; magnetic anomalies; Potent; magnetisk susceptibilitet; Enåsen; drönare; magnetiska anomalier; Potent;

    Sammanfattning : Mapping anomalies in the Earth’s magnetic field is one method used in applied geophysics, for exploring buried structures and objects. Magnetic surveys can be ground-based or made airborne, onboard airplanes, helicopters, or unmanned aerial vehicles (UAV), also known as drones. LÄS MER

  3. 17. Installation of cables for monitoring purposes in the ground by using Horizontal Directional Drilling

    Uppsats för yrkesexamina på avancerad nivå, Lunds universitet/Teknisk geologi; Lunds universitet/Väg- och vattenbyggnad (CI)

    Författare :Eduardo Garcia Cañas; [2022]
    Nyckelord :HDD; Earth Embankment Dam; Resistivity; ERT; IP; Technology and Engineering;

    Sammanfattning : The median age for Swedish earth embankment dams is about 60 years. Due to its longevity, one of the major concerns is the internal erosion causing increased seepage through the dam, which ultimately may increases the risk for dam failure. To meet this challenge, there is a need for improved monitoring methods. LÄS MER

  4. 18. Niobium Ohmic Contacts for Cryogenic Indium Phosphide High-Electron-Mobility Transistors

    Master-uppsats, KTH/Tillämpad fysik

    Författare :Linnéa Bendrot; [2022]
    Nyckelord :Ohmic contacts; high-electron-mobility transistor; InP; Nb films; cryogenic electronics; low-noise amplifier; quantum computing; transfer length method; superconductivity; contact barrier resistance; Ohmska kontakter; högelektronmobilitetstransistorer; indiumfosfid; niob; tunnfilm; kryogen elektronik; lågbrusförstärkare; kvantdatorer; Transfer Length-metod; supraledning; kontakt- barriärresistans;

    Sammanfattning : Ohmic contacts are crucial components in semiconductor devices such as transistors and diodes, and lowering their contact resistance is an important factor in device performance enhancement. This is especially important for low-noise amplifiers (LNAs) where device noise temperature decreases both directly and indirectly with decreasing contact resistance. LÄS MER

  5. 19. Design of 3D-Printed Components : Resistances, Strain Gauges and Touch sensors

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

    Författare :Joar Forsberg; [2022]
    Nyckelord :3D-printing; FFF; Conductive PLA; Strain Gauge; Touch sensor; 3D-printing; FFF; Konduktiv PLA; Töjningsgivare; Vidröringssensor;

    Sammanfattning : Additive manufacturing has recently become an increasingly available, affordable, and versatile technology for industry and enthusiasts alike. One opportunity that this provides is using conductive filament to print electronic sensors and components. LÄS MER

  7. 20. Magnetron sputtering of transparent conducting tungsten doped indium oxide

    Uppsats för yrkesexamina på avancerad nivå, Uppsala universitet/Solcellsteknik

    Författare :Erica Evertsson; [2022]
    Nyckelord :sputtering; indium; TCO; tungsten; thin film; solar cell; IOW;

    Sammanfattning : In thin film solar cells there is a front contact layer called TCO, transparent conducting oxide. This layer requires high conductivity and high transmittance. LÄS MER
