  1. 1. Detecting Lithium Brine in Afghanistan Using Spaceborne Hyperspectral Data

    Master-uppsats, Göteborgs universitet/Institutionen för geovetenskaper

    Författare :Torpikay Azizi; [2023-08-18]
    Nyckelord :PRISMA Hyperspectral data; lithium mineral deposits; lithium brine-rich deposits; Dashti-e- Nawar; boron deposits; Principal Component Analysis PCA ; supervised and unsupervised classification; spectral matching; spectral profile analysis; visible-near-infrared VNIR ; short-wave infrared SWIR Gypsum; Hectorite; Kaolinite; Lepidolite; lithium carbonate; lithium chloride;

    Sammanfattning : The purpose of this thesis is to utilize hyperspectral remote sensing technology for the identification and evaluation of lithium mineral deposits in Afghanistan. Afghanistan boasts unique geological formations with substantial potential for lithium resources beneath its land crust. LÄS MER

  3. 2. A detailed study of auroral fragments

    Master-uppsats, Uppsala universitet/Institutionen för fysik och astronomi; Uppsala universitet/Institutet för rymdfysik, Uppsalaavdelningen

    Författare :Joshua Dreyer; [2019]
    Nyckelord :aurora; fragments; Svalbard; all-sky camera; MSP; ASK; EISCAT;

    Sammanfattning : Aurora occurs in various shapes, one of which is the hitherto unreported phenomenon of auroral fragments. For three periods of occurrence of these fragments their properties were studied in detail during this master’s thesis, using mainly ground-based instrumentation located near Longyearbyen on Svalbard, Norway.

  4. 3. Flygplansdesign

    Kandidat-uppsats, KTH/Skolan för teknikvetenskap (SCI)

    Författare :Rawan Hasan; Amir Khiabani; [2017]
    Nyckelord :;

    Sammanfattning : Syftet med detta projekt är att designa och simulera ett transportflygplan vars specifikationer bestäms av tilltänkt uppdrag. Projektets enda givna krav är att det designade flygplanet ska klara av att transportera förnödenheter från Europa till något land i närheten av ekvatorn utan att förse den med bränsle under färden.

  5. 4. GaSb nanowire transistors with process induced strain

    Master-uppsats, Lunds universitet/Fysiska institutionen; Lunds universitet/Förbränningsfysik

    Författare :Edvin Winqvist; [2017]
    Nyckelord :GaSb; gallium; antimonide; nanowire; transistor; strain; physics; thesis; Physics and Astronomy;

    Sammanfattning : With the constant downscaling of Si transistors reaching its limits, other alternatives have been actively researched the past decades. Group III-V semiconductors are excellent materials with generally high carrier mobilities that can replace Si in transistors. LÄS MER

  7. 5. Concentrations and riverine massflows of geothermal arsenic. : Case study: Jemez River, NM, USA

    Master-uppsats, Stockholms universitet/Institutionen för naturgeografi

    Författare :Lina Hansson; [2016]
    Nyckelord :arsenic; speciation; river discharge; fault;

    Sammanfattning : Geothermal arsenic (As) and its inorganic species transformation in river systems are of global concern, since As has a potential negative impact on human health and ecosystems. Periods of increased precipitation may change As concentrations and As partitioning in streams, due to elevated water tables, increased runoff generation, dilution, and interactions with sediment.
