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

    University essay from Göteborgs universitet/Institutionen för geovetenskaper

    Author : Torpikay Azizi; [2023-08-18]
    Keywords : 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;

    Abstract : 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. READ MORE

  3. 2. The chemical evolution of the Milky Way: pushing APOGEE to higher precision and accuracy

    University essay from Lunds universitet/Astrofysik; Lunds universitet/Fysiska institutionen

    Author : Erik Fridén; [2023]
    Keywords : Physics and Astronomy;

    Abstract : In the recent decade, a rapid increase in all-sky spectroscopic surveys has occurred, and with it, the wealth of observational data and information on our Galaxy. Consequently, numerous detections of new structures, such as new open clusters, accreted and in-situ components, are discovered. READ MORE

  4. 3. Optical properties of water absorbing textiles for camouflage

    University essay from Linköpings universitet/Institutionen för fysik, kemi och biologi

    Author : Eveline Örtenberg; [2023]
    Keywords : Camouflage; SWIR; Water; Nanocellulose; CNF; Textiles;

    Abstract : Background matching, a form of camouflage, involves species developing patterns and coloration that closely resemble their environment. Humans have utilized camouflage and background matching, particularly in military applications, to reduce detectable characteristics, known as signatures. READ MORE

  5. 4. Use of Satellite Remote Sensing for Detecting Archaeological Features: An Example from Ancient Corinth, Greece

    University essay from Lunds universitet/Institutionen för naturgeografi och ekosystemvetenskap

    Author : Emmanouil Papadakis; [2023]
    Keywords : Geography; GIS; Satellite Remote Sensing; Vegetation Indices; Classification; Archaeology; Earth and Environmental Sciences;

    Abstract : During the last few decades, satellite remote sensing has proven to be an important non-invasive method for archaeological research in order to detect ancient sites and manage existing ones. Archaeologists have tried in the recent past to embed Geographic Information Systems (GIS) and image processing techniques in their research as non-destructive approaches, which can allow a wider perception of archaeological landscapes and predict past behaviors.

  6. 5. Relative vegetation height variation and reflectance of herbaceous-dominated patches in Central Sweden

    University essay from Stockholms universitet/Institutionen för naturgeografi

    Author : Jo Santiago; [2020]
    Keywords : vegetation height; reflectance; plant biodiversity; herbaceous vegetation; MSAVI; coefficient of variation of heights; Height Variation Hypothesis;

    Abstract : Semi-natural landscapes are recognized as suitable habitats for different plant species and provide ecosystem services that contribute to increased plant biodiversity. At the stand level, plant biodiversity is influenced by vegetation structure, of which vegetation height is an important parameter. READ MORE
