  1. 1. Enhancement of a Power Line Information System by Combining BIM and LiDAR Data

    University essay from KTH/Lantmäteri – fastighetsvetenskap och geodesi

    Author : Daniel Wollberg; [2024]
    Keywords : GIS; BIM; FME; CloudCompare; GIS; BIM; FME; CloudCompare;

    Abstract : With the great ongoing energy transition in Sweden, Svenska Kraftnät (SVK) sees a huge need for investment in the Swedish transmission network and supporting IT- systems.  SVK has a great amount of collected laser data over the electric power transmission network however this data does not contain any semantic attribution that can be analyzed on broader information systems.

  3. 2. 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

  4. 3. Unconditional cash transfers to single mothers effective for child education? – Using a historical policy experiment

    University essay from Stockholms universitet/Företagsekonomiska institutionen

    Author : Linnea Karlsson; [2023]
    Keywords : Unconditional cash transfers; needs-based cash grants; welfare targeting; human capital development accumulation; skill formation technology; regression kink design;

    Abstract : In this thesis, I examine whether unconditional cash transfers to poor femaleheaded households have an effect on children’s educational attainment. Using a historical Swedish child allowance policy that targeted unconditional cash transfers to widow mothers with an income below a poverty threshold, I lay out a credible identification strategy, to test the hypothesis with a regression kink design.

  5. 4. The quest for a classical bulge - a study of kinematics, abundances, and ages using microlensed dwarf stars and Gaia

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

    Author : Calum Kvernes Macpherson; [2023]
    Keywords : Bulge; Milky Way; Kinematics; Galpy; Dwarf Stars; Physics and Astronomy;

    Abstract : Context: We present an kinematical analysis of 90 F and G type dwarf, turn-off, and subgiant stars in the Galactic bulge. These stars were observed with high-resolution spectrographs during gravitational microlensing events This allowed for their ages, abundances, and radial velocities to be ascertained while they were significantly brighter.
