  1. 16. THE MONASTERY HILL: GEOPHYSICAL METHODS FOR DESCRIBING ARCHAEOLOGY AND NEAR-SURFACE GEOLOGY IN LÖDÖSE, SW SWEDEN

    University essay from Göteborgs universitet/Institutionen för geovetenskaper

    Author : Tobias Möhl; Fredrik Andersson; [2021-09-21]
    Keywords : Near-surface geophysics; Ground-penetrating radar; Resistivity; Magnetic gradiometry; 3D modeling; Archaeology; Leached clay; Medieval monastery; Sweden;

    Abstract : Even though Sweden has been one of the leading countries in the development of nearsurface geophysics instrumentation and practices, geophysical surveys in archaeology are not commonly used in Sweden. However, it is becoming increasingly popular, especially the use of ground-penetrating radar and metal detectors. READ MORE

  3. 17. Integration of Borehole, Ground, and Airborne Data to Improve Identification of Areas With Quick Clays in Sweden

    University essay from Uppsala universitet/Geofysik

    Author : Oskar Rydman; [2021]
    Keywords : TEM; tTEM; Quick clay; SkyTEM; ATEM; CPTR; CPTU-R; Landslides; Frastad; TEM; tTEM; Quick clay; SkyTEM; ATEM; CPTR; CPTU-R; Jordskred; Fråstad;

    Abstract : The main focus of the project was the comparison of results from a new towed transientelectromagnetic (tTEM) data set with existing data including airborne transient EM(ATEM), radio magnetotellurics (RMT), cone penetration test with resistivity (CPT-R),geotechnical interpretations and geological observations in a quick clay landslide site atFråstad close to Lilla Edet in south-west Sweden. The tTEM data set was processedand inverted twice in the software Aarhus workbench using different inversion constraintsand settings. READ MORE

  4. 18. Homebuilt reactor design and atomic layer deposition of metal oxide thin films

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

    Author : Pamburayi Mpofu; [2021]
    Keywords : Thin films; atomic layer deposition;

    Abstract : This research thesis covers work done on building an atomic layer deposition (ALD) reactor followed by the development and optimization of an ALD process for indium oxide thin films on crystalline silicon substrates from new precursors using this new homebuilt cost-effective tool. This work describes the design, building and testing of the ALD system using an indium triazenide precursor and water in a novel precursor combination. READ MORE

  5. 19. Direct Sampling of the Pulsed Eddy Current Response From Non-Ferromagnetic Metals

    University essay from Umeå universitet/Institutionen för fysik

    Author : Sara Holmér; [2021]
    Keywords : ;

    Abstract : The non-destructive testing method Pulsed Eddy Current, or PEC, can be used to measure the thickness and resistivity of conducting and non-ferromagnetic materials. In this project I investigated if a gauge at ABB, which uses PEC technology to measure the thickness of aluminium strips in rolling mills, can extract more information about the strip by sampling the direct signal with a higher resolution than before.

  6. 20. Inversion of SkyTEM Data Based on Geophysical Logging Results for Groundwater Exploration in Örebro, Sweden

    University essay from Luleå tekniska universitet/Geovetenskap och miljöteknik

    Author : Andrée Kindlund; [2021]
    Keywords : SkyTEM; hydrogeophysics; geophysical logging; A priori; groundwater exploration;

    Abstract : Declining groundwater tables threatens several municipalities in Sweden which drinking water is collected from. To ensure a sound drinking water supply, the Geological Survey of Sweden has initiated a groundwater exploration plan. READ MORE
