  1. 1. A comparison of 2D and 3D resistivity surveys for 3D inversion imaging

    Master-uppsats, KTH/Hållbar utveckling, miljövetenskap och teknik

    Författare :Julia Cavell; [2022]
    Nyckelord :;

    Sammanfattning : Following study focuses on electrical resistivity surveying and how it can be used as an exploration method to increase knowledge of subsurface structures. Future scenarios with increasing population and rapid urbani-zation, put high demands on reliable infrastructure; safe foundations, un-derground structures, environmental safety and access to resources.

  3. 2. Homebuilt reactor design and atomic layer deposition of metal oxide thin films

    Master-uppsats, Linköpings universitet/Institutionen för fysik, kemi och biologi

    Författare :Pamburayi Mpofu; [2021]
    Nyckelord :Thin films; atomic layer deposition;

    Sammanfattning : 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. LÄS MER

  4. 3. Interpretation of geophysical and geochemical data in a 3D geological model construction of a contaminated site

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

    Författare :Haoyu Wei; [2018]
    Nyckelord :Halogenated hydrocarbon; Geophysics; DCIP; GeoScene3D; Groundwater chemistry; Earth and Environmental Sciences; Technology and Engineering;

    Sammanfattning : The Alingsås dry-cleaning facility is one of the heavily halogenated hydrocarbon contaminated sites in Sweden. The source of contamination dates back to the 1970s when a large scale tetrachloroethylene leakage outbroke inside the dry-cleaning building. LÄS MER

  5. 4. 2D Reflection Seismic Imaging at a Quick-clay Landslide Site, in Southwest Sweden

    Master-uppsats, Uppsala universitet/Geofysik

    Författare :Muhammad Umar Saleem; [2012]
    Nyckelord :;

    Sammanfattning : Results from a series of 2D high resolution reflection seismic profiles collected at a quick-clay landslide site are presented. This study is a part of the “Integration of geophysical, hydrogeological and geotechnical methods to aid monitoring landslide in Nordic countries” project, sponsored by the (Geoscientists Without Borders) program of Society of Exploration Geophysicists (SEG).

  7. 5. Geofysiska mätmetoder för prospektering till ballastmaterial

    Magister-uppsats, Lunds universitet/Geologiska institutionen

    Författare :Erik Bohlin; Ludvig Landen; [2008]
    Nyckelord :prospektering; ballastmaterial; LosAngeles test; microDeval test; kulkvarnstest; resistivitet; IP; normaliserad IP; refraktionseismik; tomografi; geofysik; geologi; aggregate prospecting; electrical resistivity imaging; induced polarization; normalized induced polarization; refraction seismics; tomography; studded tyres test; geophysics; geology; Earth and Environmental Sciences;

    Sammanfattning : The Swedish rock-mass industry is currently in a transition period because new rules and regulations strongly limit the possibility to use naturally sorted aggregates for construction and concrete purposes. Furthermore, research and development within the industry is more oriented towards crushed bedrock aggregates. LÄS MER
