  1. 11. Identification and strength classification of weakness zones in the Garpenberg mine based on measurement while drilling (MWD)

    Master-uppsats, Luleå tekniska universitet/Geoteknologi

    Författare :Ioannis Peroulakis; [2022]
    Nyckelord :Drilling; MWD; Garpenberg; Mining; Geotechnics;

    Sammanfattning : Boliden’s Garpenberg mine produces Zn-Pb-Ag(Cu-Au) using a sublevel stoping with pastefill mining method. The orebody is strongly affected by the existence of weakness zones mainly consisting of Talc Schist and Phlogopite Schist which affect the design, planning and production of the stope. LÄS MER

  3. 12. Effekter av upprepad belastning på jorddeformation och stress : fältförsök med upprepad körning i kombination med olika hjullaster på en mellanlera utanför Uppsala

    Uppsats för yrkesexamina på avancerad nivå, SLU/Dept. of Soil and Environment

    Författare :Albin Hidén; [2022]
    Nyckelord :Markfysik; markpackning; tonkm;

    Sammanfattning : Den strukturrationalisering som pågår inom lantbruket har lett till att maskinerna som används blir större och tyngre. Samtidigt medför högre avkastningskrav att fler åtgärder i vissa fall görs och att de görs under mindre gynnsamma förhållanden. LÄS MER

  4. 13. LÖDÖSEHUS: GEOPHYSICAL METHODS FOR DESCRIBING ARCHAEOLOGY AND NEAR-SURFACE GEOLOGY AT THE SITE OF A MEDIEVAL CASTLE IN LÖDÖSE, SW SWEDEN

    Master-uppsats, Göteborgs universitet/Institutionen för geovetenskaper

    Författare :Fredrik Andersson; Tobias Möhl; [2021-09-21]
    Nyckelord :Near-surface geophysics; Ground-penetrating radar; Resistivity; Induced Polarization; Archaeology; Leached clay; Medieval castle; Lödösehus; Lödöse; Sweden;

    Sammanfattning : Near-surface geophysics is a well established method for mapping the geological conditions in the subsurface. The use of geophysics is also a commonly used method in archaeological surveys, although traditionally not as much in Sweden. LÄS MER

  5. 14. Venous Component Separation From a Pulse Oximeter Signal using Blind Source Separation with Ultrasound Imaging as Reference

    Master-uppsats, Lunds universitet/Avdelningen för Biomedicinsk teknik

    Författare :Björn Walter; Stefan Piiroinen; [2021]
    Nyckelord :Photoplethysmogram; PPG; Ultrasound; Blind Source Separation; PCA; SOBI; venous component; Technology and Engineering;

    Sammanfattning : Intradialytic hypotension (IDH) is a major drawback of haemodialysis and occurs in more than every fifth dialysis treatment. There is a need for real-time measurement, with an ability to detect IDH before it occurs. Photoplethysmography (PPG) may provide sufficient information about hemodynamic status to prevent IDH.

  7. 15. Energy storage technologies : A comparative techno-economic analysis with focus on economic value to the customer

    Master-uppsats, KTH/Skolan för industriell teknik och management (ITM)

    Författare :IVA PAPIC; [2021]
    Nyckelord :;

    Sammanfattning : As the global renewable energy penetration increases, energy storage technologies are being rapidly deployed to compensate for the intermittency and non-dispatchability of variable energy resources. Storage solutions play a crucial role in providing reliability and flexibility, but their growth is subject to a number of barriers. LÄS MER
