    Författare :Emil Kari; [2024]
    Nyckelord :Time series analysis; Navigation system; Underground mines; Post-analysis;

    Sammanfattning : This project aims to develop a simulator for generating realistic data from vehicles operating in underground mines, encompassing positional data and sensor values of the velocity and angle. The project addresses the challenge of analyzing the Hybrid Positioning algorithm within Mobilaris Onboard, a navigation system for underground mines. LÄS MER

  3. 2. If Trees Could Talk - Dendrochemistry, a Promising Method for Understanding Pollution History

    Master-uppsats, Göteborgs universitet/Institutionen för geovetenskaper

    Författare :Jonatan Uusitalo; [2023-08-17]
    Nyckelord :;

    Sammanfattning : Heavy metal pollution presents a significant environmental challenge in the Anthropocene era, and understanding pollution history is crucial to address historical pollution and implementing effective mitigation measures. This study stands among a few comprehensive dendrochemical investigations that utilized an extensive dataset and energy dispersive X-ray fluorescence (EDXRF) technique to reconstruct the contamination history of As, Cd, Cu, Ni, Pb, and Zn, with a focus on Cu.
