  1. 1. In-Situ Gold Resource Estimation Using Satellite Remote Sensing and Machine Learning in Defunct Tailing Storage Facilities (South Africa)

    Master-uppsats, Uppsala universitet/Institutionen för geovetenskaper

    Författare :Shenelle Agard; [2023]
    Nyckelord :tailings storage facility; critical raw materials; machine learning; mine valorisation;

    Sammanfattning : The mining industry generates billions of tonnes of waste annually, which is often stored in tailings storage facilities (TSF). This waste is generated from the extraction of ore from surface or underground mines, as well as from metallurgical processing and low-grade stockpiles. LÄS MER

  3. 2. Interpolation and visualization of sparse GPR data

    Master-uppsats, Umeå universitet/Institutionen för fysik

    Författare :Rickard Sjödin; [2020]
    Nyckelord :GPR; Ground Penetrating Radar; Interpolation;

    Sammanfattning : Ground Penetrating Radar is a tool for mapping the subsurface in a noninvasive way. The radar instrument transmits electromagnetic waves and records the resulting scattered field. Unfortunately, the data from a survey can be hard to interpret, and this holds extra true for non-experts in the field. The data are also usually in 2. LÄS MER

  4. 3. Statistical Methods for Mineral Models of Drill Cores

    Master-uppsats, KTH/Matematisk statistik

    Författare :Björn Johansson; [2020]
    Nyckelord :Ordinary Kriging; Variograms; Geostatistics; Statistical Methods; Ordinary Kriging; Variogram; Geostatistik; Statistiska Metoder;

    Sammanfattning : In modern mining industry, new resource efficient and climate resilient methods have been gaining traction. Commissioned efforts to improve the efficiency of European mining is further helping us to such goals. Orexplore AB's X-ray technology for analyzing drill cores is currently involved in two such project. LÄS MER

  5. 4. Evaluating spatial mapping using interpolation techniques

    Master-uppsats, Linköpings universitet/Institutionen för datavetenskap

    Författare :Allan Gholmi; [2017]
    Nyckelord :;

    Sammanfattning : In this thesis, the inverse distance weighting, different kriging methods, ordinary least squares and two variants of the geographically weighted regression was used to evaluate the spatial mapping abilities on an observed dataset and a simulated dataset. The two datasets contain the same bioclimatic variable, near-surface air temperature, uniformly distributed over the whole world. LÄS MER

  7. 5. Shopping list generation with machine learning

    Uppsats för yrkesexamina på avancerad nivå, Lunds universitet/Institutionen för datavetenskap

    Författare :Daniel Tykesson; [2017]
    Nyckelord :Machine learning; consumer prediction; consumer behavior; support vector machine; ordinary kriging; Technology and Engineering;

    Sammanfattning : When households do their grocery shopping some sort of shopping list is used to make the shopping easier. The lists contain the groceries that are intended for purchase. These lists can be boring to make and is also not free from errors, so an automated way to generate these lists would be practical. LÄS MER
