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. Spatialanalys av markgeokemi : Hur utlakningshalter av markgeokemin varierar i Sveriges morän enligt interpolationsmetoder

   Kandidat-uppsats, Umeå universitet/Institutionen för ekologi, miljö och geovetenskap

   Författare :Sara Emilie Hansen Österlund; [2023]
   Nyckelord :interpolations; geographic information system; GIS; geochemistry; till; geology;

   Sammanfattning : The purpose of this study was to evaluate the spatial distribution of geochemistry in Swedish till and whether interpolations could predict unknown values of geochemistry between samples at a national spatial level, Sweden, and a regional, the county of Västerbotten. The information of the spatial distribution of the elements and the interpolations accurateness has several applications. LÄS MER

4. 3. ESTIMATION OF RADIATION EXPOSURE FROM NATURALLY OCCURRING RADIONUCLIDES IN FOOD AND FOODSTUFF

   Master-uppsats,

   Författare :Ida Bengtsson; [2022-01-13]
   Nyckelord :Medical physics; Naturally occurring radionuclides; committed effective dose from ingested radionuclides; Biokinetic models;

   Sammanfattning : Purpose: The main purpose of this study was to provide an estimation of the committed effective dose received by the Swedish population from naturally occurring radionuclides (NORM) in the diet. This study was also aiming to investigate the impact on the committed effective dose due to the new developments in the biokinetic model for Po 210 . LÄS MER

5. 4. Kriging radio environment map construction

   Master-uppsats, Luleå tekniska universitet/Rymdteknik

   Författare :Erik Lundqvist; [2022]
   Nyckelord :Kriging; Radio environment; Statistics; Inverse distance weighting;

   Sammanfattning : With the massive increase in usage of some parts of the electromagnetic spectrum during the last decades, the ability to create real time maps of signal coverage is now more important than ever before. This Masters project is designed to test two different methods of generating such maps with a one second limit to processing time. LÄS MER

7. 5. An Optimization Framework for Elastomer Machine Tools

   Master-uppsats, Lunds universitet/Innovation

   Författare :Love Montan Larsson; [2022]
   Nyckelord :Polyurethane; Elastomer; packaging industry; Design of Experiments; Finite Element Analysis; Response Surface Methodology; multiple linear regression analysis; Additive Manufacturing.; Technology and Engineering;

   Sammanfattning : A framework for optimizing the design of elastomer packaging machine tools, so­ called plunge tools, has been developed and has reached a proof­of­concept state in this thesis. The framework indicates the capability of decreasing prototype expenses and total development time of new plunge tools by roughly three times compared to the existing iterative design methodology.
