1. 1. Detecting illegal gold mining sites in the Amazon forest : Using Deep Learning to Classify Satellites Images

   University essay from KTH/Skolan för elektroteknik och datavetenskap (EECS)

   Author : Nathan Labbe; [2021]
   Keywords : Deep Learning; Image Classification; Image Segmentation; Environmental Monitoring; Illegal Gold Mines Detection; Djupinlärning; bildklassificering; bildsegmentering; miljöövervakning; upptäckt av illegala guldgruvor;

   Abstract : Illegal gold mining in the Amazon forest has increased dramatically since 2005 with the rise in the price of gold. The use of chemicals such as mercury, which facilitate the gold extraction, increases the toxicity of the soil and can enter the food chain, leading to health problems for the inhabitants, and causes the environmental scourge we know today.

3. 2. Classication framework formonitoring calibration ofautonomous waist-actuated minevehicles

   University essay from Örebro universitet/Institutionen för naturvetenskap och teknik

   Author : Per Landström; John Sandström; [2020]
   Keywords : SVM; NDT; machine learning; scan matching; hinge angle sensor; calibration detection;

   Abstract : For autonomous mine vehicles that perform the ”load-haul-dump” (LHD) cycle to operate properly, calibration of the sensors they rely on is crucial. The LHD cycle refers to a vehicle that loads material, hauls the material along a route and dumps it in an extraction point. READ MORE

4. 3. Model based pulse shaping for detection of gamma rays

   University essay from Luleå tekniska universitet/Institutionen för system- och rymdteknik

   Author : Fredrik Ödmark; [2017]
   Keywords : pulse shaping; FWHM; CR-RC; electric noise model; analyse drill samples; gamma ray detector; matched filter; custom filter; clustering;

   Abstract : To analyse drill samples in a mine, a scanner that uses a gamma ray detector can be used. The scanner can analyse the drill sample to quickly see the elements present in the sample without destroying it. READ MORE

5. 4. Defining The Geochemical Footprint For Gold Mineralisation Around Birthday Reef.Reefton Goldfield, New Zealand

   University essay from Stockholms universitet/Institutionen för geologiska vetenskaper

   Author : Jonathan Hamisi; [2016]
   Keywords : Orogenic gold; hydrothermal alteration; Reefton; mass changes; geochemical footprint; vectors; exploration; Blackwater;

   Abstract : Abstract Orogenic gold deposits from the Reefton goldfield in New Zealand hosted in Ordovician metasediments of the Greenland group have produce 67 tons of gold before 1951. The Blackwater mine in Waiuta account for about 1/3 of the gold production at Reefton prior 1951. READ MORE

6. 5. School Shooting : Threat Detection and Classification in Textual Leakage
