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

   University essay from Uppsala universitet/Institutionen för geovetenskaper

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

   Abstract : 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. READ MORE

   Keywords : geological characterization; analytical techniques; LIBS; ME-XRT; SEM; element maps; SEM-EDS; secondary electrons; rock samples; automated ore microscopy; SEM-Zeiss Merlin; element weight percentages; element oxide percentages; scanning techniques; analytical methods; laser induced breakdown spectrometry; multi energy x-ray transmission; scanning electron microscope; carbon coating; mineralogical classification; element composition; rock chemistry; rock chemical composition;

   Abstract : One of the major challenges in earth sciences and mineral exploration has been to determine with high accuracy and at a fast rate the elemental composition as well as the general chemistry of a rock sample. Many analytical techniques e.g. READ MORE

4. 3. Vibration-Based Terrain Classification for an Autonomous Truck

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

   Author : Lucas Lovén; [2022]
   Keywords : Autonomous vehicles; machine learning; surface identification; obstacle identification; signal processing; time series classification; Autonoma fordon; maskininlärning; detektering av underlag; detektering av hinder; signalhantering; tidsserie klassifiering;

   Abstract : This thesis is focused on developing vibration based terrain classification for an autonomous mining truck. The goal is to classify between good and bad gravel roads as well as good and bad asphalt roads. Current literature within vibration based terrain classification has been focused to a great extent on smaller research vehicles. READ MORE

5. 4. Performance Analysis of Environmentally Adaptable Grease in Large open gears

   University essay from Luleå tekniska universitet/Institutionen för teknikvetenskap och matematik

   Author : Victor Ogunmoye; [2022]
   Keywords : Grease; Large open gears; tribology; lubrication; wear; friction; Twin disc; Material surface;

   Abstract : Environmentally adaptable grease (EAG) lubricants are essential in applications with loss lubrication due to their biodegradable nature. This is because the lubricants could be expelled into the environment during usage in some applications e.g., marine and mining applications. READ MORE

6. 5. Life Cycle Assessment of typical projects of the distribution power network : Assessment, Improvement & Recommendations

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

   Author : Hugo Serres; [2022]
   Keywords : Life cycle assessment; GHG emissions; power infrastructures; Livscykelanalys; växthusgasutsläpp; energiinfrastrukturer;

   Abstract : The carbon footprint of the power generation is studied for more than 30 years now. In order to curb GHG emissions, politics, industrials and consumers tend to take action to reduce the carbon intensity of the electricity mix, spread electrification and enhance usage efficiency.
