5. 4. End-Of-Life Wind Turbines in the EU : An Estimation of the NdFeB-Magnets and Containing Rare Earth Elements in the Anthropogenic Stock of Germany and Denmark

   University essay from Uppsala universitet/Institutionen för geovetenskaper

   Author : Lisa Welzel; [2019]
   Keywords : rare earth elements; neodymium; dysprosium; wind turbines; permanent magnets; recycling; recovery; closing the loop; urban mining; sustainability; sällsynta jordartsmetaller; neodymium; dysprosium; vindturbiner; permanenta magneter; återvinning; cirkulärt system; hållbarhet;

   Abstract : Securing rare earth elements (REE) for a stable supply require sustainable management strategies in Europe due to a missing local primary production and a dependence on China as the main producer of REE. These elements, like neodymium (Nd) and dysprosium (Dy), are contained in permanent magnets (PM) (mostly NdFeB-magnets) in wind turbines. READ MORE

6. 5. High precision detection of multiple rotating objects

   University essay from KTH/Mekatronik

   Author : David Nikolas Alfred Wallén; [2018]
   Keywords : ;

   Abstract : Denna avhandling har skrivits i sammarbete med en Stockholmsbaserat konst- och designstudio vid namn ''Humans since 1982'' som bygger och säljer modern högteknologisk konst till marknader världen över. Studion ville utföra forskning kring att utveckla och implementera ett system som detekterade och beräknade positionen av två roterande oberoende objekt monterade på två stegmotorer via en växellåda.
