1. 1. Evaluating the performance of cone crushers under various feeding conditions using DEM and coupled DEM-MBS simulations

   Uppsats för yrkesexamina på avancerad nivå, Luleå tekniska universitet/Institutionen för teknikvetenskap och matematik

   Författare :John Larsson; [2023]
   Nyckelord :Discrete Element Method; DEM; Cone Crusher; Segregation; Co-Simulation; Multi-body Dynamics; MBD;

   Sammanfattning : Cone crushers are used in both the construction and mining industries for the production of aggregates and extraction of ores. Aggregates are used when building for example houses, roads and railways, hence the cone crushers are a vital part of modern society. LÄS MER

3. 2. Research and Analysis of Suspension Dynamics of an Autonomous Bidirectional Road Vehicle

   Master-uppsats, KTH/Väg- och spårfordon samt konceptuell fordonsdesign

   Författare :Isabelle Gürsac; Tsimafei Klimantovich; [2023]
   Nyckelord :Bidirectional vehicle; 4WS; 4WD; suspension angles; kingpin inclination; camber angle; caster angle; toe angle; relative importance; suspension setup; suspension system; drivetrain; efficiency.; Dubbelriktat fordon; fyrhjulsstyrning; fyrhjulsdrift; hjulvinklar; Kingpin-lutningsvinkel; cambervinkel; castervinkel; toevinkel; relativ betydelse; fjädringsinställning; hjulupphängningssystem; drivlina; effektivitet.;

   Sammanfattning : The bidirectionality of road vehicles is a novel research area, which is directly connected with autonomy, efficiency, flexibility and sustainability of transportation. The research in this area is mostly performed with stringent restrictions in corporate secrecy. This fact makes the area publicly unexplored, moreover highly future oriented. LÄS MER

4. 3. Beyond Traditional Tomography: X-ray Multi-projection Imaging for Additive Manufacturing

   Kandidat-uppsats, Lunds universitet/Synkrotronljusfysik; Lunds universitet/Fysiska institutionen

   Författare :Maria Esther Vilar Alvarez; [2023]
   Nyckelord :X-ray tomography; X-ray multiprojection-imaging; deep learning; additive manufacturing; synchrotron radiation; Physics and Astronomy;

   Sammanfattning : The main aim of this bachelor thesis is to push the limits of 3D X-ray imaging by studying the minimum number of projections required to retrieve high-quality reconstructions for additive manufacturing processes. This project first focuses on understanding how X-ray tomography works, by reconstructing additive manufacturing data already obtained (from PSI, TOMCAT beamline) using two standard reconstruction algorithms, GRIDREC and SIRT.

5. 4. A bonded discrete element approach to simulate loading with hydraulic mining excavators

   Uppsats för yrkesexamina på avancerad nivå, Luleå tekniska universitet/Institutionen för teknikvetenskap och matematik

   Författare :Carl Andersson; [2021]
   Nyckelord :DEM; bonded DE; granular material; hydraulic excavator; wear; Archard s wear law; LS-DYNA; simulation;

   Sammanfattning : When operating hydraulic mining excavators the loading equipment is exposed to harsh conditions which lead to extensive wear of the equipment, especially the bucket and bucket teeth. Simulations are used to better understand the wear development and to evaluate new methods to operate excavators more efficiently. LÄS MER

7. 5. Automated pipeline for processing fluorescence calcium imaging microscopy data and electrophysiological measurements from 3D brain organoids

   Master-uppsats, Lunds universitet/Examensarbeten i bioinformatik

   Författare :Mattis Knulst; [2021]
   Nyckelord :Biology and Life Sciences;

   Sammanfattning : Motivation: 3D brain organoids are biological models of human brain development from which a rich body of data can be extracted that allows for insights about neuronal dynamics. Several tools, such as fluorescence calcium imaging microscopy and electrophysiological recordings are being used to assess how 3D brain organoid dynamics recapitulate what is known from the human brain.
