  1. 11. Simulation model refinement for Steer and Brake by Wire System : From Simulation Model to Hardware in the Loop

    Master-uppsats, Linköpings universitet/Fluida och mekatroniska system

    Författare :Jeff Risi; Chandan Veera; [2023]
    Nyckelord :Steer-by-Wire; Brake-by-Wire; Real Time model; Hardware-in-the-loop; Mining machine; Fluid Power; Hydraulics; FLUMES;

    Sammanfattning : Simulation tools have progressed largely and in modern times they are commonly usedby engineers to design and simulate machines or part of machines before building and deploying them in the field. The field of Hardware-in-the-loop (HIL) is gaining significant interest among companies as they strive to enhance product safety and reliability simul-taneously reducing testing costs and accelerated development speed.

  3. 12. Teachers’ Perception of Factors Delaying Evacuation of School Children

    Kandidat-uppsats, Lunds universitet/Avdelningen för Brandteknik

    Författare :Rikard Mobratt; [2023]
    Nyckelord :Evacuation; School children; Fire drill; Fire emergency evacuation; Elementary school; Teachers; Questionnaire Utrymning; Skolbarn; Utrymningsövning; Brandutrymning; Grundskola; Lärare; Enkät; Technology and Engineering;

    Sammanfattning : The aim of this thesis is to study teachers’ perception of children’s ability to evacuate, thus learning about children’s evacuation behavior. Questions of interest are teachers’ perception of children’s ability to evacuate, their behavior, if there are any misconceptions in the teachers’ perception and how fire evacuation drills influence the teachers’ perceptions.

    Nyckelord :Epiroc; electrification; Hopsan; TLPM; linear motor; rock drill; percussion; electromagnetic; simulation; electric motor; mining; electromagnetism;

    Sammanfattning : The world is looking for greener solutions and so is the mining industry. This quest has led to the question whether it is possible to have a completely electric rock drill. This work carries out an initial exploration of completely electrified percussion. LÄS MER

  5. 14. Failure Inference in Drilling Bits: : Leveraging YOLO Detection for Dominant Failure Analysis

    Master-uppsats, Uppsala universitet/Institutionen för informationsteknologi

    Författare :Gnana Spandana Akumalla; [2023]
    Nyckelord :Computer vision; Image processing; Drill bit failure detection; CNN; YOLOv5; FNN; YOLOv8; Dataset; StyleGAN-ADA; Ethics; Sustainability; Artificial Intellegence; Tricone drill bit; Object detection.;

    Sammanfattning : Detecting failures in tricone drill bits is crucial in the mining industry due to their potential consequences, including operational losses, safety hazards, and delays in drilling operations. Timely identification of failures allows for proactive maintenance and necessary measures to ensure smooth drilling processes and minimize associated risks.

  7. 15. Geologisk karaktärisering av den kambriska Faluddensandstenen i Östersjön och dess lämplighet för koldioxidlagring

    Kandidat-uppsats, Lunds universitet/Geologiska institutionen

    Författare :Kaisa Bengtsson; [2023]
    Nyckelord :Koldioxidlagring; djupt liggande akvifer; Faludden; St. Sutarve-2018; CO2-storage; deep saline aquifers; Earth and Environmental Sciences;

    Sammanfattning : The Geological Survey of Sweden (SGU) has spent several years investigating the Swedish bedrock to find suitable bedrock for geological storage of carbon dioxide. Deep saline aquifers are considered to have the greatest potential, and the Cambrian Faludden Sandstone subcropping in the Baltic Sea east of Gotland, shows great potential as a storage aquifer.
