  1. 26. Thermo-mechanical vibration technique for degating of high-pressure die casting component – A numerical study

    Magister-uppsats, Jönköping University/JTH, Material och tillverkning

    Författare :Ramkumar Kandasamy; [2023]
    Nyckelord :High-pressure die casting; Thermo-mechanical vibration; Finite Element Method; ANSYS WB.;

    Sammanfattning : The purpose of the thesis work given is to gain a better understanding of the degating process in high-pressure die casting components, as well as the effectiveness of the thermo-mechanical vibration technique for detaching cast components from the gating system. In addition, to evaluate and establish the most appropriate degating procedure in order to reduce labor, material costs, and processing time. LÄS MER

  3. 27. Improving the experimental setup for ultrasound-optical tomography imaging

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

    Författare :Ibtisam Dahir Ahmed; [2023]
    Nyckelord :Ultrasound-optical tomography UOT ; thulium-doped lithium niobate;

    Sammanfattning : According to Bröstcancer förbundet, mammography is not efficient at detecting tumors in dense breast tissue or diagnosing breast cancer at its early stages. Ultrasound-optical tomography (UOT) is an imaging technique in development and has the potential for deep-tissue imaging. LÄS MER

  5. 29. Anomaly Vibration Classification for Condition Monitoring in Passenger Cars

    Master-uppsats, Uppsala universitet/Institutionen för informationsteknologi

    Författare :Rui Zhou; [2023]
    Nyckelord :;

    Sammanfattning : This research aims to investigate accurate classification of anomalous vibrations produced during vehicle operation. The main research questions are which data can be used as classification criteria, which models can better achieve classification effects, and how to address classification issues under different variables in a car.

  7. 30. Comparative Analysis of Spatiotemporal Playback Manipulation : Evaluating Desktop Environments versus Immersive Head-Mounted Virtual Reality Environments

    Master-uppsats, KTH/Skolan för elektroteknik och datavetenskap (EECS)

    Författare :Andreas Wrife; [2023]
    Nyckelord :virtual reality; surgical simulations; external ventricular drainage; motion capture; interaction controls; virtuell verklighet; kirurgiska simuleringar; extern ventrikeldränage; motion capture; interaktionskontroller;

    Sammanfattning : Virtual Reality (VR) is a creative tool that enables immersive learning, planning and training of surgical operations. Extensive research has been conducted in multiple surgical specialities where VR has been utilized, such as spinal neurosurgery. However, cranial neurosurgery remains relatively unexplored in this regard. LÄS MER
