  1. 1. Simulating metal ct artefacts for ground truth generation in deep learning.

    Master-uppsats, Lunds universitet/Avdelningen för Biomedicinsk teknik

    Författare :Arthur Barakat; [2023]
    Nyckelord :Technology and Engineering;

    Sammanfattning : CT scanning stands as one of the most employed imaging techniques used in clinical field. In the presence of metal implants in the field of view (FOV), distortions and noise appear on the 3D image leading to inaccurate bone segmentation, often required for surgery planning or implant design.

  3. 2. Comparison of Modified Double Tray Method and 3D scanning i prosthodontics

    Master-uppsats, Umeå universitet/Institutionen för odontologi

    Författare :Elsa Nermo; Eloïse Rousseau; [2023]
    Nyckelord :3D scanning; modified double tray method.;

    Sammanfattning : The purpose of this in vitro study was to investigate and to compare the precision of two different impression techniques for oral prosthetic construction, namely the analogue modified double tray method, and the digital three-dimensional scanning with Trios 3D shape intraoral scanner. The analog method used was a modified double tray method where the tray had been removed to diminish vertical discrepancies in occlusion. LÄS MER

  4. 3. Influence of supercritical carbon dioxide (scco2) dyeing parameters on color fastness of polyester fabric dyed with disperse dye : A study towards minimizing the energy consumption of polyester (pet) fabric dyeing with azo disperse dye

    Master-uppsats, Högskolan i Borås/Akademin för textil, teknik och ekonomi

    Författare :Tapas Das; [2023]
    Nyckelord :Supercritical fluid dyeing; polyester PET fabric; coranger orange PE3330; color fastness; ideal dyeing conditions; eco-friendly;

    Sammanfattning : Amid growing environmental concern and continuous depletion of natural resources (such as water), the textile industry is constantly searching for sustainable production process. Traditional dyeing processes, notorious for their enormous water consumption, have led society to search alternative dyeing method. LÄS MER

  5. 4. Chemical modification of starch in order to get thermoplastic properties

    Kandidat-uppsats, KTH/Materialvetenskap

    Författare :Emma Hallbert; Elsa Wadman; [2023]
    Nyckelord :thermoplastic starch; dialdehyde starch; schiff-base; imine chemistry; termoplastisk stärkelse; dialdehydstärkelse; schiffbas; iminkemi;

    Sammanfattning : There are numerous advantages of replacing traditional non-biodegradable synthetic plastics with bio-based plastics. Starch is globally available, cheap, renewable, and biodegradable. However, starch has a poor product performance and is relatively difficult to process, as conventional melt processing techniques cannot be used. LÄS MER

  7. 5. Near Field millimeter Wave Antenna Measurements

    Master-uppsats, Lunds universitet/Institutionen för elektro- och informationsteknik

    Författare :Bharath Manjunatha; [2023]
    Nyckelord :Antenna Pattern; Near field to far field; Planar Scanning; Probe Compensation; Active Antenna; Technology and Engineering;

    Sammanfattning : In the real world, understanding an antenna's radiation pattern is crucial for its proper utilization. Typically, antennas are tested in the far-field region, where the radiation lobes are fully developed and phase errors are less than pi/8. LÄS MER
