  1. 1. Assessment of aggregate structure in porous asphalt using X-ray computed tomography

    Master-uppsats, KTH/Väg- och banteknik

    Författare :Mari Haagenrud Matsson; Malex Love Valdemar Åkerblom; [2023]
    Nyckelord :Tomography; non-destructive testing; destructive testing; air voids content; aggregate size distribution; porous asphalt;

    Sammanfattning : X-ray computed tomography is a technique that has been successfully utilized to characterize internal microstructure of asphalt mixtures. The city of Linköping (Sweden) developed an action plan to reduce noise; accordingly KTH and VTI developed a method to determine air void content in porous asphalt using x-ray computed tomography and an image processing software called ImageJ.

  3. 2. Battery field data-oriented investigation of cell capacity spread and its impacts

    Master-uppsats,

    Författare :Muhammad Bilal; [2022]
    Nyckelord :Cell Capacity; Electric Vehicles; Algorithm; Current Profile; Voltage;

    Sammanfattning : In this research thesis, a new data-centric approach is used to determine the individual cell capacities in Li-ion batteries used in electric vehicles (EVs). This approach could also be extended to batteries for static energy storage applications. LÄS MER

  4. 3. Supply chain effects of utilizing non destructive quality inspection in food production

    Uppsats för yrkesexamina på avancerad nivå, Luleå tekniska universitet/Institutionen för ekonomi, teknik, konst och samhälle

    Författare :Fredrik Klein; [2022]
    Nyckelord :waste; inventory; production; food; quality;

    Sammanfattning : Reducing waste and increasing efficiency in food supply chains is important for a sustainable food production. Modified Atmosphered Packaging (MAP) is a method of increasing food durability that requires gas quality and potential gas leakage inspection. LÄS MER

  5. 4. Synchrotron X-ray Tomography Study of Bone-implant Integration

    Master-uppsats, Lunds universitet/Avdelningen för Biomedicinsk teknik

    Författare :Ornella Lohéac; [2021]
    Nyckelord :Bone-implant; Digital volume correlation; Micro-computed tomography; PEEK; Synchrotron; Technology and Engineering;

    Sammanfattning : Implant loosening is a recurring problem in the field of orthopedics, typically resulting in a physical and financial burden for the patient. Proper integration of orthopedic implants within host bones is a fundamental requirement for the successful function and limited risk of failure of implants which, in-vivo, must support various loading conditions.

  7. 5. Detection of voids in welded joints using ultrasonic inspection : Quality control of welded joints in copper canisters for purpose of permanent storage of used nuclear waste

    Kandidat-uppsats, Uppsala universitet/Institutionen för elektroteknik

    Författare :Bakhtiar Afzalan; [2021]
    Nyckelord :Ultrasonic inspection; Nuclear waste; Nuclear waste storage; welded joints;

    Sammanfattning : This thesis was done i cooperation with SKB Clab in Oskarshamn and studies use of sonic waves for detecting voids and irregularities in the weld joints of copper capsules used for long term storage of radioactive waste. Since these could pose material failure and thereby risk radioactive contamination of ground water it is very important to find means of quality control before storage. LÄS MER
