  1. 6. Synchrotron X-ray Tomography Study of Bone-implant Integration

    University essay from Lunds universitet/Avdelningen för Biomedicinsk teknik

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

    Abstract : 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.

  3. 7. The Effect of High Wheel Impact Load on the Rail Reliability - a Case Study at Bodsjön

    University essay from KTH/Spårfordon

    Author : Ngoc Thúy Vy Dang; [2021]
    Keywords : rail defects; rail reliability; Ultrasonic Test; wheel damage; Wheel Impact Load Detector; statistics; järnvägsdefekter; järnvägssäkerhet; ultraljudstest; hjulskador; hjullastningsdetektor; statistik;

    Abstract : This study focuses on the reliability of railway track in the relation with high loads resulted from wheel damages, where higher (dynamic) vertical wheel loads are expected from trains with damaged wheels. The Swedish Transport Administration (Trafikverket) has monitored and recorded data of rail defects and breaks. READ MORE

  4. 8. Estimation of the characteristic in-situ compressive strength class of concrete structures - A case study of the Skuru bridge

    University essay from KTH/Bro- och stålbyggnad

    Keywords : existing; structures; characteristic; in-situ; compressive; non-destructive; semi-destructive; destructive; cores; EN13791; GCSC; TDOK; UPV; Rebound; Pull-out; Windsor; correlation; calibrate; indirect; direct; estimate; befintlig; konstruktion; karakteristisk; tryckhållfasthet; icke-destruktiv; halv-destruktiv; destruktiv; kärnor; EN13791; GCSC; TDOK; UPV; Rebound; Utdragskraft; Windsor; korrelation; kalibrera; indirekt; direkt; bedöma;

    Abstract : It is inevitable that Structures become older and their intended use changes or the structuralcodes regulations change. In some regions the damage from seismic activities is a possibility.It becomes, therefore crucial to assess the structural capacity of such structures. READ MORE

  5. 9. Direct Sampling of the Pulsed Eddy Current Response From Non-Ferromagnetic Metals

    University essay from Umeå universitet/Institutionen för fysik

    Author : Sara Holmér; [2021]
    Keywords : ;

    Abstract : The non-destructive testing method Pulsed Eddy Current, or PEC, can be used to measure the thickness and resistivity of conducting and non-ferromagnetic materials. In this project I investigated if a gauge at ABB, which uses PEC technology to measure the thickness of aluminium strips in rolling mills, can extract more information about the strip by sampling the direct signal with a higher resolution than before.

  6. 10. Investigation of Air Void Structure in Double Layer Porous asphalt based on X-ray Computed Tomography

    University essay from KTH/Byggvetenskap

    Author : Shuchen Gong; [2020]
    Keywords : Tomography; non-destructive testing; destructive testing; air voids content; porous asphalt drilled cores;

    Abstract : The X-ray computed tomography is a technology to investigate air void structure of drilled asphalt cores, which provides a non-destructive alternative to traditional laboratory methods, usually destructive testing.In this work, six in-situ specimens from a double layer porous asphalt pavement in Linköping, Sweden, were taken and analysed using both qualitative and quantitative methods of tomography.
