  1. 16. Träningsmodell för neurointervention tillverkad i 3D-skrivare

    Kandidat-uppsats, Lunds universitet/Avdelningen för Biomedicinsk teknik

    Författare :Frida Holmvik; Evelina Persson; [2022]
    Nyckelord :Technology and Engineering;

    Sammanfattning : In life-threatening conditions in the vessels of the brain, neurointervention can be the treatment that saves lives. With only one incision in the vessel of the groin, a catheter can be navigated to the affected vessel and treatment can be performed using tools inserted through the catheter. LÄS MER

  3. 17. Neural Networks for Material Decomposition in Photon-Counting Spectral CT

    Uppsats för yrkesexamina på avancerad nivå, KTH/Medicinteknik och hälsosystem

    Författare :Hugo Charrier; [2022]
    Nyckelord :PCCT; X-ray; scanner; photon counting; AI; neural networks;

    Sammanfattning : Photon counting computed tomography scanners constitute a major improvement of the field of computed tomography, opening various prospective and enabling the decomposition of computed tomography images into different materials. The material decomposition algorithm, mapping photon counts to material pathlengths, relies on a forward model with Poisson statistics. LÄS MER

  4. 18. Towards sustainable shipping: Recommendations for the telescopic mast design of a sailing cargo vessel

    Master-uppsats, KTH/Lättkonstruktioner

    Författare :Lukas Blau; [2021]
    Nyckelord :Oceanbird; telescopic mast; conceptual design; sailing cargo vessel;

    Sammanfattning : A comparative study is carried out to investigate the most promising route towardsthe lightweight construction of a retractable mast for a sailing cargo vessel.Four design families are developed and compared. The primary criteria forjudgment are the structural mass, strength, and stiffness in relation to a providedbenchmark design. LÄS MER

  5. 19. A Comparative Life Cycle Assessment of Alternative Polymers to Poly(vinyl chloride) for Use in Flooring Applications

    Master-uppsats, Lunds universitet/Centrum för analys och syntes

    Författare :Caroline Almqvist; Pernilla Larsson; [2021]
    Nyckelord :PVC; Flooring; Life Cycle Assessment; LCA; Polymer technology; Earth and Environmental Sciences; Chemistry; Technology and Engineering;

    Sammanfattning : Poly(vinyl chloride) has a long history of use in the flooring industry. Throughout the years, several environmental and health issues have arisen concerning the production, usage and disposal of PVC. LÄS MER

  7. 20. An Ion-Selective Electrode for Detection of Ammonium in Wastewater Treatment Plants

    Master-uppsats, KTH/Kemi

    Författare :Josephine Berg; [2021]
    Nyckelord :jonselektiv elektrod; membran; ammonium; sensor; reningsverk; ion-selective electrode ISE ; membrane; ammonium; sensor; wastewater treatment plant WWTP ;

    Sammanfattning : Att följa ammonium i reningsverk är avgörande för att förbättra reningsprocessen och kontrollera flödet av föroreningar ut till ekosystemet. Jonselektiva elektroder (ion-selective electrodes, ISEs) är en lovande teknik inom området, där polymermembran baserade på nonactin är de mest studerade membranen för ammoniumsensorer. LÄS MER
