  1. 21. In-vivo assessment of unwanted tissue heating during near infrared laser light emission

    Master-uppsats, Lunds universitet/Atomfysik; Lunds universitet/Fysiska institutionen

    Författare :Martin Molin; [2020]
    Nyckelord :tissue heating; laser heating; NIR window; biophotonics; spectroscopy; Medicine and Health Sciences;

    Sammanfattning : In this work, potential adverse tissue heating in conjunction with near infrared (NIR) laser spectroscopy was studied. The tissue heating from laser light within the NIR optical window is currently a relatively unexplored field. LÄS MER

  3. 22. LIBS Multivariate Analysis with Machine Learning

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

    Författare :Olivier Nicolini; [2020]
    Nyckelord :;

    Sammanfattning : Laser-Induced Breakdown Spectroscopy (LIBS) is a spectroscopic technique used for chemical analysis of materials. By analyzing the spectrum obtained with this technique it is possible to understand the chemical composition of a sample. LÄS MER

  5. 24. Modelling of Laser Welding of Aluminium using COMSOL Multiphysics

    Master-uppsats, KTH/Materialvetenskap

    Författare :Jie Chen; [2020]
    Nyckelord :laser welding process; aluminium alloy; thermal-mechanical; COMSOL Multiphysics; hot cracking; thermal model; CFD model; mechanical model; Marangoni effect; lasersvetsningsprocess; aluminiumlegeringar; termisk-mekanisk; COMSOL-flerfysik; hetsprickning; termisk modell; CFD-modell; mekanisk modell; Marangoni-effekt;

    Sammanfattning : This thesis presents a modelling approach of laser welding process of aluminium alloy from the thermo-mechanical point of view to evaluate the occurrence of hot cracking based on simulation results and relevant criteria. The model was created stepwise in COMSOL Multiphysics, starting with the thermal model where heat conduction of solid and liquid phase was computed. LÄS MER

  7. 25. In-vivo study on the stability of the use of gas absorption spectroscopy as a technology for assessing sinus cavity size and oxygen gas concentration

    Master-uppsats, Lunds universitet/Avdelningen för Biomedicinsk teknik
