  1. 1. Application of Fourier Transforms to time-resolved ambient pressure spectroscopy operando studies of CO oxidation over Pt(111)

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

    Författare :Grigore-Leon Ratiu; [2024]
    Nyckelord :Physics and Astronomy;

    Sammanfattning : The study of heterogeneous catalysis has important implications in increasing the efficiency of industrial processes and in reducing the emissions of greenhouse gases from sources such as automobiles. A reaction with high industrial relevance is the oxidation of CO on noble metal catalysts. LÄS MER

    Sammanfattning : Following the rise of Internet of Things (IoT), or just the technological advancements and expectations in a world where the things are or will be connected, new demands are put on Integrated Circuit (IC) for wireless connectivity. The use cases seem endless; smart home, healthcare, entertainment, and science are all areas that can benefit from connectivity of low power electronics. LÄS MER

  4. 3. Phase Unwrapping MRI Flow Measurements

    Uppsats för yrkesexamina på avancerad nivå, Uppsala universitet/Avdelningen Vi3

    Författare :Mio Liljeblad; [2023]
    Nyckelord :phase unwrapping; computer vision; cine MRI; NMR; flow measurements; velocity encoding; venc; energy minimization; magnetic resonance; cardiac MRI; sinotubuar junction; pulmonary artery; ascending descending aorta; laplacian algorithm; iterative graph cuts; IGC; sequential tree-reweighted message passing; TRW-S; velocity to noise ratio; VNR; retrospective wrapping; energy formulation;

    Sammanfattning : Magnetic resonance images (MRI) are acquired by sampling the current of induced electromotiveforce (EMF). EMF is induced due to flux of the net magnetic field from coherent nuclear spins with intrinsic magnetic dipole moments. LÄS MER

  5. 4. X-Ray Tomography on Intestine Samples

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

    Författare :Julia Rogalinski; [2023]
    Nyckelord :Physics and Astronomy;

    Sammanfattning : Enteric neuropathy describes a disease of the bowel caused by anomalies in the enteric nervous system. Patients suffering from this disease have symptoms including nausea, vomiting, diarrhea and pain. As enteric neuropathy is not well understood yet, its diagnosis is a non-trivial task. LÄS MER

  7. 5. Camera Distortion Calibration through Fringe Pattern Phase Analysis

    Master-uppsats, Linköpings universitet/Datorseende

    Författare :Karl Karlsson; [2023]
    Nyckelord :fringe-pattern; distortion; monogenic signal; phase analysis;

    Sammanfattning : The goal of this thesis is to use fringe-pattern phase analysis to calibrate the distortion of a camera lens. The benefit of using this method is that the distortion can be calculated using data from each individual pixel and the methodology does not need any model. LÄS MER
