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

    University essay from Lunds universitet/Fysiska institutionen; Lunds universitet/Synkrotronljusfysik

    Author : Grigore-Leon Ratiu; [2024]
    Keywords : Physics and Astronomy;

    Abstract : 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. READ MORE

  3. 2. Fano Resonances in Time-Dependent Wells

    University essay from Uppsala universitet/Materialteori

    Author : Anton Gregefalk; [2023]
    Keywords : Fano resonance; Floquet scattering; Pumped shot-noise; Linear band tilt; Quadratic band touching; Time periodic Hamiltonian;

    Abstract : Floquet’s theorem, a temporal analogue of Bloch’s theorem, is used for studying a time-dependent potential. With applications in cold atoms on optical lattices, quantum dots and more, there is a growing interest in Floquet engineering exotic materials and phases. READ MORE

  4. 3. Characterisation of the LYCCA Double-Sided Silicon Strip Detectors

    University essay from Lunds universitet/Fysiska institutionen; Lunds universitet/Partikel- och kärnfysik

    Author : Marwan Mohamed; [2023]
    Keywords : DSSD LYCCA HISPEC FAIR Characterisation; Physics and Astronomy;

    Abstract : The goal of this thesis work is to describe the methods used and perform comprehensive testing of the Double-Sided Silicon-Strip Detectors (DSSD) prior to their implementation in the Lund-York-Cologne CAlorimeter (LYCCA) detector. In the framework of this project, the DSSD characterisation was carried out to ensure specification compliance prior to their "in-kind contribution" delivery to the HISPEC experiment at the NUSTAR collaboration.

  5. 4. Anomaly Detection in District Heating using a Clustering based approach

    University essay from

    Author : Minh-Tung Nguyen; Metjan Baduni; [2021]
    Keywords : Anomaly Detection; Data Mining; Unsupervised Machine Learning; Clustering; DBSCAN; Time Series;

    Abstract : The global demand for energy has increased in recent years. In Northern Europe and North America, centralized production and distribution of heat energy is commonly regarded as District Heating (DH). Efficient delivery of heat in the DH system is crucial not only for the building dwellers but even for companies that supply such energy. READ MORE

  6. 5. Improving image quality of a streak camera using periodic shadowing

    University essay from Lunds universitet/Fysiska institutionen; Lunds universitet/Förbränningsfysik

    Author : David-Gabriel Lange; [2021]
    Keywords : combustion physics; laser; lock-in amplification; laser induced fluorescence; periodic shadowing; Rhodamine B; streak camera; Mode-locking; microfluidics; fluorescence lifetime imaging; Physics and Astronomy;

    Abstract : Stray light suppression using a method inspired by lock-in amplification, called periodic shadowing, is examined and demonstrated for a measurement involving a streak camera. The experiment consists of resolving the fluorescent decay of the dye Rhodamine B (RhB) and examining both the rise and the decay of the fluorescence. READ MORE
