  1. 1. Leveling the Playing Field: Can Private Investors Benefit From Mimicking Insider Trades? A quantitative study of insider trading

    Master-uppsats, Göteborgs universitet/Graduate School

    Författare :Marcus Mattsson; Marcus Lyckhage; [2023-07-04]
    Nyckelord :Insider Trading; Abnormal Return; Information Asymmetry; Outside Investors; Investment Strategy; Insider Positions;

    Sammanfattning : Historically, investors have been searching for strategies to maximize performance in the stock market. It has been shown that corporate insiders can earn abnormal returns by trading in their own companies as they possess superior information and, to a certain degree, market timing ability. LÄS MER

  3. 2. Information Extraction for Test Identification in Repair Reports in the Automotive Domain

    Master-uppsats, Uppsala universitet/Institutionen för lingvistik och filologi

    Författare :Huang Jie; [2023]
    Nyckelord :text classification; information retrieval; contrastive learning; prompt-based fine-tuning; large language models;

    Sammanfattning : The knowledge of tests conducted on a problematic vehicle is essential for enhancing the efficiency of mechanics. Therefore, identifying the tests performed in each repair case is of utmost importance. This thesis explores techniques for extracting data from unstructured repair reports to identify component tests. LÄS MER

  4. 3. Quality enhancement of time-resolved computed tomography scans with cycleGAN

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

    Författare :Johannes Stubbe; [2023]
    Nyckelord :carbon fibers; carbon fibres; microfibers; tomography; deep learning; cycleGAN; time-resolved tomography; Physics and Astronomy;

    Sammanfattning : Time-resolved x-ray tomography enables us to dynamically and non-destructively study the interior of a specimen. The obtainable temporal resolution is limited by the x-ray flux and the desired spatial resolution. LÄS MER

  5. 4. Probing Charm Production with Three-Particle Correlations in pp Collisions

    Kandidat-uppsats, Lunds universitet/Fysiska institutionen; Lunds universitet/Partikel- och kärnfysik

    Författare :Kim Haupt; [2023]
    Nyckelord :pp collisions; charm production; three-particle correlation; Pythia; Physics and Astronomy;

    Sammanfattning : This thesis aims to investigate possible correlations between charm production and baryon production in proton-proton collisions through three-particle correlations. The question attempted to be answered is where, for a given charmed baryon, the balancing anti-charm particle and balancing anti-baryon are located. LÄS MER

  7. 5. Control Aid Implementation -Modelling and simulation of triple extruder-

    Master-uppsats, Lunds universitet/Kemiteknik (CI)

    Författare :Karl Langsér; [2023]
    Nyckelord :Machine Learning; Extruder; Modelling; Simulation; Extreme learning machine; Chemical engineering; Technology and Engineering;

    Sammanfattning : In the production of their High Voltage Direct Current Cables (HVDC) and High Voltage Alternating Current Cables (HVAC), NKT uses triple extruders to create layers of insulation and semi-conduction. A model to predict the effect of extruder inputs on the cable’s insulation and semi-conducting layers has been created and trained to predict the extruder in discrete time. LÄS MER
