  1. 1. Misalignment effects on the physics performance of the inner tracker upgrade at the ALICE experiment

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

    Författare :Jesper Karlsson Gumprecht; [2024]
    Nyckelord :ALICE; ITS; ITS2; ITS3; O2; O2Physics; Distortion; Misalignment; Alignment; Realignment; Physics and Astronomy;

    Sammanfattning : This thesis deals with the physics performance of an approved inner tracker upgrade of the ALICE experiment involving a novel and ultra-thin silicon detector with a cylindrical geometry. During the thesis work, a method was developed in simulations to induce distortions to the detector’s geometry, and the resulting loss in physics performance was evaluated. LÄS MER

  3. 2. DETERMINANTS OF HOUSING PRICES IN SWEDEN : Study of Stockholm, Göteborg and Malmö

    Magister-uppsats, Umeå universitet/Nationalekonomi

    Författare :Ojeawe Ajulo; [2024]
    Nyckelord :;

    Sammanfattning : This study examines the dynamic relationship between house prices, disposable income, lending rate to households, housing supply and population in the three Swedish metropolitan areas of Stockholm, Göteborg and Malmö, using a vector error correction model (vecm). The study uses quarterly data for the Swedish economy and applies the vecm methodology in revealing this dynamic relationship from 2000 – 2022. LÄS MER

  4. 3. Simulating metal ct artefacts for ground truth generation in deep learning.

    Master-uppsats, Lunds universitet/Avdelningen för Biomedicinsk teknik

    Författare :Arthur Barakat; [2023]
    Nyckelord :Technology and Engineering;

    Sammanfattning : CT scanning stands as one of the most employed imaging techniques used in clinical field. In the presence of metal implants in the field of view (FOV), distortions and noise appear on the 3D image leading to inaccurate bone segmentation, often required for surgery planning or implant design.

  5. 4. Language Models as Evaluators : A Novel Framework for Automatic Evaluation of News Article Summaries

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

    Författare :Celine Helgesson Hallström; [2023]
    Nyckelord :Natural Language Processing; Large Language Models; Automatic Text Evaluation; Text Summarization; Multilingualism; Naturlig Språkbehandling; Stora Språkmodeller; Automatisk Textutvärdering; Textsammanfattning; Flerspråkighet;

    Sammanfattning : The advancements in abstractive summarization using Large Language Models (LLMs) have brought with it new challenges in evaluating the quality and faithfulness of generated summaries. This thesis explores a human-like automated method for evaluating news article summaries. LÄS MER

  7. 5. Rolling shutter in feature-based Visual-SLAM : Robustness through rectification in a wearable and monocular context

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

    Författare :Caspar Norée Palm; [2023]
    Nyckelord :SLAM; rolling; shutter; rectification; ORB-SLAM3; monocular; camera; compensation; visual; odometry; simultaneous; localization; mapping;

    Sammanfattning : This thesis analyzes the impact of and implements compensation for rolling shutter distortions in the state-of-the-art feature-based visual SLAM system ORB-SLAM3. The compensation method involves rectifying the detected features, and the evaluation was conducted on the "Rolling-Shutter Visual-Inertial Odometry Dataset" from TUM, which comprises of ten sequences recorded with side-by-side synchronized global and rolling shutter cameras in a single room.
