  1. 21. Limited angle reconstruction for 2D CT based on machine learning

    Kandidat-uppsats, KTH/Skolan för teknikvetenskap (SCI)

    Författare :Eric Oldgren; Knut Salomonsson; [2023]
    Nyckelord :CT; computed tomography; limited angle; machine learning; limited data; ill posed problem; inverse problem;

    Sammanfattning : The aim of this report is to study how machine learning can be used to reconstruct 2 dimensional computed tomography images from limited angle data. This could be used in a variety of applications where either the space or timeavailable for the CT scan limits the acquired data.In this study, three different types of models are considered.

  2. 22. Assessing the Efficiency of COLMAP, DROID-SLAM, and NeRF-SLAM in 3D Road Scene Reconstruction

    Master-uppsats, Lunds universitet/Matematik LTH

    Författare :Marcus Ascard; Farjam Movahedi; [2023]
    Nyckelord :3D reconstruction; Visual SLAM; Pose evaluation; Point cloud evaluation; Road scenes; Technology and Engineering;

    Sammanfattning : 3D reconstruction is a field in computer vision which has evolved rapidly as a result of the recent advancements in deep learning. As 3D reconstruction pipelines now can run in real-time, this has opened up new possibilities for teams developing Advanced Driver Assistance Systems (ADAS), which rely on the camera system of the vehicle to enhance the safety and driving experience.

  3. 23. International Contribution to Rebuilding Cities : A Content Analysis of the United Nations Initial Post-Conflict Reconstruction Framework for the City of Mosul

    Kandidat-uppsats, Uppsala universitet/Kulturgeografiska institutionen

    Författare :Hedvig Hultén; [2023]
    Nyckelord :Reconstruction; the United Nations; Mosul; post-conflict; sustainable peace;

    Sammanfattning : This study aims to analyze the design of the United Nations post-conflict reconstruction plans and their role as an international actor. To answer this, a qualitative content analysis was conducted on the written content of the “Initial Planning Framework for the Reconstruction of Mosul”. LÄS MER

  4. 24. Digitala tvillingars användning vid beslutsfattning i bygg- och fastighetsbranchen

    Kandidat-uppsats, Uppsala universitet/Företagsekonomiska institutionen

    Författare :Josefine Mattsson; [2023]
    Nyckelord :Digital twins; construction and real estate industry; decision-making; situation awareness; digitalization; Digitala tvillingar; bygg- och fastighetsbranschen; beslutsfattning; situationsmedvetenhet; digitalisering;

    Sammanfattning : Bygg- och fastighetsbranschen präglas av långsam digitaliserings takt där bristande dokumentation förekommer och i vissa fall försvårar beslutsfattningsmoment. Digitala tvillingar är kända för att effektivisera fastighetsförvaltning och bidra till bättre beslutsfattning. LÄS MER

  5. 25. Methodology for Designing Bespoke Air Handling Units

    Master-uppsats, KTH/Energiteknik

    Författare :Alexandra Malysheva; [2023]
    Nyckelord :bespoke air handling unit; evaporative cooling system; two-stage crossflow heat exchanger; 3D-modeling; platsbyggt luftbehandlingsaggregat; evaporativt kylsystem; tvåstegs motströmsvärmeväxlare; 3D-modeling;

    Sammanfattning : This master's thesis explores the role of bespoke air handling units in enhancing energy efficiency in existing buildings. The context for the study is set against the backdrop of global initiatives, including the United Nations' Sustainable Development Goals, specifically Goal 7, which emphasizes the need to improve energy efficiency to combat climate change.
