  1. 1. 3D Object Manipulation in Volumetric Video Production

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

    Författare :Xinyi Wang; [2023]
    Nyckelord :Volumetric Video Production; Holographic Communication; Digital Human with 3D Object Manipulation; Human-Computer Interaction; Volumetrisk videoproduktion; holografisk kommunikation; digital människa med 3D-objektmanipulation; människadatorinteraktion;

    Sammanfattning : Remote communication methods have been changing these years and becoming even more important due to the global pandemic. Holographic communication, often represented by volumetric video, is one of the emerging communication methods. Unfortunately, there are few researches on combining 3D objects with volumetric videos.

  3. 2. A VVER1000 primary side model in Apros

    Master-uppsats, KTH/Fysik

    Författare :Karl-Edvin Strand; [2023]
    Nyckelord :Apros; VVER1000; PWR; Modelling; HPIS; Boron acid; Apros; VVER1000; PWR; Modellering; HPIS; Borsyra;

    Sammanfattning : Nuclear power plants generate electricity by means of splitting atoms. The basic safety requirements and objectives are to protect the people, society, and the environment from radiological accidents, limit harmful effects of ionizing radiation during operation and take all reasonable practical steps to prevent radiological accidents.

  4. 3. Uncertainty Estimation in Volumetric Image Segmentation

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

    Författare :Donggyun Park; [2023]
    Nyckelord :Uncertainty Estimation; Uncertainty Quantification UQ ; Volumetric Image Segmentation; 3D U-Net; test-time data augmentation; Deep ensemble;

    Sammanfattning : The performance of deep neural networks and estimations of their robustness has been rapidly developed. In contrast, despite the broad usage of deep convolutional neural networks (CNNs)[1] for medical image segmentation, research on their uncertainty estimations is being far less conducted. LÄS MER

  5. 4. Development of Nickel-Titanium Shape Memory Alloys using Electron Beam Melting

    Master-uppsats, KTH/Materialvetenskap

    Författare :Georgios Manolios; [2022]
    Nyckelord :;

    Sammanfattning : In this project, the effect of electron beam melting on the behavior of NiTi shape memory alloyshas been studied, with focus on the effects of recycling powder within the process and theprocess parameters used and how “smoking” is affected. Flowability, powder characteristicsand chemical composition have been evaluated using imaging analysis techniques, Hallflowmeter measurements, FT4 powder rheometry and energy dispersive X-ray spectroscopyboth in virgin powder and in recycled powders.

  7. 5. Selection Intent Prediction in Online Virtual Environments : A Comparison Study

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

    Författare :Charles-Eole Marichal; [2022]
    Nyckelord :HCI; XR; Selection; Prediction; Online virtual environments; MDI; XR; Urval; Förutsägelse; Virtuella online-miljöer;

    Sammanfattning : In this work, we address the problem of the selection of 3D objects based on the user’s intent to interact with them in online virtual environments, both on desktop and VR devices. In addition to the traditional ray-casting technique, we select four promising techniques from the literature using time-dependent volumetric scoring (IntenSelect), trajectory prediction (KEP), Kalman filters enhancement (KalmanKEP) and machine learning with decision trees (MTP).
