  1. 36. Deep Learning for estimation of fingertip location in 3-dimensional point clouds : An investigation of deep learning models for estimating fingertips in a 3D point cloud and its predictive uncertainty

    University essay from Linköpings universitet/Statistik och maskininlärning

    Author : Phillip Hölscher; [2021]
    Keywords : Deep Learning; Point Cloud; Hand Pose Estimation; Fingertip Localization; Model Uncertainty;

    Abstract : Sensor technology is rapidly developing and, consequently, the generation of point cloud data is constantly increasing. Since the recent release of PointNet, it is possible to process this unordered 3-dimensional data directly in a neural network. READ MORE

  3. 37. Investigation of a Collapsed Cone Superposition Algorithm for dosimetry in brachytherapy

    University essay from Stockholms universitet/Fysikum

    Author : Freja Alpsten; [2021]
    Keywords : Brachytherapy; Collapsed Cone; Model-Based Dose Calculation Algorithms; Radiotherapy;

    Abstract : Background & Purpose: The current standard dosimetry in brachytherapy treatment planning, the TG-43 formalism, ignore the presence of non-water media and finite patient dimensions. This can cause clinically relevant errors in dose estimates. READ MORE

  4. 38. Positioning in Non-Terrestrial Networks

    University essay from Lunds universitet/Institutionen för elektro- och informationsteknik

    Author : Soha Emara; [2021]
    Keywords : positioning; 5G; satellite; NTN; Technology and Engineering;

    Abstract : In 5G communications, Non-terrestrial Network (NTN) is envisioned to complement Terrestrial Network (TN) to increase network availability, scalability and continuity. Positioning of User Equipment (UE) is critical for the operation of NTN. Currently, NTN uses Global Navigation Satellite System (GNSS) for positioning. READ MORE

  5. 39. Tracking of Sinking Underwater Node using Inertial Navigation

    University essay from Mälardalens högskola/Akademin för innovation, design och teknik

    Author : Kristoffer Lindve; [2021]
    Keywords : ;

    Abstract : Tracking objects underwater is prone to error since no equivalent system to GPS exists for underwater applications. Accurate positioning is vital for conducting surveillance. However, it is hard for a system to keep an accurate prediction while moving without a GPS source. READ MORE

  6. 40. A Machine Learning Approach for Comprehending Cosmic Expansion

    University essay from KTH/Fysik

    Author : Ludvig Doeser; [2021]
    Keywords : Cosmology; Cosmic expansion; Galaxy Images; Machine learning; Kosmologi; kosmisk expansion; galaxbilder; maskininlärning;

    Abstract : This thesis aims at using novel machine learning techniques to test the dynamics of the Universe via the cosmological redshift-distance test. Currently, one of the most outstanding questions in cosmology is the physical cause of the accelerating cosmic expansion observed with supernovae. READ MORE
