  1. 1. Clustering on groups for human tracking with 3D LiDAR

    Master-uppsats, Umeå universitet/Institutionen för datavetenskap

    Författare :Simon Utterström; [2023]
    Nyckelord :Computer Vision; Computer Science; AI; Machine Learning; clustering; Kernel Density Clustering; tracking; LiDAR; 3D LiDAR; tracking; human; pedestrian; real time; Datavetenskap; Dataseende; clustering; SLR; CVC; KDEG; KDE; Kernel Density Clustering; HDBSCAN; DBSCAN; LiDAR; point cloud; tracking; human; pedestrian;

    Sammanfattning : 3D LiDAR people detection and tracking applications rely on extracting individual people from the point cloud for reliable tracking. A recurring problem for these applications is under-segmentation caused by people standing close or interacting with each other, which in turn causes the system to lose tracking. LÄS MER

  3. 2. Evaluation of whole-body bone scans performed using a gamma camera with Cadmium Zinc Telluride detector

    Master-uppsats,

    Författare :Victor Asp; [2022-01-13]
    Nyckelord :Medical physics; whole-body bone scans; gamma camera; Cadmium Zinc Telluride detector;

    Sammanfattning : The bone scan is a common nuclear medicine imaging procedure that is mainly used for evaluating several oncological patient groups. A radioactive tracer, 99mTc -labelled diphosphonate, is injected intravenously and accumulates in the skeleton. The distribution of the tracer in the body is measured with a gamma camera 3 hours post-injection. LÄS MER

  4. 3. Geological characterization of rock samples by LIBS and ME-XRT analytical techniques

    Master-uppsats, Luleå tekniska universitet/Geovetenskap och miljöteknik

    Författare :Nsioh Elvis Nkioh; [2022]
    Nyckelord :geological characterization; analytical techniques; LIBS; ME-XRT; SEM; element maps; SEM-EDS; secondary electrons; rock samples; automated ore microscopy; SEM-Zeiss Merlin; element weight percentages; element oxide percentages; scanning techniques; analytical methods; laser induced breakdown spectrometry; multi energy x-ray transmission; scanning electron microscope; carbon coating; mineralogical classification; element composition; rock chemistry; rock chemical composition;

    Sammanfattning : One of the major challenges in earth sciences and mineral exploration has been to determine with high accuracy and at a fast rate the elemental composition as well as the general chemistry of a rock sample. Many analytical techniques e.g. LÄS MER

  5. 4. Automating the Part Identification Method of Automotive Assembly Lines Through RFID Technology

    Master-uppsats, KTH/Industriella produktionssystem

    Författare :Felix Buchner; [2022]
    Nyckelord :RFID; General Assembly; Part identification; Traceability; Automotive industry; Genealogy; Barcode scan; Vehicle scan; RFID; allmän montering; Identifiering av delar; Spårbarhet; Fordonsindustrin; Genealogi; Skanning av streckkoder; Skanning av fordon;

    Sammanfattning : Barcode scanning has been used for many decades in the assembly process to identify individual parts. Besides the fact that scanning is a non-value-adding operation, it also is prone to error. It cannot beensured with certainty that the scanned part will be the part installed. LÄS MER

  7. 5. Mitigating SSCI in a hybrid wind and PV farm utilizing PV-STATCOM : A Swedish case study

    Master-uppsats, Högskolan Dalarna/Institutionen för information och teknik

    Författare :Isabelle Löfgren; [2022]
    Nyckelord :impedance analysis; PV-STATCOM; SSCI; SSO; SSR; sub-synchronous control interaction;

    Sammanfattning : The share of electricity generation in the power system being based on power electronics is increasing, which will impact the system in different ways, such as an increased risk for undesired interactions. An example is doubly fed induction generator (DFIG) based windfarms which have been shown to present negative resistance in (parts of) the sub-synchronous range (i. LÄS MER
