    • Digital Twins For Topology Density Map Analysis 

      Hu, Zhicheng; Hasan, Agus Ismail; Da Silva Torres, Ricardo (Chapter, 2023)
      Properly analyzing spatiotemporal patterns is of paramount importance, especially in urban planning. In this paper, we introduce two digital twins to support the analysis of spatiotemporal data associated with urban ...

    • Encoding and Visualizing Temporal Changes of Topology Density Maps 

      Hu, Zhicheng (Master thesis, 2022)
      Spatiotemporal urban data analysis is one of the most relevant and challenging topics in the computer graphics and information visualization research areas. This master project introduces a novel solution, named Temporal ...

    • Identification of optimal accelerometer placement on trains for railway switch wear monitoring via multibody simulation 

      Hu, Zhicheng; Lau, Albert; Dai, Jian; Frøseth, Gunnstein Thomas (Journal article; Peer reviewed, 2024)
      Accelerometers play a crucial role in the railway industry, especially in track monitoring. Traditionally, they are placed on the railway tracks or often on bridges to monitor the health and condition of the infrastructure. ...

    • Kan Random Forest finne sporveksler i Roger-1000-data? 

      Runningen, Kirsten (Master thesis, 2024)
      I denne oppgaven ble det undersøkt om Random Forest modellen kunne finne sporveksler, og unngå falske sporveksler, ved å analyser Roger-1000-data. Det ble utført en fordypnignsoppgave før denne masteren, og ved nærmere ...

    • On Demand Waste Collection for Smart Cities: A Case Study 

      Alaliyat, Saleh Abdel-Afou; Mishra, Deepti; Schaarschmidt, Ute Alexandra; Hu, Zhicheng; Haghshenas, Amirashkan; Giarre, Laura (Chapter, 2022)
      The neat and clean surrounding is the main driving force for any city to be called a smart city. In order to address current societal and business challenges, the objective is to provide a solution to enable collection-on-demand ...
