    • Viscosity Models for Drilling Fluids: Herschel-Bulkley Parameters and Their Use 

      Saasen, Arild; Ytrehus, Jan David (Peer reviewed; Journal article, 2020)
      An evaluation is presented of the practical usage of the Herschel-Bulkley viscosity model for drilling fluids. If data from automatic viscosity measurements exist, the parameters should be selected from relevant shear rate ...
    • Vision transformer and explainable transfer learning models for auto detection of kidney cyst, stone and tumor from CT-radiography

      Renal failure, a public health concern, and the scarcity of nephrologists around the globe have necessitated the development of an AI-based system to auto-diagnose kidney diseases. This research deals with the three major ...
    • Visualisation of Train Punctuality – Illustrations and Cases 

      Landmark, Andreas D.; Seim, Andreas Røsland; Olsson, Nils (Journal article; Peer reviewed, 2017)
      The purpose of this paper is to show relevant dimensions for presenting railway punctuality data. We discuss alternatives for visualisation and analysis, and show principles and practical examples. The study has benefitted ...
    • Visualization of user-defined elements in Abaqus 

      Osen, Vidar (SINTEF Rapport;1504-9795, Research report, 2018)
