• An Optimization Framework for Tracking Droplets in Fire Water Spray Images 

      Lundberg, Joachim; Lysaker, Ola Marius (Conference object; Peer reviewed, 2015-11-25)
      The properties of the flow from fire water nozzles, like droplet size and velocity distribution within the spray, are known to influence the fire suppression efficiency. To analyze the flow properties, the water spray is ...
    • Bidomain Simulations of Subendocardial Ischemia: The Forward and Inverse Problems 

      Lysaker, Ola Marius; Nielsen, Bjørn Fredrik; Wall, Samuel (Journal article; Peer reviewed, 2014-09)
      We provide an analysis of the bidomain theory in relation to anterior subendocardial ischemia. Using the static bidomain model, this analysis explains why simulations often do not produce ST depression when the ischemia ...
    • Observability of Ischemia and the Need for Patient Specific Geometrical Models in Inverse ECG. 

      Lines, Glenn Terje; Lysaker, Ola Marius; Nielsen, Bjørn Fredrik (Conference object; Peer reviewed, 2013-09)
      We have performed ECG simulations on four realistic geometries in order to quantify the effect of ischemic location in the left ventricle in terms of ST shifts in the body surface potential (BSP). Using 64 electrodes we ...
    • Open Active Contour Model For Front Tracking Of Detonation Waves 

      Maharjan, Samee; Lysaker, Ola Marius; Gaathaug, André Vagner (Journal article; Peer reviewed, 2017)
      This paper presents an image processing framework for tracking the front of the detonation wave from a sequence of images. The images are captured by high speed camera during a laboratory gas explosion experiment. By ...
