    • Chest compressions: The good, the bad and the ugly 

      Eftestøl, Trygve (Journal article, 2012)
      Where exactly is the chest compression, where does it begin, when does it end, how deep does it go and at what rate are they performed? In short – how good or bad is the chest compression? These are some of the questions ...
    • Activity-Oriented Petri Net for scheduling of resources 

      Davidrajuh, Reggie (Conference object, 2012-10)
      This work presents a new methodology for modeling discrete systems in which activities compete for resources. The new methodology known as Activity-Oriented Petri Net (AOPN) allows modelers to concentrate on modeling ...
    • Probability mapping of scarred myocardium using texture and intensity features in CMR images 

      Kotu, Lasya Priya; Engan, Kjersti; Skretting, Karl; Måløy, Frode; Ørn, Stein; Woie, Leik; Eftestøl, Trygve (Journal article, 2013)
    • Distributed workflow based approach for eliminating redundancy in virtual enterprising 

      Davidrajuh, Reggie (Journal article; Peer reviewed, 2013-01)
      The existence of redundancy is a serious problem in virtual enterprise in which a number of collaborating enterprises join together to manufacture and sell a class of product for a time-limited period. This paper proposes ...
    • Revisiting Petri Net Modeling of the Cigarette Smokers' Problem: A GPenSIM Approach 

      Davidrajuh, Reggie (Conference object, 2013-11)
      Petri Nets is a family of modeling formalisms, with different interpretations and abstraction levels; the Petri nets family of modeling formalisms includes ordinary Petri Net, generalized Petri Net, and also all other ...
    • Defining angular and radial positions and parameters for myocardial pixels in cardiac MR images 

      Engan, Kjersti; Woie, Leik; Eftestøl, Trygve (Journal article; Peer reviewed, 2014)
      In this work we aimed to automatically produce a measure for the angular and radial position of all pixels within the myocardium in CMR images, left ventricle, short axis view. A reference axis is chosen in an anatomically ...
    • Rhythm analysis during cardiopulmonary resuscitation: past, present, and future 

      Ruiz de Gauna, Sofia; Irusta, Unai; Ruiz, Jesus; Ayala, Unai; Aramendi, Elisabete; Eftestøl, Trygve (Journal article; Peer reviewed, 2014-01)
      Survival from out-of-hospital cardiac arrest depends largely on two factors: early cardiopulmonary resuscitation (CPR) and early defibrillation. CPRmust be interrupted for a reliable automated rhythmanalysis because chest ...
    • Classifying dementia using local binary patterns from different regions in magnetic resonance images 

      Oppedal, Ketil; Eftestøl, Trygve; Engan, Kjersti; Beyer, Mona K.; Aarsland, Dag (Journal article; Peer reviewed, 2015)
      Dementia is an evolving challenge in society, and no disease-modifying treatment exists. Diagnosis can be demanding and MR imaging may aid as a noninvasive method to increase prediction accuracy. We explored the use of 2D ...
