    • Meal estimation from Continuous Glucose Monitor data using Kalman filtering and hypothesis testing 

      Staal, Odd Martin; Sælid, Steinar; Fougner, Anders Lyngvi; Stavdahl, Øyvind (Journal article; Peer reviewed, 2019)
      A method for estimating meal inputs from Continuous Glucose Monitoring (CGM) data is presented. The method is based on Kalman filtering and hypothesis testing, and provides estimates of the time the meal was initiated and ...
    • Modelling and Implementation of Glycemic Response Calculator 

      Stige, Peter Martinius (Master thesis, 2019)
      For personer med diabetes mellitus er det avgjørende å holde blodsukkernivået innenfor det anbefalte området etter måltider. Mange gjør dette ved selv å telle karbohydrater, og deretter bestemme mengden insulin som skal ...
    • Parametrisk usikkerhet i modellbasert regulering 

      Sæle, Ludvig Stangeland (Master thesis, 2019)
      Denne oppgaven tar i betraktning arbeidet utført på APT-simulatoren som Hans Erik Frøyen startet på i sin masteroppgave. Nicolay Erlbeck og Karl Arthur Unstad videreutviklet denne simulatoren i sine oppgaver. Oppgaven ...
    • Pattern recognition reveals characteristic postprandial glucose changes: Non-individualized meal detection in diabetes mellitus type 1 

      Kölle, Konstanze; Biester, Torben; Christiansen, Sverre; Fougner, Anders Lyngvi; Stavdahl, Øyvind (Journal article; Peer reviewed, 2019)
      Accurate continuous glucose monitoring (CGM) is essential for fully automated glucose control in diabetes mellitus type 1. State-of-the-art glucose control systems automatically regulate the basal insulin infusion. Users ...
    • Physiological effects of intraperitoneal versus subcutaneous insulin infusion in patients with diabetes mellitus type 1: A systematic review and meta-analysis 

      Dirnena-Fusini, Ilze; Åm, Marte Kierulf; Fougner, Anders Lyngvi; Carlsen, Sven Magnus; Christiansen, Sverre Christian (Peer reviewed; Journal article, 2021)
      The intraperitoneal route of administration accounts for less than 1% of insulin treatment regimes in patients with diabetes mellitus type 1 (DM1). Despite being used for decades, a systematic review of various physiological ...
    • Pilot study of Early Meal Onset Detection from Abdominal Sounds 

      Setti, Sunilkumar Telagam; Søiland, Elise; Stavdahl, Øyvind; Fougner, Anders Lyngvi (Chapter, 2019)
      A typical artificial pancreas depends only on the continuous glucose monitoring (CGM) value for insulin dosing. However, both the insulin infusion and the glucose sensing are subject to time delays and slow dynamics. An ...
    • Proportional Myoelectric Control of a Multifunction Upper-limb Prosthesis 

      Fougner, Anders Lyngvi (Master thesis, 2007)
      This study is a part of a renew and continuation of the SVEN work done in Sweden in the later 1970's. The SVEN hand was an on/off-controlled upper-limb prosthesis based on measured electromyographic (EMG) signals. Recently ...
    • Resolving the Limb Position Effect in Myoelectric Pattern Recognition 

      Fougner, Anders Lyngvi; Scheme, Erik; Chan, Adrian D. C.; Englehart, Kevin; Stavdahl, Øyvind (Journal article; Peer reviewed, 2011)
      Reported studies on pattern recognition of electromyograms (EMG) for the control of prosthetic devices traditionally focus on classification accuracy of signals recorded in a laboratory. The difference between the constrained ...
    • Risk Analysis for the Design of a Safe Artificial Pancreas Control System 

      Kölle, Konstanze; Fougner, Anders Lyngvi; Lundteigen, Mary Ann; Carlsen, Sven Magnus; Ellingsen, Reinold; Stavdahl, Øyvind (Journal article; Peer reviewed, 2018)
      Closed-loop glucose control has the potential to improve the glycemic control in patients with diabetes mellitus type 1. Such an artificial pancreas (AP) should keep the user safe despite all disturbances and faults. The ...
    • Simple Nonlinear Models for Glucose-Insulin Dynamics: Application to Intraperitoneal Insulin Infusion 

      Lopez Zazueta, Claudia; Stavdahl, Øyvind; Fougner, Anders Lyngvi (Journal article; Peer reviewed, 2019)
      The design of a model-based control method for an Artificial Pancreas requires a relatively simple and identifiable mathematical model to control glucose levels through hormone delivery. In this work we introduce new, ...
    • System Training and Assessment in Simultaneous Proportional Myoelectric Prosthesis Control 

      Fougner, Anders Lyngvi; Stavdahl, Øyvind; Kyberd, Peter Joseph (Journal article; Peer reviewed, 2014)
      Background Pattern recognition control of prosthetic hands take inputs from one or more myoelectric sensors and controls one or more degrees of freedom. However, most systems created allow only sequential control of one ...
    • The Artificial Pancreas: A Dynamic Challenge 

      Stavdahl, Øyvind; Fougner, Anders Lyngvi; Kölle, Konstanze; Christiansen, Sverre Christian; Ellingsen, Reinold; Carlsen, Sven Magnus (Journal article; Peer reviewed, 2016)
      In patients with diabetes mellitus type 1, the pancreatic insulin production ceases, causing raise in blood glucose level (BGL) and potentially severe long-term complications. The “holy grail” of diabetes treatment is the ...
    • Why intraperitoneal glucose sensing is sometimes surprisingly rapid and sometimes slow: A hypothesis 

      Åm, Marte Kierulf; Fougner, Anders Lyngvi; Ellingsen, Reinold; Hjelme, Dag Roar; Bösch, Patrick Christian; Stavdahl, Øyvind; Carlsen, Sven Magnus; Christiansen, Sverre (Journal article; Peer reviewed, 2019)
      The artificial pancreas requires fast and reliable glucose measurements. The peritoneal space has shown promising results, and in one of our studies we detected glucose changes in the peritoneal space already at the same ...
