Modelling and detection of occlusion in insulin pumps and artificial pancreas systems
Formo, Mads Wikmark (Master thesis, 2021) -
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 ... -
Modelling and simulation of occlusions in insulin pumps
Formo, Mads Wikmark; Stavdahl, Øyvind; Fougner, Anders Lyngvi (Chapter, 2021)Abstract — An open source simulation model of the mechanical properties of a fully functional insulin pump was made in Matlab Simscape. The model simulates realistic behavior of an insulin pump, parts of which are validated ... -
A Nonlinear State Observer for the Bi-Hormonal Intraperitoneal Artificial Pancreas
Davari Benam, Karim; Khoshamadi, Hasti; Lema-Pérez, Laura; Gros, Sebastien; Fougner, Anders Lyngvi (Chapter, 2022)Currently, continuous glucose monitoring sensors are used in the artificial pancreas to monitor blood glucose levels. However, insulin and glucagon concentrations in different parts of the body cannot be measured in ... -
Optimal Experimental Design for System Identification in a Bi-Hormonal Intraperitoneal Artificial Pancreas
Engell, Sarah Ellinor; Davari Benam, Karim; Bengtsson, Henrik; Jørgensen, John Bagterp; Fougner, Anders Lyngvi (Chapter, 2024) -
Optimal Experimental Design to Estimate Insulin Response in Type 2 Diabetes
Engell, Sarah Ellinor; Bengtsson, Henrik; Davari Benam, Karim; Fougner, Anders Lyngvi; Jørgensen, John Bagterp (Chapter, 2023)In late-stage type 2 diabetes, automated titration algorithms provide a promising alternative to the current standard-of-care. Many published methods rely on personalized dose-response models to predict a safe and effective ... -
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 ... -
